bash-3.2-beta. - -1. Changes to Bash - -a. Fixed a bug that caused the temporary environment passed to a command to - affect the shell's environment under certain circumstances. - -b. Fixed a bug in the printf builtin that caused the %q format specifier to - ignore empty string arguments. - -c. Improved multibyte character environment detection at configuration time. - -d. Fixed a bug in the read builtin that left spurious escape characters in the - input after processing backslashes when assigning to an array variable. - -2. Changes to Readline - -a. Fixed a redisplay bug that occurred in multibyte-capable locales when the - prompt was one character longer than the screen width. ------------------------------------------------------------------------------- -This document details the changes between this version, bash-3.2-beta, -and the previous version, bash-3.2-alpha. - -1. Changes to Bash - -a. Changed the lexical analyzer to treat locale-specific blank characters as - white space. - -b. Fixed a bug in command printing to avoid confusion between redirections and - process substitution. - -c. Fixed problems with cross-compiling originating from inherited environment - variables. - -d. Added write error reporting to printf builtin. - -e. Fixed a bug in the variable expansion code that could cause a core dump in - a multi-byte locale. - -f. Fixed a bug that caused substring expansion of a null string to return - incorrect results. - -g. BASH_COMMAND now retains its previous value while executing commands as the - result of a trap, as the documentation states. - -2. Changes to Readline - -a. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing - the prompt and input line multiple times. - -b. Fixed history expansion to not be confused by here-string redirection. - -c. Readline no longer treats read errors by converting them to newlines, as - it does with EOF. This caused partial lines to be returned from readline(). - ------------------------------------------------------------------------------- -This document details the changes between this version, bash-3.2-alpha, -and the previous version, bash-3.1-release. - -1. Changes to Bash - -a. Fixed a source bug that caused the minimal configuration to not compile. - -b. Fixed memory leaks in error handling for the `read' builtin. - -c. Changed the [[ and (( compound commands to set PIPESTATUS with their exit - status. - -d. Fixed some parsing problems with compound array assignments. - -e. Added additional configuration changes for: NetBSD (incomplete multibyte - character support) - -f. Fixed two bugs with local array variable creation when shadowing a variable - of the same name from a previous context. - -g. Fixed the `read' builtin to restore the correct set of completion functions - if a timeout occurs. - -h. Added code to defer the initialization of HISTSIZE (and its stifling of the - history list) until the history file is loaded, allowing a startup file to - override the default value. - -i. Tightened up the arithmetic expression parsing to produce better error - messages when presented with invalid operators. - -j. Fixed the cross-compilation support to build the signal list at shell - invocation rather than compile time if cross-compiling. - -k. Fixed multibyte support for non-gcc compilers (or compilers that do not - allow automatic array variable sizing based on a non-constant value). - -l. Several fixes to the code that manages the list of terminated jobs and - their exit statuses, and the list of active and recently-terminated jobs - to avoid pid aliasing/wraparound and allocation errors. - -m. Fixed a problem that allowed scripts to die due to SIGINT while waiting - for children, even when started in the background or otherwise ignoring - SIGINT. - -n. Fixed a bug that caused shells invoked as -/bin/bash from not being - recognized as login shells. - -o. Fixed a problem that caused shells in the background to give the terminal - to a process group other than the foreground shell process group. - -p. Fixed a problem with extracting the `varname' in ${#varname}. - -q. Fixed the code that handles SIGQUIT to not exit immediately -- thereby - calling functions that may not be called in a signal handler context -- - but set a flag and exit afterward (like SIGINT). - -r. Changed the brace expansion code to skip over braces that don't begin a - valid matched brace expansion construct. - -s. Fixed `typeset' and `declare' to not require that their shell function - operands to be valid shell identifiers. - -t. Changed `test' to use access(2) with a temporary uid/euid swap when testing - file attributes and running setuid, and access(2) in most other cases. - -u. Changed completion code to not attempt command name completion on a line - consisting solely of whitespace when no_empty_command_completion is set. - -v. The `hash' builtin now prints nothing in posix mode when the hash table is - empty, and prints a message to that effect to stdout instead of stderr - when not in posix mode. - -w. Fixed a bug in the extended pattern matching code that caused it to fail to - match periods with certain patterns. - -x. Fixed a bug that caused the shell to dump core when performing filename - generation in directories with thousands of files. - -y. Returned to the original Bourne shell rules for parsing ``: no recursive - parsing of embedded quoted strings or ${...} constructs. - -z. The inheritence of the DEBUG, RETURN, and ERR traps is now dependent only - on the settings of the `functrace' and `errtrace' shell options, rather - than whether or not the shell is in debugging mode. - -aa. Fixed a problem with $HOME being converted to ~ in the expansion of - members of the DIRSTACK array. - -bb. Fixed a problem with quoted arguments to arithmetic expansions in certain - constructs. - -cc. The command word completion code now no longer returns matching directories - while searching $PATH. - -dd. Fixed a bug with zero-padding and precision handling in snprintf() - replacement. - -ee. Fixed a bug that caused the command substitution code not to take embedded - shell comments into account. - -ff. Fixed a bug that caused $((...);(...)) to be misinterpreted as an - arithmetic substitution. - -gg. Fixed a bug in the prompt expansion code that inappropriately added a - \001 before a \002 under certain circumstances. - -hh. Fixed a bug that caused `unset LANG' to not properly reset the locale - (previous versions would set the locale back to what it was when bash - was started rather than the system's "native" locale). - -ii. Fixed a bug that could cause file descriptors > 10 to not be closed even - when closed explicitly by a script. - -jj. Fixed a bug that caused single quotes to be stripped from ANSI-C quoting - inside double-quoted command substitutions. - -kk. Fixed a bug that could cause core dumps when `return' was executed as the - last element of a pipeline inside a shell function. - -ll. Fixed a bug that caused DEBUG trap strings to overwrite commands stored in - the jobs list. - -2. Changes to Readline - -a. Fixed a problem that caused segmentation faults when using readline in - callback mode and typing consecutive DEL characters on an empty line. - -b.

Fixed output of key bindings (like bash `bind -p') to honor the setting of - convert-meta and use \e where appropriate. - -h. Changed the default filename completion function to call the filename - dequoting function if the directory completion hook isn't set. This means - that any directory completion hooks need to dequote the directory name, - since application-specific hooks need to know how the word was quoted, - even if no other changes are made. - -i. Fixed a bug with creating the prompt for a non-interactive search string - when there are non-printing characters in the primary prompt. - -j. Fixed a bug that caused prompts with invisible characters to be redrawn - multiple times in a multibyte locale. - -k. Fixed a bug that could cause the key sequence scanning code to return the - wrong function. - -l.

Fixed a bug that could cause a core dump when an edited history entry was - re-executed under certain conditions. - -n. Fixed a bug that caused readline to reference freed memory when attmpting - to display a portion of the prompt. - -3. New Features in Bash - -a. Changed the parameter pattern replacement functions to not anchor the - pattern at the beginning of the string if doing global replacement - that - combination doesn't make any sense. - -b. When running in `word expansion only' mode (--wordexp option), inhibit - process substitution. - -c. Loadable builtins now work on MacOS X 10.[34]. - -d. Shells running in posix mode no longer set $HOME, as POSIX requires. - -e. The code that checks for binary files being executed as shell scripts now - checks only for NUL rather than any non-printing character. - -f. Quoting the string argument to the [[ command's =~ operator now forces - string matching, as with the other pattern-matching operators. - -4. New Features in Readline - -a. Calling applications can now set the keyboard timeout to 0, allowing - poll-like behavior. - -b. The value of SYS_INPUTRC (configurable at compilation time) is now used as - the default last-ditch startup file. - -c. The history file reading functions now allow windows-like \r\n line - terminators. - ------------------------------------------------------------------------------- This document details the changes between this version, bash-3.1-release, and the previous version, bash-3.1-rc2. @@ -306,7 +48,7 @@ and the previous version, bash-3.1-beta1. 1.

Fix from William Bader - -aclocal.m4 - - add check for localeconv to AM_INTL_SUBDIR macro - -config.h.in - - add HAVE_LOCALECONV - -lib/sh/snprintf.c - - add check for HAVE_LOCALECONV for GETLOCALEDATA macro - -general.[ch] - - first argument to legal_number is now `const char *' - - 11/14 - ----- -lib/readline/{readline,rlprivate}.h - - move rl_display_prompt declaration from rlprivate.h to readline.h - -lib/readline/util.h - - new function: rl_free(void *mem), for use by users of readline dlls - on Windows - -lib/readline/readline.h - - new extern declaration for rl_free - -lib/readline/doc/rltech.texi - - document rl_free and rl_display_prompt for use by application writers - - 11/15 - ----- -aclocal.m4 - - change tests for /dev/fd and /dev/stdin to use constructs of the form - (exec test ... ) instead of test ... to avoid bash's /dev/fd and - /dev/stdin emulation - - 11/16 - ----- -jobs.c - - in delete_job, reset_current was being called before the job slot - was cleared -- moved after job_slots[job] was set to NULL. Fixes - bug reported by Dan Jacobson - - 11/19 - ----- -findcmd.c - - when the checkhash option is set, fix the check for the hashed - pathname being an existing executable file. Old code required a - hash table deletion and re-addition. Bug reported by Linda - Walsh - - 11/21 - ----- -subst.c - - in pos_params, handle case of `start' == 0 by making the list of - positional parameters begin with $0 - - in parameter_brace_substring, increment `len' if start == 0, sicne - we will be adding $0 to the beginning of the list when we process it - -doc/{bash.1,bashref.texi} - - document new behavior of `0' offset when using substring expansion - with the positional parameters - -support/shobj-conf - - changes to shared object creation for loadable builtins on Mac OS X - 10.4 to use libtool instead of ld by specifying -dynamiclib - argument and changing options to be appropriate for libtool. This - winds up creating a dynamic shared library instead of an executable - - 11/24 - ----- -{jobs,nojobs}.c - - don't set last_asynchronous_pid to the child's pid in the child - for asynchronous jobs (for compatibility -- all other posix shells - seem to do it this way). This means that (echo $! )& echo $! should - display two different pids. Fix from discussion on the - austin-group-l list - -builtins/mkbuiltins.c - - change builtins.c file generation so short doc strings are marked for - gettext and available for subsequent translation. Suggestion by - Benno Schulenberg - -builtins/{bind,cd,hash,inlib,printf,pushd,test,times,ulimit}.def -lib/malloc/malloc.c -{shell,subst}.c - - fix a few strings that were not marked as translatable. Fix from - Benno Schulenberg - -lib/readline/misc.c - - new function, _rl_revert_all_lines(void). Goes through history, - reverting all entries to their initial state by undoing any undo - lists. - -lib/readline/rlprivate.h - - extern declaration for _rl_revert_all_lines - -rldefs.h - - add #undef HAVE_STRCOLL if STRCOLL_BROKEN is defined, prep to move - from config.h.in. Problem reported by Valerly Ushakov - - - 11/25 - ----- -lib/readline/readline.c - - call _rl_revert_all_lines from readline_internal_teardown if the - variable _rl_revert_all_at_newline is non-zero - - declare _rl_revert_all_lines initially 0 - - 11/27 - ----- -doc/{bash.1,bashref.texi} - - make sure to be explicit that `typeset +r' cannot remove the readonly - attribute from a variable - - 11/28 - ----- -lib/sh/zmapfd.c - - new file, implements zmapfd(), which takes a file and returns its - contents in a string - -externs.h - - extern declaration for zmapfd - - 11/29 - ----- -builtins/evalfile.c - - in _evalfile, use zmapfd to read the contents of the file into a - string, rather than using the size reported by stat and reading that - many characters, if the file is not a regular file (for things like - named pipes, stat reports the size as 0) - - 12/3 - ---- -lib/sh/snprintf.c - - make sure number() sets the FL_UNSIGNED flag for %x and %X, so - fmtulong treats them as unsigned numbers. Fixes bug reported by - James Botte - - 12/13 - ----- -lib/readline/util.c - - new function, _rl_ttymsg, for internal warning messages -- does - redisplay after printing message - - new function, _rl_errmsg, for internal warning/error messages -- - does not do redisplay after printing message - -lib/readline/rlprivate.h - - new extern declaration for _rl_ttymsg, _rl_errmsg - -lib/readline/{bind,callback,complete,display,rltty}.c - - use _rl_ttymsg/_rl_errmsg instead of direct writes to stderr - -lib/sh/tmpfile.c - - in get_tmpdir(), make sure that $TMPDIR names a writable directory; - otherwise skip it. This catches names longer than PATH_MAX, but in - case it doesn't test that the length does not exceed PATH_MAX. Fixes - heap overrun bug reported by Eric Blake - - 12/16 - ----- -builtin/{set,declare,shopt,trap,wait,bind,complete,enable,fc,history,read,setattr}.def -doc/{bash.1,bashref.texi} - - improvements and clarifications to the help text associated with - several builtins, in some cases bringing them into line with the - man page text. From Benno Schulenberg - -doc/{bash.1,bashref.texi} - - add `E' and `T' to the synopsis of the set builtin. - From Benno Schulenberg - -builtins/{break,exit,fg_bg,hash,jobs,type,ulimit}.def -builtins/{common,evalfile}.c -{error,expr,jobs,mksyntax,nojobs,shell,subst,version,siglist}.c - - add gettextizing marks to untranslated strings - From Benno Schulenberg - - 12/19 - ----- -builtins/common.c - - change display_signal_list (used by `trap -l' and `kill -l') to use - five columns instead of 4 to display signal names - -builtins/help.def - - use the true terminal width instead of assuming 80 when displaying - help topics, leaving two characters of whitespace between horizontal - descriptions instead of 1 - - change to print in columns with entries sorted down rather than across - (that is, like `ls' rather than `ls -x'). Change inspired by Benno - Schulenberg - -jobs.h - - give values to the JOB_STATE enumerations so they can be used as - bitmasks, too - - 12/22 - ----- -doc/{bash.1,bashref.texi} - - change description of `set' to make it clearer that you can use - `+' to turn off options - - clarify in the description of word splitting that sequences of - IFS whitespace at the beginning or end of the string are ignored - - 12/26 - ----- -doc/bashref.texi - - move `shopt' builtin to its own section; change internal references - from `Bash Builtins' to the new shopt builtin - - new section for builtins that modify shell behavior in `Shell - Builtin Commands'; move set and shopt to new section. Changes - inspired by Benno Schulenberg - -{redir,subst}.c - - add MT_USETMPDIR flag to calls to sh_mktmpfd and sh_mktmpname. Bug - reported by Eric Blake - -{configure,Makefile}.in - - changes so that the pathname for DEBUGGER_START_FILE is substituted - into pathnames.h at make time (allowing more flexibility in setting - `prefix' or `datadir') instead of at configure time. Suggested by - Nick Brown - -shell.c - - declaration for have_devfd; initialized from HAVE_DEV_FD - - declaration for check_jobs_at_exit; initialized to 0 - - declaration for autocd; initialized to 0 - -variables.c - - new dynamic variable, BASHPID, always set from return value from - getpid() (changes even when $$ doesn't change). Idea from Bruce - Korb - -builtins/exit.def - - if check_jobs_at_exit is non-zero, list jobs if there are any stopped - or running background jobs; don't exit shell if any running jobs - -execute_cmd.c - - in execute_simple_command, if the first word of a simple command is - a directory name (after looking for builtins, so `.' isn't caught) - that isn't found in $PATH, and `autocd' is non-zero, prefix a "cd" - to the command words - -builtins/shopt.def - - new `checkjobs' option, changes value of check_jobs_at_exit - - new `autocd' option, changes value of autocd - -pcomplete.c - - add COMP_TYPE, set to rl_completion_type, to list of variables set - by bind_compfunc_variables and unset by unbind_compfunc_variables - -doc/{bash.1,bashref.texi} - - document BASHPID - - document new shopt `checkjobs' option - - document new shopt `autocd' option - - document COMP_TYPE completion variable - - 12/29 - ----- -aclocal.m4 - - in BASH_SYS_SIGLIST, check HAVE_DECL_SYS_SIGLIST instead of the - obsolete and no-longer-supported SYS_SIGLIST_DECLARED - - 12/30 - ----- -lib/readline/vi_mode.c - - add ` (backquote) to the list of vi motion characters - - in rl_vi_delete_to, rl_vi_change_to, and rl_vi_yank_to, don't delete - character under the cursor if the motion command moves the cursor - backward, so add F and T to the commands that don't cause the - mark to be adjusted - - add ` to the characters that don't cause the mark to be adjusted - when used as a motion command, since it's defined to behave that way - - when a motion character that may adjust the mark moves point - backward, don't adjust the mark so the character under the cursor - isn't deleted - -lib/readline/complete.c - - add variable rl_sort_completion_matches; allows application to - inhibit match list sorting - - add variable rl_completion_invoking_key; allows applications to - discover the key that invoked rl_complete or rl_menu_complete - -lib/readline/readline.h - - extern declarations for rl_completion_invoking_key and - rl_sort_completion_matches - -lib/readline/doc/rltech.texi - - documented rl_completion_invoking_key and rl_sort_completion_matches - -pcomplete.c - - export variable COMP_KEY to completion functions; initialized from - rl_completion_invoking_key; unset along with rest of completion - variables - -doc/{bash.1,bashref.texi},lib/readline/doc/rluser.texi - - document COMP_KEY - -[many files] - - changes to make variables and function parameters `const' for better - text sharing.

Corresponding changes to dequote_escapes. - Fixes a couple of problems reported by Brett Stahlman - - - 1/14 - ---- -subst.c - - make same change to read_comsub to add CTLESC before ' ' if $IFS is - null, since we will split on literal spaces later - - 1/15 - ---- -array.c - - new function, array_quote_escapes (ARRAY *a), calls quote_escapes - on each element of the array in the same way array_quote calls - quote_string - - call array_quote_escapes if match is not quoted in array_patsub - - array_slice is now used, so remove the #ifdef INCLUDE_UNUSED define - - change structure of array_subrange to call array_slice to create a - new array with the desired subset of elements, then call array_quote - or array_quote_escapes as necessary, like array_patsub. Convert to - a string by calling array_to_string on the sliced-out array - -array.h - - new extern declaration for array_quote_escapes - -subst.c - - since array_patsub now calls quote_escapes as necessary, callers - don't need to call it after array_patsub returns.

Solaris's loopback mount implementation breaks some of the - file system assumptions the replacement getcwd uses. - -builtins/common.c - - if GETCWD_BROKEN is defined, call getcwd with PATH_MAX for the size - argument, so it will allocate a buffer for the current working dir - with that size, instead of one that's `big enough' - -config.h.in - - add #undef PRI_MACROS_BROKEN for AIX 4.3.3 - -pathexp.h - - new flag value for quote_string_for_globbing: QGLOB_REGEXP (quoting - an ERE for matching as a string) - -pathexp.c - - change quote_string_for_globbing to understand QGLOB_REGEXP - -execute_cmd.c - - change execute_cond_node to pass 2 (regexp match), 1 (shell pattern - match), or 0 (no matching) to cond_expand_word - -subst.c - - change cond_expand_word to translate SPECIAL==2 into passing - QGLOB_REGEXP to quote_string_for_globbing - - 2/2 - --- -builtins/printf.def - - if PRI_MACROS_BROKEN is defined, #undef PRIdMAX (AIX 4.3.3 broken) - - 2/3 - --- -Makefile.in,{builtins,doc}/Makefile.in,lib/*/Makefile.in - - add assignment for datarootdir as per GNU coding standards - -Makefile.in,builtins/Makefile.in,lib/intl/Makefile.in,po/Makefile.in.in - - use @localedir@ instead of $(datadir)/locale in assignment - - 2/13 - ---- -jobs.c - - fix compact_jobs_list to not return js.j_lastj, since that is in use - and should not be overwritten. Fix from Len Lattanzi - - - 2/16 - ---- -lib/readline/text.c - - change rl_forward_char to allow moving to the end of the line when - using the arrow keys in vi insertion mode, rather than having the - behavior identical between vi command and insertion modes.

Fixes - bug reported by Ian Watson - -lib/readline/display.c - - in _rl_move_cursor_relative, use `new' when comparing against - the last invisible character in the prompt, since they both denote - buffer indices when in a multibyte locale, whereas `dpos' is a - display position - - 3/13 - ---- -lib/readline/complete.c - - set rl_completion_append_character to the default (' ') in - set_completion_defaults(). Fixes bug reported by David Emerson - - - 3/23 - ---- -builtins/evalfile.c - - make sure read() returns a value >= 0 before using it as an index - into string[] - - use a variable of type `ssize_t' for return value from read() - - only try to read the entire contents of a regular file in one shot - if the file size is less than SSIZE_MAX. These fix problems - reported by hooanon05@yahoo.co.jp. - -include/typemax.h - - define SSIZE_MAX as 32767 if it's not defined - -lib/readline/display.c - - in rl_redisplay() and update_line(), if redrawing the prompt because - it contains invisible characters, make sure we redraw the character - indicating a modified history line and take it into account when - computing _rl_last_c_pos - - in update_line, if deleting characters and redrawing the new text, - make sure we adjust _rl_last_c_pos by wrap_offset in a multibyte - locale if the text we're drawing starts before or at the last - invisible character in the prompt string. Fixes bug reported on - bug-readline by J Pelkey - -parse.y - - when adding at CTLESC character to the current token, do not - escape it with CTLESC if pass_next_character indicates that the - CTLESC was escaped by a backslash.

The Free Translation Project +is a way to get maintainers of free software, translators, and users all +together, so that will gradually become able to speak many languages. +A few packages already provide translations for their messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work at translations should contact the appropriate team. + + When reporting bugs in the `intl/' directory or bugs which may be +related to internationalization, you should tell about the version of +`gettext' which is used. The information can be found in the +`intl/VERSION' file, in internationalized packages. + +Quick configuration advice +========================== + + If you want to exploit the full power of internationalization, you +should configure it using + + ./configure --with-included-gettext + +to force usage of internationalizing routines provided within this +package, despite the existence of internationalizing capabilities in the +operating system where this package is being installed. So far, only +the `gettext' implementation in the GNU C library version 2 provides as +many features (such as locale alias, message inheritance, automatic +charset conversion or plural form handling) as the implementation here. +It is also not possible to offer this additional functionality on top +of a `catgets' implementation. Future versions of GNU `gettext' will +very likely convey even more functionality. So it might be a good idea +to change to GNU `gettext' as soon as possible. + + So you need _not_ provide this option if you are using GNU libc 2 or +you have installed a recent copy of the GNU gettext package with the +included `libintl'. + +INSTALL Matters +=============== + + Some packages are "localizable" when properly installed; the +programs they contain can be made to speak your own native language. +Most such packages use GNU `gettext'. Other packages have their own +ways to internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. If not, the GNU `gettext' own +library will be used. This library is wholly contained within this +package, usually in the `intl/' subdirectory, so prior installation of +the GNU `gettext' package is _not_ required. Installers may use +special options at configuration time for changing the default +behaviour. The commands: + + ./configure --with-included-gettext + ./configure --disable-nls + +will respectively bypass any pre-existing `gettext' to use the +internationalizing routines provided within this package, or else, +_totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl.a' file and +will decide to use this. This might be not what is desirable. You +should use the more recent version of the GNU `gettext' library. I.e. +if the file `intl/VERSION' shows that the library which comes with this +package is more recent, you should use + + ./configure --with-included-gettext + +to prevent auto-detection. + + The configuration process will not test for the `catgets' function +and therefore it will not be used. The reason is that even an +emulation of `gettext' on top of `catgets' could not provide all the +extensions of the GNU `gettext' library. + + Internationalized packages have usually many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +Using This Package +================== + + As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code, +and `CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your country by running the command +`locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +Translating Teams +================= + + For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams" +area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `translation@iro.umontreal.ca' to reach the +coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skill are praised more than +programming skill, here. + +Available Packages +================== + + Languages are not equally supported in all packages.

This is because a few extra PO files are +used for implementing regional variants of languages, or language +dialects. + + For a PO file in the matrix above to be effective, the package to +which it applies should also have been internationalized and +distributed as such by its maintainer. There might be an observable +lag between the mere existence a PO file and its wide availability in a +distribution. + + If May 2003 seems to be old, you may fetch a more recent copy of +this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date +matrix with full percentage details can be found at +`http://www.iro.umontreal.ca/contrib/po/HTML/matrix.html'. + +Using `gettext' in new packages +=============================== + + If you are writing a freely available program and want to +internationalize it you are welcome to use GNU `gettext' in your +package. Of course you have to respect the GNU Library General Public +License which covers the use of the GNU `gettext' library. This means +in particular that even non-free programs can use `libintl' as a shared +library, whereas only free software can use `libintl' as a static +library or use modified versions of `libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of `gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project. Contact +`translation@iro.umontreal.ca' to make the `.pot' files available to +the translation teams. + diff --git a/bash-20060316/AUTHORS b/bash-20060316/AUTHORS new file mode 100644 index

Changes to Bash + +a. Fixed a bug that caused a DEBUG trap to overwrite a command string that's + eventually attached to a background job. + +b. Changed some code so that filenames with leading tildes with spaces in the + name aren't tilde-expanded by the bash completion code. + +c. Fixed a bug that caused the pushd builtin to fail to change to + directories with leading `-'. + +d. Fixed a small memory leak in the programmable completion code. + +2. Changes to Readline + +a. Fixed a redisplay bug caused by moving the cursor vertically to a line + with invisible characters in the prompt in a multibyte locale. + +b. Fixed a bug that could cause the terminal special chars to be bound in the + wrong keymap in vi mode. + +3. New Features in Bash + +a. If compiled for strict POSIX conformance, LINES and COLUMNS may now + override the true terminal size. + +4. New Features in Readline + +a. A new external application-controllable variable that allows the LINES + and COLUMNS environment variables to set the window size regardless of + what the kernel returns. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-3.1-rc1, +and the previous version, bash-3.1-beta1. + +1. Changes to Bash + +a. Fixed a bug that could cause core dumps due of accessing the current + pipeline while in the middle of modifying it. + +b. Fixed a bug that caused pathnames with backslashes still quoting characters + to be passed to opendir(). + +c. Command word completion now obeys the setting of completion-ignore-case. + +d. Fixed a problem with redirection that caused file descriptors greater than + 2 to be inappropriately marked as close-on-exec. + +e. In Posix mode, after `wait' is called to wait for a particular process + explicitly, that process is removed from the list of processes known to + the shell, and subsequent attempts to wait for it return errors. + +f. Fixed a bug that caused extended pattern matching to incorrectly scan + backslash-escaped pattern characters. + +g. Fixed a synchronization problem that could cause core dumps when handling + a SIGWINCH. + +h. Fixed a bug that caused an unmatched backquote to be accepted without an + error when processing here documents. + +i. Fixed a small memory leak in the `cd' builtin. + +j. Fix for MacOS X so it gets the values for the HOSTTYPE, MACHTYPE, and + OSTYPE variables at build time, to support universal binaries. + +k. Fixed a bug that could cause an exit trap to return the exit status of + the trap command rather than the status as it was before the trap was + run as the shell's exit status. + +2. New Features in Bash + +3. Changes to Readline + +a. Fixed a bug that caused reversing the incremental search direction to + not work correctly. + +b. Fixed the vi-mode `U' command to only undo up to the first time insert mode + was entered, as Posix specifies. + +c. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong + place. + +4. New Features in Readline + +a. New application-callable auxiliary function, rl_variable_value, returns + a string corresponding to a readline variable's value. + +b. When parsing inputrc files and variable binding commands, the parser + strips trailing whitespace from values assigned to boolean variables + before checking them. + + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-3.1-beta1, +and the previous version, bash-3.1-alpha1. + +1.

Make sure changes to variables bash handles specially (e.g., LC_ALL) are + made when the variable is modified using `printf -v'. + +g. The export environment is now remade on cygwin when HOME is changed, so + DLLs bash is linked against pick up the new value. This fixes problems + with tilde expansion when linking against and already-installed readline. + +h. Small fix to the logic for performing tilde expansion in posix mode, so + expansion on the right-hand side of an assignment statement takes place. + +i. Fixed a bug that prevented redirections associated with a shell function + from being executed when in a subshell. + +j. Fixed `source' and `.' builtins to not require an executable file when + searching $PATH for a file to source. + +k.

Fixed a problem with the `type' and `command' builtins that caused absolute + pathnames to be displayed incorrectly. + +p. Some changes to the `bg' builtin for POSIX conformance. + +q. The `fc' builtin now removes the `fc' command that caused it to invoke an + editor on specified history entries from the history entirely, rather than + simply ignoring it. + +r.

The code that scans embedded commands for the parser (`...` and $(...)) is + now more aware of embedded comments and their effect on quoted strings. + +y. Changed the `-n' option to the `history' builtin to not reset the number of + history lines read in the current session after reading the new lines from + the history file if the history is being appended when it is written to + the file, since the appending takes care of the problem that the adjustment + was intended to solve. + +z. Improved the error message displayed when a shell script fails to execute + because the environment and size of command line arguments are too large. + +aa. A small fix to make sure that $HISTCMD is evaluated whenever the shell is + saving commands to the history list, not just when HISTSIZE is defined. + +2. Changes to Readline + +a.

Fixed a bug that caused the `==' operator to the [[ command to not attempt + extended pattern matching. + +l. Fixed the brace expansion code to handle characters whose value exceeds 128. + +m. Fixed `printf' to handle strings with a leading `\0' whose length is + non-zero. + +n. Fixed a couple of problems with brace expansion where `${' was handled + incorrectly. + +o. Fixed off-by-one error when calculating the upper bound of `offset' when + processing the ${array[@]:offset:length} expansion. + +p. System-specific configuration changes for: FreeBSD 5.x, Interix, MacOS X + 10.4, Linux 2.4+ kernels, Linux 3.x kernels, Dragonfly BSD, QNX 6.x, + Cygwin + +q.

Fixed a completion bug that caused core dumps when expanding a directory + name. + +s. Fixed a bug that prevented `hash -d' from removing commands from the hash + table. + +t. Fixed word splitting to avoid really bad quadratic performance when + expanding long lists. + +u. Fixed a bug that caused negative offsets in substring expansion to use the + wrong values. + +v. Fixed a bug in printf that caused it to not return failure on write errors. + +w. Fixed a bug that caused commands in subshells to not be properly timed. + +x. The shell parser no longer attempts to parse a compound assignment specially + unless in a position where an assignment statement is acceptable or parsing + arguments to a builtin that accepts assignment statements. + +y. Fixed a problem that caused a `case' statement to be added to the history + incorrectly as a single command if the `case word' was on one line and the + `in' on another. + +z. Fixed a problem that caused internal shell quoting characters to be + incorrectly quoted with backslashes under some circumstances. + +aa. The shell now performs correct word splitting when IFS contains multibyte + characters. + +bb. The mail checking code now resets the cached file information if the size + drops to 0, even if the times don't change. + +cc. A completed command name that is found in $PATH as well as the name of a + directory in the current directory no longer has a slash appended in certain + circumstances: a single instance found in $PATH when `.' is not in $PATH, + and multiple instances found in $PATH, even when `.' is in $PATH. + +dd. Incorporated tilde expansion into the word expansion code rather than as a + separately-called function, fixing some cases where it was performed + inappropriately (e.g., after the second `=' in an assignment statement or + in a double-quoted parameter expansion). + +ee. Fixed several bugs encountered when parsing compound assignment statements, + so that compound assignments appearing as arguments to builtins are no + longer double-expanded. + +ff. Fixed a bug in the command execution code that caused asynchronous commands + containing command substitutions to not put the terminal in the wrong + process group. + +gg. Bash now handles the case where the WCONTINUED flag causes waitpid() to + return -1/EINVAL at runtime as well as configuration time. + +hh. Fixed parser to generate an error when the pipeline `argument' to `!' or + `time' is NULL. + +ii. The shell now takes a little more care when manipulating file descriptors + greater than 9 with the `exec' builtin. + +jj. Fixed a bug that caused variable assignments preceding the `command' builtin + preceding a special builtin to be preserved after the command completed in + POSIX mode. + +kk. Fixed a bug that allowed variables beginning with a digit to be created. + +ll. Fixed a bug that caused a \ to be removed when parsing a $'...' + construct. + +mm.

Fixed a long-standing bug that caused '\177' characters in variable + values to be discarded when expanded in double-quoted strings. + +uu. Fixed a bug that caused $RANDOM to be re-seeded multiple times in a + subshell environment. + +vv. Extensive changes to the job management code to avoid the pid-reuse and + pid-aliasing problems caused by retaining the exit status of too many jobs, + but still retain as many background job statuses as POSIX requires. + +ww. Fixed a parser bug in processing \ that caused things like + + ((echo 5) \ + (echo 6)) + + to not work correctly. + +xx. `pwd -P' now sets $PWD to a directory name containing no symbolic links + when in posix mode, as POSIX requires. + +yy. In posix mode, bash no longer sets $PWD to a name containing no symbolic + links if a directory is chosen from $CDPATH. + +zz. The word splitting code now treats an IFS character that is not space, + tab, or newline and any adjacent IFS white space as a single delimiter, as + SUSv3/XPG6 require. + +aaa. The `read' builtin now checks whether or not the number of fields read is + exactly the same as the number of variables instead of just assigning the + rest of the line (minus any trailing IFS white space) to the last + variable. This is what POSIX/SUS/XPG all require. + +bbb. Fixed a bug that caused `read' to always check whether or not fd 0 was a + pipe, even when reading from another file descriptor. + +ccc. Fixed a bug that caused short-circuiting of execution even if the return + value was being inverted. + +ddd.

Fixed a bug so that a function definition in a pipeline causes a child + process to be forked at the right time. + +ggg. Bash will not attempt to link against a readline library that doesn't + have rl_gnu_readline_p == 1. + +hhh. Fixed a bug that caused `read' to consume one too many characters when + reading a fixed number of characters and the Nth character is a backslash. + +iii. Fixed a bug that caused `unset' on variables in the temporary environment + to leave them set when `unset' completed. + +jjj. Fixed a bug that caused bash to close fd 2 if an `exec' failed and the + shell didn't exit. + +kkk. The completion code is more careful to not turn `/' or `///' into `//', + for those systems on which `//' has special meaning. + +lll. Fixed a bug that caused command substitution in asynchronous commands to + close the wrong file descriptors. + +mmm. The shell no longer prints status messages about terminated background + processes unless job control is active. + +nnn. Fixed a bug that prevented multiple consecutive invocations of `history -s' + from adding all the commands to the history list. + +ooo. Added a couple of changes to make arithmetic expansion more consistent in + all its contexts (still not perfect). + +ppp. Fixed a bug that caused the parser to occasionally not find the right + terminating "`" in an old-style command substitution. + +qqq. Fixed a bug that caused core dumps when the shell was reading its non- + interactive input from fd 0 and fd 0 was duplicated and restored using a + combination of `exec' (to save) and redirection (to restore). + +rrr. Fixed a problem that caused loops in sourced scripts to not be cleaned + up properly when a `return' is executed. + +sss. Change internal command substitution completion function to append a slash + to directory names in the command. + +2. Changes to Readline + +a.

Fixed vi-mode searching so that failure preserves the current line rather + than the last line in the history list. + +e. Fixed the vi-mode `~' command (change-case) to have the correct behavior at + end-of-line when manipulating multibyte characters. + +f. Fixed the vi-mode `r' command (change-char) to have the correct behavior at + end-of-line when manipulating multibyte characters. + +g. Fixed multiple bugs in the redisplay of multibyte characters: displaying + prompts longer than the screen width containing multibyte characters, + +h. Fix the calculation of the number of physical characters in the prompt + string when it contains multibyte characters. + +i. A non-zero value for the `rl_complete_suppress_append' variable now causes + no `/' to be appended to a directory name. + +j. Fixed forward-word and backward-word to work when words contained + multibyte characters. + +k. Fixed a bug in finding the delimiter of a `?' substring when performing + history expansion in a locale that supports multibyte characters. + +l. Fixed a memory leak caused by not freeing the timestamp in a history entry. + +m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting + of the `convert-meta' variable. + +n. Fixed saving and restoring primary prompt when prompting for incremental + and non-incremental searches; search prompts now display multibyte + characters correctly. + +o. Fixed a bug that caused keys originally bound to self-insert but shadowed + by a multi-character key sequence to not be inserted. + +p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't + dereferenced if NULL (matching the documentation). + +q. Extensive changes to readline to add enough state so that commands + requiring additional characters (searches, multi-key sequences, numeric + arguments, commands requiring an additional specifier character like + vi-mode change-char, etc.) work without synchronously waiting for + additional input. + +r. Lots of changes so readline builds and runs on MinGW. + +s. Readline no longer tries to modify the terminal settings when running in + callback mode. + +t. The Readline display code no longer sets the location of the last invisible + character in the prompt if the \[\] sequence is empty. + +3. New Features in Bash + +a. Bash now understands LC_TIME as a special variable so that time display + tracks the current locale. + +b. BASH_ARGC, BASH_ARGV, BASH_SOURCE, and BASH_LINENO are no longer created + as `invisible' variables and may not be unset. + +c. In POSIX mode, if `xpg_echo' option is enabled, the `echo' builtin doesn't + try to interpret any options at all, as POSIX requires. + +d. The `bg' builtin now accepts multiple arguments, as POSIX seems to specify. + +e. Fixed vi-mode word completion and glob expansion to perform tilde + expansion. + +f. The `**' mathematic exponentiation operator is now right-associative. + +g. The `ulimit' builtin has new options: -i (max number of pending signals), + -q (max size of POSIX message queues), and -x (max number of file locks). + +h. A bare `%' once again expands to the current job when used as a job + specifier. + +i. The `+=' assignment operator (append to the value of a string or array) is + now supported for assignment statements and arguments to builtin commands + that accept assignment statements. + +j. BASH_COMMAND now preserves its value when a DEBUG trap is executed. + +k. The `gnu_errfmt' option is enabled automatically if the shell is running + in an emacs terminal window. + +l. New configuration option: --single-help-strings. Causes long help text + to be written as a single string; intended to ease translation. + +m. The COMP_WORDBREAKS variable now causes the list of word break characters + to be emptied when the variable is unset. + +n. An unquoted expansion of $* when $IFS is empty now causes the positional + parameters to be concatenated if the expansion doesn't undergo word + splitting. + +o. Bash now inherits $_ from the environment if it appears there at startup. + +p. New shell option: nocasematch. If non-zero, shell pattern matching ignores + case when used by `case' and `[[' commands. + +q. The `printf' builtin takes a new option: -v var. That causes the output + to be placed into var instead of on stdout. + +r. By default, the shell no longer reports processes dying from SIGPIPE. + +s. Bash now sets the extern variable `environ' to the export environment it + creates, so C library functions that call getenv() (and can't use the + shell-provided replacement) get current values of environment variables. + +4. New Features in Readline + +a. The key sequence sent by the keypad `delete' key is now automatically + bound to delete-char. + +b. A negative argument to menu-complete now cycles backward through the + completion list. + +c. A new bindable readline variable: bind-tty-special-chars. If non-zero, + readline will bind the terminal special characters to their readline + equivalents when it's called (on by default). + +d. New bindable command: vi-rubout. Saves deleted text for possible + reinsertion, as with any vi-mode `text modification' command; `X' is bound + to this in vi command mode. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-3.0-release, +and the previous version, bash-3.0-rc1. + +1. Changes to Bash + +a. Fixed a boundary overrun that could cause segmentation faults when the + completion code hands an incomplete construct to the word expansion + functions. + +b. Changed posix mode behavior so that an error in a variable assignment + preceding a special builtin causes a non-interactive shell to exit. + +c. Change the directory expansion portion of the completion code to not + expand embedded command substitutions if the directory name appears in + the file system. + +d. Fixed a problem that caused `bash -r' to turn on restrictions before + reading the startup files. + +e. Fixed a problem with the default operation of the `umask' builtin. + +2.

Changes to Bash + +a. Fixed a bug that caused incorrect behavior when referecing element 0 of + an array using $array, element 0 was unset, and `set -u' was enabled. + +b. System-specific changes for: SCO Unix 3.2, Tandem. + +c. Fixed a bug that caused inappropriate word splitting when a variable was + expanded within a double-quoted string that also included $@. + +d. Fixed a bug that caused `pwd' to not display anything in physical mode + when the file system had changed underneath the shell. + +e. Fixed a bug in the pre- and post- increment and decrement parsing in the + expression evaluator that caused errors when the operands and corresponding + operators were separated by whitespace. + +f. Fixed a bug that caused `history -p' to add an entry to the history list, + counter to the documentation. (Keeps the history expansions invoked by + emacs-mode command line editing from doing that as well.) + +g. Fixed a bug that could cause a core dump if `cd' is asked to print out a + pathname longer than PATH_MAX characters. + +h. Fixed a bug that caused jobs to be put into the wrong process group under + some circumstances after enabling job control with `set -m'. + +i. `unalias' now returns failure if no alias name arguments are supplied. + +j. Documented the characters not allowed to appear in an alias name. + +k. $* is no longer expanded as if in double quotes when it appears in the + body of a here document, as the SUS seems to require. + +l. The `bashbug' script now uses a directory in $TMPDIR for exclusive + access rather than trying to guess how the underlying OS provides for + secure temporary file creation. + +m. Fixed a few problems with `cd' and `pwd' when asked to operate on pathnames + longer than PATH_MAX characters. + +n. Fixed a memory leak caused when creating multiple local array variables + with identical names. + +o. Fixed a problem with calls to getcwd() so that bash now operates better + when the full pathname to the current directory is longer than PATH_MAX + bytes. + +p. The `trap' builtin now reports an error if a single non-signal argument + is specified. + +q. Fixed a bug that caused `umask' to not work correctly when presented + with a mask of all 0s. + +r. When `getopts' reaches the end of options, OPTARG is unset, as POSIX + appears to specify. + +s. Interactive mode now depends on whether or not stdin and stderr are + connected to a tty; formerly it was stdin and stdout. POSIX requires + this. + +t. Fixed vi-mode completion to work more as POSIX specifies (e.g., doing the + right kind of filename generation). + +2. Changes to Readline + +a. Fixed a problem that could cause readline to refer to freed memory when + moving between history lines while doing searches. + +b. Improvements to the code that expands and displays prompt strings + containing multibyte characters. + +c. Fixed a problem with vi-mode not correctly remembering the numeric argument + to the last `c'hange command for later use with `.'. + +d. Fixed a bug in vi-mode that caused multi-digit count arguments to work + incorrectly. + +e.

Fixed problems with changing characters and changing case at the end of + the line. + +3. New Features in Bash + +a. The `jobs', `kill', and `wait' builtins now accept job control notation + even if job control is not enabled. + +b. The historical behavior of `trap' that allows a missing `action' argument + to cause each specified signal's handling to be reset to its default is + now only supported when `trap' is given a single non-option argument. + +4. New Features in Readline + +a. When listing completions, directories have a `/' appended if the + `mark-directories' option has been enabled. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-3.0-beta1, +and the previous version, bash-3.0-alpha. + +1. Changes to Bash + +a. Fixes to build correctly when arrays are not compiled into the shell. + +b. Fixed command substitution to run any exit trap defined in the command + substitution before returning; the exit trap is not inherited from the + calling shell. + +c.

Fixed processing of octal and hex constants in printf builtin for POSIX.2 + compliance. + +e. Fixed a couple of core dumps in the pattern removal code. + +f. Fixes to the array subrange extraction code to deal better with sparse + arrays. + +g. Parser errors and other errors that result in the shell exiting now cause + the exit trap to be run. + +h. Change the command substitution completion functions to not append any + closing quote, because it would be inserted a closing "`" or ")". + +i. Fix history initialization so assignments to $histchars made in startup + files are honored. + +j. If an exit trap does not contain a call to `exit', the shell now uses + the exit status of the last command executed before the trap as the exit + status of the shell. + +k. The parser now prompts with $PS2 if it reads a newline while parsing a + compound array assignment statement. + +l. When performing a compound array assignment, the parser doesn't treat + words of the form [index]=value as assignments if they're the result of + expansions. + +m. Fixed a bug that caused `return' executed in a trap command to make the + shell think it was still running the trap. + +n. Fixed the value of errno set by the pathname canonicalization functions. + +o. Changed the grammar so that `time' alone on a line times a null command + rather than being a syntax error. + +p. The pattern substitution code no longer performs quote removal on the + pattern before trying to match it, as the pattern removal functions do. + +q. Fixed a bug that could cause core dumps when checking whether a quoted + command name was being completed. + +r. Fixes to the pattern removal and pattern replacement expansions to deal + with multibyte characters better (and faster). + +s. Fix to the substring expansion (${param:off[:len]}) to deal with (possibly + multibyte) characters instead of raw bytes. + +t. Fixed a bug that caused some key bindings set in an inputrc to be ignored + at shell startup. + +u. Fixed a bug that caused unsetting a local variable within a function to + not work correctly. + +v. Fixed a bug that caused invalid variables to be created when using + `read -a'. + +w. Fixed a bug that caused "$@" to expand incorrectly when used as the right + hand side of a parameter expansion such as ${word:="$@"} if the first + character of $IFS was not a space. + +x.

Some changes to the display code to improve display and redisplay of + multibyte characters. + +c. Changes to speed up the multibyte character redisplay code. + +d. Fixed a bug in the vi-mode `E' command that caused it to skip over the + last character of a word if invoked while point was on the word's + next-to-last character. + +e. Fixed a bug that could cause incorrect filename quoting when + case-insensitive completion was enabled and the word being completed + contained backslashes quoting word break characters. + +f. Fixed a bug in redisplay triggered when the prompt string contains + invisible characters. + +g. Fixed some display (and other) bugs encountered in multibyte locales + when a non-ascii character was the last character on a line. + +h. Fixed some display bugs caused by multibyte characters in prompt strings. + +i. Fixed a problem with history expansion caused by non-whitespace characters + used as history word delimiters. + +3. New Features in Bash + +a. printf builtin understands two new escape sequences: \" and \?. + +b. `echo -e' understands two new escape sequences: \" and \?. + +c. The GNU `gettext' package and libintl have been integrated; the shell's + messages can be translated into different languages. + +d. The `\W' prompt expansion now abbreviates $HOME as `~', like `\w'. + +e. The error message printed when bash cannot open a shell script supplied + as argument 1 now includes the name of the shell, to better identify + the error as coming from bash. + +4. New Features in Readline + +a. New application variable, rl_completion_quote_character, set to any + quote character readline finds before it calls the application completion + function. + +b. New application variable, rl_completion_suppress_quote, settable by an + application completion function. If set to non-zero, readline does not + attempt to append a closing quote to a completed word. + +c. New application variable, rl_completion_found_quote, set to a non-zero + value if readline determines that the word to be completed is quoted. + Set before readline calls any application completion function. + +d. New function hook, rl_completion_word_break_hook, called when readline + needs to break a line into words when completion is attempted. Allows + the word break characters to vary based on position in the line. + +e. New bindable command: unix-filename-rubout. Does the same thing as + unix-word-rubout, but adds `/' to the set of word delimiters. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-3.0-alpha, +and the previous version, bash-2.05b-release. + +1. Changes to Bash + +a. Fixes so that the shell will compile without some of the default options + defined. + +b. Fixed an error message that did not pass enough arguments to printf. + +c. Fixed a bug that caused input redirection to a builtin inside a script + being read from standard input to result in the rest of the already- + read and buffered script to be discarded. + +d. Fixed a bug that caused subshell initialization to close the file + descriptor from which the shell was reading a script under certain + circumstances. + +e. Fixed a bug that caused the shell to not advance a string pointer over + a null wide character when doing string operations. + +f. Fixed the internal logout code so that shells that time out waiting for + input (using $TMOUT) run ~/.bash_logout. + +g. Portability and configuration changes for: cygwin, HP/UX, GNU/FreeBSD. + +h. The parser no longer adds implicit double quotes to ((...)) arithmetic + commands. + +i. The ((...)) arithmetic command evaluation code was fixed to not dump core + when the expanded string is null. + +j. The ((...)) arithmetic command evaluation code was fixed to not perform + variable assignments while expanding the expression. + +k. Fixed a bug that caused word splitting to be performed incorrectly when + IFS is set, but null. + +l. Fixed a bug in brace expansion that caused a quoted `$' preceding an + open brace to inhibit brace expansion. + +m. Fixed a bug that caused a leading `-' in the shell's name to cause it to + not be recognized as a restricted shell. + +n. Fixed a bug in the arithmetic evaluation code that could cause longjmps + to an invalid location and result in a core dump. + +o. Fixed a bug in the calculation of how many history lines are new in a + single shell session when reading new history lines from a file with + `history -n'. + +p. Fixed a bug in pathname canonicalization that caused the shell to dump + core when presented with a pathname longer than PATH_MAX. + +q. Fixed the parser so that it doesn't try to compare a char variable to + EOF, which fails when chars are unsigned. + +r. Fixed a bug in the simple command execution code that caused occasional + core dumps. + +s. The shell does a better job of saving any partial parsing state during + operations which cause a command to be executed while a line is being + entered and parsed. + +t. The completion code now splits words more like the expansion code when + $IFS is used to split. + +u. The locale code does a better job of recomputing the various locale + variable values when LC_ALL is unset. + +v. The programmable completion code does a better job of dequoting expanded + word lists before comparing them against the word to be matched. + +w. The shell no longer seg faults if the expanded value of $PS4 is null + and `set -x' is enabled. + +x. Fixed a bug that caused core dumps when a here string expanded to NULL. + +y. The mail checking code now makes sure the mailbox is bigger before + reporting the existence of new mail. + +z. The parser does not try to expand $'...' and $"..." when the appear + within double quotes unless the `extquote' option has been enabled with + `shopt'. For backwards compatibility, it is enabled by default. + +aa. Fixed a bug that caused `for x; do ...' and `select x; do ... to use + $@ instead of "$@" for the implicit list of arguments. + +bb. Fixed a bug that caused a subshell of a restricted shell (e.g., one + spawned to execute a pipeline) to not exit immediately if attempting + to use a command containing a slash. + +cc. Fixed a problem with empty replacements for a pattern that doesn't match + when performing ${param/word/} expansion. + +dd. Word expansions performed while expanding redirections no longer search + a command's temporary environment to expand variable values. + +ee. Improvements to the alias expansion code when expanding subsequent words + because an aliase's value ends with a space. + +ff. `cd -' now prints the current working directory after a successful chdir + even when the shell is not interactive, as the standard requires. + +gg. The shell does a better job of ensuring a child process dies of SIGINT + before resending SIGINT to itself. + +hh. The arithmetic expansion variable assignment code now does the right + thing when assigning to `special' variables like OPTIND. + +ii. When history expansion verification is enabled, the bash readline helper + functions that do history expansion on the current line don't print + the results. + +jj. Fixed bugs with multiple consecutive alias expansion when one of the + expansions ends with a space. + +kk. Fixed a problem in the programmable completion code that could cause core + dumps when trying to initialize a set of possible completions from a + list of variables. + +ll. The \[ and \] escape characters are now ignored when decoding the prompt + string if the shell is started with editing disabled. + +mm. Fixed a bug that could leave extra characters in a string when doing + quoted null character removal. + +nn. Command substitution and other subshell operations no longer reset the + line number (aids the bash debugger). + +oo. Better line number management when executing simple commands, conditional + commands, for commands, and select commands. + +pp. The globbing code now uses malloc, with its better failure properties, + rather than alloca(). + +qq. Fixed a bug that caused expansions like #{a[2]:=value} to create the + appropriate array element instead of a variable named `a[2]'. + +rr. Fixed a bug in the handling of a `?(...)' pattern immediately following + a `*' when extglob is enabled. + +ss. Fixed a bug that caused a `return' invoked in an exit trap when exit is + invoked in a function to misbehave. + +tt. Fixed a bug that caused CTLESC and CTLNUL characters to not be escaped + by the internal shell string quoting functions. + +uu. Fixed a bug that caused quoted null characters in an expanded word list + to be inappropriately assigned to an array variable when using `read -a'. + +vv. Fixed a bug that caused redirections accompanying a null command to persist + in the current shell. + +ww. Fixed a bug that caused the prompt to be printed when the shell was + expanding a multiline alias. + +xx. Fixed a bug that resulted in core dumps when the completion for a command + changed the compspec. + +yy. Fixed a bug that caused evaluation of programmable completions to print + notifications of completed jobs. + +zz. Bash now disables line editing when $EMACS == `t' and $TERM == `dumb' + (which is what emacs shell windows do). + +aaa. In posix mode, `kill -l' causes signal names to be displayed without + a leading `SIG'. + +bbb. Clear error flag on standard output so it doesn't persist across multiple + builtin commands. + +ccc. In posix mode, `alias' displays alias values without the leading `alias', + so the output cannot be used as subsequent input. + +ddd. In posix mode, the `trap' builtin doesn't check whether or not its + first argument is a signal specification and revert the signal handling + to its original disposition if it is. + +eee. Fixed several bugs in the handling of "$*" and "${array[*]}" by the + pattern substitution and removal expansions. + +fff. Fixed several problems with the handling of ${array[@]}, ${array[*]}, + $@, and $* by the indirect variable expansion code. + +ggg. Fixed a bug that did not allow `time' to be aliased. + +hhh. Improved the mail checking code so it won't check (and possibly cause an + NFS file system mount) until MAILPATH or MAIL is given a value -- there + is no default if DEFAULT_MAIL_DIRECTORY is not defined at compile time. + (It is computed by configure, but can be #undef'd in config-bot.h.) + +iii. If the `chkwinsize' option is enabled, the shell checks for window size + changes if a child process exits due to a signal. + +jjj. Removed the attempts to avoid adding a slash at the end of a completed + executable name if there was a directory with the same name in the + current directory. + +kkk. Fixed PATH lookup code so it treats the permission bits separately for + owner, group, and other, rather than checking them all. + +lll. Fixed the locale code to reset the parser's idea of the character class + , which controls how it splits tokens, when the locale changes. + +mmm. The shell now binds its special readline functions and key bindings only + if the user's inputrc file has not already bound them. + +nnn. The shell now reports on processes that dump core due to signals when + invoked as `-c command'. + +2. Changes to Readline + +a.

Fixed the code that adjusts the point to not mishandle null wide + characters. + +f. Fixed a bug in the history expansion `g' modifier that caused it to skip + every other match. + +g. Fixed a bug that caused the prompt to overwrite previous output when the + output doesn't contain a newline and the locale supports multibyte + characters. This same change fixes the problem of readline redisplay + slowing down dramatically as the line gets longer in multibyte locales. + +h. History traversal with arrow keys in vi insertion mode causes the cursor + to be placed at the end of the new line, like in emacs mode. + +i. The locale initialization code does a better job of using the right + precedence and defaulting when checking the appropriate environment + variables. + +j. Fixed the history word tokenizer to handle <( and >( better when used as + part of bash. + +k. The overwrite mode code received several bug fixes to improve undo. + +l. Many speedups to the multibyte character redisplay code. + +m. The callback character reading interface should not hang waiting to read + keyboard input. + +n. Fixed a bug with redoing vi-mode `s' command. + +o. The code that initializes the terminal tracks changes made to the terminal + special characters with stty(1) (or equivalent), so that these changes + are reflected in the readline bindings. New application-callable function + to make it work: rl_tty_unset_default_bindings(). + +p. Fixed a bug that could cause garbage to be inserted in the buffer when + changing character case in vi mode when using a multibyte locale. + +q. Fixed a bug in the redisplay code that caused problems on systems + supporting multibyte characters when moving between history lines when the + new line has more glyphs but fewer bytes. + +r. Undo and redo now work better after exiting vi insertion mode. + +s. Make sure system calls are restarted after a SIGWINCH is received using + SA_RESTART. + +t. Improvements to the code that displays possible completions when using + multibyte characters. + +u. Fixed a problem when parsing nested if statements in inputrc files. + +v. The completer now takes multibyte characters into account when looking for + quoted substrings on which to perform completion. + +w. The history search functions now perform better bounds checking on the + history list. + +3. New Features in Bash + +a. ANSI string expansion now implements the \x{hexdigits} escape. + +b. There is a new loadable `strftime' builtin. + +c. New variable, COMP_WORDBREAKS, which controls the readline completer's + idea of word break characters. + +d. The `type' builtin no longer reports on aliases unless alias expansion + will actually be performed. + +e. HISTCONTROL is now a colon-separated list of values, which permits + more extensibility and backwards compatibility. + +f. HISTCONTROL may now include the `erasedups' option, which causes all lines + matching a line being added to be removed from the history list. + +g. `configure' has a new `--enable-multibyte' argument that permits multibyte + character support to be disabled even on systems that support it. + +h. New variables to support the bash debugger: BASH_ARGC, BASH_ARGV, + BASH_SOURCE, BASH_LINENO, BASH_SUBSHELL, BASH_EXECUTION_STRING, + BASH_COMMAND + +i. FUNCNAME has been changed to support the debugger: it's now an array + variable. + +j. for, case, select, arithmetic commands now keep line number information + for the debugger. + +k. There is a new `RETURN' trap executed when a function or sourced script + returns (not inherited child processes; inherited by command substitution + if function tracing is enabled and the debugger is active). + +l. New invocation option: --debugger. Enables debugging and turns on new + `extdebug' shell option. + +m. New `functrace' and `errtrace' options to `set -o' cause DEBUG and ERR + traps, respectively, to be inherited by shell functions. Equivalent to + `set -T' and `set -E' respectively. The `functrace' option also controls + whether or not the DEBUG trap is inherited by sourced scripts. + +n. The DEBUG trap is run before binding the variable and running the action + list in a `for' command, binding the selection variable and running the + query in a `select' command, and before attempting a match in a `case' + command. + +o. New `--enable-debugger' option to `configure' to compile in the debugger + support code. + +p. `declare -F' now prints out extra line number and source file information + if the `extdebug' option is set. + +q. If `extdebug' is enabled, a non-zero return value from a DEBUG trap causes + the next command to be skipped, and a return value of 2 while in a + function or sourced script forces a `return'. + +r. New `caller' builtin to provide a call stack for the bash debugger. + +s. The DEBUG trap is run just before the first command in a function body is + executed, for the debugger. + +t. `for', `select', and `case' command heads are printed when `set -x' is + enabled. + +u. There is a new {x..y} brace expansion, which is shorthand for {x.x+1, + x+2,...,y}. x and y can be integers or single characters; the sequence + may ascend or descend; the increment is always 1. + +v. New ksh93-like ${!array[@]} expansion, expands to all the keys (indices) + of array. + +w. New `force_fignore' shopt option; if enabled, suffixes specified by + FIGNORE cause words to be ignored when performing word completion even + if they're the only possibilities. + +x. New `gnu_errfmt' shopt option; if enabled, error messages follow the `gnu + style' (filename:lineno:message) format. + +y. New `-o bashdefault' option to complete and compgen; if set, causes the + whole set of bash completions to be performed if the compspec doesn't + result in a match. + +z. New `-o plusdirs' option to complete and compgen; if set, causes directory + name completion to be performed and the results added to the rest of the + possible completions. + +aa. `kill' is available as a builtin even when the shell is built without + job control. + +bb. New HISTTIMEFORMAT variable; value is a format string to pass to + strftime(3). If set and not null, the `history' builtin prints out + timestamp information according to the specified format when displaying + history entries. If set, bash tells the history library to write out + timestamp information when the history file is written. + +cc. The [[ ... ]] command has a new binary `=~' operator that performs + extended regular expression (egrep-like) matching. + +dd. `configure' has a new `--enable-cond-regexp' option (enabled by default) + to enable the =~ operator and regexp matching in [[ ... ]]. + +ee. Subexpressions matched by the =~ operator are placed in the new + BASH_REMATCH array variable. + +ff. New `failglob' option that causes an expansion error when pathname + expansion fails to produce a match. + +gg. New `set -o pipefail' option that causes a pipeline to return a failure + status if any of the processes in the pipeline fail, not just the last + one. + +4. New Features in Readline + +a. History expansion has a new `a' modifier equivalent to the `g' modifier + for compatibility with the BSD csh. + +b. History expansion has a new `G' modifier equivalent to the BSD csh `g' + modifier, which performs a substitution once per word. + +c. All non-incremental search operations may now undo the operation of + replacing the current line with the history line. + +d. The text inserted by an `a' command in vi mode can be reinserted with + `.'. + +e. New bindable variable, `show-all-if-unmodified'. If set, the readline + completer will list possible completions immediately if there is more + than one completion and partial completion cannot be performed. + +f. There is a new application-callable `free_history_entry()' function. + +g. History list entries now contain timestamp information; the history file + functions know how to read and write timestamp information associated + with each entry. + +h. Four new key binding functions have been added: + + rl_bind_key_if_unbound() + rl_bind_key_if_unbound_in_map() + rl_bind_keyseq_if_unbound() + rl_bind_keyseq_if_unbound_in_map() + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05b-release, +and the previous version, bash-2.05b-beta2. + +1. Changes to Bash + +a. Fixed an off-by-one error in the function that translates job + specifications. + +b. Note that we're running under Emacs and disable line editing if + $EMACS == `t'. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05b-beta2, +and the previous version, bash-2.05b-beta1. + +1. Changes to Bash + +a. Fixed the /= and %= arithmetic operators to catch division by zero. + +b. Added putenv, setenv, unsetenv to getenv replacement for completeness. + +c. Fixed a bug that could cause the -O expand_aliases invocation option + to not take effect. + +d. Fixed a problem with process substitution that resulted in incorrect + behavior when the number of process substitutions in an individual + command approached 64. + +2. Changes to Readline + +a. Fixed a problem with backward-char-search when on a system with support + for multibyte characters when running in a locale without any multibyte + characters. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05b-beta1, +and the previous version, bash-2.05b-alpha1. + +1. Changes to Bash + +a. Fixed a problem when parsing a POSIX.2 character class name while + evaluating a bracket expression containing multibyte characters. + +b. Changed the help text for `bind' to make it clear that any command + that may be placed in ~/.inputrc is a valid argument to `bind'. + +c. Added `help' builtin entries for `((', `[[', and arithmetic for. + +d. malloc updated again: + o slightly better overflow and underflow detection by putting the + chunk size at the beginning and end of the chunk and making + sure they match in free/realloc + o partial page allocated to make things page-aligned no longer + completely wasted + o block coalescing now enabled by default + o splitting and coalescing enabled for 32-byte chunks, the most + common size requested + o fixed a problem that resulted in spurious underflow messages and + aborts + o bin sizes are precomputed and stored in an array rather than + being computed at run time + o malloc will return memory blocks back to the system if the block + being freed is at the top of the heap and of sufficient size to + make it worthwhile + o malloc/free/realloc now inline memset instead of calling the + libc function; uses Duff's device for good performance + +e. Check for getservent(); make the service name completion code dependent + on its presence. + +f. Changed the readline callback that executes a command bound to a key + sequence to not save the executed command on the history list and to + save and restore the parsing state. + +g. Changes to lib/sh/snprintf.c: fixed some bugs in the `g' and `G' + floating point format display; implemented the "'" flag character + that turns on thousands' grouping; fixed behavior on systems where + MB_CUR_MAX does not evaluate to a constant. + +h. The `unset' builtin no longer returns a failure status when asked to + unset a previously-unset variable or function. + +i. Changes to the build system to make it easier to cross-compile bash + for different systems. + +j. Added `,' to the characters that are backslash-escaped during filename + completion, to avoid problems with complete-into-braces and RCS filenames + containing commas. + +k. Some changes to the multibyte character support code to avoid many calls + to strlen(). + +l. Bash now correctly honors setting LANG to some value when LC_ALL does not + already have a value. + +m. Fixed a bug that could cause SIGSEGV when processing nested traps with + trap handlers. + +n. The `source/.' builtin now restores the positional parameters when it + returns unless they were changed using the `set' builtin during the file's + execution. + +o. Fixed a bug that caused a syntax error when a command was terminated by + EOF. + +2. New Features in Bash + +a. There is now support for placing the long help text into separate files + installed into ${datadir}/bash. Not enabled by default; can be turned + on with `--enable-separate-helpfiles' option to configure. + +b. All builtins that take operands accept a `--' pseudo-option, except + `echo'. + +c. The `echo' builtin now accepts \0xxx (zero to three octal digits following + the `0') in addition to \xxx (one to three octal digits) for SUSv3/XPG6/ + POSIX.1-2001 compliance. + +3. Changes to Readline + +a. Fixed a small problem in _rl_insert_char with multibyte characters. + +b. Fixes from IBM for line wrapping problems when using multibyte characters. + +c. Fixed a problem which caused the display to be messed up when the last + line of a multi-line prompt (possibly containing invisible characters) + was longer than the screen width. + +d. Fixed a problem with the vi-mode `r' command that ocurred on systems with + support for multibyte characters when running in a locale without any + multibyte characters. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05b-alpha1, +and the previous version, bash-2.05a-release. + +1. Changes to Bash + +a. Some changes to work around inlining differences between compilers. + +b. Added more prototypes for internal shell typedefs, to catch argument + passing errors when using pointers to functions. + +c. The `cd' builtin now fails in posix mode when a valid directory cannot be + constructed from a relative pathname argument and the $PWD using pathname + canonicalization, and the -P option has not been supplied. Previously, + the shell would attempt to use what the user typed, leading to weird + values for $PWD and discrepancies between the value of $PWD and the + actual working directory. + +d. The `cd' builtin now resets $PWD when canonicalization fails but a chdir + to the pathname passed as an argument succeeds (when not in posix mode). + +e. The `fc' builtin has been fixed, as POSIX requires, to use the closest + history position in range when given an out-of-range argument. + +f. The history file loading code was changed to allow lines to be saved in + the history list from the shell startup files. + +g. `history -s args' now works better in compound commands. + +h. The tilde expansion code was fixed to better recognize when it's being + invoked in an assignment context, which enables expansion after `=' + and `:'. + +i. Fixed the command name completion code so a slash is no longer appended + to a single match if there happens to be a directory with that name in + $PWD. + +j. Fixed compound array assignment to no longer perform alias expansion, to + allow reserved words as array members, and to not produce extra output + when the `-v' option had been enabled. + +k. Fixed the programmable completion code to better handle newlines in lists + of possible completions (e.g., `complete -W'). + +l. Removed the reserved words from the `bash-builtins' manual page. + +m. Parser error reporting now attempts to do a better job of identifying the + token in error rather than doing straight textual analysis. + +n. Fixes for Inf/NaN, locales, wide/multibyte characters and zero-length + arguments in the library snprintf(3) replacement. + +o. `read -e' no longer does command name completion on the first word on + the line being read. + +p. `select' now returns failure if the read of the user's selection fails. + +q. Fixed a bug that could cause a core dump when setting $PIPESTATUS. + +r. Fixes to not allocate so many job slots when the shell is running a loop + with job control enabled in a subshell of an interactive shell. + +s. Fixed a bug in the trap code that caused traps to be inherited by + command substitutions in some cases. + +t. Fixed a bug that could cause alias expansion to inappropriately expand + the word following the alias. + +u. Fixed a bug in the `kill' builtin that mishandled negative pid arguments. + +v. The parser is less lenient when parsing assignment statements where the + characters before the `=' don't comprise a valid identifier. + +w. The arithmetic expression evaluation code now honors the setting of the + `-u' option when expanding variable names. + +x. Fixed the arithmetic evaluation code to allow array subscripts to be + assigned (`let b[7]=42') and auto-incremented and auto-decremented + (e.g., b[7]++). + +y. Reimplemented the existing prompt string date and time expansions using + strftime(3), which changed the output of \@ in some locales. + +z. Fixed a bug that could cause a core dump when a special shell variable + (like RANDOM) was converted to an array with a variable assignment. + +aa. Fixed a bug that would reset the handler for a signal the user had + trapped to a function that would exit the shell when setting the exit + trap in a non-interactive shell. + +bb. Changed the execve(2) wrapper code to check whether or not a failing + command is a directory before looking at whether a `#!' interpreter + failed for some reason. + +cc. Fixed a bug in the command printing code so it no longer inserts a `;' + after a newline, which produces a syntax error when reused as input. + +dd. The code that expands $PS4 no longer inherits the `-x' flag. + +ee. The bash-specific completion functions may now take advantage of the + double-TAB and M-? features of the standard readline completion + functions. + +ff. The mail checking code no longer prints a message if the checked file's + size has not increased, even if the access time is less than the modification time. + +gg. Rewrote the variable symbol table code: there is now a stack of + contexts, each possibly including a separate symbol table; there can + be more than one temporary environment supplied to nested invocations + of `./source'; the temporary environments no longer require so much + special-case code; shell functions now handle the temporary environment + and local variables more consistently; function scope exit is faster now + that the entire symbol table does not have to be traversed to dispose of + local variables; it is now easier to push vars from the temporary + environment to the shell's variable table in posix mode; some duplicated + code has been removed. + +hh. Regularized the error message printing code; builtin_error is now called + more consistently, and common error message strings are handled by small + functions. This should make eventual message translation easier. + +ii. Error messages now include the line number in a script when the shell + is not interactive. + +jj. Array subscript expansion now takes place even when the array variable is + unset, so side effects will take place. + +kk. Fixed a bug in the SICGHLD child-reaping code so that it won't find + jobs already marked as terminated if the OS reuses pids quickly enough. + +ll. Fixed a bug that could cause a signal to not interrupt the `wait' + builtin while it was waiting for a background process to terminate. + +mm. A couple of changes to make it easier for multiple shells to share history + files using `history -n', `history -r', and `history -w'. + +nn. The `getopts' builtin always increments OPTIND to point to the next + option to be handled when an option is returned, whether it's valid + or not, as POSIX 1003.x-2001 requires. + +oo. Changed some parts of the expansion code to avoid allocating and + immediately freeing memory without using the results for anything. + +pp. The shell now keeps track of $IFS internally, updating its internal map + each time the variable is assigned a new value (or at local scope exit). + This saves thousands of hash lookups for IFS, which, while individually + cheap, add up. + +qq. Rewrote the hash table code: searching and insertion are much faster now, + and it uses a better string hashing function; augmented the function + interface to simplify other parts of the code and remove duplicated code + +rr. The shell now uses a simple, generic `object cache' for allocating and + caching words and word lists, which were the major users of + malloc/free. + +ss. Fixed the assignment statement parsing code to allow whitespace and + newlines in subscripts when performing array element assignment. + +tt. The shell now issues many fewer calls to sigprocmask and other signal + masking system calls. + +uu. Fixed the `test' and conditional command file comparison operators to + work right when one file has a non-positive timestamp and the other + does not exist. + +vv. Fixed some cases where the special characters '\001' and '\177' in the + values of variables or positional parameters caused incorrect expansion + results. + +2. Changes to Readline + +a. Fixed output of comment-begin character when listing variable values. + +b. Added some default key bindings for common escape sequences produced by + HOME and END keys. + +c. Fixed the mark handling code to be more emacs-compatible. + +d. A bug was fixed in the code that prints possible completions to keep it + from printing empty strings in certain circumstances. + +e. Change the key sequence printing code to print ESC as M\- if ESC is a + meta-prefix character -- it's easier for users to understand than \e. + +f. Fixed unstifle_history() to return values that match the documentation. + +g. Fixed the event loop (rl_event_hook) to handle the case where the input + file descriptor is invalidated. + +h. Fixed the prompt display code to work better when the application has a + custom redisplay function. + +i. Changes to make reading and writing the history file a little faster, and + to cope with huge history files without calling abort(3) from xmalloc. + +j. The vi-mode `S' and `s' commands are now undone correctly. + +3. New Features in Bash + +a. If set, TMOUT is the default timeout for the `read' builtin. + +b. `type' has two new options: `-f' suppresses shell function lookup, and + `-P' forces a $PATH search. + +c. New code to handle multibyte characters. + +d. `select' was changed to be more ksh-compatible, in that the menu is + reprinted each time through the loop only if REPLY is set to NULL. + The previous behavior is available as a compile-time option. + +e. `complete -d' and `complete -o dirnames' now force a slash to be + appended to names which are symlinks to directories. + +f. There is now a bindable edit-and-execute-command readline command, + like the vi-mode `v' command, bound to C-xC-e in emacs mode. + +g. Added support for ksh93-like [:word:] character class in pattern matching. + +h. The $'...' quoting construct now expands \cX to Control-X. + +i. A new \D{...} prompt expansion; passes the `...' to strftime and inserts + the result into the expanded prompt. + +j. The shell now performs arithmetic in the largest integer size the + machine supports (intmax_t), instead of long. + +k. If a numeric argument is supplied to one of the bash globbing completion + functions, a `*' is appended to the word before expansion is attempted. + +l. The bash globbing completion functions now allow completions to be listed + with double tabs or if `show-all-if-ambiguous' is set. + +m. New `-o nospace' option for `complete' and `compgen' builtins; suppresses + readline's appending a space to the completed word. + +n. New `here-string' redirection operator: <<< word. + +o. When displaying variables, function attributes and definitions are shown + separately, allowing them to be re-used as input (attempting to re-use + the old output would result in syntax errors). + +p. There is a new configuration option `--enable-mem-scramble', controls + bash malloc behavior of writing garbage characters into memory at + allocation and free time. + +q. The `complete' and `compgen' builtins now have a new `-s/-A service' + option to complete on names from /etc/services. + +r. `read' has a new `-u fd' option to read from a specified file descriptor. + +s. Fix the completion code so that expansion errors in a directory name + don't cause a longjmp back to the command loop. + +t. Fixed word completion inside command substitution to work a little more + intuitively. + +u. The `printf' %q format specifier now uses $'...' quoting to print the + argument if it contains non-printing characters. + +v. The `declare' and `typeset' builtins have a new `-t' option. When applied + to functions, it causes the DEBUG trap to be inherited by the named + function. Currently has no effect on variables. + +w. The DEBUG trap is now run *before* simple commands, ((...)) commands, + [[...]] conditional commands, and for ((...)) loops. + +x. The expansion of $LINENO inside a shell function is only relative to the + function start if the shell is interactive -- if the shell is running a + script, $LINENO expands to the line number in the script. This is as + POSIX-2001 requires. + +y. The bash debugger in examples/bashdb has been modified to work with the + new DEBUG trap semantics, the command set has been made more gdb-like, + and the changes to $LINENO make debugging functions work better. Code + from Gary Vaughan. + +z. New [n]<&word- and [n]>&word- redirections from ksh93 -- move fds (dup + and close). + +aa. There is a new `-l' invocation option, equivalent to `--login'. + +bb. The `hash' builtin has a new `-l' option to list contents in a reusable + format, and a `-d' option to remove a name from the hash table. + +4. New Features in Readline + +a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both + be bound to readline functions. Now the arrow keys may be used in vi + insert mode. + +b. When listing completions, and the number of lines displayed is more than + the screen length, readline uses an internal pager to display the results. + This is controlled by the `page-completions' variable (default on). + +c. New code to handle editing and displaying multibyte characters. + +d. The behavior introduced in bash-2.05a of deciding whether or not to + append a slash to a completed name that is a symlink to a directory has + been made optional, controlled by the `mark-symlinked-directories' + variable (default is the 2.05a behavior). + +e. The `insert-comment' command now acts as a toggle if given a numeric + argument: if the first characters on the line don't specify a + comment, insert one; if they do, delete the comment text + +f. New application-settable completion variable: + rl_completion_mark_symlink_dirs, allows an application's completion + function to temporarily override the user's preference for appending + slashes to names which are symlinks to directories. + +g. New function available to application completion functions: + rl_completion_mode, to tell how the completion function was invoked + and decide which argument to supply to rl_complete_internal (to list + completions, etc.). + +h. Readline now has an overwrite mode, toggled by the `overwrite-mode' + bindable command, which could be bound to `Insert'. + +i. New application-settable completion variable: + rl_completion_suppress_append, inhibits appending of + rl_completion_append_character to completed words. + +j. New key bindings when reading an incremental search string: ^W yanks + the currently-matched word out of the current line into the search + string; ^Y yanks the rest of the current line into the search string, + DEL or ^H deletes characters from the search string. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05a-release, +and the previous version, bash-2.05a-rc1. + +1. Changes to Bash + +a. Fixed the `printf' builtin so that the variable name supplied as an + argument to a %n conversion must be a valid shell identifier. + +b. Improved the random number generator slightly. + +c. Changes to configuration to not put -I/usr/include into $CFLAGS, since + it messes up some includes. + +d. Corrected description of POSIXLY_CORRECT in man page and info manual. + +e. Fixed a couple of cases of incorrect function prototypes that sneaked + through and caused compilation problems. + +f. A few changes to avoid potential core dumps in the programmable completion + code. + +g. Fixed a configure problem that could cause a non-existent file to show + up in LIBOBJS. + +h. Fixed a configure problem that could cause siglist.o to not be built when + required. + +i. Changes to the strtoimax and strtoumax replacement functions to work + around buggy compilers. + +j. Fixed a problem with the snprintf replacement function that could + potentially cause a core dump. + +2. Changes to Readline + +a. Fixed a locale-specific problem in the vi-mode `goto mark' command. + +b. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause + include file problems. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05a-rc1, +and the previous version, bash-2.05a-beta1. + +1. Changes to Bash + +a. Fixed the snprintf replacement to correctly implement the `alternate form' + of the %g and %G conversions. + +b. Fixed snprintf to correctly handle the optional precision with the %g and + %G conversions. + +c. Fixed the arithmetic evaluation code to correct the values of `@' and `_' + when translating base-64 constants (they were backwards). + +d. New library functions for formatting long and long long ints. + +e. Fixed a few places where negative array subscripts could have occurred, + mostly as the result of systems using signed characters. + +f. Fixed a few places that assumed a pid_t was no wider than an int. + +g. Fixed the `maildir' mail checking code to work on systems where a + `struct stat' doesn't include an `st_blocks' member. + +h. Fixed snprintf to make `unsigned long long' conversion formats (%llu) + work better. + +i. Fixed snprintf to not print a sign when asked to do an unsigned conversion. + +j. Made configure changes to avoid compiling empty source files in lib/sh. + +k. New replacement functions (if necessary) for strtoull, strtoll, strtoimax, + strtoumax. + +l. The `printf' builtin now handles the `ll' and `j' length modifiers + directly, since they can affect the type and width of the argument + passed to printf(3). + +m. Renamed a number of the bash-specific autoconf macros in aclocal.m4 to + have more sytematic naming, with accompanying changes to configure.in. + +n. Fixed snprintf to handle long doubles and the %a/%A conversions by + falling back to sprintf, as long as sprintf supports them. + +o. Fixed return value from vsnprintf/snprintf to be the number of characters + that would have been printed, even if that number exceeds the buffer + size passed as an argument. + +p. Bash no longer attempts to define its own versions of some ctype macros + if they are implemented as functions in libc but not as macros in + . + +q. Changed the variable printing code (used by `set', `export', etc.) to + not use the $'...' syntax when in posix mode, since that caused + interoperability problems with other shells (most notably with autoconf). + When not in posix mode, it uses $'...' if the string to be printed + contains non-printing characters and regular single quotes otherwise. + +r. snprintf now recognizes the %F conversion. + +s. Fixed a bug that could cause the wrong status to be returned by a shell + function when the shell is compiled without job control and a null + command containing a command substutition was executed in the function. + +t. When in posix mode, the default value for MAILCHECK is 600. + +u. Bash only initializes FUNCNAME, GROUPS, and DIRSTACK as special variables + if they're not in the initial environment. + +v. If SECONDS appears in the initial environment with a valid integer value, + bash uses that as the starting value, as if an assignment had been + performed. + +w. Bash no longer auto-exports HOME, PATH, SHELL, or TERM, even though it + gives them default values if they don't appear in the initial environment. + +x. Bash no longer auto-exports HOSTNAME, HOSTTYPE, MACHTYPE, or OSTYPE, + even if it assigns them default values. + +y. Bash no longer removes the export attribute from SSH_CLIENT or SSH2_CLIENT + if they appear in the initial environment. + +z. Bash no longer attempts to discover if it's being run by sshd in order to + run the startup files. If the SSH_SOURCE_BASHRC is uncommented in + config-top.h it will attempt to do so as previously, but that's commented + out in the distributed version. + +aa. Fixed a typo in the code that tests for LC_NUMERIC. + +bb. The POSIXLY_CORRECT shell variable and its effects are now documented. + +cc. Some changes to several of the support shell scripts included in the + definitions to try to avoid race conditions and attacks. + +dd. Several changes to avoid warnings from `gcc -Wall'. + +ee. Fixed a problem with the `unset' builtin that could cause incorrect + results if asked to unset a variable and an array subscript in the + same command. + +ff. A few changes to the shell's temporary file creation code to avoid + potential file descriptor leaks and to prefer the system's idea of + the temporary directory to use. + +gg. Fixes to build with the C alloca in lib/malloc/alloca.c if the system + requires it but the shell has been configured --without-bash-malloc. + +hh. Updated the documentation to note that only interactive shells resend + SIGHUP to all jobs before exiting. + +ii. Fixes to only pass unquoted tilde words to tilde_expand, rather than + rely on tilde_expand or getpwnam(3) to handle the quotes (MacOS 10.x + will remove backslashes in any login name passed to getpwnam(3)). + +jj. Small change from Paul Eggert to make LINENO right in commands run with + `bash -c'. + +2. New Features in Bash + +a. The `printf' builtin now handles the %a and %A conversions if they're + implemented by printf(3). + +b. The `printf' builtin now handles the %F conversion (just about like %f). + +c. The `printf' builtin now handles the %n conversion like printf(3). The + corresponding argument is the name of a shell variable to which the + value is assigned. + +3. Changes to Readline + +a. Fixed a few places where negative array subscripts could have occurred. + +b. Fixed the vi-mode code to use a better method to determine the bounds of + the array used to hold the marks. + +c. Fixed the defines in chardefs.h to work better when chars are signed. + +d. Fixed configure.in to use the new names for bash autoconf macros. + +e. Readline no longer attempts to define its own versions of some ctype + macros if they are implemented as functions in libc but not as macros in + . + +f. Fixed a problem where rl_backward could possibly set point to before + the beginning of the line. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05a-beta1, +and the previous version, bash-2.05a-alpha1. + +1. Changes to Bash + +a. Fixed a bug in the evalution of arithmetic `for' statements when the + expanded expression is NULL. + +b. Fixed an unassigned variable problem in the redirection printing code. + +c. Added more prototypes to extern function declarations in the header + files and to static function declarations in C source files. + +d. Make sure called functions have a prototype in scope, to get the arguments + and return values right instead of casting. Removed extern function + declarations from C source files that were already included in header + files. + +e. Changed some function arguments to use function typedefs in general.h so + the prototypes can be checked. The only use of Function and VFunction + now is for unwind-protects. + +f. More const changes to function arguments and appropriate variables. + +g. Changed the mail checking support to handle `maildir'-style mail + directories. + +h. Augmented the bash malloc to pass in the file and line number information + for each malloc, realloc, and free. This should result in better error + messages. + +i. The `old' gnu malloc is no longer a configuration option. + +j. Augmented the bash malloc with optional tracing and registering allocated + and freed memory. + +k. Prompt string decoding now saves and restores the value of $? when it + expands the prompt string, so command substitutions don't change $?. + +i. Array indices are now `long', since shell arithmetic is performed as long, + and the internal arrayind_t type is used consistently. + +j. Some more `unsigned char *' fixes from Paul Eggert. + +k. Fixed a bad call to builtin_error that could cause core dumps when making + local variables. + +l. `return' may no longer be used to terminate a `select' command, for + compatibility with ksh. + +m. Changed code that reads octal numbers to do a better job of detecting + overflows. + +n. The time formatting code no longer uses absolute indices into a buffer, + because the buffer size changes depending on the size of a `time_t'. + +o. `umask' now prints four digits when printing in octal mode, for + compatibility with other shells. + +p. Lots of changes to the `printf' builtin from Paul Eggert: it handles `L' + formats and long doubles better, and internal functions have been + simpified where appropriate. + +q. Some `time_t' fixes for machines were a time_t is bigger than a long. + +r. Replaced some bash-specific autoconf macros with standard equivalents. + +s. Improvmed the code that constructs temporary filenames to make the + generated names a bit more random. + +t. Added code that checks for ascii before calling any of the is* ctype + functions. + +u. Changed some places where a `char' was used as an array subscript to use + `unsigned char', since a `char' can be negative if it's signed by default. + +v. Lots of changes to the `ulimit' builtin from Paul Eggert to add support + for the new POSIX-200x RLIM_SAVED_CUR and RLIM_SAVED_MAX values and + simplify the code. + +w. `ulimit' now prints the description of a resource in any error message + relating to fetching or setting that resource's limits. + +x. The `snprintf' replacement now computes maximum values at compile + time rather than using huge constants for things like long long. + +y. Interactive shells now ignore `set -n'. + +z. Changed the malloc bookkeeping information so that it's now 8 bytes + instead of 12 on most 32-bit machines (saving 4 bytes per allocation), + restoring 8-byte alignment. + +aa. The malloc error reporting code now attempts to print the file and line + number of the call that caused the error. + +bb. Changed the redirection error reporting code to catch EBADF errors and + report the file descriptor number rather than the file being redirected + to or from (e.g., things like `exec 4242&word' redirection now works in POSIX mode as it does by default, + since POSIX.2 leaves it unspecified. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05-beta2, +and the previous version, bash-2.05-beta1. + +1. Changes to Bash + +a. Fixed a bug in the arithmetic evaluation code so that a^=b is supported. + +b. Fixed startup so posixly_correct is retained across subshells begun to + execute scripts without a leading `#!'. + +c. Fixed a bug that caused $(< file) to not work in a (...) subshell. + +d. Added config support for Linux running on the IBM S390. + +e. Fixed a bug that caused bash to get its input pointer out of sync when + reading commands through a pipe and running a command with standard + input redirected from a file. + +f. Made a change so that command completion now makes about half as many + stat(2) calls when searching the $PATH. + +g. Fixed a bug that caused variable assignments preceding `return' to not + be propagated to the shell environment in POSIX mode. + +h. Fixed a bug with ${parameter[:]?word} -- tilde expansion was not performed + on `word'. + +i. In POSIX mode, `break' and `continue' do not complain and return success + if called when the shell is not executing a loop. + +j. Fixed `bash -o posix' to work the same as `bash --posix'. + +k. Fixed a bug where variable assignments preceding `eval' or `source/.' + would not show up in the environment exported to subshells run by the + commands. + +l. In POSIX mode, shells started to execute command substitutions inherit + the value of the `-e' option from their parent shell. + +m. In POSIX mode, aliases are expanded even in non-interactive shells. + +n. Changed some of the job control messages to display the text required by + POSIX.2 when the shell is in POSIX mode. + +o. Fixed a bug in `test' that caused it to occasionally return incorrect + results when non-numeric arguments were supplied to `-t'. + +2. Changes to Readline + +a. Some changes were made to avoid gcc warnings with -Wall. + +b. rl_get_keymap_by_name now finds keymaps case-insensitively, so + `set keymap EMACS' works. + +c. The history file writing and truncation functions now return a useful + status on error. + +d. Fixed a bug that could cause applications to dereference a NULL pointer + if a NULL second argument was passed to history_expand(). + +3. New Features in Bash + +a. doc/readline.3 has been moved to the readline distribution. + +4. New Features in Readline + +a. New function, rl_get_screen_size (int *rows, int *columns), returns + readline's idea of the screen dimensions. + +b. The timeout in rl_gather_tyi (readline keyboard input polling function) + is now settable via a function (rl_set_keyboard_input_timeout()). + +c. Renamed the max_input_history variable to history_max_entries; the old + variable is maintained for backwards compatibility. + +d. The list of characters that separate words for the history tokenizer is + now settable with a variable: history_word_delimiters. The default + value is as before. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05-beta1, +and the previous version, bash-2.05-alpha1. + +1. Changes to Bash + +a. Changes to allow shared library and object building on the GNU Hurd. + +b. Fixes to the way exported functions are placed into the environment and + cached. + +c. The globbing library once again respects locales when processing ranges + in bracket expressions while doing pattern matching. + +d. System-specific configuration changes for: Tru 64, Interix + +e. Bashbug now uses /usr/bin/editor as one of the editing alternatives, and + will use mktemp(1) or tempfile(1), if present, for temporary file creation. + +f. Bash no longer performs a binary file check on a script argument that's + really a tty (like /dev/fd/0 or /dev/stdin). + +g. Fixed a bug in the execution of shell scripts that caused the effects of + $BASH_ENV to be undone in some cases. + +h. Fixed several bugs that made `bash [-i] /dev/stdin' not work correctly. + +i. Several changes to the job control code to avoid some signal state + manipulation. + +j. The Bash malloc no longer blocks signals as often, which should make it + faster. + +k. Fixed a parsing bug that did not allow backslash to escape a single quote + inside a $'...' construct. + +l. Fixed a bug that caused things like ${var:=$'value'} to be parsed + incorrectly. This showed up in newer versions of autoconf. + +m. Fixed a bug in the bash-specific readline initialization that caused + key bindings to bash-specific function names appearing in .inputrc to + not be honored. + +n. Bash now sets the file descriptor it uses to save the file descriptor + opened on a shell script to close on exec. + +o. Fixed a bug in the prompt string decoding that caused it to misbehave + when presented an octal sequence of fewer than three characters. + +p. Fixed the `test' builtin to return an error if `[' is supplied a single + argument that is not `]'. + +q. Fixed a bug that caused subshells started to run executable shell scripts + without a leading `#!' to incorrectly inherit an argument list preceding + a shell builtin (like such a script called from a script sourced with `.', + where there were variable assignments preceding the `.' command) + +r. Fixed a bug that caused changes to variables supplied in an assignment + statement preceding a shell builtin to not be honored (like a script + run with `.'). + +s. HOSTTYPE, OSTYPE, and MACHTYPE are set only if they do not have values + when the shell is started. + +t. Fixed a bug that caused SIGINT to kill shell scripts after the script + called `wait'. + +u. The `fc' builtin now tries to create its temporary files in the directory + named by $TMPDIR. + +v. Bash no longer calls any Readline functions or uses any Readline variables + not declared in readline.h. + +w. Fixed a bug that caused some substitutions involving $@ to not be split + correctly, especially expansions of the form ${paramterOPword}. + +x. SSH2_CLIENT is now treated like SSH_CLIENT and not auto-exported if it + appears in the initial environment. + +y. Fixed a couple of problems with shell scripts without a leading `#!' + being executed out of shell functions that could cause core dumps if + such a script attempted to execute `return'. + +z. Fixed a problem with the `-nt' and `-ot' binary operators for the + `test/[' builtin and the `[[' conditional command that caused wrong + return values if one of the file arguments did not exist. + +aa. Fixed a bug that caused non-interactive shells which had previously + executed `shopt -s expand_aliases' to fail to expand aliases in a + command like `(command) &'. + +2. Changes to Readline + +a. Changes to make most (but not yet all -- there is still crlf()) of the + exported readline functions declared in readline.h have an rl_ prefix. + +b. More `const' changes in function arguments, mostly for completion + functions. + +c. Fixed a bug in rl_forward that could cause the point to be set to before + the beginning of the line in vi mode. + +d. Fixed a bug in the callback read-char interface to make it work when a + readline function pushes some input onto the input stream with + rl_execute_next (like the incremental search functions). + +e. Fixed a file descriptor leak in the history file manipulation code that + was tripped when attempting to truncate a non-regular file (like + /dev/null). + +f. Some existing variables are now documented and part of the public + interface (declared in readline.h): rl_explict_arg, rl_numeric_arg, + rl_editing_mode, rl_last_func. + +g. Renamed rltty_set_default_bindings to rl_tty_set_default_bindings and + crlf to rl_crlf, so there are no public functions declared in readline.h + without an `rl_' prefix. The old functions still exist for backwards + compatibility. + +3. New Features in Bash + +a. A new loadable builtin, realpath, which canonicalizes and expands symlinks + in pathname arguments. + +b. When `set' is called without options, it prints function defintions in a + way that allows them to be reused as input. This affects `declare' and + `declare -p' as well. + +4. New Features in Readline + +a. New application-callable function rl_set_prompt(const char *prompt): + expands its prompt string argument and sets rl_prompt to the result. + +b. New application-callable function rl_set_screen_size(int rows, int cols): + public method for applications to set readline's idea of the screen + dimensions. + +c. The history example program (examples/histexamp.c) is now built as one + of the examples. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.05-alpha1, +and the previous version, bash-2.04-release. + +1. Changes to Bash + +a. A fix was made to allow newlines in compond array assignments. + +b. configure now checks for real-time signals with unusable values. + +c. Interactive shells no longer exit if a substitution fails because of an + unset variable within a sourced file. + +d. Fixed a problem with incorrect matching of extended glob patterns when + doing pattern substitution. + +e. `{' is now quoted by the completion code when it appears in a filename. + +f. Fixed an error in pattern matching that caused the matcher to not + correctly skip the rest of a bracket expression after a character + matched. + +g. Fixed a bug in the IFS word splitting code to make a non-whitespace IFS + character preceded by IFS whitespace part of the current delimiter rather + than generating a separate field. + +h. The {!prefix@} expansion now generates separate words, analogous to $@, + when double-quoted. + +i. Command substitution now ignores NUL bytes in the command output, and the + parser ignores them on input. + +j. A fix was made to the job control code to prevent hanging processes when + the shell thinks background processes are running but the kernel returns + -1/ECHILD from waitpid(). + +k. `pwd' now prints an error message if the write fails when displaying the + current directory. + +l. When in POSIX mode, the shell prints trap dispostions without a leading + `SIG' in the signal specification. + +m. Fixed a parser bug that caused the current command's line count to be + messed up by a compound array assignment. + +n. Fixed a bug in the unwind-protect code that caused bad behavior on machines + where ints and pointers are not the same size. + +o. System-specific configure changes for: MacOS X. + +p. Changes for Cygwin to translate \r\n and \r to \n and to set file + descriptors used for reading input to text mode in various places. + +q. Fixed a bug that caused `!' to occasionally not be honored when in + a (...) subshell. + +r. Bash no longer assumes that getcwd() will return any useful error message + in the buffer passed as an argument if the call fails. + +s. The `source', `.', and `fc' builtins no longer check whether a file is + binary before reading commands from it. + +t. Subshells no longer turn off job control when they exit, since that + sometimes resulted in the terminal being reset to the wrong process + group. + +u. The history code no longer tries to save the second and subsequent lines + of a multi-line command if the first line was not saved. + +v. The history saving code now does a better job of saving blank lines in a + multi-line command. + +w. Removed a `feature' that made `ulimit' silently translate `unlimited' to + the current hard limit, which obscured some kernel error returns. + +x. Fixed the grammar so that `}' is recognized as a reserved word after + another reserved word, rather than requiring a `;' or newline. This + means that constructs like + + { { echo a b c ; } } + + work as expected. + +y. Conditional commands ([[...]]) now perform tilde expansion on their + arguments. + +z. Noted in the documentation that `set -a' will cause functions to be + exported if they are defined after `set -a' is executed. + +aa. When an interactive login shell starts, if $PWD and $HOME refer to the + same directory but are not the same string, $PWD is set to $HOME. + +bb. Fixed `printf' to handle invalid floating point numbers better. + +cc. Temporary files are now created with random filenames, to improve security. + +dd. The readline initialization code now binds the custom bash functions and + key bindings after the readline defaults are set up. + +ee. Fixed the `source' builtin to no longer overwrite a shell function's + argument list, even if the sourced file changes the positional parameters. + +ff. A bug fix was made in the expansion of `$*' in contexts where it should + not be split, like assignment statements. + +gg. Fixed a bug in the parameter substring expansion to handle conditional + arithmetic expressions ( exp ? val1 : val2 ) without cutting the expression + off at the wrong `:'. + +hh. The `<>' redirection is no longer subject to the current setting of + `noclobber', as POSIX.2 specifies. + +ii. Fixed a bug in the conditional command parsing code that caused expressions + in parentheses to occasionally be parsed incorrectly. + +jj. Fixed a bug in the ((...)) arithmetic command to allow do...done or + {...} to follow the )) without an intervening list terminator. + +kk. `printf' now treats `\E' the same as `\e' when performing backslash escape + expansion for the `%b' format specifier. + +ll. When in POSIX mode, the shell no longer searches the current directory for + a file to be sourced with `.' or `source' if `.' is not in $PATH. + +mm. Interactive comments are no longer turned off when POSIX mode is disabled. + +nn. The UID, EUID, HOSTNAME variables are not set if they are in the shell's + environment when it starts up. + +oo. Fixed a bug in the `command' builtin so the effect of a command like + `command exec 4(...) + expansions to defer removal until after any current shell function has + finished executing. + +f. Fixed a bug in `select' which caused it to not handle the `continue' + builtin correctly. + +g. Autoconf tests added for cygwin32 and mingw32. + +2. New Features in Bash + +a. The `--with-bash-malloc' configure option replaces `--with-gnu-malloc' + (which is still there for backwards compatibility). + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.04-beta1, +and the previous version, bash-2.04-alpha1. + +1. Changes to Bash + +a. Fixed a bug in the programmable completion code that occurred when + trying to complete command lines containing a `;' or `@'. + +b. The file descriptor from which the shell is reading a script is now + moved to a file descriptor above the user-addressible range. + +c. Changes to `printf' so that it can handle integers beginning with 0 + or 0x as octal and hex, respectively. + +d. Fixes to the programmable completion code so it handles nonsense like + `compgen -C xyz' gracefully. + +e. The shell no longer modifies the signal handler for SIGPROF, allowing + profiling again on certain systems. + +f. The shell checks for a new window size, if the user has requested it, + after a process exits due to a signal. + +g. Fixed a bug with variables with null values in a program's temporary + environment and the bash getenv() replacement. + +h. `declare' and the other builtins that take variable assignments as + arguments now honor `set -a' and mark modified variables for export. + +i. Some changes were made for --dump-po-strings mode when writing strings + with embedded newlines. + +j. The code that caches export strings from the initial environment now + duplicates the string rather than just pointing into the environment. + +k. The filename completion quoting code now uses single quotes by default + if the filename being completed contains newlines, since \ + has a special meaning to the parser. + +l. Bash now uses typedefs bits32_t and u_bits32_t instead of int32_t and + u_int32_t, respectively to avoid conflicts on certain Unix versions. + +m. Configuration changes were made for: Rhapsody, Mac OS, FreeBSD-3.x. + +n. Fixed a problem with hostname-to-ip-address translation in the + /dev/(tcp|udp)/hostname/port redirection code. + +o. The texinfo manual has been reorganized slightly. + +p. Filename generation (globbing) range comparisons in bracket expressions + no longer use strcoll(3) even if it is available, since it has unwanted + effects in certain locales. + +q.

The ksh-93 ${!prefix*} expansion, which expands to the names of all + shell variables whose names start with prefix, has been implemented. + +l. There is a new dynamic variable, FUNCNAME, which expands to the name of + a currently-executing function. Assignments to FUNCNAME have no effect. + +m.

Changes to Bash + +a. OS-specific configuration changes for: BSD/OS 3.x, Minix 2.x, + Solaris 2.6, SINIX SVR4. + +b. Changes were made to the generated `info' files so that `install-info' + works correctly. + +c. PWD is now auto-exported. + +d. A fix was made to the pipeline code to make sure that the shell forks + to execute simple commands consisting solely of assignment statements. + +e. Changes to the test suite for systems with 14-character filenames. + +f. The default sizes of some internal hash tables have been made smaller + to reduce the shell's memory footprint. + +g. The `((...))' arithmetic command is now executed directly instead of + being translated into `let "..."'. + +h. Fixes were made to the expansion code so that "$*", "$@", "${array[@]}", + and "${array[@]}" expand correctly when IFS does not contain a space + character, is unset, or is set to NULL. + +i. The indirect expansion code (${!var}) was changed so that the only + valid values of `var' are variable names, positional parameters, `#', + `@', and `*'. + +j. An arithmetic expression error in a $((...)) expansion now causes a + non-interactive shell running in posix mode to exit. + +k. Compound array assignment now splits the words within the parentheses + on shell metacharacters like the parser would before expansing them + and performing the assignment. This is for compatibility with ksh-93. + +l. The internal shell backslash-quoting code (used in the output of `set' + and completion) now quotes tildes if they appear at the start of the + string or after a `=' or `:'. + +m. A couple of bugs with `shopt -o' were fixed. + +n. `bash +o' now displays the same output as `set +o' before starting an + interactive shell. + +o. A bug that caused command substitution and the `eval' builtin to + occasionally free memory twice when an error was encountered was fixed. + +p. The filename globbing code no longer requires read permission for a + directory when the filename to be matched does not contain any globbing + characters, as POSIX.2 specifies. + +q. A bug was fixed so that the job containing the last asynchronous + process is not removed from the job table until a `wait' is executed + for that process or another asynchronous process is started. This + satisfies a POSIX.2 requirement. + +r. A `select' bug was fixed so that a non-numeric user response is treated + the same as a numeric response that is out of range. + +s. The shell no longer parses the value of SHELLOPTS from the environment + if it is restricted, running setuid, or running in `privileged mode'. + +t. Fixes were made to enable large file support on systems such as + Solaris 2.6, where the size of a file may be larger than can be held + in an `int'. + +u. The filename hashing code was fixed to not add `./' to the beginning of + filenames which already begin with `./'. + +v. The configure script was changed so that the GNU termcap library is not + compiled in if `prefer-curses' has been specified. + +w. HISTCONTROL and HISTIGNORE are no longer applied to the second and + subsequent lines of a multi-line command. + +x. A fix was made to `disown' so that it does a better job of catching + out-of-range jobs. + +y. Non-interactive shells no longer report the status of processes terminated + due to SIGINT, even if the standard output is a terminal. + +z. A bug that caused the output of `jobs' to have extra carriage returns + was fixed. + +aa. A bug that caused PIPESTATUS to not be set when builtins or shell + functions were executed in the foreground was fixed. + +bb. Bash now attempts to detect when it is being run by sshd, and treats + that case identically to being run by rshd. + +cc. A bug that caused `set -a' to export SHELLOPTS when one of the shell + options was changed was fixed. + +dd. The `kill' builtin now disallows empty or missing process id arguments + instead of treating them as identical to `0', which means the current + process. + +ee. `var=value declare -x var' now behaves identically to + `var=value export var'. Similarly for `var=value declare -r var' and + `var=value readonly var'. + +ff. A few memory leaks were fixed. + +gg. `alias' and `unalias' now print error messages when passed an argument + that is not an alias for printing or deletion, even when the shell is + not interactive, as POSIX.2 specifies. + +hh. `alias' and `alias -p' now return a status of 0 when no aliases are + defined, as POSIX.2 specifes. + +ii. `cd -' now prints the pathname of the new working directory if the shell + is interactive. + +jj. A fix was made so that the code that binds $PWD now copes with getcwd() + returning NULL. + +kk. `unset' now checks whether or not a function name it's trying to unset + is a valid shell identifier only when the shell is running in posix mode. + +ll. A change was made to the code that generates filenames for here documents + to make them less prone to name collisions. + +mm. The parser was changed so that `time' is recognized as a reserved word + only at the beginning of a pipeline. + +nn. The pathname canonicalization code was changed so that `//' is converted + into `/', but all other pathnames beginning with `//' are left alone, as + POSIX.2 specifies. + +oo. The `logout' builtin will no longer exit a non-interactive non-login + shell. + +2. Changes to Readline + +a. Fixed a problem in the readline test program rltest.c that caused a core + dump. + +b. The code that handles parser directives in inputrc files now displays + more error messages. + +c. The history expansion code was fixed so that the appearance of the + history comment character at the beginning of a word inhibits history + expansion for that word and the rest of the input line. + +3. New Features in Bash + +a. A new version of malloc, based on the older GNU malloc, that has many + changes, is more page-based, is more conservative with memory usage, + and does not `orphan' large blocks when they are freed. + +b. A new version of gmalloc, based on the old GLIBC malloc, with many + changes and range checking included by default. + +c. A new implementation of fnmatch(3) that includes full POSIX.2 Basic + Regular Expression matching, including character classes, collating + symbols, equivalence classes, and support for case-insensitive pattern + matching. + +d. ksh-88 egrep-style extended pattern matching ([@+*?!](patlist)) has been + implemented, controlled by a new `shopt' option, `extglob'. + +e. There is a new ksh-like `[[' compound command, which implements + extended `test' functionality. + +f. There is a new `printf' builtin, implemented according to the POSIX.2 + specification. + +g.

There are new tilde prefixes which expand to directories from the + directory stack. + +i. There is a new `**' arithmetic operator to do exponentiation. + +j. There are new configuration options to control how bash is linked: + `--enable-profiling', to allow bash to be profiled with gprof, and + `--enable-static-link', to allow bash to be linked statically. + +k. There is a new configuration option, `--enable-cond-command', which + controls whether or not the `[[' command is included. It is on by + default. + +l. There is a new configuration option, `--enable-extended-glob', which + controls whether or not the ksh extended globbing feature is included. + It is enabled by default. + +m. There is a new configuration #define in config.h.top that, when enabled, + will cause all login shells to source /etc/profile and one of the user- + specific login shell startup files, whether or not the shell is + interactive. + +n. There is a new invocation option, `--dump-po-strings', to dump + a shell script's translatable strings ($"...") in GNU `po' format. + +o. There is a new `shopt' option, `nocaseglob', to enable case-insensitive + pattern matching when globbing filenames and using the `case' construct. + +p. There is a new `shopt' option, `huponexit', which, when enabled, causes + the shell to send SIGHUP to all jobs when an interactive login shell + exits. + +q. `bind' has a new `-u' option, which takes a readline function name as an + argument and unbinds all key sequences bound to that function in a + specified keymap. + +r. `disown' now has `-a' and `-r' options, to limit operation to all jobs + and running jobs, respectively. + +s. The `shopt' `-p' option now causes output to be displayed in a reusable + format. + +t. `test' has a new `-N' option, which returns true if the filename argument + has been modified since it was last accessed. + +u. `umask' now has a `-p' option to print output in a reusable format. + +v. A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...' + translation code. It expands to the character whose ascii code is NNN + in hexadecimal. + +w. The prompt string expansion code has a new `\r' escape sequence. + +x. The shell may now be cross-compiled for the CYGWIN32 environment on + a Unix machine. + +4. New Features in Readline + +a. There is now an option for `iterative' yank-last-arg handline, so a user + can keep entering `M-.', yanking the last argument of successive history + lines. + +b. New variable, `print-completions-horizontally', which causes completion + matches to be displayed across the screen (like `ls -x') rather than up + and down the screen (like `ls'). + +c. New variable, `completion-ignore-case', which causes filename completion + and matching to be performed case-insensitively. + +d. There is a new bindable command, `magic-space', which causes history + expansion to be performed on the current readline buffer and a space to + be inserted into the result. + +e. There is a new bindable command, `menu-complete', which enables tcsh-like + menu completion (successive executions of menu-complete insert a single + completion match, cycling through the list of possible completions). + +f. There is a new bindable command, `paste-from-clipboard', for use on Win32 + systems, to insert the text from the Win32 clipboard into the editing + buffer. + +g. The key sequence translation code now understands printf-style backslash + escape sequences, including \NNN octal escapes. These escape sequences + may be used in key sequence definitions or macro values. + +h. An `$include' inputrc file parser directive has been added. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.01.1-release, +and the previous version, bash-2.01-release. + +1. Changes to Bash + +a. The select command was fixed to check the validity of the user's + input more strenuously. + +b. A bug was fixed that prevented `time' from timing commands correctly + when supplied as an argument to `bash -c'. + +c. A fix was made to the mail checking code to keep from adding the same + mail file to the list of files to check multiple times when parsing + $MAILPATH. + +d.

Fixed a bug in the locale code that occurred when assigning a value + to LC_ALL. + +h. A change was made to the parser so that words of the form xxx=(...) + are not considered compound assignment statements unless there are + characters before the `='. + +i. A fix was made to the command tracing code to correctly quote each + word of output. + +j. Some changes were made to the bash-specific autoconf tests to make them + more portable. + +k. Completion of words with globbing characters now correctly quotes the + result. + +l. The directory /var/spool/mail is now preferred to /usr/spool/mail when + configure is deciding on the default mail directory. + +m. The brace completion code was fixed to not quote the `{' and `}'. + +n. Some fixes were made to make $RANDOM more random in subshells. + +o. System-specific changes were made to configure for: SVR4.2 + +p. Changes were made so that completion of words containing globbing chars + substitutes the result only if a single filename was matched. + +q. The window size is now recomputed after a job is stopped with SIGTSTP if + the user has set `checkwinsize' with `shopt'. + +r. When doing substring expansion, out-of-range substring specifiers now + cause nothing to be substituted rather than an expansion error. + +s. A fix was made so that you can no longer trap `SIGEXIT' or `SIGDEBUG' -- + only `EXIT' and `DEBUG' are accepted. + +t. The display of trapped signals now uses the signal number if signals + for which bash does not know the name are trapped. + +u. A fix was made so that `bash -r' does not turn on restricted mode until + after the startup files are executed. + +v.

A bug that occasionally caused unallocated memory to be passed to free() + when doing arithmetic substitution was fixed. + +x. A bug that caused a buffer overrun when expanding a prompt string + containing `\w' and ${#PWD} exceeded PATH_MAX was fixed. + +y. A problem with the completion code that occasionally caused it to + refer to a character before the beginning of the readline line buffer + was fixed. + +z. A bug was fixed so that the `read' builtin restarts reads when + interrupted by signals other than SIGINT. + +aa. Fixed a bug that caused a command to be freed twice when there was + an evaluation error in the `eval' command. + +2. Changes to Readline + +a. Added a missing `extern' to a declaration in readline.h that kept + readline from compiling cleanly on some systems. + +b. The history file is now opened with mode 0600 when it is written for + better security. + +c. Changes were made to the SIGWINCH handling code so that prompt redisplay + is done better. + +d. ^G now interrupts incremental searches correctly. + +e. A bug that caused a core dump when the set of characters to be quoted + when completing words was empty was fixed. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.01-release, +and the previous version, bash-2.01-beta2. + +1.

Fixed a bug that caused the bash emulation of strcasecmp to produce + incorrect results. + +c. A bug that caused memory to be freed twice when a trap handler resets + the trap more than once was fixed. + +d. A bug that caused machines where sizeof (pointer) > sizeof (int) to + fail (and possibly dump core) when trying to unwind-protect a null + pointer was fixed. + +e. The startup files should not be run with job control enabled. This fix + allows SIGINT to once again interrupt startup file execution. + +f. Bash should not change the SIGPROF handler if it is set to something + other than SIG_DFL. + +g. The completion code that provides bash-specific completions for readline + now quotes characters that the readline code would treat as word break + characters if they appear in a file name. + +h. The completion code now correctly quotes filenames containing a `!', + even if the user attempted to use double quotes when attempting + completion. + +i. A bug that caused the shell to dump core when `disown' was called without + arguments and there was no current job was fixed. + +j.

A couple of bugs that caused `fc' to not obey the `cmdhist' and `lithist' + shell options when editing and re-executing a series of commands were + fixed. + +l. A fix was made to the grammar -- the list of commands between `do' and + `done' in the body of a `for' command should be treated the same as a + while loop. + +2. Changes to Readline + +a. A couple of bugs that caused the history search functions to attempt to + free a NULL pointer were fixed. + +b. If the C library provides setlocale(3), readline does not need to look + at various environment variables to decide whether or not to go into + eight-bit mode automatically -- just check whether the current locale + is not `C' or `POSIX'. + +c. If the filename completion function finds that a directory was not closed + by a previous (interrupted) completion, it closes the directory with + closedir(). + +3. New Features in Bash + +a. New bindable readline commands: history-and-alias-expand-line and + alias-expand-line. The code was always in there, there was just no + way to execute it. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.01-beta1, +and the previous version, bash-2.01-alpha1. + +1. Changes to Bash + +a. Fixed a problem that could cause file descriptors used for process + substitution to conflict with those used explicitly in redirections. + +b.

The output of `set' and `export' is once again sorted, as POSIX wants. + +l. Fixed a problem caused by a recursive call reparsing the value of + $SHELLOPTS. + +m. The tilde code no longer calls getenv() when it's compiled as part of + the shell, which should eliminate problems on systems that cannot + redefine getenv(), like the NeXT OS. + +n. Fixed a problem that caused `bash -o' or `bash +o' to not list all + the shell options. + +o. Fixed `ulimit' to convert RLIM_INFINITY to the appropriate hard limit + only if the hard limit is greater than the current (soft) limit. + +p. Fixed a problem that arose when building bash in a different directory + than the source and y.tab.[ch] were remade with something other than + bison. This came up most often on NetBSD. + +q. Fixed a problem with completion -- it thought that `pwd`/[TAB] indicated + an unfinished command completion (`/), which generated errors. + +r. The bash special tilde expansions (~-, ~+) are now attempted before + calling the standard tilde expansion code, which should eliminate the + problems people have been seeing with this on Solaris 2.5.1. + +s. Added support for to places where it was missing. + +t. Changed the code that reads the output of a command substitution to not + go through stdio. This reduces the memory requirements and is faster. + +u. A number of changes to speed up export environment creation were made. + +v. A number of memory leaks were fixed as the result of running the test + scripts through Purify. + +w. Fixed a bug that caused subshells forked to interpret executable + scripts without a leading `#!' to not reinitialize the values of + the shell options. + +2. Changes to Readline + +a. History library has less `#ifdef SHELL' code -- abstracted stuff out + into application-specific function hooks. + +b. Readline no longer calls getenv() if it's compiled as part of the shell, + which should eliminate problems on systems that cannot redefine getenv(), + like the NeXT OS. + +c. Fixed translation of ESC when `untranslating' macro values. + +d. The region kill operation now fixes the mark if it ends up beyond the + boundaries of the line after the region is deleted. + +3. New Features in Bash + +a. New argument for `configure': `--with-curses'. This can be used to + override the selection of the termcap library on systems where it is + deficient. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.01-alpha1, +and the previous version, bash-2.0-release. + +1. Changes to Bash + +a. System-specific configuration changes for: FreeBSD, SunOS4, Irix, + MachTen, QNX 4.2, Harris Night Hawk, SunOS5. + +b. System-specific code changes were made for: Linux, 4.4 BSD, QNX 4.2, + HP-UX, AIX 4.2. + +c. A bug that caused the exec builtin to fail because the full pathname of + the command could not be found was fixed. + +d. The code that performs output redirections is now more resistant to + race conditions and possible security exploits. + +e. A bug that caused the shell to dump core when performing pattern + substitutions on variable values was fixed. + +f. More hosts are now recognized by the auto-configuration mechanism + (OpenBSD, QNX, others). + +g. Assignments to read-only variables that attempt to convert them to + arrays are now errors. + +h. A bug that caused shell scripts using array assignments in POSIX mode + to exit after the assignment was performed was fixed. + +i. The substring expansion code is now more careful about running off the + ends of the expanded variable value. + +j. A bug that caused completion to fail if a backquoted command substitution + appeared anywhere on the line was fixed. + +k. The `source' builtin no longer turns off history if it has been enabled + in a non-interactive shell. + +l. A bug that caused the shell to crash when `disown' was given a pid + instead of a job number was fixed. + +m. The `cd' spelling correction code will not try to change to `.' if no + directory entries match a single-character argument. + +n. A bad variable name supplied to `declare', `export', or `readonly' no + longer causes a non-interactive shell in POSIX mode to exit. + +o. Some fixes were made to the test suite to handle peculiarities of + various Unix versions. + +p. The bash completion code now quotes characters that readline would + treat as word breaks for completion but are not shell metacharacters. + +q. Bad options supplied at invocation now cause a usage message to be + displayed. + +r. Fixes were made to the code that handles DEBUG traps so that the trap + string is not freed inappropriately. + +s. Some changes were made to the bash debugger in examples/bashdb -- it + should be closer to working now. + +t. A problem that caused the default filename used for mail checking to be + wrong was fixed. + +u. A fix was made to the `echo' builtin so that NUL characters printed with + `echo -e' do not cause the output to be truncated. + +v. A fix was made to the job control code so that the shell behaves better + when monitor mode is enabled in a non-interactive shell. + +w. Bash no longer catches all of the terminating signals in a non- + interactive shell until a trap is set on EXIT, which should result in + quicker startup. + +x. A fix was made to the command timing code so that `time' can be used in + a loop. + +y. A fix was made to the parser so that `((cmd); cmd2)' is now parsed as + a nested subshell rather than strictly as an (erroneous) arithmetic + command. + +z. A fix was made to the globbing code so that it correctly matches quoted + filenames beginning with a `.'. + +aa. A bug in `fc' that caused some multi-line commands to not be stored as + one command in the history when they were re-executed after editing + (with `fc -e') was fixed. + +bb. The `ulimit' builtin now attempts to catch some classes of integer + overflows. + +cc.

A bug that caused the shell to fail to compile when configured with + `--disable-readline' was fixed. + +hh. The globbing code should now be interruptible. + +ii. Bash now notices when the `kill' builtin is used to send SIGCONT to a + stopped job and adjusts the data structures accordingly, as if `bg' had + been executed instead. + +jj. A bug that caused the shell to crash when mixing calls to `getopts' + and `shift' on the same set of positional parameters was fixed. + +kk. The command printing code now preserves the `-p' flag to `time'. + +ll. The command printing code now handles here documents better when there + are other redirections associated with the command. + +mm. The special glibc environment variable (NNN_GNU_nonoption_argv_flags_) + is no longer placed into the environment of executed commands -- users + of glibc had too many problems with it. + +nn. Reorganized the code that generates signames.h. The signal_names list + is now more complete but may be slightly different (SIGABRT is favored + over SIGIOT, for example). The preferred signal names are those + listed in the POSIX.2 standard. + +oo. `bashbug' now uses a filename shorter than 14 characters for its + temporary file, and asks for confirmation before sending the bug + report. + +pp. A bug that caused TAB completion in vi editing mode to not be turned + off when `set -o posix' was executed or back on when `set +o posix' + was executed was fixed. + +qq. A bug in the brace expansion code that caused brace expansions appearing + in new-style $(...) command substitutions to be inappropriately expanded + was fixed. + +rr. A bug in the readline hook shell-expand-line that could cause memory to + be inappropriately freed was fixed. + +ss. A bug that caused some arithmetic expressions containing `&&' and `||' + to be parsed with the wrong precedence has been fixed. + +tt. References to unbound variables after `set -u' has been executed now + cause the shell to exit immediately, as they should. + +uu. A bug that caused the shell to exit inappropriately when `set -e' had + been executed and a command's return status was being inverted with the + `!' reserved word was fixed. + +vv. A bug that could occasionally cause the shell to crash with a + divide-by-zero error when timing a command was fixed. + +ww. A bug that caused parameter pattern substitution to leave stray + backslashes in the replacement string when the expression is in + double quotes was fixed. + +xx. The `break' and `continue' builtins now break out of all loops when an + invalid count argument is supplied. + +yy. Fixed a bug that caused PATH to be set to the empty string if + `command -p' is executed with PATH unset. + +zz. Fixed `kill -l signum' to print the signal name without the `SIG' prefix, + as POSIX specifies. + +aaa. Fixed a bug that caused the shell to crash while setting $SHELLOPTS + if there were no shell options set. + +bbb. Fixed `export -p' and `readonly -p' so that when the shell is in POSIX + mode, their output is as POSIX.2 specifies. + +ccc. Fixed a bug in `readonly' so that `readonly -a avar=(...)' actually + creates an array variable. + +ddd. Fixed a bug that prevented `time' from correctly timing background + pipelines. + +2.

Non-printable characters are now expanded when displaying macros and + their values. + +f. The `dump-variables' and `dump-macros' commands now output a leading + newline if they're called as the result of a key sequence, rather + than directly by an application. + +3. New Features in Bash + +a. There is a new builtin array variable: GROUPS, the set of groups to which + the user belongs. This is used by the test suite. + +4. New Features in Readline + +a. If a key sequence bound to `universal-argument' is read while reading a + numeric argument started with `universal-argument', it terminates the + argument but is otherwise ignored. This provides a way to insert multiple + instances of a digit string, and is how GNU emacs does it. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.0-release, +and the previous version, bash-2.0-beta3. + +1. Changes to Bash + +a. Fix to the `getopts' builtin so that it does the right thing when a + required option argument is not present. + +b.

Linux systems now have a working `ulimit -v', using RLIMIT_AS. + +j. Updated config.guess so that many more machine types are recognized. + +k. Fixed a bug with backslash-quoted slashes in the ${param/pat[/sub]} + expansion. + +l. If the shell is named `-su', and `-c command' is supplied, read and + execute the login shell startup files even though the shell is not + interactive. This is to support the `-' option to `su'. + +m. Fixed a bug that caused core dumps when the DEBUG trap was ignored + with `trap "" DEBUG' and a shell function was subsequently executed. + +n. Fixed a bug that caused core dumps in the read builtin when IFS was + set to the null string and the input had leading whitespace. + +2. Changes to Readline + +a. Fixed a bug that caused a numeric argument of 1024 to be ignored when + inserting text. + +b. Fixed the display code so that the numeric argument is displayed as it's + being entered. + +c. Fixed the numeric argument reading code so that `M-- command' is + equivalent to `M--1 command', as the prompt implies. + +3. New Features in Bash + +a. `ulimit' now sets both hard and soft limits and reports the soft limit + by default (when neither -H nor -S is specified). This is compatible + with versions of sh and ksh that implement `ulimit'. + +b. Integer constants have been extended to base 64. + +4. New Features in Readline + +a. The `home' and `end' keys are now bound to beginning-of-line and + end-of-line, respectively, if the corresponding termcap capabilities + are present. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.0-beta3, +and the previous version, bash-2.0-beta2. + +1. Changes to Bash + +a. System-specific changes for: AIX 4.2, SCO 3.2v[45], HP-UX. + +b. When in POSIX mode, variable assignments preceding a special builtin + persist in the shell environment after the builtin completes. + +c. Changed all calls to getwd() to getcwd(). Improved check for systems + where the libc getcwd() calls popen(), since that breaks on some + systems when job control is being used. + +d. Fixed a bug that caused seg faults when executing scripts with the + execute bit set but without a leading `#!'. + +e. The environment passed to executed commands is never sorted. + +f. A bug was fixed in the code that expands ${name[@]} to the number of + elements in an array variable. + +g. A bug was fixed in the array compound assignment code ( A=( ... ) ). + +h. Window size changes now correctly propagate down to readline if + the shopt `checkwinsize' option is enabled. + +i. A fix was made in the code that expands to the length of a variable + value (${#var}). + +j. A fix was made to the command builtin so that it did not turn on the + `no fork' flag inappropriately. + +k. A fix was made to make `set -n' work more reliably. + +l. A fix was made to the job control initialization code so that the + terminal process group is set to the shell's process group if the + shell changes its own process group. + +2. Changes to Readline + +a. System-specific changes for: SCO 3.2v[45]. + +b. The behavior of the vi-mode `.' when redoing an `i' command was changed + to insert the text previously inserted by the `i' command rather than + simply entering insert mode. + +3. New features in Bash + +a. There is a new version of the autoload function package, in + examples/functions/autoload.v2, that uses arrays and provides more + functionality. + +b. Support for LC_COLLATE and locale-specific sorting of the results of + pathname expansion if strcoll() is available. + +4. New Features in Readline + +a. Support for locale-specific sorting of completion possibilities if + strcoll() is available. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.0-beta2, +and the previous version, bash-2.0-beta1. + +1. Changes to Bash + +a. `pushd -' is once again equivalent to `pushd $OLDPWD'. + +b. OS-specific changes for: SCO 3.2v[45]. + +c. A change was made to the fix for the recently-reported security hole + when reading characters with octal value 255 to make it work better on + systems with restartable system calls when not using readline. + +d. Some changes were made to the test suite so that it works if you + configure bash with --enable-usg-echo-default. + +e. A fix was made to the parsing of conditional arithmetic expressions. + +f. Illegal arithmetic bases now cause an arithmetic evaluation error rather + than being silently reset. + +g. Multiple arithmetic bases now cause an arithmetic evaluation error + instead of being ignored. + +h. A fix was made to the evaluation of ${param?word} to conform to POSIX.2. + +i. A bug that sometimes caused array indices to be evaluated twice (which + would cause errors when they contained assignment statements) was fixed. + +j. `ulimit' was rewritten to avoid problems with getrlimit(2) returning + unsigned values and to simplify the code. + +k. A bug in the command-oriented-history code that caused it to sometimes + put semicolons after right parens inappropriately was fixed. + +l. The values inserted into the prompt by the \w and \W escape sequences + are now quoted to prevent further expansion. + +m. An interactive shell invoked as `sh' now reads and executes commands + from the file named by $ENV when it starts up. If it's a login shell, + it does this after reading /etc/profile and ~/.profile. + +n. The file named by $ENV is never read by non-interactive shells. + +2. Changes to Readline + +a. A few changes were made to hide some macros and functions that should not + be public. + +b. An off-by-one error that caused seg faults in the history expansion code + was fixed. + +3. New Features in Bash + +a. The ksh-style ((...)) arithmetic command was implemented. It is exactly + identical to let "...". This is controlled by a new option to configure, + `--enable-dparen-arithmetic', which is on by default. + +b. There is a new #define available in config.h.top: SYS_BASH_LOGOUT. If + defined to a filename, bash reads and executes commands from that file + when a login shell exits. It's commented out by default. + +c. `ulimit' has a `-l' option that reports the maximum amount of data that + may be locked into memory on 4.4BSD-based systems. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.0-beta1, +and the previous version, bash-2.0-alpha4. + +1. Changes to Bash + +a. A bug that sometimes caused traps to be ignored on signals the + shell treats specially was fixed. + +b. The internationalization code was changed to track the values of + LC_* variables and call setlocale() as appropriate. The TEXTDOMAIN + and TEXTDOMAINDIR variables are also tracked; changes cause calls + to textdomain() and bindtextdomain(), if available. + +c. A bug was fixed that sometimes caused double-quoted strings to be + parsed incorrectly. + +d. Changes were made so that the siglist code compiles correctly on + Solaris 2.5. + +e. Added `:' to the set of characters that cause word breaks for the + completion code so that pathnames in assignments to $PATH can be + completed. + +f. The `select' command was fixed to print $PS3 to stderr. + +g. Fixed an error in the manual page section describing the effect that + setting and unsetting GLOBIGNORE has on the setting of the `dotglob' + option. + +h. The time conversion code now uses CLK_TCK rather than CLOCKS_PER_SEC + on systems without gettimeofday() and resources. + +i. The getopt static variables are now initialized each time a subshell + is started, so subshells using `getopts' work right. + +j. A sign-extension bug that caused a possible security hole was fixed. + +k. The parser now reads characters between backquotes within a double- + quoted string as a single word, so double quotes in the backquoted + string don't terminate the enclosing double-quoted string. + +l. A bug that caused `^O' to work incorrectly when typed as the first + thing to an interactive shell was fixed. + +m. A rarely-exercised off-by-one error in the code that quotes variable + values was fixed. + +n. Some memory and file descriptor leaks encountered when running a + shell script that is executable but does not have a leading `#!' + were plugged. + +2. Changes to Readline + +a. A bug that sometimes caused incorrect results when trying to read + typeahead on systems without FIONREAD was fixed. + +3. New Features in Bash + +a. The command timing code now uses the value of the TIMEFORMAT variable + to format and display timing statistics. + +b. The `time' reserved word now accepts a `-p' option to force the + POSIX.2 output format. + +c. There are a couple of new and updated scripts to convert csh startup + files to bash format. + +d. There is a new builtin array variable: BASH_VERSINFO. The various + members hold the parts of the version information in BASH_VERSION, + plus the value of MACHTYPE. + +4. New Features in Readline + +a. Setting LANG to `en_US.ISO8859-1' now causes readline to enter + eight-bit mode. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.0-alpha4, +and the previous version, bash-2.0-alpha3. + +1. Changes to Bash + +a. There is better detection of rsh connections on Solaris 2. + +b. Assignments to read-only variables preceding a command name are now + variable assignment errors. Variable assignment errors cause + non-interactive shells running in posix mode to exit. + +c. The word tokenizer was rewritten to handle nested quotes and pairs + ('', "", ``, ${...}, $(...), $[...], $'...', $"...", <(...), >(...)) + correctly. Some of the parameter expansion code was updated as a + consequence. + +d. A fix was made to `test' when given three arguments so that a binary + operator is checked for first, before checking that the first argument + is `!'. + +e. 2''>/dev/null is no longer equivalent to 2>/dev/null. + +f. Parser error messages were regularized, and in most cases the name of + the shell script being read by a non-interactive shell is not printed + twice. + +g. A fix was made to the completion code so that it no longer removes the + text the user typed in some cases. + +h. The special glibc `getopt' environment variable is no longer put into + the environment on machines with small values of ARG_MAX. + +i. The expansion of ${...} now follows the POSIX.2 rules for finding the + closing `}'. + +j. The shell no longer displays spurious status messages for background + jobs in shell scripts that complete successfully when the script is + run from a terminal. + +k. `shopt -o' now correctly updates $SHELLOPTS. + +l. A bug that caused the $PATH searching code to return a non-executable + file even when an executable file with the same name appeared later in + $PATH was fixed. + +m. The shell now does tilde expansions on unquoted `:~' in assignment + statements when not in posix mode. + +n. Variable assignment errors when a command consists only of assignments + now cause non-interactive shells to exit when in posix mode. + +o. If the variable in a `for' or `select' command is read-only, or not a + legal shell identifier, a variable assignment error occurs. + +p. `test' now handles `-a' and `-o' as binary operators when three arguments + are supplied, and correctly parses `( word )' as equivalent to `word'. + +q. `test' was fixed so that file names of the form /dev/fd/NN mean the same + thing on all systems, even Linux. + +r. Fixed a bug in the globbing code that caused patterns with multiple + consecutive `*'s to not be matched correctly. + +s. Fixed a bug that caused $PS2 to not be printed when an interactive shell + not using readline is reading a here document. + +t. Fixed a bug that caused history expansion to be performed inappropriately + when a single-quoted string spanned more than one line. + +u. `getopts' now checks that the variable name passed by the user as the + second argument is a legal shell identifier and that the variable is + not read-only. + +v. Fixed `getopts' to obey POSIX.2 rules for setting $OPTIND when it + encounters an error. + +w. Fixed `set' to display variable values in a form that can be re-read. + +x. Fixed a bug in the code that keeps track of whether or not local variables + have been declared at the current level of function nesting. + +y. Non-interactive shells in posix mode now exit if the name in a function + declaration is not a legal identifier. + +z. The job control code now ignores stopped children when the shell is not + interactive. + +aa. The `cd' builtin no longer attempts spelling correction on the directory + name if the shell is not interactive, regardless of the setting of the + `cdspell' option. + +bb. Some OS-specific changes were made for SCO 3.2v[45] and AIX 4.2. + +cc. `time' now prints its output to stderr, as POSIX.2 specifies. + +2. Fixes to Readline + +a. After printing possible completions, all lines of a multi-line prompt + are redisplayed. + +b. Some changes were made to the terminal handling code in rltty.c to + work around AIX 4.2 bugs. + +3. New Features in Bash + +a. There is a new loadable builtin: sprintf, with calling syntax + sprintf var format [args] + This provides an easy way to simulate ksh left- and right-justified + variable values. + +b. The expansions of \h and \H in prompt strings were swapped. \h now + expands to the hostname up to the first `.', as in bash-1.14. + +4. New Features in Readline + +a. The bash-1.14 behavior when ^M is typed while doing an incremental + search was restored. ^J may now be used to terminate the search without + accepting the line. + +b. There is a new bindable variable: disable-completion. This inhibits + word completion and causes the completion character to be inserted as + if it had been bound to self-insert. + +------------------------------------------------------------------------------ +This document details the changes between this version, bash-2.0-alpha3, +and the previous version, bash-2.0-alpha2. + +There is now a file `COMPAT' included in the distribution that lists the +user-visible incompatibilities between 1.14 and 2.0. + +1. Changes to Bash + +a. Some work was done so that word splitting of the rhs of assignment + statements conforms more closely to historical practice. + +b. A couple of errant memory frees were fixed. + +c. A fix was made to the test builtin so it recognizes `<' and `>' as + binary operators. + +d. The GNU malloc in lib/malloc/malloc.c now scrambles memory as it's + allocated and freed. This is to catch callers that refer to freed + memory or assume something about newly-allocated memory. + +e. Fixed a problem with conversion to 12-hour time in the prompt + expansion code. + +f. Fixed a problem with configure's argument parsing order. Now you can + correctly turn on specific options after using --enable-minimal-config. + +g. The configure script now automatically disables the use of GNU malloc + on systems where it's appropriate (better than having people read the + NOTES file and do it manually). + +h. There are new prompt expansions (\v and \V) to insert version information + into the prompt strings. + +i. The default prompt string now includes the version number. + +j. Most of the builtins that take no options were changed to use the + internal getopt so they can produce proper error messages for -? + and incorrect options. + +k. Some system-specific changes were made for SVR4.2 and Solaris 2.5. + +l. Bash now uses PATH_MAX instead of MAXPATHLEN and NAME_MAX instead of + MAXNAMLEN. + +m. A couple of problems caused by uninitialized variables were fixed. + +n. There are a number of new loadable builtin examples: logname, basename, + dirname, tty, pathchk, tee, head, and rmdir. All of these conform to + POSIX.2. + +o. Bash now notices changes in TZ and calls tzset() if present, so + changing TZ will alter the time printed by prompt expansions. + +p. The source was reorganized a bit so I don't have to wait so long for + some files to compile, and to facilitate the creation of a `shell + library' at some future point. + +q. Bash no longer turns off job control if called as `sh', since the + POSIX.2 spec includes job control as a standard feature. + +r. `bash -o posix' now works as intended. + +s. Fixed a problem with the completion code: when completing a filename + that contained globbing characters, if show-all-if-ambiguous was set, + the completion code would remove the user's text. + +t. Fixed ulimit so that (hopefully) the full range of limits is available + on HPUX systems. + +u. A new `shopt' option (`hostcomplete') enables and disables hostname + completion. + +v. The shell no longer attempts to save the history on an abort(), + which is usually called by programming_error(). + +w. The `-s' option to `fc' was changed to echo the command to be executed + to stderr instead of stdout. + +x. If the editor invoked by `fc -e' exits with a non-zero status, no + commands are executed. + +y. Fixed a bug that made the shopt `histverify' option work incorrectly. + +z. There is a new variable `MACHTYPE' whose value is the GNU-style + `cpu-company-system' system description as set by configure. (The + values of MACHTYPE and HOSTTYPE should really be swapped.) + +aa. The `ulimit' builtin now allows the maximum virtual memory size to be + set via setrlimit(2) if RLIMIT_VMEM is defined. + +bb. `bash -nc 'command'' no longer runs `command'. + +2. Changes to Readline + +a. Fixed a typo in the code that checked for FIONREAD in input.c. + +b. Fixed a bug in the code that outputs keybindings, so things like C-\ + are quoted properly. + +c. Fixed a bug in the inputrc file parsing code to handle the problems + caused by inputrc files created from the output of `bind -p' in + previous versions of bash. The problem was due to the bug fixed + in item b above. + +d. Readline no longer turns off the terminal's meta key, and turns it on + once the first time it's called. + +------------------------------------------------------------------------------ +This file documents the changes between this version, bash-2.0-alpha2, +and the previous version, bash-2.0-alpha. + +1. Changes to Bash + +a. The shell no longer thinks directories are executable. + +b. `disown' has a new option, `h', which inhibits the resending of SIGHUP + but does not remove the job from the jobs table. + +c. The varargs functions in error.c now use ANSI-C `stdarg' if available. + +d. The build process now treats the `build version' in .build as local to + the build directory, so different versions built from the same source + tree have different `build versions'. + +e. Some problems with the grammar have been fixed. (It used `list' in a few + productions where `compound_list' was needed. A `list' must be terminated + with a newline or semicolon; a `compound_list' need not be.) + +f. A fix was made to keep `wait' from hanging when waiting for all background + jobs. + +g. `bash --help' now writes its output to stdout, like the GNU Coding Standards + specify, and includes the machine type (the value of MACHTYPE). + +h. `bash --version' now prints more information and exits successfully, like + the GNU Coding Standards specify. + +i. The output of `time' and `times' now prints fractional seconds with three + places after the decimal point. + +j. A bug that caused process substitutions to screw up the pipeline printed + by `jobs' was fixed. + +k. Fixes were made to the code that implements $'...' and $"..." so they + work as documented. + +l. The process substitution code now opens named pipes for reading with + O_NONBLOCK to avoid hanging. + +m. Fixes were made to the trap code so the shell cleans up correctly if the + trap command contains a `return' and we're executing a function or + sourcing a script with `.'. + +n. Fixes to doc/Makefile.in so that it doesn't try to remake all of the + documentation (ps, dvi, etc.) on a `make install'. + +o. Fixed an auto-increment error that caused bash -c args to sometimes dump + core. + +p. Fixed a bug that caused $HISTIGNORE to fail when the history line + contained globbing characters. + +2. Changes to Readline + +a. There is a new string variable, rl_library_version, available for use by + applications. The current value is "2.1". + +b. A bug encountered when expand-tilde was enabled and file completion was + attempted on a word beginning with `~/' was fixed. + +c. A slight change was made to the incremental search termination behavior. + ESC still terminates the search, but if input is pending or arrives + within 0.1 seconds (on systems with select(2)), it is used as a prefix + character. This is intented to allow users to terminate searches with + the arrow keys and get the behavior they expect. diff --git a/bash-20060316/COMPAT b/bash-20060316/COMPAT new file mode 100644 index 000000000..df64c03da --- /dev/null +++ b/bash-20060316/COMPAT @@ -0,0 +1,258 @@ +This document details the incompatibilities between this version of bash, +bash-3.1, and the previous widely-available versions, bash-1.14 (which is +still the `standard' version for a few Linux distributions) and bash-2.x. +These were discovered by users of bash-2.x and 3.x, so this list is not +comprehensive. Some of these incompatibilities occur between the current +version and versions 2.0 and above. (The differences between bash-1.14 and +bash-2.0 were significant.) + +1. Bash uses a new quoting syntax, $"...", to do locale-specific + string translation. Users who have relied on the (undocumented) + behavior of bash-1.14 will have to change their scripts. For + instance, if you are doing something like this to get the value of + a variable whose name is the value of a second variable: + + eval var2=$"$var1" + + you will have to change to a different syntax. + + This capability is directly supported by bash-2.0: + + var2=${!var1} + + This alternate syntax will work portably between bash-1.14 and bash-2.0: + + eval var2=\$${var1} + +2. One of the bugs fixed in the YACC grammar tightens up the rules + concerning group commands ( {...} ). The `list' that composes the + body of the group command must be terminated by a newline or + semicolon. That's because the braces are reserved words, and are + recognized as such only when a reserved word is legal. This means + that while bash-1.14 accepted shell function definitions like this: + + foo() { : } + + bash-2.0 requires this: + + foo() { :; } + + This is also an issue for commands like this: + + mkdir dir || { echo 'could not mkdir' ; exit 1; } + + The syntax required by bash-2.0 is also accepted by bash-1.14. + +3. The options to `bind' have changed to make them more consistent with + the rest of the bash builtins. If you are using `bind -d' to list + the readline key bindings in a form that can be re-read, use `bind -p' + instead. If you were using `bind -v' to list the key bindings, use + `bind -P' instead. + +4. The `long' invocation options must now be prefixed by `--' instead + of `-'. (The old form is still accepted, for the time being.) + +5. There was a bug in the version of readline distributed with bash-1.14 + that caused it to write badly-formatted key bindings when using + `bind -d'. The only key sequences that were affected are C-\ (which + should appear as \C-\\ in a key binding) and C-" (which should appear + as \C-\"). If these key sequences appear in your inputrc, as, for + example, + + "\C-\": self-insert + + they will need to be changed to something like the following: + + "\C-\\": self-insert + +6. A number of people complained about having to use ESC to terminate an + incremental search, and asked for an alternate mechanism. Bash-2.03 + uses the value of the settable readline variable `isearch-terminators' + to decide which characters should terminate an incremental search. If + that variable has not been set, ESC and Control-J will terminate a + search. + +7. Some variables have been removed: MAIL_WARNING, notify, history_control, + command_oriented_history, glob_dot_filenames, allow_null_glob_expansion, + nolinks, hostname_completion_file, noclobber, no_exit_on_failed_exec, and + cdable_vars. Most of them are now implemented with the new `shopt' + builtin; others were already implemented by `set'. Here is a list of + correspondences: + + MAIL_WARNING shopt mailwarn + notify set -o notify + history_control HISTCONTROL + command_oriented_history shopt cmdhist + glob_dot_filenames shopt dotglob + allow_null_glob_expansion shopt nullglob + nolinks set -o physical + hostname_completion_file HOSTFILE + noclobber set -o noclobber + no_exit_on_failed_exec shopt execfail + cdable_vars shopt cdable_vars + +8. `ulimit' now sets both hard and soft limits and reports the soft limit + by default (when neither -H nor -S is specified). This is compatible + with versions of sh and ksh that implement `ulimit'. The bash-1.14 + behavior of, for example, + + ulimit -c 0 + + can be obtained with + + ulimit -S -c 0 + + It may be useful to define an alias: + + alias ulimit="ulimit -S" + +9. Bash-2.01 uses a new quoting syntax, $'...' to do ANSI-C string + translation. Backslash-escaped characters in ... are expanded and + replaced as specified by the ANSI C standard. + +10. The sourcing of startup files has changed somewhat. This is explained + more completely in the INVOCATION section of the manual page. + + A non-interactive shell not named `sh' and not in posix mode reads + and executes commands from the file named by $BASH_ENV. A + non-interactive shell started by `su' and not in posix mode will read + startup files. No other non-interactive shells read any startup files. + + An interactive shell started in posix mode reads and executes commands + from the file named by $ENV. + +11. The <> redirection operator was changed to conform to the POSIX.2 spec. + In the absence of any file descriptor specification preceding the `<>', + file descriptor 0 is used. In bash-1.14, this was the behavior only + when in POSIX mode. The bash-1.14 behavior may be obtained with + + <>filename 1>&0 + +12. The `alias' builtin now checks for invalid options and takes a `-p' + option to display output in POSIX mode. If you have old aliases beginning + with `-' or `+', you will have to add the `--' to the alias command + that declares them: + + alias -x='chmod a-x' --> alias -- -x='chmod a-x' + +13. The behavior of range specificiers within bracket matching expressions + in the pattern matcher (e.g., [A-Z]) depends on the current locale, + specifically the value of the LC_COLLATE environment variable. Setting + this variable to C or POSIX will result in the traditional ASCII behavior + for range comparisons. If the locale is set to something else, e.g., + en_US (specified by the LANG or LC_ALL variables), collation order is + locale-dependent. For example, the en_US locale sorts the upper and + lower case letters like this: + + AaBb...Zz + + so a range specification like [A-Z] will match every letter except `z'. + Other locales collate like + + aAbBcC...zZ + + which means that [A-Z] matches every letter except `a'. + + The portable way to specify upper case letters is [:upper:] instead of + A-Z; lower case may be specified as [:lower:] instead of a-z. + + Look at the manual pages for setlocale(3), strcoll(3), and, if it is + present, locale(1). + + You can find your current locale information by running locale(1): + + caleb.ins.cwru.edu(2)$ locale + LANG=en_US + LC_CTYPE="en_US" + LC_NUMERIC="en_US" + LC_TIME="en_US" + LC_COLLATE="en_US" + LC_MONETARY="en_US" + LC_MESSAGES="en_US" + LC_ALL=en_US + + My advice is to put + + export LC_COLLATE=C + + into /etc/profile and inspect any shell scripts run from cron for + constructs like [A-Z]. This will prevent things like + + rm [A-Z]* + + from removing every file in the current directory except those beginning + with `z' and still allow individual users to change the collation order. + Users may put the above command into their own profiles as well, of course. + +14. Bash versions up to 1.14.7 included an undocumented `-l' operator to + the `test/[' builtin. It was a unary operator that expanded to the + length of its string argument. This let you do things like + + test -l $variable -lt 20 + + for example. + + This was included for backwards compatibility with old versions of the + Bourne shell, which did not provide an easy way to obtain the length of + the value of a shell variable. + + This operator is not part of the POSIX standard, because one can (and + should) use ${#variable} to get the length of a variable's value. + Bash-2.x does not support it. + +15. Bash no longer auto-exports the HOME, PATH, SHELL, TERM, HOSTNAME, + HOSTTYPE, MACHTYPE, or OSTYPE variables. + +16. Bash no longer initializes the FUNCNAME, GROUPS, or DIRSTACK variables + to have special behavior if they appear in the initial environment. + +17. Bash no longer removes the export attribute from the SSH_CLIENT or + SSH2_CLIENT variables, and no longer attempts to discover whether or + not it has been invoked by sshd in order to run the startup files. + +18. Bash no longer requires that the body of a function be a group command; + any compound command is accepted. + +19. As of bash-3.0, the pattern substitution operators no longer perform + quote removal on the pattern before attempting the match. This is the + way the pattern removal functions behave, and is more consistent. + +20. After bash-3.0 was released, I reimplemented tilde expansion, incorporating + it into the mainline word expansion code. This fixes the bug that caused + the results of tilde expansion to be re-expanded. There is one + incompatibility: a ${paramOPword} expansion within double quotes will not + perform tilde expansion on WORD. This is consistent with the other + expansions, and what POSIX specifies. + +21. A number of variables have the integer attribute by default, so the += + assignment operator returns expected results: RANDOM, LINENO, MAILCHECK, + HISTCMD, OPTIND. + +22. Bash-3.x is much stricter about $LINENO correctly reflecting the line + number in a script; assignments to LINENO have little effect. + +23. By default, readline binds the terminal special characters to their + readline equivalents. As of bash-3.1/readline-5.1, this is optional and + controlled by the bind-tty-special-chars readline variable. + +24. The \W prompt string expansion abbreviates $HOME as `~'. The previous + behavior is available with ${PWD##/*/}. + +25. The arithmetic exponentiation operator is right-associative as of bash-3.1. + +26. The rules concerning valid alias names are stricter, as per POSIX.2. + +27.

This is to say, there is +no requirement for Bash to print a notice when it is started +interactively in the usual way. We made this exception because users +and standards expect shells not to print such messages. This +exception applies to any program that serves as a shell and that is +based primarily on Bash as opposed to other GNU software. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19yy name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

The Sun +malloc allows you to free things multiple times, instead of doing the old + + if (x) + free(x); + x = NULL; + +trick. The Gnu malloc disallows that. + +The root of this set of problems is that the Sun yyparse() is not reentrant +(`impure'). First of all, /usr/lib/yaccpar has changed a number of things +to be dynamically allocated that were once static arrays (the state stack +and the value stack are the two major ones). Second, some things that used +to be automatic variables to yyparse (like the state stack) are now +globally static variables in /usr/lib/yaccpar. This means no more +indirectly recursive calls to yyparse(). This is pure bogusness, and +breaks backwards compatibility in a major way. + +The first indirect call to yyparse() occurs when PROMPT_COMMAND is run +through parse_and_execute() (parse.y, around line 1200). The next call to +yyparse() in your example (hitting return) returns quickly, putting nothing +onto the state stack. Of course, YYACCEPT doesn't check whether anything +was put into the stack; it just goes ahead and frees it anyway. + +The next problem arises when PROMPT_COMMAND contains a backquoted command, +which is run through parse_and_execute() again. It doesn't matter that +this parse_and_execute is in a subshell; the data structures being built by +Sun's yacc come along for free when bash forks. The state stack gets all +screwed up and a segmentation fault is the inevitable result. If Sun (and, +I assume, AT&T, since the SCCS line at the top of /usr/lib/yaccpar +indicates that it is derived from S5R3.1) wants to do this kind of shit, +they should at least provide a convenience function to clear out the state +stack. + +Both of these problems are avoided by using bison. I have put bison on +triton (you'll have to redo it if you want it; it looks for the parser +skeletons in /home/chet/lib), and a bash compiled with a bison-generated +parser does not crash given the above setting of PROMPT_COMMAND. That bash +is in /home/chet/bin. I don't know how to solve these problems in a +simple way by using the Sun yacc. + +`Byacc' (Berkeley Yacc), the 4.4 BSD rewrite of Yacc by Bob Corbett (who +wrote the original version of bison), should also be OK, though I haven't +looked at it. + +> That brings up something else: Triton is set up as a mail-less +> machine (all mail is forwarded elsewhere).

I got scared after reading that + s5r4 provides 2048 fd's per process -- 2045 (mostly useless) + close() calls on *each executed program*? No way, no how. + + This caused the other fixes for this file to be discovered. + + Unfortunately (there always seems to be a catch), 4.3 BSD up to + 4.3-tahoe leaves a file descriptor open in setpwent() if you're + using dbm password files. 4.3+NFS does this if you're not using + YP. Arghhhhhhh... I haven't decided yet what to do about this; + probably just set fd 3 to close-on-exec when the shell is + initialized. + +execute_cmd.c + - removed the call to `add_undo_redirect()' when a file is being + closed with the redirection operators [n]<&- and [n]>&-. The + effect was to make those operators useless. Sad to say, I was + probably the dummy who put it in there... + +execute_cmd.c + - when calling fcntl(redirector, F_GETFD, 0) in do_redirection() to + find out if a file descriptor is active, do it only if redirector + is not the same as `fd', which you've just opened. This has + spectacularly bad consequences if you do something like + + exec 3/tmp/foo 5 `command' + + 12/1 + ---- +parse.y, shell.c, builtins.c, builtins.c.posix, make_cmd.c + - changed the way parsing of here documents works in the presence + of continued lines (unquoted backslash-newline pair or via quoting). + Now the shell reads up to an unquoted newline before trying to + read the contents of the here-document (that's the way sh works). + The changes are spread out over multiple files. + + The cases that this fixes are these: + + cat << EOF | sed -n \ + -e 'blah blah...' \ + -e 'more more...' + input + to + cat + for + sed + EOF + + cat << EOF | echo 'a b c + d e f + g h i' + EOF + + Previously, the yacc-generated bash parser would resolve the + `<< EOF' redirection and immediately try to create the here + document, and the rest of the command would become part of + the here document. + + Changes by file: + parse.y: + added two new variables, need_here_doc, and + redirection_needing_here_doc. The yacc actions + associated with the here-document productions + were modified to set these variables appropriately. + Changed read_token to read the text of any pending + here-documents just before it returns an unquoted + newline to the parser. + make_cmd.c: + moved the code that reads the text of the + here-document out of make_redirection into a new + function named make_here_document. The cases in + make_redirection don't do anything now; they just + set the EOF marker and return + shell.c: + added a wrapper function around yyparse called + parse_command that initializes the above variables, + calls parse_command, then makes the here-document + if necessary by calling make_here_document (usually + it doesn't need to; read_token has already done it). + builtins.c.posix: + builtins.c: + changed the call to yyparse to a call to parse_command + (in parse_and_execute) + +subst.c + - for some reason which I have not yet fully divined, a shell whose + standard output (file descriptor 1) is closed cannot perform + backquote substitution if the child closes both sides of the pipe + after dup2(fildes[1], 1). The obvious fix is to not close + fildes[0] in the child, but it's not intuitive. I got the example + from the Dec Ultrix 4.0 release notes: + + exec >&- + echo `echo hi` >&2 + + The 4.3 BSD sh has the same problem. I'm stumped. + + (LATER NOTE: I'm not stumped anymore.) + + 12/2 + ---- +shell.c + - shells started to execute scripts (`bash file') should set + remember_on_history and history_expansion to 0. + - redid maybe_execute_file to eliminate a possibly unnecessary + call to stat. Just open the file immediately and call fstat + to get the size. Return if the open fails. + +execute_cmd.c + - redid same_file to eliminate some calls to stat(). Added two + new parameters, which, if non-null, are pointers to status + information about the pathnames passed. This required changes + to find_user_command_in_path. + - eliminated some calls to strlen in find_user_command_in_path + +builtins.c, builtins.c.posix + - changed calls to same_file to pass the two extra parameters + +parse.y + - only call pre_process_line in shell_getc if the shell is + interactive, because history expansion and remembering lines + on the history are not done for script shells + - make the shell echo comment lines (lines whose first character + is `#') by moving the after_pre_process label to just before + that code + - eliminated several calls to xrealloc in shell_getc when the + shell is non-interactive by correcting confusing uses of + shell_input_line_size -- after pre_process_line is called, it + must be set to strlen(shell_input_line) because we don't know + what the `true' allocated size of that block is, but not if + pre_process_line is never called. This became apparent + as a result of the previous two changes. + +readline/history.c + - make history_do_write abort on write errors instead of ignoring + them. + + 12/3 + ---- +general.c + - defined bcopy in terms of memcpy for USG systems + - changed the USG getwd to return the result of getcwd + + 12/4 + ---- +readline/vi_keymap.c, readline/funmap.c + - changed #ifdef FILE to #ifdef BUFSIZ as the test for a + previous inclusion of stdio.h + +general.c + - changed USG getwd emulation to return an error message in the + buffer if the getcwd fails + +subst.c + - fixed extern declaration of copy_word + +variables.c + - set_var_auto_export does a complete new lookup of the variable + it's setting. Most of the time in initialize_shell_variables + it's called immediately after bind_variable or set_if_not on + the same variable. Made set_if_not return a SHELL_VAR * like + bind_variable, then replaced the calls to set_var_auto_export + with calls to a new function set_auto_export that is passed a + SHELL_VAR * and skips the lookup. + +execute_cmd.c + - don't call print_simple_command in execute_simple_command if the + shell is not interactive, since the only place that's ever used + is pretty_print_job, which is never called if the shell is not + interactive.

Fix is to always + make sure `limit' is at least 1. + + 12/7 + ---- +readline/readline.c + - Add a new #define, HAVE_BSD_SIGNALS. This is for hybrid systems + like HP-UX (pre-Posix) that have both termio and the BSD reliable + signal mechanism (sigmask, sigblock, sigsetmask, etc.). This + allows better use of `critical sections' when changing the terminal + parameters. + +readline/history.c + - Need to #include for System V.4 + +makeargs.sh + - If we are on System V.4, define USGr4 and make it show through to + the rest of the build process + +machines.h + - changed the i386 entry to add support for recognizing System V.4 + machines + + 12/8 + ---- +shell.c + - made the TMOUT code be executed only for interactive shells + - .bashrc should not be run if the standard input and standard + output are not ttys + +machines.h + - reorganized the `i386' section so that all defines for a single + machine/OS combination are now grouped + + 12/9 + ---- +shell.c + - make the -s flag force interactive use only if all the other + conditions for interactive use are met + - since the same conditions are used to mark the shell as + interactive and to decide whether or not to execute the .bashrc, + only execute the .bashrc if we are interactive, and use the + value of `interactive' in the test + - only test if `file' in `bash file' is a binary file if the file + descriptor obtained by opening it is not a tty.

Now, instead of calling + parse_and_execute out of a signal handler (!), the signal handler + just sets a flag that the rest of the code checks at appropriate + times. This means traps are kind of like interrupts, but serviced + far fewer times. It also means a bit of a loss of immediacy. + + 12/12 + ----- + +shell.c + - fixed a bug in read_command that caused the handler for SIGALRM + to be reset to garbage each time through. + +variables.c + - change makunbound to call stupidly_hack_special_variables so + that things like `noclobber' and such can be reset properly + on function exit or when a `special' variable is unset. + + 12/14 + ----- +parse.y + - made `<>' without a number specifying the file descriptor open + the named file for both standard input and standard output. + +cpp-Makefile, jobs.h, endian.c, endian.h, endian.sh + - made jobs.h include a file `endian.h' if NO_WAIT_H is defined. + This file defines either BIG_ENDIAN or LITTLE_ENDIAN, and is + automatically generated by `endian' and `endian.sh'. + +execute_cmd.c + - aa && bb & was being executed incorrectly -- the subshell was + not being forced for the `aa && bb' portion. Same for aa || bb &. + Of course, if the sh `grammar' was regular `aa && bb &' would + be treated the same way as `aa ; bb &'. + +cpp-Makefile, psize.sh, ulimit.c + - changed the `psize' stuff so that ulimit.c includes a file + `pipesize.h', which contains a #define for PIPESIZE. + pipesize.h depends on psize, which is still made via the standard + `make' rules. It's exactly like the `endian' stuff. + +parse.y + - pre_process_line can return NULL, so we have to take that into + account in shell_getc + +glob.c + - fixed glob_pattern_p to only return TRUE for a pattern containing + a `[' if there is at least one `]' to match it. It produces wrong + results if allow_null_glob_expansion is set, and is inefficient + otherwise (wasted calls to glob_filename). + + For instance, if some twisted soul sets allow_null_glob_expansion, + the following would produce an error without this fix: + + if [ a = a ] ; then echo hi ; fi + + 12/16 + ----- +execute_cmd.c, parse.y, shell.h + - the `subshell bit' in the command struct is being used for two + purposes: to signal that the user requested that this command be + done in a subshell via `()' and to force some portions of a + command to be executed in a subshell, like `{ xx } &'. We need + to differentiate between the two so that the command printed when + reporting job status is correct and so the code is clearer. + + Define two `states' for that value, if non-zero: WANT_SUBSHELL is + used when the user requests a subshell, and FORCE_SUBSHELL is used + internally by the command execution code. + +parse.y + - clean up some casts, and make sure function arguments are coerced + to the correct type + +subst.c + - comment out some unnecessary `break' statements in case statement + clauses that immediately follow `goto' statements. It makes the + compilation output cleaner on a compiler that complains about such + things, like the IBM/4.3 compiler (High-C). + +make_cmd.c + - move all the error reporting code to the end of the file, so that + picky compilers that like to report about mismatches in the number + of arguments won't complain about the varargs code. + - it's not allows to pass a va_list from one function to another, so + expand the body of fatal_error to be the same as report_error in + the varargs case + + 12/17 + ----- +readline/readline.c + - Use TCXONC in rl_restart_output, if it's defined. + +make_cmd.c, builtins.c, builtins.c.posix, shell.c + - Make all the non-varargs versions of the various error reporting + functions take 5 arguments + + 12/18 + ----- +builtins.c, builtins.c.posix + - made the builtins that accept option arguments report errors when + they get a bad option, and make these error messages consistent. + The builtins affected are: export, hash, history, read, readonly, + dirs, jobs, declare, typeset, local, and type. + +shell.c + - make the function that displays the version number of the shell + indicate that it's the CWRU version. + +readline/readline.c + - On machines without BSD signals, do a signal(SIGINT, SIG_IGN) in + rl_signal_handler if an interrupt is received. This will take + the place of blocking it while in the handler. + +jobs.c, jobs.c.posix + - change the setting of the job control signals SIGTSTP, SIGTTOU, + and SIGTTIN to SIG_DFL in make_child when job control is not + active + + 12/19 + ----- +builtins.c, builtins.c.posix + - corrected some spelling errors and other mistakes in the help + documentation + +readline/readline.c + - Made the inclusion of sys/ptem.h dependent on the definition of + USGr4 + + 12/20 + ----- +machines.h + - Added -DUSGr4 to SYSDEP_CFLAGS in the System V.4 machines.h entry + for the i386 so it will get passed to readline. + - new entry for Ardent Titan + + 12/22 + ----- +general.c + - added two new functions to print time values in a standard way: + print_timeval, which prints the contents of a struct timeval, + and print_time_in_hz, which prints a time_t scaled by the value + of HZ (which is system-dependent). + +builtins.c, builtins.c.posix + - made times_builtin call the new functions for printing time + + 12/30 + ----- +general.h + - made the definition of `sighandler' as `void' or `int' depend + on the definition of VOID_SIGHANDLER; provide the definition + for those systems already using that code + +machines.h + - new entry for AIX/PS2 1.2 + + 12/31 + ----- +mailcheck.c + - When reporting that a mail file has been read, take into account + changes in the file size as well, and only report the change if + the file has gotten larger.

This is to avoid + an `extra' value of RANDOM, for instance, being `wasted' in the + call to find_variable in make_local_variable + +execute_cmd.c, builtins.c, builtins.c.px, shell.h + - changed the bitmap holding the file descriptors to be closed in + the child to be a structure holding a bitmap and a size, rather + than use a char * bitmap with a fixed size, which will inevitably + be too small. You'd probably run out of processes before you + ran out of file descriptors, though.

If you're using + `csh' on an old version of System V, you might need to type `sh + ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes some time. While running, it prints + messages telling which features it is checking for. + + 2. Type `make' to compile Bash and build the `bashbug' bug reporting + script. + + 3. Optionally, type `make tests' to run the Bash test suite. + + 4. Type `make install' to install `bash' and `bashbug'. This will + also install the manual pages and Info file. + +The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package +(the top directory, the `builtins', `doc', and `support' directories, +each directory under `lib', and several others). It also creates a +`config.h' file containing system-dependent definitions. Finally, it +creates a shell script named `config.status' that you can run in the +future to recreate the current configuration, a file `config.cache' +that saves the results of its tests to speed up reconfiguring, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). If at some point `config.cache' contains +results you don't want to keep, you may remove or edit it. + +To find out more about the options and arguments that the `configure' +script understands, type + + bash-2.04$ ./configure --help + +at the Bash prompt in your Bash source directory. + +If you need to do unusual things to compile Bash, please try to figure +out how `configure' could check whether or not to do them, and mail +diffs or instructions to so they can be +considered for the next release. + +The file `configure.in' is used to create `configure' by a program +called Autoconf. You only need `configure.in' if you want to change it +or regenerate `configure' using a newer version of Autoconf. If you do +this, make sure you are using Autoconf version 2.50 or newer. + +You can remove the program binaries and object files from the source +code directory by typing `make clean'. To also remove the files that +`configure' created (so you can compile Bash for a different kind of +computer), type `make distclean'. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +On systems that have the `env' program, you can do it like this: + + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +The configuration process uses GCC to build Bash if it is available. + +Compiling For Multiple Architectures +==================================== + +You can compile Bash for more than one kind of computer at the same +time, by placing the object files for each architecture in their own +directory. To do this, you must use a version of `make' that supports +the `VPATH' variable, such as GNU `make'. `cd' to the directory where +you want the object files and executables to go and run the `configure' +script from the source directory. You may need to supply the +`--srcdir=PATH' argument to tell `configure' where the source files +are. `configure' automatically checks for the source code in the +directory that `configure' is in and in `..'. + +If you have to use a `make' that does not supports the `VPATH' +variable, you can compile Bash for one architecture at a time in the +source code directory. After you have installed Bash for one +architecture, use `make distclean' before reconfiguring for another +architecture. + +Alternatively, if your system supports symbolic links, you can use the +`support/mkclone' script to create a build tree which has symbolic +links back to each file in the source directory. Here's an example +that creates a build directory in the current directory from a source +directory `/usr/gnu/src/bash-2.0': + + bash /usr/gnu/src/bash-2.0/support/mkclone -s /usr/gnu/src/bash-2.0 . + +The `mkclone' script requires Bash, so you must have already built Bash +for at least one architecture before you can create build directories +for other architectures. + +Installation Names +================== + +By default, `make install' will install into `/usr/local/bin', +`/usr/local/man', etc. You can specify an installation prefix other +than `/usr/local' by giving `configure' the option `--prefix=PATH', or +by specifying a value for the `DESTDIR' `make' variable when running +`make install'. + +You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', `make install' will +use PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + +Specifying the System Type +========================== + +There may be some features `configure' can not figure out +automatically, but need to determine by the type of host Bash will run +on. Usually `configure' can figure that out, but if it prints a +message saying it can not guess the host type, give it the +`--host=TYPE' option. `TYPE' can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: +`CPU-COMPANY-SYSTEM' (e.g., `i386-unknown-freebsd4.2'). + +See the file `support/config.sub' for the possible values of each field. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. `configure' +looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: the Bash `configure' looks for a site script, but not all +`configure' scripts do. + +Operation Controls +================== + +`configure' recognizes the following options to control how it operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. + +`--srcdir=DIR' + Look for the Bash source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely used, boilerplate +options. `configure --help' prints the complete list. + +Optional Features +================= + +The Bash `configure' has a number of `--enable-FEATURE' options, where +FEATURE indicates an optional part of Bash. There are also several +`--with-PACKAGE' options, where PACKAGE is something like `bash-malloc' +or `purify'. To turn off the default use of a package, use +`--without-PACKAGE'. To configure Bash without a feature that is +enabled by default, use `--disable-FEATURE'. + +Here is a complete list of the `--enable-' and `--with-' options that +the Bash `configure' recognizes. + +`--with-afs' + Define if you are using the Andrew File System from Transarc. + +`--with-bash-malloc' + Use the Bash version of `malloc' in the directory `lib/malloc'. + This is not the same `malloc' that appears in GNU libc, but an + older version originally derived from the 4.2 BSD `malloc'. This + `malloc' is very fast, but wastes some space on each allocation. + This option is enabled by default. The `NOTES' file contains a + list of systems for which this should be turned off, and + `configure' disables this option automatically for a number of + systems. + +`--with-curses' + Use the curses library instead of the termcap library. This should + be supplied if your system has an inadequate or incomplete termcap + database. + +`--with-gnu-malloc' + A synonym for `--with-bash-malloc'. + +`--with-installed-readline[=PREFIX]' + Define this to make Bash link with a locally-installed version of + Readline rather than the version in `lib/readline'. This works + only with Readline 5.0 and later versions. If PREFIX is `yes' or + not supplied, `configure' uses the values of the make variables + `includedir' and `libdir', which are subdirectories of `prefix' by + default, to find the installed version of Readline if it is not in + the standard system include and library directories. If PREFIX is + `no', Bash links with the version in `lib/readline'. If PREFIX is + set to any other value, `configure' treats it as a directory + pathname and looks for the installed version of Readline in + subdirectories of that directory (include files in + PREFIX/`include' and the library in PREFIX/`lib'). + +`--with-purify' + Define this to use the Purify memory allocation checker from + Rational Software. + +`--enable-minimal-config' + This produces a shell with minimal features, close to the + historical Bourne shell. + +There are several `--enable-' options that alter how Bash is compiled +and linked, rather than changing run-time features. + +`--enable-largefile' + Enable support for large files + (http://www.sas.com/standards/large_file/x_open.20Mar96.html) if + the operating system requires special compiler options to build + programs which can access large files. This is enabled by + default, if the operating system provides large file support. + +`--enable-profiling' + This builds a Bash binary that produces profiling information to be + processed by `gprof' each time it is executed. + +`--enable-static-link' + This causes Bash to be linked statically, if `gcc' is being used. + This could be used to build a version to use as root's shell. + +The `minimal-config' option can be used to disable all of the following +options, but it is processed first, so individual options may be +enabled using `enable-FEATURE'. + +All of the following options except for `disabled-builtins' and +`xpg-echo-default' are enabled by default, unless the operating system +does not provide the necessary support. + +`--enable-alias' + Allow alias expansion and include the `alias' and `unalias' + builtins (*note Aliases::). + +`--enable-arith-for-command' + Include support for the alternate form of the `for' command that + behaves like the C language `for' statement (*note Looping + Constructs::). + +`--enable-array-variables' + Include support for one-dimensional array shell variables (*note + Arrays::). + +`--enable-bang-history' + Include support for `csh'-like history substitution (*note History + Interaction::). + +`--enable-brace-expansion' + Include `csh'-like brace expansion ( `b{a,b}c' ==> `bac bbc' ). + See *Note Brace Expansion::, for a complete description. + +`--enable-command-timing' + Include support for recognizing `time' as a reserved word and for + displaying timing statistics for the pipeline following `time' + (*note Pipelines::). This allows pipelines as well as shell + builtins and functions to be timed. + +`--enable-cond-command' + Include support for the `[[' conditional command. (*note + Conditional Constructs::). + +`--enable-cond-regexp' + Include support for matching POSIX regular expressions using the + `=~' binary operator in the `[[' conditional command. (*note + Conditional Constructs::). + +`--enable-debugger' + Include support for the bash debugger (distributed separately). + +`--enable-directory-stack' + Include support for a `csh'-like directory stack and the `pushd', + `popd', and `dirs' builtins (*note The Directory Stack::). + +`--enable-disabled-builtins' + Allow builtin commands to be invoked via `builtin xxx' even after + `xxx' has been disabled using `enable -n xxx'. See *Note Bash + Builtins::, for details of the `builtin' and `enable' builtin + commands. + +`--enable-dparen-arithmetic' + Include support for the `((...))' command (*note Conditional + Constructs::). + +`--enable-extended-glob' + Include support for the extended pattern matching features + described above under *Note Pattern Matching::. + +`--enable-help-builtin' + Include the `help' builtin, which displays help on shell builtins + and variables (*note Bash Builtins::). + +`--enable-history' + Include command history and the `fc' and `history' builtin + commands (*note Bash History Facilities::). + +`--enable-job-control' + This enables the job control features (*note Job Control::), if + the operating system supports them. + +`--enable-multibyte' + This enables support for multibyte characters if the operating + system provides the necessary support. + +`--enable-net-redirections' + This enables the special handling of filenames of the form + `/dev/tcp/HOST/PORT' and `/dev/udp/HOST/PORT' when used in + redirections (*note Redirections::). + +`--enable-process-substitution' + This enables process substitution (*note Process Substitution::) if + the operating system provides the necessary support. + +`--enable-progcomp' + Enable the programmable completion facilities (*note Programmable + Completion::). If Readline is not enabled, this option has no + effect. + +`--enable-prompt-string-decoding' + Turn on the interpretation of a number of backslash-escaped + characters in the `$PS1', `$PS2', `$PS3', and `$PS4' prompt + strings. See *Note Printing a Prompt::, for a complete list of + prompt string escape sequences. + +`--enable-readline' + Include support for command-line editing and history with the Bash + version of the Readline library (*note Command Line Editing::). + +`--enable-restricted' + Include support for a "restricted shell". If this is enabled, + Bash, when called as `rbash', enters a restricted mode. See *Note + The Restricted Shell::, for a description of restricted mode. + +`--enable-select' + Include the `select' builtin, which allows the generation of simple + menus (*note Conditional Constructs::). + +`--enable-separate-helpfiles' + Use external files for the documentation displayed by the `help' + builtin instead of storing the text internally. + +`--enable-single-help-strings' + Store the text displayed by the `help' builtin as a single string + for each help topic. This aids in translating the text to + different languages. You may need to disable this if your + compiler cannot handle very long string literals. + +`--enable-strict-posix-default' + Make Bash POSIX-conformant by default (*note Bash POSIX Mode::). + +`--enable-usg-echo-default' + A synonym for `--enable-xpg-echo-default'. + +`--enable-xpg-echo-default' + Make the `echo' builtin expand backslash-escaped characters by + default, without requiring the `-e' option. This sets the default + value of the `xpg_echo' shell option to `on', which makes the Bash + `echo' behave more like the version specified in the Single Unix + Specification, version 3. *Note Bash Builtins::, for a + description of the escape sequences that `echo' recognizes. + +The file `config-top.h' contains C Preprocessor `#define' statements +for options which are not settable from `configure'. Some of these are +not meant to be changed; beware of the consequences if you do. Read +the comments associated with each definition for more information about +its effect. diff --git a/bash-20060316/MANIFEST b/bash-20060316/MANIFEST new file mode 100644 index 000000000..989dbe265

As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. Bash now understands LC_TIME as a special variable so that time display + tracks the current locale. + +b. BASH_ARGC, BASH_ARGV, BASH_SOURCE, and BASH_LINENO are no longer created + as `invisible' variables and may not be unset. + +c. In POSIX mode, if `xpg_echo' option is enabled, the `echo' builtin doesn't + try to interpret any options at all, as POSIX requires. + +d. The `bg' builtin now accepts multiple arguments, as POSIX seems to specify. + +e. Fixed vi-mode word completion and glob expansion to perform tilde + expansion. + +f. The `**' mathematic exponentiation operator is now right-associative. + +g. The `ulimit' builtin has new options: -i (max number of pending signals), + -q (max size of POSIX message queues), and -x (max number of file locks). + +h. A bare `%' once again expands to the current job when used as a job + specifier. + +i. The `+=' assignment operator (append to the value of a string or array) is + now supported for assignment statements and arguments to builtin commands + that accept assignment statements. + +j. BASH_COMMAND now preserves its value when a DEBUG trap is executed. + +k. The `gnu_errfmt' option is enabled automatically if the shell is running + in an emacs terminal window. + +l. New configuration option: --single-help-strings. Causes long help text + to be written as a single string; intended to ease translation. + +m. The COMP_WORDBREAKS variable now causes the list of word break characters + to be emptied when the variable is unset. + +n. An unquoted expansion of $* when $IFS is empty now causes the positional + parameters to be concatenated if the expansion doesn't undergo word + splitting. + +o. Bash now inherits $_ from the environment if it appears there at startup. + +p. New shell option: nocasematch. If non-zero, shell pattern matching ignores + case when used by `case' and `[[' commands. + +q. The `printf' builtin takes a new option: -v var. That causes the output + to be placed into var instead of on stdout. + +r. By default, the shell no longer reports processes dying from SIGPIPE. + +s. Bash now sets the extern variable `environ' to the export environment it + creates, so C library functions that call getenv() (and can't use the + shell-provided replacement) get current values of environment variables. + +t. A new configuration option, `--enable-strict-posix-default', which will + build bash to be POSIX conforming by default. + +u. If compiled for strict POSIX conformance, LINES and COLUMNS may now + override the true terminal size. + +2. New Features in Readline + +a. The key sequence sent by the keypad `delete' key is now automatically + bound to delete-char. + +b. A negative argument to menu-complete now cycles backward through the + completion list. + +c. A new bindable readline variable: bind-tty-special-chars. If non-zero, + readline will bind the terminal special characters to their readline + equivalents when it's called (on by default). + +d. New bindable command: vi-rubout. Saves deleted text for possible + reinsertion, as with any vi-mode `text modification' command; `X' is bound + to this in vi command mode. + +e. A new external application-controllable variable that allows the LINES + and COLUMNS environment variables to set the window size regardless of + what the kernel returns: rl_prefer_env_winsize + +------------------------------------------------------------------------------- +This is a terse description of the new features added to bash-3.0 since +the release of bash-2.05b. As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. ANSI string expansion now implements the \x{hexdigits} escape. + +b. There is a new loadable `strftime' builtin. + +c. New variable, COMP_WORDBREAKS, which controls the readline completer's + idea of word break characters. + +d. The `type' builtin no longer reports on aliases unless alias expansion + will actually be performed. + +e. HISTCONTROL is now a colon-separated list of values, which permits + more extensibility and backwards compatibility. + +f. HISTCONTROL may now include the `erasedups' option, which causes all lines + matching a line being added to be removed from the history list. + +g. `configure' has a new `--enable-multibyte' argument that permits multibyte + character support to be disabled even on systems that support it. + +h. New variables to support the bash debugger: BASH_ARGC, BASH_ARGV, + BASH_SOURCE, BASH_LINENO, BASH_SUBSHELL, BASH_EXECUTION_STRING, + BASH_COMMAND + +i. FUNCNAME has been changed to support the debugger: it's now an array + variable. + +j. for, case, select, arithmetic commands now keep line number information + for the debugger. + +k. There is a new `RETURN' trap executed when a function or sourced script + returns (not inherited child processes; inherited by command substitution + if function tracing is enabled and the debugger is active). + +l. New invocation option: --debugger. Enables debugging and turns on new + `extdebug' shell option. + +m. New `functrace' and `errtrace' options to `set -o' cause DEBUG and ERR + traps, respectively, to be inherited by shell functions. Equivalent to + `set -T' and `set -E' respectively. The `functrace' option also controls + whether or not the DEBUG trap is inherited by sourced scripts. + +n. The DEBUG trap is run before binding the variable and running the action + list in a `for' command, binding the selection variable and running the + query in a `select' command, and before attempting a match in a `case' + command. + +o. New `--enable-debugger' option to `configure' to compile in the debugger + support code. + +p. `declare -F' now prints out extra line number and source file information + if the `extdebug' option is set. + +q. If `extdebug' is enabled, a non-zero return value from a DEBUG trap causes + the next command to be skipped, and a return value of 2 while in a + function or sourced script forces a `return'. + +r. New `caller' builtin to provide a call stack for the bash debugger. + +s. The DEBUG trap is run just before the first command in a function body is + executed, for the debugger. + +t. `for', `select', and `case' command heads are printed when `set -x' is + enabled. + +u. There is a new {x..y} brace expansion, which is shorthand for {x.x+1, + x+2,...,y}. x and y can be integers or single characters; the sequence + may ascend or descend; the increment is always 1. + +v. New ksh93-like ${!array[@]} expansion, expands to all the keys (indices) + of array. + +w. New `force_fignore' shopt option; if enabled, suffixes specified by + FIGNORE cause words to be ignored when performing word completion even + if they're the only possibilities. + +x. New `gnu_errfmt' shopt option; if enabled, error messages follow the `gnu + style' (filename:lineno:message) format. + +y. New `-o bashdefault' option to complete and compgen; if set, causes the + whole set of bash completions to be performed if the compspec doesn't + result in a match. + +z. New `-o plusdirs' option to complete and compgen; if set, causes directory + name completion to be performed and the results added to the rest of the + possible completions. + +aa. `kill' is available as a builtin even when the shell is built without + job control. + +bb. New HISTTIMEFORMAT variable; value is a format string to pass to + strftime(3). If set and not null, the `history' builtin prints out + timestamp information according to the specified format when displaying + history entries. If set, bash tells the history library to write out + timestamp information when the history file is written. + +cc. The [[ ... ]] command has a new binary `=~' operator that performs + extended regular expression (egrep-like) matching. + +dd. `configure' has a new `--enable-cond-regexp' option (enabled by default) + to enable the =~ operator and regexp matching in [[ ... ]]. + +ee. Subexpressions matched by the =~ operator are placed in the new + BASH_REMATCH array variable. + +ff. New `failglob' option that causes an expansion error when pathname + expansion fails to produce a match. + +gg. New `set -o pipefail' option that causes a pipeline to return a failure + status if any of the processes in the pipeline fail, not just the last + one. + +hh. printf builtin understands two new escape sequences: \" and \?. + +ii. `echo -e' understands two new escape sequences: \" and \?. + +jj. The GNU `gettext' package and libintl have been integrated; the shell's + messages can be translated into different languages. + +kk. The `\W' prompt expansion now abbreviates $HOME as `~', like `\w'. + +ll. The error message printed when bash cannot open a shell script supplied + as argument 1 now includes the name of the shell, to better identify + the error as coming from bash. + +mm. The parameter pattern removal and substitution expansions are now much + faster and more efficient when using multibyte characters. + +nn. The `jobs', `kill', and `wait' builtins now accept job control notation + even if job control is not enabled. + +oo. The historical behavior of `trap' that allows a missing `action' argument + to cause each specified signal's handling to be reset to its default is + now only supported when `trap' is given a single non-option argument. + +2. New Features in Readline + +a. History expansion has a new `a' modifier equivalent to the `g' modifier + for compatibility with the BSD csh. + +b. History expansion has a new `G' modifier equivalent to the BSD csh `g' + modifier, which performs a substitution once per word. + +c. All non-incremental search operations may now undo the operation of + replacing the current line with the history line. + +d. The text inserted by an `a' command in vi mode can be reinserted with + `.'. + +e. New bindable variable, `show-all-if-unmodified'. If set, the readline + completer will list possible completions immediately if there is more + than one completion and partial completion cannot be performed. + +f. There is a new application-callable `free_history_entry()' function. + +g. History list entries now contain timestamp information; the history file + functions know how to read and write timestamp information associated + with each entry. + +h. Four new key binding functions have been added: + + rl_bind_key_if_unbound() + rl_bind_key_if_unbound_in_map() + rl_bind_keyseq_if_unbound() + rl_bind_keyseq_if_unbound_in_map() + +i. New application variable, rl_completion_quote_character, set to any + quote character readline finds before it calls the application completion + function. + +j. New application variable, rl_completion_suppress_quote, settable by an + application completion function. If set to non-zero, readline does not + attempt to append a closing quote to a completed word. + +k. New application variable, rl_completion_found_quote, set to a non-zero + value if readline determines that the word to be completed is quoted. + Set before readline calls any application completion function. + +l. New function hook, rl_completion_word_break_hook, called when readline + needs to break a line into words when completion is attempted. Allows + the word break characters to vary based on position in the line. + +m. New bindable command: unix-filename-rubout. Does the same thing as + unix-word-rubout, but adds `/' to the set of word delimiters. + +n. When listing completions, directories have a `/' appended if the + `mark-directories' option has been enabled. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to bash-2.05b since +the release of bash-2.05a. As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. If set, TMOUT is the default timeout for the `read' builtin. + +b. `type' has two new options: `-f' suppresses shell function lookup, and + `-P' forces a $PATH search. + +c. New code to handle multibyte characters. + +d. `select' was changed to be more ksh-compatible, in that the menu is + reprinted each time through the loop only if REPLY is set to NULL. + The previous behavior is available as a compile-time option. + +e. `complete -d' and `complete -o dirnames' now force a slash to be + appended to names which are symlinks to directories. + +f. There is now a bindable edit-and-execute-command readline command, + like the vi-mode `v' command, bound to C-xC-e in emacs mode. + +g. Added support for ksh93-like [:word:] character class in pattern matching. + +h. The $'...' quoting construct now expands \cX to Control-X. + +i. A new \D{...} prompt expansion; passes the `...' to strftime and inserts + the result into the expanded prompt. + +j. The shell now performs arithmetic in the largest integer size the + machine supports (intmax_t), instead of long. + +k. If a numeric argument is supplied to one of the bash globbing completion + functions, a `*' is appended to the word before expansion is attempted. + +l. The bash globbing completion functions now allow completions to be listed + with double tabs or if `show-all-if-ambiguous' is set. + +m. New `-o nospace' option for `complete' and `compgen' builtins; suppresses + readline's appending a space to the completed word. + +n. New `here-string' redirection operator: <<< word. + +o. When displaying variables, function attributes and definitions are shown + separately, allowing them to be re-used as input (attempting to re-use + the old output would result in syntax errors). + +p. There is a new configuration option `--enable-mem-scramble', controls + bash malloc behavior of writing garbage characters into memory at + allocation and free time. + +q. The `complete' and `compgen' builtins now have a new `-s/-A service' + option to complete on names from /etc/services. + +r. `read' has a new `-u fd' option to read from a specified file descriptor. + +s. Fix the completion code so that expansion errors in a directory name + don't cause a longjmp back to the command loop. + +t. Fixed word completion inside command substitution to work a little more + intuitively. + +u. The `printf' %q format specifier now uses $'...' quoting to print the + argument if it contains non-printing characters. + +v. The `declare' and `typeset' builtins have a new `-t' option. When applied + to functions, it causes the DEBUG trap to be inherited by the named + function. Currently has no effect on variables. + +w. The DEBUG trap is now run *before* simple commands, ((...)) commands, + [[...]] conditional commands, and for ((...)) loops. + +x. The expansion of $LINENO inside a shell function is only relative to the + function start if the shell is interactive -- if the shell is running a + script, $LINENO expands to the line number in the script. This is as + POSIX-2001 requires. + +y. The bash debugger in examples/bashdb has been modified to work with the + new DEBUG trap semantics, the command set has been made more gdb-like, + and the changes to $LINENO make debugging functions work better. Code + from Gary Vaughan. + +z. New [n]<&word- and [n]>&word- redirections from ksh93 -- move fds (dup + and close). + +aa. There is a new `-l' invocation option, equivalent to `--login'. + +bb. The `hash' builtin has a new `-l' option to list contents in a reusable + format, and a `-d' option to remove a name from the hash table. + +cc. There is now support for placing the long help text into separate files + installed into ${datadir}/bash. Not enabled by default; can be turned + on with `--enable-separate-helpfiles' option to configure. + +dd. All builtins that take operands accept a `--' pseudo-option, except + `echo'. + +ee. The `echo' builtin now accepts \0xxx (zero to three octal digits following + the `0') in addition to \xxx (one to three octal digits) for SUSv3/XPG6/ + POSIX.1-2001 compliance. + + +2. New Features in Readline + +a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both + be bound to readline functions. Now the arrow keys may be used in vi + insert mode. + +b. When listing completions, and the number of lines displayed is more than + the screen length, readline uses an internal pager to display the results. + This is controlled by the `page-completions' variable (default on). + +c. New code to handle editing and displaying multibyte characters. + +d. The behavior introduced in bash-2.05a of deciding whether or not to + append a slash to a completed name that is a symlink to a directory has + been made optional, controlled by the `mark-symlinked-directories' + variable (default is the 2.05a behavior). + +e. The `insert-comment' command now acts as a toggle if given a numeric + argument: if the first characters on the line don't specify a + comment, insert one; if they do, delete the comment text + +f. New application-settable completion variable: + rl_completion_mark_symlink_dirs, allows an application's completion + function to temporarily override the user's preference for appending + slashes to names which are symlinks to directories. + +g. New function available to application completion functions: + rl_completion_mode, to tell how the completion function was invoked + and decide which argument to supply to rl_complete_internal (to list + completions, etc.). + +h. Readline now has an overwrite mode, toggled by the `overwrite-mode' + bindable command, which could be bound to `Insert'. + +i. New application-settable completion variable: + rl_completion_suppress_append, inhibits appending of + rl_completion_append_character to completed words. + +j. New key bindings when reading an incremental search string: ^W yanks + the currently-matched word out of the current line into the search + string; ^Y yanks the rest of the current line into the search string, + DEL or ^H deletes characters from the search string. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to bash-2.05a since +the release of bash-2.05. As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. Added support for DESTDIR installation root prefix, so you can do a + `make install DESTDIR=bash-root' and do easier binary packaging. + +b. Added support for builtin printf "'" flag character as per latest POSIX + drafts. + +c. Support for POSIX.2 printf(1) length specifiers `j', `t', and `z' (from + ISO C99). + +d. New autoconf macro, RL_LIB_READLINE_VERSION, for use by other applications + (bash doesn't use very much of what it returns). + +e. `set [-+]o nolog' is recognized as required by the latest POSIX drafts, + but ignored. + +f. New read-only `shopt' option: login_shell. Set to non-zero value if the + shell is a login shell. + +g. New `\A' prompt string escape sequence; expands to time in 24 HH:MM format. + +h. New `-A group/-g' option to complete and compgen; does group name + completion. + +i. New `-t' option to `hash' to list hash values for each filename argument. + +j. New [-+]O invocation option to set and unset `shopt' options at startup. + +k. configure's `--with-installed-readline' option now takes an optional + `=PATH' suffix to set the root of the tree where readline is installed + to PATH. + +l. The ksh-like `ERR' trap has been added. The `ERR' trap will be run + whenever the shell would have exited if the -e option were enabled. + It is not inherited by shell functions. + +m. `readonly', `export', and `declare' now print variables which have been + given attributes but not set by assigning a value as just a command and + a variable name (like `export foo') when listing, as the latest POSIX + drafts require. + +n. `bashbug' now requires that the subject be changed from the default. + +o. configure has a new `--enable-largefile' option, like other GNU utilities. + +p. `for' loops now allow empty word lists after `in', like the latest POSIX + drafts require. + +q. The builtin `ulimit' now takes two new non-numeric arguments: `hard', + meaning the current hard limit, and `soft', meaning the current soft + limit, in addition to `unlimited' + +r. `ulimit' now prints the option letter associated with a particular + resource when printing more than one limit. + +s. `ulimit' prints `hard' or `soft' when a value is not `unlimited' but is + one of RLIM_SAVED_MAX or RLIM_SAVED_CUR, respectively. + +t. The `printf' builtin now handles the %a and %A conversions if they're + implemented by printf(3). + +u. The `printf' builtin now handles the %F conversion (just about like %f). + +v. The `printf' builtin now handles the %n conversion like printf(3). The + corresponding argument is the name of a shell variable to which the + value is assigned. + +2. New Features in Readline + +a. Added extern declaration for rl_get_termcap to readline.h, making it a + public function (it was always there, just not in readline.h). + +b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402, + RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2. + +c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION. + +d. New bindable boolean readline variable: match-hidden-files. Controls + completion of files beginning with a `.' (on Unix). Enabled by default. + +e. The history expansion code now allows any character to terminate a + `:first-' modifier, like csh. + +f. New bindable variable `history-preserve-point'. If set, the history + code attempts to place the user at the same location on each history + line retrived with previous-history or next-history. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to bash-2.05 since +the release of bash-2.04. As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. Added a new `--init-file' invocation argument as a synonym for `--rcfile', + per the new GNU coding standards. + +b. The /dev/tcp and /dev/udp redirections now accept service names as well as + port numbers. + +c. `complete' and `compgen' now take a `-o value' option, which controls some + of the aspects of that compspec. Valid values are: + + default - perform bash default completion if programmable + completion produces no matches + dirnames - perform directory name completion if programmable + completion produces no matches + filenames - tell readline that the compspec produces filenames, + so it can do things like append slashes to + directory names and suppress trailing spaces + +d. A new loadable builtin, realpath, which canonicalizes and expands symlinks + in pathname arguments. + +e. When `set' is called without options, it prints function defintions in a + way that allows them to be reused as input. This affects `declare' and + `declare -p' as well. This only happens when the shell is not in POSIX + mode, since POSIX.2 forbids this behavior. + +f. Bash-2.05 once again honors the current locale setting when processing + ranges within pattern matching bracket expressions (e.g., [A-Z]). + +2. New Features in Readline + +a. The blink timeout for paren matching is now settable by applications, + via the rl_set_paren_blink_timeout() function. + +b. _rl_executing_macro has been renamed to rl_executing_macro, which means + it's now part of the public interface. + +c. Readline has a new variable, rl_readline_state, which is a bitmap that + encapsulates the current state of the library; intended for use by + callbacks and hook functions. + +d. New application-callable function rl_set_prompt(const char *prompt): + expands its prompt string argument and sets rl_prompt to the result. + +e. New application-callable function rl_set_screen_size(int rows, int cols): + public method for applications to set readline's idea of the screen + dimensions. + +f. New function, rl_get_screen_size (int *rows, int *columns), returns + readline's idea of the screen dimensions. + +g. The timeout in rl_gather_tyi (readline keyboard input polling function) + is now settable via a function (rl_set_keyboard_input_timeout()). + +h. Renamed the max_input_history variable to history_max_entries; the old + variable is maintained for backwards compatibility. + +i. The list of characters that separate words for the history tokenizer is + now settable with a variable: history_word_delimiters. The default + value is as before. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to bash-2.04 since +the release of bash-2.03. As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. The history builtin has a `-d offset' option to delete the history entry + at position `offset'. + +b. The prompt expansion code has two new escape sequences: \j, the number of + active jobs; and \l, the basename of the shell's tty device name. + +c. The `bind' builtin has a new `-x' option to bind key sequences to shell + commands. + +d. There is a new shell option, no_empty_command_completion, which, when + enabled, disables command completion when TAB is typed on an empty line. + +e. The `help' builtin has a `-s' option to just print a builtin's usage + synopsis. + +f. There are several new arithmetic operators: id++, id-- (variable + post-increment/decrement), ++id, --id (variable pre-increment/decrement), + expr1 , expr2 (comma operator). + +g. There is a new ksh-93 style arithmetic for command: + for ((expr1 ; expr2; expr3 )); do list; done + +h. The `read' builtin has a number of new options: + -t timeout only wait timeout seconds for input + -n nchars only read nchars from input instead of a full line + -d delim read until delim rather than newline + -s don't echo input chars as they are read + +i. The redirection code now handles several filenames specially: + /dev/fd/N, /dev/stdin, /dev/stdout, and /dev/stderr, whether or + not they are present in the file system. + +j. The redirection code now recognizes pathnames of the form + /dev/tcp/host/port and /dev/udp/host/port, and tries to open a socket + of the appropriate type to the specified port on the specified host. + +k. The ksh-93 ${!prefix*} expansion, which expands to the names of all + shell variables with prefix PREFIX, has been implemented. + +l. There is a new dynamic variable, FUNCNAME, which expands to the name of + a currently-executing function. Assignments to FUNCNAME have no effect. + +m. The GROUPS variable is no longer readonly; assignments to it are silently + discarded. This means it can be unset. + +n. A new programmable completion facility, with two new builtin commands: + complete and compgen. + +o. configure has a new option, `--enable-progcomp', to compile in the + programmable completion features (enabled by default). + +p. `shopt' has a new option, `progcomp', to enable and disable programmable + completion at runtime. + +q. Unsetting HOSTFILE now clears the list of hostnames used for completion. + +r. configure has a new option, `--enable-bash-malloc', replacing the old + `--with-gnu-malloc' (which is still present for backwards compatibility). + +s. There is a new manual page describing rbash, the restricted shell. + +t. `bashbug' has new `--help' and `--version' options. + +u. `shopt' has a new `xpg_echo' option, which controls the behavior of + `echo' with respect to backslash-escaped characters at runtime. + +v. If NON_INTERACTIVE_LOGIN_SHELLS is defined, all login shells read the + startup files, even if they are not interactive. + +w. The LC_NUMERIC variable is now treated specially, and used to set the + LC_NUMERIC locale category for number formatting, e.g., when `printf' + displays floating-point numbers. + +2. New features in Readline + +a. Parentheses matching is now always compiled into readline, and enabled + or disabled when the value of the `blink-matching-paren' variable is + changed. + +b. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename. + +c. MS-DOS systems now use ~/_history as the default history file. + +d. history-search-{forward,backward} now leave the point at the end of the + line when the string to search for is empty, like + {reverse,forward}-search-history. + +e. history-search-{forward,backward} now leave the last history line found + in the readline buffer if the second or subsequent search fails. + +f. New function for use by applications: rl_on_new_line_with_prompt, used + when an application displays the prompt itself before calling readline(). + +g. New variable for use by applications: rl_already_prompted. An application + that displays the prompt itself before calling readline() must set this to + a non-zero value. + +h. A new variable, rl_gnu_readline_p, always 1. The intent is that an + application can verify whether or not it is linked with the `real' + readline library or some substitute. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to bash-2.03 since +the release of bash-2.02. As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. New `shopt' option, `restricted_shell', indicating whether or not the + shell was started in restricted mode, for use in startup files. + +b. Filename generation is now performed on the words between ( and ) in + array assignments (which it probably should have done all along). + +c. OLDPWD is now auto-exported, as POSIX.2 seems to require. + +d. ENV and BASH_ENV are read-only variables in a restricted shell. + +e. A change was made to the startup file code so that any shell begun with + the `--login' option, even non-interactive shells, will source the login + shell startup files. + +2. New Features in Readline + +a. Many changes to the signal handling: + o Readline now catches SIGQUIT and cleans up the tty before returning; + o A new variable, rl_catch_signals, is available to application writers + to indicate to readline whether or not it should install its own + signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP, + SIGTTIN, and SIGTTOU; + o A new variable, rl_catch_sigwinch, is available to application + writers to indicate to readline whether or not it should install its + own signal handler for SIGWINCH, which will chain to the calling + applications's SIGWINCH handler, if one is installed; + o There is a new function, rl_free_line_state, for application signal + handlers to call to free up the state associated with the current + line after receiving a signal; + o There is a new function, rl_cleanup_after_signal, to clean up the + display and terminal state after receiving a signal; + o There is a new function, rl_reset_after_signal, to reinitialize the + terminal and display state after an application signal handler + returns and readline continues + +b. There is a new function, rl_resize_terminal, to reset readline's idea of + the screen size after a SIGWINCH. + +c. New public functions: rl_save_prompt and rl_restore_prompt. These were + previously private functions with a `_' prefix. + +d. New function hook: rl_pre_input_hook, called just before readline starts + reading input, after initialization. + +e. New function hook: rl_display_matches_hook, called when readline would + display the list of completion matches. The new function + rl_display_match_list is what readline uses internally, and is available + for use by application functions called via this hook. + +f. New bindable function, delete-char-or-list, like tcsh. + +g. A new variable, rl_erase_empty_line, which, if set by an application using + readline, will cause readline to erase, prompt and all, lines on which the + only thing typed was a newline. + +h. New bindable variable: `isearch-terminators'. + +i. New bindable function: `forward-backward-delete-char' (unbound by default). + +------------------------------------------------------------------------------- +This is a terse description of the new features added to bash-2.02 since +the release of bash-2.01.1. As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. A new version of malloc, based on the older GNU malloc, that has many + changes, is more page-based, is more conservative with memory usage, + and does not `orphan' large blocks when they are freed. + +b. A new version of gmalloc, based on the old GLIBC malloc, with many + changes and range checking included by default. + +c. A new implementation of fnmatch(3) that includes full POSIX.2 Basic + Regular Expression matching, including character classes, collating + symbols, equivalence classes, and support for case-insensitive pattern + matching. + +d. ksh-88 egrep-style extended pattern matching ([@+*?!](patlist)) has been + implemented, controlled by a new `shopt' option, `extglob'. + +e. There is a new ksh-like `[[' compound command, which implements + extended `test' functionality. + +f. There is a new `printf' builtin, implemented according to the POSIX.2 + specification. + +g. There is a new feature for command substitution: $(< filename) now expands + to the contents of `filename', with any trailing newlines removed + (equivalent to $(cat filename)). + +h. There are new tilde prefixes which expand to directories from the + directory stack. + +i. There is a new `**' arithmetic operator to do exponentiation. + +j. There are new configuration options to control how bash is linked: + `--enable-profiling', to allow bash to be profiled with gprof, and + `--enable-static-link', to allow bash to be linked statically. + +k. There is a new configuration option, `--enable-cond-command', which + controls whether or not the `[[' command is included. It is on by + default. + +l. There is a new configuration option, `--enable-extended-glob', which + controls whether or not the ksh extended globbing feature is included. + It is enabled by default. + +m. There is a new configuration #define in config.h.top that, when enabled, + will cause all login shells to source /etc/profile and one of the user- + specific login shell startup files, whether or not the shell is + interactive. + +n. There is a new invocation option, `--dump-po-strings', to dump + a shell script's translatable strings ($"...") in GNU `po' format. + +o. There is a new `shopt' option, `nocaseglob', to enable case-insensitive + pattern matching when globbing filenames and using the `case' construct. + +p. There is a new `shopt' option, `huponexit', which, when enabled, causes + the shell to send SIGHUP to all jobs when an interactive login shell + exits. + +q. `bind' has a new `-u' option, which takes a readline function name as an + argument and unbinds all key sequences bound to that function in a + specified keymap. + +r. `disown' now has `-a' and `-r' options, to limit operation to all jobs + and running jobs, respectively. + +s. The `shopt' `-p' option now causes output to be displayed in a reusable + format. + +t. `test' has a new `-N' option, which returns true if the filename argument + has been modified since it was last accessed. + +u. `umask' now has a `-p' option to print output in a reusable format. + +v. A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...' + translation code. It expands to the character whose ascii code is NNN + in hexadecimal. + +w. The prompt string expansion code has a new `\r' escape sequence. + +x. The shell may now be cross-compiled for the CYGWIN32 environment on + a Unix machine. + +2. New Features in Readline + +a. There is now an option for `iterative' yank-last-arg handline, so a user + can keep entering `M-.', yanking the last argument of successive history + lines. + +b. New variable, `print-completions-horizontally', which causes completion + matches to be displayed across the screen (like `ls -x') rather than up + and down the screen (like `ls'). + +c. New variable, `completion-ignore-case', which causes filename completion + and matching to be performed case-insensitively. + +d. There is a new bindable command, `magic-space', which causes history + expansion to be performed on the current readline buffer and a space to + be inserted into the result. + +e. There is a new bindable command, `menu-complete', which enables tcsh-like + menu completion (successive executions of menu-complete insert a single + completion match, cycling through the list of possible completions). + +f. There is a new bindable command, `paste-from-clipboard', for use on Win32 + systems, to insert the text from the Win32 clipboard into the editing + buffer. + +g. The key sequence translation code now understands printf-style backslash + escape sequences, including \NNN octal escapes. These escape sequences + may be used in key sequence definitions or macro values. + +h. An `$include' inputrc file parser directive has been added. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to bash-2.01 since +the release of bash-2.0. As always, the manual page (doc/bash.1) is the +place to look for complete descriptions. + +1. New Features in Bash + +a. There is a new builtin array variable: GROUPS, the set of groups to which + the user belongs. This is used by the test suite. + +2. New Features in Readline + +a. If a key sequence bound to `universal-argument' is read while reading a + numeric argument started with `universal-argument', it terminates the + argument but is otherwise ignored. This provides a way to insert multiple + instances of a digit string, and is how GNU emacs does it. + +------------------------------------------------------------------------------- +This is a terse description of the new features added to bash-2.0 since +the release of bash-1.14.7. As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. There is a new invocation option, -D, that dumps translatable strings + in a script. + +b. The `long' invocation options must now be prefixed with `--'. + +c. New long invocation options: --dump-strings, --help, --verbose + +d. The `nolineediting' invocation option was renamed to `noediting'. + +e. The `nobraceexpansion' and `quiet' long invocation options were removed. + +f. The `--help' and `--version' long options now work as the GNU coding + standards specify. + +g. If invoked as `sh', bash now enters posix mode after reading the + startup files, and reads and executes commands from the file named + by $ENV if interactive (as POSIX.2 specifies). A login shell invoked + as `sh' reads $ENV after /etc/profile and ~/.profile. + +h. There is a new reserved word, `time', for timing pipelines, builtin + commands, and shell functions. It uses the value of the TIMEFORMAT + variable as a format string describing how to print the timing + statistics. + +i. The $'...' quoting syntax expands ANSI-C escapes in ... and leaves the + result single-quoted. + +j. The $"..." quoting syntax performs locale-specific translation of ... + and leaves the result double-quoted. + +k. LINENO now works correctly in functions. + +l. New variables: DIRSTACK, PIPESTATUS, BASH_VERSINFO, HOSTNAME, SHELLOPTS, + MACHTYPE. The first three are array variables. + +m. The BASH_VERSION and BASH_VERSINFO variables now include the shell's + `release status' (alpha[N], beta[N], release). + +n. Some variables have been removed: MAIL_WARNING, notify, history_control, + command_oriented_history, glob_dot_filenames, allow_null_glob_expansion, + nolinks, hostname_completion_file, noclobber, no_exit_on_failed_exec, and + cdable_vars. Most of them are now implemented with the new `shopt' + builtin; others were already implemented by `set'. + +o. Bash now uses some new variables: LC_ALL, LC_MESSAGES, LC_CTYPE, + LC_COLLATE, LANG, GLOBIGNORE, HISTIGNORE. + +p. The shell now supports integer-indexed arrays of unlimited length, + with a new compound assignment syntax and changes to the appropriate + builtin commands (declare/typeset, read, readonly, etc.). The array + index may be an arithmetic expression. + +q. ${!var}: indirect variable expansion, equivalent to eval \${$var}. + +r. ${paramter:offset[:length]}: variable substring extraction. + +s. ${parameter/pattern[/[/]string]}: variable pattern substitution. + +t. The $[...] arithmetic expansion syntax is no longer supported, in + favor of $((...)). + +u. Aliases can now be expanded in shell scripts with a shell option + (shopt expand_aliases). + +v. History and history expansion can now be used in scripts with + set -o history and set -H. + +w. All builtins now return an exit status of 2 for incorrect usage. + +x. Interactive shells resend SIGHUP to all running or stopped children + if (and only if) they exit due to a SIGHUP. + +y. New prompting expansions: \a, \e, \H, \T, \@, \v, \V. + +z. Variable expansion in prompt strings is now controllable via a shell + option (shopt promptvars). + +aa. Bash now defaults to using command-oriented history. + +bb. The history file ($HISTFILE) is now truncated to $HISTFILESIZE after + being written. + +cc. The POSIX.2 conditional arithmetic evaluation syntax (expr ? expr : expr) + has been implemented. + +dd. Each builtin now accepts `--' to signify the end of the options, except + as documented (echo, etc.). + +ee. All builtins use -p to display values in a re-readable format where + appropriate, except as documented (echo, type, etc.). + +ff. The `alias' builtin has a new -p option. + +gg. Changes to the `bind' builtin: + o has new options: -psPSVr. + o the `-d' option was renamed to `-p' + o the `-v' option now dumps variables; the old `-v' is now `-P' + +hh. The `bye' synonym for `exit' was removed. + +ii. The -L and -P options to `cd' and `pwd' have been documented. + +jj. The `cd' builtin now does spelling correction on the directory name + by default. This is settable with a shell option (shopt cdspell). + +kk. The `declare' builtin has new options: -a, -F, -p. + +ll. The `dirs' builtin has new options: -c, -p, -v. + +mm. The new `disown' builtin removes jobs from the shell's jobs table + or inhibits the resending of SIGHUP when the shell receives a + SIGHUP. + +nn. The `echo' builtin has a new escape character: \e. + +oo. The `enable' builtin can now load new builtins dynamically from shared + objects on systems with the dlopen/dlsym interface. There are a number + of examples in the examples/loadables directory. There are also + new options: -d, -f, -s, -p. + +pp. The `-all' option to `enable' was removed in favor of `-a'. + +qq. The `exec' builtin has new options: -l, -c, -a. + +rr. The `hash' builtin has a new option: -p. + +ss. The `history' builtin has new options: -c, -p, -s. + +tt. The `jobs' builtin has new options: -r, -s. + +uu. The `kill' builtin has new options: -n signum, -l signame. + +vv. The `pushd' and `popd' builtins have a new option: -n. + +ww. The `read' builtin has new options: -p prompt, -e, -a. + +xx. The `readonly' builtin has a new -a option, and the -n option was removed. + +yy. Changes to the `set' builtin: + o new options: -B, -o keyword, -o onecmd, -o history + o options removed: -l, -d, -o nohash + o options changed: +o, -h, -o hashall + o now displays variables in a format that can be re-read as input + +zz. The new `shopt' builtin controls shell optional behavior previously + done by setting and unsetting certain shell variables. + +aaa. The `test' builtin has new operators: -o option, s1 == s2, s1 < s2, + and s1 > s2, where s1 and s2 are strings. + +bbb. There is a new trap, DEBUG, executed after every simple command. + +ccc. The `trap' builtin has a new -p option. + +ddd. The `ulimit' builtin has a new -l option on 4.4BSD-based systems. + +eee. The PS1, PS2, PATH, and IFS variables may now be unset. + +fff. The restricted shell mode has been expanded and is now documented. + +ggg. Security improvements: + o functions are not imported from the environment if running setuid + or with -p + o no startup files are sourced if running setuid or with -p + +hhh. The documentation has been overhauled: the texinfo manual was + expanded, and HTML versions of the man page and texinfo manual + are included. + +iii. Changes to Posix mode: + o Command lookup now finds special builtins before shell functions. + o Failure of a special builtin causes a non-interactive shell to + exit. Failures are defined in the POSIX.2 specification. + o If the `cd' builtin finds a directory to change to using $CDPATH, + the value assigned to PWD when `cd' completes does not contain + any symbolic links. + o A non-interactive shell exits if a variable assignment error + occurs when no command name follows the assignment statements. + o A non-interactive shell exits if the interation variable in a + `for' statement or the selection variable in a `select' statement + is read-only or another variable assignment error occurs. + o The `<>' redirection operator now opens a file for both stdin and + stdout by default, not just when in posix mode. + o Assignment statements preceding special builtins now persist in + the shell's environment when the builtin completes. + + Posix mode is now completely POSIX.2-compliant (modulo bugs). When + invoked as sh, bash should be completely POSIX.2-compliant. + +jjj. The default value of PS1 is now "\s-\v\$ ". + +kkk. The ksh-like ((...)) arithmetic command syntax has been implemented. + This is exactly equivalent to `let "..."'. + +lll. Integer constants have been extended to base 64. + +mmm. The `ulimit' builtin now sets both hard and soft limits and reports the + soft limit by default. + +2. New Features in Readline + +a. New variables: enable-keypad, input-meta (new name for meta-flag), + mark-directories, visible-stats (now documented), disable-completion, + comment-begin. + +b. New bindable commands: kill-region, copy-region-as-kill, + copy-backward-word, copy-forward-word, set-mark, exchange-point-and-mark, + character-search, character-search-backward, insert-comment, + glob-expand-word, glob-list-expansions, dump-variables, dump-macros. + +c. New emacs keybindings: delete-horizontal-space (M-\), + insert-completions (M-*), possible-completions (M-=). + +d. The history-search-backward and history-search-forward commands were + modified to be the same as previous-line and next-line if point is at + the start of the line. + +e. More file types are available for the visible-stats mode. + +3. Changes of interest in the Bash implementation + +a. There is a new autoconf-based configuration mechanism. + +b. More things have been moved from Posix mode to standard shell behavior. + +c. The trace output (set -x) now inserts quotes where necessary so it can + be reused as input. + +d. There is a compile-time option for a system-wide interactive shell + startup file (disabled by default). + +e. The YACC grammar is smaller and tighter, and all 66 shift-reduce + conflicts are gone. Several parsing bugs have been fixed. + +f. Builtin option parsing has been regularized (using internal_getopt()), + with the exception of `echo', `type', and `set'. + +g. Builtins now return standard usage messages constructed from the + `short doc' used by the help builtin. + +h. Completion now quotes using backslashes by default, but honors + user-supplied quotes. + +i. The GNU libc malloc is available as a configure-time option. + +j. There are more internationalization features; bash uses gettext if + it is available. The $"..." translation syntax uses the current + locale and gettext. + +k. There is better reporting of job termination when the shell is not + interactive. + +l. The shell is somewhat more efficient: it uses a little less memory and + makes fewer system calls. + +4. Changes of interest in the Readline implementation + +a. There is now support for readline `callback' functions. + +b. There is now support for user-supplied input, redisplay, and terminal + preparation functions. + +c. Most of the shell-specific code in readline has been generalized or + removed. + +d. Most of the annoying redisplay bugs have been fixed, notably the problems + with incremental search and excessive redrawing when special characters + appear in the prompt string. + +e. There are new library functions and variables available to application + writers, most having to do with completion and quoting. + +f. The NEWLINE character (^J) is now treated as a search terminator by the + incremental search functions. diff --git a/bash-20060316/NOTES b/bash-20060316/NOTES new file mode 100644 index 000000000..c523752fe --- /dev/null +++ b/bash-20060316/NOTES @@ -0,0 +1,333 @@ +Platform-Specific Configuration and Operation Notes +=================================================== + +1. configure --without-gnu-malloc on: + + alpha running OSF/1, Linux, or NetBSD (malloc needs 8-byte alignment; + bash malloc has 8-byte alignment now, but I have no alphas to test on) + + next running NeXT/OS + + all machines running SunOS YP code: SunOS4, SunOS5, HP/UX, if you + have problems with username completion or tilde expansion for + usernames found via YP/NIS + + linux (optional, but don't do it if you're using Doug Lea's malloc) + + QNX 4.2 + other OSF/1 machines (KSR/1, HP, IBM AIX/ESA) + AIX + sparc SVR4, SVR4.2 (ICL reference port) + DG/UX + Cray + + NetBSD/sparc (malloc needs 8-byte alignment; bash malloc has 8-byte + alignment now, but I have no NetBSD machines to test on) + + BSD/OS 2.1, 3.x if you want to use loadable builtins + + Motorola m68k machines running System V.3.

Editing the Makefile after + configure runs and removing the `-lnsl' from the assignment to `LIBS' + fixes the problem. + +5. There is a problem with the `makewhatis' script in older (pre-7.0) + versions of Red Hat Linux. Running `makewhatis' with bash-2.0 or + later versions results in error messages like this: + + /usr/sbin/makewhatis: cd: manpath: No such file or directory + /usr/sbin/makewhatis: manpath/whatis: No such file or directory + chmod: manpath/whatis: No such file or directory + /usr/sbin/makewhatis: cd: catpath: No such file or directory + /usr/sbin/makewhatis: catpath/whatis: No such file or directory + chmod: catpath/whatis: No such file or directory + + The problem is with `makewhatis'. Red Hat (and possibly other + Linux distributors) uses a construct like this in the code: + + eval path=$"$pages"path + + to do indirect variable expansion. This `happened to work' in + bash-1.14 and previous versions, but that was more an accident + of implementation than anything else -- it was never supported + and certainly is not portable. + + Bash-2.0 has a new feature that gives a new meaning to $"...". + This is explained more completely in item 1 in the COMPAT file. + + The three lines in the `makewhatis' script that need to be changed + look like this: + + eval $topath=$"$topath":$name + [...] + eval path=$"$pages"path + [...] + eval path=$"$pages"path + + The portable way to write this code is + + eval $topath="\$$topath":$name + eval path="\$$pages"path + eval path="\$$pages"path + + You could also experiment with another new bash feature: ${!var}. + This does indirect variable expansion, making the use of eval + unnecessary. + +6. There is a problem with syslogd on many Linux distributions (Red Hat + and Slackware are two that I have received reports about). syslogd + sends a SIGINT to its parent process, which is waiting for the daemon + to finish its initialization. The parent process then dies due to + the SIGINT, and bash reports it, causing unexpected console output + while the system is booting that looks something like + + starting daemons: syslogd/etc/rc.d/rc.M: line 29: 38 Interrupt ${NET}/syslogd + + Bash-2.0 reports events such as processes dying in scripts due to + signals when the standard output is a tty. Bash-1.14.x and previous + versions did not report such events. + + This should probably be reported as a bug to whatever Linux distributor + people see the problem on. In my opinion, syslogd should be changed to + use some other method of communication, or the wrapper function (which + appeared to be `daemon' when I looked at it some time ago) or script + (which appeared to be `syslog') should catch SIGINT, since it's an + expected event, and exit cleanly. + +7. Several people have reported that `dip' (a program for SLIP/PPP + on Linux) does not work with bash-2.0 installed as /bin/sh. + + I don't run any Linux boxes myself, and do not have the dip + code handy to look at, but the `problem' with bash-2.0, as + it has been related to me, is that bash requires the `-p' + option to be supplied at invocation if it is to run setuid + or setgid. + + This means, among other things, that setuid or setgid programs + which call system(3) (a horrendously bad practice in any case) + relinquish their setuid/setgid status in the child that's forked + to execute /bin/sh. + + The following is an *unofficial* patch to bash-2.0 that causes it + to not require `-p' to run setuid or setgid if invoked as `sh'. + It has been reported to work on Linux.

The easiest solution is to swap /bin/sh + with /usr/bin/ash. Then use chmem(1) to increase the memory allocated + to /bin/sh. The following settings are known to work: + + text data bss stack memory + 63552 9440 3304 65536 141832 /bin/sh + + If you have problems with make or yacc it may be worthwhile first to + install the GNU versions of these utilities before attempting to build + bash. (As of this writing, all of these utilities are available for the + i386 as pre-built binaries via anonymous ftp at math.syr.edu in the + pub/mcconnell/minix directory. Note that the GNU version of yacc is called + bison.) + + Unless you want to see lots of warnings about old-style declarations, + do LOCAL_CFLAGS=-wo; export LOCAL_CFLAGS before running configure. + (These warnings are harmless, but annoying.) + + configure will insist that you supply a host type. For example, do + ./configure --host=i386-pc-minix. + + Minix does not support the system calls required for a proper + implementation of ulimit(). The `ulimit' builtin will not be available. + + Configure will fail to notice that many things like uid_t are indeed + typedef'd in , because it uses egrep for this purpose + and minix has no egrep. You could try making a link /usr/bin/egrep --> + /usr/bin/grep. Better is to install the GNU version of grep in + /usr/local/bin and make the link /usr/local/bin/egrep -->/usr/local/bin/grep. + (These must be hard links, of course, since Minix does not support + symbolic links.) + + You will see many warnings of the form: + warning: unknown s_type: 98 + I have no idea what this means, but it doesn't seem to matter. + +10. If you do not have /usr/ccs/bin in your PATH when building on SunOS 5.x + (Solaris 2), the configure script will be unable to find `ar' and + `ranlib' (of course, ranlib is unnecessary). Make sure your $PATH + includes /usr/ccs/bin on SunOS 5.x. This generally manifests itself + with libraries not being built and make reporting errors like + `cr: not found' when library construction is attempted. + +11. Building a statically-linked bash on Solaris 2.5.x, 2.6, 7, or 8 is + complicated. + + It's not possible to build a completely statically-linked binary, since + part of the C library depends on dynamic linking. The following recipe + assumes that you're using gcc and the Solaris ld (/usr/ccs/bin/ld) on + Solaris 2.5.x or 2.6: + + configure --enable-static-link + make STATIC_LD= LOCAL_LIBS='-Wl,-B,dynamic -ldl -Wl,-B,static' + + This should result in a bash binary that depends only on libdl.so: + + thor(2)$ ldd bash + libdl.so.1 => /usr/lib/libdl.so.1 + + If you're using the Sun C Compiler (Sun WorkShop C Compiler version + 4.2 was what I used), you should be able to get away with using + + configure --enable-static-link + make STATIC_LD= LOCAL_LIBS='-B dynamic -ldl -B static' + + If you want to completely remove any dependence on /usr, perhaps + to put a copy of bash in /sbin and have it available when /usr is + not mounted, force the build process to use the shared dl.so library + in /etc/lib. + + For gcc, this would be something like + + configure --enable-static-link + make STATIC_LD= LOCAL_LIBS='-Wl,-B,dynamic -Wl,-R/etc/lib -ldl -Wl,-B,static' + + For Sun's WS4.2 cc + + configure --enable-static-link + make STATIC_LD= LOCAL_LIBS='-B dynamic -R/etc/lib -ldl -B static' + + seems to work, at least on Solaris 2.5.1: + + thor(2)$ ldd bash + libdl.so.1 => /etc/lib/libdl.so.1 + + On Solaris 7 (Solaris 8, using the version of gcc on the free software + CD-ROM), the following recipe appears to work for gcc: + + configure --enable-static-link + make STATIC_LD='-Wl,-Bstatic' LOCAL_LIBS='-Wl,-Bdynamic -Wl,-R/etc/lib -ldl -Wl,-Bstatic' + + thor.ins.cwru.edu(2)$ ldd bash + libdl.so.1 => /etc/lib/libdl.so.1 + + Make the analogous changes if you are running Sun's C Compiler. + + I have received word that adding -L/etc/lib (or the equivalent + -Wl,-L/etc/lib) might also be necessary, in addition to the -R/etc/lib. + +12. Configuring bash to build it in a cross environment. Currently only + two native versions can be compiled this way, cygwin32 and x86 BeOS. + For BeOS, you would configure it like this: + + export RANLIB=i586-beos-ranlib + export AR=i586-beos-ar + export CC=i586-beos-gcc + configure i586-beos + + Similarly for cygwin32. + +13. Bash-2.05 has reverted to the bash-2.03 behavior of honoring the current + locale setting when processing ranges within pattern matching bracket + expressions ([A-Z]). This is what POSIX.2 and SUSv2 specify. + + The behavior of the matcher in bash-2.05 depends on the current LC_COLLATE + setting. Setting this variable to `C' or `POSIX' will result in the + traditional behavior ([A-Z] matches all uppercase ASCII characters). + Many other locales, including the en_US locale (the default on many US + versions of Linux) collate the upper and lower case letters like this: + + AaBb...Zz + + which means that [A-Z] matches every letter except `z'. + + The portable way to specify upper case letters is [:upper:] instead of + A-Z; lower case may be specified as [:lower:] instead of a-z. + + Look at the manual pages for setlocale(3), strcoll(3), and, if it is + present, locale(1). If you have locale(1), you can use it to find + your current locale information even if you do not have any of the + LC_ variables set. + + My advice is to put + + export LC_COLLATE=C + + into /etc/profile and inspect any shell scripts run from cron for + constructs like [A-Z]. This will prevent things like + + rm [A-Z]* + + from removing every file in the current directory except those beginning + with `z' and still allow individual users to change the collation order. + Users may put the above command into their own profiles as well, of course. + +14. Building on Interix (nee OpenNT), which Microsoft bought from Softway + Systems and has seemingly abandoned (thanks to Kevin Moore for this item). + + 1. cp cross-build/opennt.cache config.cache + + 2. If desired, edit pathnames.h to set the values of SYS_PROFILE and + DEFAULT_HOSTS_FILE appropriately. + + 3. export CONFIG_SHELL=$INTERIX_ROOT/bin/sh + + 4. ./configure --prefix=$INTERIX_ROOT/usr/local (or wherever you + want it). + + 5. make; make install; enjoy + +15. Configure with `CC=xlc' if you don't have gcc on AIX 4.2 and later + versions. `xlc' running in `cc' mode has trouble compiling error.c. + +16. Configure --disable-multibyte on NetBSD versions (1.4 through at least + 1.6.1) that include wctype.h but do not define wctype_t. + +17. Do NOT use bison-1.75. It builds a non-working parser. The most + obvious effect is that constructs like "for i; do echo $i; done" don't + loop over the positional parameters. diff --git a/bash-20060316/POSIX b/bash-20060316/POSIX new file mode 100644 index 000000000..f8c983ea2 --- /dev/null +++ b/bash-20060316/POSIX @@ -0,0 +1,179 @@ +6.11 Bash POSIX Mode +==================== + +Starting Bash with the `--posix' command-line option or executing `set +-o posix' while Bash is running will cause Bash to conform more closely +to the POSIX 1003.2 standard by changing the behavior to match that +specified by POSIX in areas where the Bash default differs. + +When invoked as `sh', Bash enters POSIX mode after reading the startup +files. + +The following list is what's changed when `POSIX mode' is in effect: + + 1. When a command in the hash table no longer exists, Bash will + re-search `$PATH' to find the new location. This is also + available with `shopt -s checkhash'. + + 2. The message printed by the job control code and builtins when a job + exits with a non-zero status is `Done(status)'. + + 3. The message printed by the job control code and builtins when a job + is stopped is `Stopped(SIGNAME)', where SIGNAME is, for example, + `SIGTSTP'. + + 4. The `bg' builtin uses the required format to describe each job + placed in the background, which does not include an indication of + whether the job is the current or previous job. + + 5. Reserved words appearing in a context where reserved words are + recognized do not undergo alias expansion. + + 6. The POSIX 1003.2 `PS1' and `PS2' expansions of `!' to the history + number and `!!' to `!' are enabled, and parameter expansion is + performed on the values of `PS1' and `PS2' regardless of the + setting of the `promptvars' option. + + 7. The POSIX 1003.2 startup files are executed (`$ENV') rather than + the normal Bash files. + + 8. Tilde expansion is only performed on assignments preceding a + command name, rather than on all assignment statements on the line. + + 9. The default history file is `~/.sh_history' (this is the default + value of `$HISTFILE'). + + 10. The output of `kill -l' prints all the signal names on a single + line, separated by spaces, without the `SIG' prefix. + + 11. The `kill' builtin does not accept signal names with a `SIG' + prefix. + + 12. Non-interactive shells exit if FILENAME in `.' FILENAME is not + found. + + 13. Non-interactive shells exit if a syntax error in an arithmetic + expansion results in an invalid expression. + + 14. Redirection operators do not perform filename expansion on the word + in the redirection unless the shell is interactive. + + 15. Redirection operators do not perform word splitting on the word in + the redirection. + + 16. Function names must be valid shell `name's. That is, they may not + contain characters other than letters, digits, and underscores, and + may not start with a digit. Declaring a function with an invalid + name causes a fatal syntax error in non-interactive shells. + + 17. POSIX 1003.2 special builtins are found before shell functions + during command lookup. + + 18. If a POSIX 1003.2 special builtin returns an error status, a + non-interactive shell exits. The fatal errors are those listed in + the POSIX.2 standard, and include things like passing incorrect + options, redirection errors, variable assignment errors for + assignments preceding the command name, and so on. + + 19. If `CDPATH' is set, the `cd' builtin will not implicitly append + the current directory to it. This means that `cd' will fail if no + valid directory name can be constructed from any of the entries in + `$CDPATH', even if the a directory with the same name as the name + given as an argument to `cd' exists in the current directory. + + 20. A non-interactive shell exits with an error status if a variable + assignment error occurs when no command name follows the assignment + statements. A variable assignment error occurs, for example, when + trying to assign a value to a readonly variable. + + 21. A non-interactive shell exits with an error status if the iteration + variable in a `for' statement or the selection variable in a + `select' statement is a readonly variable. + + 22. Process substitution is not available. + + 23. Assignment statements preceding POSIX 1003.2 special builtins + persist in the shell environment after the builtin completes. + + 24. Assignment statements preceding shell function calls persist in the + shell environment after the function returns, as if a POSIX + special builtin command had been executed. + + 25. The `export' and `readonly' builtin commands display their output + in the format required by POSIX 1003.2. + + 26. The `trap' builtin displays signal names without the leading `SIG'. + + 27. The `trap' builtin doesn't check the first argument for a possible + signal specification and revert the signal handling to the original + disposition if it is, unless that argument consists solely of + digits and is a valid signal number. If users want to reset the + handler for a given signal to the original disposition, they + should use `-' as the first argument. + + 28. The `.' and `source' builtins do not search the current directory + for the filename argument if it is not found by searching `PATH'. + + 29. Subshells spawned to execute command substitutions inherit the + value of the `-e' option from the parent shell. When not in POSIX + mode, Bash clears the `-e' option in such subshells. + + 30. Alias expansion is always enabled, even in non-interactive shells. + + 31. When the `alias' builtin displays alias definitions, it does not + display them with a leading `alias ' unless the `-p' option is + supplied. + + 32. When the `set' builtin is invoked without options, it does not + display shell function names and definitions. + + 33. When the `set' builtin is invoked without options, it displays + variable values without quotes, unless they contain shell + metacharacters, even if the result contains nonprinting characters. + + 34. When the `cd' builtin is invoked in LOGICAL mode, and the pathname + constructed from `$PWD' and the directory name supplied as an + argument does not refer to an existing directory, `cd' will fail + instead of falling back to PHYSICAL mode. + + 35. When the `pwd' builtin is supplied the `-P' option, it resets + `$PWD' to a pathname containing no symlinks. + + 36. The `pwd' builtin verifies that the value it prints is the same as + the current directory, even if it is not asked to check the file + system with the `-P' option. + + 37. When listing the history, the `fc' builtin does not include an + indication of whether or not a history entry has been modified. + + 38. The default editor used by `fc' is `ed'. + + 39. The `type' and `command' builtins will not report a non-executable + file as having been found, though the shell will attempt to + execute such a file if it is the only so-named file found in + `$PATH'. + + 40. The `vi' editing mode will invoke the `vi' editor directly when + the `v' command is run, instead of checking `$FCEDIT' and + `$EDITOR'. + + 41. When the `xpg_echo' option is enabled, Bash does not attempt to + interpret any arguments to `echo' as options. Each argument is + displayed, after escape characters are converted. + + +There is other POSIX 1003.2 behavior that Bash does not implement by +default even when in POSIX mode. Specifically: + + 1. The `fc' builtin checks `$EDITOR' as a program to edit history + entries if `FCEDIT' is unset, rather than defaulting directly to + `ed'. `fc' uses `ed' if `EDITOR' is unset. + + 2. As noted above, Bash requires the `xpg_echo' option to be enabled + for the `echo' builtin to be fully conformant. + + +Bash can be configured to be POSIX-conformant by default, by specifying +the `--enable-strict-posix-default' to `configure' when building (*note +Optional Features::). + diff --git a/bash-20060316/RBASH b/bash-20060316/RBASH new file mode 100644 index 000000000..0e5c10b3e --- /dev/null +++ b/bash-20060316/RBASH @@ -0,0 +1,49 @@ +6.10 The Restricted Shell +========================= + +If Bash is started with the name `rbash', or the `--restricted' or `-r' +option is supplied at invocation, the shell becomes restricted.

Bash is the GNU Project's Bourne +Again SHell, a complete implementation of the POSIX.2 shell spec, +but also with interactive command line editing, job control on +architectures that support it, csh-like features such as history +substitution and brace expansion, and a slew of other features. +For more information on the features of Bash that are new to this +type of shell, see the file `doc/bashref.texi'. There is also a +large Unix-style man page. The man page is the definitive description +of the shell's features. + +See the file POSIX for a discussion of how the Bash defaults differ +from the POSIX.2 spec and a description of the Bash `posix mode'. + +There are some user-visible incompatibilities between this version +of Bash and a previous widely-distributed version, bash-1.14. +For details, see the file COMPAT. The NEWS file tersely lists +features that are new in this release. + +Bash is free software, distributed under the terms of the [GNU] +General Public License, version 2. For more information, see the +file COPYING. + +A number of frequently-asked questions are answered in the file +`doc/FAQ'. + +To compile Bash, try typing `./configure', then `make'. Bash +auto-configures the build process, so no further intervention +should be necessary. Bash builds with `gcc' by default if it is +available. If you want to use `cc' instead, type + + CC=cc ./configure + +if you are using a Bourne-style shell. If you are not, the following +may work: + + env CC=cc ./configure + +Read the file INSTALL in this directory for more information about how +to customize and control the build process. The file NOTES contains +platform-specific installation and configuration information. + +If you are a csh user and wish to convert your csh aliases to Bash +aliases, you may wish to use the script `examples/misc/alias-conv.sh' +as a starting point. The script `examples/misc/cshtobash' is a +more ambitious script that attempts to do a more complete job. + +Reporting Bugs +============== + +Bug reports for bash should be sent to: + + bug-bash@gnu.org + +using the `bashbug' program that is built and installed at the same +time as bash. + +The discussion list `bug-bash@gnu.org' often contains information +about new ports of Bash, or discussions of new features or behavior +changes that people would like.

The +dnl default (if it is not specified or empty) is 'no-libtool'. +dnl INTLSYMBOL should be 'external' for packages with no intl directory, +dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. +dnl If INTLSYMBOL is 'use-libtool', then a libtool library +dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, +dnl depending on --{enable,disable}-{shared,static} and on the presence of +dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library +dnl $(top_builddir)/intl/libintl.a will be created. +dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext +dnl implementations (in libc or libintl) without the ngettext() function +dnl will be ignored. If NEEDSYMBOL is specified and is +dnl 'need-formatstring-macros', then GNU gettext implementations that don't +dnl support the ISO C 99 formatstring macros will be ignored. +dnl INTLDIR is used to find the intl libraries. If empty, +dnl the value `$(top_builddir)/intl/' is used. +dnl +dnl The result of the configuration is one of three cases: +dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled +dnl and used. +dnl Catalog format: GNU --> install in $(datadir) +dnl Catalog extension: .mo after installation, .gmo in source tree +dnl 2) GNU gettext has been found in the system's C library. +dnl Catalog format: GNU --> install in $(datadir) +dnl Catalog extension: .mo after installation, .gmo in source tree +dnl 3) No internationalization, always use English msgid. +dnl Catalog format: none +dnl Catalog extension: none +dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. +dnl The use of .gmo is historical (it was needed to avoid overwriting the +dnl GNU format catalogs when building on a platform with an X/Open gettext), +dnl but we keep it in order not to force irrelevant filename changes on the +dnl maintainers. +dnl +AC_DEFUN([AM_GNU_GETTEXT], +[ + dnl Argument checking. + ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , + [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT +])])])])]) + ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , + [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT +])])])]) + define(gt_included_intl, ifelse([$1], [external], [no], [yes])) + define(gt_libtool_suffix_prefix, ifelse([$1], [use-libtool], [l], [])) + + AC_REQUIRE([AM_PO_SUBDIRS])dnl + ifelse(gt_included_intl, yes, [ + AC_REQUIRE([AM_INTL_SUBDIR])dnl + ]) + + dnl Prerequisites of AC_LIB_LINKFLAGS_BODY. + AC_REQUIRE([AC_LIB_PREPARE_PREFIX]) + AC_REQUIRE([AC_LIB_RPATH]) + + dnl Sometimes libintl requires libiconv, so first search for libiconv. + dnl Ideally we would do this search only after the + dnl if test "$USE_NLS" = "yes"; then + dnl if test "$gt_cv_func_gnugettext_libc" != "yes"; then + dnl tests.

It is an implementation of +the Posix 1003.2 shell standard, and resembles the Korn and System V +shells. + +Bash contains a number of enhancements over those shells, both +for interactive use and shell programming. Features geared +toward interactive use include command line editing, command +history, job control, aliases, and prompt expansion. Programming +features include additional variable expansions, shell +arithmetic, and a number of variables and options to control +shell behavior. + +Bash was originally written by Brian Fox of the Free Software +Foundation. The current developer and maintainer is Chet Ramey +of Case Western Reserve University. + +A2) What's the latest version? + +The latest version is 3.1, first made available on 09 December, 2005. + +A3) Where can I get it? + +Bash is the GNU project's shell, and so is available from the +master GNU archive site, ftp.gnu.org, and its mirrors. The +latest version is also available for FTP from ftp.cwru.edu. +The following URLs tell how to get version 3.1: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-3.1.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-3.1.tar.gz + +Formatted versions of the documentation are available with the URLs: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-doc-3.1.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-doc-3.1.tar.gz + +Any patches for the current version are available with the URL: + +ftp://ftp.cwru.edu/pub/bash/bash-3.1-patches/ + +A4) On what machines will bash run? + +Bash has been ported to nearly every version of Unix. All you +should have to do to build it on a machine for which a port +exists is to type `configure' and then `make'. The build process +will attempt to discover the version of Unix you have and tailor +itself accordingly, using a script created by GNU autoconf. + +More information appears in the file `INSTALL' in the distribution. + +The Bash web page (http://cnswww.cns.cwru.edu/~chet/bash/bashtop.html) +explains how to obtain binary versions of bash for most of the major +commercial Unix systems. + +A5) Will bash run on operating systems other than Unix? + +Configuration specifics for Unix-like systems such as QNX and +LynxOS are included in the distribution. Bash-2.05 and later +versions should compile and run on Minix 2.0 (patches were +contributed), but I don't believe anyone has built bash-2.x on +earlier Minix versions yet. + +Bash has been ported to versions of Windows implementing the Win32 +programming interface. This includes Windows 95 and Windows NT. +The port was done by Cygnus Solutions (now part of Red Hat) as part +of their CYGWIN project. For more information about the project, see +http://www.cygwin.com/. + +Cygnus originally ported bash-1.14.7, and that port was part of their +early GNU-Win32 (the original name) releases. Cygnus has also done +ports of bash-2.05b and bash-3.0 to the CYGWIN environment, and both +are available as part of their current release. Bash-3.1 is currently +being tested and should be available soon. + +Bash-2.05b and later versions should require no local Cygnus changes to +build and run under CYGWIN. + +DJ Delorie has a port of bash-2.x which runs under MS-DOS, as part +of the DJGPP project. For more information on the project, see + +http://www.delorie.com/djgpp/ + +I have been told that the original DJGPP port was done by Daisuke Aoyama. + +Mark Elbrecht has sent me notice that bash-2.04 +is available for DJGPP V2. The files are available as: + +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204b.zip binary +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204d.zip documentation +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204s.zip source + +Mark began to work with bash-2.05, but I don't know the current status. + +Bash-3.0 compiles and runs with no modifications under Microsoft's Services +for Unix (SFU), once known as Interix. I do not anticipate any problems +with building bash-3.1. + +A6) How can I build bash with gcc? + +Bash configures to use gcc by default if it is available. Read the +file INSTALL in the distribution for more information. + +A7) How can I make bash my login shell? + +Some machines let you use `chsh' to change your login shell. Other +systems use `passwd -s' or `passwd -e'. If one of these works for +you, that's all you need. Note that many systems require the full +pathname to a shell to appear in /etc/shells before you can make it +your login shell. For this, you may need the assistance of your +friendly local system administrator. + +If you cannot do this, you can still use bash as your login shell, but +you need to perform some tricks. The basic idea is to add a command +to your login shell's startup file to replace your login shell with +bash. + +For example, if your login shell is csh or tcsh, and you have installed +bash in /usr/gnu/bin/bash, add the following line to ~/.login: + + if ( -f /usr/gnu/bin/bash ) exec /usr/gnu/bin/bash --login + +(the `--login' tells bash that it is a login shell). + +It's not a good idea to put this command into ~/.cshrc, because every +csh you run without the `-f' option, even ones started to run csh scripts, +reads that file. If you must put the command in ~/.cshrc, use something +like + + if ( $?prompt ) exec /usr/gnu/bin/bash --login + +to ensure that bash is exec'd only when the csh is interactive. + +If your login shell is sh or ksh, you have to do two things. + +First, create an empty file in your home directory named `.bash_profile'. +The existence of this file will prevent the exec'd bash from trying to +read ~/.profile, and re-execing itself over and over again. ~/.bash_profile +is the first file bash tries to read initialization commands from when +it is invoked as a login shell. + +Next, add a line similar to the above to ~/.profile: + + [ -f /usr/gnu/bin/bash ] && [ -x /usr/gnu/bin/bash ] && \ + exec /usr/gnu/bin/bash --login + +This will cause login shells to replace themselves with bash running as +a login shell. Once you have this working, you can copy your initialization +code from ~/.profile to ~/.bash_profile. + +I have received word that the recipe supplied above is insufficient for +machines running CDE. CDE has a maze of twisty little startup files, all +slightly different. + +If you cannot change your login shell in the password file to bash, you +will have to (apparently) live with CDE using the shell in the password +file to run its startup scripts. If you have changed your shell to bash, +there is code in the CDE startup files (on Solaris, at least) that attempts +to do the right thing. It is, however, often broken, and may require that +you use the $BASH_ENV trick described below. + +`dtterm' claims to use $SHELL as the default program to start, so if you +can change $SHELL in the CDE startup files, you should be able to use bash +in your terminal windows. + +Setting DTSOURCEPROFILE in ~/.dtprofile will cause the `Xsession' program +to read your login shell's startup files. You may be able to use bash for +the rest of the CDE programs by setting SHELL to bash in ~/.dtprofile as +well, but I have not tried this. + +You can use the above `exec' recipe to start bash when not logging in with +CDE by testing the value of the DT variable: + + if [ -n "$DT" ]; then + [ -f /usr/gnu/bin/bash ] && exec /usr/gnu/bin/bash --login + fi + +If CDE starts its shells non-interactively during login, the login shell +startup files (~/.profile, ~/.bash_profile) will not be sourced at login. +To get around this problem, append a line similar to the following to your +~/.dtprofile: + + BASH_ENV=${HOME}/.bash_profile ; export BASH_ENV + +and add the following line to the beginning of ~/.bash_profile: + + unset BASH_ENV + +A8) I just changed my login shell to bash, and now I can't FTP into my + machine. Why not? + +You must add the full pathname to bash to the file /etc/shells. As +noted in the answer to the previous question, many systems require +this before you can make bash your login shell. + +Most versions of ftpd use this file to prohibit `special' users +such as `uucp' and `news' from using FTP. + +A9) What's the `POSIX Shell and Utilities standard'? + +POSIX is a name originally coined by Richard Stallman for a +family of open system standards based on UNIX. There are a +number of aspects of UNIX under consideration for +standardization, from the basic system services at the system +call and C library level to applications and tools to system +administration and management. Each area of standardization is +assigned to a working group in the 1003 series. + +The POSIX Shell and Utilities standard was originally developed by +IEEE Working Group 1003.2 (POSIX.2). Today it has been merged with +the original 1003.1 Working Group and is maintained by the Austin +Group (a joint working group of the IEEE, The Open Group and +ISO/IEC SC22/WG15). Today the Shell and Utilities are a volume +within the set of documents that make up IEEE Std 1003.1-2001, and +thus now the former POSIX.2 (from 1992) is now part of the current +POSIX.1 standard (POSIX 1003.1-2001). + +The Shell and Utilities volume concentrates on the command +interpreter interface and utility programs commonly executed from +the command line or by other programs. The standard is freely +available on the web at http://www.UNIX-systems.org/version3/ . +Work continues at the Austin Group on maintenance issues; see +http://www.opengroup.org/austin/ to join the discussions. + +Bash is concerned with the aspects of the shell's behavior defined +by the POSIX Shell and Utilities volume. The shell command +language has of course been standardized, including the basic flow +control and program execution constructs, I/O redirection and +pipelining, argument handling, variable expansion, and quoting. + +The `special' builtins, which must be implemented as part of the +shell to provide the desired functionality, are specified as +being part of the shell; examples of these are `eval' and +`export'. Other utilities appear in the sections of POSIX not +devoted to the shell which are commonly (and in some cases must +be) implemented as builtin commands, such as `read' and `test'. +POSIX also specifies aspects of the shell's interactive +behavior as part of the UPE, including job control and command +line editing. Only vi-style line editing commands have been +standardized; emacs editing commands were left out due to +objections. + +The latest version of the POSIX Shell and Utilities standard is +available (now updated to the 2004 Edition) as part of the Single +UNIX Specification Version 3 at + +http://www.UNIX-systems.org/version3/ + +A10) What is the bash `posix mode'? + +Although bash is an implementation of the POSIX shell +specification, there are areas where the bash default behavior +differs from that spec. The bash `posix mode' changes the bash +behavior in these areas so that it obeys the spec more closely. + +Posix mode is entered by starting bash with the --posix or +'-o posix' option or executing `set -o posix' after bash is running. + +The specific aspects of bash which change when posix mode is +active are listed in the file POSIX in the bash distribution. +They are also listed in a section in the Bash Reference Manual +(from which that file is generated). + +Section B: The latest version + +B1) What's new in version 3.1? + +Bash-3.1 is the first maintenance release of the third major release of +bash. It contains the following significant new features (see the manual +page for complete descriptions and the CHANGES and NEWS files in the +bash-3.1 distribution). + +o Bash-3.1 may now be configured and built in a mode that enforces strict + POSIX compliance. + +o The `+=' assignment operator, which appends to the value of a string or + array variable, has been implemented. + +o It is now possible to ignore case when matching in contexts other than + filename generation using the new `nocasematch' shell option. + +A short feature history dating from Bash-2.0: + +Bash-3.0 contained the following new features: + +o Features to support the bash debugger have been implemented, and there + is a new `extdebug' option to turn the non-default options on + +o HISTCONTROL is now a colon-separated list of options and has been + extended with a new `erasedups' option that will result in only one + copy of a command being kept in the history list + +o Brace expansion has been extended with a new {x..y} form, producing + sequences of digits or characters + +o Timestamps are now kept with history entries, with an option to save + and restore them from the history file; there is a new HISTTIMEFORMAT + variable describing how to display the timestamps when listing history + entries + +o The `[[' command can now perform extended regular expression (egrep-like) + matching, with matched subexpressions placed in the BASH_REMATCH array + variable + +o A new `pipefail' option causes a pipeline to return a failure status if + any command in it fails + +o The `jobs', `kill', and `wait' builtins now accept job control notation + in their arguments even if job control is not enabled + +o The `gettext' package and libintl have been integrated, and the shell + messages may be translated into other languages + +Bash-2.05b introduced the following new features: + +o support for multibyte characters has been added to both bash and readline + +o the DEBUG trap is now run *before* simple commands, ((...)) commands, + [[...]] conditional commands, and for ((...)) loops + +o the shell now performs arithmetic in the largest integer size the machine + supports (intmax_t) + +o there is a new \D{...} prompt expansion; passes the `...' to strftime(3) + and inserts the result into the expanded prompt + +o there is a new `here-string' redirection operator: <<< word + +o when displaying variables, function attributes and definitions are shown + separately, allowing them to be re-used as input (attempting to re-use + the old output would result in syntax errors). + +o `read' has a new `-u fd' option to read from a specified file descriptor + +o the bash debugger in examples/bashdb has been modified to work with the + new DEBUG trap semantics, the command set has been made more gdb-like, + and the changes to $LINENO make debugging functions work better + +o the expansion of $LINENO inside a shell function is only relative to the + function start if the shell is interactive -- if the shell is running a + script, $LINENO expands to the line number in the script. This is as + POSIX-2001 requires + +Bash-2.05a introduced the following new features: + +o The `printf' builtin has undergone major work + +o There is a new read-only `shopt' option: login_shell, which is set by + login shells and unset otherwise + +o New `\A' prompt string escape sequence; expanding to time in 24-hour + HH:MM format + +o New `-A group/-g' option to complete and compgen; goes group name + completion + +o New [+-]O invocation option to set and unset `shopt' options at startup + +o ksh-like `ERR' trap + +o `for' loops now allow empty word lists after the `in' reserved word + +o new `hard' and `soft' arguments for the `ulimit' builtin + +o Readline can be configured to place the user at the same point on the line + when retrieving commands from the history list + +o Readline can be configured to skip `hidden' files (filenames with a leading + `.' on Unix) when performing completion + +Bash-2.05 introduced the following new features: + +o This version has once again reverted to using locales and strcoll(3) when + processing pattern matching bracket expressions, as POSIX requires. +o Added a new `--init-file' invocation argument as a synonym for `--rcfile', + per the new GNU coding standards. +o The /dev/tcp and /dev/udp redirections now accept service names as well as + port numbers. +o `complete' and `compgen' now take a `-o value' option, which controls some + of the aspects of that compspec. Valid values are: + + default - perform bash default completion if programmable + completion produces no matches + dirnames - perform directory name completion if programmable + completion produces no matches + filenames - tell readline that the compspec produces filenames, + so it can do things like append slashes to + directory names and suppress trailing spaces +o A new loadable builtin, realpath, which canonicalizes and expands symlinks + in pathname arguments. +o When `set' is called without options, it prints function defintions in a + way that allows them to be reused as input. This affects `declare' and + `declare -p' as well. This only happens when the shell is not in POSIX + mode, since POSIX.2 forbids this behavior. + +Bash-2.04 introduced the following new features: + +o Programmable word completion with the new `complete' and `compgen' builtins; + examples are provided in examples/complete/complete-examples +o `history' has a new `-d' option to delete a history entry +o `bind' has a new `-x' option to bind key sequences to shell commands +o The prompt expansion code has new `\j' and `\l' escape sequences +o The `no_empty_cmd_completion' shell option, if enabled, inhibits + command completion when TAB is typed on an empty line +o `help' has a new `-s' option to print a usage synopsis +o New arithmetic operators: var++, var--, ++var, --var, expr1,expr2 (comma) +o New ksh93-style arithmetic for command: + for ((expr1 ; expr2; expr3 )); do list; done +o `read' has new options: `-t', `-n', `-d', `-s' +o The redirection code handles several filenames specially: /dev/fd/N, + /dev/stdin, /dev/stdout, /dev/stderr +o The redirection code now recognizes /dev/tcp/HOST/PORT and + /dev/udp/HOST/PORT and tries to open a TCP or UDP socket, respectively, + to the specified port on the specified host +o The ${!prefix*} expansion has been implemented +o A new FUNCNAME variable, which expands to the name of a currently-executing + function +o The GROUPS variable is no longer readonly +o A new shopt `xpg_echo' variable, to control the behavior of echo with + respect to backslash-escape sequences at runtime +o The NON_INTERACTIVE_LOGIN_SHELLS #define has returned + +The version of Readline released with Bash-2.04, Readline-4.1, had several +new features as well: + +o Parentheses matching is always compiled into readline, and controllable + with the new `blink-matching-paren' variable +o The history-search-forward and history-search-backward functions now leave + point at the end of the line when the search string is empty, like + reverse-search-history, and forward-search-history +o A new function for applications: rl_on_new_line_with_prompt() +o New variables for applications: rl_already_prompted, and rl_gnu_readline_p + + +Bash-2.03 had very few new features, in keeping with the convention +that odd-numbered releases provide mainly bug fixes.

+ +D1) Why does bash run a different version of `command' than + `which command' says it will? + +On many systems, `which' is actually a csh script that assumes +you're running csh. In tcsh, `which' and its cousin `where' +are builtins. On other Unix systems, `which' is a perl script +that uses the PATH environment variable. + +The csh script version reads the csh startup files from your +home directory and uses those to determine which `command' will +be invoked. Since bash doesn't use any of those startup files, +there's a good chance that your bash environment differs from +your csh environment. The bash `type' builtin does everything +`which' does, and will report correct results for the running +shell. If you're really wedded to the name `which', try adding +the following function definition to your .bashrc: + + which() + { + builtin type "$@" + } + +If you're moving from tcsh and would like to bring `where' along +as well, use this function: + + where() + { + builtin type -a "$@" + } + +D2) Why doesn't bash treat brace expansions exactly like csh? + +The only difference between bash and csh brace expansion is that +bash requires a brace expression to contain at least one unquoted +comma if it is to be expanded. Any brace-surrounded word not +containing an unquoted comma is left unchanged by the brace +expansion code. This affords the greatest degree of sh +compatibility. + +Bash, ksh, zsh, and pd-ksh all implement brace expansion this way. + +D3) Why doesn't bash have csh variable modifiers? + +Posix has specified a more powerful, albeit somewhat more cryptic, +mechanism cribbed from ksh, and bash implements it. + +${parameter%word} + Remove smallest suffix pattern.

(e.g., `csh') + +Pipe the output of `alias' through `aliasconv.sh', saving the +results into `bash_aliases': + + alias | bash aliasconv.sh >bash_aliases + +Edit `bash_aliases', carefully reading through any created +functions. You will need to change the names of some csh specific +variables to the bash equivalents. The script converts $cwd to +$PWD, $term to $TERM, $home to $HOME, $user to $USER, and $prompt +to $PS1. You may also have to add quotes to avoid unwanted +expansion. + +For example, the csh alias: + + alias cd 'cd \!*; echo $cwd' + +is converted to the bash function: + + cd () { command cd "$@"; echo $PWD ; } + +The only thing that needs to be done is to quote $PWD: + + cd () { command cd "$@"; echo "$PWD" ; } + +Merge the edited file into your ~/.bashrc. + +There is an additional, more ambitious, script in +examples/misc/cshtobash that attempts to convert your entire csh +environment to its bash equivalent. This script can be run as +simply `cshtobash' to convert your normal interactive +environment, or as `cshtobash ~/.login' to convert your login +environment. + +D5) How can I pipe standard output and standard error from one command to + another, like csh does with `|&'? + +Use + command 2>&1 | command2 + +The key is to remember that piping is performed before redirection, so +file descriptor 1 points to the pipe when it is duplicated onto file +descriptor 2. + +D6) Now that I've converted from ksh to bash, are there equivalents to + ksh features like autoloaded functions and the `whence' command? + +There are features in ksh-88 and ksh-93 that do not have direct bash +equivalents. Most, however, can be emulated with very little trouble. + +ksh-88 feature Bash equivalent +-------------- --------------- +compiled-in aliases set up aliases in .bashrc; some ksh aliases are + bash builtins (hash, history, type) +coprocesses named pipe pairs (one for read, one for write) +typeset +f declare -F +cd, print, whence function substitutes in examples/functions/kshenv +autoloaded functions examples/functions/autoload is the same as typeset -fu +read var?prompt read -p prompt var + +ksh-93 feature Bash equivalent +-------------- --------------- +sleep, getconf Bash has loadable versions in examples/loadables +${.sh.version} $BASH_VERSION +print -f printf +hist alias hist=fc +$HISTEDIT $FCEDIT + +Section E: How can I get bash to do certain things, and why does bash do + things the way it does? + +E1) Why is the bash builtin `test' slightly different from /bin/test? + +The specific example used here is [ ! x -o x ], which is false. + +Bash's builtin `test' implements the Posix.2 spec, which can be +summarized as follows (the wording is due to David Korn): + +Here is the set of rules for processing test arguments. + + 0 Args: False + 1 Arg: True iff argument is not null. + 2 Args: If first arg is !, True iff second argument is null. + If first argument is unary, then true if unary test is true + Otherwise error. + 3 Args: If second argument is a binary operator, do binary test of $1 $3 + If first argument is !, negate two argument test of $2 $3 + If first argument is `(' and third argument is `)', do the + one-argument test of the second argument. + Otherwise error. + 4 Args: If first argument is !, negate three argument test of $2 $3 $4. + Otherwise unspecified + 5 or more Args: unspecified. (Historical shells would use their + current algorithm). + +The operators -a and -o are considered binary operators for the purpose +of the 3 Arg case. + +As you can see, the test becomes (not (x or x)), which is false. + +E2) Why does bash sometimes say `Broken pipe'? + +If a sequence of commands appears in a pipeline, and one of the +reading commands finishes before the writer has finished, the +writer receives a SIGPIPE signal. Many other shells special-case +SIGPIPE as an exit status in the pipeline and do not report it. +For example, in: + + ps -aux | head + +`head' can finish before `ps' writes all of its output, and ps +will try to write on a pipe without a reader. In that case, bash +will print `Broken pipe' to stderr when ps is killed by a +SIGPIPE. + +As of bash-3.1, bash will not report SIGPIPE errors by default. You +can build a version of bash that will report such errors. + +E3) When I have terminal escape sequences in my prompt, why does bash + wrap lines at the wrong column? + +Readline, the line editing library that bash uses, does not know +that the terminal escape sequences do not take up space on the +screen. The redisplay code assumes, unless told otherwise, that +each character in the prompt is a `printable' character that +takes up one character position on the screen. + +You can use the bash prompt expansion facility (see the PROMPTING +section in the manual page) to tell readline that sequences of +characters in the prompt strings take up no screen space. + +Use the \[ escape to begin a sequence of non-printing characters, +and the \] escape to signal the end of such a sequence. + +E4) If I pipe the output of a command into `read variable', why doesn't + the output show up in $variable when the read command finishes? + +This has to do with the parent-child relationship between Unix +processes. It affects all commands run in pipelines, not just +simple calls to `read'. For example, piping a command's output +into a `while' loop that repeatedly calls `read' will result in +the same behavior. + +Each element of a pipeline, even a builtin or shell function, +runs in a separate process, a child of the shell running the +pipeline. A subprocess cannot affect its parent's environment. +When the `read' command sets the variable to the input, that +variable is set only in the subshell, not the parent shell. When +the subshell exits, the value of the variable is lost. + +Many pipelines that end with `read variable' can be converted +into command substitutions, which will capture the output of +a specified command. The output can then be assigned to a +variable: + + grep ^gnu /usr/lib/news/active | wc -l | read ngroup + +can be converted into + + ngroup=$(grep ^gnu /usr/lib/news/active | wc -l) + +This does not, unfortunately, work to split the text among +multiple variables, as read does when given multiple variable +arguments. If you need to do this, you can either use the +command substitution above to read the output into a variable +and chop up the variable using the bash pattern removal +expansion operators or use some variant of the following +approach. + +Say /usr/local/bin/ipaddr is the following shell script: + +#! /bin/sh +host `hostname` | awk '/address/ {print $NF}' + +Instead of using + + /usr/local/bin/ipaddr | read A B C D + +to break the local machine's IP address into separate octets, use + + OIFS="$IFS" + IFS=. + set -- $(/usr/local/bin/ipaddr) + IFS="$OIFS" + A="$1" B="$2" C="$3" D="$4" + +Beware, however, that this will change the shell's positional +parameters. If you need them, you should save them before doing +this. + +This is the general approach -- in most cases you will not need to +set $IFS to a different value. + +Some other user-supplied alternatives include: + +read A B C D << HERE + $(IFS=.; echo $(/usr/local/bin/ipaddr)) +HERE + +and, where process substitution is available, + +read A B C D < <(IFS=.; echo $(/usr/local/bin/ipaddr)) + +E5) I have a bunch of shell scripts that use backslash-escaped characters + in arguments to `echo'. Bash doesn't interpret these characters. Why + not, and how can I make it understand them? + +This is the behavior of echo on most Unix System V machines. + +The bash builtin `echo' is modeled after the 9th Edition +Research Unix version of `echo'. It does not interpret +backslash-escaped characters in its argument strings by default; +it requires the use of the -e option to enable the +interpretation. The System V echo provides no way to disable the +special characters; the bash echo has a -E option to disable +them. + +There is a configuration option that will make bash behave like +the System V echo and interpret things like `\t' by default. Run +configure with the --enable-xpg-echo-default option to turn this +on. Be aware that this will cause some of the tests run when you +type `make tests' to fail. + +There is a shell option, `xpg_echo', settable with `shopt', that will +change the behavior of echo at runtime. Enabling this option turns +on expansion of backslash-escape sequences. + +E6) Why doesn't a while or for loop get suspended when I type ^Z? + +This is a consequence of how job control works on Unix. The only +thing that can be suspended is the process group. This is a single +command or pipeline of commands that the shell forks and executes. + +When you run a while or for loop, the only thing that the shell forks +and executes are any commands in the while loop test and commands in +the loop bodies. These, therefore, are the only things that can be +suspended when you type ^Z. + +If you want to be able to stop the entire loop, you need to put it +within parentheses, which will force the loop into a subshell that +may be stopped (and subsequently restarted) as a single unit. + +E7) What about empty for loops in Makefiles? + +It's fairly common to see constructs like this in automatically-generated +Makefiles: + +SUBDIRS = @SUBDIRS@ + + ... + +subdirs-clean: + for d in ${SUBDIRS}; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +When SUBDIRS is empty, this results in a command like this being passed to +bash: + + for d in ; do + ( cd $d && ${MAKE} ${MFLAGS} clean ) + done + +In versions of bash before bash-2.05a, this was a syntax error. If the +reserved word `in' was present, a word must follow it before the semicolon +or newline. The language in the manual page referring to the list of words +being empty referred to the list after it is expanded. These versions of +bash required that there be at least one word following the `in' when the +construct was parsed. + +The idiomatic Makefile solution is something like: + +SUBDIRS = @SUBDIRS@ + +subdirs-clean: + subdirs=$SUBDIRS ; for d in $$subdirs; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +The latest updated POSIX standard has changed this: the word list +is no longer required. Bash versions 2.05a and later accept the +new syntax. + +E8) Why does the arithmetic evaluation code complain about `08'? + +The bash arithmetic evaluation code (used for `let', $(()), (()), and in +other places), interprets a leading `0' in numeric constants as denoting +an octal number, and a leading `0x' as denoting hexadecimal. This is +in accordance with the POSIX.2 spec, section 2.9.2.1, which states that +arithmetic constants should be handled as signed long integers as defined +by the ANSI/ISO C standard. + +The POSIX.2 interpretation committee has confirmed this: + +http://www.pasc.org/interps/unofficial/db/p1003.2/pasc-1003.2-173.html + +E9) Why does the pattern matching expression [A-Z]* match files beginning + with every letter except `z'? + +Bash-2.03, Bash-2.05 and later versions honor the current locale setting +when processing ranges within pattern matching bracket expressions ([A-Z]). +This is what POSIX.2 and SUSv3/XPG6 specify. + +The behavior of the matcher in bash-2.05 and later versions depends on the +current LC_COLLATE setting. Setting this variable to `C' or `POSIX' will +result in the traditional behavior ([A-Z] matches all uppercase ASCII +characters). Many other locales, including the en_US locale (the default +on many US versions of Linux) collate the upper and lower case letters like +this: + + AaBb...Zz + +which means that [A-Z] matches every letter except `z'. Others collate like + + aAbBcC...zZ + +which means that [A-Z] matches every letter except `a'. + +The portable way to specify upper case letters is [:upper:] instead of +A-Z; lower case may be specified as [:lower:] instead of a-z. + +Look at the manual pages for setlocale(3), strcoll(3), and, if it is +present, locale(1). If you have locale(1), you can use it to find +your current locale information even if you do not have any of the +LC_ variables set. + +My advice is to put + + export LC_COLLATE=C + +into /etc/profile and inspect any shell scripts run from cron for +constructs like [A-Z]. This will prevent things like + + rm [A-Z]* + +from removing every file in the current directory except those beginning +with `z' and still allow individual users to change the collation order. +Users may put the above command into their own profiles as well, of course. + +E10) Why does `cd //' leave $PWD as `//'? + +POSIX.2, in its description of `cd', says that *three* or more leading +slashes may be replaced with a single slash when canonicalizing the +current working directory. + +This is, I presume, for historical compatibility. Certain versions of +Unix, and early network file systems, used paths of the form +//hostname/path to access `path' on server `hostname'. + +E11) If I resize my xterm while another program is running, why doesn't bash + notice the change? + +This is another issue that deals with job control. + +The kernel maintains a notion of a current terminal process group. Members +of this process group (processes whose process group ID is equal to the +current terminal process group ID) receive terminal-generated signals like +SIGWINCH. (For more details, see the JOB CONTROL section of the bash +man page.) + +If a terminal is resized, the kernel sends SIGWINCH to each member of +the terminal's current process group (the `foreground' process group). + +When bash is running with job control enabled, each pipeline (which may be +a single command) is run in its own process group, different from bash's +process group. This foreground process group receives the SIGWINCH; bash +does not. Bash has no way of knowing that the terminal has been resized. + +There is a `checkwinsize' option, settable with the `shopt' builtin, that +will cause bash to check the window size and adjust its idea of the +terminal's dimensions each time a process stops or exits and returns control +of the terminal to bash. Enable it with `shopt -s checkwinsize'. + +E12) Why don't negative offsets in substring expansion work like I expect? + +When substring expansion of the form ${param:offset[:length} is used, +an `offset' that evaluates to a number less than zero counts back from +the end of the expanded value of $param. + +When a negative `offset' begins with a minus sign, however, unexpected things +can happen. Consider + + a=12345678 + echo ${a:-4} + +intending to print the last four characters of $a. The problem is that +${param:-word} already has a well-defined meaning: expand to word if the +expanded value of param is unset or null, and $param otherwise. + +To use negative offsets that begin with a minus sign, separate the +minus sign and the colon with a space. + +Section F: Things to watch out for on certain Unix versions + +F1) Why can't I use command line editing in my `cmdtool'? + +The problem is `cmdtool' and bash fighting over the input. When +scrolling is enabled in a cmdtool window, cmdtool puts the tty in +`raw mode' to permit command-line editing using the mouse for +applications that cannot do it themselves. As a result, bash and +cmdtool each try to read keyboard input immediately, with neither +getting enough of it to be useful. + +This mode also causes cmdtool to not implement many of the +terminal functions and control sequences appearing in the +`sun-cmd' termcap entry. For a more complete explanation, see +that file examples/suncmd.termcap in the bash distribution. + +`xterm' is a better choice, and gets along with bash much more +smoothly. + +If you must use cmdtool, you can use the termcap description in +examples/suncmd.termcap. Set the TERMCAP variable to the terminal +description contained in that file, i.e. + +TERMCAP='Mu|sun-cmd:am:bs:km:pt:li#34:co#80:cl=^L:ce=\E[K:cd=\E[J:rs=\E[s:' + +Then export TERMCAP and start a new cmdtool window from that shell. +The bash command-line editing should behave better in the new +cmdtool. If this works, you can put the assignment to TERMCAP +in your bashrc file. + +F2) I built bash on Solaris 2. Why do globbing expansions and filename + completion chop off the first few characters of each filename? + +This is the consequence of building bash on SunOS 5 and linking +with the libraries in /usr/ucblib, but using the definitions +and structures from files in /usr/include. + +The actual conflict is between the dirent structure in +/usr/include/dirent.h and the struct returned by the version of +`readdir' in libucb.a (a 4.3-BSD style `struct direct'). + +Make sure you've got /usr/ccs/bin ahead of /usr/ucb in your $PATH +when configuring and building bash. This will ensure that you +use /usr/ccs/bin/cc or acc instead of /usr/ucb/cc and that you +link with libc before libucb. + +If you have installed the Sun C compiler, you may also need to +put /usr/ccs/bin and /opt/SUNWspro/bin into your $PATH before +/usr/ucb. + +F3) Why does bash dump core after I interrupt username completion or + `~user' tilde expansion on a machine running NIS? + +This is a famous and long-standing bug in the SunOS YP (sorry, NIS) +client library, which is part of libc. + +The YP library code keeps static state -- a pointer into the data +returned from the server. When YP initializes itself (setpwent), +it looks at this pointer and calls free on it if it's non-null. +So far, so good. + +If one of the YP functions is interrupted during getpwent (the +exact function is interpretwithsave()), and returns NULL, the +pointer is freed without being reset to NULL, and the function +returns. The next time getpwent is called, it sees that this +pointer is non-null, calls free, and the bash free() blows up +because it's being asked to free freed memory. + +The traditional Unix mallocs allow memory to be freed multiple +times; that's probably why this has never been fixed. You can +run configure with the `--without-gnu-malloc' option to use +the C library malloc and avoid the problem. + +F4) I'm running SVR4.2. Why is the line erased every time I type `@'? + +The `@' character is the default `line kill' character in most +versions of System V, including SVR4.2. You can change this +character to whatever you want using `stty'. For example, to +change the line kill character to control-u, type + + stty kill ^U + +where the `^' and `U' can be two separate characters. + +F5) Why does bash report syntax errors when my C News scripts use a + redirection before a subshell command? + +The actual command in question is something like + + < file ( command ) + +According to the grammar given in the POSIX.2 standard, this construct +is, in fact, a syntax error. Redirections may only precede `simple +commands'. A subshell construct such as the above is one of the shell's +`compound commands'. A redirection may only follow a compound command. + +This affects the mechanical transformation of commands that use `cat' +to pipe a file into a command (a favorite Useless-Use-Of-Cat topic on +comp.unix.shell). While most commands of the form + + cat file | command + +can be converted to `< file command', shell control structures such as +loops and subshells require `command < file'. + +The file CWRU/sh-redir-hack in the bash distribution is an +(unofficial) patch to parse.y that will modify the grammar to +support this construct. It will not apply with `patch'; you must +modify parse.y by hand. Note that if you apply this, you must +recompile with -DREDIRECTION_HACK. This introduces a large +number of reduce/reduce conflicts into the shell grammar. + +F6) Why can't I use vi-mode editing on Red Hat Linux 6.1? + +The short answer is that Red Hat screwed up. + +The long answer is that they shipped an /etc/inputrc that only works +for emacs mode editing, and then screwed all the vi users by setting +INPUTRC to /etc/inputrc in /etc/profile. + +The short fix is to do one of the following: remove or rename +/etc/inputrc, set INPUTRC=~/.inputrc in ~/.bashrc (or .bash_profile, +but make sure you export it if you do), remove the assignment to +INPUTRC from /etc/profile, add + + set keymap emacs + +to the beginning of /etc/inputrc, or bracket the key bindings in +/etc/inputrc with these lines + + $if mode=emacs + [...] + $endif + +F7) Why do bash-2.05a and bash-2.05b fail to compile `printf.def' on + HP/UX 11.x? + +HP/UX's support for long double is imperfect at best. + +GCC will support it without problems, but the HP C library functions +like strtold(3) and printf(3) don't actually work with long doubles. +HP implemented a `long_double' type as a 4-element array of 32-bit +ints, and that is what the library functions use. The ANSI C +`long double' type is a 128-bit floating point scalar. + +The easiest fix, until HP fixes things up, is to edit the generated +config.h and #undef the HAVE_LONG_DOUBLE line. After doing that, +the compilation should complete successfully. + +Section G: How can I get bash to do certain common things? + +G1) How can I get bash to read and display eight-bit characters? + +This is a process requiring several steps. + +First, you must ensure that the `physical' data path is a full eight +bits. For xterms, for example, the `vt100' resources `eightBitInput' +and `eightBitOutput' should be set to `true'. + +Once you have set up an eight-bit path, you must tell the kernel and +tty driver to leave the eighth bit of characters alone when processing +keyboard input. Use `stty' to do this: + + stty cs8 -istrip -parenb + +For old BSD-style systems, you can use + + stty pass8 + +You may also need + + stty even odd + +Finally, you need to tell readline that you will be inputting and +displaying eight-bit characters. You use readline variables to do +this. These variables can be set in your .inputrc or using the bash +`bind' builtin. Here's an example using `bind': + + bash$ bind 'set convert-meta off' + bash$ bind 'set meta-flag on' + bash$ bind 'set output-meta on' + +The `set' commands between the single quotes may also be placed +in ~/.inputrc. + +The script examples/scripts.noah/meta.bash encapsulates the bind +commands in a shell function. + +G2) How do I write a function `x' to replace builtin command `x', but + still invoke the command from within the function? + +This is why the `command' and `builtin' builtins exist. The +`command' builtin executes the command supplied as its first +argument, skipping over any function defined with that name. The +`builtin' builtin executes the builtin command given as its first +argument directly. + +For example, to write a function to replace `cd' that writes the +hostname and current directory to an xterm title bar, use +something like the following: + + cd() + { + builtin cd "$@" && xtitle "$HOST: $PWD" + } + +This could also be written using `command' instead of `builtin'; +the version above is marginally more efficient. + +G3) How can I find the value of a shell variable whose name is the value + of another shell variable? + +Versions of Bash newer than Bash-2.0 support this directly. You can use + + ${!var} + +For example, the following sequence of commands will echo `z': + + var1=var2 + var2=z + echo ${!var1} + +For sh compatibility, use the `eval' builtin. The important +thing to remember is that `eval' expands the arguments you give +it again, so you need to quote the parts of the arguments that +you want `eval' to act on. + +For example, this expression prints the value of the last positional +parameter: + + eval echo \"\$\{$#\}\" + +The expansion of the quoted portions of this expression will be +deferred until `eval' runs, while the `$#' will be expanded +before `eval' is executed. In versions of bash later than bash-2.0, + + echo ${!#} + +does the same thing. + +This is not the same thing as ksh93 `nameref' variables, though the syntax +is similar. I may add namerefs in a future bash version. + +G4) How can I make the bash `time' reserved word print timing output that + looks like the output from my system's /usr/bin/time? + +The bash command timing code looks for a variable `TIMEFORMAT' and +uses its value as a format string to decide how to display the +timing statistics. + +The value of TIMEFORMAT is a string with `%' escapes expanded in a +fashion similar in spirit to printf(3). The manual page explains +the meanings of the escape sequences in the format string. + +If TIMEFORMAT is not set, bash acts as if the following assignment had +been performed: + + TIMEFORMAT=$'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS' + +The POSIX.2 default time format (used by `time -p command') is + + TIMEFORMAT=$'real %2R\nuser %2U\nsys %2S' + +The BSD /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\t%1R real\t%1U user\t%1S sys' + +The System V /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\nreal\t%1R\nuser\t%1U\nsys\t%1S' + +The ksh format can be emulated with: + + TIMEFORMAT=$'\nreal\t%2lR\nuser\t%2lU\nsys\t%2lS' + +G5) How do I get the current directory into my prompt? + +Bash provides a number of backslash-escape sequences which are expanded +when the prompt string (PS1 or PS2) is displayed. The full list is in +the manual page. + +The \w expansion gives the full pathname of the current directory, with +a tilde (`~') substituted for the current value of $HOME. The \W +expansion gives the basename of the current directory. To put the full +pathname of the current directory into the path without any tilde +subsitution, use $PWD. Here are some examples: + + PS1='\w$ ' # current directory with tilde + PS1='\W$ ' # basename of current directory + PS1='$PWD$ ' # full pathname of current directory + +The single quotes are important in the final example to prevent $PWD from +being expanded when the assignment to PS1 is performed. + +G6) How can I rename "*.foo" to "*.bar"? + +Use the pattern removal functionality described in D3. The following `for' +loop will do the trick: + + for f in *.foo; do + mv $f ${f%foo}bar + done + +G7) How can I translate a filename from uppercase to lowercase? + +The script examples/functions/lowercase, originally written by John DuBois, +will do the trick. The converse is left as an exercise. + +G8) How can I write a filename expansion (globbing) pattern that will match + all files in the current directory except "." and ".."? + +You must have set the `extglob' shell option using `shopt -s extglob' to use +this: + + echo .!(.|) * + +A solution that works without extended globbing is given in the Unix Shell +FAQ, posted periodically to comp.unix.shell. + +Section H: Where do I go from here? + +H1) How do I report bugs in bash, and where should I look for fixes and + advice? + +Use the `bashbug' script to report bugs. It is built and +installed at the same time as bash. It provides a standard +template for reporting a problem and automatically includes +information about your configuration and build environment. + +`bashbug' sends its reports to bug-bash@gnu.org, which +is a large mailing list gatewayed to the usenet newsgroup gnu.bash.bug. + +Bug fixes, answers to questions, and announcements of new releases +are all posted to gnu.bash.bug. Discussions concerning bash features +and problems also take place there. + +To reach the bash maintainers directly, send mail to +bash-maintainers@gnu.org. + +H2) What kind of bash documentation is there? + +First, look in the doc directory in the bash distribution. It should +contain at least the following files: + +bash.1 an extensive, thorough Unix-style manual page +builtins.1 a manual page covering just bash builtin commands +bashref.texi a reference manual in GNU tex`info format +bashref.info an info version of the reference manual +FAQ this file +article.ms text of an article written for The Linux Journal +readline.3 a man page describing readline + +Postscript, HTML, and ASCII files created from the above source are +available in the documentation distribution. + +There is additional documentation available for anonymous FTP from host +ftp.cwru.edu in the `pub/bash' directory. + +Cameron Newham and Bill Rosenblatt have written a book on bash, published +by O'Reilly and Associates. The book is based on Bill Rosenblatt's Korn +Shell book. The title is ``Learning the Bash Shell'', and the ISBN number +of the third edition, published in March, 2005, is 0-596-00965-8. Look for +it in fine bookstores near you. This edition of the book has been updated +to cover bash-3.0. + +The GNU Bash Reference Manual has been published as a printed book by +Network Theory Ltd (Paperback, ISBN: 0-9541617-7-7, Feb 2003). It covers +bash-2.0 and is available from most online bookstores (see +http://www.network-theory.co.uk/bash/manual/ for details). The publisher +will donate $1 to the Free Software Foundation for each copy sold. + +Arnold Robbins and Nelson Beebe have written ``Classic Shell Scripting'', +published by O'Reilly. The first edition, with ISBN number 0-596-00595-4, +was published in May, 2005. + +Chris F. A.

It is an implementation of +the Posix 1003.2 shell standard, and resembles the Korn and System V +shells. + +Bash contains a number of enhancements over those shells, both +for interactive use and shell programming. Features geared +toward interactive use include command line editing, command +history, job control, aliases, and prompt expansion. Programming +features include additional variable expansions, shell +arithmetic, and a number of variables and options to control +shell behavior. + +Bash was originally written by Brian Fox of the Free Software +Foundation. The current developer and maintainer is Chet Ramey +of Case Western Reserve University. + +A2) What's the latest version? + +The latest version is 2.05a, first made available on Thursday, 15 +November, 2001. + +A3) Where can I get it? + +Bash is the GNU project's shell, and so is available from the +master GNU archive site, ftp.gnu.org, and its mirrors. The +latest version is also available for FTP from ftp.cwru.edu. +The following URLs tell how to get version 2.05a: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-2.05a.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-2.05a.tar.gz + +Formatted versions of the documentation are available with the URLs: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-doc-2.05a.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-doc-2.05a.tar.gz + +A4) On what machines will bash run? + +Bash has been ported to nearly every version of UNIX. All you +should have to do to build it on a machine for which a port +exists is to type `configure' and then `make'. The build process +will attempt to discover the version of UNIX you have and tailor +itself accordingly, using a script created by GNU autoconf. + +More information appears in the file `INSTALL' in the distribution. + +The Bash web page (http://cnswww.cns.cwru.edu/~chet/bash/bashtop.html) +explains how to obtain binary versions of bash for most of the major +commercial Unix systems. + +A5) Will bash run on operating systems other than Unix? + +Configuration specifics for Unix-like systems such as QNX and +LynxOS are included in the distribution. Bash-2.05 and later +versions should compile and run on Minix 2.0 (patches were +contributed), but I don't believe anyone has built bash-2.x on +earlier Minix versions yet. + +Bash has been ported to versions of Windows implementing the Win32 +programming interface. This includes Windows 95 and Windows NT. +The port was done by Cygnus Solutions as part of their CYGWIN +project. For more information about the project, look at the URLs + +http://www.cygwin.com/ +http://sourceware.cygnus.com/cygwin + +Cygnus originally ported bash-1.14.7, and that port was part of their +early GNU-Win32 (the original name) releases. Cygnus has also done a +port of bash-2.05 to the CYGWIN environment, and it is available as +part of their current release. + +Bash-2.05a should require no local Cygnus changes to build and run under +CYGWIN. + +The Cygnus port works only on Intel machines. There is a port of bash +(I don't know which version) to the alpha/NT environment available from + +ftp://ftp.gnustep.org//pub/win32/bash-alpha-nt-1.01.tar.gz + +DJ Delorie has a port of bash-2.x which runs under MS-DOS, as part +of the DJGPP project. For more information on the project, see + +http://www.delorie.com/djgpp/ + +I have been told that the original DJGPP port was done by Daisuke Aoyama. + +Mark Elbrecht has sent me notice that bash-2.04 +is available for DJGPP V2. The files are available as: + +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204b.zip binary +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204d.zip documentation +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204s.zip source + +Mark has begun to work with bash-2.05, but I don't know the status. + +Ports of bash-1.12 and bash-2.0 are available for OS/2 from + +ftp://hobbes.nmsu.edu/pub/os2/util/shell/bash_112.zip +ftp://hobbes.nmsu.edu/pub/os2/util/shell/bash-2.0(253).zip + +I haven't looked at either, but the second appears to be a binary-only +distribution. Beware. + +I have received word that Bash (I'm not sure which version, but I +believe that it's at least bash-2.02.1) is the standard shell on +BeOS. + +A6) How can I build bash with gcc? + +Bash configures to use gcc by default if it is available. Read the +file INSTALL in the distribution for more information. + +A7) How can I make bash my login shell? + +Some machines let you use `chsh' to change your login shell. Other +systems use `passwd -s' or `passwd -e'. If one of these works for +you, that's all you need. Note that many systems require the full +pathname to a shell to appear in /etc/shells before you can make it +your login shell. For this, you may need the assistance of your +friendly local system administrator. + +If you cannot do this, you can still use bash as your login shell, but +you need to perform some tricks. The basic idea is to add a command +to your login shell's startup file to replace your login shell with +bash. + +For example, if your login shell is csh or tcsh, and you have installed +bash in /usr/gnu/bin/bash, add the following line to ~/.login: + + if ( -f /usr/gnu/bin/bash ) exec /usr/gnu/bin/bash --login + +(the `--login' tells bash that it is a login shell). + +It's not a good idea to put this command into ~/.cshrc, because every +csh you run without the `-f' option, even ones started to run csh scripts, +reads that file. If you must put the command in ~/.cshrc, use something +like + + if ( $?prompt ) exec /usr/gnu/bin/bash --login + +to ensure that bash is exec'd only when the csh is interactive. + +If your login shell is sh or ksh, you have to do two things. + +First, create an empty file in your home directory named `.bash_profile'. +The existence of this file will prevent the exec'd bash from trying to +read ~/.profile, and re-execing itself over and over again. ~/.bash_profile +is the first file bash tries to read initialization commands from when +it is invoked as a login shell. + +Next, add a line similar to the above to ~/.profile: + + [ -f /usr/gnu/bin/bash ] && exec /usr/gnu/bin/bash --login + +This will cause login shells to replace themselves with bash running as +a login shell. Once you have this working, you can copy your initialization +code from ~/.profile to ~/.bash_profile. + +I have received word that the recipe supplied above is insufficient for +machines running CDE. CDE has a maze of twisty little startup files, all +slightly different. + +If you cannot change your login shell in the password file to bash, you +will have to (apparently) live with CDE using the shell in the password +file to run its startup scripts. If you have changed your shell to bash, +there is code in the CDE startup files (on Solaris, at least) that attempts +to do the right thing. It is, however, often broken, and may require that +you use the $BASH_ENV trick described below. + +`dtterm' claims to use $SHELL as the default program to start, so if you +can change $SHELL in the CDE startup files, you should be able to use bash +in your terminal windows. + +Setting DTSOURCEPROFILE in ~/.dtprofile will cause the `Xsession' program +to read your login shell's startup files. You may be able to use bash for +the rest of the CDE programs by setting SHELL to bash in ~/.dtprofile as +well, but I have not tried this. + +You can use the above `exec' recipe to start bash when not logging in with +CDE by testing the value of the DT variable: + + if [ -n "$DT" ]; then + [ -f /usr/gnu/bin/bash ] && exec /usr/gnu/bin/bash --login + fi + +If CDE starts its shells non-interactively during login, the login shell +startup files (~/.profile, ~/.bash_profile) will not be sourced at login. +To get around this problem, append a line similar to the following to your +~/.dtprofile: + + BASH_ENV=${HOME}/.bash_profile ; export BASH_ENV + +and add the following line to the beginning of ~/.bash_profile: + + unset BASH_ENV + +A8) I just changed my login shell to bash, and now I can't FTP into my + machine. Why not? + +You must add the full pathname to bash to the file /etc/shells. As +noted in the answer to the previous question, many systems require +this before you can make bash your login shell. + +Most versions of ftpd use this file to prohibit `special' users +such as `uucp' and `news' from using FTP. + +A9) What's the `POSIX 1003.2 standard'? + +POSIX is a name originally coined by Richard Stallman for a +family of open system standards based on UNIX. There are a +number of aspects of UNIX under consideration for +standardization, from the basic system services at the system +call and C library level to applications and tools to system +administration and management. Each area of standardization is +assigned to a working group in the 1003 series. + +The POSIX Shell and Utilities standard has been developed by IEEE +Working Group 1003.2 (POSIX.2). It concentrates on the command +interpreter interface and utility programs commonly executed from +the command line or by other programs. An initial version of the +standard has been approved and published by the IEEE, and work is +currently underway to update it. + +Bash is concerned with the aspects of the shell's behavior +defined by POSIX.2. The shell command language has of course +been standardized, including the basic flow control and program +execution constructs, I/O redirection and pipelining, argument +handling, variable expansion, and quoting. + +The `special' builtins, which must be implemented as part of the +shell to provide the desired functionality, are specified as +being part of the shell; examples of these are `eval' and +`export'. Other utilities appear in the sections of POSIX.2 not +devoted to the shell which are commonly (and in some cases must +be) implemented as builtin commands, such as `read' and `test'. +POSIX.2 also specifies aspects of the shell's interactive +behavior as part of the UPE, including job control and command +line editing. Only vi-style line editing commands have been +standardized; emacs editing commands were left out due to +objections. + +The Open Group has made an older version of its Single Unix +Specification (version 2), which is very similar to POSIX.2, +available on the web at + +http://www.opengroup.org/onlinepubs/007908799/ + +A10) What is the bash `posix mode'? + +Although bash is an implementation of the POSIX.2 shell +specification, there are areas where the bash default behavior +differs from that spec. The bash `posix mode' changes the bash +behavior in these areas so that it obeys the spec more closely. + +Posix mode is entered by starting bash with the --posix option or +executing `set -o posix' after bash is running. + +The specific aspects of bash which change when posix mode is +active are listed in the file CWRU/POSIX.NOTES in the bash +distribution. They are also listed in a section in the Bash +Reference Manual. + +Section B: The latest version + +B1) What's new in version 2.05a? + +The raison d'etre for bash-2.05a is to make an intermediate release +containing principally bug fixes (some very good work was done and +contributed after bash-2.05 was released) available before I start to +work on the major new features to be available in the next release +(bash-2.06 or bash-3.0 or whatever I tag it). As such, there are +only a few relatively minor new features. + +Bash-2.05a contains the following new features (see the manual page for +complete descriptions and the CHANGES and NEWS files in the bash-2.05a +distribution): + +o The `printf' builtin has undergone major work + +o There is a new read-only `shopt' option: login_shell, which is set by + login shells and unset otherwise + +o New `\A' prompt string escape sequence; expanding to time in 24-hour + HH:MM format + +o New `-A group/-g' option to complete and compgen; goes group name + completion + +o New [+-]O invocation option to set and unset `shopt' options at startup + +o ksh-like `ERR' trap + +o `for' loops now allow empty word lists after the `in' reserved word + +o new `hard' and `soft' arguments for the `ulimit' builtin + +o Readline can be configured to place the user at the same point on the line + when retrieving commands from the history list + +o Readline can be configured to skip `hidden' files (filenames with a leading + `.' on Unix) when performing completion + +A short feature history dating from bash-2.0: + +Bash-2.05 introduced the following new features: + +o This version has once again reverted to using locales and strcoll(3) when + processing pattern matching bracket expressions, as POSIX requires. +o Added a new `--init-file' invocation argument as a synonym for `--rcfile', + per the new GNU coding standards. +o The /dev/tcp and /dev/udp redirections now accept service names as well as + port numbers. +o `complete' and `compgen' now take a `-o value' option, which controls some + of the aspects of that compspec. Valid values are: + + default - perform bash default completion if programmable + completion produces no matches + dirnames - perform directory name completion if programmable + completion produces no matches + filenames - tell readline that the compspec produces filenames, + so it can do things like append slashes to + directory names and suppress trailing spaces +o A new loadable builtin, realpath, which canonicalizes and expands symlinks + in pathname arguments. +o When `set' is called without options, it prints function defintions in a + way that allows them to be reused as input. This affects `declare' and + `declare -p' as well. This only happens when the shell is not in POSIX + mode, since POSIX.2 forbids this behavior. + +Bash-2.04 introduced the following new features: + +o Programmable word completion with the new `complete' and `compgen' builtins; + examples are provided in examples/complete/complete-examples +o `history' has a new `-d' option to delete a history entry +o `bind' has a new `-x' option to bind key sequences to shell commands +o The prompt expansion code has new `\j' and `\l' escape sequences +o The `no_empty_cmd_completion' shell option, if enabled, inhibits + command completion when TAB is typed on an empty line +o `help' has a new `-s' option to print a usage synopsis +o New arithmetic operators: var++, var--, ++var, --var, expr1,expr2 (comma) +o New ksh93-style arithmetic for command: + for ((expr1 ; expr2; expr3 )); do list; done +o `read' has new options: `-t', `-n', `-d', `-s' +o The redirection code handles several filenames specially: /dev/fd/N, + /dev/stdin, /dev/stdout, /dev/stderr +o The redirection code now recognizes /dev/tcp/HOST/PORT and + /dev/udp/HOST/PORT and tries to open a TCP or UDP socket, respectively, + to the specified port on the specified host +o The ${!prefix*} expansion has been implemented +o A new FUNCNAME variable, which expands to the name of a currently-executing + function +o The GROUPS variable is no longer readonly +o A new shopt `xpg_echo' variable, to control the behavior of echo with + respect to backslash-escape sequences at runtime +o The NON_INTERACTIVE_LOGIN_SHELLS #define has returned + +The version of Readline released with Bash-2.04, Readline-4.1, had several +new features as well: + +o Parentheses matching is always compiled into readline, and controllable + with the new `blink-matching-paren' variable +o The history-search-forward and history-search-backward functions now leave + point at the end of the line when the search string is empty, like + reverse-search-history, and forward-search-history +o A new function for applications: rl_on_new_line_with_prompt() +o New variables for applications: rl_already_prompted, and rl_gnu_readline_p + + +Bash-2.03 had very few new features, in keeping with the convention +that odd-numbered releases provide mainly bug fixes.

+ +D1) Why does bash run a different version of `command' than + `which command' says it will? + +On many systems, `which' is actually a csh script that assumes +you're running csh. In tcsh, `which' and its cousin `where' +are builtins. On other Unix systems, `which' is a perl script +that uses the PATH environment variable. + +The csh script version reads the csh startup files from your +home directory and uses those to determine which `command' will +be invoked. Since bash doesn't use any of those startup files, +there's a good chance that your bash environment differs from +your csh environment. The bash `type' builtin does everything +`which' does, and will report correct results for the running +shell. If you're really wedded to the name `which', try adding +the following function definition to your .bashrc: + + which() + { + builtin type "$@" + } + +If you're moving from tcsh and would like to bring `where' along +as well, use this function: + + where() + { + builtin type -a "$@" + } + +D2) Why doesn't bash treat brace expansions exactly like csh? + +The only difference between bash and csh brace expansion is that +bash requires a brace expression to contain at least one unquoted +comma if it is to be expanded. Any brace-surrounded word not +containing an unquoted comma is left unchanged by the brace +expansion code. This affords the greatest degree of sh +compatibility. + +Bash, ksh, zsh, and pd-ksh all implement brace expansion this way. + +D3) Why doesn't bash have csh variable modifiers? + +Posix has specified a more powerful, albeit somewhat more cryptic, +mechanism cribbed from ksh, and bash implements it. + +${parameter%word} + Remove smallest suffix pattern. The WORD is expanded to produce + a pattern. It then expands to the value of PARAMETER, with the + smallest portion of the suffix matched by the pattern deleted. + + x=file.c + echo ${x%.c}.o + -->file.o + +${parameter%%word} + + Remove largest suffix pattern. The WORD is expanded to produce + a pattern. It then expands to the value of PARAMETER, with the + largest portion of the suffix matched by the pattern deleted. + + x=posix/src/std + echo ${x%%/*} + -->posix + +${parameter#word} + Remove smallest prefix pattern. The WORD is expanded to produce + a pattern. It then expands to the value of PARAMETER, with the + smallest portion of the prefix matched by the pattern deleted. + + x=$HOME/src/cmd + echo ${x#$HOME} + -->/src/cmd + +${parameter##word} + Remove largest prefix pattern.

We have provided +a shell script which does most of the work of conversion for you; +this script can be found in ./examples/misc/aliasconv.sh. Here is +how you use it: + +Start csh in the normal way for you. (e.g., `csh') + +Pipe the output of `alias' through `aliasconv.sh', saving the +results into `bash_aliases': + + alias | bash aliasconv.sh >bash_aliases + +Edit `bash_aliases', carefully reading through any created +functions. You will need to change the names of some csh specific +variables to the bash equivalents. The script converts $cwd to +$PWD, $term to $TERM, $home to $HOME, $user to $USER, and $prompt +to $PS1. You may also have to add quotes to avoid unwanted +expansion. + +For example, the csh alias: + + alias cd 'cd \!*; echo $cwd' + +is converted to the bash function: + + cd () { command cd "$@"; echo $PWD ; } + +The only thing that needs to be done is to quote $PWD: + + cd () { command cd "$@"; echo "$PWD" ; } + +Merge the edited file into your ~/.bashrc. + +There is an additional, more ambitious, script in +examples/misc/cshtobash that attempts to convert your entire csh +environment to its bash equivalent. This script can be run as +simply `cshtobash' to convert your normal interactive +environment, or as `cshtobash ~/.login' to convert your login +environment. + +D5) How can I pipe standard output and standard error from one command to + another, like csh does with `|&'? + +Use + command 2>&1 | command2 + +The key is to remember that piping is performed before redirection, so +file descriptor 1 points to the pipe when it is duplicated onto file +descriptor 2. + +D6) Now that I've converted from ksh to bash, are there equivalents to + ksh features like autoloaded functions and the `whence' command? + +There are features in ksh-88 and ksh-93 that do not have direct bash +equivalents. Most, however, can be emulated with very little trouble. + +ksh-88 feature Bash equivalent +-------------- --------------- +compiled-in aliases set up aliases in .bashrc; some ksh aliases are + bash builtins (hash, history, type) +coprocesses named pipe pairs (one for read, one for write) +typeset +f declare -F +cd, print, whence function substitutes in examples/functions/kshenv +autoloaded functions examples/functions/autoload is the same as typeset -fu +read var?prompt read -p prompt var + +ksh-93 feature Bash equivalent +-------------- --------------- +sleep, getconf Bash has loadable versions in examples/loadables +${.sh.version} $BASH_VERSION +print -f printf +hist alias fc=hist +$HISTEDIT $FCEDIT + +Section E: How can I get bash to do certain things, and why does bash do + things the way it does? + +E1) Why is the bash builtin `test' slightly different from /bin/test? + +The specific example used here is [ ! x -o x ], which is false. + +Bash's builtin `test' implements the Posix.2 spec, which can be +summarized as follows (the wording is due to David Korn): + +Here is the set of rules for processing test arguments. + + 0 Args: False + 1 Arg: True iff argument is not null. + 2 Args: If first arg is !, True iff second argument is null. + If first argument is unary, then true if unary test is true + Otherwise error. + 3 Args: If second argument is a binary operator, do binary test of $1 $3 + If first argument is !, negate two argument test of $2 $3 + If first argument is `(' and third argument is `)', do the + one-argument test of the second argument. + Otherwise error. + 4 Args: If first argument is !, negate three argument test of $2 $3 $4. + Otherwise unspecified + 5 or more Args: unspecified. (Historical shells would use their + current algorithm). + +The operators -a and -o are considered binary operators for the purpose +of the 3 Arg case. + +As you can see, the test becomes (not (x or x)), which is false. + +E2) Why does bash sometimes say `Broken pipe'? + +If a sequence of commands appears in a pipeline, and one of the +reading commands finishes before the writer has finished, the +writer receives a SIGPIPE signal. Many other shells special-case +SIGPIPE as an exit status in the pipeline and do not report it. +For example, in: + + ps -aux | head + +`head' can finish before `ps' writes all of its output, and ps +will try to write on a pipe without a reader. In that case, bash +will print `Broken pipe' to stderr when ps is killed by a +SIGPIPE. + +You can build a version of bash that will not report SIGPIPE errors +by uncommenting the definition of DONT_REPORT_SIGPIPE in the file +config-top.h. + +E3) When I have terminal escape sequences in my prompt, why does bash + wrap lines at the wrong column? + +Readline, the line editing library that bash uses, does not know +that the terminal escape sequences do not take up space on the +screen. The redisplay code assumes, unless told otherwise, that +each character in the prompt is a `printable' character that +takes up one character position on the screen. + +You can use the bash prompt expansion facility (see the PROMPTING +section in the manual page) to tell readline that sequences of +characters in the prompt strings take up no screen space. + +Use the \[ escape to begin a sequence of non-printing characters, +and the \] escape to signal the end of such a sequence. + +E4) If I pipe the output of a command into `read variable', why doesn't + the output show up in $variable when the read command finishes? + +This has to do with the parent-child relationship between Unix +processes. It affects all commands run in pipelines, not just +simple calls to `read'. For example, piping a command's output +into a `while' loop that repeatedly calls `read' will result in +the same behavior. + +Each element of a pipeline runs in a separate process, a child of +the shell running the pipeline. A subprocess cannot affect its +parent's environment. When the `read' command sets the variable +to the input, that variable is set only in the subshell, not the +parent shell. When the subshell exits, the value of the variable +is lost. + +Many pipelines that end with `read variable' can be converted +into command substitutions, which will capture the output of +a specified command. The output can then be assigned to a +variable: + + grep ^gnu /usr/lib/news/active | wc -l | read ngroup + +can be converted into + + ngroup=$(grep ^gnu /usr/lib/news/active | wc -l) + +This does not, unfortunately, work to split the text among +multiple variables, as read does when given multiple variable +arguments. If you need to do this, you can either use the +command substitution above to read the output into a variable +and chop up the variable using the bash pattern removal +expansion operators or use some variant of the following +approach. + +Say /usr/local/bin/ipaddr is the following shell script: + +#! /bin/sh +host `hostname` | awk '/address/ {print $NF}' + +Instead of using + + /usr/local/bin/ipaddr | read A B C D + +to break the local machine's IP address into separate octets, use + + OIFS="$IFS" + IFS=. + set -- $(/usr/local/bin/ipaddr) + IFS="$OIFS" + A="$1" B="$2" C="$3" D="$4" + +Beware, however, that this will change the shell's positional +parameters. If you need them, you should save them before doing +this. + +This is the general approach -- in most cases you will not need to +set $IFS to a different value. + +Some other user-supplied alternatives include: + +read A B C D << HERE + $(IFS=.; echo $(/usr/local/bin/ipaddr)) +HERE + +and, where process substitution is available, + +read A B C D < <(IFS=.; echo $(/usr/local/bin/ipaddr)) + +E5) I have a bunch of shell scripts that use backslash-escaped characters + in arguments to `echo'. Bash doesn't interpret these characters. Why + not, and how can I make it understand them? + +This is the behavior of echo on most Unix System V machines. + +The bash builtin `echo' is modeled after the 9th Edition +Research Unix version of `echo'. It does not interpret +backslash-escaped characters in its argument strings by default; +it requires the use of the -e option to enable the +interpretation. The System V echo provides no way to disable the +special characters; the bash echo has a -E option to disable +them. + +There is a configuration option that will make bash behave like +the System V echo and interpret things like `\t' by default. Run +configure with the --enable-xpg-echo-default option to turn this +on. Be aware that this will cause some of the tests run when you +type `make tests' to fail. + +There is a shell option, `xpg_echo', settable with `shopt' that will +change the behavior of echo at runtime. Enabling this option turns +on expansion of backslash-escape sequences. + +E6) Why doesn't a while or for loop get suspended when I type ^Z? + +This is a consequence of how job control works on Unix. The only +thing that can be suspended is the process group. This is a single +command or pipeline of commands that the shell forks and executes. + +When you run a while or for loop, the only thing that the shell forks +and executes are any commands in the while loop test and commands in +the loop bodies. These, therefore, are the only things that can be +suspended when you type ^Z. + +If you want to be able to stop the entire loop, you need to put it +within parentheses, which will force the loop into a subshell that +may be stopped (and subsequently restarted) as a single unit. + +E7) What about empty for loops in Makefiles? + +It's fairly common to see constructs like this in automatically-generated +Makefiles: + +SUBDIRS = @SUBDIRS@ + + ... + +subdirs-clean: + for d in ${SUBDIRS}; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +When SUBDIRS is empty, this results in a command like this being passed to +bash: + + for d in ; do + ( cd $d && ${MAKE} ${MFLAGS} clean ) + done + +In versions of bash before bash-2.05a, this was a syntax error. If the +reserved word `in' was present, a word must follow it before the semicolon +or newline. The language in the manual page referring to the list of words +being empty referred to the list after it is expanded. These versions of +bash required that there be at least one word following the `in' when the +construct was parsed. + +The idiomatic Makefile solution is something like: + +SUBDIRS = @SUBDIRS@ + +subdirs-clean: + subdirs=$SUBDIRS ; for d in $$subdirs; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +The latest drafts of the updated POSIX standard have changed this: the +word list is no longer required. Bash versions 2.05a and later accept +the new syntax. + +E8) Why does the arithmetic evaluation code complain about `08'? + +The bash arithmetic evaluation code (used for `let', $(()), (()), and in +other places), interprets a leading `0' in numeric constants as denoting +an octal number, and a leading `0x' as denoting hexadecimal. This is +in accordance with the POSIX.2 spec, section 2.9.2.1, which states that +arithmetic constants should be handled as signed long integers as defined +by the ANSI/ISO C standard. + +The POSIX.2 interpretation committee has confirmed this: + +http://www.pasc.org/interps/unofficial/db/p1003.2/pasc-1003.2-173.html + +E9) Why does the pattern matching expression [A-Z]* match files beginning + with every letter except `z'? + +Bash-2.05 and later versions have reverted to the bash-2.03 behavior of +honoring the current locale setting when processing ranges within pattern +matching bracket expressions ([A-Z]). This is what POSIX.2 and SUSv3/XPG6 +specify. + +The behavior of the matcher in bash-2.05 and later versions depends on the +current LC_COLLATE setting. Setting this variable to `C' or `POSIX' will +result in the traditional behavior ([A-Z] matches all uppercase ASCII +characters). Many other locales, including the en_US locale (the default +on many US versions of Linux) collate the upper and lower case letters like +this: + + AaBb...Zz + +which means that [A-Z] matches every letter except `z'. Others collate like + + aAbBcC...zZ + +which means that [A-Z] matches every letter except `a'. + +The portable way to specify upper case letters is [:upper:] instead of +A-Z; lower case may be specified as [:lower:] instead of a-z. + +Look at the manual pages for setlocale(3), strcoll(3), and, if it is +present, locale(1). If you have locale(1), you can use it to find +your current locale information even if you do not have any of the +LC_ variables set. + +My advice is to put + + export LC_COLLATE=C + +into /etc/profile and inspect any shell scripts run from cron for +constructs like [A-Z]. This will prevent things like + + rm [A-Z]* + +from removing every file in the current directory except those beginning +with `z' and still allow individual users to change the collation order. +Users may put the above command into their own profiles as well, of course. + +E10) Why does `cd //' leave $PWD as `//'? + +POSIX.2, in its description of `cd', says that *three* or more leading +slashes may be replaced with a single slash when canonicalizing the +current working directory. + +This is, I presume, for historical compatibility. Certain versions of +Unix, and early network file systems, used paths of the form +//hostname/path to access `path' on server `hostname'. + +Section F: Things to watch out for on certain Unix versions + +F1) Why can't I use command line editing in my `cmdtool'? + +The problem is `cmdtool' and bash fighting over the input. When +scrolling is enabled in a cmdtool window, cmdtool puts the tty in +`raw mode' to permit command-line editing using the mouse for +applications that cannot do it themselves. As a result, bash and +cmdtool each try to read keyboard input immediately, with neither +getting enough of it to be useful. + +This mode also causes cmdtool to not implement many of the +terminal functions and control sequences appearing in the +`sun-cmd' termcap entry. For a more complete explanation, see +that file examples/suncmd.termcap in the bash distribution. + +`xterm' is a better choice, and gets along with bash much more +smoothly. + +If you must use cmdtool, you can use the termcap description in +examples/suncmd.termcap. Set the TERMCAP variable to the terminal +description contained in that file, i.e. + +TERMCAP='Mu|sun-cmd:am:bs:km:pt:li#34:co#80:cl=^L:ce=\E[K:cd=\E[J:rs=\E[s:' + +Then export TERMCAP and start a new cmdtool window from that shell. +The bash command-line editing should behave better in the new +cmdtool. If this works, you can put the assignment to TERMCAP +in your bashrc file. + +F2) I built bash on Solaris 2. Why do globbing expansions and filename + completion chop off the first few characters of each filename? + +This is the consequence of building bash on SunOS 5 and linking +with the libraries in /usr/ucblib, but using the definitions +and structures from files in /usr/include. + +The actual conflict is between the dirent structure in +/usr/include/dirent.h and the struct returned by the version of +`readdir' in libucb.a (a 4.3-BSD style `struct direct'). + +Make sure you've got /usr/ccs/bin ahead of /usr/ucb in your $PATH +when configuring and building bash. This will ensure that you +use /usr/ccs/bin/cc or acc instead of /usr/ucb/cc and that you +link with libc before libucb. + +If you have installed the Sun C compiler, you may also need to +put /usr/ccs/bin and /opt/SUNWspro/bin into your $PATH before +/usr/ucb. + +F3) Why does bash dump core after I interrupt username completion or + `~user' tilde expansion on a machine running NIS? + +This is a famous and long-standing bug in the SunOS YP (sorry, NIS) +client library, which is part of libc. + +The YP library code keeps static state -- a pointer into the data +returned from the server. When YP initializes itself (setpwent), +it looks at this pointer and calls free on it if it's non-null. +So far, so good. + +If one of the YP functions is interrupted during getpwent (the +exact function is interpretwithsave()), and returns NULL, the +pointer is freed without being reset to NULL, and the function +returns. The next time getpwent is called, it sees that this +pointer is non-null, calls free, and the bash free() blows up +because it's being asked to free freed memory. + +The traditional Unix mallocs allow memory to be freed multiple +times; that's probably why this has never been fixed. You can +run configure with the `--without-gnu-malloc' option to use +the C library malloc and avoid the problem. + +F4) I'm running SVR4.2. Why is the line erased every time I type `@'? + +The `@' character is the default `line kill' character in most +versions of System V, including SVR4.2. You can change this +character to whatever you want using `stty'. For example, to +change the line kill character to control-u, type + + stty kill ^U + +where the `^' and `U' can be two separate characters. + +F5) Why does bash report syntax errors when my C News scripts use a + redirection before a subshell command? + +The actual command in question is something like + + < file ( command ) + +According to the grammar given in the POSIX.2 standard, this construct +is, in fact, a syntax error. Redirections may only precede `simple +commands'. A subshell construct such as the above is one of the shell's +`compound commands'. A redirection may only follow a compound command. + +This affects the mechanical transformation of commands that use `cat' +to pipe a file into a command (a favorite Useless-Use-Of-Cat topic on +comp.unix.shell). While most commands of the form + + cat file | command + +can be converted to `< file command', shell control structures such as +loops and subshells require `command < file'. + +The file CWRU/sh-redir-hack in the bash-2.05a distribution is an +(unofficial) patch to parse.y that will modify the grammar to +support this construct. It will not apply with `patch'; you must +modify parse.y by hand. Note that if you apply this, you must +recompile with -DREDIRECTION_HACK. This introduces a large +number of reduce/reduce conflicts into the shell grammar. + +F6) Why can't I use vi-mode editing on Red Hat Linux 6.1? + +The short answer is that Red Hat screwed up. + +The long answer is that they shipped an /etc/inputrc that only works +for emacs mode editing, and then screwed all the vi users by setting +INPUTRC to /etc/inputrc in /etc/profile. + +The short fix is to do one of the following: remove or rename +/etc/inputrc, set INPUTRC=~/.inputrc in ~/.bashrc (or .bash_profile, +but make sure you export it if you do), remove the assignment to +INPUTRC from /etc/profile, add + + set keymap emacs + +to the beginning of /etc/inputrc, or bracket the key bindings in +/etc/inputrc with these lines + + $if mode=emacs + [...] + $endif + +F7) Why does bash-2.05a fail to compile `printf.def' on HP/UX 11.x? + +HP/UX's support for long double is imperfect at best. + +GCC will support it without problems, but the HP C library functions +like strtold(3) and printf(3) don't actually work with long doubles. +HP implemented a `long_double' type as a 4-element array of 32-bit +ints, and that is what the library functions use. The ANSI C +`long double' type is a 128-bit floating point scalar. + +The easiest fix, until HP fixes things up, is to edit the generated +config.h and #undef the HAVE_LONG_DOUBLE line. After doing that, +the compilation should complete successfully. + +Section G: How can I get bash to do certain common things? + +G1) How can I get bash to read and display eight-bit characters? + +This is a process requiring several steps. + +First, you must ensure that the `physical' data path is a full eight +bits. For xterms, for example, the `vt100' resources `eightBitInput' +and `eightBitOutput' should be set to `true'. + +Once you have set up an eight-bit path, you must tell the kernel and +tty driver to leave the eighth bit of characters alone when processing +keyboard input. Use `stty' to do this: + + stty cs8 -istrip -parenb + +For old BSD-style systems, you can use + + stty pass8 + +You may also need + + stty even odd + +Finally, you need to tell readline that you will be inputting and +displaying eight-bit characters. You use readline variables to do +this. These variables can be set in your .inputrc or using the bash +`bind' builtin. Here's an example using `bind': + + bash$ bind 'set convert-meta off' + bash$ bind 'set meta-flag on' + bash$ bind 'set output-meta on' + +The `set' commands between the single quotes may also be placed +in ~/.inputrc. + +G2) How do I write a function `x' to replace builtin command `x', but + still invoke the command from within the function? + +This is why the `command' and `builtin' builtins exist. The +`command' builtin executes the command supplied as its first +argument, skipping over any function defined with that name. The +`builtin' builtin executes the builtin command given as its first +argument directly. + +For example, to write a function to replace `cd' that writes the +hostname and current directory to an xterm title bar, use +something like the following: + + cd() + { + builtin cd "$@" && xtitle "$HOST: $PWD" + } + +This could also be written using `command' instead of `builtin'; +the version above is marginally more efficient. + +G3) How can I find the value of a shell variable whose name is the value + of another shell variable? + +Versions of Bash newer than Bash-2.0 support this directly. You can use + + ${!var} + +For example, the following sequence of commands will echo `z': + + var1=var2 + var2=z + echo ${!var1} + +For sh compatibility, use the `eval' builtin. The important +thing to remember is that `eval' expands the arguments you give +it again, so you need to quote the parts of the arguments that +you want `eval' to act on. + +For example, this expression prints the value of the last positional +parameter: + + eval echo \"\$\{$#\}\" + +The expansion of the quoted portions of this expression will be +deferred until `eval' runs, while the `$#' will be expanded +before `eval' is executed. In versions of bash later than bash-2.0, + + echo ${!#} + +does the same thing. + +This is not the same thing as ksh93 `nameref' variables, though the syntax +is similar. I may add namerefs in a future bash version. + +G4) How can I make the bash `time' reserved word print timing output that + looks like the output from my system's /usr/bin/time? + +The bash command timing code looks for a variable `TIMEFORMAT' and +uses its value as a format string to decide how to display the +timing statistics. + +The value of TIMEFORMAT is a string with `%' escapes expanded in a +fashion similar in spirit to printf(3). The manual page explains +the meanings of the escape sequences in the format string. + +If TIMEFORMAT is not set, bash acts as if the following assignment had +been performed: + + TIMEFORMAT=$'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS' + +The POSIX.2 default time format (used by `time -p command') is + + TIMEFORMAT=$'real %2R\nuser %2U\nsys %2S' + +The BSD /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\t%1R real\t%1U user\t%1S sys' + +The System V /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\nreal\t%1R\nuser\t%1U\nsys\t%1S' + +The ksh format can be emulated with: + + TIMEFORMAT=$'\nreal\t%2lR\nuser\t%2lU\nsys\t%2lS' + +G5) How do I get the current directory into my prompt? + +Bash provides a number of backslash-escape sequences which are expanded +when the prompt string (PS1 or PS2) is displayed. The full list is in +the manual page. + +The \w expansion gives the full pathname of the current directory, with +a tilde (`~') substituted for the current value of $HOME. The \W +expansion gives the basename of the current directory. To put the full +pathname of the current directory into the path without any tilde +subsitution, use $PWD. Here are some examples: + + PS1='\w$ ' # current directory with tilde + PS1='\W$ ' # basename of current directory + PS1='$PWD$ ' # full pathname of current directory + +The single quotes are important in the final example to prevent $PWD from +being expanded when the assignment to PS1 is performed. + +G6) How can I rename "*.foo" to "*.bar"? + +Use the pattern removal functionality described in D3. The following `for' +loop will do the trick: + + for f in *.foo; do + mv $f ${f%foo}bar + done + +G7) How can I translate a filename from uppercase to lowercase? + +The script examples/functions/lowercase, originally written by John DuBois, +will do the trick. The converse is left as an exercise. + +G8) How can I write a filename expansion (globbing) pattern that will match + all files in the current directory except "." and ".."? + +You must have set the `extglob' shell option using `shopt -s extglob' to use +this: + + echo .!(.|) * + +A solution that works without extended globbing is given in the Unix Shell +FAQ, posted periodically to comp.unix.shell. + +Section H: Where do I go from here? + +H1) How do I report bugs in bash, and where should I look for fixes and + advice? + +Use the `bashbug' script to report bugs. It is built and +installed at the same time as bash. It provides a standard +template for reporting a problem and automatically includes +information about your configuration and build environment. + +`bashbug' sends its reports to bug-bash@gnu.org, which +is a large mailing list gatewayed to the usenet newsgroup gnu.bash.bug. + +Bug fixes, answers to questions, and announcements of new releases +are all posted to gnu.bash.bug. Discussions concerning bash features +and problems also take place there. + +To reach the bash maintainers directly, send mail to +bash-maintainers@gnu.org. + +H2) What kind of bash documentation is there? + +First, look in the doc directory in the bash distribution. It should +contain at least the following files: + +bash.1 an extensive, thorough Unix-style manual page +builtins.1 a manual page covering just bash builtin commands +bashref.texi a reference manual in GNU tex`info format +bashref.info an info version of the reference manual +FAQ this file +article.ms text of an article written for The Linux Journal +readline.3 a man page describing readline + +Postscript, HTML, and ASCII files created from the above source are +available in the documentation distribution. + +There is additional documentation available for anonymous FTP from host +ftp.cwru.edu in the `pub/bash' directory. + +Cameron Newham and Bill Rosenblatt have written a book on bash, published +by O'Reilly and Associates. The book is based on Bill Rosenblatt's Korn +Shell book. The title is ``Learning the Bash Shell'', and the ISBN number +is 1-56592-147-X. Look for it in fine bookstores near you. This book +covers bash-1.14, but has an appendix describing some of the new features +in bash-2.0. + +A second edition of this book is available, published in January, 1998. +The ISBN number is 1-56592-347-2. Look for it in the same fine bookstores +or on the web. + +H3) What's coming in future versions? + +These are features I hope to include in a future version of bash. + +a better bash debugger (a minimally-tested version is included with bash-2.05a) +associative arrays +changes to the DEBUG trap to be compatible with ksh93 (which runs the +trap before each simple command, instead of after each one like previous +versions) +co-processes, but with a new-style syntax that looks like function declaration + +H4) What's on the bash `wish list' for future versions? + +These are features that may or may not appear in a future version of bash. + +breaking some of the shell functionality into embeddable libraries +a module system like zsh's, using dynamic loading like builtins +better internationalization using GNU `gettext' +an option to use external files for the long `help' text +date-stamped command history +a bash programmer's guide with a chapter on creating loadable builtins +a better loadable interface to perl with access to the shell builtins and + variables (contributions gratefully accepted) +ksh93-like `nameref' variables +ksh93-like `+=' variable assignment operator +ksh93-like `xx.yy' variables (including some of the .sh.* variables) and + associated disipline functions +Some of the new ksh93 pattern matching operators, like backreferencing + +H5) When will the next release appear? + +The next version will appear sometime in 2002.

It is an implementation of +the Posix 1003.2 shell standard, and resembles the Korn and System V +shells. + +Bash contains a number of enhancements over those shells, both +for interactive use and shell programming. Features geared +toward interactive use include command line editing, command +history, job control, aliases, and prompt expansion. Programming +features include additional variable expansions, shell +arithmetic, and a number of variables and options to control +shell behavior. + +Bash was originally written by Brian Fox of the Free Software +Foundation. The current developer and maintainer is Chet Ramey +of Case Western Reserve University. + +A2) What's the latest version? + +The latest version is 2.05b, first made available on Wednesday, 17 +July, 2002. + +A3) Where can I get it? + +Bash is the GNU project's shell, and so is available from the +master GNU archive site, ftp.gnu.org, and its mirrors. The +latest version is also available for FTP from ftp.cwru.edu. +The following URLs tell how to get version 2.05b: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-2.05b.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-2.05b.tar.gz + +Formatted versions of the documentation are available with the URLs: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-doc-2.05b.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-doc-2.05b.tar.gz + +A4) On what machines will bash run? + +Bash has been ported to nearly every version of UNIX. All you +should have to do to build it on a machine for which a port +exists is to type `configure' and then `make'. The build process +will attempt to discover the version of UNIX you have and tailor +itself accordingly, using a script created by GNU autoconf. + +More information appears in the file `INSTALL' in the distribution. + +The Bash web page (http://cnswww.cns.cwru.edu/~chet/bash/bashtop.html) +explains how to obtain binary versions of bash for most of the major +commercial Unix systems. + +A5) Will bash run on operating systems other than Unix? + +Configuration specifics for Unix-like systems such as QNX and +LynxOS are included in the distribution. Bash-2.05 and later +versions should compile and run on Minix 2.0 (patches were +contributed), but I don't believe anyone has built bash-2.x on +earlier Minix versions yet. + +Bash has been ported to versions of Windows implementing the Win32 +programming interface. This includes Windows 95 and Windows NT. +The port was done by Cygnus Solutions as part of their CYGWIN +project. For more information about the project, look at the URLs + +http://www.cygwin.com/ +http://sourceware.cygnus.com/cygwin + +Cygnus originally ported bash-1.14.7, and that port was part of their +early GNU-Win32 (the original name) releases. Cygnus has also done a +port of bash-2.05 to the CYGWIN environment, and it is available as +part of their current release. + +Bash-2.05b should require no local Cygnus changes to build and run under +CYGWIN. + +The Cygnus port works only on Intel machines. There is a port of bash +(I don't know which version) to the alpha/NT environment available from + +ftp://ftp.gnustep.org//pub/win32/bash-alpha-nt-1.01.tar.gz + +DJ Delorie has a port of bash-2.x which runs under MS-DOS, as part +of the DJGPP project. For more information on the project, see + +http://www.delorie.com/djgpp/ + +I have been told that the original DJGPP port was done by Daisuke Aoyama. + +Mark Elbrecht has sent me notice that bash-2.04 +is available for DJGPP V2. The files are available as: + +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204b.zip binary +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204d.zip documentation +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204s.zip source + +Mark has begun to work with bash-2.05, but I don't know the status. + +Ports of bash-1.12 and bash-2.0 are available for OS/2 from + +ftp://hobbes.nmsu.edu/pub/os2/util/shell/bash_112.zip +ftp://hobbes.nmsu.edu/pub/os2/util/shell/bash-2.0(253).zip + +I haven't looked at either, but the second appears to be a binary-only +distribution. Beware. + +I have received word that Bash (I'm not sure which version, but I +believe that it's at least bash-2.02.1) is the standard shell on +BeOS. + +A6) How can I build bash with gcc? + +Bash configures to use gcc by default if it is available. Read the +file INSTALL in the distribution for more information. + +A7) How can I make bash my login shell? + +Some machines let you use `chsh' to change your login shell. Other +systems use `passwd -s' or `passwd -e'. If one of these works for +you, that's all you need. Note that many systems require the full +pathname to a shell to appear in /etc/shells before you can make it +your login shell. For this, you may need the assistance of your +friendly local system administrator. + +If you cannot do this, you can still use bash as your login shell, but +you need to perform some tricks. The basic idea is to add a command +to your login shell's startup file to replace your login shell with +bash. + +For example, if your login shell is csh or tcsh, and you have installed +bash in /usr/gnu/bin/bash, add the following line to ~/.login: + + if ( -f /usr/gnu/bin/bash ) exec /usr/gnu/bin/bash --login + +(the `--login' tells bash that it is a login shell). + +It's not a good idea to put this command into ~/.cshrc, because every +csh you run without the `-f' option, even ones started to run csh scripts, +reads that file. If you must put the command in ~/.cshrc, use something +like + + if ( $?prompt ) exec /usr/gnu/bin/bash --login + +to ensure that bash is exec'd only when the csh is interactive. + +If your login shell is sh or ksh, you have to do two things. + +First, create an empty file in your home directory named `.bash_profile'. +The existence of this file will prevent the exec'd bash from trying to +read ~/.profile, and re-execing itself over and over again. ~/.bash_profile +is the first file bash tries to read initialization commands from when +it is invoked as a login shell. + +Next, add a line similar to the above to ~/.profile: + + [ -f /usr/gnu/bin/bash ] && [ -x /usr/gnu/bin/bash ] && \ + exec /usr/gnu/bin/bash --login + +This will cause login shells to replace themselves with bash running as +a login shell. Once you have this working, you can copy your initialization +code from ~/.profile to ~/.bash_profile. + +I have received word that the recipe supplied above is insufficient for +machines running CDE. CDE has a maze of twisty little startup files, all +slightly different. + +If you cannot change your login shell in the password file to bash, you +will have to (apparently) live with CDE using the shell in the password +file to run its startup scripts. If you have changed your shell to bash, +there is code in the CDE startup files (on Solaris, at least) that attempts +to do the right thing. It is, however, often broken, and may require that +you use the $BASH_ENV trick described below. + +`dtterm' claims to use $SHELL as the default program to start, so if you +can change $SHELL in the CDE startup files, you should be able to use bash +in your terminal windows. + +Setting DTSOURCEPROFILE in ~/.dtprofile will cause the `Xsession' program +to read your login shell's startup files. You may be able to use bash for +the rest of the CDE programs by setting SHELL to bash in ~/.dtprofile as +well, but I have not tried this. + +You can use the above `exec' recipe to start bash when not logging in with +CDE by testing the value of the DT variable: + + if [ -n "$DT" ]; then + [ -f /usr/gnu/bin/bash ] && exec /usr/gnu/bin/bash --login + fi + +If CDE starts its shells non-interactively during login, the login shell +startup files (~/.profile, ~/.bash_profile) will not be sourced at login. +To get around this problem, append a line similar to the following to your +~/.dtprofile: + + BASH_ENV=${HOME}/.bash_profile ; export BASH_ENV + +and add the following line to the beginning of ~/.bash_profile: + + unset BASH_ENV + +A8) I just changed my login shell to bash, and now I can't FTP into my + machine. Why not? + +You must add the full pathname to bash to the file /etc/shells. As +noted in the answer to the previous question, many systems require +this before you can make bash your login shell. + +Most versions of ftpd use this file to prohibit `special' users +such as `uucp' and `news' from using FTP. + +A9) What's the `POSIX Shell and Utilities standard'? + +POSIX is a name originally coined by Richard Stallman for a +family of open system standards based on UNIX. There are a +number of aspects of UNIX under consideration for +standardization, from the basic system services at the system +call and C library level to applications and tools to system +administration and management. Each area of standardization is +assigned to a working group in the 1003 series. + +The POSIX Shell and Utilities standard was originally developed by +IEEE Working Group 1003.2 (POSIX.2). Today it has been merged with +the original 1003.1 Working Group and is maintained by the Austin +Group (a joint working group of the IEEE, The Open Group and +ISO/IEC SC22/WG15). Today the Shell and Utilities are a volume +within the set of documents that make up IEEE Std 1003.1-2001, and +thus now the former POSIX.2 (from 1992) is now part of the current +POSIX.1 standard (POSIX 1003.1-2001). + +The Shell and Utilities volume concentrates on the command +interpreter interface and utility programs commonly executed from +the command line or by other programs. The standard is freely +available on the web at http://www.UNIX-systems.org/version3/ . +Work continues at the Austin Group on maintenance issues; see +http://www.opengroup.org/austin/ to join the discussions. + +Bash is concerned with the aspects of the shell's behavior defined +by the POSIX Shell and Utilities volume. The shell command +language has of course been standardized, including the basic flow +control and program execution constructs, I/O redirection and +pipelining, argument handling, variable expansion, and quoting. + +The `special' builtins, which must be implemented as part of the +shell to provide the desired functionality, are specified as +being part of the shell; examples of these are `eval' and +`export'. Other utilities appear in the sections of POSIX not +devoted to the shell which are commonly (and in some cases must +be) implemented as builtin commands, such as `read' and `test'. +POSIX also specifies aspects of the shell's interactive +behavior as part of the UPE, including job control and command +line editing. Only vi-style line editing commands have been +standardized; emacs editing commands were left out due to +objections. + +The latest version of the POSIX Shell and Utilities standard is +available (now updated to the 2003 Edition incorporating the +Technical Corrigendum 1), as part of the Single UNIX Specification +Version 3 at + +http://www.UNIX-systems.org/version3/ + +A10) What is the bash `posix mode'? + +Although bash is an implementation of the POSIX shell +specification, there are areas where the bash default behavior +differs from that spec. The bash `posix mode' changes the bash +behavior in these areas so that it obeys the spec more closely. + +Posix mode is entered by starting bash with the --posix or +'-o posix' option or executing `set -o posix' after bash is running. + +The specific aspects of bash which change when posix mode is +active are listed in the file POSIX in the bash distribution. +They are also listed in a section in the Bash Reference Manual +(from which that file is generated). + +Section B: The latest version + +B1) What's new in version 2.05b? + +The raison d'etre for bash-2.05b is to make a second intermediate +release containing the first of the new features to be available +in bash-3.0 and get feedback on those features before proceeding. +The major new feature is multibyte character support in both Bash +and Readline. + +Bash-2.05b contains the following new features (see the manual page for +complete descriptions and the CHANGES and NEWS files in the bash-2.05b +distribution): + +o support for multibyte characters has been added to both bash and readline + +o the DEBUG trap is now run *before* simple commands, ((...)) commands, + [[...]] conditional commands, and for ((...)) loops + +o the shell now performs arithmetic in the largest integer size the machine + supports (intmax_t) + +o there is a new \D{...} prompt expansion; passes the `...' to strftime(3) + and inserts the result into the expanded prompt + +o there is a new `here-string' redirection operator: <<< word + +o when displaying variables, function attributes and definitions are shown + separately, allowing them to be re-used as input (attempting to re-use + the old output would result in syntax errors). + +o `read' has a new `-u fd' option to read from a specified file descriptor + +o the bash debugger in examples/bashdb has been modified to work with the + new DEBUG trap semantics, the command set has been made more gdb-like, + and the changes to $LINENO make debugging functions work better + +o the expansion of $LINENO inside a shell function is only relative to the + function start if the shell is interactive -- if the shell is running a + script, $LINENO expands to the line number in the script.

+ +D1) Why does bash run a different version of `command' than + `which command' says it will? + +On many systems, `which' is actually a csh script that assumes +you're running csh. In tcsh, `which' and its cousin `where' +are builtins. On other Unix systems, `which' is a perl script +that uses the PATH environment variable. + +The csh script version reads the csh startup files from your +home directory and uses those to determine which `command' will +be invoked. Since bash doesn't use any of those startup files, +there's a good chance that your bash environment differs from +your csh environment. The bash `type' builtin does everything +`which' does, and will report correct results for the running +shell. If you're really wedded to the name `which', try adding +the following function definition to your .bashrc: + + which() + { + builtin type "$@" + } + +If you're moving from tcsh and would like to bring `where' along +as well, use this function: + + where() + { + builtin type -a "$@" + } + +D2) Why doesn't bash treat brace expansions exactly like csh? + +The only difference between bash and csh brace expansion is that +bash requires a brace expression to contain at least one unquoted +comma if it is to be expanded. Any brace-surrounded word not +containing an unquoted comma is left unchanged by the brace +expansion code. This affords the greatest degree of sh +compatibility. + +Bash, ksh, zsh, and pd-ksh all implement brace expansion this way. + +D3) Why doesn't bash have csh variable modifiers? + +Posix has specified a more powerful, albeit somewhat more cryptic, +mechanism cribbed from ksh, and bash implements it. + +${parameter%word} + Remove smallest suffix pattern. The WORD is expanded to produce + a pattern.

The WORD is expanded to produce + a pattern.

We have provided +a shell script which does most of the work of conversion for you; +this script can be found in ./examples/misc/aliasconv.sh. Here is +how you use it: + +Start csh in the normal way for you. (e.g., `csh') + +Pipe the output of `alias' through `aliasconv.sh', saving the +results into `bash_aliases': + + alias | bash aliasconv.sh >bash_aliases + +Edit `bash_aliases', carefully reading through any created +functions. You will need to change the names of some csh specific +variables to the bash equivalents. The script converts $cwd to +$PWD, $term to $TERM, $home to $HOME, $user to $USER, and $prompt +to $PS1. You may also have to add quotes to avoid unwanted +expansion. + +For example, the csh alias: + + alias cd 'cd \!*; echo $cwd' + +is converted to the bash function: + + cd () { command cd "$@"; echo $PWD ; } + +The only thing that needs to be done is to quote $PWD: + + cd () { command cd "$@"; echo "$PWD" ; } + +Merge the edited file into your ~/.bashrc. + +There is an additional, more ambitious, script in +examples/misc/cshtobash that attempts to convert your entire csh +environment to its bash equivalent. This script can be run as +simply `cshtobash' to convert your normal interactive +environment, or as `cshtobash ~/.login' to convert your login +environment. + +D5) How can I pipe standard output and standard error from one command to + another, like csh does with `|&'? + +Use + command 2>&1 | command2 + +The key is to remember that piping is performed before redirection, so +file descriptor 1 points to the pipe when it is duplicated onto file +descriptor 2. + +D6) Now that I've converted from ksh to bash, are there equivalents to + ksh features like autoloaded functions and the `whence' command? + +There are features in ksh-88 and ksh-93 that do not have direct bash +equivalents. Most, however, can be emulated with very little trouble. + +ksh-88 feature Bash equivalent +-------------- --------------- +compiled-in aliases set up aliases in .bashrc; some ksh aliases are + bash builtins (hash, history, type) +coprocesses named pipe pairs (one for read, one for write) +typeset +f declare -F +cd, print, whence function substitutes in examples/functions/kshenv +autoloaded functions examples/functions/autoload is the same as typeset -fu +read var?prompt read -p prompt var + +ksh-93 feature Bash equivalent +-------------- --------------- +sleep, getconf Bash has loadable versions in examples/loadables +${.sh.version} $BASH_VERSION +print -f printf +hist alias hist=fc +$HISTEDIT $FCEDIT + +Section E: How can I get bash to do certain things, and why does bash do + things the way it does? + +E1) Why is the bash builtin `test' slightly different from /bin/test? + +The specific example used here is [ ! x -o x ], which is false. + +Bash's builtin `test' implements the Posix.2 spec, which can be +summarized as follows (the wording is due to David Korn): + +Here is the set of rules for processing test arguments. + + 0 Args: False + 1 Arg: True iff argument is not null. + 2 Args: If first arg is !, True iff second argument is null. + If first argument is unary, then true if unary test is true + Otherwise error. + 3 Args: If second argument is a binary operator, do binary test of $1 $3 + If first argument is !, negate two argument test of $2 $3 + If first argument is `(' and third argument is `)', do the + one-argument test of the second argument. + Otherwise error. + 4 Args: If first argument is !, negate three argument test of $2 $3 $4. + Otherwise unspecified + 5 or more Args: unspecified. (Historical shells would use their + current algorithm). + +The operators -a and -o are considered binary operators for the purpose +of the 3 Arg case. + +As you can see, the test becomes (not (x or x)), which is false. + +E2) Why does bash sometimes say `Broken pipe'? + +If a sequence of commands appears in a pipeline, and one of the +reading commands finishes before the writer has finished, the +writer receives a SIGPIPE signal. Many other shells special-case +SIGPIPE as an exit status in the pipeline and do not report it. +For example, in: + + ps -aux | head + +`head' can finish before `ps' writes all of its output, and ps +will try to write on a pipe without a reader. In that case, bash +will print `Broken pipe' to stderr when ps is killed by a +SIGPIPE. + +You can build a version of bash that will not report SIGPIPE errors +by uncommenting the definition of DONT_REPORT_SIGPIPE in the file +config-top.h. + +E3) When I have terminal escape sequences in my prompt, why does bash + wrap lines at the wrong column? + +Readline, the line editing library that bash uses, does not know +that the terminal escape sequences do not take up space on the +screen. The redisplay code assumes, unless told otherwise, that +each character in the prompt is a `printable' character that +takes up one character position on the screen. + +You can use the bash prompt expansion facility (see the PROMPTING +section in the manual page) to tell readline that sequences of +characters in the prompt strings take up no screen space. + +Use the \[ escape to begin a sequence of non-printing characters, +and the \] escape to signal the end of such a sequence. + +E4) If I pipe the output of a command into `read variable', why doesn't + the output show up in $variable when the read command finishes? + +This has to do with the parent-child relationship between Unix +processes. It affects all commands run in pipelines, not just +simple calls to `read'. For example, piping a command's output +into a `while' loop that repeatedly calls `read' will result in +the same behavior. + +Each element of a pipeline runs in a separate process, a child of +the shell running the pipeline. A subprocess cannot affect its +parent's environment. When the `read' command sets the variable +to the input, that variable is set only in the subshell, not the +parent shell. When the subshell exits, the value of the variable +is lost. + +Many pipelines that end with `read variable' can be converted +into command substitutions, which will capture the output of +a specified command. The output can then be assigned to a +variable: + + grep ^gnu /usr/lib/news/active | wc -l | read ngroup + +can be converted into + + ngroup=$(grep ^gnu /usr/lib/news/active | wc -l) + +This does not, unfortunately, work to split the text among +multiple variables, as read does when given multiple variable +arguments. If you need to do this, you can either use the +command substitution above to read the output into a variable +and chop up the variable using the bash pattern removal +expansion operators or use some variant of the following +approach. + +Say /usr/local/bin/ipaddr is the following shell script: + +#! /bin/sh +host `hostname` | awk '/address/ {print $NF}' + +Instead of using + + /usr/local/bin/ipaddr | read A B C D + +to break the local machine's IP address into separate octets, use + + OIFS="$IFS" + IFS=. + set -- $(/usr/local/bin/ipaddr) + IFS="$OIFS" + A="$1" B="$2" C="$3" D="$4" + +Beware, however, that this will change the shell's positional +parameters. If you need them, you should save them before doing +this. + +This is the general approach -- in most cases you will not need to +set $IFS to a different value. + +Some other user-supplied alternatives include: + +read A B C D << HERE + $(IFS=.; echo $(/usr/local/bin/ipaddr)) +HERE + +and, where process substitution is available, + +read A B C D < <(IFS=.; echo $(/usr/local/bin/ipaddr)) + +E5) I have a bunch of shell scripts that use backslash-escaped characters + in arguments to `echo'. Bash doesn't interpret these characters. Why + not, and how can I make it understand them? + +This is the behavior of echo on most Unix System V machines. + +The bash builtin `echo' is modeled after the 9th Edition +Research Unix version of `echo'. It does not interpret +backslash-escaped characters in its argument strings by default; +it requires the use of the -e option to enable the +interpretation. The System V echo provides no way to disable the +special characters; the bash echo has a -E option to disable +them. + +There is a configuration option that will make bash behave like +the System V echo and interpret things like `\t' by default. Run +configure with the --enable-xpg-echo-default option to turn this +on. Be aware that this will cause some of the tests run when you +type `make tests' to fail. + +There is a shell option, `xpg_echo', settable with `shopt', that will +change the behavior of echo at runtime. Enabling this option turns +on expansion of backslash-escape sequences. + +E6) Why doesn't a while or for loop get suspended when I type ^Z? + +This is a consequence of how job control works on Unix. The only +thing that can be suspended is the process group. This is a single +command or pipeline of commands that the shell forks and executes. + +When you run a while or for loop, the only thing that the shell forks +and executes are any commands in the while loop test and commands in +the loop bodies. These, therefore, are the only things that can be +suspended when you type ^Z. + +If you want to be able to stop the entire loop, you need to put it +within parentheses, which will force the loop into a subshell that +may be stopped (and subsequently restarted) as a single unit. + +E7) What about empty for loops in Makefiles? + +It's fairly common to see constructs like this in automatically-generated +Makefiles: + +SUBDIRS = @SUBDIRS@ + + ... + +subdirs-clean: + for d in ${SUBDIRS}; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +When SUBDIRS is empty, this results in a command like this being passed to +bash: + + for d in ; do + ( cd $d && ${MAKE} ${MFLAGS} clean ) + done + +In versions of bash before bash-2.05a, this was a syntax error. If the +reserved word `in' was present, a word must follow it before the semicolon +or newline. The language in the manual page referring to the list of words +being empty referred to the list after it is expanded. These versions of +bash required that there be at least one word following the `in' when the +construct was parsed. + +The idiomatic Makefile solution is something like: + +SUBDIRS = @SUBDIRS@ + +subdirs-clean: + subdirs=$SUBDIRS ; for d in $$subdirs; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +The latest drafts of the updated POSIX standard have changed this: the +word list is no longer required. Bash versions 2.05a and later accept +the new syntax. + +E8) Why does the arithmetic evaluation code complain about `08'? + +The bash arithmetic evaluation code (used for `let', $(()), (()), and in +other places), interprets a leading `0' in numeric constants as denoting +an octal number, and a leading `0x' as denoting hexadecimal. This is +in accordance with the POSIX.2 spec, section 2.9.2.1, which states that +arithmetic constants should be handled as signed long integers as defined +by the ANSI/ISO C standard. + +The POSIX.2 interpretation committee has confirmed this: + +http://www.pasc.org/interps/unofficial/db/p1003.2/pasc-1003.2-173.html + +E9) Why does the pattern matching expression [A-Z]* match files beginning + with every letter except `z'? + +Bash-2.03, Bash-2.05 and later versions honor the current locale setting +when processing ranges within pattern matching bracket expressions ([A-Z]). +This is what POSIX.2 and SUSv3/XPG6 specify. + +The behavior of the matcher in bash-2.05 and later versions depends on the +current LC_COLLATE setting. Setting this variable to `C' or `POSIX' will +result in the traditional behavior ([A-Z] matches all uppercase ASCII +characters). Many other locales, including the en_US locale (the default +on many US versions of Linux) collate the upper and lower case letters like +this: + + AaBb...Zz + +which means that [A-Z] matches every letter except `z'. Others collate like + + aAbBcC...zZ + +which means that [A-Z] matches every letter except `a'. + +The portable way to specify upper case letters is [:upper:] instead of +A-Z; lower case may be specified as [:lower:] instead of a-z. + +Look at the manual pages for setlocale(3), strcoll(3), and, if it is +present, locale(1). If you have locale(1), you can use it to find +your current locale information even if you do not have any of the +LC_ variables set. + +My advice is to put + + export LC_COLLATE=C + +into /etc/profile and inspect any shell scripts run from cron for +constructs like [A-Z]. This will prevent things like + + rm [A-Z]* + +from removing every file in the current directory except those beginning +with `z' and still allow individual users to change the collation order. +Users may put the above command into their own profiles as well, of course. + +E10) Why does `cd //' leave $PWD as `//'? + +POSIX.2, in its description of `cd', says that *three* or more leading +slashes may be replaced with a single slash when canonicalizing the +current working directory. + +This is, I presume, for historical compatibility. Certain versions of +Unix, and early network file systems, used paths of the form +//hostname/path to access `path' on server `hostname'. + +E11) If I resize my xterm while another program is running, why doesn't bash + notice the change? + +This is another issue that deals with job control. + +The kernel maintains a notion of a current terminal process group. Members +of this process group (processes whose process group ID is equal to the +current terminal process group ID) receive terminal-generated signals like +SIGWINCH. (For more details, see the JOB CONTROL section of the bash +man page.) + +If a terminal is resized, the kernel sends SIGWINCH to each member of +the terminal's current process group (the `foreground' process group). + +When bash is running with job control enabled, each pipeline (which may be +a single command) is run in its own process group, different from bash's +process group. This foreground process group receives the SIGWINCH; bash +does not. Bash has no way of knowing that the terminal has been resized. + +There is a `checkwinsize' option, settable with the `shopt' builtin, that +will cause bash to check the window size and adjust its idea of the +terminal's dimensions each time a process stops or exits and returns control +of the terminal to bash. Enable it with `shopt -s checkwinsize'. + +E12) Why don't negative offsets in substring expansion work like I expect? + +When substring expansion of the form ${param:offset[:length} is used, +an `offset' that evaluates to a number less than zero counts back from +the end of the expanded value of $param. + +When a negative `offset' begins with a minus sign, however, unexpected things +can happen. Consider + + a=12345678 + echo ${a:-4} + +intending to print the last four characters of $a. The problem is that +${param:-word} already has a well-defined meaning: expand to word if the +expanded value of param is unset or null, and $param otherwise. + +To use negative offsets that begin with a minus sign, separate the +minus sign and the colon with a space. + +Section F: Things to watch out for on certain Unix versions + +F1) Why can't I use command line editing in my `cmdtool'? + +The problem is `cmdtool' and bash fighting over the input. When +scrolling is enabled in a cmdtool window, cmdtool puts the tty in +`raw mode' to permit command-line editing using the mouse for +applications that cannot do it themselves. As a result, bash and +cmdtool each try to read keyboard input immediately, with neither +getting enough of it to be useful. + +This mode also causes cmdtool to not implement many of the +terminal functions and control sequences appearing in the +`sun-cmd' termcap entry. For a more complete explanation, see +that file examples/suncmd.termcap in the bash distribution. + +`xterm' is a better choice, and gets along with bash much more +smoothly. + +If you must use cmdtool, you can use the termcap description in +examples/suncmd.termcap. Set the TERMCAP variable to the terminal +description contained in that file, i.e. + +TERMCAP='Mu|sun-cmd:am:bs:km:pt:li#34:co#80:cl=^L:ce=\E[K:cd=\E[J:rs=\E[s:' + +Then export TERMCAP and start a new cmdtool window from that shell. +The bash command-line editing should behave better in the new +cmdtool. If this works, you can put the assignment to TERMCAP +in your bashrc file. + +F2) I built bash on Solaris 2. Why do globbing expansions and filename + completion chop off the first few characters of each filename? + +This is the consequence of building bash on SunOS 5 and linking +with the libraries in /usr/ucblib, but using the definitions +and structures from files in /usr/include. + +The actual conflict is between the dirent structure in +/usr/include/dirent.h and the struct returned by the version of +`readdir' in libucb.a (a 4.3-BSD style `struct direct'). + +Make sure you've got /usr/ccs/bin ahead of /usr/ucb in your $PATH +when configuring and building bash. This will ensure that you +use /usr/ccs/bin/cc or acc instead of /usr/ucb/cc and that you +link with libc before libucb. + +If you have installed the Sun C compiler, you may also need to +put /usr/ccs/bin and /opt/SUNWspro/bin into your $PATH before +/usr/ucb. + +F3) Why does bash dump core after I interrupt username completion or + `~user' tilde expansion on a machine running NIS? + +This is a famous and long-standing bug in the SunOS YP (sorry, NIS) +client library, which is part of libc. + +The YP library code keeps static state -- a pointer into the data +returned from the server. When YP initializes itself (setpwent), +it looks at this pointer and calls free on it if it's non-null. +So far, so good. + +If one of the YP functions is interrupted during getpwent (the +exact function is interpretwithsave()), and returns NULL, the +pointer is freed without being reset to NULL, and the function +returns. The next time getpwent is called, it sees that this +pointer is non-null, calls free, and the bash free() blows up +because it's being asked to free freed memory. + +The traditional Unix mallocs allow memory to be freed multiple +times; that's probably why this has never been fixed. You can +run configure with the `--without-gnu-malloc' option to use +the C library malloc and avoid the problem. + +F4) I'm running SVR4.2. Why is the line erased every time I type `@'? + +The `@' character is the default `line kill' character in most +versions of System V, including SVR4.2. You can change this +character to whatever you want using `stty'. For example, to +change the line kill character to control-u, type + + stty kill ^U + +where the `^' and `U' can be two separate characters. + +F5) Why does bash report syntax errors when my C News scripts use a + redirection before a subshell command? + +The actual command in question is something like + + < file ( command ) + +According to the grammar given in the POSIX.2 standard, this construct +is, in fact, a syntax error. Redirections may only precede `simple +commands'. A subshell construct such as the above is one of the shell's +`compound commands'. A redirection may only follow a compound command. + +This affects the mechanical transformation of commands that use `cat' +to pipe a file into a command (a favorite Useless-Use-Of-Cat topic on +comp.unix.shell). While most commands of the form + + cat file | command + +can be converted to `< file command', shell control structures such as +loops and subshells require `command < file'. + +The file CWRU/sh-redir-hack in the bash-2.05a distribution is an +(unofficial) patch to parse.y that will modify the grammar to +support this construct. It will not apply with `patch'; you must +modify parse.y by hand. Note that if you apply this, you must +recompile with -DREDIRECTION_HACK. This introduces a large +number of reduce/reduce conflicts into the shell grammar. + +F6) Why can't I use vi-mode editing on Red Hat Linux 6.1? + +The short answer is that Red Hat screwed up. + +The long answer is that they shipped an /etc/inputrc that only works +for emacs mode editing, and then screwed all the vi users by setting +INPUTRC to /etc/inputrc in /etc/profile. + +The short fix is to do one of the following: remove or rename +/etc/inputrc, set INPUTRC=~/.inputrc in ~/.bashrc (or .bash_profile, +but make sure you export it if you do), remove the assignment to +INPUTRC from /etc/profile, add + + set keymap emacs + +to the beginning of /etc/inputrc, or bracket the key bindings in +/etc/inputrc with these lines + + $if mode=emacs + [...] + $endif + +F7) Why do bash-2.05a and bash-2.05b fail to compile `printf.def' on + HP/UX 11.x? + +HP/UX's support for long double is imperfect at best. + +GCC will support it without problems, but the HP C library functions +like strtold(3) and printf(3) don't actually work with long doubles. +HP implemented a `long_double' type as a 4-element array of 32-bit +ints, and that is what the library functions use. The ANSI C +`long double' type is a 128-bit floating point scalar. + +The easiest fix, until HP fixes things up, is to edit the generated +config.h and #undef the HAVE_LONG_DOUBLE line. After doing that, +the compilation should complete successfully. + +Section G: How can I get bash to do certain common things? + +G1) How can I get bash to read and display eight-bit characters? + +This is a process requiring several steps. + +First, you must ensure that the `physical' data path is a full eight +bits. For xterms, for example, the `vt100' resources `eightBitInput' +and `eightBitOutput' should be set to `true'. + +Once you have set up an eight-bit path, you must tell the kernel and +tty driver to leave the eighth bit of characters alone when processing +keyboard input. Use `stty' to do this: + + stty cs8 -istrip -parenb + +For old BSD-style systems, you can use + + stty pass8 + +You may also need + + stty even odd + +Finally, you need to tell readline that you will be inputting and +displaying eight-bit characters. You use readline variables to do +this. These variables can be set in your .inputrc or using the bash +`bind' builtin. Here's an example using `bind': + + bash$ bind 'set convert-meta off' + bash$ bind 'set meta-flag on' + bash$ bind 'set output-meta on' + +The `set' commands between the single quotes may also be placed +in ~/.inputrc. + +G2) How do I write a function `x' to replace builtin command `x', but + still invoke the command from within the function? + +This is why the `command' and `builtin' builtins exist. The +`command' builtin executes the command supplied as its first +argument, skipping over any function defined with that name. The +`builtin' builtin executes the builtin command given as its first +argument directly. + +For example, to write a function to replace `cd' that writes the +hostname and current directory to an xterm title bar, use +something like the following: + + cd() + { + builtin cd "$@" && xtitle "$HOST: $PWD" + } + +This could also be written using `command' instead of `builtin'; +the version above is marginally more efficient. + +G3) How can I find the value of a shell variable whose name is the value + of another shell variable? + +Versions of Bash newer than Bash-2.0 support this directly. You can use + + ${!var} + +For example, the following sequence of commands will echo `z': + + var1=var2 + var2=z + echo ${!var1} + +For sh compatibility, use the `eval' builtin. The important +thing to remember is that `eval' expands the arguments you give +it again, so you need to quote the parts of the arguments that +you want `eval' to act on. + +For example, this expression prints the value of the last positional +parameter: + + eval echo \"\$\{$#\}\" + +The expansion of the quoted portions of this expression will be +deferred until `eval' runs, while the `$#' will be expanded +before `eval' is executed. In versions of bash later than bash-2.0, + + echo ${!#} + +does the same thing. + +This is not the same thing as ksh93 `nameref' variables, though the syntax +is similar. I may add namerefs in a future bash version. + +G4) How can I make the bash `time' reserved word print timing output that + looks like the output from my system's /usr/bin/time? + +The bash command timing code looks for a variable `TIMEFORMAT' and +uses its value as a format string to decide how to display the +timing statistics. + +The value of TIMEFORMAT is a string with `%' escapes expanded in a +fashion similar in spirit to printf(3). The manual page explains +the meanings of the escape sequences in the format string. + +If TIMEFORMAT is not set, bash acts as if the following assignment had +been performed: + + TIMEFORMAT=$'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS' + +The POSIX.2 default time format (used by `time -p command') is + + TIMEFORMAT=$'real %2R\nuser %2U\nsys %2S' + +The BSD /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\t%1R real\t%1U user\t%1S sys' + +The System V /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\nreal\t%1R\nuser\t%1U\nsys\t%1S' + +The ksh format can be emulated with: + + TIMEFORMAT=$'\nreal\t%2lR\nuser\t%2lU\nsys\t%2lS' + +G5) How do I get the current directory into my prompt? + +Bash provides a number of backslash-escape sequences which are expanded +when the prompt string (PS1 or PS2) is displayed. The full list is in +the manual page. + +The \w expansion gives the full pathname of the current directory, with +a tilde (`~') substituted for the current value of $HOME. The \W +expansion gives the basename of the current directory. To put the full +pathname of the current directory into the path without any tilde +subsitution, use $PWD. Here are some examples: + + PS1='\w$ ' # current directory with tilde + PS1='\W$ ' # basename of current directory + PS1='$PWD$ ' # full pathname of current directory + +The single quotes are important in the final example to prevent $PWD from +being expanded when the assignment to PS1 is performed. + +G6) How can I rename "*.foo" to "*.bar"? + +Use the pattern removal functionality described in D3. The following `for' +loop will do the trick: + + for f in *.foo; do + mv $f ${f%foo}bar + done + +G7) How can I translate a filename from uppercase to lowercase? + +The script examples/functions/lowercase, originally written by John DuBois, +will do the trick. The converse is left as an exercise. + +G8) How can I write a filename expansion (globbing) pattern that will match + all files in the current directory except "." and ".."? + +You must have set the `extglob' shell option using `shopt -s extglob' to use +this: + + echo .!(.|) * + +A solution that works without extended globbing is given in the Unix Shell +FAQ, posted periodically to comp.unix.shell. + +Section H: Where do I go from here? + +H1) How do I report bugs in bash, and where should I look for fixes and + advice? + +Use the `bashbug' script to report bugs. It is built and +installed at the same time as bash. It provides a standard +template for reporting a problem and automatically includes +information about your configuration and build environment. + +`bashbug' sends its reports to bug-bash@gnu.org, which +is a large mailing list gatewayed to the usenet newsgroup gnu.bash.bug. + +Bug fixes, answers to questions, and announcements of new releases +are all posted to gnu.bash.bug. Discussions concerning bash features +and problems also take place there. + +To reach the bash maintainers directly, send mail to +bash-maintainers@gnu.org. + +H2) What kind of bash documentation is there? + +First, look in the doc directory in the bash distribution. It should +contain at least the following files: + +bash.1 an extensive, thorough Unix-style manual page +builtins.1 a manual page covering just bash builtin commands +bashref.texi a reference manual in GNU tex`info format +bashref.info an info version of the reference manual +FAQ this file +article.ms text of an article written for The Linux Journal +readline.3 a man page describing readline + +Postscript, HTML, and ASCII files created from the above source are +available in the documentation distribution. + +There is additional documentation available for anonymous FTP from host +ftp.cwru.edu in the `pub/bash' directory. + +Cameron Newham and Bill Rosenblatt have written a book on bash, published +by O'Reilly and Associates. The book is based on Bill Rosenblatt's Korn +Shell book. The title is ``Learning the Bash Shell'', and the ISBN number +is 1-56592-147-X. Look for it in fine bookstores near you. This book +covers bash-1.14, but has an appendix describing some of the new features +in bash-2.0. + +A second edition of this book is available, published in January, 1998. +The ISBN number is 1-56592-347-2. Look for it in the same fine bookstores +or on the web. + +The GNU Bash Reference Manual has been published as a printed book by +Network Theory Ltd (Paperback, ISBN: 0-9541617-7-7, Feb 2003). It covers +bash-2.0 and is available from most online bookstores (see +http://www.network-theory.co.uk/bash/manual/ for details). The publisher +will donate $1 to the Free Software Foundation for each copy sold. + +H3) What's coming in future versions? + +These are features I hope to include in a future version of bash. + +a better bash debugger (a minimally-tested version is included with bash-2.05b) +associative arrays +co-processes, but with a new-style syntax that looks like function declaration + +H4) What's on the bash `wish list' for future versions? + +These are features that may or may not appear in a future version of bash. + +breaking some of the shell functionality into embeddable libraries +a module system like zsh's, using dynamic loading like builtins +better internationalization using GNU `gettext' +date-stamped command history +a bash programmer's guide with a chapter on creating loadable builtins +a better loadable interface to perl with access to the shell builtins and + variables (contributions gratefully accepted) +ksh93-like `nameref' variables +ksh93-like `+=' variable assignment operator +ksh93-like `xx.yy' variables (including some of the .sh.* variables) and + associated disipline functions +Some of the new ksh93 pattern matching operators, like backreferencing + +H5) When will the next release appear? + +The next version will appear sometime in 2003.

It is an implementation of +the Posix 1003.2 shell standard, and resembles the Korn and System V +shells. + +Bash contains a number of enhancements over those shells, both +for interactive use and shell programming. Features geared +toward interactive use include command line editing, command +history, job control, aliases, and prompt expansion. Programming +features include additional variable expansions, shell +arithmetic, and a number of variables and options to control +shell behavior. + +Bash was originally written by Brian Fox of the Free Software +Foundation. The current developer and maintainer is Chet Ramey +of Case Western Reserve University. + +A2) What's the latest version? + +The latest version is 3.0, first made available on 27 July, 2004. + +A3) Where can I get it? + +Bash is the GNU project's shell, and so is available from the +master GNU archive site, ftp.gnu.org, and its mirrors. The +latest version is also available for FTP from ftp.cwru.edu. +The following URLs tell how to get version 3.0: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-3.0.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-3.0.tar.gz + +Formatted versions of the documentation are available with the URLs: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-doc-3.0.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-doc-3.0.tar.gz + +Any patches for the current version are available with the URL: + +ftp://ftp.cwru.edu/pub/bash/bash-3.0-patches/ + +A4) On what machines will bash run? + +Bash has been ported to nearly every version of Unix. All you +should have to do to build it on a machine for which a port +exists is to type `configure' and then `make'. The build process +will attempt to discover the version of Unix you have and tailor +itself accordingly, using a script created by GNU autoconf. + +More information appears in the file `INSTALL' in the distribution. + +The Bash web page (http://cnswww.cns.cwru.edu/~chet/bash/bashtop.html) +explains how to obtain binary versions of bash for most of the major +commercial Unix systems. + +A5) Will bash run on operating systems other than Unix? + +Configuration specifics for Unix-like systems such as QNX and +LynxOS are included in the distribution. Bash-2.05 and later +versions should compile and run on Minix 2.0 (patches were +contributed), but I don't believe anyone has built bash-2.x on +earlier Minix versions yet. + +Bash has been ported to versions of Windows implementing the Win32 +programming interface. This includes Windows 95 and Windows NT. +The port was done by Cygnus Solutions (now part of Red Hat) as part +of their CYGWIN project. For more information about the project, see +http://www.cygwin.com/. + +Cygnus originally ported bash-1.14.7, and that port was part of their +early GNU-Win32 (the original name) releases. Cygnus has also done a +port of bash-2.05b to the CYGWIN environment, and it is available as +part of their current release. Bash-3.0 is currently being tested and +should be available soon. + +Bash-2.05b and later versions should require no local Cygnus changes to +build and run under CYGWIN. + +DJ Delorie has a port of bash-2.x which runs under MS-DOS, as part +of the DJGPP project. For more information on the project, see + +http://www.delorie.com/djgpp/ + +I have been told that the original DJGPP port was done by Daisuke Aoyama. + +Mark Elbrecht has sent me notice that bash-2.04 +is available for DJGPP V2. The files are available as: + +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204b.zip binary +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204d.zip documentation +ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/bsh204s.zip source + +Mark began to work with bash-2.05, but I don't know the current status. + +Bash-3.0 compiles and runs with no modifications under Microsoft's Services +for Unix (SFU), once known as Interix. + +A6) How can I build bash with gcc? + +Bash configures to use gcc by default if it is available. Read the +file INSTALL in the distribution for more information. + +A7) How can I make bash my login shell? + +Some machines let you use `chsh' to change your login shell. Other +systems use `passwd -s' or `passwd -e'. If one of these works for +you, that's all you need. Note that many systems require the full +pathname to a shell to appear in /etc/shells before you can make it +your login shell. For this, you may need the assistance of your +friendly local system administrator. + +If you cannot do this, you can still use bash as your login shell, but +you need to perform some tricks. The basic idea is to add a command +to your login shell's startup file to replace your login shell with +bash. + +For example, if your login shell is csh or tcsh, and you have installed +bash in /usr/gnu/bin/bash, add the following line to ~/.login: + + if ( -f /usr/gnu/bin/bash ) exec /usr/gnu/bin/bash --login + +(the `--login' tells bash that it is a login shell). + +It's not a good idea to put this command into ~/.cshrc, because every +csh you run without the `-f' option, even ones started to run csh scripts, +reads that file. If you must put the command in ~/.cshrc, use something +like + + if ( $?prompt ) exec /usr/gnu/bin/bash --login + +to ensure that bash is exec'd only when the csh is interactive. + +If your login shell is sh or ksh, you have to do two things. + +First, create an empty file in your home directory named `.bash_profile'. +The existence of this file will prevent the exec'd bash from trying to +read ~/.profile, and re-execing itself over and over again. ~/.bash_profile +is the first file bash tries to read initialization commands from when +it is invoked as a login shell. + +Next, add a line similar to the above to ~/.profile: + + [ -f /usr/gnu/bin/bash ] && [ -x /usr/gnu/bin/bash ] && \ + exec /usr/gnu/bin/bash --login + +This will cause login shells to replace themselves with bash running as +a login shell. Once you have this working, you can copy your initialization +code from ~/.profile to ~/.bash_profile. + +I have received word that the recipe supplied above is insufficient for +machines running CDE. CDE has a maze of twisty little startup files, all +slightly different. + +If you cannot change your login shell in the password file to bash, you +will have to (apparently) live with CDE using the shell in the password +file to run its startup scripts. If you have changed your shell to bash, +there is code in the CDE startup files (on Solaris, at least) that attempts +to do the right thing. It is, however, often broken, and may require that +you use the $BASH_ENV trick described below. + +`dtterm' claims to use $SHELL as the default program to start, so if you +can change $SHELL in the CDE startup files, you should be able to use bash +in your terminal windows. + +Setting DTSOURCEPROFILE in ~/.dtprofile will cause the `Xsession' program +to read your login shell's startup files. You may be able to use bash for +the rest of the CDE programs by setting SHELL to bash in ~/.dtprofile as +well, but I have not tried this. + +You can use the above `exec' recipe to start bash when not logging in with +CDE by testing the value of the DT variable: + + if [ -n "$DT" ]; then + [ -f /usr/gnu/bin/bash ] && exec /usr/gnu/bin/bash --login + fi + +If CDE starts its shells non-interactively during login, the login shell +startup files (~/.profile, ~/.bash_profile) will not be sourced at login. +To get around this problem, append a line similar to the following to your +~/.dtprofile: + + BASH_ENV=${HOME}/.bash_profile ; export BASH_ENV + +and add the following line to the beginning of ~/.bash_profile: + + unset BASH_ENV + +A8) I just changed my login shell to bash, and now I can't FTP into my + machine. Why not? + +You must add the full pathname to bash to the file /etc/shells. As +noted in the answer to the previous question, many systems require +this before you can make bash your login shell. + +Most versions of ftpd use this file to prohibit `special' users +such as `uucp' and `news' from using FTP. + +A9) What's the `POSIX Shell and Utilities standard'? + +POSIX is a name originally coined by Richard Stallman for a +family of open system standards based on UNIX. There are a +number of aspects of UNIX under consideration for +standardization, from the basic system services at the system +call and C library level to applications and tools to system +administration and management. Each area of standardization is +assigned to a working group in the 1003 series. + +The POSIX Shell and Utilities standard was originally developed by +IEEE Working Group 1003.2 (POSIX.2). Today it has been merged with +the original 1003.1 Working Group and is maintained by the Austin +Group (a joint working group of the IEEE, The Open Group and +ISO/IEC SC22/WG15). Today the Shell and Utilities are a volume +within the set of documents that make up IEEE Std 1003.1-2001, and +thus now the former POSIX.2 (from 1992) is now part of the current +POSIX.1 standard (POSIX 1003.1-2001). + +The Shell and Utilities volume concentrates on the command +interpreter interface and utility programs commonly executed from +the command line or by other programs. The standard is freely +available on the web at http://www.UNIX-systems.org/version3/ . +Work continues at the Austin Group on maintenance issues; see +http://www.opengroup.org/austin/ to join the discussions. + +Bash is concerned with the aspects of the shell's behavior defined +by the POSIX Shell and Utilities volume. The shell command +language has of course been standardized, including the basic flow +control and program execution constructs, I/O redirection and +pipelining, argument handling, variable expansion, and quoting. + +The `special' builtins, which must be implemented as part of the +shell to provide the desired functionality, are specified as +being part of the shell; examples of these are `eval' and +`export'. Other utilities appear in the sections of POSIX not +devoted to the shell which are commonly (and in some cases must +be) implemented as builtin commands, such as `read' and `test'. +POSIX also specifies aspects of the shell's interactive +behavior as part of the UPE, including job control and command +line editing. Only vi-style line editing commands have been +standardized; emacs editing commands were left out due to +objections. + +The latest version of the POSIX Shell and Utilities standard is +available (now updated to the 2004 Edition) as part of the Single +UNIX Specification Version 3 at + +http://www.UNIX-systems.org/version3/ + +A10) What is the bash `posix mode'? + +Although bash is an implementation of the POSIX shell +specification, there are areas where the bash default behavior +differs from that spec. The bash `posix mode' changes the bash +behavior in these areas so that it obeys the spec more closely. + +Posix mode is entered by starting bash with the --posix or +'-o posix' option or executing `set -o posix' after bash is running. + +The specific aspects of bash which change when posix mode is +active are listed in the file POSIX in the bash distribution. +They are also listed in a section in the Bash Reference Manual +(from which that file is generated). + +Section B: The latest version + +B1) What's new in version 3.0? + +Bash-3.0 is the third major release of bash. The features introduced +in the intermediate releases following bash-2.05 have been completed. +Support for the bash debugger (a separate project) has been integrated. + +Bash-3.0 contains the following new features (see the manual page for +complete descriptions and the CHANGES and NEWS files in the bash-3.0 +distribution): + +o Features to support the bash debugger have been implemented, and there + is a new `extdebug' option to turn the non-default options on + +o HISTCONTROL is now a colon-separated list of options and has been + extended with a new `erasedups' option that will result in only one + copy of a command being kept in the history list + +o Brace expansion has been extended with a new {x..y} form, producing + sequences of digits or characters + +o Timestamps are now kept with history entries, with an option to save + and restore them from the history file; there is a new HISTTIMEFORMAT + variable describing how to display the timestamps when listing history + entries + +o The `[[' command can now perform extended regular expression (egrep-like) + matching, with matched subexpressions placed in the BASH_REMATCH array + variable + +o A new `pipefail' option causes a pipeline to return a failure status if + any command in it fails + +o The `jobs', `kill', and `wait' builtins now accept job control notation + in their arguments even if job control is not enabled + +o The `gettext' package and libintl have been integrated, and the shell + messages may be translated into other languages + +A short feature history dating from Bash-2.0: + +Bash-2.05b introduced the following new features: + +o support for multibyte characters has been added to both bash and readline + +o the DEBUG trap is now run *before* simple commands, ((...)) commands, + [[...]] conditional commands, and for ((...)) loops + +o the shell now performs arithmetic in the largest integer size the machine + supports (intmax_t) + +o there is a new \D{...} prompt expansion; passes the `...' to strftime(3) + and inserts the result into the expanded prompt + +o there is a new `here-string' redirection operator: <<< word + +o when displaying variables, function attributes and definitions are shown + separately, allowing them to be re-used as input (attempting to re-use + the old output would result in syntax errors). + +o `read' has a new `-u fd' option to read from a specified file descriptor + +o the bash debugger in examples/bashdb has been modified to work with the + new DEBUG trap semantics, the command set has been made more gdb-like, + and the changes to $LINENO make debugging functions work better + +o the expansion of $LINENO inside a shell function is only relative to the + function start if the shell is interactive -- if the shell is running a + script, $LINENO expands to the line number in the script. This is as + POSIX-2001 requires + +Bash-2.05a introduced the following new features: + +o The `printf' builtin has undergone major work + +o There is a new read-only `shopt' option: login_shell, which is set by + login shells and unset otherwise + +o New `\A' prompt string escape sequence; expanding to time in 24-hour + HH:MM format + +o New `-A group/-g' option to complete and compgen; goes group name + completion + +o New [+-]O invocation option to set and unset `shopt' options at startup + +o ksh-like `ERR' trap + +o `for' loops now allow empty word lists after the `in' reserved word + +o new `hard' and `soft' arguments for the `ulimit' builtin + +o Readline can be configured to place the user at the same point on the line + when retrieving commands from the history list + +o Readline can be configured to skip `hidden' files (filenames with a leading + `.' on Unix) when performing completion + +Bash-2.05 introduced the following new features: + +o This version has once again reverted to using locales and strcoll(3) when + processing pattern matching bracket expressions, as POSIX requires. +o Added a new `--init-file' invocation argument as a synonym for `--rcfile', + per the new GNU coding standards. +o The /dev/tcp and /dev/udp redirections now accept service names as well as + port numbers. +o `complete' and `compgen' now take a `-o value' option, which controls some + of the aspects of that compspec. Valid values are: + + default - perform bash default completion if programmable + completion produces no matches + dirnames - perform directory name completion if programmable + completion produces no matches + filenames - tell readline that the compspec produces filenames, + so it can do things like append slashes to + directory names and suppress trailing spaces +o A new loadable builtin, realpath, which canonicalizes and expands symlinks + in pathname arguments. +o When `set' is called without options, it prints function defintions in a + way that allows them to be reused as input. This affects `declare' and + `declare -p' as well. This only happens when the shell is not in POSIX + mode, since POSIX.2 forbids this behavior. + +Bash-2.04 introduced the following new features: + +o Programmable word completion with the new `complete' and `compgen' builtins; + examples are provided in examples/complete/complete-examples +o `history' has a new `-d' option to delete a history entry +o `bind' has a new `-x' option to bind key sequences to shell commands +o The prompt expansion code has new `\j' and `\l' escape sequences +o The `no_empty_cmd_completion' shell option, if enabled, inhibits + command completion when TAB is typed on an empty line +o `help' has a new `-s' option to print a usage synopsis +o New arithmetic operators: var++, var--, ++var, --var, expr1,expr2 (comma) +o New ksh93-style arithmetic for command: + for ((expr1 ; expr2; expr3 )); do list; done +o `read' has new options: `-t', `-n', `-d', `-s' +o The redirection code handles several filenames specially: /dev/fd/N, + /dev/stdin, /dev/stdout, /dev/stderr +o The redirection code now recognizes /dev/tcp/HOST/PORT and + /dev/udp/HOST/PORT and tries to open a TCP or UDP socket, respectively, + to the specified port on the specified host +o The ${!prefix*} expansion has been implemented +o A new FUNCNAME variable, which expands to the name of a currently-executing + function +o The GROUPS variable is no longer readonly +o A new shopt `xpg_echo' variable, to control the behavior of echo with + respect to backslash-escape sequences at runtime +o The NON_INTERACTIVE_LOGIN_SHELLS #define has returned + +The version of Readline released with Bash-2.04, Readline-4.1, had several +new features as well: + +o Parentheses matching is always compiled into readline, and controllable + with the new `blink-matching-paren' variable +o The history-search-forward and history-search-backward functions now leave + point at the end of the line when the search string is empty, like + reverse-search-history, and forward-search-history +o A new function for applications: rl_on_new_line_with_prompt() +o New variables for applications: rl_already_prompted, and rl_gnu_readline_p + + +Bash-2.03 had very few new features, in keeping with the convention +that odd-numbered releases provide mainly bug fixes.

+ +D1) Why does bash run a different version of `command' than + `which command' says it will? + +On many systems, `which' is actually a csh script that assumes +you're running csh. In tcsh, `which' and its cousin `where' +are builtins. On other Unix systems, `which' is a perl script +that uses the PATH environment variable. + +The csh script version reads the csh startup files from your +home directory and uses those to determine which `command' will +be invoked. Since bash doesn't use any of those startup files, +there's a good chance that your bash environment differs from +your csh environment. The bash `type' builtin does everything +`which' does, and will report correct results for the running +shell. If you're really wedded to the name `which', try adding +the following function definition to your .bashrc: + + which() + { + builtin type "$@" + } + +If you're moving from tcsh and would like to bring `where' along +as well, use this function: + + where() + { + builtin type -a "$@" + } + +D2) Why doesn't bash treat brace expansions exactly like csh? + +The only difference between bash and csh brace expansion is that +bash requires a brace expression to contain at least one unquoted +comma if it is to be expanded. Any brace-surrounded word not +containing an unquoted comma is left unchanged by the brace +expansion code. This affords the greatest degree of sh +compatibility. + +Bash, ksh, zsh, and pd-ksh all implement brace expansion this way. + +D3) Why doesn't bash have csh variable modifiers? + +Posix has specified a more powerful, albeit somewhat more cryptic, +mechanism cribbed from ksh, and bash implements it. + +${parameter%word} + Remove smallest suffix pattern. The WORD is expanded to produce + a pattern.

We have provided +a shell script which does most of the work of conversion for you; +this script can be found in ./examples/misc/aliasconv.sh. Here is +how you use it: + +Start csh in the normal way for you. (e.g., `csh') + +Pipe the output of `alias' through `aliasconv.sh', saving the +results into `bash_aliases': + + alias | bash aliasconv.sh >bash_aliases + +Edit `bash_aliases', carefully reading through any created +functions. You will need to change the names of some csh specific +variables to the bash equivalents. The script converts $cwd to +$PWD, $term to $TERM, $home to $HOME, $user to $USER, and $prompt +to $PS1. You may also have to add quotes to avoid unwanted +expansion. + +For example, the csh alias: + + alias cd 'cd \!*; echo $cwd' + +is converted to the bash function: + + cd () { command cd "$@"; echo $PWD ; } + +The only thing that needs to be done is to quote $PWD: + + cd () { command cd "$@"; echo "$PWD" ; } + +Merge the edited file into your ~/.bashrc. + +There is an additional, more ambitious, script in +examples/misc/cshtobash that attempts to convert your entire csh +environment to its bash equivalent. This script can be run as +simply `cshtobash' to convert your normal interactive +environment, or as `cshtobash ~/.login' to convert your login +environment. + +D5) How can I pipe standard output and standard error from one command to + another, like csh does with `|&'? + +Use + command 2>&1 | command2 + +The key is to remember that piping is performed before redirection, so +file descriptor 1 points to the pipe when it is duplicated onto file +descriptor 2. + +D6) Now that I've converted from ksh to bash, are there equivalents to + ksh features like autoloaded functions and the `whence' command? + +There are features in ksh-88 and ksh-93 that do not have direct bash +equivalents. Most, however, can be emulated with very little trouble. + +ksh-88 feature Bash equivalent +-------------- --------------- +compiled-in aliases set up aliases in .bashrc; some ksh aliases are + bash builtins (hash, history, type) +coprocesses named pipe pairs (one for read, one for write) +typeset +f declare -F +cd, print, whence function substitutes in examples/functions/kshenv +autoloaded functions examples/functions/autoload is the same as typeset -fu +read var?prompt read -p prompt var + +ksh-93 feature Bash equivalent +-------------- --------------- +sleep, getconf Bash has loadable versions in examples/loadables +${.sh.version} $BASH_VERSION +print -f printf +hist alias hist=fc +$HISTEDIT $FCEDIT + +Section E: How can I get bash to do certain things, and why does bash do + things the way it does? + +E1) Why is the bash builtin `test' slightly different from /bin/test? + +The specific example used here is [ ! x -o x ], which is false. + +Bash's builtin `test' implements the Posix.2 spec, which can be +summarized as follows (the wording is due to David Korn): + +Here is the set of rules for processing test arguments. + + 0 Args: False + 1 Arg: True iff argument is not null. + 2 Args: If first arg is !, True iff second argument is null. + If first argument is unary, then true if unary test is true + Otherwise error. + 3 Args: If second argument is a binary operator, do binary test of $1 $3 + If first argument is !, negate two argument test of $2 $3 + If first argument is `(' and third argument is `)', do the + one-argument test of the second argument. + Otherwise error. + 4 Args: If first argument is !, negate three argument test of $2 $3 $4. + Otherwise unspecified + 5 or more Args: unspecified. (Historical shells would use their + current algorithm). + +The operators -a and -o are considered binary operators for the purpose +of the 3 Arg case. + +As you can see, the test becomes (not (x or x)), which is false. + +E2) Why does bash sometimes say `Broken pipe'? + +If a sequence of commands appears in a pipeline, and one of the +reading commands finishes before the writer has finished, the +writer receives a SIGPIPE signal. Many other shells special-case +SIGPIPE as an exit status in the pipeline and do not report it. +For example, in: + + ps -aux | head + +`head' can finish before `ps' writes all of its output, and ps +will try to write on a pipe without a reader. In that case, bash +will print `Broken pipe' to stderr when ps is killed by a +SIGPIPE. + +You can build a version of bash that will not report SIGPIPE errors +by uncommenting the definition of DONT_REPORT_SIGPIPE in the file +config-top.h. + +E3) When I have terminal escape sequences in my prompt, why does bash + wrap lines at the wrong column? + +Readline, the line editing library that bash uses, does not know +that the terminal escape sequences do not take up space on the +screen. The redisplay code assumes, unless told otherwise, that +each character in the prompt is a `printable' character that +takes up one character position on the screen. + +You can use the bash prompt expansion facility (see the PROMPTING +section in the manual page) to tell readline that sequences of +characters in the prompt strings take up no screen space. + +Use the \[ escape to begin a sequence of non-printing characters, +and the \] escape to signal the end of such a sequence. + +E4) If I pipe the output of a command into `read variable', why doesn't + the output show up in $variable when the read command finishes? + +This has to do with the parent-child relationship between Unix +processes. It affects all commands run in pipelines, not just +simple calls to `read'. For example, piping a command's output +into a `while' loop that repeatedly calls `read' will result in +the same behavior. + +Each element of a pipeline, even a builtin or shell function, +runs in a separate process, a child of the shell running the +pipeline. A subprocess cannot affect its parent's environment. +When the `read' command sets the variable to the input, that +variable is set only in the subshell, not the parent shell. When +the subshell exits, the value of the variable is lost. + +Many pipelines that end with `read variable' can be converted +into command substitutions, which will capture the output of +a specified command. The output can then be assigned to a +variable: + + grep ^gnu /usr/lib/news/active | wc -l | read ngroup + +can be converted into + + ngroup=$(grep ^gnu /usr/lib/news/active | wc -l) + +This does not, unfortunately, work to split the text among +multiple variables, as read does when given multiple variable +arguments. If you need to do this, you can either use the +command substitution above to read the output into a variable +and chop up the variable using the bash pattern removal +expansion operators or use some variant of the following +approach. + +Say /usr/local/bin/ipaddr is the following shell script: + +#! /bin/sh +host `hostname` | awk '/address/ {print $NF}' + +Instead of using + + /usr/local/bin/ipaddr | read A B C D + +to break the local machine's IP address into separate octets, use + + OIFS="$IFS" + IFS=. + set -- $(/usr/local/bin/ipaddr) + IFS="$OIFS" + A="$1" B="$2" C="$3" D="$4" + +Beware, however, that this will change the shell's positional +parameters. If you need them, you should save them before doing +this. + +This is the general approach -- in most cases you will not need to +set $IFS to a different value. + +Some other user-supplied alternatives include: + +read A B C D << HERE + $(IFS=.; echo $(/usr/local/bin/ipaddr)) +HERE + +and, where process substitution is available, + +read A B C D < <(IFS=.; echo $(/usr/local/bin/ipaddr)) + +E5) I have a bunch of shell scripts that use backslash-escaped characters + in arguments to `echo'. Bash doesn't interpret these characters. Why + not, and how can I make it understand them? + +This is the behavior of echo on most Unix System V machines. + +The bash builtin `echo' is modeled after the 9th Edition +Research Unix version of `echo'. It does not interpret +backslash-escaped characters in its argument strings by default; +it requires the use of the -e option to enable the +interpretation. The System V echo provides no way to disable the +special characters; the bash echo has a -E option to disable +them. + +There is a configuration option that will make bash behave like +the System V echo and interpret things like `\t' by default. Run +configure with the --enable-xpg-echo-default option to turn this +on. Be aware that this will cause some of the tests run when you +type `make tests' to fail. + +There is a shell option, `xpg_echo', settable with `shopt', that will +change the behavior of echo at runtime. Enabling this option turns +on expansion of backslash-escape sequences. + +E6) Why doesn't a while or for loop get suspended when I type ^Z? + +This is a consequence of how job control works on Unix. The only +thing that can be suspended is the process group. This is a single +command or pipeline of commands that the shell forks and executes. + +When you run a while or for loop, the only thing that the shell forks +and executes are any commands in the while loop test and commands in +the loop bodies. These, therefore, are the only things that can be +suspended when you type ^Z. + +If you want to be able to stop the entire loop, you need to put it +within parentheses, which will force the loop into a subshell that +may be stopped (and subsequently restarted) as a single unit. + +E7) What about empty for loops in Makefiles? + +It's fairly common to see constructs like this in automatically-generated +Makefiles: + +SUBDIRS = @SUBDIRS@ + + ... + +subdirs-clean: + for d in ${SUBDIRS}; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +When SUBDIRS is empty, this results in a command like this being passed to +bash: + + for d in ; do + ( cd $d && ${MAKE} ${MFLAGS} clean ) + done + +In versions of bash before bash-2.05a, this was a syntax error. If the +reserved word `in' was present, a word must follow it before the semicolon +or newline. The language in the manual page referring to the list of words +being empty referred to the list after it is expanded. These versions of +bash required that there be at least one word following the `in' when the +construct was parsed. + +The idiomatic Makefile solution is something like: + +SUBDIRS = @SUBDIRS@ + +subdirs-clean: + subdirs=$SUBDIRS ; for d in $$subdirs; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +The latest updated POSIX standard has changed this: the word list +is no longer required. Bash versions 2.05a and later accept the +new syntax. + +E8) Why does the arithmetic evaluation code complain about `08'? + +The bash arithmetic evaluation code (used for `let', $(()), (()), and in +other places), interprets a leading `0' in numeric constants as denoting +an octal number, and a leading `0x' as denoting hexadecimal. This is +in accordance with the POSIX.2 spec, section 2.9.2.1, which states that +arithmetic constants should be handled as signed long integers as defined +by the ANSI/ISO C standard. + +The POSIX.2 interpretation committee has confirmed this: + +http://www.pasc.org/interps/unofficial/db/p1003.2/pasc-1003.2-173.html + +E9) Why does the pattern matching expression [A-Z]* match files beginning + with every letter except `z'? + +Bash-2.03, Bash-2.05 and later versions honor the current locale setting +when processing ranges within pattern matching bracket expressions ([A-Z]). +This is what POSIX.2 and SUSv3/XPG6 specify. + +The behavior of the matcher in bash-2.05 and later versions depends on the +current LC_COLLATE setting. Setting this variable to `C' or `POSIX' will +result in the traditional behavior ([A-Z] matches all uppercase ASCII +characters). Many other locales, including the en_US locale (the default +on many US versions of Linux) collate the upper and lower case letters like +this: + + AaBb...Zz + +which means that [A-Z] matches every letter except `z'. Others collate like + + aAbBcC...zZ + +which means that [A-Z] matches every letter except `a'. + +The portable way to specify upper case letters is [:upper:] instead of +A-Z; lower case may be specified as [:lower:] instead of a-z. + +Look at the manual pages for setlocale(3), strcoll(3), and, if it is +present, locale(1). If you have locale(1), you can use it to find +your current locale information even if you do not have any of the +LC_ variables set. + +My advice is to put + + export LC_COLLATE=C + +into /etc/profile and inspect any shell scripts run from cron for +constructs like [A-Z]. This will prevent things like + + rm [A-Z]* + +from removing every file in the current directory except those beginning +with `z' and still allow individual users to change the collation order. +Users may put the above command into their own profiles as well, of course. + +E10) Why does `cd //' leave $PWD as `//'? + +POSIX.2, in its description of `cd', says that *three* or more leading +slashes may be replaced with a single slash when canonicalizing the +current working directory. + +This is, I presume, for historical compatibility. Certain versions of +Unix, and early network file systems, used paths of the form +//hostname/path to access `path' on server `hostname'. + +E11) If I resize my xterm while another program is running, why doesn't bash + notice the change? + +This is another issue that deals with job control. + +The kernel maintains a notion of a current terminal process group. Members +of this process group (processes whose process group ID is equal to the +current terminal process group ID) receive terminal-generated signals like +SIGWINCH. (For more details, see the JOB CONTROL section of the bash +man page.) + +If a terminal is resized, the kernel sends SIGWINCH to each member of +the terminal's current process group (the `foreground' process group). + +When bash is running with job control enabled, each pipeline (which may be +a single command) is run in its own process group, different from bash's +process group. This foreground process group receives the SIGWINCH; bash +does not. Bash has no way of knowing that the terminal has been resized. + +There is a `checkwinsize' option, settable with the `shopt' builtin, that +will cause bash to check the window size and adjust its idea of the +terminal's dimensions each time a process stops or exits and returns control +of the terminal to bash. Enable it with `shopt -s checkwinsize'. + +E12) Why don't negative offsets in substring expansion work like I expect? + +When substring expansion of the form ${param:offset[:length} is used, +an `offset' that evaluates to a number less than zero counts back from +the end of the expanded value of $param. + +When a negative `offset' begins with a minus sign, however, unexpected things +can happen. Consider + + a=12345678 + echo ${a:-4} + +intending to print the last four characters of $a. The problem is that +${param:-word} already has a well-defined meaning: expand to word if the +expanded value of param is unset or null, and $param otherwise. + +To use negative offsets that begin with a minus sign, separate the +minus sign and the colon with a space. + +Section F: Things to watch out for on certain Unix versions + +F1) Why can't I use command line editing in my `cmdtool'? + +The problem is `cmdtool' and bash fighting over the input. When +scrolling is enabled in a cmdtool window, cmdtool puts the tty in +`raw mode' to permit command-line editing using the mouse for +applications that cannot do it themselves. As a result, bash and +cmdtool each try to read keyboard input immediately, with neither +getting enough of it to be useful. + +This mode also causes cmdtool to not implement many of the +terminal functions and control sequences appearing in the +`sun-cmd' termcap entry. For a more complete explanation, see +that file examples/suncmd.termcap in the bash distribution. + +`xterm' is a better choice, and gets along with bash much more +smoothly. + +If you must use cmdtool, you can use the termcap description in +examples/suncmd.termcap. Set the TERMCAP variable to the terminal +description contained in that file, i.e. + +TERMCAP='Mu|sun-cmd:am:bs:km:pt:li#34:co#80:cl=^L:ce=\E[K:cd=\E[J:rs=\E[s:' + +Then export TERMCAP and start a new cmdtool window from that shell. +The bash command-line editing should behave better in the new +cmdtool. If this works, you can put the assignment to TERMCAP +in your bashrc file. + +F2) I built bash on Solaris 2. Why do globbing expansions and filename + completion chop off the first few characters of each filename? + +This is the consequence of building bash on SunOS 5 and linking +with the libraries in /usr/ucblib, but using the definitions +and structures from files in /usr/include. + +The actual conflict is between the dirent structure in +/usr/include/dirent.h and the struct returned by the version of +`readdir' in libucb.a (a 4.3-BSD style `struct direct'). + +Make sure you've got /usr/ccs/bin ahead of /usr/ucb in your $PATH +when configuring and building bash. This will ensure that you +use /usr/ccs/bin/cc or acc instead of /usr/ucb/cc and that you +link with libc before libucb. + +If you have installed the Sun C compiler, you may also need to +put /usr/ccs/bin and /opt/SUNWspro/bin into your $PATH before +/usr/ucb. + +F3) Why does bash dump core after I interrupt username completion or + `~user' tilde expansion on a machine running NIS? + +This is a famous and long-standing bug in the SunOS YP (sorry, NIS) +client library, which is part of libc. + +The YP library code keeps static state -- a pointer into the data +returned from the server. When YP initializes itself (setpwent), +it looks at this pointer and calls free on it if it's non-null. +So far, so good. + +If one of the YP functions is interrupted during getpwent (the +exact function is interpretwithsave()), and returns NULL, the +pointer is freed without being reset to NULL, and the function +returns. The next time getpwent is called, it sees that this +pointer is non-null, calls free, and the bash free() blows up +because it's being asked to free freed memory. + +The traditional Unix mallocs allow memory to be freed multiple +times; that's probably why this has never been fixed. You can +run configure with the `--without-gnu-malloc' option to use +the C library malloc and avoid the problem. + +F4) I'm running SVR4.2. Why is the line erased every time I type `@'? + +The `@' character is the default `line kill' character in most +versions of System V, including SVR4.2. You can change this +character to whatever you want using `stty'. For example, to +change the line kill character to control-u, type + + stty kill ^U + +where the `^' and `U' can be two separate characters. + +F5) Why does bash report syntax errors when my C News scripts use a + redirection before a subshell command? + +The actual command in question is something like + + < file ( command ) + +According to the grammar given in the POSIX.2 standard, this construct +is, in fact, a syntax error. Redirections may only precede `simple +commands'. A subshell construct such as the above is one of the shell's +`compound commands'. A redirection may only follow a compound command. + +This affects the mechanical transformation of commands that use `cat' +to pipe a file into a command (a favorite Useless-Use-Of-Cat topic on +comp.unix.shell). While most commands of the form + + cat file | command + +can be converted to `< file command', shell control structures such as +loops and subshells require `command < file'. + +The file CWRU/sh-redir-hack in the bash distribution is an +(unofficial) patch to parse.y that will modify the grammar to +support this construct. It will not apply with `patch'; you must +modify parse.y by hand. Note that if you apply this, you must +recompile with -DREDIRECTION_HACK. This introduces a large +number of reduce/reduce conflicts into the shell grammar. + +F6) Why can't I use vi-mode editing on Red Hat Linux 6.1? + +The short answer is that Red Hat screwed up. + +The long answer is that they shipped an /etc/inputrc that only works +for emacs mode editing, and then screwed all the vi users by setting +INPUTRC to /etc/inputrc in /etc/profile. + +The short fix is to do one of the following: remove or rename +/etc/inputrc, set INPUTRC=~/.inputrc in ~/.bashrc (or .bash_profile, +but make sure you export it if you do), remove the assignment to +INPUTRC from /etc/profile, add + + set keymap emacs + +to the beginning of /etc/inputrc, or bracket the key bindings in +/etc/inputrc with these lines + + $if mode=emacs + [...] + $endif + +F7) Why do bash-2.05a and bash-2.05b fail to compile `printf.def' on + HP/UX 11.x? + +HP/UX's support for long double is imperfect at best. + +GCC will support it without problems, but the HP C library functions +like strtold(3) and printf(3) don't actually work with long doubles. +HP implemented a `long_double' type as a 4-element array of 32-bit +ints, and that is what the library functions use. The ANSI C +`long double' type is a 128-bit floating point scalar. + +The easiest fix, until HP fixes things up, is to edit the generated +config.h and #undef the HAVE_LONG_DOUBLE line. After doing that, +the compilation should complete successfully. + +Section G: How can I get bash to do certain common things? + +G1) How can I get bash to read and display eight-bit characters? + +This is a process requiring several steps. + +First, you must ensure that the `physical' data path is a full eight +bits. For xterms, for example, the `vt100' resources `eightBitInput' +and `eightBitOutput' should be set to `true'. + +Once you have set up an eight-bit path, you must tell the kernel and +tty driver to leave the eighth bit of characters alone when processing +keyboard input. Use `stty' to do this: + + stty cs8 -istrip -parenb + +For old BSD-style systems, you can use + + stty pass8 + +You may also need + + stty even odd + +Finally, you need to tell readline that you will be inputting and +displaying eight-bit characters. You use readline variables to do +this. These variables can be set in your .inputrc or using the bash +`bind' builtin. Here's an example using `bind': + + bash$ bind 'set convert-meta off' + bash$ bind 'set meta-flag on' + bash$ bind 'set output-meta on' + +The `set' commands between the single quotes may also be placed +in ~/.inputrc. + +G2) How do I write a function `x' to replace builtin command `x', but + still invoke the command from within the function? + +This is why the `command' and `builtin' builtins exist. The +`command' builtin executes the command supplied as its first +argument, skipping over any function defined with that name. The +`builtin' builtin executes the builtin command given as its first +argument directly. + +For example, to write a function to replace `cd' that writes the +hostname and current directory to an xterm title bar, use +something like the following: + + cd() + { + builtin cd "$@" && xtitle "$HOST: $PWD" + } + +This could also be written using `command' instead of `builtin'; +the version above is marginally more efficient. + +G3) How can I find the value of a shell variable whose name is the value + of another shell variable? + +Versions of Bash newer than Bash-2.0 support this directly. You can use + + ${!var} + +For example, the following sequence of commands will echo `z': + + var1=var2 + var2=z + echo ${!var1} + +For sh compatibility, use the `eval' builtin. The important +thing to remember is that `eval' expands the arguments you give +it again, so you need to quote the parts of the arguments that +you want `eval' to act on. + +For example, this expression prints the value of the last positional +parameter: + + eval echo \"\$\{$#\}\" + +The expansion of the quoted portions of this expression will be +deferred until `eval' runs, while the `$#' will be expanded +before `eval' is executed. In versions of bash later than bash-2.0, + + echo ${!#} + +does the same thing. + +This is not the same thing as ksh93 `nameref' variables, though the syntax +is similar. I may add namerefs in a future bash version. + +G4) How can I make the bash `time' reserved word print timing output that + looks like the output from my system's /usr/bin/time? + +The bash command timing code looks for a variable `TIMEFORMAT' and +uses its value as a format string to decide how to display the +timing statistics. + +The value of TIMEFORMAT is a string with `%' escapes expanded in a +fashion similar in spirit to printf(3). The manual page explains +the meanings of the escape sequences in the format string. + +If TIMEFORMAT is not set, bash acts as if the following assignment had +been performed: + + TIMEFORMAT=$'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS' + +The POSIX.2 default time format (used by `time -p command') is + + TIMEFORMAT=$'real %2R\nuser %2U\nsys %2S' + +The BSD /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\t%1R real\t%1U user\t%1S sys' + +The System V /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\nreal\t%1R\nuser\t%1U\nsys\t%1S' + +The ksh format can be emulated with: + + TIMEFORMAT=$'\nreal\t%2lR\nuser\t%2lU\nsys\t%2lS' + +G5) How do I get the current directory into my prompt? + +Bash provides a number of backslash-escape sequences which are expanded +when the prompt string (PS1 or PS2) is displayed. The full list is in +the manual page. + +The \w expansion gives the full pathname of the current directory, with +a tilde (`~') substituted for the current value of $HOME. The \W +expansion gives the basename of the current directory. To put the full +pathname of the current directory into the path without any tilde +subsitution, use $PWD. Here are some examples: + + PS1='\w$ ' # current directory with tilde + PS1='\W$ ' # basename of current directory + PS1='$PWD$ ' # full pathname of current directory + +The single quotes are important in the final example to prevent $PWD from +being expanded when the assignment to PS1 is performed. + +G6) How can I rename "*.foo" to "*.bar"? + +Use the pattern removal functionality described in D3. The following `for' +loop will do the trick: + + for f in *.foo; do + mv $f ${f%foo}bar + done + +G7) How can I translate a filename from uppercase to lowercase? + +The script examples/functions/lowercase, originally written by John DuBois, +will do the trick. The converse is left as an exercise. + +G8) How can I write a filename expansion (globbing) pattern that will match + all files in the current directory except "." and ".."? + +You must have set the `extglob' shell option using `shopt -s extglob' to use +this: + + echo .!(.|) * + +A solution that works without extended globbing is given in the Unix Shell +FAQ, posted periodically to comp.unix.shell. + +Section H: Where do I go from here? + +H1) How do I report bugs in bash, and where should I look for fixes and + advice? + +Use the `bashbug' script to report bugs. It is built and +installed at the same time as bash. It provides a standard +template for reporting a problem and automatically includes +information about your configuration and build environment. + +`bashbug' sends its reports to bug-bash@gnu.org, which +is a large mailing list gatewayed to the usenet newsgroup gnu.bash.bug. + +Bug fixes, answers to questions, and announcements of new releases +are all posted to gnu.bash.bug. Discussions concerning bash features +and problems also take place there. + +To reach the bash maintainers directly, send mail to +bash-maintainers@gnu.org. + +H2) What kind of bash documentation is there? + +First, look in the doc directory in the bash distribution. It should +contain at least the following files: + +bash.1 an extensive, thorough Unix-style manual page +builtins.1 a manual page covering just bash builtin commands +bashref.texi a reference manual in GNU tex`info format +bashref.info an info version of the reference manual +FAQ this file +article.ms text of an article written for The Linux Journal +readline.3 a man page describing readline + +Postscript, HTML, and ASCII files created from the above source are +available in the documentation distribution. + +There is additional documentation available for anonymous FTP from host +ftp.cwru.edu in the `pub/bash' directory. + +Cameron Newham and Bill Rosenblatt have written a book on bash, published +by O'Reilly and Associates. The book is based on Bill Rosenblatt's Korn +Shell book. The title is ``Learning the Bash Shell'', and the ISBN number +is 1-56592-147-X. Look for it in fine bookstores near you. This book +covers bash-1.14, but has an appendix describing some of the new features +in bash-2.0. + +A second edition of this book is available, published in January, 1998. +The ISBN number is 1-56592-347-2. Look for it in the same fine bookstores +or on the web. + +The GNU Bash Reference Manual has been published as a printed book by +Network Theory Ltd (Paperback, ISBN: 0-9541617-7-7, Feb 2003). It covers +bash-2.0 and is available from most online bookstores (see +http://www.network-theory.co.uk/bash/manual/ for details).

It is an implementation of +the Posix 1003.2 shell standard, and resembles the Korn and System V +shells. + +Bash contains a number of enhancements over those shells, both +for interactive use and shell programming. Features geared +toward interactive use include command line editing, command +history, job control, aliases, and prompt expansion. Programming +features include additional variable expansions, shell +arithmetic, and a number of variables and options to control +shell behavior. + +Bash was originally written by Brian Fox of the Free Software +Foundation. The current developer and maintainer is Chet Ramey +of Case Western Reserve University. + +A2) What's the latest version? + +The latest version is 2.05b, first made available on Wednesday, 17 +July, 2002. + +A3) Where can I get it? + +Bash is the GNU project's shell, and so is available from the +master GNU archive site, ftp.gnu.org, and its mirrors. The +latest version is also available for FTP from ftp.cwru.edu. +The following URLs tell how to get version 2.05b: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-2.05b.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-2.05b.tar.gz + +Formatted versions of the documentation are available with the URLs: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-doc-2.05b.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-doc-2.05b.tar.gz + +A4) On what machines will bash run? + +Bash has been ported to nearly every version of UNIX. All you +should have to do to build it on a machine for which a port +exists is to type `configure' and then `make'. The build process +will attempt to discover the version of UNIX you have and tailor +itself accordingly, using a script created by GNU autoconf. + +More information appears in the file `INSTALL' in the distribution. + +The Bash web page (http://cnswww.cns.cwru.edu/~chet/bash/bashtop.html) +explains how to obtain binary versions of bash for most of the major +commercial Unix systems. + +A5) Will bash run on operating systems other than Unix? + +Configuration specifics for Unix-like systems such as QNX and +LynxOS are included in the distribution. Bash-2.05 and later +versions should compile and run on Minix 2.0 (patches were +contributed), but I don't believe anyone has built bash-2.x on +earlier Minix versions yet. + +Bash has been ported to versions of Windows implementing the Win32 +programming interface. This includes Windows 95 and Windows NT. +The port was done by Cygnus Solutions as part of their CYGWIN +project. For more information about the project, look at the URLs + +http://www.cygwin.com/ +http://sourceware.cygnus.com/cygwin + +Cygnus originally ported bash-1.14.7, and that port was part of their +early GNU-Win32 (the original name) releases. Cygnus has also done a +port of bash-2.05 to the CYGWIN environment, and it is available as +part of their current release. + +Bash-2.05b should require no local Cygnus changes to build and run under +CYGWIN. + +The Cygnus port works only on Intel machines. There is a port of bash +(I don't know which version) to the alpha/NT environment available from + +ftp://ftp.gnustep.org//pub/win32/bash-alpha-nt-1.01.tar.gz + +DJ Delorie has a port of bash-2.x which runs under MS-DOS, as part +of the DJGPP project. For more information on the project, see + +http://www.delorie.com/djgpp/ + +I have been told that the original DJGPP port was done by Daisuke Aoyama. + +Mark Elbrecht has sent me notice that bash-2.04 +is available for DJGPP V2.

Beware. + +I have received word that Bash (I'm not sure which version, but I +believe that it's at least bash-2.02.1) is the standard shell on +BeOS. + +A6) How can I build bash with gcc? + +Bash configures to use gcc by default if it is available. Read the +file INSTALL in the distribution for more information. + +A7) How can I make bash my login shell? + +Some machines let you use `chsh' to change your login shell. Other +systems use `passwd -s' or `passwd -e'. If one of these works for +you, that's all you need. Note that many systems require the full +pathname to a shell to appear in /etc/shells before you can make it +your login shell. For this, you may need the assistance of your +friendly local system administrator. + +If you cannot do this, you can still use bash as your login shell, but +you need to perform some tricks. The basic idea is to add a command +to your login shell's startup file to replace your login shell with +bash. + +For example, if your login shell is csh or tcsh, and you have installed +bash in /usr/gnu/bin/bash, add the following line to ~/.login: + + if ( -f /usr/gnu/bin/bash ) exec /usr/gnu/bin/bash --login + +(the `--login' tells bash that it is a login shell). + +It's not a good idea to put this command into ~/.cshrc, because every +csh you run without the `-f' option, even ones started to run csh scripts, +reads that file. If you must put the command in ~/.cshrc, use something +like + + if ( $?prompt ) exec /usr/gnu/bin/bash --login + +to ensure that bash is exec'd only when the csh is interactive. + +If your login shell is sh or ksh, you have to do two things. + +First, create an empty file in your home directory named `.bash_profile'. +The existence of this file will prevent the exec'd bash from trying to +read ~/.profile, and re-execing itself over and over again. ~/.bash_profile +is the first file bash tries to read initialization commands from when +it is invoked as a login shell. + +Next, add a line similar to the above to ~/.profile: + + [ -f /usr/gnu/bin/bash ] && [ -x /usr/gnu/bin/bash ] && \ + exec /usr/gnu/bin/bash --login + +This will cause login shells to replace themselves with bash running as +a login shell. Once you have this working, you can copy your initialization +code from ~/.profile to ~/.bash_profile. + +I have received word that the recipe supplied above is insufficient for +machines running CDE. CDE has a maze of twisty little startup files, all +slightly different. + +If you cannot change your login shell in the password file to bash, you +will have to (apparently) live with CDE using the shell in the password +file to run its startup scripts. If you have changed your shell to bash, +there is code in the CDE startup files (on Solaris, at least) that attempts +to do the right thing. It is, however, often broken, and may require that +you use the $BASH_ENV trick described below. + +`dtterm' claims to use $SHELL as the default program to start, so if you +can change $SHELL in the CDE startup files, you should be able to use bash +in your terminal windows. + +Setting DTSOURCEPROFILE in ~/.dtprofile will cause the `Xsession' program +to read your login shell's startup files. You may be able to use bash for +the rest of the CDE programs by setting SHELL to bash in ~/.dtprofile as +well, but I have not tried this. + +You can use the above `exec' recipe to start bash when not logging in with +CDE by testing the value of the DT variable: + + if [ -n "$DT" ]; then + [ -f /usr/gnu/bin/bash ] && exec /usr/gnu/bin/bash --login + fi + +If CDE starts its shells non-interactively during login, the login shell +startup files (~/.profile, ~/.bash_profile) will not be sourced at login. +To get around this problem, append a line similar to the following to your +~/.dtprofile: + + BASH_ENV=${HOME}/.bash_profile ; export BASH_ENV + +and add the following line to the beginning of ~/.bash_profile: + + unset BASH_ENV + +A8) I just changed my login shell to bash, and now I can't FTP into my + machine. Why not? + +You must add the full pathname to bash to the file /etc/shells. As +noted in the answer to the previous question, many systems require +this before you can make bash your login shell. + +Most versions of ftpd use this file to prohibit `special' users +such as `uucp' and `news' from using FTP. + +A9) What's the `POSIX 1003.2 standard'? + +POSIX is a name originally coined by Richard Stallman for a +family of open system standards based on UNIX. There are a +number of aspects of UNIX under consideration for +standardization, from the basic system services at the system +call and C library level to applications and tools to system +administration and management. Each area of standardization is +assigned to a working group in the 1003 series. + +The POSIX Shell and Utilities standard has been developed by IEEE +Working Group 1003.2 (POSIX.2). It concentrates on the command +interpreter interface and utility programs commonly executed from +the command line or by other programs. An initial version of the +standard has been approved and published by the IEEE, and work is +currently underway to update it. + +Bash is concerned with the aspects of the shell's behavior +defined by POSIX.2. The shell command language has of course +been standardized, including the basic flow control and program +execution constructs, I/O redirection and pipelining, argument +handling, variable expansion, and quoting. + +The `special' builtins, which must be implemented as part of the +shell to provide the desired functionality, are specified as +being part of the shell; examples of these are `eval' and +`export'. Other utilities appear in the sections of POSIX.2 not +devoted to the shell which are commonly (and in some cases must +be) implemented as builtin commands, such as `read' and `test'. +POSIX.2 also specifies aspects of the shell's interactive +behavior as part of the UPE, including job control and command +line editing. Only vi-style line editing commands have been +standardized; emacs editing commands were left out due to +objections. + +The Open Group has made an older version of its Single Unix +Specification (version 2), which is very similar to POSIX.2, +available on the web at + +http://www.opengroup.org/onlinepubs/007908799/ + +The Single Unix Specification, version 3, is available on the web at + +http://www.opengroup.org/onlinepubs/007904975/ + +A10) What is the bash `posix mode'? + +Although bash is an implementation of the POSIX.2 shell +specification, there are areas where the bash default behavior +differs from that spec. The bash `posix mode' changes the bash +behavior in these areas so that it obeys the spec more closely. + +Posix mode is entered by starting bash with the --posix or +'-o posix' option or executing `set -o posix' after bash is running. + +The specific aspects of bash which change when posix mode is +active are listed in the file POSIX in the bash distribution. +They are also listed in a section in the Bash Reference Manual +(from which that file is generated). + +Section B: The latest version + +B1) What's new in version 2.05b? + +The raison d'etre for bash-2.05b is to make a second intermediate +release containing the first of the new features to be available +in bash-3.0 and get feedback on those features before proceeding. +The major new feature is multibyte character support in both Bash +and Readline. + +Bash-2.05b contains the following new features (see the manual page for +complete descriptions and the CHANGES and NEWS files in the bash-2.05b +distribution): + +o support for multibyte characters has been added to both bash and readline + +o the DEBUG trap is now run *before* simple commands, ((...)) commands, + [[...]] conditional commands, and for ((...)) loops + +o the shell now performs arithmetic in the largest integer size the machine + supports (intmax_t) + +o there is a new \D{...} prompt expansion; passes the `...' to strftime(3) + and inserts the result into the expanded prompt + +o there is a new `here-string' redirection operator: <<< word + +o when displaying variables, function attributes and definitions are shown + separately, allowing them to be re-used as input (attempting to re-use + the old output would result in syntax errors). + +o `read' has a new `-u fd' option to read from a specified file descriptor + +o the bash debugger in examples/bashdb has been modified to work with the + new DEBUG trap semantics, the command set has been made more gdb-like, + and the changes to $LINENO make debugging functions work better + +o the expansion of $LINENO inside a shell function is only relative to the + function start if the shell is interactive -- if the shell is running a + script, $LINENO expands to the line number in the script. This is as + POSIX-2001 requires + + +A short feature history dating from Bash-2.0: + +Bash-2.05a introduced the following new features: + +o The `printf' builtin has undergone major work + +o There is a new read-only `shopt' option: login_shell, which is set by + login shells and unset otherwise + +o New `\A' prompt string escape sequence; expanding to time in 24-hour + HH:MM format + +o New `-A group/-g' option to complete and compgen; goes group name + completion + +o New [+-]O invocation option to set and unset `shopt' options at startup + +o ksh-like `ERR' trap + +o `for' loops now allow empty word lists after the `in' reserved word + +o new `hard' and `soft' arguments for the `ulimit' builtin + +o Readline can be configured to place the user at the same point on the line + when retrieving commands from the history list + +o Readline can be configured to skip `hidden' files (filenames with a leading + `.' on Unix) when performing completion + +Bash-2.05 introduced the following new features: + +o This version has once again reverted to using locales and strcoll(3) when + processing pattern matching bracket expressions, as POSIX requires. +o Added a new `--init-file' invocation argument as a synonym for `--rcfile', + per the new GNU coding standards. +o The /dev/tcp and /dev/udp redirections now accept service names as well as + port numbers. +o `complete' and `compgen' now take a `-o value' option, which controls some + of the aspects of that compspec. Valid values are: + + default - perform bash default completion if programmable + completion produces no matches + dirnames - perform directory name completion if programmable + completion produces no matches + filenames - tell readline that the compspec produces filenames, + so it can do things like append slashes to + directory names and suppress trailing spaces +o A new loadable builtin, realpath, which canonicalizes and expands symlinks + in pathname arguments. +o When `set' is called without options, it prints function defintions in a + way that allows them to be reused as input. This affects `declare' and + `declare -p' as well. This only happens when the shell is not in POSIX + mode, since POSIX.2 forbids this behavior. + +Bash-2.04 introduced the following new features: + +o Programmable word completion with the new `complete' and `compgen' builtins; + examples are provided in examples/complete/complete-examples +o `history' has a new `-d' option to delete a history entry +o `bind' has a new `-x' option to bind key sequences to shell commands +o The prompt expansion code has new `\j' and `\l' escape sequences +o The `no_empty_cmd_completion' shell option, if enabled, inhibits + command completion when TAB is typed on an empty line +o `help' has a new `-s' option to print a usage synopsis +o New arithmetic operators: var++, var--, ++var, --var, expr1,expr2 (comma) +o New ksh93-style arithmetic for command: + for ((expr1 ; expr2; expr3 )); do list; done +o `read' has new options: `-t', `-n', `-d', `-s' +o The redirection code handles several filenames specially: /dev/fd/N, + /dev/stdin, /dev/stdout, /dev/stderr +o The redirection code now recognizes /dev/tcp/HOST/PORT and + /dev/udp/HOST/PORT and tries to open a TCP or UDP socket, respectively, + to the specified port on the specified host +o The ${!prefix*} expansion has been implemented +o A new FUNCNAME variable, which expands to the name of a currently-executing + function +o The GROUPS variable is no longer readonly +o A new shopt `xpg_echo' variable, to control the behavior of echo with + respect to backslash-escape sequences at runtime +o The NON_INTERACTIVE_LOGIN_SHELLS #define has returned + +The version of Readline released with Bash-2.04, Readline-4.1, had several +new features as well: + +o Parentheses matching is always compiled into readline, and controllable + with the new `blink-matching-paren' variable +o The history-search-forward and history-search-backward functions now leave + point at the end of the line when the search string is empty, like + reverse-search-history, and forward-search-history +o A new function for applications: rl_on_new_line_with_prompt() +o New variables for applications: rl_already_prompted, and rl_gnu_readline_p + + +Bash-2.03 had very few new features, in keeping with the convention +that odd-numbered releases provide mainly bug fixes.

+ +D1) Why does bash run a different version of `command' than + `which command' says it will? + +On many systems, `which' is actually a csh script that assumes +you're running csh. In tcsh, `which' and its cousin `where' +are builtins. On other Unix systems, `which' is a perl script +that uses the PATH environment variable. + +The csh script version reads the csh startup files from your +home directory and uses those to determine which `command' will +be invoked. Since bash doesn't use any of those startup files, +there's a good chance that your bash environment differs from +your csh environment. The bash `type' builtin does everything +`which' does, and will report correct results for the running +shell. If you're really wedded to the name `which', try adding +the following function definition to your .bashrc: + + which() + { + builtin type "$@" + } + +If you're moving from tcsh and would like to bring `where' along +as well, use this function: + + where() + { + builtin type -a "$@" + } + +D2) Why doesn't bash treat brace expansions exactly like csh? + +The only difference between bash and csh brace expansion is that +bash requires a brace expression to contain at least one unquoted +comma if it is to be expanded. Any brace-surrounded word not +containing an unquoted comma is left unchanged by the brace +expansion code. This affords the greatest degree of sh +compatibility. + +Bash, ksh, zsh, and pd-ksh all implement brace expansion this way. + +D3) Why doesn't bash have csh variable modifiers? + +Posix has specified a more powerful, albeit somewhat more cryptic, +mechanism cribbed from ksh, and bash implements it. + +${parameter%word} + Remove smallest suffix pattern. The WORD is expanded to produce + a pattern. It then expands to the value of PARAMETER, with the + smallest portion of the suffix matched by the pattern deleted. + + x=file.c + echo ${x%.c}.o + -->file.o + +${parameter%%word} + + Remove largest suffix pattern. The WORD is expanded to produce + a pattern. It then expands to the value of PARAMETER, with the + largest portion of the suffix matched by the pattern deleted. + + x=posix/src/std + echo ${x%%/*} + -->posix + +${parameter#word} + Remove smallest prefix pattern. The WORD is expanded to produce + a pattern. It then expands to the value of PARAMETER, with the + smallest portion of the prefix matched by the pattern deleted. + + x=$HOME/src/cmd + echo ${x#$HOME} + -->/src/cmd + +${parameter##word} + Remove largest prefix pattern. The WORD is expanded to produce + a pattern.

We have provided +a shell script which does most of the work of conversion for you; +this script can be found in ./examples/misc/aliasconv.sh. Here is +how you use it: + +Start csh in the normal way for you. (e.g., `csh') + +Pipe the output of `alias' through `aliasconv.sh', saving the +results into `bash_aliases': + + alias | bash aliasconv.sh >bash_aliases + +Edit `bash_aliases', carefully reading through any created +functions. You will need to change the names of some csh specific +variables to the bash equivalents. The script converts $cwd to +$PWD, $term to $TERM, $home to $HOME, $user to $USER, and $prompt +to $PS1. You may also have to add quotes to avoid unwanted +expansion. + +For example, the csh alias: + + alias cd 'cd \!*; echo $cwd' + +is converted to the bash function: + + cd () { command cd "$@"; echo $PWD ; } + +The only thing that needs to be done is to quote $PWD: + + cd () { command cd "$@"; echo "$PWD" ; } + +Merge the edited file into your ~/.bashrc. + +There is an additional, more ambitious, script in +examples/misc/cshtobash that attempts to convert your entire csh +environment to its bash equivalent. This script can be run as +simply `cshtobash' to convert your normal interactive +environment, or as `cshtobash ~/.login' to convert your login +environment. + +D5) How can I pipe standard output and standard error from one command to + another, like csh does with `|&'? + +Use + command 2>&1 | command2 + +The key is to remember that piping is performed before redirection, so +file descriptor 1 points to the pipe when it is duplicated onto file +descriptor 2. + +D6) Now that I've converted from ksh to bash, are there equivalents to + ksh features like autoloaded functions and the `whence' command? + +There are features in ksh-88 and ksh-93 that do not have direct bash +equivalents. Most, however, can be emulated with very little trouble. + +ksh-88 feature Bash equivalent +-------------- --------------- +compiled-in aliases set up aliases in .bashrc; some ksh aliases are + bash builtins (hash, history, type) +coprocesses named pipe pairs (one for read, one for write) +typeset +f declare -F +cd, print, whence function substitutes in examples/functions/kshenv +autoloaded functions examples/functions/autoload is the same as typeset -fu +read var?prompt read -p prompt var + +ksh-93 feature Bash equivalent +-------------- --------------- +sleep, getconf Bash has loadable versions in examples/loadables +${.sh.version} $BASH_VERSION +print -f printf +hist alias hist=fc +$HISTEDIT $FCEDIT + +Section E: How can I get bash to do certain things, and why does bash do + things the way it does? + +E1) Why is the bash builtin `test' slightly different from /bin/test? + +The specific example used here is [ ! x -o x ], which is false. + +Bash's builtin `test' implements the Posix.2 spec, which can be +summarized as follows (the wording is due to David Korn): + +Here is the set of rules for processing test arguments. + + 0 Args: False + 1 Arg: True iff argument is not null. + 2 Args: If first arg is !, True iff second argument is null. + If first argument is unary, then true if unary test is true + Otherwise error. + 3 Args: If second argument is a binary operator, do binary test of $1 $3 + If first argument is !, negate two argument test of $2 $3 + If first argument is `(' and third argument is `)', do the + one-argument test of the second argument. + Otherwise error. + 4 Args: If first argument is !, negate three argument test of $2 $3 $4. + Otherwise unspecified + 5 or more Args: unspecified. (Historical shells would use their + current algorithm). + +The operators -a and -o are considered binary operators for the purpose +of the 3 Arg case. + +As you can see, the test becomes (not (x or x)), which is false. + +E2) Why does bash sometimes say `Broken pipe'? + +If a sequence of commands appears in a pipeline, and one of the +reading commands finishes before the writer has finished, the +writer receives a SIGPIPE signal. Many other shells special-case +SIGPIPE as an exit status in the pipeline and do not report it. +For example, in: + + ps -aux | head + +`head' can finish before `ps' writes all of its output, and ps +will try to write on a pipe without a reader. In that case, bash +will print `Broken pipe' to stderr when ps is killed by a +SIGPIPE. + +You can build a version of bash that will not report SIGPIPE errors +by uncommenting the definition of DONT_REPORT_SIGPIPE in the file +config-top.h. + +E3) When I have terminal escape sequences in my prompt, why does bash + wrap lines at the wrong column? + +Readline, the line editing library that bash uses, does not know +that the terminal escape sequences do not take up space on the +screen. The redisplay code assumes, unless told otherwise, that +each character in the prompt is a `printable' character that +takes up one character position on the screen. + +You can use the bash prompt expansion facility (see the PROMPTING +section in the manual page) to tell readline that sequences of +characters in the prompt strings take up no screen space. + +Use the \[ escape to begin a sequence of non-printing characters, +and the \] escape to signal the end of such a sequence. + +E4) If I pipe the output of a command into `read variable', why doesn't + the output show up in $variable when the read command finishes? + +This has to do with the parent-child relationship between Unix +processes. It affects all commands run in pipelines, not just +simple calls to `read'. For example, piping a command's output +into a `while' loop that repeatedly calls `read' will result in +the same behavior. + +Each element of a pipeline runs in a separate process, a child of +the shell running the pipeline. A subprocess cannot affect its +parent's environment. When the `read' command sets the variable +to the input, that variable is set only in the subshell, not the +parent shell. When the subshell exits, the value of the variable +is lost. + +Many pipelines that end with `read variable' can be converted +into command substitutions, which will capture the output of +a specified command. The output can then be assigned to a +variable: + + grep ^gnu /usr/lib/news/active | wc -l | read ngroup + +can be converted into + + ngroup=$(grep ^gnu /usr/lib/news/active | wc -l) + +This does not, unfortunately, work to split the text among +multiple variables, as read does when given multiple variable +arguments. If you need to do this, you can either use the +command substitution above to read the output into a variable +and chop up the variable using the bash pattern removal +expansion operators or use some variant of the following +approach. + +Say /usr/local/bin/ipaddr is the following shell script: + +#! /bin/sh +host `hostname` | awk '/address/ {print $NF}' + +Instead of using + + /usr/local/bin/ipaddr | read A B C D + +to break the local machine's IP address into separate octets, use + + OIFS="$IFS" + IFS=. + set -- $(/usr/local/bin/ipaddr) + IFS="$OIFS" + A="$1" B="$2" C="$3" D="$4" + +Beware, however, that this will change the shell's positional +parameters. If you need them, you should save them before doing +this. + +This is the general approach -- in most cases you will not need to +set $IFS to a different value. + +Some other user-supplied alternatives include: + +read A B C D << HERE + $(IFS=.; echo $(/usr/local/bin/ipaddr)) +HERE + +and, where process substitution is available, + +read A B C D < <(IFS=.; echo $(/usr/local/bin/ipaddr)) + +E5) I have a bunch of shell scripts that use backslash-escaped characters + in arguments to `echo'. Bash doesn't interpret these characters. Why + not, and how can I make it understand them? + +This is the behavior of echo on most Unix System V machines. + +The bash builtin `echo' is modeled after the 9th Edition +Research Unix version of `echo'. It does not interpret +backslash-escaped characters in its argument strings by default; +it requires the use of the -e option to enable the +interpretation. The System V echo provides no way to disable the +special characters; the bash echo has a -E option to disable +them. + +There is a configuration option that will make bash behave like +the System V echo and interpret things like `\t' by default. Run +configure with the --enable-xpg-echo-default option to turn this +on. Be aware that this will cause some of the tests run when you +type `make tests' to fail. + +There is a shell option, `xpg_echo', settable with `shopt', that will +change the behavior of echo at runtime. Enabling this option turns +on expansion of backslash-escape sequences. + +E6) Why doesn't a while or for loop get suspended when I type ^Z? + +This is a consequence of how job control works on Unix. The only +thing that can be suspended is the process group. This is a single +command or pipeline of commands that the shell forks and executes. + +When you run a while or for loop, the only thing that the shell forks +and executes are any commands in the while loop test and commands in +the loop bodies. These, therefore, are the only things that can be +suspended when you type ^Z. + +If you want to be able to stop the entire loop, you need to put it +within parentheses, which will force the loop into a subshell that +may be stopped (and subsequently restarted) as a single unit. + +E7) What about empty for loops in Makefiles? + +It's fairly common to see constructs like this in automatically-generated +Makefiles: + +SUBDIRS = @SUBDIRS@ + + ... + +subdirs-clean: + for d in ${SUBDIRS}; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +When SUBDIRS is empty, this results in a command like this being passed to +bash: + + for d in ; do + ( cd $d && ${MAKE} ${MFLAGS} clean ) + done + +In versions of bash before bash-2.05a, this was a syntax error. If the +reserved word `in' was present, a word must follow it before the semicolon +or newline. The language in the manual page referring to the list of words +being empty referred to the list after it is expanded. These versions of +bash required that there be at least one word following the `in' when the +construct was parsed. + +The idiomatic Makefile solution is something like: + +SUBDIRS = @SUBDIRS@ + +subdirs-clean: + subdirs=$SUBDIRS ; for d in $$subdirs; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +The latest drafts of the updated POSIX standard have changed this: the +word list is no longer required. Bash versions 2.05a and later accept +the new syntax. + +E8) Why does the arithmetic evaluation code complain about `08'? + +The bash arithmetic evaluation code (used for `let', $(()), (()), and in +other places), interprets a leading `0' in numeric constants as denoting +an octal number, and a leading `0x' as denoting hexadecimal. This is +in accordance with the POSIX.2 spec, section 2.9.2.1, which states that +arithmetic constants should be handled as signed long integers as defined +by the ANSI/ISO C standard. + +The POSIX.2 interpretation committee has confirmed this: + +http://www.pasc.org/interps/unofficial/db/p1003.2/pasc-1003.2-173.html + +E9) Why does the pattern matching expression [A-Z]* match files beginning + with every letter except `z'? + +Bash-2.03, Bash-2.05 and later versions honor the current locale setting +when processing ranges within pattern matching bracket expressions ([A-Z]). +This is what POSIX.2 and SUSv3/XPG6 specify. + +The behavior of the matcher in bash-2.05 and later versions depends on the +current LC_COLLATE setting. Setting this variable to `C' or `POSIX' will +result in the traditional behavior ([A-Z] matches all uppercase ASCII +characters). Many other locales, including the en_US locale (the default +on many US versions of Linux) collate the upper and lower case letters like +this: + + AaBb...Zz + +which means that [A-Z] matches every letter except `z'. Others collate like + + aAbBcC...zZ + +which means that [A-Z] matches every letter except `a'. + +The portable way to specify upper case letters is [:upper:] instead of +A-Z; lower case may be specified as [:lower:] instead of a-z. + +Look at the manual pages for setlocale(3), strcoll(3), and, if it is +present, locale(1). If you have locale(1), you can use it to find +your current locale information even if you do not have any of the +LC_ variables set. + +My advice is to put + + export LC_COLLATE=C + +into /etc/profile and inspect any shell scripts run from cron for +constructs like [A-Z]. This will prevent things like + + rm [A-Z]* + +from removing every file in the current directory except those beginning +with `z' and still allow individual users to change the collation order. +Users may put the above command into their own profiles as well, of course. + +E10) Why does `cd //' leave $PWD as `//'? + +POSIX.2, in its description of `cd', says that *three* or more leading +slashes may be replaced with a single slash when canonicalizing the +current working directory. + +This is, I presume, for historical compatibility. Certain versions of +Unix, and early network file systems, used paths of the form +//hostname/path to access `path' on server `hostname'. + +E11) If I resize my xterm while another program is running, why doesn't bash + notice the change? + +This is another issue that deals with job control. + +The kernel maintains a notion of a current terminal process group. Members +of this process group (processes whose process group ID is equal to the +current terminal process group ID) receive terminal-generated signals like +SIGWINCH. (For more details, see the JOB CONTROL section of the bash +man page.) + +If a terminal is resized, the kernel sends SIGWINCH to each member of +the terminal's current process group (the `foreground' process group). + +When bash is running with job control enabled, each pipeline (which may be +a single command) is run in its own process group, different from bash's +process group. This foreground process group receives the SIGWINCH; bash +does not. Bash has no way of knowing that the terminal has been resized. + +There is a `checkwinsize' option, settable with the `shopt' builtin, that +will cause bash to check the window size and adjust its idea of the +terminal's dimensions each time a process stops or exits and returns control +of the terminal to bash. Enable it with `shopt -s checkwinsize'. + +Section F: Things to watch out for on certain Unix versions + +F1) Why can't I use command line editing in my `cmdtool'? + +The problem is `cmdtool' and bash fighting over the input. When +scrolling is enabled in a cmdtool window, cmdtool puts the tty in +`raw mode' to permit command-line editing using the mouse for +applications that cannot do it themselves. As a result, bash and +cmdtool each try to read keyboard input immediately, with neither +getting enough of it to be useful. + +This mode also causes cmdtool to not implement many of the +terminal functions and control sequences appearing in the +`sun-cmd' termcap entry. For a more complete explanation, see +that file examples/suncmd.termcap in the bash distribution. + +`xterm' is a better choice, and gets along with bash much more +smoothly. + +If you must use cmdtool, you can use the termcap description in +examples/suncmd.termcap. Set the TERMCAP variable to the terminal +description contained in that file, i.e. + +TERMCAP='Mu|sun-cmd:am:bs:km:pt:li#34:co#80:cl=^L:ce=\E[K:cd=\E[J:rs=\E[s:' + +Then export TERMCAP and start a new cmdtool window from that shell. +The bash command-line editing should behave better in the new +cmdtool. If this works, you can put the assignment to TERMCAP +in your bashrc file. + +F2) I built bash on Solaris 2. Why do globbing expansions and filename + completion chop off the first few characters of each filename? + +This is the consequence of building bash on SunOS 5 and linking +with the libraries in /usr/ucblib, but using the definitions +and structures from files in /usr/include. + +The actual conflict is between the dirent structure in +/usr/include/dirent.h and the struct returned by the version of +`readdir' in libucb.a (a 4.3-BSD style `struct direct'). + +Make sure you've got /usr/ccs/bin ahead of /usr/ucb in your $PATH +when configuring and building bash. This will ensure that you +use /usr/ccs/bin/cc or acc instead of /usr/ucb/cc and that you +link with libc before libucb. + +If you have installed the Sun C compiler, you may also need to +put /usr/ccs/bin and /opt/SUNWspro/bin into your $PATH before +/usr/ucb. + +F3) Why does bash dump core after I interrupt username completion or + `~user' tilde expansion on a machine running NIS? + +This is a famous and long-standing bug in the SunOS YP (sorry, NIS) +client library, which is part of libc. + +The YP library code keeps static state -- a pointer into the data +returned from the server. When YP initializes itself (setpwent), +it looks at this pointer and calls free on it if it's non-null. +So far, so good. + +If one of the YP functions is interrupted during getpwent (the +exact function is interpretwithsave()), and returns NULL, the +pointer is freed without being reset to NULL, and the function +returns. The next time getpwent is called, it sees that this +pointer is non-null, calls free, and the bash free() blows up +because it's being asked to free freed memory. + +The traditional Unix mallocs allow memory to be freed multiple +times; that's probably why this has never been fixed. You can +run configure with the `--without-gnu-malloc' option to use +the C library malloc and avoid the problem. + +F4) I'm running SVR4.2. Why is the line erased every time I type `@'? + +The `@' character is the default `line kill' character in most +versions of System V, including SVR4.2. You can change this +character to whatever you want using `stty'. For example, to +change the line kill character to control-u, type + + stty kill ^U + +where the `^' and `U' can be two separate characters. + +F5) Why does bash report syntax errors when my C News scripts use a + redirection before a subshell command? + +The actual command in question is something like + + < file ( command ) + +According to the grammar given in the POSIX.2 standard, this construct +is, in fact, a syntax error. Redirections may only precede `simple +commands'. A subshell construct such as the above is one of the shell's +`compound commands'. A redirection may only follow a compound command. + +This affects the mechanical transformation of commands that use `cat' +to pipe a file into a command (a favorite Useless-Use-Of-Cat topic on +comp.unix.shell). While most commands of the form + + cat file | command + +can be converted to `< file command', shell control structures such as +loops and subshells require `command < file'. + +The file CWRU/sh-redir-hack in the bash-2.05a distribution is an +(unofficial) patch to parse.y that will modify the grammar to +support this construct. It will not apply with `patch'; you must +modify parse.y by hand. Note that if you apply this, you must +recompile with -DREDIRECTION_HACK. This introduces a large +number of reduce/reduce conflicts into the shell grammar. + +F6) Why can't I use vi-mode editing on Red Hat Linux 6.1? + +The short answer is that Red Hat screwed up. + +The long answer is that they shipped an /etc/inputrc that only works +for emacs mode editing, and then screwed all the vi users by setting +INPUTRC to /etc/inputrc in /etc/profile. + +The short fix is to do one of the following: remove or rename +/etc/inputrc, set INPUTRC=~/.inputrc in ~/.bashrc (or .bash_profile, +but make sure you export it if you do), remove the assignment to +INPUTRC from /etc/profile, add + + set keymap emacs + +to the beginning of /etc/inputrc, or bracket the key bindings in +/etc/inputrc with these lines + + $if mode=emacs + [...] + $endif + +F7) Why do bash-2.05a and bash-2.05b fail to compile `printf.def' on + HP/UX 11.x? + +HP/UX's support for long double is imperfect at best. + +GCC will support it without problems, but the HP C library functions +like strtold(3) and printf(3) don't actually work with long doubles. +HP implemented a `long_double' type as a 4-element array of 32-bit +ints, and that is what the library functions use. The ANSI C +`long double' type is a 128-bit floating point scalar. + +The easiest fix, until HP fixes things up, is to edit the generated +config.h and #undef the HAVE_LONG_DOUBLE line. After doing that, +the compilation should complete successfully. + +Section G: How can I get bash to do certain common things? + +G1) How can I get bash to read and display eight-bit characters? + +This is a process requiring several steps. + +First, you must ensure that the `physical' data path is a full eight +bits. For xterms, for example, the `vt100' resources `eightBitInput' +and `eightBitOutput' should be set to `true'. + +Once you have set up an eight-bit path, you must tell the kernel and +tty driver to leave the eighth bit of characters alone when processing +keyboard input. Use `stty' to do this: + + stty cs8 -istrip -parenb + +For old BSD-style systems, you can use + + stty pass8 + +You may also need + + stty even odd + +Finally, you need to tell readline that you will be inputting and +displaying eight-bit characters. You use readline variables to do +this. These variables can be set in your .inputrc or using the bash +`bind' builtin. Here's an example using `bind': + + bash$ bind 'set convert-meta off' + bash$ bind 'set meta-flag on' + bash$ bind 'set output-meta on' + +The `set' commands between the single quotes may also be placed +in ~/.inputrc. + +G2) How do I write a function `x' to replace builtin command `x', but + still invoke the command from within the function? + +This is why the `command' and `builtin' builtins exist. The +`command' builtin executes the command supplied as its first +argument, skipping over any function defined with that name. The +`builtin' builtin executes the builtin command given as its first +argument directly. + +For example, to write a function to replace `cd' that writes the +hostname and current directory to an xterm title bar, use +something like the following: + + cd() + { + builtin cd "$@" && xtitle "$HOST: $PWD" + } + +This could also be written using `command' instead of `builtin'; +the version above is marginally more efficient. + +G3) How can I find the value of a shell variable whose name is the value + of another shell variable? + +Versions of Bash newer than Bash-2.0 support this directly. You can use + + ${!var} + +For example, the following sequence of commands will echo `z': + + var1=var2 + var2=z + echo ${!var1} + +For sh compatibility, use the `eval' builtin. The important +thing to remember is that `eval' expands the arguments you give +it again, so you need to quote the parts of the arguments that +you want `eval' to act on. + +For example, this expression prints the value of the last positional +parameter: + + eval echo \"\$\{$#\}\" + +The expansion of the quoted portions of this expression will be +deferred until `eval' runs, while the `$#' will be expanded +before `eval' is executed. In versions of bash later than bash-2.0, + + echo ${!#} + +does the same thing. + +This is not the same thing as ksh93 `nameref' variables, though the syntax +is similar. I may add namerefs in a future bash version. + +G4) How can I make the bash `time' reserved word print timing output that + looks like the output from my system's /usr/bin/time? + +The bash command timing code looks for a variable `TIMEFORMAT' and +uses its value as a format string to decide how to display the +timing statistics. + +The value of TIMEFORMAT is a string with `%' escapes expanded in a +fashion similar in spirit to printf(3). The manual page explains +the meanings of the escape sequences in the format string. + +If TIMEFORMAT is not set, bash acts as if the following assignment had +been performed: + + TIMEFORMAT=$'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS' + +The POSIX.2 default time format (used by `time -p command') is + + TIMEFORMAT=$'real %2R\nuser %2U\nsys %2S' + +The BSD /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\t%1R real\t%1U user\t%1S sys' + +The System V /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\nreal\t%1R\nuser\t%1U\nsys\t%1S' + +The ksh format can be emulated with: + + TIMEFORMAT=$'\nreal\t%2lR\nuser\t%2lU\nsys\t%2lS' + +G5) How do I get the current directory into my prompt? + +Bash provides a number of backslash-escape sequences which are expanded +when the prompt string (PS1 or PS2) is displayed. The full list is in +the manual page. + +The \w expansion gives the full pathname of the current directory, with +a tilde (`~') substituted for the current value of $HOME. The \W +expansion gives the basename of the current directory. To put the full +pathname of the current directory into the path without any tilde +subsitution, use $PWD. Here are some examples: + + PS1='\w$ ' # current directory with tilde + PS1='\W$ ' # basename of current directory + PS1='$PWD$ ' # full pathname of current directory + +The single quotes are important in the final example to prevent $PWD from +being expanded when the assignment to PS1 is performed. + +G6) How can I rename "*.foo" to "*.bar"? + +Use the pattern removal functionality described in D3. The following `for' +loop will do the trick: + + for f in *.foo; do + mv $f ${f%foo}bar + done + +G7) How can I translate a filename from uppercase to lowercase? + +The script examples/functions/lowercase, originally written by John DuBois, +will do the trick. The converse is left as an exercise. + +G8) How can I write a filename expansion (globbing) pattern that will match + all files in the current directory except "." and ".."? + +You must have set the `extglob' shell option using `shopt -s extglob' to use +this: + + echo .!(.|) * + +A solution that works without extended globbing is given in the Unix Shell +FAQ, posted periodically to comp.unix.shell. + +Section H: Where do I go from here? + +H1) How do I report bugs in bash, and where should I look for fixes and + advice? + +Use the `bashbug' script to report bugs. It is built and +installed at the same time as bash. It provides a standard +template for reporting a problem and automatically includes +information about your configuration and build environment. + +`bashbug' sends its reports to bug-bash@gnu.org, which +is a large mailing list gatewayed to the usenet newsgroup gnu.bash.bug. + +Bug fixes, answers to questions, and announcements of new releases +are all posted to gnu.bash.bug. Discussions concerning bash features +and problems also take place there. + +To reach the bash maintainers directly, send mail to +bash-maintainers@gnu.org. + +H2) What kind of bash documentation is there? + +First, look in the doc directory in the bash distribution. It should +contain at least the following files: + +bash.1 an extensive, thorough Unix-style manual page +builtins.1 a manual page covering just bash builtin commands +bashref.texi a reference manual in GNU tex`info format +bashref.info an info version of the reference manual +FAQ this file +article.ms text of an article written for The Linux Journal +readline.3 a man page describing readline + +Postscript, HTML, and ASCII files created from the above source are +available in the documentation distribution. + +There is additional documentation available for anonymous FTP from host +ftp.cwru.edu in the `pub/bash' directory. + +Cameron Newham and Bill Rosenblatt have written a book on bash, published +by O'Reilly and Associates. The book is based on Bill Rosenblatt's Korn +Shell book. The title is ``Learning the Bash Shell'', and the ISBN number +is 1-56592-147-X. Look for it in fine bookstores near you. This book +covers bash-1.14, but has an appendix describing some of the new features +in bash-2.0. + +A second edition of this book is available, published in January, 1998. +The ISBN number is 1-56592-347-2. Look for it in the same fine bookstores +or on the web. + +The GNU Bash Reference Manual has been published as a printed book by +Network Theory Ltd (Paperback, ISBN: 0-9541617-7-7, Feb 2003). It covers +bash-2.0 and is available from most online bookstores (see +http://www.network-theory.co.uk/bash/manual/ for details). The publisher +will donate $1 to the Free Software Foundation for each copy sold. + +H3) What's coming in future versions? + +These are features I hope to include in a future version of bash. + +a better bash debugger (a minimally-tested version is included with bash-2.05b) +associative arrays +co-processes, but with a new-style syntax that looks like function declaration + +H4) What's on the bash `wish list' for future versions? + +These are features that may or may not appear in a future version of bash. + +breaking some of the shell functionality into embeddable libraries +a module system like zsh's, using dynamic loading like builtins +better internationalization using GNU `gettext' +date-stamped command history +a bash programmer's guide with a chapter on creating loadable builtins +a better loadable interface to perl with access to the shell builtins and + variables (contributions gratefully accepted) +ksh93-like `nameref' variables +ksh93-like `+=' variable assignment operator +ksh93-like `xx.yy' variables (including some of the .sh.* variables) and + associated disipline functions +Some of the new ksh93 pattern matching operators, like backreferencing + +H5) When will the next release appear? + +The next version will appear sometime in 2002.

It is an implementation of +the Posix 1003.2 shell standard, and resembles the Korn and System V +shells. + +Bash contains a number of enhancements over those shells, both +for interactive use and shell programming. Features geared +toward interactive use include command line editing, command +history, job control, aliases, and prompt expansion. Programming +features include additional variable expansions, shell +arithmetic, and a number of variables and options to control +shell behavior. + +Bash was originally written by Brian Fox of the Free Software +Foundation. The current developer and maintainer is Chet Ramey +of Case Western Reserve University. + +A2) What's the latest version? + +The latest version is 2.05b, first made available on Wednesday, 17 +July, 2002. + +A3) Where can I get it? + +Bash is the GNU project's shell, and so is available from the +master GNU archive site, ftp.gnu.org, and its mirrors. The +latest version is also available for FTP from ftp.cwru.edu. +The following URLs tell how to get version 2.05b: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-2.05b.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-2.05b.tar.gz + +Formatted versions of the documentation are available with the URLs: + +ftp://ftp.gnu.org/pub/gnu/bash/bash-doc-2.05b.tar.gz +ftp://ftp.cwru.edu/pub/bash/bash-doc-2.05b.tar.gz + +A4) On what machines will bash run? + +Bash has been ported to nearly every version of UNIX. All you +should have to do to build it on a machine for which a port +exists is to type `configure' and then `make'. The build process +will attempt to discover the version of UNIX you have and tailor +itself accordingly, using a script created by GNU autoconf. + +More information appears in the file `INSTALL' in the distribution. + +The Bash web page (http://cnswww.cns.cwru.edu/~chet/bash/bashtop.html) +explains how to obtain binary versions of bash for most of the major +commercial Unix systems. + +A5) Will bash run on operating systems other than Unix? + +Configuration specifics for Unix-like systems such as QNX and +LynxOS are included in the distribution. Bash-2.05 and later +versions should compile and run on Minix 2.0 (patches were +contributed), but I don't believe anyone has built bash-2.x on +earlier Minix versions yet. + +Bash has been ported to versions of Windows implementing the Win32 +programming interface. This includes Windows 95 and Windows NT. +The port was done by Cygnus Solutions as part of their CYGWIN +project. For more information about the project, look at the URLs + +http://www.cygwin.com/ +http://sourceware.cygnus.com/cygwin + +Cygnus originally ported bash-1.14.7, and that port was part of their +early GNU-Win32 (the original name) releases. Cygnus has also done a +port of bash-2.05 to the CYGWIN environment, and it is available as +part of their current release. + +Bash-2.05b should require no local Cygnus changes to build and run under +CYGWIN. + +The Cygnus port works only on Intel machines. There is a port of bash +(I don't know which version) to the alpha/NT environment available from + +ftp://ftp.gnustep.org//pub/win32/bash-alpha-nt-1.01.tar.gz + +DJ Delorie has a port of bash-2.x which runs under MS-DOS, as part +of the DJGPP project. For more information on the project, see + +http://www.delorie.com/djgpp/ + +I have been told that the original DJGPP port was done by Daisuke Aoyama. + +Mark Elbrecht has sent me notice that bash-2.04 +is available for DJGPP V2.

Beware. + +I have received word that Bash (I'm not sure which version, but I +believe that it's at least bash-2.02.1) is the standard shell on +BeOS. + +A6) How can I build bash with gcc? + +Bash configures to use gcc by default if it is available. Read the +file INSTALL in the distribution for more information. + +A7) How can I make bash my login shell? + +Some machines let you use `chsh' to change your login shell. Other +systems use `passwd -s' or `passwd -e'. If one of these works for +you, that's all you need. Note that many systems require the full +pathname to a shell to appear in /etc/shells before you can make it +your login shell. For this, you may need the assistance of your +friendly local system administrator. + +If you cannot do this, you can still use bash as your login shell, but +you need to perform some tricks. The basic idea is to add a command +to your login shell's startup file to replace your login shell with +bash. + +For example, if your login shell is csh or tcsh, and you have installed +bash in /usr/gnu/bin/bash, add the following line to ~/.login: + + if ( -f /usr/gnu/bin/bash ) exec /usr/gnu/bin/bash --login + +(the `--login' tells bash that it is a login shell). + +It's not a good idea to put this command into ~/.cshrc, because every +csh you run without the `-f' option, even ones started to run csh scripts, +reads that file. If you must put the command in ~/.cshrc, use something +like + + if ( $?prompt ) exec /usr/gnu/bin/bash --login + +to ensure that bash is exec'd only when the csh is interactive. + +If your login shell is sh or ksh, you have to do two things. + +First, create an empty file in your home directory named `.bash_profile'. +The existence of this file will prevent the exec'd bash from trying to +read ~/.profile, and re-execing itself over and over again. ~/.bash_profile +is the first file bash tries to read initialization commands from when +it is invoked as a login shell. + +Next, add a line similar to the above to ~/.profile: + + [ -f /usr/gnu/bin/bash ] && [ -x /usr/gnu/bin/bash ] && \ + exec /usr/gnu/bin/bash --login + +This will cause login shells to replace themselves with bash running as +a login shell. Once you have this working, you can copy your initialization +code from ~/.profile to ~/.bash_profile. + +I have received word that the recipe supplied above is insufficient for +machines running CDE. CDE has a maze of twisty little startup files, all +slightly different. + +If you cannot change your login shell in the password file to bash, you +will have to (apparently) live with CDE using the shell in the password +file to run its startup scripts. If you have changed your shell to bash, +there is code in the CDE startup files (on Solaris, at least) that attempts +to do the right thing. It is, however, often broken, and may require that +you use the $BASH_ENV trick described below. + +`dtterm' claims to use $SHELL as the default program to start, so if you +can change $SHELL in the CDE startup files, you should be able to use bash +in your terminal windows. + +Setting DTSOURCEPROFILE in ~/.dtprofile will cause the `Xsession' program +to read your login shell's startup files. You may be able to use bash for +the rest of the CDE programs by setting SHELL to bash in ~/.dtprofile as +well, but I have not tried this. + +You can use the above `exec' recipe to start bash when not logging in with +CDE by testing the value of the DT variable: + + if [ -n "$DT" ]; then + [ -f /usr/gnu/bin/bash ] && exec /usr/gnu/bin/bash --login + fi + +If CDE starts its shells non-interactively during login, the login shell +startup files (~/.profile, ~/.bash_profile) will not be sourced at login. +To get around this problem, append a line similar to the following to your +~/.dtprofile: + + BASH_ENV=${HOME}/.bash_profile ; export BASH_ENV + +and add the following line to the beginning of ~/.bash_profile: + + unset BASH_ENV + +A8) I just changed my login shell to bash, and now I can't FTP into my + machine. Why not? + +You must add the full pathname to bash to the file /etc/shells. As +noted in the answer to the previous question, many systems require +this before you can make bash your login shell. + +Most versions of ftpd use this file to prohibit `special' users +such as `uucp' and `news' from using FTP. + +A9) What's the `POSIX 1003.2 standard'? + +POSIX is a name originally coined by Richard Stallman for a +family of open system standards based on UNIX. There are a +number of aspects of UNIX under consideration for +standardization, from the basic system services at the system +call and C library level to applications and tools to system +administration and management. Each area of standardization is +assigned to a working group in the 1003 series. + +The POSIX Shell and Utilities standard has been developed by IEEE +Working Group 1003.2 (POSIX.2). It concentrates on the command +interpreter interface and utility programs commonly executed from +the command line or by other programs. An initial version of the +standard has been approved and published by the IEEE, and work is +currently underway to update it. + +Bash is concerned with the aspects of the shell's behavior +defined by POSIX.2. The shell command language has of course +been standardized, including the basic flow control and program +execution constructs, I/O redirection and pipelining, argument +handling, variable expansion, and quoting. + +The `special' builtins, which must be implemented as part of the +shell to provide the desired functionality, are specified as +being part of the shell; examples of these are `eval' and +`export'. Other utilities appear in the sections of POSIX.2 not +devoted to the shell which are commonly (and in some cases must +be) implemented as builtin commands, such as `read' and `test'. +POSIX.2 also specifies aspects of the shell's interactive +behavior as part of the UPE, including job control and command +line editing. Only vi-style line editing commands have been +standardized; emacs editing commands were left out due to +objections. + +The Open Group has made an older version of its Single Unix +Specification (version 2), which is very similar to POSIX.2, +available on the web at + +http://www.opengroup.org/onlinepubs/007908799/ + +The Single Unix Specification, version 3, is available on the web at + +http://www.opengroup.org/onlinepubs/007904975/ + +A10) What is the bash `posix mode'? + +Although bash is an implementation of the POSIX.2 shell +specification, there are areas where the bash default behavior +differs from that spec. The bash `posix mode' changes the bash +behavior in these areas so that it obeys the spec more closely. + +Posix mode is entered by starting bash with the --posix or +'-o posix' option or executing `set -o posix' after bash is running. + +The specific aspects of bash which change when posix mode is +active are listed in the file POSIX in the bash distribution. +They are also listed in a section in the Bash Reference Manual +(from which that file is generated). + +Section B: The latest version + +B1) What's new in version 2.05b? + +The raison d'etre for bash-2.05b is to make a second intermediate +release containing the first of the new features to be available +in bash-3.0 and get feedback on those features before proceeding. +The major new feature is multibyte character support in both Bash +and Readline. + +Bash-2.05b contains the following new features (see the manual page for +complete descriptions and the CHANGES and NEWS files in the bash-2.05b +distribution): + +o support for multibyte characters has been added to both bash and readline + +o the DEBUG trap is now run *before* simple commands, ((...)) commands, + [[...]] conditional commands, and for ((...)) loops + +o the shell now performs arithmetic in the largest integer size the machine + supports (intmax_t) + +o there is a new \D{...} prompt expansion; passes the `...' to strftime(3) + and inserts the result into the expanded prompt + +o there is a new `here-string' redirection operator: <<< word + +o when displaying variables, function attributes and definitions are shown + separately, allowing them to be re-used as input (attempting to re-use + the old output would result in syntax errors). + +o `read' has a new `-u fd' option to read from a specified file descriptor + +o the bash debugger in examples/bashdb has been modified to work with the + new DEBUG trap semantics, the command set has been made more gdb-like, + and the changes to $LINENO make debugging functions work better + +o the expansion of $LINENO inside a shell function is only relative to the + function start if the shell is interactive -- if the shell is running a + script, $LINENO expands to the line number in the script.

+ +D1) Why does bash run a different version of `command' than + `which command' says it will? + +On many systems, `which' is actually a csh script that assumes +you're running csh. In tcsh, `which' and its cousin `where' +are builtins. On other Unix systems, `which' is a perl script +that uses the PATH environment variable. + +The csh script version reads the csh startup files from your +home directory and uses those to determine which `command' will +be invoked. Since bash doesn't use any of those startup files, +there's a good chance that your bash environment differs from +your csh environment. The bash `type' builtin does everything +`which' does, and will report correct results for the running +shell. If you're really wedded to the name `which', try adding +the following function definition to your .bashrc: + + which() + { + builtin type "$@" + } + +If you're moving from tcsh and would like to bring `where' along +as well, use this function: + + where() + { + builtin type -a "$@" + } + +D2) Why doesn't bash treat brace expansions exactly like csh? + +The only difference between bash and csh brace expansion is that +bash requires a brace expression to contain at least one unquoted +comma if it is to be expanded. Any brace-surrounded word not +containing an unquoted comma is left unchanged by the brace +expansion code. This affords the greatest degree of sh +compatibility. + +Bash, ksh, zsh, and pd-ksh all implement brace expansion this way. + +D3) Why doesn't bash have csh variable modifiers? + +Posix has specified a more powerful, albeit somewhat more cryptic, +mechanism cribbed from ksh, and bash implements it. + +${parameter%word} + Remove smallest suffix pattern. The WORD is expanded to produce + a pattern.

We have provided +a shell script which does most of the work of conversion for you; +this script can be found in ./examples/misc/aliasconv.sh. Here is +how you use it: + +Start csh in the normal way for you. (e.g., `csh') + +Pipe the output of `alias' through `aliasconv.sh', saving the +results into `bash_aliases': + + alias | bash aliasconv.sh >bash_aliases + +Edit `bash_aliases', carefully reading through any created +functions. You will need to change the names of some csh specific +variables to the bash equivalents. The script converts $cwd to +$PWD, $term to $TERM, $home to $HOME, $user to $USER, and $prompt +to $PS1. You may also have to add quotes to avoid unwanted +expansion. + +For example, the csh alias: + + alias cd 'cd \!*; echo $cwd' + +is converted to the bash function: + + cd () { command cd "$@"; echo $PWD ; } + +The only thing that needs to be done is to quote $PWD: + + cd () { command cd "$@"; echo "$PWD" ; } + +Merge the edited file into your ~/.bashrc. + +There is an additional, more ambitious, script in +examples/misc/cshtobash that attempts to convert your entire csh +environment to its bash equivalent. This script can be run as +simply `cshtobash' to convert your normal interactive +environment, or as `cshtobash ~/.login' to convert your login +environment. + +D5) How can I pipe standard output and standard error from one command to + another, like csh does with `|&'? + +Use + command 2>&1 | command2 + +The key is to remember that piping is performed before redirection, so +file descriptor 1 points to the pipe when it is duplicated onto file +descriptor 2. + +D6) Now that I've converted from ksh to bash, are there equivalents to + ksh features like autoloaded functions and the `whence' command? + +There are features in ksh-88 and ksh-93 that do not have direct bash +equivalents. Most, however, can be emulated with very little trouble. + +ksh-88 feature Bash equivalent +-------------- --------------- +compiled-in aliases set up aliases in .bashrc; some ksh aliases are + bash builtins (hash, history, type) +coprocesses named pipe pairs (one for read, one for write) +typeset +f declare -F +cd, print, whence function substitutes in examples/functions/kshenv +autoloaded functions examples/functions/autoload is the same as typeset -fu +read var?prompt read -p prompt var + +ksh-93 feature Bash equivalent +-------------- --------------- +sleep, getconf Bash has loadable versions in examples/loadables +${.sh.version} $BASH_VERSION +print -f printf +hist alias hist=fc +$HISTEDIT $FCEDIT + +Section E: How can I get bash to do certain things, and why does bash do + things the way it does? + +E1) Why is the bash builtin `test' slightly different from /bin/test? + +The specific example used here is [ ! x -o x ], which is false. + +Bash's builtin `test' implements the Posix.2 spec, which can be +summarized as follows (the wording is due to David Korn): + +Here is the set of rules for processing test arguments. + + 0 Args: False + 1 Arg: True iff argument is not null. + 2 Args: If first arg is !, True iff second argument is null. + If first argument is unary, then true if unary test is true + Otherwise error. + 3 Args: If second argument is a binary operator, do binary test of $1 $3 + If first argument is !, negate two argument test of $2 $3 + If first argument is `(' and third argument is `)', do the + one-argument test of the second argument. + Otherwise error. + 4 Args: If first argument is !, negate three argument test of $2 $3 $4. + Otherwise unspecified + 5 or more Args: unspecified. (Historical shells would use their + current algorithm). + +The operators -a and -o are considered binary operators for the purpose +of the 3 Arg case. + +As you can see, the test becomes (not (x or x)), which is false. + +E2) Why does bash sometimes say `Broken pipe'? + +If a sequence of commands appears in a pipeline, and one of the +reading commands finishes before the writer has finished, the +writer receives a SIGPIPE signal. Many other shells special-case +SIGPIPE as an exit status in the pipeline and do not report it. +For example, in: + + ps -aux | head + +`head' can finish before `ps' writes all of its output, and ps +will try to write on a pipe without a reader. In that case, bash +will print `Broken pipe' to stderr when ps is killed by a +SIGPIPE. + +You can build a version of bash that will not report SIGPIPE errors +by uncommenting the definition of DONT_REPORT_SIGPIPE in the file +config-top.h. + +E3) When I have terminal escape sequences in my prompt, why does bash + wrap lines at the wrong column? + +Readline, the line editing library that bash uses, does not know +that the terminal escape sequences do not take up space on the +screen. The redisplay code assumes, unless told otherwise, that +each character in the prompt is a `printable' character that +takes up one character position on the screen. + +You can use the bash prompt expansion facility (see the PROMPTING +section in the manual page) to tell readline that sequences of +characters in the prompt strings take up no screen space. + +Use the \[ escape to begin a sequence of non-printing characters, +and the \] escape to signal the end of such a sequence. + +E4) If I pipe the output of a command into `read variable', why doesn't + the output show up in $variable when the read command finishes? + +This has to do with the parent-child relationship between Unix +processes. It affects all commands run in pipelines, not just +simple calls to `read'. For example, piping a command's output +into a `while' loop that repeatedly calls `read' will result in +the same behavior. + +Each element of a pipeline runs in a separate process, a child of +the shell running the pipeline. A subprocess cannot affect its +parent's environment. When the `read' command sets the variable +to the input, that variable is set only in the subshell, not the +parent shell. When the subshell exits, the value of the variable +is lost. + +Many pipelines that end with `read variable' can be converted +into command substitutions, which will capture the output of +a specified command. The output can then be assigned to a +variable: + + grep ^gnu /usr/lib/news/active | wc -l | read ngroup + +can be converted into + + ngroup=$(grep ^gnu /usr/lib/news/active | wc -l) + +This does not, unfortunately, work to split the text among +multiple variables, as read does when given multiple variable +arguments. If you need to do this, you can either use the +command substitution above to read the output into a variable +and chop up the variable using the bash pattern removal +expansion operators or use some variant of the following +approach. + +Say /usr/local/bin/ipaddr is the following shell script: + +#! /bin/sh +host `hostname` | awk '/address/ {print $NF}' + +Instead of using + + /usr/local/bin/ipaddr | read A B C D + +to break the local machine's IP address into separate octets, use + + OIFS="$IFS" + IFS=. + set -- $(/usr/local/bin/ipaddr) + IFS="$OIFS" + A="$1" B="$2" C="$3" D="$4" + +Beware, however, that this will change the shell's positional +parameters. If you need them, you should save them before doing +this. + +This is the general approach -- in most cases you will not need to +set $IFS to a different value. + +Some other user-supplied alternatives include: + +read A B C D << HERE + $(IFS=.; echo $(/usr/local/bin/ipaddr)) +HERE + +and, where process substitution is available, + +read A B C D < <(IFS=.; echo $(/usr/local/bin/ipaddr)) + +E5) I have a bunch of shell scripts that use backslash-escaped characters + in arguments to `echo'. Bash doesn't interpret these characters. Why + not, and how can I make it understand them? + +This is the behavior of echo on most Unix System V machines. + +The bash builtin `echo' is modeled after the 9th Edition +Research Unix version of `echo'. It does not interpret +backslash-escaped characters in its argument strings by default; +it requires the use of the -e option to enable the +interpretation. The System V echo provides no way to disable the +special characters; the bash echo has a -E option to disable +them. + +There is a configuration option that will make bash behave like +the System V echo and interpret things like `\t' by default. Run +configure with the --enable-xpg-echo-default option to turn this +on. Be aware that this will cause some of the tests run when you +type `make tests' to fail. + +There is a shell option, `xpg_echo', settable with `shopt', that will +change the behavior of echo at runtime. Enabling this option turns +on expansion of backslash-escape sequences. + +E6) Why doesn't a while or for loop get suspended when I type ^Z? + +This is a consequence of how job control works on Unix. The only +thing that can be suspended is the process group. This is a single +command or pipeline of commands that the shell forks and executes. + +When you run a while or for loop, the only thing that the shell forks +and executes are any commands in the while loop test and commands in +the loop bodies. These, therefore, are the only things that can be +suspended when you type ^Z. + +If you want to be able to stop the entire loop, you need to put it +within parentheses, which will force the loop into a subshell that +may be stopped (and subsequently restarted) as a single unit. + +E7) What about empty for loops in Makefiles? + +It's fairly common to see constructs like this in automatically-generated +Makefiles: + +SUBDIRS = @SUBDIRS@ + + ... + +subdirs-clean: + for d in ${SUBDIRS}; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +When SUBDIRS is empty, this results in a command like this being passed to +bash: + + for d in ; do + ( cd $d && ${MAKE} ${MFLAGS} clean ) + done + +In versions of bash before bash-2.05a, this was a syntax error. If the +reserved word `in' was present, a word must follow it before the semicolon +or newline. The language in the manual page referring to the list of words +being empty referred to the list after it is expanded. These versions of +bash required that there be at least one word following the `in' when the +construct was parsed. + +The idiomatic Makefile solution is something like: + +SUBDIRS = @SUBDIRS@ + +subdirs-clean: + subdirs=$SUBDIRS ; for d in $$subdirs; do \ + ( cd $$d && ${MAKE} ${MFLAGS} clean ) \ + done + +The latest drafts of the updated POSIX standard have changed this: the +word list is no longer required. Bash versions 2.05a and later accept +the new syntax. + +E8) Why does the arithmetic evaluation code complain about `08'? + +The bash arithmetic evaluation code (used for `let', $(()), (()), and in +other places), interprets a leading `0' in numeric constants as denoting +an octal number, and a leading `0x' as denoting hexadecimal. This is +in accordance with the POSIX.2 spec, section 2.9.2.1, which states that +arithmetic constants should be handled as signed long integers as defined +by the ANSI/ISO C standard. + +The POSIX.2 interpretation committee has confirmed this: + +http://www.pasc.org/interps/unofficial/db/p1003.2/pasc-1003.2-173.html + +E9) Why does the pattern matching expression [A-Z]* match files beginning + with every letter except `z'? + +Bash-2.03, Bash-2.05 and later versions honor the current locale setting +when processing ranges within pattern matching bracket expressions ([A-Z]). +This is what POSIX.2 and SUSv3/XPG6 specify. + +The behavior of the matcher in bash-2.05 and later versions depends on the +current LC_COLLATE setting. Setting this variable to `C' or `POSIX' will +result in the traditional behavior ([A-Z] matches all uppercase ASCII +characters). Many other locales, including the en_US locale (the default +on many US versions of Linux) collate the upper and lower case letters like +this: + + AaBb...Zz + +which means that [A-Z] matches every letter except `z'. Others collate like + + aAbBcC...zZ + +which means that [A-Z] matches every letter except `a'. + +The portable way to specify upper case letters is [:upper:] instead of +A-Z; lower case may be specified as [:lower:] instead of a-z. + +Look at the manual pages for setlocale(3), strcoll(3), and, if it is +present, locale(1). If you have locale(1), you can use it to find +your current locale information even if you do not have any of the +LC_ variables set. + +My advice is to put + + export LC_COLLATE=C + +into /etc/profile and inspect any shell scripts run from cron for +constructs like [A-Z]. This will prevent things like + + rm [A-Z]* + +from removing every file in the current directory except those beginning +with `z' and still allow individual users to change the collation order. +Users may put the above command into their own profiles as well, of course. + +E10) Why does `cd //' leave $PWD as `//'? + +POSIX.2, in its description of `cd', says that *three* or more leading +slashes may be replaced with a single slash when canonicalizing the +current working directory. + +This is, I presume, for historical compatibility. Certain versions of +Unix, and early network file systems, used paths of the form +//hostname/path to access `path' on server `hostname'. + +E11) If I resize my xterm while another program is running, why doesn't bash + notice the change? + +This is another issue that deals with job control. + +The kernel maintains a notion of a current terminal process group. Members +of this process group (processes whose process group ID is equal to the +current terminal process group ID) receive terminal-generated signals like +SIGWINCH. (For more details, see the JOB CONTROL section of the bash +man page.) + +If a terminal is resized, the kernel sends SIGWINCH to each member of +the terminal's current process group (the `foreground' process group). + +When bash is running with job control enabled, each pipeline (which may be +a single command) is run in its own process group, different from bash's +process group. This foreground process group receives the SIGWINCH; bash +does not. Bash has no way of knowing that the terminal has been resized. + +There is a `checkwinsize' option, settable with the `shopt' builtin, that +will cause bash to check the window size and adjust its idea of the +terminal's dimensions each time a process stops or exits and returns control +of the terminal to bash. Enable it with `shopt -s checkwinsize'. + +Section F: Things to watch out for on certain Unix versions + +F1) Why can't I use command line editing in my `cmdtool'? + +The problem is `cmdtool' and bash fighting over the input. When +scrolling is enabled in a cmdtool window, cmdtool puts the tty in +`raw mode' to permit command-line editing using the mouse for +applications that cannot do it themselves. As a result, bash and +cmdtool each try to read keyboard input immediately, with neither +getting enough of it to be useful. + +This mode also causes cmdtool to not implement many of the +terminal functions and control sequences appearing in the +`sun-cmd' termcap entry. For a more complete explanation, see +that file examples/suncmd.termcap in the bash distribution. + +`xterm' is a better choice, and gets along with bash much more +smoothly. + +If you must use cmdtool, you can use the termcap description in +examples/suncmd.termcap. Set the TERMCAP variable to the terminal +description contained in that file, i.e. + +TERMCAP='Mu|sun-cmd:am:bs:km:pt:li#34:co#80:cl=^L:ce=\E[K:cd=\E[J:rs=\E[s:' + +Then export TERMCAP and start a new cmdtool window from that shell. +The bash command-line editing should behave better in the new +cmdtool. If this works, you can put the assignment to TERMCAP +in your bashrc file. + +F2) I built bash on Solaris 2. Why do globbing expansions and filename + completion chop off the first few characters of each filename? + +This is the consequence of building bash on SunOS 5 and linking +with the libraries in /usr/ucblib, but using the definitions +and structures from files in /usr/include. + +The actual conflict is between the dirent structure in +/usr/include/dirent.h and the struct returned by the version of +`readdir' in libucb.a (a 4.3-BSD style `struct direct'). + +Make sure you've got /usr/ccs/bin ahead of /usr/ucb in your $PATH +when configuring and building bash. This will ensure that you +use /usr/ccs/bin/cc or acc instead of /usr/ucb/cc and that you +link with libc before libucb. + +If you have installed the Sun C compiler, you may also need to +put /usr/ccs/bin and /opt/SUNWspro/bin into your $PATH before +/usr/ucb. + +F3) Why does bash dump core after I interrupt username completion or + `~user' tilde expansion on a machine running NIS? + +This is a famous and long-standing bug in the SunOS YP (sorry, NIS) +client library, which is part of libc. + +The YP library code keeps static state -- a pointer into the data +returned from the server. When YP initializes itself (setpwent), +it looks at this pointer and calls free on it if it's non-null. +So far, so good. + +If one of the YP functions is interrupted during getpwent (the +exact function is interpretwithsave()), and returns NULL, the +pointer is freed without being reset to NULL, and the function +returns. The next time getpwent is called, it sees that this +pointer is non-null, calls free, and the bash free() blows up +because it's being asked to free freed memory. + +The traditional Unix mallocs allow memory to be freed multiple +times; that's probably why this has never been fixed. You can +run configure with the `--without-gnu-malloc' option to use +the C library malloc and avoid the problem. + +F4) I'm running SVR4.2. Why is the line erased every time I type `@'? + +The `@' character is the default `line kill' character in most +versions of System V, including SVR4.2. You can change this +character to whatever you want using `stty'. For example, to +change the line kill character to control-u, type + + stty kill ^U + +where the `^' and `U' can be two separate characters. + +F5) Why does bash report syntax errors when my C News scripts use a + redirection before a subshell command? + +The actual command in question is something like + + < file ( command ) + +According to the grammar given in the POSIX.2 standard, this construct +is, in fact, a syntax error. Redirections may only precede `simple +commands'. A subshell construct such as the above is one of the shell's +`compound commands'. A redirection may only follow a compound command. + +This affects the mechanical transformation of commands that use `cat' +to pipe a file into a command (a favorite Useless-Use-Of-Cat topic on +comp.unix.shell). While most commands of the form + + cat file | command + +can be converted to `< file command', shell control structures such as +loops and subshells require `command < file'. + +The file CWRU/sh-redir-hack in the bash-2.05a distribution is an +(unofficial) patch to parse.y that will modify the grammar to +support this construct. It will not apply with `patch'; you must +modify parse.y by hand. Note that if you apply this, you must +recompile with -DREDIRECTION_HACK. This introduces a large +number of reduce/reduce conflicts into the shell grammar. + +F6) Why can't I use vi-mode editing on Red Hat Linux 6.1? + +The short answer is that Red Hat screwed up. + +The long answer is that they shipped an /etc/inputrc that only works +for emacs mode editing, and then screwed all the vi users by setting +INPUTRC to /etc/inputrc in /etc/profile. + +The short fix is to do one of the following: remove or rename +/etc/inputrc, set INPUTRC=~/.inputrc in ~/.bashrc (or .bash_profile, +but make sure you export it if you do), remove the assignment to +INPUTRC from /etc/profile, add + + set keymap emacs + +to the beginning of /etc/inputrc, or bracket the key bindings in +/etc/inputrc with these lines + + $if mode=emacs + [...] + $endif + +F7) Why do bash-2.05a and bash-2.05b fail to compile `printf.def' on + HP/UX 11.x? + +HP/UX's support for long double is imperfect at best. + +GCC will support it without problems, but the HP C library functions +like strtold(3) and printf(3) don't actually work with long doubles. +HP implemented a `long_double' type as a 4-element array of 32-bit +ints, and that is what the library functions use. The ANSI C +`long double' type is a 128-bit floating point scalar. + +The easiest fix, until HP fixes things up, is to edit the generated +config.h and #undef the HAVE_LONG_DOUBLE line. After doing that, +the compilation should complete successfully. + +Section G: How can I get bash to do certain common things? + +G1) How can I get bash to read and display eight-bit characters? + +This is a process requiring several steps. + +First, you must ensure that the `physical' data path is a full eight +bits. For xterms, for example, the `vt100' resources `eightBitInput' +and `eightBitOutput' should be set to `true'. + +Once you have set up an eight-bit path, you must tell the kernel and +tty driver to leave the eighth bit of characters alone when processing +keyboard input. Use `stty' to do this: + + stty cs8 -istrip -parenb + +For old BSD-style systems, you can use + + stty pass8 + +You may also need + + stty even odd + +Finally, you need to tell readline that you will be inputting and +displaying eight-bit characters. You use readline variables to do +this. These variables can be set in your .inputrc or using the bash +`bind' builtin. Here's an example using `bind': + + bash$ bind 'set convert-meta off' + bash$ bind 'set meta-flag on' + bash$ bind 'set output-meta on' + +The `set' commands between the single quotes may also be placed +in ~/.inputrc. + +G2) How do I write a function `x' to replace builtin command `x', but + still invoke the command from within the function? + +This is why the `command' and `builtin' builtins exist. The +`command' builtin executes the command supplied as its first +argument, skipping over any function defined with that name. The +`builtin' builtin executes the builtin command given as its first +argument directly. + +For example, to write a function to replace `cd' that writes the +hostname and current directory to an xterm title bar, use +something like the following: + + cd() + { + builtin cd "$@" && xtitle "$HOST: $PWD" + } + +This could also be written using `command' instead of `builtin'; +the version above is marginally more efficient. + +G3) How can I find the value of a shell variable whose name is the value + of another shell variable? + +Versions of Bash newer than Bash-2.0 support this directly. You can use + + ${!var} + +For example, the following sequence of commands will echo `z': + + var1=var2 + var2=z + echo ${!var1} + +For sh compatibility, use the `eval' builtin. The important +thing to remember is that `eval' expands the arguments you give +it again, so you need to quote the parts of the arguments that +you want `eval' to act on. + +For example, this expression prints the value of the last positional +parameter: + + eval echo \"\$\{$#\}\" + +The expansion of the quoted portions of this expression will be +deferred until `eval' runs, while the `$#' will be expanded +before `eval' is executed. In versions of bash later than bash-2.0, + + echo ${!#} + +does the same thing. + +This is not the same thing as ksh93 `nameref' variables, though the syntax +is similar. I may add namerefs in a future bash version. + +G4) How can I make the bash `time' reserved word print timing output that + looks like the output from my system's /usr/bin/time? + +The bash command timing code looks for a variable `TIMEFORMAT' and +uses its value as a format string to decide how to display the +timing statistics. + +The value of TIMEFORMAT is a string with `%' escapes expanded in a +fashion similar in spirit to printf(3). The manual page explains +the meanings of the escape sequences in the format string. + +If TIMEFORMAT is not set, bash acts as if the following assignment had +been performed: + + TIMEFORMAT=$'\nreal\t%3lR\nuser\t%3lU\nsys\t%3lS' + +The POSIX.2 default time format (used by `time -p command') is + + TIMEFORMAT=$'real %2R\nuser %2U\nsys %2S' + +The BSD /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\t%1R real\t%1U user\t%1S sys' + +The System V /usr/bin/time format can be emulated with: + + TIMEFORMAT=$'\nreal\t%1R\nuser\t%1U\nsys\t%1S' + +The ksh format can be emulated with: + + TIMEFORMAT=$'\nreal\t%2lR\nuser\t%2lU\nsys\t%2lS' + +G5) How do I get the current directory into my prompt? + +Bash provides a number of backslash-escape sequences which are expanded +when the prompt string (PS1 or PS2) is displayed. The full list is in +the manual page. + +The \w expansion gives the full pathname of the current directory, with +a tilde (`~') substituted for the current value of $HOME. The \W +expansion gives the basename of the current directory. To put the full +pathname of the current directory into the path without any tilde +subsitution, use $PWD. Here are some examples: + + PS1='\w$ ' # current directory with tilde + PS1='\W$ ' # basename of current directory + PS1='$PWD$ ' # full pathname of current directory + +The single quotes are important in the final example to prevent $PWD from +being expanded when the assignment to PS1 is performed. + +G6) How can I rename "*.foo" to "*.bar"? + +Use the pattern removal functionality described in D3. The following `for' +loop will do the trick: + + for f in *.foo; do + mv $f ${f%foo}bar + done + +G7) How can I translate a filename from uppercase to lowercase? + +The script examples/functions/lowercase, originally written by John DuBois, +will do the trick. The converse is left as an exercise. + +G8) How can I write a filename expansion (globbing) pattern that will match + all files in the current directory except "." and ".."? + +You must have set the `extglob' shell option using `shopt -s extglob' to use +this: + + echo .!(.|) * + +A solution that works without extended globbing is given in the Unix Shell +FAQ, posted periodically to comp.unix.shell. + +Section H: Where do I go from here? + +H1) How do I report bugs in bash, and where should I look for fixes and + advice? + +Use the `bashbug' script to report bugs. It is built and +installed at the same time as bash. It provides a standard +template for reporting a problem and automatically includes +information about your configuration and build environment. + +`bashbug' sends its reports to bug-bash@gnu.org, which +is a large mailing list gatewayed to the usenet newsgroup gnu.bash.bug. + +Bug fixes, answers to questions, and announcements of new releases +are all posted to gnu.bash.bug. Discussions concerning bash features +and problems also take place there. + +To reach the bash maintainers directly, send mail to +bash-maintainers@gnu.org. + +H2) What kind of bash documentation is there? + +First, look in the doc directory in the bash distribution. It should +contain at least the following files: + +bash.1 an extensive, thorough Unix-style manual page +builtins.1 a manual page covering just bash builtin commands +bashref.texi a reference manual in GNU tex`info format +bashref.info an info version of the reference manual +FAQ this file +article.ms text of an article written for The Linux Journal +readline.3 a man page describing readline + +Postscript, HTML, and ASCII files created from the above source are +available in the documentation distribution. + +There is additional documentation available for anonymous FTP from host +ftp.cwru.edu in the `pub/bash' directory. + +Cameron Newham and Bill Rosenblatt have written a book on bash, published +by O'Reilly and Associates. The book is based on Bill Rosenblatt's Korn +Shell book. The title is ``Learning the Bash Shell'', and the ISBN number +is 1-56592-147-X. Look for it in fine bookstores near you. This book +covers bash-1.14, but has an appendix describing some of the new features +in bash-2.0. + +A second edition of this book is available, published in January, 1998. +The ISBN number is 1-56592-347-2. Look for it in the same fine bookstores +or on the web. + +The GNU Bash Reference Manual has been published as a printed book by +Network Theory Ltd (Paperback, ISBN: 0-9541617-7-7, Feb 2003). It covers +bash-2.0 and is available from most online bookstores (see +http://www.network-theory.co.uk/bash/manual/ for details). The publisher +will donate $1 to the Free Software Foundation for each copy sold. + +H3) What's coming in future versions? + +These are features I hope to include in a future version of bash. + +a better bash debugger (a minimally-tested version is included with bash-2.05b) +associative arrays +co-processes, but with a new-style syntax that looks like function declaration + +H4) What's on the bash `wish list' for future versions? + +These are features that may or may not appear in a future version of bash. + +breaking some of the shell functionality into embeddable libraries +a module system like zsh's, using dynamic loading like builtins +better internationalization using GNU `gettext' +date-stamped command history +a bash programmer's guide with a chapter on creating loadable builtins +a better loadable interface to perl with access to the shell builtins and + variables (contributions gratefully accepted) +ksh93-like `nameref' variables +ksh93-like `+=' variable assignment operator +ksh93-like `xx.yy' variables (including some of the .sh.* variables) and + associated disipline functions +Some of the new ksh93 pattern matching operators, like backreferencing + +H5) When will the next release appear? + +The next version will appear sometime in 2002.

Bash is an sh-compatible shell that +incorporates useful features from the Korn shell (ksh) and C shell +(csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 +Shell and Tools standard. It offers functional improvements over sh +for both programming and interactive use. In addition, most sh scripts +can be run by Bash without modification. + +Bash is quite portable. It uses a configuration system that discovers +characteristics of the compilation platform at build time, and may +therefore be built on nearly every version of UNIX. Ports to +UNIX-like systems such as QNX and Minix and to non-UNIX systems such +as OS/2, Windows 95, and Windows NT are available. + +Bash includes the following features: + +Editing and Completion + +Bash offers a command-line editing facility which permits users to +edit command lines using familiar emacs or vi-style editing commands. +Editing allows corrections to be made without having to erase back +to the point of error or start the command line anew. The editing +facilities include a feature that allows users to complete command and +file names. + +The Bash line editing library is fully customizable. Users may define +their own key bindings -- the action taken when a key is pressed. A +number of variables to fine-tune editing behavior are also available. + +History and Command Re-entry + +The Bash history feature remembers commands entered to the shell and +allows them to be recalled and re-executed. The history list may be +of unlimited size. Bash allows users to search for previous commands +and reuse portions of those commands when composing new ones. The +history list may be saved across shell sessions. + +Bash allows users to control which commands are saved on the history +list. + +Job Control + +On systems that support it, Bash provides an interface to the +operating system's job control facilities, which allow processes +to be suspended and restarted, and moved between the foreground +and background. Bash allows users to selectively `forget' about +background jobs. + +Shell Functions and Aliases + +These mechanisms are available to bind a user-selected identifier to a +list of commands that will be executed when the identifier is used as +a command name. Functions allow local variables and recursion, and +have access to the environment of the calling shell. Aliases may be +used to create a mnemonic for a command name, expand a single word to +a complex command, or ensure that a command is called with a basic set +of options. + +Arrays + +Bash-2.0 supports indexed arrays of unlimited size. The subscript for +an array is an arithmetic expression. Arrays may be assigned to with +a new compound assignment syntax, and several builtins have options to +operate on array variables. Bash includes a number of built-in array +variables. + +Arithmetic + +Bash allows users to perform integer arithmetic in any base from two +to sixty-four. Nearly all of the C language arithmetic operators are +available with the same syntax and precedence as in C. Arithmetic +expansion allows an arithmetic expression to be evaluated and the +result substituted into the command line. Shell variables can be used +as operands, and the value of an expression may be assigned to a +variable. + +An arithmetic expression may be used as a command; the exit status of +the command is the value of the expression. + +ANSI-C Quoting + +There is a new quoting syntax that allows backslash-escaped characters +in strings to be expanded according to the ANSI C standard. + +Tilde Expansion + +Users' home directories may be expanded using this feature. Words +beginning with a tilde may also be expanded to the current or previous +working directory. + +Brace Expansion + +Brace expansion is a convenient way to generate a list of strings that +share a common prefix or suffix. + +Substring Capabilities + +Bash allows new strings to be created by removing leading or trailing +substrings from existing variable values, or by specifying a starting +offset and length. Portions of variable values may be matched against +shell patterns and the matching portion removed or a new value +substituted. + +Indirect Variable Expansion + +Bash makes it easy to find the value of a shell variable whose name is +the value of another variable. + +Expanded I/O Capabilities + +Bash provides several input and output features not available in sh, +including the ability to: + + o specify a file or file descriptor for both input and output + o read from or write to asynchronous processes using named pipes + o read lines ending in backslash + o display a prompt on the terminal before a read + o format menus and interpret responses to them + o echo lines exactly as input without escape processing + +Control of Builtin Commands + +Bash implements several builtin commands to give users more control +over which commands are executed. The enable builtin allows other +builtin commands to be selectively enabled or disabled. The command +and builtin builtins change the order in which the shell searches for +commands. + +On systems that provide dynamic loading, new builtins may be loaded +into a running shell from a shared object file. These new builtins +have access to all of the shell facilities. + +Help + +Bash includes a built-in help facility. + +Shell Optional Behavior + +There is a great deal of customizable shell behavior. The shopt +builtin command provides a unified interface that allows users to +alter shell defaults. + +Prompt Customization + +Bash allows the primary and secondary prompts to be customized by +interpreting a number of backslash-escaped special characters. +Parameter and variable expansion is also performed on the values of +the primary and secondary prompt strings before they are displayed. + +Security + +Bash provides a restricted shell environment. It is also possible to +control the execution of setuid/setgid scripts. + +Directory Stack + +Bash provides a `directory stack', to which directories may be added +and removed. The current directory may be changed to any directory in +the stack. It is easy to toggle between two directories in the stack. +The directory stack may be saved and restored across different shell +invocations. + +POSIX Mode + +Bash is nearly completely conformant to POSIX.2. POSIX mode changes +those few areas where the Bash default behavior differs from the +standard to match the standard. In POSIX mode, Bash is POSIX.2 +compliant. + +Internationalization + +Bash provides a new quoting syntax that allows strings to be +translated according to the current locale. The locale in which the +shell itself runs may also be changed, so that the shell messages +themselves may be language-specific. + +The command-line editing facilities allow the input of eight-bit +characters, so most of the ISO-8859 family of character sets are +supported. + +Command Timing + +Bash allows external commands, shell builtin commands and shell functions +to be timed.

The +current developer and maintainer is Chet Ramey, a volunteer who +works at Case Western Reserve University. +.NH 1 +What's POSIX, anyway? +.PP +.I POSIX +is a name originally coined by Richard Stallman for a family of open +system standards based on \s-1UNIX\s+1. There are a number of aspects of \s-1UNIX\s+1 +under consideration for standardization, from the basic system services +at the system call and C library level to applications and tools to system +administration and management. Each area of standardization is +assigned to a working group in the 1003 series. +.PP +The POSIX Shell and Utilities standard has been developed by IEEE Working +Group 1003.2 (POSIX.2).\(dd +.FS +\(ddIEEE, \fIIEEE Standard for Information Technology -- Portable +Operating System Interface (POSIX) Part 2: Shell and Utilities\fP, +1992. +.FE +It concentrates on the command interpreter +interface and utility programs +commonly executed from the command line or by other programs. +An initial version of the standard has been +approved and published by the IEEE, and work is currently underway to +update it. +There are four primary areas of work in the 1003.2 standard: +.IP \(bu +Aspects of the shell's syntax and command language. +A number of special builtins such as +.B cd +and +.B exec +are being specified as part of the shell, since their +functionality usually cannot be implemented by a separate executable; +.IP \(bu +A set of utilities to be called by shell scripts and applications. +Examples are programs like +.I sed, +.I tr, +and +.I awk. +Utilities commonly implemented as shell builtins +are described in this section, such as +.B test +and +.B kill . +An expansion of this section's scope, termed the User Portability +Extension, or UPE, has standardized interactive programs such as +.I vi +and +.I mailx; +.IP \(bu +A group of functional interfaces to services provided by the +shell, such as the traditional \f(CRsystem()\fP +C library function. There are functions to perform shell word +expansions, perform filename expansion (\fIglobbing\fP), obtain values +of POSIX.2 system configuration variables, retrieve values of +environment variables (\f(CRgetenv()\fP\^), and other services; +.IP \(bu +A suite of \*Qdevelopment\*U utilities such as +.I c89 +(the POSIX.2 version of \fIcc\fP), +and +.I yacc. +.PP +Bash is concerned with the aspects of the shell's behavior +defined by POSIX.2. The shell command language has of +course been standardized, including the basic flow control +and program execution constructs, I/O redirection and +pipelining, argument handling, variable expansion, and quoting. +The +.I special +builtins, which must be implemented as part of the shell to +provide the desired functionality, are specified as being +part of the shell; examples of these are +.B eval +and +.B export . +Other utilities appear in the sections of POSIX.2 not +devoted to the shell which are commonly (and in some +cases must be) implemented as builtin commands, such as +.B read +and +.B test . +POSIX.2 also specifies aspects of the shell's +interactive behavior as part of +the UPE, including job control and command line editing. +Interestingly enough, only \fIvi\fP-style line editing commands +have been standardized; \fIemacs\fP editing commands were left +out due to objections. +.PP +While POSIX.2 includes much of what the shell has traditionally +provided, some important things have been omitted as being +\*Qbeyond its scope.\*U There is, for instance, no mention of +a difference between a +.I login +shell and any other interactive shell (since POSIX.2 does not +specify a login program). No fixed startup files are defined, +either \- the standard does not mention +.I .profile . +.NH 1 +Basic Bash features +.PP +Since the Bourne shell +provides Bash with most of its philosophical underpinnings, +Bash inherits most of its features and functionality from sh. +Bash implements all of the traditional sh flow +control constructs (\fIfor\fP, \fIif\fP, \fIwhile\fP, etc.). +All of the Bourne shell builtins, including those not specified in +the POSIX.2 standard, appear in Bash. Shell \fIfunctions\fP, +introduced in the SVR2 version of the Bourne shell, +are similar to shell scripts, but are defined using a special +syntax and are executed in the same process as the calling shell. +Bash has shell functions +which behave in a fashion upward-compatible with sh functions. +There are certain shell +variables that Bash interprets in the same way as sh, such as +.B PS1 , +.B IFS , +and +.B PATH . +Bash implements essentially the same grammar, parameter and +variable expansion semantics, redirection, and quoting as the +Bourne shell. Where differences appear between the POSIX.2 +standard and traditional sh behavior, Bash follows POSIX. +.PP +The Korn Shell (\fBksh\fP) is a descendent of the Bourne shell written +at AT&T Bell Laboratories by David Korn\(dg. It provides a number of +useful features that POSIX and Bash have adopted. Many of the +interactive facilities in POSIX.2 have their roots in the ksh: +for example, the POSIX and ksh job control facilities are nearly +identical. Bash includes features from the Korn Shell for both +interactive use and shell programming. For programming, Bash provides +variables such as +.B RANDOM +and +.B REPLY , +the +.B typeset +builtin, +the ability to remove substrings from variables based on patterns, +and shell arithmetic. +.FS +\(dgMorris Bolsky and David Korn, \fIThe KornShell Command and +Programming Language\fP, Prentice Hall, 1989. +.FE +.B RANDOM +expands to a random number each time it is referenced; assigning a +value to +.B RANDOM +seeds the random number generator. +.B REPLY +is the default variable used by the +.B read +builtin when no variable names are supplied as arguments. +The +.B typeset +builtin is used to define variables and give them attributes +such as \fBreadonly\fP. +Bash arithmetic allows the evaluation of an expression and the +substitution of the result. Shell variables may be used as operands, +and the result of an expression may be assigned to a variable. +Nearly all of the operators from the C language are available, +with the same precedence rules: +.SE +$ echo $((3 + 5 * 32)) +163 +.EE +.LP +For interactive use, Bash implements ksh-style aliases and builtins +such as +.B fc +(discussed below) and +.B jobs . +Bash aliases allow a string to be substituted for a command name. +They can be used to create a mnemonic for a \s-1UNIX\s+1 command +name (\f(CRalias del=rm\fP), to expand a single word to a complex command +(\f(CRalias news='xterm -g 80x45 -title trn -e trn -e -S1 -N &'\fP), or to +ensure that a command is invoked with a basic set of options +(\f(CRalias ls="/bin/ls -F"\fP). +.PP +The C shell (\fBcsh\fP)\(dg, originally written by Bill Joy while at +Berkeley, is widely used and quite popular for its interactive +facilities. Bash includes a csh-compatible history expansion +mechanism (\*Q! history\*U), brace expansion, access to a stack +of directories via the +.B pushd , +.B popd , +and +.B dirs +builtins, and tilde expansion, to generate users' home directories. +Tilde expansion has also been adopted by both the Korn Shell and +POSIX.2. +.FS +\(dgBill Joy, An Introduction to the C Shell, \fIUNIX User's Supplementary +Documents\fP, University of California at Berkeley, 1986. +.FE +.PP +There were certain areas in which POSIX.2 felt standardization +was necessary, but no existing implementation provided the proper +behavior. The working group invented and standardized functionality +in these areas, which Bash implements. The +.B command +builtin was invented so that shell functions could be written to +replace builtins; it makes the capabilities of the builtin +available to the function. The reserved word \*Q!\*U was added +to negate the return value of a command or pipeline; it was nearly +impossible to express \*Qif not x\*U cleanly using the sh language. +There exist multiple incompatible implementations of the +.B test +builtin, which tests files for type and other attributes and performs +arithmetic and string comparisons. +POSIX considered none of these correct, so the standard +behavior was specified in terms of the number of arguments to the +command. POSIX.2 dictates exactly what will happen when four or +fewer arguments are given to +.B test , +and leaves the behavior undefined when more arguments are supplied. +Bash uses the POSIX.2 algorithm, which was conceived by David Korn. +.NH 2 +Features not in the Bourne Shell +.PP +There are a number of minor differences between Bash and the +version of sh present on most other versions of \s-1UNIX\s+1. The majority +of these are due to the POSIX standard, but some are the result of +Bash adopting features from other shells. For instance, Bash +includes the new \*Q!\*U reserved word, the +.B command +builtin, the ability of the +.B read +builtin to correctly return a line ending with a backslash, symbolic +arguments to the +.B umask +builtin, variable substring removal, a way to get the length of a variable, +and the new algorithm for the +.B test +builtin from the POSIX.2 standard, none of which appear in sh. +.PP +Bash also implements the \*Q$(...)\*U command substitution syntax, +which supersedes the sh `...` construct. +The \*Q$(...)\*U construct expands to the output of the command +contained within the +parentheses, with trailing newlines removed. The sh syntax is +accepted for backwards compatibility, but the \*Q$(...)\*U form +is preferred because its quoting rules are much simpler and it +is easier to nest. +.PP +The Bourne shell does not provide such features as brace expansion, +the ability +to define a variable and a function with the same name, local variables +in shell functions, the ability to enable and disable individual +builtins or write a function to replace a builtin, or a means to +export a shell function to a child process. +.PP +Bash has closed +a long-standing shell security hole by not using the +.B $IFS +variable to split each word read by the shell, but splitting only +the results of expansion (ksh and the 4.4 BSD sh have fixed this +as well). Useful behavior such as a means to abort +execution of a script read with the \*Q.\*U command using the +\fBreturn\fP builtin or automatically +exporting variables in the shell's environment to children is also +not present in the Bourne shell. Bash provides a much more powerful +environment for both interactive use and programming. +.NH 1 +Bash-specific Features +.PP +This section details a few of the features which make Bash unique. +Most of them provide improved interactive use, but a few programming +improvements are present as well. Full descriptions of these +features can be found in the Bash documentation. +.NH 2 +Startup Files +.PP +Bash executes startup files differently than other shells. The Bash +behavior is a compromise between the csh principle of startup files +with fixed names executed for each shell and the sh +\*Qminimalist\*U behavior. An interactive instance of Bash started +as a login shell reads and executes +.I ~/.bash_profile +(the file .bash_profile in the user's home directory), if it exists. +An interactive non-login shell reads and executes +.I ~/.bashrc . +A non-interactive shell (one begun to execute a shell script, for +example) reads no fixed startup file, but uses the value of the variable +.B $ENV , +if set, as the name of a startup file. The ksh practice of reading +.B $ENV +for every shell, with the accompanying difficulty of defining the +proper variables and functions for interactive and non-interactive +shells or having the file read only for interactive shells, was +considered too complex. Ease of use won out here. Interestingly, +the next release of ksh will change to reading +.B $ENV +only for interactive shells. +.NH 2 +New Builtin Commands +.PP +There are a few builtins which are new or have been extended in Bash. +The +.B enable +builtin allows builtin commands to be turned on and off arbitrarily. +To use the version of +.I echo +found in a user's search path rather than the Bash builtin, +\f(CRenable -n echo\fP suffices. The +.B help +builtin provides +quick synopses of the shell facilities without requiring +access to a manual page. +.B Builtin +is similar to +.B command +in that it bypasses shell functions and directly executes builtin +commands. Access to a csh-style stack of directories is provided +via the +.B pushd , +.B popd , +and +.B dirs +builtins. +.B Pushd +and +.B popd +insert and remove directories from the stack, respectively, and +.B dirs +lists the stack contents. On systems that allow fine-grained control +of resources, the +.B ulimit +builtin can be used to tune these settings. +.B Ulimit +allows a user to control, +among other things, whether core dumps are to be generated, +how much memory the shell or a child process is allowed to allocate, +and how large a file created by a child process can grow. The +.B suspend +command will stop the shell process when job control is active; most +other shells do not allow themselves to be stopped like that. +.B Type, +the Bash answer to +.B which +and +.B whence, +shows what will happen when a word is typed as a command: +.SE +$ type export +export is a shell builtin +$ type -t export +builtin +$ type bash +bash is /bin/bash +$ type cd +cd is a function +cd () +{ + builtin cd ${1+"$@"} && xtitle $HOST: $PWD +} +.EE +.LP +Various +modes tell what a command word is (reserved word, alias, function, builtin, +or file) or which version of a command will be executed based on +a user's search path. Some of this functionality has been adopted +by POSIX.2 and folded into the +.B command +utility. +.NH 2 +Editing and Completion +.PP +One area in which Bash shines is command line editing. Bash uses the +.I readline +library to read and edit lines when interactive. Readline is a +powerful and flexible input facility that a user can configure to +individual tastes. It allows lines to be edited using either emacs +or vi commands, where those commands are appropriate. The full +capability of emacs is not present \- there is no way to execute +a named command with M-x, for instance \- but the existing commands +are more than adequate. The vi mode is compliant with +the command line editing standardized by POSIX.2. +.PP +Readline is fully customizable. In addition to the basic commands +and key bindings, the library allows users to define additional +key bindings using a startup file. The +.I inputrc +file, which defaults to the file +.I ~/.inputrc , +is read each time readline initializes, permitting users to +maintain a consistent interface across a set of programs. Readline +includes an extensible interface, so each program using the +library can add its own bindable commands and program-specific +key bindings. Bash uses this facility to add bindings +that perform history expansion or shell word expansions on the current +input line. +.PP +Readline interprets a number of +variables which further tune its behavior. Variables +exist to control whether or not eight-bit characters are directly +read as input or converted to meta-prefixed key sequences (a +meta-prefixed key sequence consists of the character with the +eighth bit zeroed, preceded by the +.I meta-prefix +character, usually escape, which selects an alternate keymap), to +decide whether to output characters with the eighth bit set +directly or as a meta-prefixed key sequence, whether or not to +wrap to a new screen line when a line being edited is longer than +the screen width, the keymap to which subsequent key bindings should +apply, or even what happens when readline wants to +ring the terminal's bell. All of these variables can be set in +the inputrc file. +.PP +The startup file understands a set of C +preprocessor-like conditional constructs which allow variables or +key bindings to be assigned based on the application using readline, +the terminal currently being used, or the editing mode. Users can +add program-specific bindings to make their lives easier: I have +bindings that let me edit the value of +.B $PATH +and double-quote the current or previous word: +.SE +# Macros that are convenient for shell interaction +$if Bash +# edit the path +"\eC-xp": "PATH=${PATH}\ee\eC-e\eC-a\eef\eC-f" +# prepare to type a quoted word -- insert open and close double +# quotes and move to just after the open quote +"\eC-x\e"": "\e"\e"\eC-b" +# Quote the current or previous word +"\eC-xq": "\eeb\e"\eef\e"" +$endif +.EE +.LP +There is a readline +command to re-read the file, so users can edit the file, change +some bindings, and begin to use them almost immediately. +.PP +Bash implements the +.B bind +builtin for more dyamic control of readline than the startup file +permits. +.B Bind +is used in several ways. In +.I list +mode, it can display the current key bindings, list all the +readline editing directives available for binding, list which keys +invoke a given directive, or output the current set of key +bindings in a format that can be incorporated directly into an inputrc +file. In +.I batch +mode, it reads a series of key bindings directly from a file and +passes them to readline. In its most common usage, +.B bind +takes a single string and passes it directly to readline, which +interprets the line as if it had just been read from the inputrc file. +Both key bindings and variable assignments may appear in the +string given to +.B bind . +.PP +The readline library also provides an interface for \fIword completion\fP. +When the +.I completion +character (usually TAB) is typed, readline looks at the word currently +being entered and computes the set of filenames of which the current +word is a valid prefix. +If there is only one possible completion, the +rest of the characters are inserted directly, otherwise the +common prefix of the set of filenames is added to the current word. +A second TAB character entered immediately after a non-unique +completion causes readline to list the possible completions; there is +an option to have the list displayed immediately. +Readline provides hooks so that applications can provide specific types +of completion before the default filename completion is attempted. +This is quite flexible, though it is not completely user-programmable. +Bash, for example, can complete filenames, command names (including aliases, +builtins, shell reserved words, shell functions, and executables found +in the file system), shell variables, usernames, and hostnames. It +uses a set of heuristics that, while not perfect, is generally quite +good at determining what type of completion to attempt. +.NH 2 +History +.PP +Access to the list of commands previously entered (the \fIcommand history\fP) +is provided jointly by Bash and the readline library. Bash provides +variables (\fB$HISTFILE\fP, \fB$HISTSIZE\fP, and \fB$HISTCONTROL\fP) +and the +.B history +and +.B fc +builtins to manipulate the history list. +The value of +.B $HISTFILE +specifes the file where Bash writes the command history on exit and +reads it on startup. +.B $HISTSIZE +is used to limit the number of commands saved in the history. +.B $HISTCONTROL +provides a crude form of control over which commands are saved on +the history list: a value of +.I ignorespace +means to not save commands which begin with a space; a value of +.I ignoredups +means to not save commands identical to the last command saved. +\fB$HISTCONTROL\fP was named \fB$history_control\fP in earlier +versions of Bash; the old name is still accepted for backwards +compatibility. The +.B history +command can read or write files containing the history list +and display the current list contents. The +.B fc +builtin, adopted from POSIX.2 and the Korn Shell, allows display +and re-execution, with optional editing, +of commands from the history list. The readline +library offers a set of commands to search the history list for +a portion of the current input line or a string typed by the user. +Finally, the +.I history +library, generally incorporated directly into the readline library, +implements a facility for history recall, expansion, and re-execution +of previous commands very similar to csh +(\*Qbang history\*U, so called because the exclamation point +introduces a history substitution): +.SE +$ echo a b c d e +a b c d e +$ !! f g h i +echo a b c d e f g h i +a b c d e f g h i +$ !-2 +echo a b c d e +a b c d e +$ echo !-2:1-4 +echo a b c d +a b c d +.EE +.LP +The command history is only +saved when the shell is interactive, so it is not available for use +by shell scripts. +.NH 2 +New Shell Variables +.PP +There are a number of convenience variables that Bash interprets +to make life easier. These include +.B FIGNORE , +which is a set of filename suffixes identifying files to exclude when +completing filenames; +.B HOSTTYPE , +which is automatically set to a string describing the type of +hardware on which Bash is currently executing; +.B command_oriented_history , +which directs Bash to save all lines of a multiple-line +command such as a \fIwhile\fP or \fIfor\fP loop in a single +history entry, allowing easy re-editing; and +.B IGNOREEOF , +whose value indicates the number of consecutive EOF characters that +an interactive shell will read before exiting \- an easy way to keep +yourself from being logged out accidentally. The +.B auto_resume +variable alters the way the shell treats simple command names: +if job control is active, and this variable is set, single-word +simple commands without redirections cause the shell to first +look for and restart a suspended job with that name before +starting a new process. +.NH 2 +Brace Expansion +.PP +Since sh offers no convenient way to generate arbitrary strings that +share a common prefix or suffix (filename expansion requires that +the filenames exist), Bash implements \fIbrace expansion\fP, a +capability picked up from csh. +Brace expansion is similar to filename expansion, but the strings +generated need not correspond to existing files. A brace expression +consists of an optional +.I preamble , +followed by a pair of braces enclosing a series of comma-separated +strings, and an optional +.I postamble . +The preamble is prepended to each string within the braces, and the +postamble is then appended to each resulting string: +.SE +$ echo a{d,c,b}e +ade ace abe +.EE +.LP +As this example demonstrates, the results of brace expansion are not +sorted, as they are by filename expansion. +.NH 2 +Process Substitution +.PP +On systems that can support it, Bash provides a facility known as +\fIprocess substitution\fP. Process substitution is similar to command +substitution in that its specification includes a command to execute, +but the shell does not collect the command's output and insert it into +the command line. Rather, Bash opens a pipe to the command, which +is run in the background. The shell uses named pipes (FIFOs) or the +.I /dev/fd +method of naming open files to expand the process +substitution to a filename which connects to the pipe when opened. +This filename becomes the result of the expansion. Process substitution +can be used to compare the outputs of two different versions of an +application as part of a regression test: +.SE +$ cmp <(old_prog) <(new_prog) +.EE +.NH 2 +Prompt Customization +.PP +One of the more popular interactive features that Bash provides is +the ability to customize the prompt. Both +.B $PS1 +and +.B $PS2, +the primary and secondary prompts, are expanded before being +displayed. Parameter and variable expansion is performed when +the prompt string is expanded, so any shell variable can be +put into the prompt (e.g., +.B $SHLVL , +which indicates how deeply the current shell is nested). +Bash specially interprets characters in the prompt string +preceded by a backslash. Some of these backslash escapes are +replaced with +the current time, the date, the current working directory, +the username, and the command number or history number of the command +being entered. There is even a backslash escape to cause the shell +to change its prompt when running as root after an \fIsu\fP. +Before printing each primary prompt, Bash expands the variable +.B $PROMPT_COMMAND +and, if it has a value, executes the expanded value as a command, +allowing additional prompt customization. For example, this assignment +causes the current user, the current host, the time, the last +component of the current working directory, the level of shell +nesting, and the history number of the current command to be embedded +into the primary prompt: +.SE +$ PS1='\eu@\eh [\et] \eW($SHLVL:\e!)\e$ ' +chet@odin [21:03:44] documentation(2:636)$ cd .. +chet@odin [21:03:54] src(2:637)$ +.EE +.LP +The string being assigned is surrounded by single quotes so that if +it is exported, the value of +.B $SHLVL +will be updated by a child shell: +.SE +chet@odin [21:17:35] src(2:638)$ export PS1 +chet@odin [21:17:40] src(2:639)$ bash +chet@odin [21:17:46] src(3:696)$ +.EE +.LP +The \fP\e$\fP escape is displayed +as \*Q\fB$\fP\*U when running as a normal user, but as \*Q\fB#\fP\*U when +running as root. +.NH 2 +File System Views +.PP +Since Berkeley introduced symbolic links in 4.2 BSD, one of their most +annoying properties has been the \*Qwarping\*U to a completely +different area of the file system when using +.B cd , +and the resultant non-intuitive behavior of \*Q\fBcd ..\fP\*U. +The \s-1UNIX\s+1 kernel treats symbolic links +.I physically . +When the kernel is translating a pathname +in which one component is a symbolic link, it replaces all or part +of the pathname while processing the link. If the contents of the symbolic +link begin with a slash, the kernel replaces the +pathname entirely; if not, the link contents replace +the current component. In either case, the symbolic link +is visible. If the link value is an absolute pathname, +the user finds himself in a completely different part of the file +system. +.PP +Bash provides a +.I logical +view of the file system. In this default mode, command and filename +completion and builtin commands such as +.B cd +and +.B pushd +which change the current working directory transparently follow +symbolic links as if they were directories. +The +.B $PWD +variable, which holds the shell's idea of the current working directory, +depends on the path used to reach the directory rather than its +physical location in the local file system hierarchy. For example: +.SE +$ cd /usr/local/bin +$ echo $PWD +/usr/local/bin +$ pwd +/usr/local/bin +$ /bin/pwd +/net/share/sun4/local/bin +$ cd .. +$ pwd +/usr/local +$ /bin/pwd +/net/share/sun4/local +$ cd .. +$ pwd +/usr +$ /bin/pwd +/usr +.EE +.LP +One problem with this, of +course, arises when programs that do not understand the shell's logical +notion of the file system interpret \*Q..\*U differently. This generally +happens when Bash completes filenames containing \*Q..\*U according to a +logical hierarchy which does not correspond to their physical location. +For users who find this troublesome, a corresponding +.I physical +view of the file system is available: +.SE +$ cd /usr/local/bin +$ pwd +/usr/local/bin +$ set -o physical +$ pwd +/net/share/sun4/local/bin +.EE +.NH 2 +Internationalization +.PP +One of the most significant improvements in version 1.13 of Bash was the +change to \*Qeight-bit cleanliness\*U. Previous versions used the +eighth bit of characters to mark whether or not they were +quoted when performing word expansions. While this did not affect +the majority of users, most of whom used only seven-bit ASCII characters, +some found it confining. Beginning with version 1.13, Bash +implemented a different quoting mechanism that did not alter the +eighth bit of characters. This allowed Bash +to manipulate files with \*Qodd\*U characters in their names, but +did nothing to help users enter those names, so +version 1.13 introduced changes to readline that +made it eight-bit clean as well. Options exist that force readline to +attach no special significance to characters with the eighth bit set +(the default behavior is to convert these characters to meta-prefixed +key sequences) and to output these characters without conversion to +meta-prefixed sequences. These changes, along with the expansion of +keymaps to a full eight bits, enable readline to work with most of the +ISO-8859 family of character sets, used by many European countries. +.NH 2 +POSIX Mode +.PP +Although Bash is intended to be POSIX.2 conformant, there are areas in +which the default behavior is not compatible with the standard. For +users who wish to operate in a strict POSIX.2 environment, Bash +implements a \fIPOSIX mode\fP. When this mode is active, Bash modifies +its default operation where it differs from POSIX.2 to match the +standard. POSIX mode is entered when Bash is started with the +.B -posix +option. This feature is also available as an option to the +\fBset\fP builtin, \fBset -o posix\fP. +For compatibility with other GNU software that attempts to be POSIX.2 +compliant, Bash also enters POSIX mode if the variable +.B $POSIXLY_CORRECT +is set when Bash is started or assigned a value during execution. +.B $POSIX_PEDANTIC +is accepted as well, to be compatible with some older GNU utilities. +When Bash is started in POSIX mode, for example, it sources the +file named by the value of +.B $ENV +rather than the \*Qnormal\*U startup files, and does not allow +reserved words to be aliased. +.NH 1 +New Features and Future Plans +.PP +There are several features introduced in the current +version of Bash, version 1.14, and a number under consideration +for future releases. This section will briefly detail the new +features in version 1.14 and describe several features +that may appear in later versions. +.NH 2 +New Features in Bash-1.14 +.PP +The new features available in Bash-1.14 answer several of +the most common requests for enhancements. Most notably, there +is a mechanism +for including non-visible character sequences in prompts, such as +those which cause a terminal to print characters in different +colors or in standout mode. There was nothing preventing the use +of these sequences in earlier +versions, but the readline redisplay algorithm assumed each +character occupied physical screen space and would wrap lines +prematurely. +.PP +Readline has a few new +variables, several new bindable commands, and some additional +emacs mode default key bindings. A new history search +mode has been implemented: in this mode, readline searches the +history for lines beginning with the characters between the +beginning of the current line and the cursor. The existing readline +incremental search commands no longer match identical lines more +than once. +Filename completion now expands variables in directory names. +The history expansion facilities are now nearly +completely csh-compatible: missing modifiers have been added and +history substitution has been extended. +.PP +Several of the features described earlier, such as +.B "set -o posix" +and +.B $POSIX_PEDANTIC , +are new in version 1.14. +There is a new shell variable, +.B OSTYPE , +to which Bash assigns a value that identifies the +version of \s-1UNIX\s+1 it's +running on (great for putting architecture-specific binary directories +into the \fB$PATH\fP). +Two variables have been renamed: +.B $HISTCONTROL +replaces +.B $history_control , +and +.B $HOSTFILE +replaces +.B $hostname_completion_file . +In both cases, the old names are accepted for backwards +compatibility. The ksh +.I select +construct, which allows the generation of simple menus, +has been implemented. New capabilities have been added +to existing variables: +.B $auto_resume +can now take values of +.I exact +or +.I substring , +and +.B $HISTCONTROL +understands the value +.I ignoreboth , +which combines the two previously acceptable values. The +.B dirs +builtin has acquired options to print out specific members of the +directory stack. The +.B $nolinks +variable, which forces a physical view of the file system, +has been superseded by the +.B \-P +option to the +.B set +builtin (equivalent to \fBset -o physical\fP); the variable is retained +for backwards compatibility. The version string contained in +.B $BASH_VERSION +now includes an indication of the patch level as well as the +\*Qbuild version\*U. +Some little-used features have +been removed: the +.B bye +synonym for +.B exit +and the +.B $NO_PROMPT_VARS +variable are gone. There is now an organized test suite that can be +run as a regression test when building a new version of Bash. +.PP +The documentation has been thoroughly overhauled: +there is a new manual page on the readline library and the \fIinfo\fP +file has been updated to reflect the current version. +As always, as many bugs as possible have been fixed, although some +surely remain. +.NH 2 +Other Features +.PP +There are a few features that I hope to include in later Bash releases. +Some are based on work already done in other shells. +.PP +In addition to simple variables, a future release of Bash will include +one-dimensional arrays, using the ksh +implementation of arrays as a model. Additions to the ksh syntax, +such as \fIvarname\fP=( ... ) to assign a list of words directly to +an array and a mechanism to allow +the +.B read +builtin to read a list of values directly into an array, would be +desirable. Given those extensions, the ksh +.B "set \-A" +syntax may not be worth supporting (the +.B \-A +option assigns a list of values to an array, but is a rather +peculiar special case). +.PP +Some shells include a means of \fIprogrammable\fP word +completion, where the user specifies on a per-command basis how the +arguments of the command are to be treated when completion is attempted: +as filenames, hostnames, executable files, and so on. The other +aspects of the current Bash implementation could remain as-is; the +existing heuristics would still be valid. Only when completing the +arguments to a simple command would the programmable completion be +in effect. +.PP +It would also be nice to give the user finer-grained +control over which commands are saved onto the history list. One +proposal is for a variable, tentatively named +.B HISTIGNORE , +which would contain a colon-separated list of commands. Lines beginning +with these commands, after the restrictions of +.B $HISTCONTROL +have been applied, would not be placed onto the history list. The +shell pattern-matching capabilities could also be available when +specifying the contents of +.B $HISTIGNORE . +.PP +One thing that newer shells such as +.B wksh +(also known as +.B dtksh ) +provide is a command to dynamically load code +implementing additional builtin commands into a running shell. +This new builtin would take an object file or shared library +implementing the \*Qbody\*U of the +builtin (\fIxxx_builtin()\fP for those familiar with Bash internals) +and a structure containing the name of the new command, the function +to call when the new builtin is invoked (presumably defined in the +shared object specified as an argument), and the documentation to be +printed by the +.B help +command (possibly present in the shared object as well). It would +manage the details of extending the internal table of builtins. +.PP +A few other builtins would also be desirable: two are the POSIX.2 +.B getconf +command, which prints the values of system configuration variables +defined by POSIX.2, and a +.B disown +builtin, which causes a shell running +with job control active to \*Qforget about\*U one or more +background jobs in its internal jobs table. Using +.B getconf , +for example, a user could retrieve a value for +.B $PATH +guaranteed to find all of the POSIX standard utilities, or +find out how long filenames may be in the file system containing +a specified directory. +.PP +There are no implementation timetables for any of these features, nor +are there concrete plans to include them. If anyone has comments on +these proposals, feel free to send me electronic mail. +.NH 1 +Reflections and Lessons Learned +.PP +The lesson that has been repeated most often during Bash +development is that there are dark corners in the Bourne shell, +and people use all of them. In the original description of the +Bourne shell, quoting and the shell grammar are both poorly +specified and incomplete; subsequent descriptions have not helped +much. The grammar presented in Bourne's paper describing +the shell distributed with the Seventh Edition of \s-1UNIX\s+1\(dg +is so far off that it does not allow the command \f(CWwho|wc\fP. +In fact, as Tom Duff states: +.QP +Nobody really knows what the +Bourne shell's grammar is. Even examination of the source code is +little help.\(dd +.FS +\(dgS. R. Bourne, \*QUNIX Time-Sharing System: The UNIX Shell\*U, +\fIBell System Technical Journal\fP, 57(6), July-August, 1978, pp. 1971-1990. +.FE +.FS +\(ddTom Duff, \*QRc \- A Shell for Plan 9 and \s-1UNIX\s+1 systems\*U, +\fIProc. of the Summer 1990 EUUG Conference\fP, London, July, 1990, +pp. 21-33. +.FE +.LP +The POSIX.2 standard includes a \fIyacc\fP grammar that comes close +to capturing the Bourne shell's behavior, but it disallows some +constructs which sh accepts without complaint \- and there are +scripts out there that use them. It took a few versions and +several bug reports before Bash implemented sh-compatible quoting, +and there are still some \*Qlegal\*U sh constructs which Bash flags as +syntax errors. Complete sh compatibility is a tough nut. +.PP +The shell is bigger and slower than I would like, though the current +version is substantially faster than previously. The readline library +could stand a substantial rewrite. A hand-written parser to replace +the current \fIyacc\fP-generated one would probably result in a speedup, +and would solve one glaring problem: the shell could parse +commands in \*Q$(...)\*U constructs +as they are entered, rather than reporting errors when the construct +is expanded. +.PP +As always, there is some chaff to go with the wheat. +Areas of duplicated functionality need to be cleaned +up. There are several cases where Bash treats a variable specially to +enable functionality available another way (\fB$notify\fP vs. +\fBset -o notify\fP and \fB$nolinks\fP vs. \fBset -o physical\fP, for +instance); the special treatment of the variable name should probably +be removed. A few more things could stand removal; the +.B $allow_null_glob_expansion +and +.B $glob_dot_filenames +variables are of particularly questionable value. +The \fB$[...]\fP arithmetic evaluation syntax is redundant now that +the POSIX-mandated \fB$((...))\fP construct has been implemented, +and could be deleted. +It would be nice if the text output by the +.B help +builtin were external to the shell rather than compiled into it. +The behavior enabled by +.B $command_oriented_history , +which causes the shell to attempt to save all lines of a multi-line +command in a single history entry, should be made the default and +the variable removed. +.NH 1 +Availability +.PP +As with all other +GNU software, Bash is available for anonymous FTP from +.I prep.ai.mit.edu:/pub/gnu +and from other GNU software mirror sites. The current version is in +.I bash-1.14.1.tar.gz +in that directory. Use +.I archie +to find the nearest archive site. The +latest version is always available for FTP from +.I bash.CWRU.Edu:/pub/dist. +Bash documentation is available for FTP from +.I bash.CWRU.Edu:/pub/bash. +.PP +The Free Software Foundation sells tapes and CD-ROMs +containing Bash; send electronic mail to +\f(CRgnu@prep.ai.mit.edu\fP or call \f(CR+1-617-876-3296\fP +for more information. +.PP +Bash is also distributed with several versions of \s-1UNIX\s+1-compatible +systems. It is included as /bin/sh and /bin/bash on several Linux +distributions (more about the difference in a moment), and as contributed +software in BSDI's BSD/386* and FreeBSD. +.FS +*BSD/386 is a trademark of Berkeley Software Design, Inc. +.FE +.PP +The Linux distribution deserves special mention. There are two +configurations included in the standard Bash distribution: a +\*Qnormal\*U configuration, in which all of the standard features +are included, and a \*Qminimal\*U configuration, which omits job +control, aliases, history and command line editing, the directory +stack and +.B pushd/popd/dirs, +process substitution, prompt string special character decoding, and the +.I select +construct. This minimal version is designed to be a drop-in replacement +for the traditional \s-1UNIX\s+1 /bin/sh, and is included as the Linux +/bin/sh in several packagings. +.NH 1 +Conclusion +.PP +Bash is a worthy successor to sh. +It is sufficiently portable +to run on nearly every version of \s-1UNIX\s+1 from +4.3 BSD to SVR4.2, and several \s-1UNIX\s+1 workalikes. +It is robust enough to replace sh on most of those systems, +and provides more functionality. It has several thousand regular users, +and their feedback has helped to make it as good as it is today \- a +testament to the benefits of free software. diff --git a/bash-20060316/doc/article.pdf

There +are a number of aspects of UNIX under consideration for +standardization, from the basic system services at the sys- +tem call and C library level to applications and tools to +system administration and management. Each area of stan- +dardization is assigned to a working group in the 1003 +series. + + The POSIX Shell and Utilities standard has been +developed by IEEE Working Group 1003.2 (POSIX.2).|= It con- +centrates on the command interpreter interface and utility +programs commonly executed from the command line or by other +programs. An initial version of the standard has been +approved and published by the IEEE, and work is currently +underway to update it. There are four primary areas of work +in the 1003.2 standard: + +o+ Aspects of the shell's syntax and command language. A + number of special builtins such as _c_d and _e_x_e_c are + being specified as part of the shell, since their func- + tionality usually cannot be implemented by a separate + executable; + +o+ A set of utilities to be called by shell scripts and + applications. Examples are programs like _s_e_d, _t_r, and + _a_w_k. Utilities commonly implemented as shell builtins + are described in this section, such as _t_e_s_t and _k_i_l_l. + An expansion of this section's scope, termed the User + Portability Extension, or UPE, has standardized + interactive programs such as _v_i and _m_a_i_l_x; + +o+ A group of functional interfaces to services provided + by the shell, such as the traditional system() C + library function. There are functions to perform shell + word expansions, perform filename expansion (_g_l_o_b_b_i_n_g), + obtain values of POSIX.2 system configuration vari- + ables, retrieve values of environment variables + (getenv()), _a_n_d _o_t_h_e_r _s_e_r_v_i_c_e_s; + +o+ A suite of "development" utilities such as _c_8_9 (the + POSIX.2 version of _c_c), and _y_a_c_c. + + Bash is concerned with the aspects of the shell's +behavior defined by POSIX.2. The shell command language has +of course been standardized, including the basic flow con- +trol and program execution constructs, I/O redirection and +pipelining, argument handling, variable expansion, and quot- +ing.

Other utilities appear in the sections of +POSIX.2 not devoted to the shell which are commonly (and in +some cases must be) implemented as builtin commands, such as +_r_e_a_d and _t_e_s_t. POSIX.2 also specifies aspects of the +shell's interactive behavior as part of the UPE, including +job control and command line editing. Interestingly enough, +only _v_i-style line editing commands have been standardized; +_e_m_a_c_s editing commands were left out due to objections. + + While POSIX.2 includes much of what the shell has trad- +itionally provided, some important things have been omitted +as being "beyond its scope." There is, for instance, no +mention of a difference between a _l_o_g_i_n shell and any other +interactive shell (since POSIX.2 does not specify a login +program). No fixed startup files are defined, either - the +standard does not mention ._p_r_o_f_i_l_e. + +_3. _B_a_s_i_c _B_a_s_h _f_e_a_t_u_r_e_s + + Since the Bourne shell provides Bash with most of its +philosophical underpinnings, Bash inherits most of its +features and functionality from sh. Bash implements all of +the traditional sh flow control constructs (_f_o_r, _i_f, _w_h_i_l_e, +etc.). All of the Bourne shell builtins, including those +not specified in the POSIX.2 standard, appear in Bash. +Shell _f_u_n_c_t_i_o_n_s, introduced in the SVR2 version of the +Bourne shell, are similar to shell scripts, but are defined +using a special syntax and are executed in the same process +as the calling shell. Bash has shell functions which behave +in a fashion upward-compatible with sh functions. There are +certain shell variables that Bash interprets in the same way +as sh, such as _P_S_1, _I_F_S, and _P_A_T_H. Bash implements essen- +tially the same grammar, parameter and variable expansion +semantics, redirection, and quoting as the Bourne shell. +Where differences appear between the POSIX.2 standard and +traditional sh behavior, Bash follows POSIX. + + The Korn Shell (ksh) is a descendent of the Bourne +shell written at AT&T Bell Laboratories by David Korn|-. It +provides a number of useful features that POSIX and Bash +have adopted. Many of the interactive facilities in POSIX.2 +have their roots in the ksh: for example, the POSIX and ksh +job control facilities are nearly identical. Bash includes +features from the Korn Shell for both interactive use and +shell programming. For programming, Bash provides variables +such as _R_A_N_D_O_M and _R_E_P_L_Y, the _t_y_p_e_s_e_t builtin, the ability +to remove substrings from variables based on patterns, and +shell arithmetic. _R_A_N_D_O_M expands to a random number each +time it is referenced; assigning a value to _R_A_N_D_O_M seeds the +_________________________ +|-Morris Bolsky and David Korn, _T_h_e _K_o_r_n_S_h_e_l_l _C_o_m_m_a_n_d +_a_n_d _P_r_o_g_r_a_m_m_i_n_g _L_a_n_g_u_a_g_e, Prentice Hall, 1989. + + + + + October 28, 1994 + + + + + + - 4 - + + +random number generator. _R_E_P_L_Y is the default variable used +by the _r_e_a_d builtin when no variable names are supplied as +arguments. The _t_y_p_e_s_e_t builtin is used to define variables +and give them attributes such as readonly. Bash arithmetic +allows the evaluation of an expression and the substitution +of the result. Shell variables may be used as operands, and +the result of an expression may be assigned to a variable. +Nearly all of the operators from the C language are avail- +able, with the same precedence rules: +9 $ echo $((3 + 5 * 32)) + 163 +9 +For interactive use, Bash implements ksh-style aliases and +builtins such as _f_c (discussed below) and _j_o_b_s. Bash +aliases allow a string to be substituted for a command name. +They can be used to create a mnemonic for a UNIX command +name (alias del=rm), to expand a single word to a complex +command (alias news='xterm -g 80x45 -title trn -e trn -e -S1 +-N &'), or to ensure that a command is invoked with a basic +set of options (alias ls="/bin/ls -F"). + + The C shell (csh)|-, originally written by Bill Joy +while at Berkeley, is widely used and quite popular for its +interactive facilities. Bash includes a csh-compatible his- +tory expansion mechanism ("! history"), brace expansion, +access to a stack of directories via the _p_u_s_h_d, _p_o_p_d, and +_d_i_r_s builtins, and tilde expansion, to generate users' home +directories. Tilde expansion has also been adopted by both +the Korn Shell and POSIX.2. + + There were certain areas in which POSIX.2 felt stan- +dardization was necessary, but no existing implementation +provided the proper behavior. The working group invented +and standardized functionality in these areas, which Bash +implements. The _c_o_m_m_a_n_d builtin was invented so that shell +functions could be written to replace builtins; it makes the +capabilities of the builtin available to the function. The +reserved word "!" was added to negate the return value of a +command or pipeline; it was nearly impossible to express "if +not x" cleanly using the sh language. There exist multiple +incompatible implementations of the _t_e_s_t builtin, which +tests files for type and other attributes and performs +arithmetic and string comparisons. POSIX considered none of +these correct, so the standard behavior was specified in +terms of the number of arguments to the command. POSIX.2 +dictates exactly what will happen when four or fewer argu- +ments are given to _t_e_s_t, and leaves the behavior undefined +when more arguments are supplied.

The majority of these are due to the POSIX standard, +but some are the result of Bash adopting features from other +shells. For instance, Bash includes the new "!" reserved +word, the _c_o_m_m_a_n_d builtin, the ability of the _r_e_a_d builtin +to correctly return a line ending with a backslash, symbolic +arguments to the _u_m_a_s_k builtin, variable substring removal, +a way to get the length of a variable, and the new algorithm +for the _t_e_s_t builtin from the POSIX.2 standard, none of +which appear in sh. + + Bash also implements the "$(...)" command substitution +syntax, which supersedes the sh `...` construct. The +"$(...)" construct expands to the output of the command con- +tained within the parentheses, with trailing newlines +removed. The sh syntax is accepted for backwards compati- +bility, but the "$(...)" form is preferred because its quot- +ing rules are much simpler and it is easier to nest. + + The Bourne shell does not provide such features as +brace expansion, the ability to define a variable and a +function with the same name, local variables in shell func- +tions, the ability to enable and disable individual builtins +or write a function to replace a builtin, or a means to +export a shell function to a child process. + + Bash has closed a long-standing shell security hole by +not using the $_I_F_S variable to split each word read by the +shell, but splitting only the results of expansion (ksh and +the 4.4 BSD sh have fixed this as well). Useful behavior +such as a means to abort execution of a script read with the +"." command using the return builtin or automatically +exporting variables in the shell's environment to children +is also not present in the Bourne shell. Bash provides a +much more powerful environment for both interactive use and +programming. + +_4. _B_a_s_h-_s_p_e_c_i_f_i_c _F_e_a_t_u_r_e_s + + This section details a few of the features which make +Bash unique. Most of them provide improved interactive use, +but a few programming improvements are present as well. +Full descriptions of these features can be found in the Bash +documentation. + +_4._1. _S_t_a_r_t_u_p _F_i_l_e_s + + Bash executes startup files differently than other +shells. The Bash behavior is a compromise between the csh + + + + October 28, 1994 + + + + + + - 6 - + + +principle of startup files with fixed names executed for +each shell and the sh "minimalist" behavior. An interactive +instance of Bash started as a login shell reads and executes +~/._b_a_s_h__p_r_o_f_i_l_e (the file .bash_profile in the user's home +directory), if it exists. An interactive non-login shell +reads and executes ~/._b_a_s_h_r_c. A non-interactive shell (one +begun to execute a shell script, for example) reads no fixed +startup file, but uses the value of the variable $_E_N_V, if +set, as the name of a startup file. The ksh practice of +reading $_E_N_V for every shell, with the accompanying diffi- +culty of defining the proper variables and functions for +interactive and non-interactive shells or having the file +read only for interactive shells, was considered too com- +plex. Ease of use won out here. Interestingly, the next +release of ksh will change to reading $_E_N_V only for interac- +tive shells. + +_4._2. _N_e_w _B_u_i_l_t_i_n _C_o_m_m_a_n_d_s + + There are a few builtins which are new or have been +extended in Bash. The _e_n_a_b_l_e builtin allows builtin com- +mands to be turned on and off arbitrarily. To use the ver- +sion of _e_c_h_o found in a user's search path rather than the +Bash builtin, enable -n echo suffices. The _h_e_l_p builtin +provides quick synopses of the shell facilities without +requiring access to a manual page. _B_u_i_l_t_i_n is similar to +_c_o_m_m_a_n_d in that it bypasses shell functions and directly +executes builtin commands. Access to a csh-style stack of +directories is provided via the _p_u_s_h_d, _p_o_p_d, and _d_i_r_s buil- +tins. _P_u_s_h_d and _p_o_p_d insert and remove directories from the +stack, respectively, and _d_i_r_s lists the stack contents. On +systems that allow fine-grained control of resources, the +_u_l_i_m_i_t builtin can be used to tune these settings. _U_l_i_m_i_t +allows a user to control, among other things, whether core +dumps are to be generated, how much memory the shell or a +child process is allowed to allocate, and how large a file +created by a child process can grow. The _s_u_s_p_e_n_d command +will stop the shell process when job control is active; most +other shells do not allow themselves to be stopped like +that. _T_y_p_e, the Bash answer to _w_h_i_c_h and _w_h_e_n_c_e, shows what +will happen when a word is typed as a command: +9 $ type export + export is a shell builtin + $ type -t export + builtin + $ type bash + bash is /bin/bash + $ type cd + cd is a function + cd () + { + builtin cd ${1+"$@"} && xtitle $HOST: $PWD + } +9 + + + October 28, 1994 + + + + + + - 7 - + + +Various modes tell what a command word is (reserved word, +alias, function, builtin, or file) or which version of a +command will be executed based on a user's search path. +Some of this functionality has been adopted by POSIX.2 and +folded into the _c_o_m_m_a_n_d utility. + +_4._3. _E_d_i_t_i_n_g _a_n_d _C_o_m_p_l_e_t_i_o_n + + One area in which Bash shines is command line editing. +Bash uses the _r_e_a_d_l_i_n_e library to read and edit lines when +interactive. Readline is a powerful and flexible input +facility that a user can configure to individual tastes. It +allows lines to be edited using either emacs or vi commands, +where those commands are appropriate. The full capability +of emacs is not present - there is no way to execute a named +command with M-x, for instance - but the existing commands +are more than adequate. The vi mode is compliant with the +command line editing standardized by POSIX.2. + + Readline is fully customizable. In addition to the +basic commands and key bindings, the library allows users to +define additional key bindings using a startup file. The +_i_n_p_u_t_r_c file, which defaults to the file ~/._i_n_p_u_t_r_c, is read +each time readline initializes, permitting users to maintain +a consistent interface across a set of programs. Readline +includes an extensible interface, so each program using the +library can add its own bindable commands and program- +specific key bindings. Bash uses this facility to add bind- +ings that perform history expansion or shell word expansions +on the current input line. + + Readline interprets a number of variables which further +tune its behavior. Variables exist to control whether or +not eight-bit characters are directly read as input or con- +verted to meta-prefixed key sequences (a meta-prefixed key +sequence consists of the character with the eighth bit +zeroed, preceded by the _m_e_t_a-_p_r_e_f_i_x character, usually +escape, which selects an alternate keymap), to decide +whether to output characters with the eighth bit set +directly or as a meta-prefixed key sequence, whether or not +to wrap to a new screen line when a line being edited is +longer than the screen width, the keymap to which subsequent +key bindings should apply, or even what happens when read- +line wants to ring the terminal's bell. All of these vari- +ables can be set in the inputrc file. + + The startup file understands a set of C preprocessor- +like conditional constructs which allow variables or key +bindings to be assigned based on the application using read- +line, the terminal currently being used, or the editing +mode. Users can add program-specific bindings to make their +lives easier: I have bindings that let me edit the value of +$_P_A_T_H and double-quote the current or previous word: +9 # Macros that are convenient for shell interaction + + +9 October 28, 1994 + + + + + + - 8 - + + + $if Bash + # edit the path + "\C-xp": "PATH=${PATH}\e\C-e\C-a\ef\C-f" + # prepare to type a quoted word -- insert open and close double + # quotes and move to just after the open quote + "\C-x\"": "\"\"\C-b" + # Quote the current or previous word + "\C-xq": "\eb\"\ef\"" + $endif +9 +There is a readline command to re-read the file, so users +can edit the file, change some bindings, and begin to use +them almost immediately. + + Bash implements the _b_i_n_d builtin for more dyamic con- +trol of readline than the startup file permits. _B_i_n_d is +used in several ways. In _l_i_s_t mode, it can display the +current key bindings, list all the readline editing direc- +tives available for binding, list which keys invoke a given +directive, or output the current set of key bindings in a +format that can be incorporated directly into an inputrc +file. In _b_a_t_c_h mode, it reads a series of key bindings +directly from a file and passes them to readline. In its +most common usage, _b_i_n_d takes a single string and passes it +directly to readline, which interprets the line as if it had +just been read from the inputrc file. Both key bindings and +variable assignments may appear in the string given to _b_i_n_d. + + The readline library also provides an interface for +_w_o_r_d _c_o_m_p_l_e_t_i_o_n. When the _c_o_m_p_l_e_t_i_o_n character (usually +TAB) is typed, readline looks at the word currently being +entered and computes the set of filenames of which the +current word is a valid prefix. If there is only one possi- +ble completion, the rest of the characters are inserted +directly, otherwise the common prefix of the set of +filenames is added to the current word. A second TAB char- +acter entered immediately after a non-unique completion +causes readline to list the possible completions; there is +an option to have the list displayed immediately. Readline +provides hooks so that applications can provide specific +types of completion before the default filename completion +is attempted. This is quite flexible, though it is not com- +pletely user-programmable. Bash, for example, can complete +filenames, command names (including aliases, builtins, shell +reserved words, shell functions, and executables found in +the file system), shell variables, usernames, and hostnames. +It uses a set of heuristics that, while not perfect, is gen- +erally quite good at determining what type of completion to +attempt. + +_4._4. _H_i_s_t_o_r_y + + Access to the list of commands previously entered (the +_c_o_m_m_a_n_d _h_i_s_t_o_r_y) is provided jointly by Bash and the + + +9 October 28, 1994 + + + + + + - 9 - + + +readline library. Bash provides variables ($HISTFILE, +$HISTSIZE, and $HISTCONTROL) and the _h_i_s_t_o_r_y and _f_c builtins +to manipulate the history list. The value of $_H_I_S_T_F_I_L_E +specifes the file where Bash writes the command history on +exit and reads it on startup. $_H_I_S_T_S_I_Z_E is used to limit +the number of commands saved in the history. $_H_I_S_T_C_O_N_T_R_O_L +provides a crude form of control over which commands are +saved on the history list: a value of _i_g_n_o_r_e_s_p_a_c_e means to +not save commands which begin with a space; a value of +_i_g_n_o_r_e_d_u_p_s means to not save commands identical to the last +command saved. $HISTCONTROL was named $history_control in +earlier versions of Bash; the old name is still accepted for +backwards compatibility. The _h_i_s_t_o_r_y command can read or +write files containing the history list and display the +current list contents. The _f_c builtin, adopted from POSIX.2 +and the Korn Shell, allows display and re-execution, with +optional editing, of commands from the history list. The +readline library offers a set of commands to search the his- +tory list for a portion of the current input line or a +string typed by the user. Finally, the _h_i_s_t_o_r_y library, +generally incorporated directly into the readline library, +implements a facility for history recall, expansion, and +re-execution of previous commands very similar to csh ("bang +history", so called because the exclamation point introduces +a history substitution): +9 $ echo a b c d e + a b c d e + $ !! f g h i + echo a b c d e f g h i + a b c d e f g h i + $ !-2 + echo a b c d e + a b c d e + $ echo !-2:1-4 + echo a b c d + a b c d +9 +The command history is only saved when the shell is interac- +tive, so it is not available for use by shell scripts. + +_4._5. _N_e_w _S_h_e_l_l _V_a_r_i_a_b_l_e_s + + There are a number of convenience variables that Bash +interprets to make life easier. These include _F_I_G_N_O_R_E, +which is a set of filename suffixes identifying files to +exclude when completing filenames; _H_O_S_T_T_Y_P_E, which is +automatically set to a string describing the type of +hardware on which Bash is currently executing; +_c_o_m_m_a_n_d__o_r_i_e_n_t_e_d__h_i_s_t_o_r_y, which directs Bash to save all +lines of a multiple-line command such as a _w_h_i_l_e or _f_o_r loop +in a single history entry, allowing easy re-editing; and +_I_G_N_O_R_E_E_O_F, whose value indicates the number of consecutive +EOF characters that an interactive shell will read before + + + + October 28, 1994 + + + + + + - 10 - + + +exiting - an easy way to keep yourself from being logged out +accidentally. The _a_u_t_o__r_e_s_u_m_e variable alters the way the +shell treats simple command names: if job control is active, +and this variable is set, single-word simple commands +without redirections cause the shell to first look for and +restart a suspended job with that name before starting a new +process. + +_4._6. _B_r_a_c_e _E_x_p_a_n_s_i_o_n + + Since sh offers no convenient way to generate arbitrary +strings that share a common prefix or suffix (filename +expansion requires that the filenames exist), Bash imple- +ments _b_r_a_c_e _e_x_p_a_n_s_i_o_n, a capability picked up from csh. +Brace expansion is similar to filename expansion, but the +strings generated need not correspond to existing files. A +brace expression consists of an optional _p_r_e_a_m_b_l_e, followed +by a pair of braces enclosing a series of comma-separated +strings, and an optional _p_o_s_t_a_m_b_l_e. The preamble is +prepended to each string within the braces, and the postam- +ble is then appended to each resulting string: +9 $ echo a{d,c,b}e + ade ace abe +9 +As this example demonstrates, the results of brace expansion +are not sorted, as they are by filename expansion. + +_4._7. _P_r_o_c_e_s_s _S_u_b_s_t_i_t_u_t_i_o_n + + On systems that can support it, Bash provides a facil- +ity known as _p_r_o_c_e_s_s _s_u_b_s_t_i_t_u_t_i_o_n. Process substitution is +similar to command substitution in that its specification +includes a command to execute, but the shell does not col- +lect the command's output and insert it into the command +line. Rather, Bash opens a pipe to the command, which is +run in the background. The shell uses named pipes (FIFOs) +or the /_d_e_v/_f_d method of naming open files to expand the +process substitution to a filename which connects to the +pipe when opened. This filename becomes the result of the +expansion. Process substitution can be used to compare the +outputs of two different versions of an application as part +of a regression test: +9 $ cmp <(old_prog) <(new_prog) +9 +_4._8. _P_r_o_m_p_t _C_u_s_t_o_m_i_z_a_t_i_o_n + + One of the more popular interactive features that Bash +provides is the ability to customize the prompt. Both $_P_S_1 +and $_P_S_2, the primary and secondary prompts, are expanded +before being displayed. Parameter and variable expansion is +performed when the prompt string is expanded, so any shell +variable can be put into the prompt (e.g., $_S_H_L_V_L, which + + + + October 28, 1994 + + + + + + - 11 - + + +indicates how deeply the current shell is nested). Bash +specially interprets characters in the prompt string pre- +ceded by a backslash. Some of these backslash escapes are +replaced with the current time, the date, the current work- +ing directory, the username, and the command number or his- +tory number of the command being entered. There is even a +backslash escape to cause the shell to change its prompt +when running as root after an _s_u. Before printing each pri- +mary prompt, Bash expands the variable $_P_R_O_M_P_T__C_O_M_M_A_N_D and, +if it has a value, executes the expanded value as a command, +allowing additional prompt customization. For example, this +assignment causes the current user, the current host, the +time, the last component of the current working directory, +the level of shell nesting, and the history number of the +current command to be embedded into the primary prompt: +9 $ PS1='\u@\h [\t] \W($SHLVL:\!)\$ ' + chet@odin [21:03:44] documentation(2:636)$ cd .. + chet@odin [21:03:54] src(2:637)$ +9 +The string being assigned is surrounded by single quotes so +that if it is exported, the value of $_S_H_L_V_L will be updated +by a child shell: +9 chet@odin [21:17:35] src(2:638)$ export PS1 + chet@odin [21:17:40] src(2:639)$ bash + chet@odin [21:17:46] src(3:696)$ +9 +The \$ escape is displayed as "$" when running as a normal +user, but as "#" when running as root. + +_4._9. _F_i_l_e _S_y_s_t_e_m _V_i_e_w_s + + Since Berkeley introduced symbolic links in 4.2 BSD, +one of their most annoying properties has been the "warping" +to a completely different area of the file system when using +_c_d, and the resultant non-intuitive behavior of "cd ..". +The UNIX kernel treats symbolic links _p_h_y_s_i_c_a_l_l_y. When the +kernel is translating a pathname in which one component is a +symbolic link, it replaces all or part of the pathname while +processing the link. If the contents of the symbolic link +begin with a slash, the kernel replaces the pathname +entirely; if not, the link contents replace the current com- +ponent. In either case, the symbolic link is visible. If +the link value is an absolute pathname, the user finds him- +self in a completely different part of the file system. + + Bash provides a _l_o_g_i_c_a_l view of the file system. In +this default mode, command and filename completion and buil- +tin commands such as _c_d and _p_u_s_h_d which change the current +working directory transparently follow symbolic links as if +they were directories. The $_P_W_D variable, which holds the +shell's idea of the current working directory, depends on +the path used to reach the directory rather than its + + + + October 28, 1994 + + + + + + - 12 - + + +physical location in the local file system hierarchy. For +example: +9 $ cd /usr/local/bin + $ echo $PWD + /usr/local/bin + $ pwd + /usr/local/bin + $ /bin/pwd + /net/share/sun4/local/bin + $ cd .. + $ pwd + /usr/local + $ /bin/pwd + /net/share/sun4/local + $ cd .. + $ pwd + /usr + $ /bin/pwd + /usr +9 +One problem with this, of course, arises when programs that +do not understand the shell's logical notion of the file +system interpret ".." differently. This generally happens +when Bash completes filenames containing ".." according to a +logical hierarchy which does not correspond to their physi- +cal location. For users who find this troublesome, a +corresponding _p_h_y_s_i_c_a_l view of the file system is available: +9 $ cd /usr/local/bin + $ pwd + /usr/local/bin + $ set -o physical + $ pwd + /net/share/sun4/local/bin +9 +_4._1_0. _I_n_t_e_r_n_a_t_i_o_n_a_l_i_z_a_t_i_o_n + + One of the most significant improvements in version +1.13 of Bash was the change to "eight-bit cleanliness". +Previous versions used the eighth bit of characters to mark +whether or not they were quoted when performing word expan- +sions. While this did not affect the majority of users, +most of whom used only seven-bit ASCII characters, some +found it confining. Beginning with version 1.13, Bash +implemented a different quoting mechanism that did not alter +the eighth bit of characters. This allowed Bash to manipu- +late files with "odd" characters in their names, but did +nothing to help users enter those names, so version 1.13 +introduced changes to readline that made it eight-bit clean +as well. Options exist that force readline to attach no +special significance to characters with the eighth bit set +(the default behavior is to convert these characters to +meta-prefixed key sequences) and to output these characters + + + + October 28, 1994 + + + + + + - 13 - + + +without conversion to meta-prefixed sequences. These +changes, along with the expansion of keymaps to a full eight +bits, enable readline to work with most of the ISO-8859 fam- +ily of character sets, used by many European countries. + +_4._1_1. _P_O_S_I_X _M_o_d_e + + Although Bash is intended to be POSIX.2 conformant, +there are areas in which the default behavior is not compa- +tible with the standard. For users who wish to operate in a +strict POSIX.2 environment, Bash implements a _P_O_S_I_X _m_o_d_e. +When this mode is active, Bash modifies its default opera- +tion where it differs from POSIX.2 to match the standard. +POSIX mode is entered when Bash is started with the -_p_o_s_i_x +option. This feature is also available as an option to the +set builtin, set -o posix. For compatibility with other GNU +software that attempts to be POSIX.2 compliant, Bash also +enters POSIX mode if the variable $_P_O_S_I_X_L_Y__C_O_R_R_E_C_T is set +when Bash is started or assigned a value during execution. +$_P_O_S_I_X__P_E_D_A_N_T_I_C is accepted as well, to be compatible with +some older GNU utilities. When Bash is started in POSIX +mode, for example, it sources the file named by the value of +$_E_N_V rather than the "normal" startup files, and does not +allow reserved words to be aliased. + +_5. _N_e_w _F_e_a_t_u_r_e_s _a_n_d _F_u_t_u_r_e _P_l_a_n_s + + There are several features introduced in the current +version of Bash, version 1.14, and a number under considera- +tion for future releases. This section will briefly detail +the new features in version 1.14 and describe several +features that may appear in later versions. + +_5._1. _N_e_w _F_e_a_t_u_r_e_s _i_n _B_a_s_h-_1._1_4 + + The new features available in Bash-1.14 answer several +of the most common requests for enhancements. Most notably, +there is a mechanism for including non-visible character +sequences in prompts, such as those which cause a terminal +to print characters in different colors or in standout mode. +There was nothing preventing the use of these sequences in +earlier versions, but the readline redisplay algorithm +assumed each character occupied physical screen space and +would wrap lines prematurely. + + Readline has a few new variables, several new bindable +commands, and some additional emacs mode default key bind- +ings. A new history search mode has been implemented: in +this mode, readline searches the history for lines beginning +with the characters between the beginning of the current +line and the cursor. The existing readline incremental +search commands no longer match identical lines more than +once. Filename completion now expands variables in direc- +tory names. The history expansion facilities are now nearly + + + + October 28, 1994 + + + + + + - 14 - + + +completely csh-compatible: missing modifiers have been added +and history substitution has been extended. + + Several of the features described earlier, such as _s_e_t +-_o _p_o_s_i_x and $_P_O_S_I_X__P_E_D_A_N_T_I_C, are new in version 1.14. +There is a new shell variable, _O_S_T_Y_P_E, to which Bash assigns +a value that identifies the version of UNIX it's running on +(great for putting architecture-specific binary directories +into the $PATH). Two variables have been renamed: $_H_I_S_T_C_O_N_- +_T_R_O_L replaces $_h_i_s_t_o_r_y__c_o_n_t_r_o_l, and $_H_O_S_T_F_I_L_E replaces +$_h_o_s_t_n_a_m_e__c_o_m_p_l_e_t_i_o_n__f_i_l_e. In both cases, the old names are +accepted for backwards compatibility. The ksh _s_e_l_e_c_t con- +struct, which allows the generation of simple menus, has +been implemented. New capabilities have been added to +existing variables: $_a_u_t_o__r_e_s_u_m_e can now take values of +_e_x_a_c_t or _s_u_b_s_t_r_i_n_g, and $_H_I_S_T_C_O_N_T_R_O_L understands the value +_i_g_n_o_r_e_b_o_t_h, which combines the two previously acceptable +values. The _d_i_r_s builtin has acquired options to print out +specific members of the directory stack. The $_n_o_l_i_n_k_s vari- +able, which forces a physical view of the file system, has +been superseded by the -_P option to the _s_e_t builtin +(equivalent to set -o physical); the variable is retained +for backwards compatibility. The version string contained +in $_B_A_S_H__V_E_R_S_I_O_N now includes an indication of the patch +level as well as the "build version". Some little-used +features have been removed: the _b_y_e synonym for _e_x_i_t and +the $_N_O__P_R_O_M_P_T__V_A_R_S variable are gone. There is now an +organized test suite that can be run as a regression test +when building a new version of Bash. + + The documentation has been thoroughly overhauled: there +is a new manual page on the readline library and the _i_n_f_o +file has been updated to reflect the current version. As +always, as many bugs as possible have been fixed, although +some surely remain. + +_5._2. _O_t_h_e_r _F_e_a_t_u_r_e_s + + There are a few features that I hope to include in +later Bash releases. Some are based on work already done in +other shells. + + In addition to simple variables, a future release of +Bash will include one-dimensional arrays, using the ksh +implementation of arrays as a model. Additions to the ksh +syntax, such as _v_a_r_n_a_m_e=( ... ) to assign a list of words +directly to an array and a mechanism to allow the _r_e_a_d buil- +tin to read a list of values directly into an array, would +be desirable. Given those extensions, the ksh _s_e_t -_A syntax +may not be worth supporting (the -_A option assigns a list of +values to an array, but is a rather peculiar special case). + + Some shells include a means of _p_r_o_g_r_a_m_m_a_b_l_e word com- +pletion, where the user specifies on a per-command basis how + + + + October 28, 1994 + + + + + + - 15 - + + +the arguments of the command are to be treated when comple- +tion is attempted: as filenames, hostnames, executable +files, and so on. The other aspects of the current Bash +implementation could remain as-is; the existing heuristics +would still be valid. Only when completing the arguments to +a simple command would the programmable completion be in +effect. + + It would also be nice to give the user finer-grained +control over which commands are saved onto the history list. +One proposal is for a variable, tentatively named _H_I_S_T_I_G_- +_N_O_R_E, which would contain a colon-separated list of com- +mands. Lines beginning with these commands, after the res- +trictions of $_H_I_S_T_C_O_N_T_R_O_L have been applied, would not be +placed onto the history list. The shell pattern-matching +capabilities could also be available when specifying the +contents of $_H_I_S_T_I_G_N_O_R_E. + + One thing that newer shells such as _w_k_s_h (also known as +_d_t_k_s_h) provide is a command to dynamically load code imple- +menting additional builtin commands into a running shell. +This new builtin would take an object file or shared library +implementing the "body" of the builtin (_x_x_x__b_u_i_l_t_i_n() for +those familiar with Bash internals) and a structure contain- +ing the name of the new command, the function to call when +the new builtin is invoked (presumably defined in the shared +object specified as an argument), and the documentation to +be printed by the _h_e_l_p command (possibly present in the +shared object as well). It would manage the details of +extending the internal table of builtins. + + A few other builtins would also be desirable: two are +the POSIX.2 _g_e_t_c_o_n_f command, which prints the values of sys- +tem configuration variables defined by POSIX.2, and a _d_i_s_o_w_n +builtin, which causes a shell running with job control +active to "forget about" one or more background jobs in its +internal jobs table. Using _g_e_t_c_o_n_f, for example, a user +could retrieve a value for $_P_A_T_H guaranteed to find all of +the POSIX standard utilities, or find out how long filenames +may be in the file system containing a specified directory. + + There are no implementation timetables for any of these +features, nor are there concrete plans to include them. If +anyone has comments on these proposals, feel free to send me +electronic mail. + +_6. _R_e_f_l_e_c_t_i_o_n_s _a_n_d _L_e_s_s_o_n_s _L_e_a_r_n_e_d + + The lesson that has been repeated most often during +Bash development is that there are dark corners in the +Bourne shell, and people use all of them. In the original +description of the Bourne shell, quoting and the shell gram- +mar are both poorly specified and incomplete; subsequent +descriptions have not helped much. The grammar presented in + + + + October 28, 1994 + + + + + + - 16 - + + +Bourne's paper describing the shell distributed with the +Seventh Edition of UNIX|- is so far off that it does not +allow the command who|wc. In fact, as Tom Duff states: + + Nobody really knows what the Bourne shell's gram- + mar is. Even examination of the source code is + little help.|= + +The POSIX.2 standard includes a _y_a_c_c grammar that comes +close to capturing the Bourne shell's behavior, but it +disallows some constructs which sh accepts without complaint +- and there are scripts out there that use them. It took a +few versions and several bug reports before Bash implemented +sh-compatible quoting, and there are still some "legal" sh +constructs which Bash flags as syntax errors. Complete sh +compatibility is a tough nut. + + The shell is bigger and slower than I would like, +though the current version is substantially faster than pre- +viously. The readline library could stand a substantial +rewrite. A hand-written parser to replace the current +_y_a_c_c-generated one would probably result in a speedup, and +would solve one glaring problem: the shell could parse com- +mands in "$(...)" constructs as they are entered, rather +than reporting errors when the construct is expanded. + + As always, there is some chaff to go with the wheat. +Areas of duplicated functionality need to be cleaned up. +There are several cases where Bash treats a variable spe- +cially to enable functionality available another way +($notify vs. set -o notify and $nolinks vs. set -o physi- +cal, for instance); the special treatment of the variable +name should probably be removed. A few more things could +stand removal; the $_a_l_l_o_w__n_u_l_l__g_l_o_b__e_x_p_a_n_s_i_o_n and +$_g_l_o_b__d_o_t__f_i_l_e_n_a_m_e_s variables are of particularly question- +able value. The $[...] arithmetic evaluation syntax is +redundant now that the POSIX-mandated $((...)) construct has +been implemented, and could be deleted. It would be nice if +the text output by the _h_e_l_p builtin were external to the +shell rather than compiled into it. The behavior enabled by +$_c_o_m_m_a_n_d__o_r_i_e_n_t_e_d__h_i_s_t_o_r_y, which causes the shell to attempt +to save all lines of a multi-line command in a single his- +tory entry, should be made the default and the variable +removed. + + +_________________________ +|-S.

PPSS11 is set and $$-- includes ii if bbaasshh is interactive, allowing + a shell script or a startup file to test this state. + + The following paragraphs describe how bbaasshh executes its startup files. + If any of the files exist but cannot be read, bbaasshh reports an error. + Tildes are expanded in file names as described below under TTiillddee EExxppaann-- + ssiioonn in the EEXXPPAANNSSIIOONN section. + + When bbaasshh is invoked as an interactive login shell, or as a non-inter- + active shell with the ----llooggiinn option, it first reads and executes com- + mands from the file _/_e_t_c_/_p_r_o_f_i_l_e, if that file exists. After reading + that file, it looks for _~_/_._b_a_s_h___p_r_o_f_i_l_e, _~_/_._b_a_s_h___l_o_g_i_n, and _~_/_._p_r_o_f_i_l_e, + in that order, and reads and executes commands from the first one that + exists and is readable.

This + may be inhibited by using the ----nnoorrcc option. The ----rrccffiillee _f_i_l_e option + will force bbaasshh to read and execute commands from _f_i_l_e instead of + _~_/_._b_a_s_h_r_c. + + When bbaasshh is started non-interactively, to run a shell script, for + example, it looks for the variable BBAASSHH__EENNVV in the environment, expands + its value if it appears there, and uses the expanded value as the name + of a file to read and execute. BBaasshh behaves as if the following com- + mand were executed: + if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi + but the value of the PPAATTHH variable is not used to search for the file + name. + + If bbaasshh is invoked with the name sshh, it tries to mimic the startup + behavior of historical versions of sshh as closely as possible, while + conforming to the POSIX standard as well. When invoked as an interac- + tive login shell, or a non-interactive shell with the ----llooggiinn option, + it first attempts to read and execute commands from _/_e_t_c_/_p_r_o_f_i_l_e and + _~_/_._p_r_o_f_i_l_e, in that order. The ----nnoopprrooffiillee option may be used to + inhibit this behavior. When invoked as an interactive shell with the + name sshh, bbaasshh looks for the variable EENNVV, expands its value if it is + defined, and uses the expanded value as the name of a file to read and + execute. Since a shell invoked as sshh does not attempt to read and exe- + cute commands from any other startup files, the ----rrccffiillee option has no + effect. A non-interactive shell invoked with the name sshh does not + attempt to read any other startup files. When invoked as sshh, bbaasshh + enters _p_o_s_i_x mode after the startup files are read. + + When bbaasshh is started in _p_o_s_i_x mode, as with the ----ppoossiixx command line + option, it follows the POSIX standard for startup files. In this mode, + interactive shells expand the EENNVV variable and commands are read and + executed from the file whose name is the expanded value. No other + startup files are read. + + BBaasshh attempts to determine when it is being run by the remote shell + daemon, usually _r_s_h_d. If bbaasshh determines it is being run by _r_s_h_d, it + reads and executes commands from _~_/_._b_a_s_h_r_c, if that file exists and is + readable. It will not do this if invoked as sshh. The ----nnoorrcc option may + be used to inhibit this behavior, and the ----rrccffiillee option may be used + to force another file to be read, but _r_s_h_d does not generally invoke + the shell with those options or allow them to be specified. + + If the shell is started with the effective user (group) id not equal to + the real user (group) id, and the --pp option is not supplied, no startup + files are read, shell functions are not inherited from the environment, + the SSHHEELLLLOOPPTTSS variable, if it appears in the environment, is ignored, + and the effective user id is set to the real user id. If the --pp option + is supplied at invocation, the startup behavior is the same, but the + effective user id is not reset. + +DDEEFFIINNIITTIIOONNSS + The following definitions are used throughout the rest of this docu- + ment. + bbllaannkk A space or tab. + wwoorrdd A sequence of characters considered as a single unit by the + shell.

This connection is performed before any redirec- + tions specified by the command (see RREEDDIIRREECCTTIIOONN below). + + The return status of a pipeline is the exit status of the last command, + unless the ppiippeeffaaiill option is enabled. If ppiippeeffaaiill is enabled, the + pipeline's return status is the value of the last (rightmost) command + to exit with a non-zero status, or zero if all commands exit success- + fully. If the reserved word !! precedes a pipeline, the exit status of + that pipeline is the logical negation of the exit status as described + above. The shell waits for all commands in the pipeline to terminate + before returning a value. + + If the ttiimmee reserved word precedes a pipeline, the elapsed as well as + user and system time consumed by its execution are reported when the + pipeline terminates. The --pp option changes the output format to that + specified by POSIX. The TTIIMMEEFFOORRMMAATT variable may be set to a format + string that specifies how the timing information should be displayed; + see the description of TTIIMMEEFFOORRMMAATT under SShheellll VVaarriiaabblleess below. + + Each command in a pipeline is executed as a separate process (i.e., in + a subshell). + + LLiissttss + A _l_i_s_t is a sequence of one or more pipelines separated by one of the + operators ;;, &&, &&&&, or ||||, and optionally terminated by one of ;;, &&, or + <>. + + Of these list operators, &&&& and |||| have equal precedence, followed by ;; + and &&,, which have equal precedence. + + A sequence of one or more newlines may appear in a _l_i_s_t instead of a + semicolon to delimit commands. + + If a command is terminated by the control operator &&, the shell exe- + cutes the command in the _b_a_c_k_g_r_o_u_n_d in a subshell. The shell does not + wait for the command to finish, and the return status is 0. Commands + separated by a ;; are executed sequentially; the shell waits for each + command to terminate in turn. The return status is the exit status of + the last command executed. + + The control operators &&&& and |||| denote AND lists and OR lists, respec- + tively.

Variable assignments and builtin com- + mands that affect the shell's environment do not remain in + effect after the command completes. The return status is the + exit status of _l_i_s_t. + + { _l_i_s_t; } + _l_i_s_t is simply executed in the current shell environment. _l_i_s_t + must be terminated with a newline or semicolon. This is known + as a _g_r_o_u_p _c_o_m_m_a_n_d. The return status is the exit status of + _l_i_s_t. Note that unlike the metacharacters (( and )), {{ and }} are + _r_e_s_e_r_v_e_d _w_o_r_d_s and must occur where a reserved word is permitted + to be recognized.

Condi- + tional operators such as --ff must be unquoted to be recognized as + primaries. + + When the ==== and !!== operators are used, the string to the right + of the operator is considered a pattern and matched according to + the rules described below under PPaatttteerrnn MMaattcchhiinngg. If the shell + option nnooccaasseemmaattcchh is enabled, the match is performed without + regard to the case of alphabetic characters. The return value + is 0 if the string matches (====) or does not match (!!==) the pat- + tern, and 1 otherwise. Any part of the pattern may be quoted to + force it to be matched as a string. + + An additional binary operator, ==~~, is available, with the same + precedence as ==== and !!==. When it is used, the string to the + right of the operator is considered an extended regular expres- + sion and matched accordingly (as in _r_e_g_e_x(3)). The return value + is 0 if the string matches the pattern, and 1 otherwise. If the + regular expression is syntactically incorrect, the conditional + expression's return value is 2. If the shell option nnooccaasseemmaattcchh + is enabled, the match is performed without regard to the case of + alphabetic characters.

Quoting can be used to disable special treatment + for special characters, to prevent reserved words from being recognized + as such, and to prevent parameter expansion. + + Each of the _m_e_t_a_c_h_a_r_a_c_t_e_r_s listed above under DDEEFFIINNIITTIIOONNSS has special + meaning to the shell and must be quoted if it is to represent itself. + + When the command history expansion facilities are being used (see HHIISS-- + TTOORRYY EEXXPPAANNSSIIOONN below), the _h_i_s_t_o_r_y _e_x_p_a_n_s_i_o_n character, usually !!, must + be quoted to prevent history expansion. + + There are three quoting mechanisms: the _e_s_c_a_p_e _c_h_a_r_a_c_t_e_r, single + quotes, and double quotes. + + A non-quoted backslash (\\) is the _e_s_c_a_p_e _c_h_a_r_a_c_t_e_r. It preserves the + literal value of the next character that follows, with the exception of + . If a \\ pair appears, and the backslash is not + itself quoted, the \\ is treated as a line continuation (that + is, it is removed from the input stream and effectively ignored). + + Enclosing characters in single quotes preserves the literal value of + each character within the quotes. A single quote may not occur between + single quotes, even when preceded by a backslash. + + Enclosing characters in double quotes preserves the literal value of + all characters within the quotes, with the exception of $$, ``, \\, and, + when history expansion is enabled, !!. The characters $$ and `` retain + their special meaning within double quotes. The backslash retains its + special meaning only when followed by one of the following characters: + $$, ``, "", \\, or <>. A double quote may be quoted within double + quotes by preceding it with a backslash. If enabled, history expansion + will be performed unless an !! appearing in double quotes is escaped + using a backslash.

If the string + is translated and replaced, the replacement is double-quoted. + +PPAARRAAMMEETTEERRSS + A _p_a_r_a_m_e_t_e_r is an entity that stores values. It can be a _n_a_m_e, a num- + ber, or one of the special characters listed below under SSppeecciiaall PPaarraamm-- + eetteerrss. A _v_a_r_i_a_b_l_e is a parameter denoted by a _n_a_m_e. A variable has a + _v_a_l_u_e and zero or more _a_t_t_r_i_b_u_t_e_s. Attributes are assigned using the + ddeeccllaarree builtin command (see ddeeccllaarree below in SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS). + + A parameter is set if it has been assigned a value. The null string is + a valid value. Once a variable is set, it may be unset only by using + the uunnsseett builtin command (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below). + + A _v_a_r_i_a_b_l_e may be assigned to by a statement of the form + + _n_a_m_e=[_v_a_l_u_e] + + If _v_a_l_u_e is not given, the variable is assigned the null string. All + _v_a_l_u_e_s undergo tilde expansion, parameter and variable expansion, com- + mand substitution, arithmetic expansion, and quote removal (see EEXXPPAANN-- + SSIIOONN below). If the variable has its iinntteeggeerr attribute set, then _v_a_l_u_e + is evaluated as an arithmetic expression even if the $((...)) expansion + is not used (see AArriitthhmmeettiicc EExxppaannssiioonn below). Word splitting is not + performed, with the exception of ""$$@@"" as explained below under SSppeecciiaall + PPaarraammeetteerrss. Pathname expansion is not performed. Assignment state- + ments may also appear as arguments to the aalliiaass, ddeeccllaarree, ttyyppeesseett, + eexxppoorrtt, rreeaaddoonnllyy, and llooccaall builtin commands. + + In the context where an assignment statement is assigning a value to a + shell variable or array index, the += operator can be used to append to + or add to the variable's previous value. When += is applied to a vari- + able for which the integer attribute has been set, _v_a_l_u_e is evaluated + as an arithmetic expression and added to the variable's current value, + which is also evaluated. When += is applied to an array variable using + compound assignment (see AArrrraayyss below), the variable's value is not + unset (as it is when using =), and new values are appended to the array + beginning at one greater than the array's maximum index. When applied + to a string-valued variable, _v_a_l_u_e is expanded and appended to the + variable's value. + + PPoossiittiioonnaall PPaarraammeetteerrss + A _p_o_s_i_t_i_o_n_a_l _p_a_r_a_m_e_t_e_r is a parameter denoted by one or more digits, + other than the single digit 0. Positional parameters are assigned from + the shell's arguments when it is invoked, and may be reassigned using + the sseett builtin command. Positional parameters may not be assigned to + with assignment statements. The positional parameters are temporarily + replaced when a shell function is executed (see FFUUNNCCTTIIOONNSS below). + + When a positional parameter consisting of more than a single digit is + expanded, it must be enclosed in braces (see EEXXPPAANNSSIIOONN below). + + SSppeecciiaall PPaarraammeetteerrss + The shell treats several parameters specially. These parameters may + only be referenced; assignment to them is not allowed. + ** Expands to the positional parameters, starting from one. When + the expansion occurs within double quotes, it expands to a sin- + gle word with the value of each parameter separated by the first + character of the IIFFSS special variable. That is, "$$**" is equiva- + lent to "$$11_c$$22_c......", where _c is the first character of the value + of the IIFFSS variable. If IIFFSS is unset, the parameters are sepa- + rated by spaces. If IIFFSS is null, the parameters are joined + without intervening separators. + @@ Expands to the positional parameters, starting from one. When + the expansion occurs within double quotes, each parameter + expands to a separate word. That is, "$$@@" is equivalent to "$$11" + "$$22" ... If the double-quoted expansion occurs within a word, + the expansion of the first parameter is joined with the begin- + ning part of the original word, and the expansion of the last + parameter is joined with the last part of the original word. + When there are no positional parameters, "$$@@" and $$@@ expand to + nothing (i.e., they are removed). + ## Expands to the number of positional parameters in decimal. + ?? Expands to the status of the most recently executed foreground + pipeline. + -- Expands to the current option flags as specified upon invoca- + tion, by the sseett builtin command, or those set by the shell + itself (such as the --ii option). + $$ Expands to the process ID of the shell.

The value of BBAASSHH__EENNVV is + subjected to parameter expansion, command substitution, and + arithmetic expansion before being interpreted as a file name. + PPAATTHH is not used to search for the resultant file name. + CCDDPPAATTHH The search path for the ccdd command. This is a colon-separated + list of directories in which the shell looks for destination + directories specified by the ccdd command. A sample value is + ".:~:/usr". + CCOOLLUUMMNNSS + Used by the sseelleecctt builtin command to determine the terminal + width when printing selection lists. Automatically set upon + receipt of a SIGWINCH. + CCOOMMPPRREEPPLLYY + An array variable from which bbaasshh reads the possible completions + generated by a shell function invoked by the programmable com- + pletion facility (see PPrrooggrraammmmaabbllee CCoommpplleettiioonn below). + EEMMAACCSS If bbaasshh finds this variable in the environment when the shell + starts with value "t", it assumes that the shell is running in + an emacs shell buffer and disables line editing. + FFCCEEDDIITT The default editor for the ffcc builtin command. + FFIIGGNNOORREE + A colon-separated list of suffixes to ignore when performing + filename completion (see RREEAADDLLIINNEE below). A filename whose suf- + fix matches one of the entries in FFIIGGNNOORREE is excluded from the + list of matched filenames. A sample value is ".o:~". + GGLLOOBBIIGGNNOORREE + A colon-separated list of patterns defining the set of filenames + to be ignored by pathname expansion. If a filename matched by a + pathname expansion pattern also matches one of the patterns in + GGLLOOBBIIGGNNOORREE, it is removed from the list of matches. + HHIISSTTCCOONNTTRROOLL + A colon-separated list of values controlling how commands are + saved on the history list. If the list of values includes + _i_g_n_o_r_e_s_p_a_c_e, lines which begin with a ssppaaccee character are not + saved in the history list. A value of _i_g_n_o_r_e_d_u_p_s causes lines + matching the previous history entry to not be saved. A value of + _i_g_n_o_r_e_b_o_t_h is shorthand for _i_g_n_o_r_e_s_p_a_c_e and _i_g_n_o_r_e_d_u_p_s. A value + of _e_r_a_s_e_d_u_p_s causes all previous lines matching the current line + to be removed from the history list before that line is saved. + Any value not in the above list is ignored. If HHIISSTTCCOONNTTRROOLL is + unset, or does not include a valid value, all lines read by the + shell parser are saved on the history list, subject to the value + of HHIISSTTIIGGNNOORREE. The second and subsequent lines of a multi-line + compound command are not tested, and are added to the history + regardless of the value of HHIISSTTCCOONNTTRROOLL. + HHIISSTTFFIILLEE + The name of the file in which command history is saved (see HHIISS-- + TTOORRYY below). The default value is _~_/_._b_a_s_h___h_i_s_t_o_r_y. If unset, + the command history is not saved when an interactive shell + exits. + HHIISSTTFFIILLEESSIIZZEE + The maximum number of lines contained in the history file. When + this variable is assigned a value, the history file is trun- + cated, if necessary, to contain no more than that number of + lines. The default value is 500. The history file is also + truncated to this size after writing it when an interactive + shell exits. + HHIISSTTIIGGNNOORREE + A colon-separated list of patterns used to decide which command + lines should be saved on the history list. Each pattern is + anchored at the beginning of the line and must match the com- + plete line (no implicit `**' is appended). Each pattern is + tested against the line after the checks specified by HHIISSTTCCOONN-- + TTRROOLL are applied. In addition to the normal shell pattern + matching characters, `&&' matches the previous history line. `&&' + may be escaped using a backslash; the backslash is removed + before attempting a match. The second and subsequent lines of a + multi-line compound command are not tested, and are added to the + history regardless of the value of HHIISSTTIIGGNNOORREE. + HHIISSTTSSIIZZEE + The number of commands to remember in the command history (see + HHIISSTTOORRYY below). The default value is 500. + HHIISSTTTTIIMMEEFFOORRMMAATT + If this variable is set and not null, its value is used as a + format string for _s_t_r_f_t_i_m_e(3) to print the time stamp associated + with each history entry displayed by the hhiissttoorryy builtin. If + this variable is set, time stamps are written to the history + file so they may be preserved across shell sessions. + HHOOMMEE The home directory of the current user; the default argument for + the ccdd builtin command. The value of this variable is also used + when performing tilde expansion. + HHOOSSTTFFIILLEE + Contains the name of a file in the same format as _/_e_t_c_/_h_o_s_t_s + that should be read when the shell needs to complete a hostname. + The list of possible hostname completions may be changed while + the shell is running; the next time hostname completion is + attempted after the value is changed, bbaasshh adds the contents of + the new file to the existing list. If HHOOSSTTFFIILLEE is set, but has + no value, bbaasshh attempts to read _/_e_t_c_/_h_o_s_t_s to obtain the list of + possible hostname completions. When HHOOSSTTFFIILLEE is unset, the + hostname list is cleared. + IIFFSS The _I_n_t_e_r_n_a_l _F_i_e_l_d _S_e_p_a_r_a_t_o_r that is used for word splitting + after expansion and to split lines into words with the rreeaadd + builtin command. The default value is ``''. + IIGGNNOORREEEEOOFF + Controls the action of an interactive shell on receipt of an EEOOFF + character as the sole input. If set, the value is the number of + consecutive EEOOFF characters which must be typed as the first + characters on an input line before bbaasshh exits. If the variable + exists but does not have a numeric value, or has no value, the + default value is 10. If it does not exist, EEOOFF signifies the + end of input to the shell. + IINNPPUUTTRRCC + The filename for the rreeaaddlliinnee startup file, overriding the + default of _~_/_._i_n_p_u_t_r_c (see RREEAADDLLIINNEE below). + LLAANNGG Used to determine the locale category for any category not + specifically selected with a variable starting with LLCC__. + LLCC__AALLLL This variable overrides the value of LLAANNGG and any other LLCC__ + variable specifying a locale category. + LLCC__CCOOLLLLAATTEE + This variable determines the collation order used when sorting + the results of pathname expansion, and determines the behavior + of range expressions, equivalence classes, and collating + sequences within pathname expansion and pattern matching. + LLCC__CCTTYYPPEE + This variable determines the interpretation of characters and + the behavior of character classes within pathname expansion and + pattern matching. + LLCC__MMEESSSSAAGGEESS + This variable determines the locale used to translate double- + quoted strings preceded by a $$. + LLCC__NNUUMMEERRIICC + This variable determines the locale category used for number + formatting. + LLIINNEESS Used by the sseelleecctt builtin command to determine the column + length for printing selection lists. Automatically set upon + receipt of a SIGWINCH. + MMAAIILL If this parameter is set to a file name and the MMAAIILLPPAATTHH vari- + able is not set, bbaasshh informs the user of the arrival of mail in + the specified file. + MMAAIILLCCHHEECCKK + Specifies how often (in seconds) bbaasshh checks for mail. The + default is 60 seconds. When it is time to check for mail, the + shell does so before displaying the primary prompt. If this + variable is unset, or set to a value that is not a number + greater than or equal to zero, the shell disables mail checking. + MMAAIILLPPAATTHH + A colon-separated list of file names to be checked for mail. + The message to be printed when mail arrives in a particular file + may be specified by separating the file name from the message + with a `?'. When used in the text of the message, $$__ expands to + the name of the current mailfile. Example: + MMAAIILLPPAATTHH='/var/mail/bfox?"You have mail":~/shell-mail?"$_ has + mail!"' + BBaasshh supplies a default value for this variable, but the loca- + tion of the user mail files that it uses is system dependent + (e.g., /var/mail/$$UUSSEERR). + OOPPTTEERRRR If set to the value 1, bbaasshh displays error messages generated by + the ggeettooppttss builtin command (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below). + OOPPTTEERRRR is initialized to 1 each time the shell is invoked or a + shell script is executed. + PPAATTHH The search path for commands. It is a colon-separated list of + directories in which the shell looks for commands (see CCOOMMMMAANNDD + EEXXEECCUUTTIIOONN below). A zero-length (null) directory name in the + value of PPAATTHH indicates the current directory. A null directory + name may appear as two adjacent colons, or as an initial or + trailing colon. The default path is system-dependent, and is + set by the administrator who installs bbaasshh. A common value is + ``/usr/gnu/bin:/usr/local/bin:/usr/ucb:/bin:/usr/bin''. + PPOOSSIIXXLLYY__CCOORRRREECCTT + If this variable is in the environment when bbaasshh starts, the + shell enters _p_o_s_i_x _m_o_d_e before reading the startup files, as if + the ----ppoossiixx invocation option had been supplied. If it is set + while the shell is running, bbaasshh enables _p_o_s_i_x _m_o_d_e, as if the + command _s_e_t _-_o _p_o_s_i_x had been executed. + PPRROOMMPPTT__CCOOMMMMAANNDD + If set, the value is executed as a command prior to issuing each + primary prompt. + PPSS11 The value of this parameter is expanded (see PPRROOMMPPTTIINNGG below) + and used as the primary prompt string. The default value is + ``\\ss--\\vv\\$$ ''. + PPSS22 The value of this parameter is expanded as with PPSS11 and used as + the secondary prompt string. The default is ``>> ''. + PPSS33 The value of this parameter is used as the prompt for the sseelleecctt + command (see SSHHEELLLL GGRRAAMMMMAARR above). + PPSS44 The value of this parameter is expanded as with PPSS11 and the + value is printed before each command bbaasshh displays during an + execution trace. The first character of PPSS44 is replicated mul- + tiple times, as necessary, to indicate multiple levels of indi- + rection. The default is ``++ ''. + SSHHEELLLL The full pathname to the shell is kept in this environment vari- + able. If it is not set when the shell starts, bbaasshh assigns to + it the full pathname of the current user's login shell. + TTIIMMEEFFOORRMMAATT + The value of this parameter is used as a format string specify- + ing how the timing information for pipelines prefixed with the + ttiimmee reserved word should be displayed. The %% character intro- + duces an escape sequence that is expanded to a time value or + other information. The escape sequences and their meanings are + as follows; the braces denote optional portions. + %%%% A literal %%. + %%[[_p]][[ll]]RR The elapsed time in seconds. + %%[[_p]][[ll]]UU The number of CPU seconds spent in user mode. + %%[[_p]][[ll]]SS The number of CPU seconds spent in system mode. + %%PP The CPU percentage, computed as (%U + %S) / %R. + + The optional _p is a digit specifying the _p_r_e_c_i_s_i_o_n, the number + of fractional digits after a decimal point. A value of 0 causes + no decimal point or fraction to be output. At most three places + after the decimal point may be specified; values of _p greater + than 3 are changed to 3. If _p is not specified, the value 3 is + used. + + The optional ll specifies a longer format, including minutes, of + the form _M_Mm_S_S._F_Fs. The value of _p determines whether or not + the fraction is included. + + If this variable is not set, bbaasshh acts as if it had the value + $$''\\nnrreeaall\\tt%%33llRR\\nnuusseerr\\tt%%33llUU\\nnssyyss%%33llSS''. If the value is null, no + timing information is displayed. A trailing newline is added + when the format string is displayed. + + TTMMOOUUTT If set to a value greater than zero, TTMMOOUUTT is treated as the + default timeout for the rreeaadd builtin. The sseelleecctt command termi- + nates if input does not arrive after TTMMOOUUTT seconds when input is + coming from a terminal. In an interactive shell, the value is + interpreted as the number of seconds to wait for input after + issuing the primary prompt. BBaasshh terminates after waiting for + that number of seconds if input does not arrive. + + TTMMPPDDIIRR If set, BBaasshh uses its value as the name of a directory in which + BBaasshh creates temporary files for the shell's use. + + aauuttoo__rreessuummee + This variable controls how the shell interacts with the user and + job control. If this variable is set, single word simple com- + mands without redirections are treated as candidates for resump- + tion of an existing stopped job. There is no ambiguity allowed; + if there is more than one job beginning with the string typed, + the job most recently accessed is selected. The _n_a_m_e of a + stopped job, in this context, is the command line used to start + it. If set to the value _e_x_a_c_t, the string supplied must match + the name of a stopped job exactly; if set to _s_u_b_s_t_r_i_n_g, the + string supplied needs to match a substring of the name of a + stopped job. The _s_u_b_s_t_r_i_n_g value provides functionality analo- + gous to the %%?? job identifier (see JJOOBB CCOONNTTRROOLL below). If set + to any other value, the supplied string must be a prefix of a + stopped job's name; this provides functionality analogous to the + %%_s_t_r_i_n_g job identifier. + + hhiissttcchhaarrss + The two or three characters which control history expansion and + tokenization (see HHIISSTTOORRYY EEXXPPAANNSSIIOONN below). The first character + is the _h_i_s_t_o_r_y _e_x_p_a_n_s_i_o_n character, the character which signals + the start of a history expansion, normally `!!'. The second + character is the _q_u_i_c_k _s_u_b_s_t_i_t_u_t_i_o_n character, which is used as + shorthand for re-running the previous command entered, substi- + tuting one string for another in the command. The default is + `^^'. The optional third character is the character which indi- + cates that the remainder of the line is a comment when found as + the first character of a word, normally `##'. The history com- + ment character causes history substitution to be skipped for the + remaining words on the line. It does not necessarily cause the + shell parser to treat the rest of the line as a comment. + + AArrrraayyss + BBaasshh provides one-dimensional array variables. Any variable may be + used as an array; the ddeeccllaarree builtin will explicitly declare an array. + There is no maximum limit on the size of an array, nor any requirement + that members be indexed or assigned contiguously. Arrays are indexed + using integers and are zero-based. + + An array is created automatically if any variable is assigned to using + the syntax _n_a_m_e[_s_u_b_s_c_r_i_p_t]=_v_a_l_u_e. The _s_u_b_s_c_r_i_p_t is treated as an + arithmetic expression that must evaluate to a number greater than or + equal to zero. To explicitly declare an array, use ddeeccllaarree --aa _n_a_m_e + (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below). ddeeccllaarree --aa _n_a_m_e[[_s_u_b_s_c_r_i_p_t]] is also + accepted; the _s_u_b_s_c_r_i_p_t is ignored. Attributes may be specified for an + array variable using the ddeeccllaarree and rreeaaddoonnllyy builtins. Each attribute + applies to all members of an array. + + Arrays are assigned to using compound assignments of the form + _n_a_m_e=((value_1 ... value_n)), where each _v_a_l_u_e is of the form [_s_u_b_- + _s_c_r_i_p_t]=_s_t_r_i_n_g. Only _s_t_r_i_n_g is required. If the optional brackets and + subscript are supplied, that index is assigned to; otherwise the index + of the element assigned is the last index assigned to by the statement + plus one. Indexing starts at zero. This syntax is also accepted by + the ddeeccllaarree builtin. Individual array elements may be assigned to + using the _n_a_m_e[_s_u_b_s_c_r_i_p_t]=_v_a_l_u_e syntax introduced above. + + Any element of an array may be referenced using ${_n_a_m_e[_s_u_b_s_c_r_i_p_t]}. + The braces are required to avoid conflicts with pathname expansion. If + _s_u_b_s_c_r_i_p_t is @@ or **, the word expands to all members of _n_a_m_e. These + subscripts differ only when the word appears within double quotes. If + the word is double-quoted, ${_n_a_m_e[*]} expands to a single word with the + value of each array member separated by the first character of the IIFFSS + special variable, and ${_n_a_m_e[@]} expands each element of _n_a_m_e to a sep- + arate word. When there are no array members, ${_n_a_m_e[@]} expands to + nothing. If the double-quoted expansion occurs within a word, the + expansion of the first parameter is joined with the beginning part of + the original word, and the expansion of the last parameter is joined + with the last part of the original word. This is analogous to the + expansion of the special parameters ** and @@ (see SSppeecciiaall PPaarraammeetteerrss + above). ${#_n_a_m_e[_s_u_b_s_c_r_i_p_t]} expands to the length of ${_n_a_m_e[_s_u_b_- + _s_c_r_i_p_t]}. If _s_u_b_s_c_r_i_p_t is ** or @@, the expansion is the number of ele- + ments in the array. Referencing an array variable without a subscript + is equivalent to referencing element zero. + + The uunnsseett builtin is used to destroy arrays. uunnsseett _n_a_m_e[_s_u_b_s_c_r_i_p_t] + destroys the array element at index _s_u_b_s_c_r_i_p_t. Care must be taken to + avoid unwanted side effects caused by filename generation. uunnsseett _n_a_m_e, + where _n_a_m_e is an array, or uunnsseett _n_a_m_e[_s_u_b_s_c_r_i_p_t], where _s_u_b_s_c_r_i_p_t is ** + or @@, removes the entire array. + + The ddeeccllaarree, llooccaall, and rreeaaddoonnllyy builtins each accept a --aa option to + specify an array. The rreeaadd builtin accepts a --aa option to assign a + list of words read from the standard input to an array. The sseett and + ddeeccllaarree builtins display array values in a way that allows them to be + reused as assignments. + +EEXXPPAANNSSIIOONN + Expansion is performed on the command line after it has been split into + words. There are seven kinds of expansion performed: _b_r_a_c_e _e_x_p_a_n_s_i_o_n, + _t_i_l_d_e _e_x_p_a_n_s_i_o_n, _p_a_r_a_m_e_t_e_r _a_n_d _v_a_r_i_a_b_l_e _e_x_p_a_n_s_i_o_n, _c_o_m_m_a_n_d _s_u_b_s_t_i_t_u_- + _t_i_o_n, _a_r_i_t_h_m_e_t_i_c _e_x_p_a_n_s_i_o_n, _w_o_r_d _s_p_l_i_t_t_i_n_g, and _p_a_t_h_n_a_m_e _e_x_p_a_n_s_i_o_n. + + The order of expansions is: brace expansion, tilde expansion, parame- + ter, variable and arithmetic expansion and command substitution (done + in a left-to-right fashion), word splitting, and pathname expansion. + + On systems that can support it, there is an additional expansion avail- + able: _p_r_o_c_e_s_s _s_u_b_s_t_i_t_u_t_i_o_n. + + Only brace expansion, word splitting, and pathname expansion can change + the number of words of the expansion; other expansions expand a single + word to a single word. The only exceptions to this are the expansions + of "$$@@" and "$${{_n_a_m_e[[@@]]}}" as explained above (see PPAARRAAMMEETTEERRSS). + + BBrraaccee EExxppaannssiioonn + _B_r_a_c_e _e_x_p_a_n_s_i_o_n is a mechanism by which arbitrary strings may be gener- + ated. This mechanism is similar to _p_a_t_h_n_a_m_e _e_x_p_a_n_s_i_o_n, but the file- + names generated need not exist. Patterns to be brace expanded take the + form of an optional _p_r_e_a_m_b_l_e, followed by either a series of comma-sep- + arated strings or a sequence expression between a pair of braces, fol- + lowed by an optional _p_o_s_t_s_c_r_i_p_t. The preamble is prefixed to each + string contained within the braces, and the postscript is then appended + to each resulting string, expanding left to right. + + Brace expansions may be nested. The results of each expanded string + are not sorted; left to right order is preserved. For example, + a{{d,c,b}}e expands into `ade ace abe'. + + A sequence expression takes the form {{_x...._y}}, where _x and _y are either + integers or single characters. When integers are supplied, the expres- + sion expands to each number between _x and _y, inclusive. When charac- + ters are supplied, the expression expands to each character lexico- + graphically between _x and _y, inclusive. Note that both _x and _y must be + of the same type. + + Brace expansion is performed before any other expansions, and any char- + acters special to other expansions are preserved in the result. It is + strictly textual. BBaasshh does not apply any syntactic interpretation to + the context of the expansion or the text between the braces. + + A correctly-formed brace expansion must contain unquoted opening and + closing braces, and at least one unquoted comma or a valid sequence + expression. Any incorrectly formed brace expansion is left unchanged. + A {{ or ,, may be quoted with a backslash to prevent its being considered + part of a brace expression. To avoid conflicts with parameter expan- + sion, the string $${{ is not considered eligible for brace expansion. + + This construct is typically used as shorthand when the common prefix of + the strings to be generated is longer than in the above example: + + mkdir /usr/local/src/bash/{old,new,dist,bugs} + or + chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}} + + Brace expansion introduces a slight incompatibility with historical + versions of sshh. sshh does not treat opening or closing braces specially + when they appear as part of a word, and preserves them in the output. + BBaasshh removes braces from words as a consequence of brace expansion. + For example, a word entered to sshh as _f_i_l_e_{_1_,_2_} appears identically in + the output. The same word is output as _f_i_l_e_1 _f_i_l_e_2 after expansion by + bbaasshh. If strict compatibility with sshh is desired, start bbaasshh with the + ++BB option or disable brace expansion with the ++BB option to the sseett com- + mand (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below). + + TTiillddee EExxppaannssiioonn + If a word begins with an unquoted tilde character (`~~'), all of the + characters preceding the first unquoted slash (or all characters, if + there is no unquoted slash) are considered a _t_i_l_d_e_-_p_r_e_f_i_x. If none of + the characters in the tilde-prefix are quoted, the characters in the + tilde-prefix following the tilde are treated as a possible _l_o_g_i_n _n_a_m_e. + If this login name is the null string, the tilde is replaced with the + value of the shell parameter HHOOMMEE. If HHOOMMEE is unset, the home direc- + tory of the user executing the shell is substituted instead. Other- + wise, the tilde-prefix is replaced with the home directory associated + with the specified login name. + + If the tilde-prefix is a `~+', the value of the shell variable PPWWDD + replaces the tilde-prefix. If the tilde-prefix is a `~-', the value of + the shell variable OOLLDDPPWWDD, if it is set, is substituted. If the char- + acters following the tilde in the tilde-prefix consist of a number _N, + optionally prefixed by a `+' or a `-', the tilde-prefix is replaced + with the corresponding element from the directory stack, as it would be + displayed by the ddiirrss builtin invoked with the tilde-prefix as an argu- + ment. If the characters following the tilde in the tilde-prefix con- + sist of a number without a leading `+' or `-', `+' is assumed. + + If the login name is invalid, or the tilde expansion fails, the word is + unchanged. + + Each variable assignment is checked for unquoted tilde-prefixes immedi- + ately following a :: or the first ==. In these cases, tilde expansion is + also performed. Consequently, one may use file names with tildes in + assignments to PPAATTHH, MMAAIILLPPAATTHH, and CCDDPPAATTHH, and the shell assigns the + expanded value. + + PPaarraammeetteerr EExxppaannssiioonn + The `$$' character introduces parameter expansion, command substitution, + or arithmetic expansion. The parameter name or symbol to be expanded + may be enclosed in braces, which are optional but serve to protect the + variable to be expanded from characters immediately following it which + could be interpreted as part of the name. + + When braces are used, the matching ending brace is the first `}}' not + escaped by a backslash or within a quoted string, and not within an + embedded arithmetic expansion, command substitution, or parameter + expansion. + + ${_p_a_r_a_m_e_t_e_r} + The value of _p_a_r_a_m_e_t_e_r is substituted. The braces are required + when _p_a_r_a_m_e_t_e_r is a positional parameter with more than one + digit, or when _p_a_r_a_m_e_t_e_r is followed by a character which is not + to be interpreted as part of its name. + + If the first character of _p_a_r_a_m_e_t_e_r is an exclamation point, a level of + variable indirection is introduced. BBaasshh uses the value of the vari- + able formed from the rest of _p_a_r_a_m_e_t_e_r as the name of the variable; + this variable is then expanded and that value is used in the rest of + the substitution, rather than the value of _p_a_r_a_m_e_t_e_r itself. This is + known as _i_n_d_i_r_e_c_t _e_x_p_a_n_s_i_o_n. The exceptions to this are the expansions + of ${!_p_r_e_f_i_x*} and ${!!_n_a_m_e[_@]} described below. The exclamation point + must immediately follow the left brace in order to introduce indirec- + tion. + + In each of the cases below, _w_o_r_d is subject to tilde expansion, parame- + ter expansion, command substitution, and arithmetic expansion. When + not performing substring expansion, bbaasshh tests for a parameter that is + unset or null; omitting the colon results in a test only for a parame- + ter that is unset. + + ${_p_a_r_a_m_e_t_e_r::--_w_o_r_d} + UUssee DDeeffaauulltt VVaalluueess.

If IIFFSS + has a value other than the default, then sequences of the whitespace + characters ssppaaccee and ttaabb are ignored at the beginning and end of the + word, as long as the whitespace character is in the value of IIFFSS (an + IIFFSS whitespace character). Any character in IIFFSS that is not IIFFSS white- + space, along with any adjacent IIFFSS whitespace characters, delimits a + field. A sequence of IIFFSS whitespace characters is also treated as a + delimiter. If the value of IIFFSS is null, no word splitting occurs. + + Explicit null arguments ("""" or '''') are retained.

The + first word of the replacement text is tested for aliases, but a word + that is identical to an alias being expanded is not expanded a second + time. This means that one may alias llss to llss --FF, for instance, and + bbaasshh does not try to recursively expand the replacement text. If the + last character of the alias value is a _b_l_a_n_k, then the next command + word following the alias is also checked for alias expansion. + + Aliases are created and listed with the aalliiaass command, and removed with + the uunnaalliiaass command. + + There is no mechanism for using arguments in the replacement text. If + arguments are needed, a shell function should be used (see FFUUNNCCTTIIOONNSS + below). + + Aliases are not expanded when the shell is not interactive, unless the + eexxppaanndd__aalliiaasseess shell option is set using sshhoopptt (see the description of + sshhoopptt under SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below). + + The rules concerning the definition and use of aliases are somewhat + confusing. BBaasshh always reads at least one complete line of input + before executing any of the commands on that line. Aliases are + expanded when a command is read, not when it is executed. Therefore, + an alias definition appearing on the same line as another command does + not take effect until the next line of input is read. The commands + following the alias definition on that line are not affected by the new + alias. This behavior is also an issue when functions are executed. + Aliases are expanded when a function definition is read, not when the + function is executed, because a function definition is itself a com- + pound command. As a consequence, aliases defined in a function are not + available until after that function is executed. To be safe, always + put alias definitions on a separate line, and do not use aalliiaass in com- + pound commands. + + For almost every purpose, aliases are superseded by shell functions. + +FFUUNNCCTTIIOONNSS + A shell function, defined as described above under SSHHEELLLL GGRRAAMMMMAARR, + stores a series of commands for later execution. When the name of a + shell function is used as a simple command name, the list of commands + associated with that function name is executed. Functions are executed + in the context of the current shell; no new process is created to + interpret them (contrast this with the execution of a shell script). + When a function is executed, the arguments to the function become the + positional parameters during its execution. The special parameter ## is + updated to reflect the change. Special parameter 0 is unchanged. The + first element of the FFUUNNCCNNAAMMEE variable is set to the name of the func- + tion while the function is executing. All other aspects of the shell + execution environment are identical between a function and its caller + with the exception that the DDEEBBUUGG and RREETTUURRNN traps (see the description + of the ttrraapp builtin under SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below) are not inher- + ited unless the function has been given the ttrraaccee attribute (see the + description of the ddeeccllaarree builtin below) or the --oo ffuunnccttrraaccee shell + option has been enabled with the sseett builtin (in which case all func- + tions inherit the DDEEBBUUGG and RREETTUURRNN traps). + + Variables local to the function may be declared with the llooccaall builtin + command. Ordinarily, variables and their values are shared between the + function and its caller. + + If the builtin command rreettuurrnn is executed in a function, the function + completes and execution resumes with the next command after the func- + tion call. Any command associated with the RREETTUURRNN trap is executed + before execution resumes. When a function completes, the values of the + positional parameters and the special parameter ## are restored to the + values they had prior to the function's execution. + + Function names and definitions may be listed with the --ff option to the + ddeeccllaarree or ttyyppeesseett builtin commands. The --FF option to ddeeccllaarree or ttyyppee-- + sseett will list the function names only (and optionally the source file + and line number, if the eexxttddeebbuugg shell option is enabled). Functions + may be exported so that subshells automatically have them defined with + the --ff option to the eexxppoorrtt builtin. A function definition may be + deleted using the --ff option to the uunnsseett builtin. Note that shell + functions and variables with the same name may result in multiple iden- + tically-named entries in the environment passed to the shell's chil- + dren. Care should be taken in cases where this may cause a problem. + + Functions may be recursive. No limit is imposed on the number of + recursive calls. + +AARRIITTHHMMEETTIICC EEVVAALLUUAATTIIOONN + The shell allows arithmetic expressions to be evaluated, under certain + circumstances (see the lleett and ddeeccllaarree builtin commands and AArriitthhmmeettiicc + EExxppaannssiioonn). Evaluation is done in fixed-width integers with no check + for overflow, though division by 0 is trapped and flagged as an error. + The operators and their precedence, associativity, and values are the + same as in the C language.

Within an expression, shell + variables may also be referenced by name without using the parameter + expansion syntax. A shell variable that is null or unset evaluates to + 0 when referenced by name without using the parameter expansion syntax. + The value of a variable is evaluated as an arithmetic expression when + it is referenced, or when a variable which has been given the _i_n_t_e_g_e_r + attribute using ddeeccllaarree --ii is assigned a value. A null value evaluates + to 0. A shell variable need not have its integer attribute turned on + to be used in an expression. + + Constants with a leading 0 are interpreted as octal numbers. A leading + 0x or 0X denotes hexadecimal. Otherwise, numbers take the form + [_b_a_s_e_#]n, where _b_a_s_e is a decimal number between 2 and 64 representing + the arithmetic base, and _n is a number in that base. If _b_a_s_e_# is omit- + ted, then base 10 is used. The digits greater than 9 are represented + by the lowercase letters, the uppercase letters, @, and _, in that + order. If _b_a_s_e is less than or equal to 36, lowercase and uppercase + letters may be used interchangeably to represent numbers between 10 and + 35. + + Operators are evaluated in order of precedence.

The words that the parser has marked as variable assignments + (those preceding the command name) and redirections are saved + for later processing. + + 2. The words that are not variable assignments or redirections are + expanded. If any words remain after expansion, the first word + is taken to be the name of the command and the remaining words + are the arguments. + + 3. Redirections are performed as described above under RREEDDIIRREECCTTIIOONN. + + 4. The text after the == in each variable assignment undergoes tilde + expansion, parameter expansion, command substitution, arithmetic + expansion, and quote removal before being assigned to the vari- + able. + + If no command name results, the variable assignments affect the current + shell environment. Otherwise, the variables are added to the environ- + ment of the executed command and do not affect the current shell envi- + ronment. If any of the assignments attempts to assign a value to a + readonly variable, an error occurs, and the command exits with a non- + zero status. + + If no command name results, redirections are performed, but do not + affect the current shell environment. A redirection error causes the + command to exit with a non-zero status. + + If there is a command name left after expansion, execution proceeds as + described below. Otherwise, the command exits. If one of the expan- + sions contained a command substitution, the exit status of the command + is the exit status of the last command substitution performed. If + there were no command substitutions, the command exits with a status of + zero. + +CCOOMMMMAANNDD EEXXEECCUUTTIIOONN + After a command has been split into words, if it results in a simple + command and an optional list of arguments, the following actions are + taken. + + If the command name contains no slashes, the shell attempts to locate + it. If there exists a shell function by that name, that function is + invoked as described above in FFUUNNCCTTIIOONNSS. If the name does not match a + function, the shell searches for it in the list of shell builtins. If + a match is found, that builtin is invoked. + + If the name is neither a shell function nor a builtin, and contains no + slashes, bbaasshh searches each element of the PPAATTHH for a directory con- + taining an executable file by that name. BBaasshh uses a hash table to + remember the full pathnames of executable files (see hhaasshh under SSHHEELLLL + BBUUIILLTTIINN CCOOMMMMAANNDDSS below). A full search of the directories in PPAATTHH is + performed only if the command is not found in the hash table. If the + search is unsuccessful, the shell prints an error message and returns + an exit status of 127. + + If the search is successful, or if the command name contains one or + more slashes, the shell executes the named program in a separate execu- + tion environment. Argument 0 is set to the name given, and the remain- + ing arguments to the command are set to the arguments given, if any. + + If this execution fails because the file is not in executable format, + and the file is not a directory, it is assumed to be a _s_h_e_l_l _s_c_r_i_p_t, a + file containing shell commands. A subshell is spawned to execute it. + This subshell reinitializes itself, so that the effect is as if a new + shell had been invoked to handle the script, with the exception that + the locations of commands remembered by the parent (see hhaasshh below + under SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS) are retained by the child. + + If the program is a file beginning with ##!!, the remainder of the first + line specifies an interpreter for the program. The shell executes the + specified interpreter on operating systems that do not handle this exe- + cutable format themselves. The arguments to the interpreter consist of + a single optional argument following the interpreter name on the first + line of the program, followed by the name of the program, followed by + the command arguments, if any. + +CCOOMMMMAANNDD EEXXEECCUUTTIIOONN EENNVVIIRROONNMMEENNTT + The shell has an _e_x_e_c_u_t_i_o_n _e_n_v_i_r_o_n_m_e_n_t, which consists of the follow- + ing: + + + +o open files inherited by the shell at invocation, as modified by + redirections supplied to the eexxeecc builtin + + +o the current working directory as set by ccdd, ppuusshhdd, or ppooppdd, or + inherited by the shell at invocation + + +o the file creation mode mask as set by uummaasskk or inherited from + the shell's parent + + +o current traps set by ttrraapp + + +o shell parameters that are set by variable assignment or with sseett + or inherited from the shell's parent in the environment + + +o shell functions defined during execution or inherited from the + shell's parent in the environment + + +o options enabled at invocation (either by default or with com- + mand-line arguments) or by sseett + + +o options enabled by sshhoopptt + + +o shell aliases defined with aalliiaass + + +o various process IDs, including those of background jobs, the + value of $$$$, and the value of $$PPPPIIDD + + When a simple command other than a builtin or shell function is to be + executed, it is invoked in a separate execution environment that con- + sists of the following.

Builtin commands that are invoked as part of a pipeline are also + executed in a subshell environment. Changes made to the subshell envi- + ronment cannot affect the shell's execution environment. + + If a command is followed by a && and job control is not active, the + default standard input for the command is the empty file _/_d_e_v_/_n_u_l_l. + Otherwise, the invoked command inherits the file descriptors of the + calling shell as modified by redirections. + +EENNVVIIRROONNMMEENNTT + When a program is invoked it is given an array of strings called the + _e_n_v_i_r_o_n_m_e_n_t. This is a list of _n_a_m_e-_v_a_l_u_e pairs, of the form + _n_a_m_e=_v_a_l_u_e. + + The shell provides several ways to manipulate the environment. On + invocation, the shell scans its own environment and creates a parameter + for each name found, automatically marking it for _e_x_p_o_r_t to child pro- + cesses. Executed commands inherit the environment. The eexxppoorrtt and + ddeeccllaarree --xx commands allow parameters and functions to be added to and + deleted from the environment. If the value of a parameter in the envi- + ronment is modified, the new value becomes part of the environment, + replacing the old. The environment inherited by any executed command + consists of the shell's initial environment, whose values may be modi- + fied in the shell, less any pairs removed by the uunnsseett command, plus + any additions via the eexxppoorrtt and ddeeccllaarree --xx commands. + + The environment for any _s_i_m_p_l_e _c_o_m_m_a_n_d or function may be augmented + temporarily by prefixing it with parameter assignments, as described + above in PPAARRAAMMEETTEERRSS. These assignment statements affect only the envi- + ronment seen by that command. + + If the --kk option is set (see the sseett builtin command below), then _a_l_l + parameter assignments are placed in the environment for a command, not + just those that precede the command name. + + When bbaasshh invokes an external command, the variable __ is set to the + full file name of the command and passed to that command in its envi- + ronment. + +EEXXIITT SSTTAATTUUSS + For the shell's purposes, a command which exits with a zero exit status + has succeeded. An exit status of zero indicates success. A non-zero + exit status indicates failure. When a command terminates on a fatal + signal _N, bbaasshh uses the value of 128+_N as the exit status. + + If a command is not found, the child process created to execute it + returns a status of 127. If a command is found but is not executable, + the return status is 126. + + If a command fails because of an error during expansion or redirection, + the exit status is greater than zero. + + Shell builtin commands return a status of 0 (_t_r_u_e) if successful, and + non-zero (_f_a_l_s_e) if an error occurs while they execute. All builtins + return an exit status of 2 to indicate incorrect usage. + + BBaasshh itself returns the exit status of the last command executed, + unless a syntax error occurs, in which case it exits with a non-zero + value. See also the eexxiitt builtin command below. + +SSIIGGNNAALLSS + When bbaasshh is interactive, in the absence of any traps, it ignores + SSIIGGTTEERRMM (so that kkiillll 00 does not kill an interactive shell), and SSIIGGIINNTT + is caught and handled (so that the wwaaiitt builtin is interruptible). In + all cases, bbaasshh ignores SSIIGGQQUUIITT. If job control is in effect, bbaasshh + ignores SSIIGGTTTTIINN, SSIIGGTTTTOOUU, and SSIIGGTTSSTTPP. + + Non-builtin commands run by bbaasshh have signal handlers set to the values + inherited by the shell from its parent. When job control is not in + effect, asynchronous commands ignore SSIIGGIINNTT and SSIIGGQQUUIITT in addition to + these inherited handlers. Commands run as a result of command substi- + tution ignore the keyboard-generated job control signals SSIIGGTTTTIINN, SSIIGGTT-- + TTOOUU, and SSIIGGTTSSTTPP. + + The shell exits by default upon receipt of a SSIIGGHHUUPP. Before exiting, + an interactive shell resends the SSIIGGHHUUPP to all jobs, running or + stopped. Stopped jobs are sent SSIIGGCCOONNTT to ensure that they receive the + SSIIGGHHUUPP. To prevent the shell from sending the signal to a particular + job, it should be removed from the jobs table with the ddiissoowwnn builtin + (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below) or marked to not receive SSIIGGHHUUPP + using ddiissoowwnn --hh. + + If the hhuuppoonneexxiitt shell option has been set with sshhoopptt, bbaasshh sends a + SSIIGGHHUUPP to all jobs when an interactive login shell exits. + + If bbaasshh is waiting for a command to complete and receives a signal for + which a trap has been set, the trap will not be executed until the com- + mand completes. When bbaasshh is waiting for an asynchronous command via + the wwaaiitt builtin, the reception of a signal for which a trap has been + set will cause the wwaaiitt builtin to return immediately with an exit sta- + tus greater than 128, immediately after which the trap is executed. + +JJOOBB CCOONNTTRROOLL + _J_o_b _c_o_n_t_r_o_l refers to the ability to selectively stop (_s_u_s_p_e_n_d) the + execution of processes and continue (_r_e_s_u_m_e) their execution at a later + point. A user typically employs this facility via an interactive + interface supplied jointly by the system's terminal driver and bbaasshh. + + The shell associates a _j_o_b with each pipeline. It keeps a table of + currently executing jobs, which may be listed with the jjoobbss command. + When bbaasshh starts a job asynchronously (in the _b_a_c_k_g_r_o_u_n_d), it prints a + line that looks like: + + [1] 25647 + + indicating that this job is job number 1 and that the process ID of the + last process in the pipeline associated with this job is 25647. All of + the processes in a single pipeline are members of the same job. BBaasshh + uses the _j_o_b abstraction as the basis for job control. + + To facilitate the implementation of the user interface to job control, + the operating system maintains the notion of a _c_u_r_r_e_n_t _t_e_r_m_i_n_a_l _p_r_o_c_e_s_s + _g_r_o_u_p _I_D. Members of this process group (processes whose process group + ID is equal to the current terminal process group ID) receive keyboard- + generated signals such as SSIIGGIINNTT. These processes are said to be in + the _f_o_r_e_g_r_o_u_n_d. _B_a_c_k_g_r_o_u_n_d processes are those whose process group ID + differs from the terminal's; such processes are immune to keyboard-gen- + erated signals. Only foreground processes are allowed to read from or + write to the terminal. Background processes which attempt to read from + (write to) the terminal are sent a SSIIGGTTTTIINN ((SSIIGGTTTTOOUU)) signal by the ter- + minal driver, which, unless caught, suspends the process. + + If the operating system on which bbaasshh is running supports job control, + bbaasshh contains facilities to use it. Typing the _s_u_s_p_e_n_d character (typ- + ically ^^ZZ, Control-Z) while a process is running causes that process to + be stopped and returns control to bbaasshh. Typing the _d_e_l_a_y_e_d _s_u_s_p_e_n_d + character (typically ^^YY, Control-Y) causes the process to be stopped + when it attempts to read input from the terminal, and control to be + returned to bbaasshh. The user may then manipulate the state of this job, + using the bbgg command to continue it in the background, the ffgg command + to continue it in the foreground, or the kkiillll command to kill it. A ^^ZZ + takes effect immediately, and has the additional side effect of causing + pending output and typeahead to be discarded. + + There are a number of ways to refer to a job in the shell. The charac- + ter %% introduces a job name. Job number _n may be referred to as %%nn. A + job may also be referred to using a prefix of the name used to start + it, or using a substring that appears in its command line. For exam- + ple, %%ccee refers to a stopped ccee job. If a prefix matches more than one + job, bbaasshh reports an error. Using %%??ccee, on the other hand, refers to + any job containing the string ccee in its command line. If the substring + matches more than one job, bbaasshh reports an error. The symbols %%%% and + %%++ refer to the shell's notion of the _c_u_r_r_e_n_t _j_o_b, which is the last + job stopped while it was in the foreground or started in the back- + ground. The _p_r_e_v_i_o_u_s _j_o_b may be referenced using %%--. In output per- + taining to jobs (e.g., the output of the jjoobbss command), the current job + is always flagged with a ++, and the previous job with a --. A single % + (with no accompanying job specification) also refers to the current + job. + + Simply naming a job can be used to bring it into the foreground: %%11 is + a synonym for ````ffgg %%11'''', bringing job 1 from the background into the + foreground. Similarly, ````%%11 &&'''' resumes job 1 in the background, + equivalent to ````bbgg %%11''''. + + The shell learns immediately whenever a job changes state. Normally, + bbaasshh waits until it is about to print a prompt before reporting changes + in a job's status so as to not interrupt any other output. If the --bb + option to the sseett builtin command is enabled, bbaasshh reports such changes + immediately. Any trap on SSIIGGCCHHLLDD is executed for each child that + exits. + + If an attempt to exit bbaasshh is made while jobs are stopped, the shell + prints a warning message. The jjoobbss command may then be used to inspect + their status.

After the string + is decoded, it is expanded via parameter expansion, command substitu- + tion, arithmetic expansion, and quote removal, subject to the value of + the pprroommppttvvaarrss shell option (see the description of the sshhoopptt command + under SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below). + +RREEAADDLLIINNEE + This is the library that handles reading input when using an interac- + tive shell, unless the ----nnooeeddiittiinngg option is given at shell invocation. + By default, the line editing commands are similar to those of emacs. A + vi-style line editing interface is also available. To turn off line + editing after the shell is running, use the ++oo eemmaaccss or ++oo vvii options + to the sseett builtin (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below). + + RReeaaddlliinnee NNoottaattiioonn + In this section, the emacs-style notation is used to denote keystrokes. + Control keys are denoted by C-_k_e_y, e.g., C-n means Control-N. Simi- + larly, _m_e_t_a keys are denoted by M-_k_e_y, so M-x means Meta-X. (On key- + boards without a _m_e_t_a key, M-_x means ESC _x, i.e., press the Escape key + then the _x key. This makes ESC the _m_e_t_a _p_r_e_f_i_x. The combination M-C-_x + means ESC-Control-_x, or press the Escape key then hold the Control key + while pressing the _x key.) + + Readline commands may be given numeric _a_r_g_u_m_e_n_t_s, which normally act as + a repeat count. Sometimes, however, it is the sign of the argument + that is significant. Passing a negative argument to a command that + acts in the forward direction (e.g., kkiillll--lliinnee) causes that command to + act in a backward direction. Commands whose behavior with arguments + deviates from this are noted below. + + When a command is described as _k_i_l_l_i_n_g text, the text deleted is saved + for possible future retrieval (_y_a_n_k_i_n_g). The killed text is saved in a + _k_i_l_l _r_i_n_g. Consecutive kills cause the text to be accumulated into one + unit, which can be yanked all at once. Commands which do not kill text + separate the chunks of text on the kill ring. + + RReeaaddlliinnee IInniittiiaalliizzaattiioonn + Readline is customized by putting commands in an initialization file + (the _i_n_p_u_t_r_c file). The name of this file is taken from the value of + the IINNPPUUTTRRCC variable. If that variable is unset, the default is + _~_/_._i_n_p_u_t_r_c. When a program which uses the readline library starts up, + the initialization file is read, and the key bindings and variables are + set. There are only a few basic constructs allowed in the readline + initialization file. Blank lines are ignored. Lines beginning with a + ## are comments. Lines beginning with a $$ indicate conditional con- + structs. Other lines denote key bindings and variable settings. + + The default key-bindings may be changed with an _i_n_p_u_t_r_c file. Other + programs that use this library may add their own commands and bindings. + + For example, placing + + M-Control-u: universal-argument + or + C-Meta-u: universal-argument + into the _i_n_p_u_t_r_c would make M-C-u execute the readline command _u_n_i_v_e_r_- + _s_a_l_-_a_r_g_u_m_e_n_t. + + The following symbolic character names are recognized: _R_U_B_O_U_T, _D_E_L, + _E_S_C, _L_F_D, _N_E_W_L_I_N_E, _R_E_T, _R_E_T_U_R_N, _S_P_C, _S_P_A_C_E, and _T_A_B. + + In addition to command names, readline allows keys to be bound to a + string that is inserted when the key is pressed (a _m_a_c_r_o). + + RReeaaddlliinnee KKeeyy BBiinnddiinnggss + The syntax for controlling key bindings in the _i_n_p_u_t_r_c file is simple. + All that is required is the name of the command or the text of a macro + and a key sequence to which it should be bound. The name may be speci- + fied in one of two ways: as a symbolic key name, possibly with _M_e_t_a_- or + _C_o_n_t_r_o_l_- prefixes, or as a key sequence. + + When using the form kkeeyynnaammee:_f_u_n_c_t_i_o_n_-_n_a_m_e or _m_a_c_r_o, _k_e_y_n_a_m_e is the name + of a key spelled out in English. For example: + + Control-u: universal-argument + Meta-Rubout: backward-kill-word + Control-o: "> output" + + In the above example, _C_-_u is bound to the function uunniivveerrssaall--aarrgguummeenntt, + _M_-_D_E_L is bound to the function bbaacckkwwaarrdd--kkiillll--wwoorrdd, and _C_-_o is bound to + run the macro expressed on the right hand side (that is, to insert the + text ``> output'' into the line). + + In the second form, ""kkeeyysseeqq"":_f_u_n_c_t_i_o_n_-_n_a_m_e or _m_a_c_r_o, kkeeyysseeqq differs + from kkeeyynnaammee above in that strings denoting an entire key sequence may + be specified by placing the sequence within double quotes. Some GNU + Emacs style key escapes can be used, as in the following example, but + the symbolic character names are not recognized. + + "\C-u": universal-argument + "\C-x\C-r": re-read-init-file + "\e[11~": "Function Key 1" + + In this example, _C_-_u is again bound to the function uunniivveerrssaall--aarrgguummeenntt. + _C_-_x _C_-_r is bound to the function rree--rreeaadd--iinniitt--ffiillee, and _E_S_C _[ _1 _1 _~ is + bound to insert the text ``Function Key 1''. + + The full set of GNU Emacs style escape sequences is + \\CC-- control prefix + \\MM-- meta prefix + \\ee an escape character + \\\\ backslash + \\"" literal " + \\'' literal ' + + In addition to the GNU Emacs style escape sequences, a second set of + backslash escapes is available: + \\aa alert (bell) + \\bb backspace + \\dd delete + \\ff form feed + \\nn newline + \\rr carriage return + \\tt horizontal tab + \\vv vertical tab + \\_n_n_n the eight-bit character whose value is the octal value + _n_n_n (one to three digits) + \\xx_H_H the eight-bit character whose value is the hexadecimal + value _H_H (one or two hex digits) + + When entering the text of a macro, single or double quotes must be used + to indicate a macro definition.

Unrecognized variable names are ignored. + When a variable value is read, empty or null values, "on" (case-insen- + sitive), and "1" are equivalent to OOnn. All other values are equivalent + to OOffff. The variables and their default values are: + + bbeellll--ssttyyllee ((aauuddiibbllee)) + Controls what happens when readline wants to ring the terminal + bell.

There + are four parser directives used. + + $$iiff The $$iiff construct allows bindings to be made based on the edit- + ing mode, the terminal being used, or the application using + readline. The text of the test extends to the end of the line; + no characters are required to isolate it. + + mmooddee The mmooddee== form of the $$iiff directive is used to test + whether readline is in emacs or vi mode. This may be + used in conjunction with the sseett kkeeyymmaapp command, for + instance, to set bindings in the _e_m_a_c_s_-_s_t_a_n_d_a_r_d and + _e_m_a_c_s_-_c_t_l_x keymaps only if readline is starting out in + emacs mode. + + tteerrmm The tteerrmm== form may be used to include terminal-specific + key bindings, perhaps to bind the key sequences output by + the terminal's function keys. The word on the right side + of the == is tested against the both full name of the ter- + minal and the portion of the terminal name before the + first --. This allows _s_u_n to match both _s_u_n and _s_u_n_-_c_m_d, + for instance. + + aapppplliiccaattiioonn + The aapppplliiccaattiioonn construct is used to include application- + specific settings. Each program using the readline + library sets the _a_p_p_l_i_c_a_t_i_o_n _n_a_m_e, and an initialization + file can test for a particular value. This could be used + to bind key sequences to functions useful for a specific + program. For instance, the following command adds a key + sequence that quotes the current or previous word in + Bash: + + $$iiff Bash + # Quote the current or previous word + "\C-xq": "\eb\"\ef\"" + $$eennddiiff + + $$eennddiiff This command, as seen in the previous example, terminates an $$iiff + command. + + $$eellssee Commands in this branch of the $$iiff directive are executed if the + test fails. + + $$iinncclluuddee + This directive takes a single filename as an argument and reads + commands and bindings from that file. For example, the follow- + ing directive would read _/_e_t_c_/_i_n_p_u_t_r_c: + + $$iinncclluuddee _/_e_t_c_/_i_n_p_u_t_r_c + + SSeeaarrcchhiinngg + Readline provides commands for searching through the command history + (see HHIISSTTOORRYY below) for lines containing a specified string. There are + two search modes: _i_n_c_r_e_m_e_n_t_a_l and _n_o_n_-_i_n_c_r_e_m_e_n_t_a_l. + + Incremental searches begin before the user has finished typing the + search string. As each character of the search string is typed, read- + line displays the next entry from the history matching the string typed + so far. An incremental search requires only as many characters as + needed to find the desired history entry. The characters present in + the value of the iisseeaarrcchh--tteerrmmiinnaattoorrss variable are used to terminate an + incremental search. If that variable has not been assigned a value the + Escape and Control-J characters will terminate an incremental search. + Control-G will abort an incremental search and restore the original + line. When the search is terminated, the history entry containing the + search string becomes the current line. + + To find other matching entries in the history list, type Control-S or + Control-R as appropriate. This will search backward or forward in the + history for the next entry matching the search string typed so far. + Any other key sequence bound to a readline command will terminate the + search and execute that command. For instance, a _n_e_w_l_i_n_e will termi- + nate the search and accept the line, thereby executing the command from + the history list. + + Readline remembers the last incremental search string. If two Control- + Rs are typed without any intervening characters defining a new search + string, any remembered search string is used. + + Non-incremental searches read the entire search string before starting + to search for matching history lines. The search string may be typed + by the user or be part of the contents of the current line. + + RReeaaddlliinnee CCoommmmaanndd NNaammeess + The following is a list of the names of the commands and the default + key sequences to which they are bound.

If a compspec has been defined + for that command, the compspec is used to generate the list of possible + completions for the word. If the command word is a full pathname, a + compspec for the full pathname is searched for first. If no compspec + is found for the full pathname, an attempt is made to find a compspec + for the portion following the final slash. + + Once a compspec has been found, it is used to generate the list of + matching words. If a compspec is not found, the default bbaasshh comple- + tion as described above under CCoommpplleettiinngg is performed. + + First, the actions specified by the compspec are used. Only matches + which are prefixed by the word being completed are returned. When the + --ff or --dd option is used for filename or directory name completion, the + shell variable FFIIGGNNOORREE is used to filter the matches. + + Any completions specified by a filename expansion pattern to the --GG + option are generated next. The words generated by the pattern need not + match the word being completed. The GGLLOOBBIIGGNNOORREE shell variable is not + used to filter the matches, but the FFIIGGNNOORREE variable is used. + + Next, the string specified as the argument to the --WW option is consid- + ered. The string is first split using the characters in the IIFFSS spe- + cial variable as delimiters. Shell quoting is honored. Each word is + then expanded using brace expansion, tilde expansion, parameter and + variable expansion, command substitution, and arithmetic expansion, as + described above under EEXXPPAANNSSIIOONN. The results are split using the rules + described above under WWoorrdd SSpplliittttiinngg. The results of the expansion are + prefix-matched against the word being completed, and the matching words + become the possible completions. + + After these matches have been generated, any shell function or command + specified with the --FF and --CC options is invoked. When the command or + function is invoked, the CCOOMMPP__LLIINNEE and CCOOMMPP__PPOOIINNTT variables are + assigned values as described above under SShheellll VVaarriiaabblleess. If a shell + function is being invoked, the CCOOMMPP__WWOORRDDSS and CCOOMMPP__CCWWOORRDD variables are + also set. When the function or command is invoked, the first argument + is the name of the command whose arguments are being completed, the + second argument is the word being completed, and the third argument is + the word preceding the word being completed on the current command + line. No filtering of the generated completions against the word being + completed is performed; the function or command has complete freedom in + generating the matches. + + Any function specified with --FF is invoked first. The function may use + any of the shell facilities, including the ccoommppggeenn builtin described + below, to generate the matches. It must put the possible completions + in the CCOOMMPPRREEPPLLYY array variable. + + Next, any command specified with the --CC option is invoked in an envi- + ronment equivalent to command substitution. It should print a list of + completions, one per line, to the standard output. Backslash may be + used to escape a newline, if necessary. + + After all of the possible completions are generated, any filter speci- + fied with the --XX option is applied to the list. The filter is a pat- + tern as used for pathname expansion; a && in the pattern is replaced + with the text of the word being completed. A literal && may be escaped + with a backslash; the backslash is removed before attempting a match. + Any completion that matches the pattern will be removed from the list. + A leading !! negates the pattern; in this case any completion not match- + ing the pattern will be removed. + + Finally, any prefix and suffix specified with the --PP and --SS options are + added to each member of the completion list, and the result is returned + to the readline completion code as the list of possible completions. + + If the previously-applied actions do not generate any matches, and the + --oo ddiirrnnaammeess option was supplied to ccoommpplleettee when the compspec was + defined, directory name completion is attempted. + + If the --oo pplluussddiirrss option was supplied to ccoommpplleettee when the compspec + was defined, directory name completion is attempted and any matches are + added to the results of the other actions. + + By default, if a compspec is found, whatever it generates is returned + to the completion code as the full set of possible completions. The + default bbaasshh completions are not attempted, and the readline default of + filename completion is disabled. If the --oo bbaasshhddeeffaauulltt option was sup- + plied to ccoommpplleettee when the compspec was defined, the bbaasshh default com- + pletions are attempted if the compspec generates no matches. If the --oo + ddeeffaauulltt option was supplied to ccoommpplleettee when the compspec was defined, + readline's default completion will be performed if the compspec (and, + if attempted, the default bbaasshh completions) generate no matches. + + When a compspec indicates that directory name completion is desired, + the programmable completion functions force readline to append a slash + to completed names which are symbolic links to directories, subject to + the value of the mmaarrkk--ddiirreeccttoorriieess readline variable, regardless of the + setting of the mmaarrkk--ssyymmlliinnkkeedd--ddiirreeccttoorriieess readline variable. + +HHIISSTTOORRYY + When the --oo hhiissttoorryy option to the sseett builtin is enabled, the shell + provides access to the _c_o_m_m_a_n_d _h_i_s_t_o_r_y, the list of commands previously + typed. The value of the HHIISSTTSSIIZZEE variable is used as the number of + commands to save in a history list. The text of the last HHIISSTTSSIIZZEE com- + mands (default 500) is saved. The shell stores each command in the + history list prior to parameter and variable expansion (see EEXXPPAANNSSIIOONN + above) but after history expansion is performed, subject to the values + of the shell variables HHIISSTTIIGGNNOORREE and HHIISSTTCCOONNTTRROOLL. + + On startup, the history is initialized from the file named by the vari- + able HHIISSTTFFIILLEE (default _~_/_._b_a_s_h___h_i_s_t_o_r_y). The file named by the value + of HHIISSTTFFIILLEE is truncated, if necessary, to contain no more than the + number of lines specified by the value of HHIISSTTFFIILLEESSIIZZEE. When an inter- + active shell exits, the last $$HHIISSTTSSIIZZEE lines are copied from the his- + tory list to $$HHIISSTTFFIILLEE. If the hhiissttaappppeenndd shell option is enabled (see + the description of sshhoopptt under SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below), the lines + are appended to the history file, otherwise the history file is over- + written. If HHIISSTTFFIILLEE is unset, or if the history file is unwritable, + the history is not saved. After saving the history, the history file + is truncated to contain no more than HHIISSTTFFIILLEESSIIZZEE lines. If HHIISSTTFFIILLEE-- + SSIIZZEE is not set, no truncation is performed. + + The builtin command ffcc (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below) may be used + to list or edit and re-execute a portion of the history list. The hhiiss-- + ttoorryy builtin may be used to display or modify the history list and + manipulate the history file. When using command-line editing, search + commands are available in each editing mode that provide access to the + history list. + + The shell allows control over which commands are saved on the history + list. The HHIISSTTCCOONNTTRROOLL and HHIISSTTIIGGNNOORREE variables may be set to cause the + shell to save only a subset of the commands entered. The ccmmddhhiisstt shell + option, if enabled, causes the shell to attempt to save each line of a + multi-line command in the same history entry, adding semicolons where + necessary to preserve syntactic correctness. The lliitthhiisstt shell option + causes the shell to save the command with embedded newlines instead of + semicolons. See the description of the sshhoopptt builtin below under SSHHEELLLL + BBUUIILLTTIINN CCOOMMMMAANNDDSS for information on setting and unsetting shell + options. + +HHIISSTTOORRYY EEXXPPAANNSSIIOONN + The shell supports a history expansion feature that is similar to the + history expansion in ccsshh.. This section describes what syntax features + are available. This feature is enabled by default for interactive + shells, and can be disabled using the ++HH option to the sseett builtin com- + mand (see SSHHEELLLL BBUUIILLTTIINN CCOOMMMMAANNDDSS below). Non-interactive shells do not + perform history expansion by default. + + History expansions introduce words from the history list into the input + stream, making it easy to repeat commands, insert the arguments to a + previous command into the current input line, or fix errors in previous + commands quickly. + + History expansion is performed immediately after a complete line is + read, before the shell breaks it into words. It takes place in two + parts. The first is to determine which line from the history list to + use during substitution. The second is to select portions of that line + for inclusion into the current one. The line selected from the history + is the _e_v_e_n_t, and the portions of that line that are acted upon are + _w_o_r_d_s. Various _m_o_d_i_f_i_e_r_s are available to manipulate the selected + words. The line is broken into words in the same fashion as when read- + ing input, so that several _m_e_t_a_c_h_a_r_a_c_t_e_r-separated words surrounded by + quotes are considered one word. History expansions are introduced by + the appearance of the history expansion character, which is !! by + default. Only backslash (\\) and single quotes can quote the history + expansion character. + + Several characters inhibit history expansion if found immediately fol- + lowing the history expansion character, even if it is unquoted: space, + tab, newline, carriage return, and ==. If the eexxttgglloobb shell option is + enabled, (( will also inhibit expansion. + + Several shell options settable with the sshhoopptt builtin may be used to + tailor the behavior of history expansion. If the hhiissttvveerriiffyy shell + option is enabled (see the description of the sshhoopptt builtin), and rreeaadd-- + lliinnee is being used, history substitutions are not immediately passed to + the shell parser. Instead, the expanded line is reloaded into the + rreeaaddlliinnee editing buffer for further modification. If rreeaaddlliinnee is being + used, and the hhiissttrreeeeddiitt shell option is enabled, a failed history sub- + stitution will be reloaded into the rreeaaddlliinnee editing buffer for correc- + tion. The --pp option to the hhiissttoorryy builtin command may be used to see + what a history expansion will do before using it. The --ss option to the + hhiissttoorryy builtin may be used to add commands to the end of the history + list without actually executing them, so that they are available for + subsequent recall. + + The shell allows control of the various characters used by the history + expansion mechanism (see the description of hhiissttcchhaarrss above under SShheellll + VVaarriiaabblleess). + + EEvveenntt DDeessiiggnnaattoorrss + An event designator is a reference to a command line entry in the his- + tory list. + + !!

If a variable + name is followed by =_w_o_r_d, the value of the variable is set to + _w_o_r_d. eexxppoorrtt returns an exit status of 0 unless an invalid + option is encountered, one of the _n_a_m_e_s is not a valid shell + variable name, or --ff is supplied with a _n_a_m_e that is not a func- + tion. + + ffcc [--ee _e_n_a_m_e] [--nnllrr] [_f_i_r_s_t] [_l_a_s_t] + ffcc --ss [_p_a_t=_r_e_p] [_c_m_d] + Fix Command. In the first form, a range of commands from _f_i_r_s_t + to _l_a_s_t is selected from the history list. _F_i_r_s_t and _l_a_s_t may + be specified as a string (to locate the last command beginning + with that string) or as a number (an index into the history + list, where a negative number is used as an offset from the cur- + rent command number). If _l_a_s_t is not specified it is set to the + current command for listing (so that ``fc -l -10'' prints the + last 10 commands) and to _f_i_r_s_t otherwise. If _f_i_r_s_t is not spec- + ified it is set to the previous command for editing and -16 for + listing. + + The --nn option suppresses the command numbers when listing. The + --rr option reverses the order of the commands. If the --ll option + is given, the commands are listed on standard output. Other- + wise, the editor given by _e_n_a_m_e is invoked on a file containing + those commands. If _e_n_a_m_e is not given, the value of the FFCCEEDDIITT + variable is used, and the value of EEDDIITTOORR if FFCCEEDDIITT is not set. + If neither variable is set, _v_i is used. When editing is com- + plete, the edited commands are echoed and executed. + + In the second form, _c_o_m_m_a_n_d is re-executed after each instance + of _p_a_t is replaced by _r_e_p. A useful alias to use with this is + ``r="fc -s"'', so that typing ``r cc'' runs the last command + beginning with ``cc'' and typing ``r'' re-executes the last com- + mand. + + If the first form is used, the return value is 0 unless an + invalid option is encountered or _f_i_r_s_t or _l_a_s_t specify history + lines out of range. If the --ee option is supplied, the return + value is the value of the last command executed or failure if an + error occurs with the temporary file of commands. If the second + form is used, the return status is that of the command re-exe- + cuted, unless _c_m_d does not specify a valid history line, in + which case ffcc returns failure. + + ffgg [_j_o_b_s_p_e_c] + Resume _j_o_b_s_p_e_c in the foreground, and make it the current job. + If _j_o_b_s_p_e_c is not present, the shell's notion of the _c_u_r_r_e_n_t _j_o_b + is used. The return value is that of the command placed into + the foreground, or failure if run when job control is disabled + or, when run with job control enabled, if _j_o_b_s_p_e_c does not spec- + ify a valid job or _j_o_b_s_p_e_c specifies a job that was started + without job control. + + ggeettooppttss _o_p_t_s_t_r_i_n_g _n_a_m_e [_a_r_g_s] + ggeettooppttss is used by shell procedures to parse positional parame- + ters. _o_p_t_s_t_r_i_n_g contains the option characters to be recog- + nized; if a character is followed by a colon, the option is + expected to have an argument, which should be separated from it + by white space. The colon and question mark characters may not + be used as option characters. Each time it is invoked, ggeettooppttss + places the next option in the shell variable _n_a_m_e, initializing + _n_a_m_e if it does not exist, and the index of the next argument to + be processed into the variable OOPPTTIINNDD. OOPPTTIINNDD is initialized to + 1 each time the shell or a shell script is invoked. When an + option requires an argument, ggeettooppttss places that argument into + the variable OOPPTTAARRGG. The shell does not reset OOPPTTIINNDD automati- + cally; it must be manually reset between multiple calls to + ggeettooppttss within the same shell invocation if a new set of parame- + ters is to be used. + + When the end of options is encountered, ggeettooppttss exits with a + return value greater than zero. OOPPTTIINNDD is set to the index of + the first non-option argument, and nnaammee is set to ?. + + ggeettooppttss normally parses the positional parameters, but if more + arguments are given in _a_r_g_s, ggeettooppttss parses those instead. + + ggeettooppttss can report errors in two ways. If the first character + of _o_p_t_s_t_r_i_n_g is a colon, _s_i_l_e_n_t error reporting is used. In + normal operation diagnostic messages are printed when invalid + options or missing option arguments are encountered. If the + variable OOPPTTEERRRR is set to 0, no error messages will be dis- + played, even if the first character of _o_p_t_s_t_r_i_n_g is not a colon. + + If an invalid option is seen, ggeettooppttss places ? into _n_a_m_e and, if + not silent, prints an error message and unsets OOPPTTAARRGG. If + ggeettooppttss is silent, the option character found is placed in + OOPPTTAARRGG and no diagnostic message is printed. + + If a required argument is not found, and ggeettooppttss is not silent, + a question mark (??) is placed in _n_a_m_e, OOPPTTAARRGG is unset, and a + diagnostic message is printed. If ggeettooppttss is silent, then a + colon (::) is placed in _n_a_m_e and OOPPTTAARRGG is set to the option + character found. + + ggeettooppttss returns true if an option, specified or unspecified, is + found.

If the first argu- + ment is one of the unary conditional operators listed + above under CCOONNDDIITTIIOONNAALL EEXXPPRREESSSSIIOONNSS, the expression is + true if the unary test is true. If the first argument is + not a valid unary conditional operator, the expression is + false. + 3 arguments + If the second argument is one of the binary conditional + operators listed above under CCOONNDDIITTIIOONNAALL EEXXPPRREESSSSIIOONNSS, the + result of the expression is the result of the binary test + using the first and third arguments as operands. If the + first argument is !!, the value is the negation of the + two-argument test using the second and third arguments. + If the first argument is exactly (( and the third argument + is exactly )), the result is the one-argument test of the + second argument. Otherwise, the expression is false. + The --aa and --oo operators are considered binary operators + in this case. + 4 arguments + If the first argument is !!, the result is the negation of + the three-argument expression composed of the remaining + arguments.

The return status is 0. + + ttrraapp [--llpp] [[_a_r_g] _s_i_g_s_p_e_c ...] + The command _a_r_g is to be read and executed when the shell + receives signal(s) _s_i_g_s_p_e_c. If _a_r_g is absent (and there is a + single _s_i_g_s_p_e_c) or --, each specified signal is reset to its + original disposition (the value it had upon entrance to the + shell). If _a_r_g is the null string the signal specified by each + _s_i_g_s_p_e_c is ignored by the shell and by the commands it invokes. + If _a_r_g is not present and --pp has been supplied, then the trap + commands associated with each _s_i_g_s_p_e_c are displayed. If no + arguments are supplied or if only --pp is given, ttrraapp prints the + list of commands associated with each signal. The --ll option + causes the shell to print a list of signal names and their cor- + responding numbers. Each _s_i_g_s_p_e_c is either a signal name + defined in <_s_i_g_n_a_l_._h>, or a signal number. Signal names are + case insensitive and the SIG prefix is optional. If a _s_i_g_s_p_e_c + is EEXXIITT (0) the command _a_r_g is executed on exit from the shell. + If a _s_i_g_s_p_e_c is DDEEBBUUGG, the command _a_r_g is executed before every + _s_i_m_p_l_e _c_o_m_m_a_n_d, _f_o_r command, _c_a_s_e command, _s_e_l_e_c_t command, every + arithmetic _f_o_r command, and before the first command executes in + a shell function (see SSHHEELLLL GGRRAAMMMMAARR above). Refer to the + description of the eexxttddeebbuugg option to the sshhoopptt builtin for + details of its effect on the DDEEBBUUGG trap. If a _s_i_g_s_p_e_c is EERRRR, + the command _a_r_g is executed whenever a simple command has a + non-zero exit status, subject to the following conditions. The + EERRRR trap is not executed if the failed command is part of the + command list immediately following a wwhhiillee or uunnttiill keyword, + part of the test in an _i_f statement, part of a &&&& or |||| list, or + if the command's return value is being inverted via !!. These + are the same conditions obeyed by the eerrrreexxiitt option. If a + _s_i_g_s_p_e_c is RREETTUURRNN, the command _a_r_g is executed each time a shell + function or a script executed with the .. or ssoouurrccee builtins fin- + ishes executing. Signals ignored upon entry to the shell cannot + be trapped or reset. Trapped signals are reset to their origi- + nal values in a child process when it is created. The return + status is false if any _s_i_g_s_p_e_c is invalid; otherwise ttrraapp + returns true. + + ttyyppee [--aaffttppPP] _n_a_m_e [_n_a_m_e ...] + With no options, indicate how each _n_a_m_e would be interpreted if + used as a command name. If the --tt option is used, ttyyppee prints a + string which is one of _a_l_i_a_s, _k_e_y_w_o_r_d, _f_u_n_c_t_i_o_n, _b_u_i_l_t_i_n, or + _f_i_l_e if _n_a_m_e is an alias, shell reserved word, function, + builtin, or disk file, respectively. If the _n_a_m_e is not found, + then nothing is printed, and an exit status of false is + returned. If the --pp option is used, ttyyppee either returns the + name of the disk file that would be executed if _n_a_m_e were speci- + fied as a command name, or nothing if ``type -t name'' would not + return _f_i_l_e. The --PP option forces a PPAATTHH search for each _n_a_m_e, + even if ``type -t name'' would not return _f_i_l_e. If a command is + hashed, --pp and --PP print the hashed value, not necessarily the + file that appears first in PPAATTHH. If the --aa option is used, ttyyppee + prints all of the places that contain an executable named _n_a_m_e. + This includes aliases and functions, if and only if the --pp + option is not also used. The table of hashed commands is not + consulted when using --aa. The --ff option suppresses shell func- + tion lookup, as with the ccoommmmaanndd builtin. ttyyppee returns true if + any of the arguments are found, false if none are found. + + uulliimmiitt [--SSHHaaccddeeffiillmmnnppqqrrssttuuvvxx [_l_i_m_i_t]] + Provides control over the resources available to the shell and + to processes started by it, on systems that allow such control. + The --HH and --SS options specify that the hard or soft limit is set + for the given resource. A hard limit cannot be increased once + it is set; a soft limit may be increased up to the value of the + hard limit. If neither --HH nor --SS is specified, both the soft + and hard limits are set. The value of _l_i_m_i_t can be a number in + the unit specified for the resource or one of the special values + hhaarrdd, ssoofftt, or uunnlliimmiitteedd, which stand for the current hard + limit, the current soft limit, and no limit, respectively. If + _l_i_m_i_t is omitted, the current value of the soft limit of the + resource is printed, unless the --HH option is given. When more + than one resource is specified, the limit name and unit are + printed before the value. Other options are interpreted as fol- + lows: + --aa All current limits are reported + --cc The maximum size of core files created + --dd The maximum size of a process's data segment + --ee The maximum scheduling priority ("nice") + --ff The maximum size of files created by the shell + --ii The maximum number of pending signals + --ll The maximum size that may be locked into memory + --mm The maximum resident set size + --nn The maximum number of open file descriptors (most systems + do not allow this value to be set) + --pp The pipe size in 512-byte blocks (this may not be set) + --qq The maximum number of bytes in POSIX message queues + --rr The maximum real-time scheduling priority + --ss The maximum stack size + --tt The maximum amount of cpu time in seconds + --uu The maximum number of processes available to a single + user + --vv The maximum amount of virtual memory available to the + shell + --xx The maximum number of file locks + + If _l_i_m_i_t is given, it is the new value of the specified resource + (the --aa option is display only). If no option is given, then --ff + is assumed. Values are in 1024-byte increments, except for --tt, + which is in seconds, --pp, which is in units of 512-byte blocks, + and --nn and --uu, which are unscaled values. The return status is + 0 unless an invalid option or argument is supplied, or an error + occurs while setting a new limit. + + uummaasskk [--pp] [--SS] [_m_o_d_e] + The user file-creation mask is set to _m_o_d_e. If _m_o_d_e begins with + a digit, it is interpreted as an octal number; otherwise it is + interpreted as a symbolic mode mask similar to that accepted by + _c_h_m_o_d(1). If _m_o_d_e is omitted, the current value of the mask is + printed. The --SS option causes the mask to be printed in sym- + bolic form; the default output is an octal number. If the --pp + option is supplied, and _m_o_d_e is omitted, the output is in a form + that may be reused as input. The return status is 0 if the mode + was successfully changed or if no _m_o_d_e argument was supplied, + and false otherwise. + + uunnaalliiaass [-aa] [_n_a_m_e ...] + Remove each _n_a_m_e from the list of defined aliases.

+.PD +.SH ARGUMENTS +If arguments remain after option processing, and neither the +.B \-c +nor the +.B \-s +option has been supplied, the first argument is assumed to +be the name of a file containing shell commands. +If +.B bash +is invoked in this fashion, +.B $0 +is set to the name of the file, and the positional parameters +are set to the remaining arguments. +.B Bash +reads and executes commands from this file, then exits. +\fBBash\fP's exit status is the exit status of the last command +executed in the script. +If no commands are executed, the exit status is 0. +An attempt is first made to open the file in the current directory, and, +if no file is found, then the shell searches the directories in +.SM +.B PATH +for the script. +.SH INVOCATION +A \fIlogin shell\fP is one whose first character of argument zero is a +.BR \- , +or one started with the +.B \-\-login +option. +.PP +An \fIinteractive\fP shell is one started without non-option arguments +and without the +.B \-c +option +whose standard input and error are +both connected to terminals (as determined by +.IR isatty (3)), +or one started with the +.B \-i +option. +.SM +.B PS1 +is set and +.B $\- +includes +.B i +if +.B bash +is interactive, +allowing a shell script or a startup file to test this state. +.PP +The following paragraphs describe how +.B bash +executes its startup files. +If any of the files exist but cannot be read, +.B bash +reports an error. +Tildes are expanded in file names as described below under +.B "Tilde Expansion" +in the +.SM +.B EXPANSION +section. +.PP +When +.B bash +is invoked as an interactive login shell, or as a non-interactive shell +with the \fB\-\-login\fP option, it first reads and +executes commands from the file \fI/etc/profile\fP, if that +file exists. +After reading that file, it looks for \fI~/.bash_profile\fP, +\fI~/.bash_login\fP, and \fI~/.profile\fP, in that order, and reads +and executes commands from the first one that exists and is readable. +The +.B \-\-noprofile +option may be used when the shell is started to inhibit this behavior. +.PP +When a login shell exits, +.B bash +reads and executes commands from the file \fI~/.bash_logout\fP, if it +exists. +.PP +When an interactive shell that is not a login shell is started, +.B bash +reads and executes commands from \fI~/.bashrc\fP, if that file exists. +This may be inhibited by using the +.B \-\-norc +option. +The \fB\-\-rcfile\fP \fIfile\fP option will force +.B bash +to read and execute commands from \fIfile\fP instead of \fI~/.bashrc\fP. +.PP +When +.B bash +is started non-interactively, to run a shell script, for example, it +looks for the variable +.SM +.B BASH_ENV +in the environment, expands its value if it appears there, and uses the +expanded value as the name of a file to read and execute. +.B Bash +behaves as if the following command were executed: +.sp .5 +.RS +.if t \f(CWif [ \-n "$BASH_ENV" ]; then . "$BASH_ENV"; fi\fP +.if n if [ \-n "$BASH_ENV" ]; then . "$BASH_ENV"; fi +.RE +.sp .5 +but the value of the +.SM +.B PATH +variable is not used to search for the file name. +.PP +If +.B bash +is invoked with the name +.BR sh , +it tries to mimic the startup behavior of historical versions of +.B sh +as closely as possible, +while conforming to the POSIX standard as well. +When invoked as an interactive login shell, or a non-interactive +shell with the \fB\-\-login\fP option, it first attempts to +read and execute commands from +.I /etc/profile +and +.IR ~/.profile , +in that order. +The +.B \-\-noprofile +option may be used to inhibit this behavior. +When invoked as an interactive shell with the name +.BR sh , +.B bash +looks for the variable +.SM +.BR ENV , +expands its value if it is defined, and uses the +expanded value as the name of a file to read and execute. +Since a shell invoked as +.B sh +does not attempt to read and execute commands from any other startup +files, the +.B \-\-rcfile +option has no effect. +A non-interactive shell invoked with the name +.B sh +does not attempt to read any other startup files. +When invoked as +.BR sh , +.B bash +enters +.I posix +mode after the startup files are read. +.PP +When +.B bash +is started in +.I posix +mode, as with the +.B \-\-posix +command line option, it follows the POSIX standard for startup files. +In this mode, interactive shells expand the +.SM +.B ENV +variable and commands are read and executed from the file +whose name is the expanded value. +No other startup files are read. +.PP +.B Bash +attempts to determine when it is being run by the remote shell +daemon, usually \fIrshd\fP. +If +.B bash +determines it is being run by \fIrshd\fP, it reads and executes +commands from \fI~/.bashrc\fP, if that file exists and is readable. +It will not do this if invoked as \fBsh\fP. +The +.B \-\-norc +option may be used to inhibit this behavior, and the +.B \-\-rcfile +option may be used to force another file to be read, but +\fIrshd\fP does not generally invoke the shell with those options +or allow them to be specified. +.PP +If the shell is started with the effective user (group) id not equal to the +real user (group) id, and the \fB\-p\fP option is not supplied, no startup +files are read, shell functions are not inherited from the environment, the +.SM +.B SHELLOPTS +variable, if it appears in the environment, is ignored, +and the effective user id is set to the real user id. +If the \fB\-p\fP option is supplied at invocation, the startup behavior is +the same, but the effective user id is not reset. +.SH DEFINITIONS +.PP +The following definitions are used throughout the rest of this +document. +.PD 0 +.TP +.B blank +A space or tab. +.TP +.B word +A sequence of characters considered as a single unit by the shell. +Also known as a +.BR token . +.TP +.B name +A +.I word +consisting only of alphanumeric characters and underscores, and +beginning with an alphabetic character or an underscore.

The shell does not wait for the command to +finish, and the return status is 0. Commands separated by a +.B ; +are executed sequentially; the shell waits for each +command to terminate in turn. The return status is the +exit status of the last command executed. +.PP +The control operators +.B && +and +.B \(bv\(bv +denote AND lists and OR lists, respectively. +An AND list has the form +.RS +.PP +\fIcommand1\fP \fB&&\fP \fIcommand2\fP +.RE +.PP +.I command2 +is executed if, and only if, +.I command1 +returns an exit status of zero. +.PP +An OR list has the form +.RS +.PP +\fIcommand1\fP \fB\(bv\(bv\fP \fIcommand2\fP +.PP +.RE +.PP +.I command2 +is executed if and only if +.I command1 +returns a non-zero exit status.

The \fBuntil\fP command is identical +to the \fBwhile\fP command, except that the test is negated; +the +.B do +.I list +is executed as long as the last command in +.I list +returns a non-zero exit status. +The exit status of the \fBwhile\fP and \fBuntil\fP commands +is the exit status +of the last \fBdo\fP \fIlist\fP command executed, or zero if +none was executed. +.SS Shell Function Definitions +.PP +A shell function is an object that is called like a simple command and +executes a compound command with a new set of positional parameters. +Shell functions are declared as follows: +.TP +[ \fBfunction\fP ] \fIname\fP () \fIcompound\-command\fP [\fIredirection\fP] +This defines a function named \fIname\fP. +The reserved word \fBfunction\fP is optional. +If the \fBfunction\fP reserved word is supplied, the parentheses are optional. +The \fIbody\fP of the function is the compound command +.I compound\-command +(see \fBCompound Commands\fP above). +That command is usually a \fIlist\fP of commands between { and }, but +may be any command listed under \fBCompound Commands\fP above. +\fIcompound\-command\fP is executed whenever \fIname\fP is specified as the +name of a simple command. +Any redirections (see +.SM +.B REDIRECTION +below) specified when a function is defined are performed +when the function is executed. +The exit status of a function definition is zero unless a syntax error +occurs or a readonly function with the same name already exists. +When executed, the exit status of a function is the exit status of the +last command executed in the body. (See +.SM +.B FUNCTIONS +below.) +.SH COMMENTS +In a non-interactive shell, or an interactive shell in which the +.B interactive_comments +option to the +.B shopt +builtin is enabled (see +.SM +.B "SHELL BUILTIN COMMANDS" +below), a word beginning with +.B # +causes that word and all remaining characters on that line to +be ignored. An interactive shell without the +.B interactive_comments +option enabled does not allow comments. The +.B interactive_comments +option is on by default in interactive shells. +.SH QUOTING +\fIQuoting\fP is used to remove the special meaning of certain +characters or words to the shell. Quoting can be used to +disable special treatment for special characters, to prevent +reserved words from being recognized as such, and to prevent +parameter expansion. +.PP +Each of the \fImetacharacters\fP listed above under +.SM +.B DEFINITIONS +has special meaning to the shell and must be quoted if it is to +represent itself. +.PP +When the command history expansion facilities are being used +(see +.SM +.B HISTORY EXPANSION +below), the +\fIhistory expansion\fP character, usually \fB!\fP, must be quoted +to prevent history expansion. +.PP +There are three quoting mechanisms: the +.IR "escape character" , +single quotes, and double quotes. +.PP +A non-quoted backslash (\fB\e\fP) is the +.IR "escape character" . +It preserves the literal value of the next character that follows, +with the exception of . If a \fB\e\fP pair +appears, and the backslash is not itself quoted, the \fB\e\fP +is treated as a line continuation (that is, it is removed from the +input stream and effectively ignored). +.PP +Enclosing characters in single quotes preserves the literal value +of each character within the quotes. A single quote may not occur +between single quotes, even when preceded by a backslash. +.PP +Enclosing characters in double quotes preserves the literal value +of all characters within the quotes, with the exception of +.BR $ , +.BR ` , +.BR \e , +and, when history expansion is enabled, +.BR ! . +The characters +.B $ +and +.B ` +retain their special meaning within double quotes. The backslash +retains its special meaning only when followed by one of the following +characters: +.BR $ , +.BR ` , +\^\fB"\fP\^, +.BR \e , +or +.BR . +A double quote may be quoted within double quotes by preceding it with +a backslash. +If enabled, history expansion will be performed unless an +.B ! +appearing in double quotes is escaped using a backslash. +The backslash preceding the +.B ! +is not removed. +.PP +The special parameters +.B * +and +.B @ +have special meaning when in double +quotes (see +.SM +.B PARAMETERS +below). +.PP +Words of the form \fB$\fP\(aq\fIstring\fP\(aq are treated specially. The +word expands to \fIstring\fP, with backslash-escaped characters replaced +as specified by the ANSI C standard. Backslash escape sequences, if +present, are decoded as follows: +.RS +.PD 0 +.TP +.B \ea +alert (bell) +.TP +.B \eb +backspace +.TP +.B \ee +an escape character +.TP +.B \ef +form feed +.TP +.B \en +new line +.TP +.B \er +carriage return +.TP +.B \et +horizontal tab +.TP +.B \ev +vertical tab +.TP +.B \e\e +backslash +.TP +.B \e\(aq +single quote +.TP +.B \e\fInnn\fP +the eight-bit character whose value is the octal value \fInnn\fP +(one to three digits) +.TP +.B \ex\fIHH\fP +the eight-bit character whose value is the hexadecimal value \fIHH\fP +(one or two hex digits) +.TP +.B \ec\fIx\fP +a control-\fIx\fP character +.PD +.RE +.LP +The expanded result is single-quoted, as if the dollar sign had +not been present. +.PP +A double-quoted string preceded by a dollar sign (\fB$\fP) will cause +the string to be translated according to the current locale. +If the current locale is \fBC\fP or \fBPOSIX\fP, the dollar sign +is ignored. +If the string is translated and replaced, the replacement is +double-quoted. +.SH PARAMETERS +A +.I parameter +is an entity that stores values. +It can be a +.IR name , +a number, or one of the special characters listed below under +.BR "Special Parameters" . +A +.I variable +is a parameter denoted by a +.IR name . +A variable has a \fIvalue\fP and zero or more \fIattributes\fP. +Attributes are assigned using the +.B declare +builtin command (see +.B declare +below in +.SM +.BR "SHELL BUILTIN COMMANDS" ). +.PP +A parameter is set if it has been assigned a value. The null string is +a valid value. Once a variable is set, it may be unset only by using +the +.B unset +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.PP +A +.I variable +may be assigned to by a statement of the form +.RS +.PP +\fIname\fP=[\fIvalue\fP] +.RE +.PP +If +.I value +is not given, the variable is assigned the null string. All +.I values +undergo tilde expansion, parameter and variable expansion, +command substitution, arithmetic expansion, and quote +removal (see +.SM +.B EXPANSION +below). If the variable has its +.B integer +attribute set, then +.I value +is evaluated as an arithmetic expression even if the $((...)) expansion is +not used (see +.B "Arithmetic Expansion" +below). +Word splitting is not performed, with the exception +of \fB"$@"\fP as explained below under +.BR "Special Parameters" . +Pathname expansion is not performed. +Assignment statements may also appear as arguments to the +.BR alias , +.BR declare , +.BR typeset , +.BR export , +.BR readonly , +and +.B local +builtin commands. +.PP +In the context where an assignment statement is assigning a value +to a shell variable or array index, the += operator can be used to +append to or add to the variable's previous value. +When += is applied to a variable for which the integer attribute has been +set, \fIvalue\fP is evaluated as an arithmetic expression and added to the +variable's current value, which is also evaluated. +When += is applied to an array variable using compound assignment (see +.B Arrays +below), the +variable's value is not unset (as it is when using =), and new values are +appended to the array beginning at one greater than the array's maximum index. +When applied to a string-valued variable, \fIvalue\fP is expanded and +appended to the variable's value. +.SS Positional Parameters +.PP +A +.I positional parameter +is a parameter denoted by one or more +digits, other than the single digit 0. Positional parameters are +assigned from the shell's arguments when it is invoked, +and may be reassigned using the +.B set +builtin command. Positional parameters may not be assigned to +with assignment statements. The positional parameters are +temporarily replaced when a shell function is executed (see +.SM +.B FUNCTIONS +below). +.PP +When a positional parameter consisting of more than a single +digit is expanded, it must be enclosed in braces (see +.SM +.B EXPANSION +below). +.SS Special Parameters +.PP +The shell treats several parameters specially. These parameters may +only be referenced; assignment to them is not allowed. +.PD 0 +.TP +.B * +Expands to the positional parameters, starting from one. When the +expansion occurs within double quotes, it expands to a single word +with the value of each parameter separated by the first character +of the +.SM +.B IFS +special variable. That is, "\fB$*\fP" is equivalent +to "\fB$1\fP\fIc\fP\fB$2\fP\fIc\fP\fB...\fP", where +.I c +is the first character of the value of the +.SM +.B IFS +variable. If +.SM +.B IFS +is unset, the parameters are separated by spaces. +If +.SM +.B IFS +is null, the parameters are joined without intervening separators. +.TP +.B @ +Expands to the positional parameters, starting from one. When the +expansion occurs within double quotes, each parameter expands to a +separate word. That is, "\fB$@\fP" is equivalent to +"\fB$1\fP" "\fB$2\fP" ... +If the double-quoted expansion occurs within a word, the expansion of +the first parameter is joined with the beginning part of the original +word, and the expansion of the last parameter is joined with the last +part of the original word. +When there are no positional parameters, "\fB$@\fP" and +.B $@ +expand to nothing (i.e., they are removed). +.TP +.B # +Expands to the number of positional parameters in decimal. +.TP +.B ? +Expands to the status of the most recently executed foreground +pipeline. +.TP +.B \- +Expands to the current option flags as specified upon invocation, +by the +.B set +builtin command, or those set by the shell itself +(such as the +.B \-i +option). +.TP +.B $ +Expands to the process ID of the shell. In a () subshell, it +expands to the process ID of the current shell, not the +subshell. +.TP +.B ! +Expands to the process ID of the most recently executed background +(asynchronous) command. +.TP +.B 0 +Expands to the name of the shell or shell script. This is set at +shell initialization. If +.B bash +is invoked with a file of commands, +.B $0 +is set to the name of that file. If +.B bash +is started with the +.B \-c +option, then +.B $0 +is set to the first argument after the string to be +executed, if one is present. Otherwise, it is set +to the file name used to invoke +.BR bash , +as given by argument zero. +.TP +.B _ +At shell startup, set to the absolute pathname used to invoke the +shell or shell script being executed as passed in the environment +or argument list. +Subsequently, expands to the last argument to the previous command, +after expansion. +Also set to the full pathname used to invoke each command executed +and placed in the environment exported to that command. +When checking mail, this parameter holds the name of the mail file +currently being checked. +.PD +.SS Shell Variables +.PP +The following variables are set by the shell: +.PP +.PD 0 +.TP +.B BASH +Expands to the full file name used to invoke this instance of +.BR bash . +.TP +.B BASH_ARGC +An array variable whose values are the number of parameters in each +frame of the current bash execution call stack. +The number of +parameters to the current subroutine (shell function or script executed +with \fB.\fP or \fBsource\fP) is at the top of the stack. +When a subroutine is executed, the number of parameters passed is pushed onto +\fBBASH_ARGC\fP. +The shell sets \fBBASH_ARGC\fP only when in extended debugging mode +(see the description of the +.B extdebug +option to the +.B shopt +builtin below) +.TP +.B BASH_ARGV +An array variable containing all of the parameters in the current bash +execution call stack. The final parameter of the last subroutine call +is at the top of the stack; the first parameter of the initial call is +at the bottom. When a subroutine is executed, the parameters supplied +are pushed onto \fBBASH_ARGV\fP. +The shell sets \fBBASH_ARGV\fP only when in extended debugging mode +(see the description of the +.B extdebug +option to the +.B shopt +builtin below) +.TP +.B BASH_COMMAND +The command currently being executed or about to be executed, unless the +shell is executing a command as the result of a trap, +in which case it is the command executing at the time of the trap. +.TP +.B BASH_EXECUTION_STRING +The command argument to the \fB\-c\fP invocation option. +.TP +.B BASH_LINENO +An array variable whose members are the line numbers in source files +corresponding to each member of \fBFUNCNAME\fP. +\fB${BASH_LINENO[\fP\fI$i\fP\fB]}\fP is the line number in the source +file where \fB${FUNCNAME[\fP\fI$ifP\fB]}\fP was called. +The corresponding source file name is \fB${BASH_SOURCE[\fP\fI$i\fP\fB]}\fB. +Use \fBLINENO\fP to obtain the current line number. +.TP +.B BASH_REMATCH +An array variable whose members are assigned by the \fB=~\fP binary +operator to the \fB[[\fP conditional command. +The element with index 0 is the portion of the string +matching the entire regular expression. +The element with index \fIn\fP is the portion of the +string matching the \fIn\fPth parenthesized subexpression. +This variable is read-only. +.TP +.B BASH_SOURCE +An array variable whose members are the source filenames corresponding +to the elements in the \fBFUNCNAME\fP array variable. +.TP +.B BASH_SUBSHELL +Incremented by one each time a subshell or subshell environment is spawned. +The initial value is 0. +.TP +.B BASH_VERSINFO +A readonly array variable whose members hold version information for +this instance of +.BR bash . +The values assigned to the array members are as follows: +.sp .5 +.RS +.PD 0 +.TP 24 +.B BASH_VERSINFO[\fR0\fP] +The major version number (the \fIrelease\fP). +.TP +.B BASH_VERSINFO[\fR1\fP] +The minor version number (the \fIversion\fP). +.TP +.B BASH_VERSINFO[\fR2\fP] +The patch level. +.TP +.B BASH_VERSINFO[\fR3\fP] +The build version. +.TP +.B BASH_VERSINFO[\fR4\fP] +The release status (e.g., \fIbeta1\fP). +.TP +.B BASH_VERSINFO[\fR5\fP] +The value of \fBMACHTYPE\fP. +.PD +.RE +.TP +.B BASH_VERSION +Expands to a string describing the version of this instance of +.BR bash . +.TP +.B COMP_CWORD +An index into \fB${COMP_WORDS}\fP of the word containing the current +cursor position. +This variable is available only in shell functions invoked by the +programmable completion facilities (see \fBProgrammable Completion\fP +below). +.TP +.B COMP_LINE +The current command line. +This variable is available only in shell functions and external +commands invoked by the +programmable completion facilities (see \fBProgrammable Completion\fP +below). +.TP +.B COMP_POINT +The index of the current cursor position relative to the beginning of +the current command. +If the current cursor position is at the end of the current command, +the value of this variable is equal to \fB${#COMP_LINE}\fP. +This variable is available only in shell functions and external +commands invoked by the +programmable completion facilities (see \fBProgrammable Completion\fP +below). +.TP +.B COMP_WORDBREAKS +The set of characters that the Readline library treats as word +separators when performing word completion. +If +.SM +.B COMP_WORDBREAKS +is unset, it loses its special properties, even if it is +subsequently reset. +.TP +.B COMP_WORDS +An array variable (see \fBArrays\fP below) consisting of the individual +words in the current command line. +This variable is available only in shell functions invoked by the +programmable completion facilities (see \fBProgrammable Completion\fP +below). +.TP +.B DIRSTACK +An array variable (see +.B Arrays +below) containing the current contents of the directory stack. +Directories appear in the stack in the order they are displayed by the +.B dirs +builtin. +Assigning to members of this array variable may be used to modify +directories already in the stack, but the +.B pushd +and +.B popd +builtins must be used to add and remove directories. +Assignment to this variable will not change the current directory. +If +.SM +.B DIRSTACK +is unset, it loses its special properties, even if it is +subsequently reset. +.TP +.B EUID +Expands to the effective user ID of the current user, initialized at +shell startup. This variable is readonly. +.TP +.B FUNCNAME +An array variable containing the names of all shell functions +currently in the execution call stack. +The element with index 0 is the name of any currently-executing +shell function. +The bottom-most element is "main". +This variable exists only when a shell function is executing. +Assignments to +.SM +.B FUNCNAME +have no effect and return an error status. +If +.SM +.B FUNCNAME +is unset, it loses its special properties, even if it is +subsequently reset. +.TP +.B GROUPS +An array variable containing the list of groups of which the current +user is a member. +Assignments to +.SM +.B GROUPS +have no effect and return an error status. +If +.SM +.B GROUPS +is unset, it loses its special properties, even if it is +subsequently reset. +.TP +.B HISTCMD +The history number, or index in the history list, of the current +command. +If +.SM +.B HISTCMD +is unset, it loses its special properties, even if it is +subsequently reset. +.TP +.B HOSTNAME +Automatically set to the name of the current host. +.TP +.B HOSTTYPE +Automatically set to a string that uniquely +describes the type of machine on which +.B bash +is executing. +The default is system-dependent. +.TP +.B LINENO +Each time this parameter is referenced, the shell substitutes +a decimal number representing the current sequential line number +(starting with 1) within a script or function. When not in a +script or function, the value substituted is not guaranteed to +be meaningful. +If +.SM +.B LINENO +is unset, it loses its special properties, even if it is +subsequently reset. +.TP +.B MACHTYPE +Automatically set to a string that fully describes the system +type on which +.B bash +is executing, in the standard GNU \fIcpu-company-system\fP format. +The default is system-dependent. +.TP +.B OLDPWD +The previous working directory as set by the +.B cd +command. +.TP +.B OPTARG +The value of the last option argument processed by the +.B getopts +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.TP +.B OPTIND +The index of the next argument to be processed by the +.B getopts +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.TP +.B OSTYPE +Automatically set to a string that +describes the operating system on which +.B bash +is executing. +The default is system-dependent. +.TP +.B PIPESTATUS +An array variable (see +.B Arrays +below) containing a list of exit status values from the processes +in the most-recently-executed foreground pipeline (which may +contain only a single command). +.TP +.B PPID +The process ID of the shell's parent. This variable is readonly. +.TP +.B PWD +The current working directory as set by the +.B cd +command. +.TP +.B RANDOM +Each time this parameter is referenced, a random integer between +0 and 32767 is +generated. The sequence of random numbers may be initialized by assigning +a value to +.SM +.BR RANDOM . +If +.SM +.B RANDOM +is unset, it loses its special properties, even if it is +subsequently reset. +.TP +.B REPLY +Set to the line of input read by the +.B read +builtin command when no arguments are supplied. +.TP +.B SECONDS +Each time this parameter is +referenced, the number of seconds since shell invocation is returned. If a +value is assigned to +.SM +.BR SECONDS , +the value returned upon subsequent +references is +the number of seconds since the assignment plus the value assigned. +If +.SM +.B SECONDS +is unset, it loses its special properties, even if it is +subsequently reset. +.TP +.B SHELLOPTS +A colon-separated list of enabled shell options. Each word in +the list is a valid argument for the +.B \-o +option to the +.B set +builtin command (see +.SM +.B "SHELL BUILTIN COMMANDS" +below). The options appearing in +.SM +.B SHELLOPTS +are those reported as +.I on +by \fBset \-o\fP. +If this variable is in the environment when +.B bash +starts up, each shell option in the list will be enabled before +reading any startup files. +This variable is read-only. +.TP +.B SHLVL +Incremented by one each time an instance of +.B bash +is started. +.TP +.B UID +Expands to the user ID of the current user, initialized at shell startup. +This variable is readonly. +.PD +.PP +The following variables are used by the shell. In some cases, +.B bash +assigns a default value to a variable; these cases are noted +below. +.PP +.PD 0 +.TP +.B BASH_ENV +If this parameter is set when \fBbash\fP is executing a shell script, +its value is interpreted as a filename containing commands to +initialize the shell, as in +.IR ~/.bashrc . +The value of +.SM +.B BASH_ENV +is subjected to parameter expansion, command substitution, and arithmetic +expansion before being interpreted as a file name. +.SM +.B PATH +is not used to search for the resultant file name. +.TP +.B CDPATH +The search path for the +.B cd +command. +This is a colon-separated list of directories in which the shell looks +for destination directories specified by the +.B cd +command. +A sample value is +.if t \f(CW".:~:/usr"\fP. +.if n ".:~:/usr". +.TP +.B COLUMNS +Used by the \fBselect\fP builtin command to determine the terminal width +when printing selection lists. Automatically set upon receipt of a SIGWINCH. +.TP +.B COMPREPLY +An array variable from which \fBbash\fP reads the possible completions +generated by a shell function invoked by the programmable completion +facility (see \fBProgrammable Completion\fP below). +.TP +.B EMACS +If \fBbash\fP finds this variable in the environment when the shell starts +with value +.if t \f(CWt\fP, +.if n "t", +it assumes that the shell is running in an emacs shell buffer and disables +line editing. +.TP +.B FCEDIT +The default editor for the +.B fc +builtin command. +.TP +.B FIGNORE +A colon-separated list of suffixes to ignore when performing +filename completion (see +.SM +.B READLINE +below). +A filename whose suffix matches one of the entries in +.SM +.B FIGNORE +is excluded from the list of matched filenames. +A sample value is +.if t \f(CW".o:~"\fP. +.if n ".o:~". +.TP +.B GLOBIGNORE +A colon-separated list of patterns defining the set of filenames to +be ignored by pathname expansion. +If a filename matched by a pathname expansion pattern also matches one +of the patterns in +.SM +.BR GLOBIGNORE , +it is removed from the list of matches. +.TP +.B HISTCONTROL +A colon-separated list of values controlling how commands are saved on +the history list. +If the list of values includes +.IR ignorespace , +lines which begin with a +.B space +character are not saved in the history list. +A value of +.I ignoredups +causes lines matching the previous history entry to not be saved. +A value of +.I ignoreboth +is shorthand for \fIignorespace\fP and \fIignoredups\fP. +A value of +.IR erasedups +causes all previous lines matching the current line to be removed from +the history list before that line is saved. +Any value not in the above list is ignored. +If \fBHISTCONTROL\fP is unset, or does not include a valid value, +all lines read by the shell parser are saved on the history list, +subject to the value of +.BR HISTIGNORE . +The second and subsequent lines of a multi-line compound command are +not tested, and are added to the history regardless of the value of +.BR HISTCONTROL . +.TP +.B HISTFILE +The name of the file in which command history is saved (see +.SM +.B HISTORY +below). The default value is \fI~/.bash_history\fP. If unset, the +command history is not saved when an interactive shell exits. +.TP +.B HISTFILESIZE +The maximum number of lines contained in the history file. When this +variable is assigned a value, the history file is truncated, if +necessary, to contain no more than that number of lines. The default +value is 500. The history file is also truncated to this size after +writing it when an interactive shell exits. +.TP +.B HISTIGNORE +A colon-separated list of patterns used to decide which command lines +should be saved on the history list. Each pattern is anchored at the +beginning of the line and must match the complete line (no implicit +`\fB*\fP' is appended). Each pattern is tested against the line +after the checks specified by +.B HISTCONTROL +are applied. +In addition to the normal shell pattern matching characters, `\fB&\fP' +matches the previous history line. `\fB&\fP' may be escaped using a +backslash; the backslash is removed before attempting a match. +The second and subsequent lines of a multi-line compound command are +not tested, and are added to the history regardless of the value of +.BR HISTIGNORE . +.TP +.B HISTSIZE +The number of commands to remember in the command history (see +.SM +.B HISTORY +below). The default value is 500. +.TP +.B HISTTIMEFORMAT +If this variable is set and not null, its value is used as a format string +for \fIstrftime\fP(3) to print the time stamp associated with each history +entry displayed by the \fBhistory\fP builtin. +If this variable is set, time stamps are written to the history file so +they may be preserved across shell sessions. +.TP +.B HOME +The home directory of the current user; the default argument for the +\fBcd\fP builtin command. +The value of this variable is also used when performing tilde expansion. +.TP +.B HOSTFILE +Contains the name of a file in the same format as +.FN /etc/hosts +that should be read when the shell needs to complete a +hostname. +The list of possible hostname completions may be changed while the +shell is running; +the next time hostname completion is attempted after the +value is changed, +.B bash +adds the contents of the new file to the existing list. +If +.SM +.B HOSTFILE +is set, but has no value, \fBbash\fP attempts to read +.FN /etc/hosts +to obtain the list of possible hostname completions. +When +.SM +.B HOSTFILE +is unset, the hostname list is cleared. +.TP +.B IFS +The +.I Internal Field Separator +that is used +for word splitting after expansion and to +split lines into words with the +.B read +builtin command. The default value is +``''. +.TP +.B IGNOREEOF +Controls the +action of an interactive shell on receipt of an +.SM +.B EOF +character as the sole input. If set, the value is the number of +consecutive +.SM +.B EOF +characters which must be +typed as the first characters on an input line before +.B bash +exits. If the variable exists but does not have a numeric value, or +has no value, the default value is 10. If it does not exist, +.SM +.B EOF +signifies the end of input to the shell. +.TP +.B INPUTRC +The filename for the +.B readline +startup file, overriding the default of +.FN ~/.inputrc +(see +.SM +.B READLINE +below). +.TP +.B LANG +Used to determine the locale category for any category not specifically +selected with a variable starting with \fBLC_\fP. +.TP +.B LC_ALL +This variable overrides the value of \fBLANG\fP and any other +\fBLC_\fP variable specifying a locale category. +.TP +.B LC_COLLATE +This variable determines the collation order used when sorting the +results of pathname expansion, and determines the behavior of range +expressions, equivalence classes, and collating sequences within +pathname expansion and pattern matching. +.TP +.B LC_CTYPE +This variable determines the interpretation of characters and the +behavior of character classes within pathname expansion and pattern +matching. +.TP +.B LC_MESSAGES +This variable determines the locale used to translate double-quoted +strings preceded by a \fB$\fP. +.TP +.B LC_NUMERIC +This variable determines the locale category used for number formatting. +.TP +.B LINES +Used by the \fBselect\fP builtin command to determine the column length +for printing selection lists. Automatically set upon receipt of a SIGWINCH. +.TP +.B MAIL +If this parameter is set to a file name and the +.SM +.B MAILPATH +variable is not set, +.B bash +informs the user of the arrival of mail in the specified file. +.TP +.B MAILCHECK +Specifies how +often (in seconds) +.B bash +checks for mail. The default is 60 seconds. When it is time to check +for mail, the shell does so before displaying the primary prompt. +If this variable is unset, or set to a value that is not a number +greater than or equal to zero, the shell disables mail checking. +.TP +.B MAILPATH +A colon-separated list of file names to be checked for mail. +The message to be printed when mail arrives in a particular file +may be specified by separating the file name from the message with a `?'. +When used in the text of the message, \fB$_\fP expands to the name of +the current mailfile. +Example: +.RS +.PP +\fBMAILPATH\fP=\(aq/var/mail/bfox?"You have mail":~/shell\-mail?"$_ has mail!"\(aq +.PP +.B Bash +supplies a default value for this variable, but the location of the user +mail files that it uses is system dependent (e.g., /var/mail/\fB$USER\fP). +.RE +.TP +.B OPTERR +If set to the value 1, +.B bash +displays error messages generated by the +.B getopts +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.SM +.B OPTERR +is initialized to 1 each time the shell is invoked or a shell +script is executed. +.TP +.B PATH +The search path for commands. It +is a colon-separated list of directories in which +the shell looks for commands (see +.SM +.B COMMAND EXECUTION +below). +A zero-length (null) directory name in the value of \fBPATH\fP indicates the +current directory. +A null directory name may appear as two adjacent colons, or as an initial +or trailing colon. +The default path is system-dependent, +and is set by the administrator who installs +.BR bash . +A common value is +.if t \f(CW/usr/gnu/bin:/usr/local/bin:/usr/ucb:/bin:/usr/bin\fP. +.if n ``/usr/gnu/bin:/usr/local/bin:/usr/ucb:/bin:/usr/bin''. +.TP +.B POSIXLY_CORRECT +If this variable is in the environment when \fBbash\fP starts, the shell +enters \fIposix mode\fP before reading the startup files, as if the +.B \-\-posix +invocation option had been supplied. If it is set while the shell is +running, \fBbash\fP enables \fIposix mode\fP, as if the command +.if t \f(CWset -o posix\fP +.if n \fIset -o posix\fP +had been executed. +.TP +.B PROMPT_COMMAND +If set, the value is executed as a command prior to issuing each primary +prompt. +.TP +.B PS1 +The value of this parameter is expanded (see +.SM +.B PROMPTING +below) and used as the primary prompt string. The default value is +``\fB\es\-\ev\e$ \fP''. +.TP +.B PS2 +The value of this parameter is expanded as with +.B PS1 +and used as the secondary prompt string. The default is +``\fB> \fP''. +.TP +.B PS3 +The value of this parameter is used as the prompt for the +.B select +command (see +.SM +.B SHELL GRAMMAR +above). +.TP +.B PS4 +The value of this parameter is expanded as with +.B PS1 +and the value is printed before each command +.B bash +displays during an execution trace. The first character of +.SM +.B PS4 +is replicated multiple times, as necessary, to indicate multiple +levels of indirection. The default is ``\fB+ \fP''. +.TP +.B SHELL +The full pathname to the shell is kept in this environment variable. +If it is not set when the shell starts, +.B bash +assigns to it the full pathname of the current user's login shell. +.TP +.B TIMEFORMAT +The value of this parameter is used as a format string specifying +how the timing information for pipelines prefixed with the +.B time +reserved word should be displayed. +The \fB%\fP character introduces an escape sequence that is +expanded to a time value or other information. +The escape sequences and their meanings are as follows; the +braces denote optional portions. +.sp .5 +.RS +.PD 0 +.TP 10 +.B %% +A literal \fB%\fP. +.TP +.B %[\fIp\fP][l]R +The elapsed time in seconds. +.TP +.B %[\fIp\fP][l]U +The number of CPU seconds spent in user mode. +.TP +.B %[\fIp\fP][l]S +The number of CPU seconds spent in system mode. +.TP +.B %P +The CPU percentage, computed as (%U + %S) / %R. +.PD +.RE +.IP +The optional \fIp\fP is a digit specifying the \fIprecision\fP, +the number of fractional digits after a decimal point. +A value of 0 causes no decimal point or fraction to be output. +At most three places after the decimal point may be specified; +values of \fIp\fP greater than 3 are changed to 3. +If \fIp\fP is not specified, the value 3 is used. +.IP +The optional \fBl\fP specifies a longer format, including +minutes, of the form \fIMM\fPm\fISS\fP.\fIFF\fPs. +The value of \fIp\fP determines whether or not the fraction is +included. +.IP +If this variable is not set, \fBbash\fP acts as if it had the +value \fB$\(aq\enreal\et%3lR\enuser\et%3lU\ensys\t%3lS\(aq\fP. +If the value is null, no timing information is displayed. +A trailing newline is added when the format string is displayed. +.TP +.B TMOUT +If set to a value greater than zero, \fBTMOUT\fP is treated as the +default timeout for the \fBread\fP builtin. +The \fBselect\fP command terminates if input does not arrive +after \fBTMOUT\fP seconds when input is coming from a terminal. +In an interactive shell, the value is interpreted as the +number of seconds to wait for input after issuing the primary prompt. +.B Bash +terminates after waiting for that number of seconds if input does +not arrive. +.TP +.B TMPDIR +If set, \fBBash\fP uses its value as the name of a directory in which +\fBBash\fP creates temporary files for the shell's use. +.TP +.B auto_resume +This variable controls how the shell interacts with the user and +job control. If this variable is set, single word simple +commands without redirections are treated as candidates for resumption +of an existing stopped job. There is no ambiguity allowed; if there is +more than one job beginning with the string typed, the job most recently +accessed is selected. The +.I name +of a stopped job, in this context, is the command line used to +start it. +If set to the value +.IR exact , +the string supplied must match the name of a stopped job exactly; +if set to +.IR substring , +the string supplied needs to match a substring of the name of a +stopped job. The +.I substring +value provides functionality analogous to the +.B %? +job identifier (see +.SM +.B JOB CONTROL +below). If set to any other value, the supplied string must +be a prefix of a stopped job's name; this provides functionality +analogous to the \fB%\fP\fIstring\fP job identifier. +.TP +.B histchars +The two or three characters which control history expansion +and tokenization (see +.SM +.B HISTORY EXPANSION +below). The first character is the \fIhistory expansion\fP character, +the character which signals the start of a history +expansion, normally `\fB!\fP'. +The second character is the \fIquick substitution\fP +character, which is used as shorthand for re-running the previous +command entered, substituting one string for another in the command. +The default is `\fB^\fP'. +The optional third character is the character +which indicates that the remainder of the line is a comment when found +as the first character of a word, normally `\fB#\fP'. The history +comment character causes history substitution to be skipped for the +remaining words on the line. It does not necessarily cause the shell +parser to treat the rest of the line as a comment. +.PD +.SS Arrays +.B Bash +provides one-dimensional array variables. Any variable may be used as +an array; the +.B declare +builtin will explicitly declare an array. There is no maximum +limit on the size of an array, nor any requirement that members +be indexed or assigned contiguously. Arrays are indexed using +integers and are zero-based. +.PP +An array is created automatically if any variable is assigned to using +the syntax \fIname\fP[\fIsubscript\fP]=\fIvalue\fP. The +.I subscript +is treated as an arithmetic expression that must evaluate to a number +greater than or equal to zero. To explicitly declare an array, use +.B declare \-a \fIname\fP +(see +.SM +.B SHELL BUILTIN COMMANDS +below). +.B declare \-a \fIname\fP[\fIsubscript\fP] +is also accepted; the \fIsubscript\fP is ignored. Attributes may be +specified for an array variable using the +.B declare +and +.B readonly +builtins. Each attribute applies to all members of an array. +.PP +Arrays are assigned to using compound assignments of the form +\fIname\fP=\fB(\fPvalue\fI1\fP ... value\fIn\fP\fB)\fP, where each +\fIvalue\fP is of the form [\fIsubscript\fP]=\fIstring\fP. Only +\fIstring\fP is required. If +the optional brackets and subscript are supplied, that index is assigned to; +otherwise the index of the element assigned is the last index assigned +to by the statement plus one. Indexing starts at zero. +This syntax is also accepted by the +.B declare +builtin. Individual array elements may be assigned to using the +\fIname\fP[\fIsubscript\fP]=\fIvalue\fP syntax introduced above. +.PP +Any element of an array may be referenced using +${\fIname\fP[\fIsubscript\fP]}. The braces are required to avoid +conflicts with pathname expansion. If +\fIsubscript\fP is \fB@\fP or \fB*\fP, the word expands to +all members of \fIname\fP. These subscripts differ only when the +word appears within double quotes. If the word is double-quoted, +${\fIname\fP[*]} expands to a single +word with the value of each array member separated by the first +character of the +.SM +.B IFS +special variable, and ${\fIname\fP[@]} expands each element of +\fIname\fP to a separate word. When there are no array members, +${\fIname\fP[@]} expands to nothing. +If the double-quoted expansion occurs within a word, the expansion of +the first parameter is joined with the beginning part of the original +word, and the expansion of the last parameter is joined with the last +part of the original word. +This is analogous to the expansion +of the special parameters \fB*\fP and \fB@\fP (see +.B Special Parameters +above). ${#\fIname\fP[\fIsubscript\fP]} expands to the length of +${\fIname\fP[\fIsubscript\fP]}. If \fIsubscript\fP is \fB*\fP or +\fB@\fP, the expansion is the number of elements in the array. +Referencing an array variable without a subscript is equivalent to +referencing element zero. +.PP +The +.B unset +builtin is used to destroy arrays. \fBunset\fP \fIname\fP[\fIsubscript\fP] +destroys the array element at index \fIsubscript\fP. +Care must be taken to avoid unwanted side effects caused by filename +generation. +\fBunset\fP \fIname\fP, where \fIname\fP is an array, or +\fBunset\fP \fIname\fP[\fIsubscript\fP], where +\fIsubscript\fP is \fB*\fP or \fB@\fP, removes the entire array. +.PP +The +.BR declare , +.BR local , +and +.B readonly +builtins each accept a +.B \-a +option to specify an array. The +.B read +builtin accepts a +.B \-a +option to assign a list of words read from the standard input +to an array. The +.B set +and +.B declare +builtins display array values in a way that allows them to be +reused as assignments. +.SH EXPANSION +Expansion is performed on the command line after it has been split into +words. There are seven kinds of expansion performed: +.IR "brace expansion" , +.IR "tilde expansion" , +.IR "parameter and variable expansion" , +.IR "command substitution" , +.IR "arithmetic expansion" , +.IR "word splitting" , +and +.IR "pathname expansion" . +.PP +The order of expansions is: brace expansion, tilde expansion, +parameter, variable and arithmetic expansion and +command substitution +(done in a left-to-right fashion), word splitting, and pathname +expansion. +.PP +On systems that can support it, there is an additional expansion +available: \fIprocess substitution\fP. +.PP +Only brace expansion, word splitting, and pathname expansion +can change the number of words of the expansion; other expansions +expand a single word to a single word. +The only exceptions to this are the expansions of +"\fB$@\fP" and "\fB${\fP\fIname\fP\fB[@]}\fP" +as explained above (see +.SM +.BR PARAMETERS ). +.SS Brace Expansion +.PP +.I "Brace expansion" +is a mechanism by which arbitrary strings +may be generated. This mechanism is similar to +\fIpathname expansion\fP, but the filenames generated +need not exist. Patterns to be brace expanded take +the form of an optional +.IR preamble , +followed by either a series of comma-separated strings or +a sequence expression between a pair of braces, followed by +an optional +.IR postscript . +The preamble is prefixed to each string contained +within the braces, and the postscript is then appended +to each resulting string, expanding left to right. +.PP +Brace expansions may be nested. The results of each expanded +string are not sorted; left to right order is preserved. +For example, a\fB{\fPd,c,b\fB}\fPe expands into `ade ace abe'. +.PP +A sequence expression takes the form \fB{\fP\fIx\fP\fB..\fP\fIy\fP\fB}\fP, +where \fIx\fP and \fIy\fP are either integers or single characters. +When integers are supplied, the expression expands to each number between +\fIx\fP and \fIy\fP, inclusive. +When characters are supplied, the expression expands to each character +lexicographically between \fIx\fP and \fIy\fP, inclusive. Note that +both \fIx\fP and \fIy\fP must be of the same type. +.PP +Brace expansion is performed before any other expansions, +and any characters special to other expansions are preserved +in the result. It is strictly textual. +.B Bash +does not apply any syntactic interpretation to the context of the +expansion or the text between the braces. +.PP +A correctly-formed brace expansion must contain unquoted opening +and closing braces, and at least one unquoted comma or a valid +sequence expression. +Any incorrectly formed brace expansion is left unchanged. +A \fB{\fP or \fB,\fP may be quoted with a backslash to prevent its +being considered part of a brace expression. +To avoid conflicts with parameter expansion, the string \fB${\fP +is not considered eligible for brace expansion. +.PP +This construct is typically used as shorthand when the common +prefix of the strings to be generated is longer than in the +above example: +.RS +.PP +mkdir /usr/local/src/bash/{old,new,dist,bugs} +.RE +or +.RS +chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}} +.RE +.PP +Brace expansion introduces a slight incompatibility with +historical versions of +.BR sh . +.B sh +does not treat opening or closing braces specially when they +appear as part of a word, and preserves them in the output. +.B Bash +removes braces from words as a consequence of brace +expansion. For example, a word entered to +.B sh +as \fIfile{1,2}\fP +appears identically in the output. The same word is +output as +.I file1 file2 +after expansion by +.BR bash . +If strict compatibility with +.B sh +is desired, start +.B bash +with the +.B +B +option or disable brace expansion with the +.B +B +option to the +.B set +command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.SS Tilde Expansion +.PP +If a word begins with an unquoted tilde character (`\fB~\fP'), all of +the characters preceding the first unquoted slash (or all characters, +if there is no unquoted slash) are considered a \fItilde-prefix\fP. +If none of the characters in the tilde-prefix are quoted, the +characters in the tilde-prefix following the tilde are treated as a +possible \fIlogin name\fP. +If this login name is the null string, the tilde is replaced with the +value of the shell parameter +.SM +.BR HOME . +If +.SM +.B HOME +is unset, the home directory of the user executing the shell is +substituted instead. +Otherwise, the tilde-prefix is replaced with the home directory +associated with the specified login name. +.PP +If the tilde-prefix is a `~+', the value of the shell variable +.SM +.B PWD +replaces the tilde-prefix. +If the tilde-prefix is a `~\-', the value of the shell variable +.SM +.BR OLDPWD , +if it is set, is substituted. +If the characters following the tilde in the tilde-prefix consist +of a number \fIN\fP, optionally prefixed +by a `+' or a `\-', the tilde-prefix is replaced with the corresponding +element from the directory stack, as it would be displayed by the +.B dirs +builtin invoked with the tilde-prefix as an argument. +If the characters following the tilde in the tilde-prefix consist of a +number without a leading `+' or `\-', `+' is assumed. +.PP +If the login name is invalid, or the tilde expansion fails, the word +is unchanged. +.PP +Each variable assignment is checked for unquoted tilde-prefixes immediately +following a +.B : +or the first +.BR = . +In these cases, tilde expansion is also performed. +Consequently, one may use file names with tildes in assignments to +.SM +.BR PATH , +.SM +.BR MAILPATH , +and +.SM +.BR CDPATH , +and the shell assigns the expanded value. +.SS Parameter Expansion +.PP +The `\fB$\fP' character introduces parameter expansion, +command substitution, or arithmetic expansion. The parameter name +or symbol to be expanded may be enclosed in braces, which +are optional but serve to protect the variable to be expanded from +characters immediately following it which could be +interpreted as part of the name. +.PP +When braces are used, the matching ending brace is the first `\fB}\fP' +not escaped by a backslash or within a quoted string, and not within an +embedded arithmetic expansion, command substitution, or parameter +expansion. +.PP +.PD 0 +.TP +${\fIparameter\fP} +The value of \fIparameter\fP is substituted. The braces are required +when +.I parameter +is a positional parameter with more than one digit, +or when +.I parameter +is followed by a character which is not to be +interpreted as part of its name. +.PD +.PP +If the first character of \fIparameter\fP is an exclamation point, +a level of variable indirection is introduced. +\fBBash\fP uses the value of the variable formed from the rest of +\fIparameter\fP as the name of the variable; this variable is then +expanded and that value is used in the rest of the substitution, rather +than the value of \fIparameter\fP itself. +This is known as \fIindirect expansion\fP. +The exceptions to this are the expansions of ${!\fIprefix\fP*} and +${\fB!\fP\fIname\fP[\fI@\fP]} described below. +The exclamation point must immediately follow the left brace in order to +introduce indirection. +.PP +In each of the cases below, \fIword\fP is subject to tilde expansion, +parameter expansion, command substitution, and arithmetic expansion. +When not performing substring expansion, \fBbash\fP tests for a parameter +that is unset or null; omitting the colon results in a test only for a +parameter that is unset. +.PP +.PD 0 +.TP +${\fIparameter\fP\fB:\-\fP\fIword\fP} +\fBUse Default Values\fP. If +.I parameter +is unset or null, the expansion of +.I word +is substituted. Otherwise, the value of +.I parameter +is substituted. +.TP +${\fIparameter\fP\fB:=\fP\fIword\fP} +\fBAssign Default Values\fP. +If +.I parameter +is unset or null, the expansion of +.I word +is assigned to +.IR parameter . +The value of +.I parameter +is then substituted. Positional parameters and special parameters may +not be assigned to in this way. +.TP +${\fIparameter\fP\fB:?\fP\fIword\fP} +\fBDisplay Error if Null or Unset\fP. +If +.I parameter +is null or unset, the expansion of \fIword\fP (or a message to that effect +if +.I word +is not present) is written to the standard error and the shell, if it +is not interactive, exits. Otherwise, the value of \fIparameter\fP is +substituted. +.TP +${\fIparameter\fP\fB:+\fP\fIword\fP} +\fBUse Alternate Value\fP. +If +.I parameter +is null or unset, nothing is substituted, otherwise the expansion of +.I word +is substituted. +.TP +${\fIparameter\fP\fB:\fP\fIoffset\fP} +.PD 0 +.TP +${\fIparameter\fP\fB:\fP\fIoffset\fP\fB:\fP\fIlength\fP} +.PD +\fBSubstring Expansion.\fP +Expands to up to \fIlength\fP characters of \fIparameter\fP +starting at the character specified by \fIoffset\fP. +If \fIlength\fP is omitted, expands to the substring of +\fIparameter\fP starting at the character specified by \fIoffset\fP. +\fIlength\fP and \fIoffset\fP are arithmetic expressions (see +.SM +.B +ARITHMETIC EVALUATION +below). +\fIlength\fP must evaluate to a number greater than or equal to zero. +If \fIoffset\fP evaluates to a number less than zero, the value +is used as an offset from the end of the value of \fIparameter\fP. +If \fIparameter\fP is \fB@\fP, the result is \fIlength\fP positional +parameters beginning at \fIoffset\fP. +If \fIparameter\fP is an array name indexed by @ or *, +the result is the \fIlength\fP +members of the array beginning with ${\fIparameter\fP[\fIoffset\fP]}. +A negative \fIoffset\fP is taken relative to one greater than the maximum +index of the specified array. +Note that a negative offset must be separated from the colon by at least +one space to avoid being confused with the :- expansion. +Substring indexing is zero-based unless the positional parameters +are used, in which case the indexing starts at 1. +.TP +${\fB!\fP\fIprefix\fP\fB*\fP} +.PD 0 +.TP +${\fB!\fP\fIprefix\fP\fB@\fP} +.PD +Expands to the names of variables whose names begin with \fIprefix\fP, +separated by the first character of the +.SM +.B IFS +special variable. +.TP +${\fB!\fP\fIname\fP[\fI@\fP]} +.PD 0 +.TP +${\fB!\fP\fIname\fP[\fI*\fP]} +.PD +If \fIname\fP is an array variable, expands to the list of array indices +(keys) assigned in \fIname\fP. +If \fIname\fP is not an array, expands to 0 if \fIname\fP is set and null +otherwise. +When \fI@\fP is used and the expansion appears within double quotes, each +key expands to a separate word. +.TP +${\fB#\fP\fIparameter\fP} +The length in characters of the value of \fIparameter\fP is substituted. +If +.I parameter +is +.B * +or +.BR @ , +the value substituted is the number of positional parameters. +If +.I parameter +is an array name subscripted by +.B * +or +.BR @ , +the value substituted is the number of elements in the array. +.TP +${\fIparameter\fP\fB#\fP\fIword\fP} +.PD 0 +.TP +${\fIparameter\fP\fB##\fP\fIword\fP} +.PD +The +.I word +is expanded to produce a pattern just as in pathname +expansion.

Normally only the first match is replaced. +If \fIpattern\fP begins with \fB#\fP, it must match at the beginning +of the expanded value of \fIparameter\fP. +If \fIpattern\fP begins with \fB%\fP, it must match at the end +of the expanded value of \fIparameter\fP. +If \fIstring\fP is null, matches of \fIpattern\fP are deleted +and the \fB/\fP following \fIpattern\fP may be omitted. +If +.I parameter +is +.B @ +or +.BR * , +the substitution operation is applied to each positional +parameter in turn, and the expansion is the resultant list. +If +.I parameter +is an array variable subscripted with +.B @ +or +.BR * , +the substitution operation is applied to each member of the +array in turn, and the expansion is the resultant list. +.SS Command Substitution +.PP +\fICommand substitution\fP allows the output of a command to replace +the command name. There are two forms: +.PP +.RS +.PP +\fB$(\fP\fIcommand\fP\|\fB)\fP +.RE +or +.RS +\fB`\fP\fIcommand\fP\fB`\fP +.RE +.PP +.B Bash +performs the expansion by executing \fIcommand\fP and +replacing the command substitution with the standard output of the +command, with any trailing newlines deleted. +Embedded newlines are not deleted, but they may be removed during +word splitting. +The command substitution \fB$(cat \fIfile\fP)\fR can be replaced by +the equivalent but faster \fB$(< \fIfile\fP)\fR. +.PP +When the old-style backquote form of substitution is used, +backslash retains its literal meaning except when followed by +.BR $ , +.BR ` , +or +.BR \e . +The first backquote not preceded by a backslash terminates the +command substitution. +When using the $(\^\fIcommand\fP\|) form, all characters between the +parentheses make up the command; none are treated specially. +.PP +Command substitutions may be nested. To nest when using the backquoted form, +escape the inner backquotes with backslashes. +.PP +If the substitution appears within double quotes, word splitting and +pathname expansion are not performed on the results. +.SS Arithmetic Expansion +.PP +Arithmetic expansion allows the evaluation of an arithmetic expression +and the substitution of the result. The format for arithmetic expansion is: +.RS +.PP +\fB$((\fP\fIexpression\fP\fB))\fP +.RE +.PP +The +.I expression +is treated as if it were within double quotes, but a double quote +inside the parentheses is not treated specially. +All tokens in the expression undergo parameter expansion, string +expansion, command substitution, and quote removal. +Arithmetic expansions may be nested. +.PP +The evaluation is performed according to the rules listed below under +.SM +.BR "ARITHMETIC EVALUATION" . +If +.I expression +is invalid, +.B bash +prints a message indicating failure and no substitution occurs. +.SS Process Substitution +.PP +\fIProcess substitution\fP is supported on systems that support named +pipes (\fIFIFOs\fP) or the \fB/dev/fd\fP method of naming open files. +It takes the form of +\fB<(\fP\fIlist\^\fP\fB)\fP +or +\fB>(\fP\fIlist\^\fP\fB)\fP. +The process \fIlist\fP is run with its input or output connected to a +\fIFIFO\fP or some file in \fB/dev/fd\fP. The name of this file is +passed as an argument to the current command as the result of the +expansion. If the \fB>(\fP\fIlist\^\fP\fB)\fP form is used, writing to +the file will provide input for \fIlist\fP. If the +\fB<(\fP\fIlist\^\fP\fB)\fP form is used, the file passed as an +argument should be read to obtain the output of \fIlist\fP. +.PP +When available, process substitution is performed +simultaneously with parameter and variable expansion, +command substitution, +and arithmetic expansion. +.SS Word Splitting +.PP +The shell scans the results of +parameter expansion, +command substitution, +and +arithmetic expansion +that did not occur within double quotes for +.IR "word splitting" . +.PP +The shell treats each character of +.SM +.B IFS +as a delimiter, and splits the results of the other +expansions into words on these characters. If +.SM +.B IFS +is unset, or its +value is exactly +.BR , +the default, then +any sequence of +.SM +.B IFS +characters serves to delimit words. If +.SM +.B IFS +has a value other than the default, then sequences of +the whitespace characters +.B space +and +.B tab +are ignored at the beginning and end of the +word, as long as the whitespace character is in the +value of +.SM +.BR IFS +(an +.SM +.B IFS +whitespace character). +Any character in +.SM +.B IFS +that is not +.SM +.B IFS +whitespace, along with any adjacent +.SM +.B IFS +whitespace characters, delimits a field. +A sequence of +.SM +.B IFS +whitespace characters is also treated as a delimiter. +If the value of +.SM +.B IFS +is null, no word splitting occurs. +.PP +Explicit null arguments (\^\f3"\^"\fP or \^\f3\(aq\^\(aq\fP\^) are retained. +Unquoted implicit null arguments, resulting from the expansion of +parameters that have no values, are removed. +If a parameter with no value is expanded within double quotes, a +null argument results and is retained. +.PP +Note that if no expansion occurs, no splitting +is performed. +.SS Pathname Expansion +.PP +After word splitting, +unless the +.B \-f +option has been set, +.B bash +scans each word for the characters +.BR * , +.BR ? , +and +.BR [ . +If one of these characters appears, then the word is +regarded as a +.IR pattern , +and replaced with an alphabetically sorted list of +file names matching the pattern. +If no matching file names are found, +and the shell option +.B nullglob +is disabled, the word is left unchanged. +If the +.B nullglob +option is set, and no matches are found, +the word is removed. +If the +.B failglob +shell option is set, and no matches are found, an error message +is printed and the command is not executed. +If the shell option +.B nocaseglob +is enabled, the match is performed without regard to the case +of alphabetic characters. +When a pattern is used for pathname expansion, +the character +.B ``.'' +at the start of a name or immediately following a slash +must be matched explicitly, unless the shell option +.B dotglob +is set. +When matching a pathname, the slash character must always be +matched explicitly. +In other cases, the +.B ``.'' +character is not treated specially. +See the description of +.B shopt +below under +.SM +.B SHELL BUILTIN COMMANDS +for a description of the +.BR nocaseglob , +.BR nullglob , +.BR failglob , +and +.B dotglob +shell options. +.PP +The +.SM +.B GLOBIGNORE +shell variable may be used to restrict the set of file names matching a +.IR pattern . +If +.SM +.B GLOBIGNORE +is set, each matching file name that also matches one of the patterns in +.SM +.B GLOBIGNORE +is removed from the list of matches. +The file names +.B ``.'' +and +.B ``..'' +are always ignored when +.SM +.B GLOBIGNORE +is set and not null. However, setting +.SM +.B GLOBIGNORE +to a non-null value has the effect of enabling the +.B dotglob +shell option, so all other file names beginning with a +.B ``.'' +will match. +To get the old behavior of ignoring file names beginning with a +.BR ``.'' , +make +.B ``.*'' +one of the patterns in +.SM +.BR GLOBIGNORE . +The +.B dotglob +option is disabled when +.SM +.B GLOBIGNORE +is unset. +.PP +\fBPattern Matching\fP +.PP +Any character that appears in a pattern, other than the special pattern +characters described below, matches itself. The NUL character may not +occur in a pattern.

If +.I n +is not specified, the standard output (file descriptor 1) is used. +If the digits in +.I word +do not specify a file descriptor open for output, a redirection error occurs. +As a special case, if \fIn\fP is omitted, and \fIword\fP does not +expand to one or more digits, the standard output and standard +error are redirected as described previously. +.SS "Moving File Descriptors" +.PP +The redirection operator +.RS +.PP +[\fIn\fP]\fB<&\fP\fIdigit\fP\fB\-\fP +.RE +.PP +moves the file descriptor \fIdigit\fP to file descriptor +.IR n , +or the standard input (file descriptor 0) if \fIn\fP is not specified. +\fIdigit\fP is closed after being duplicated to \fIn\fP. +.PP +Similarly, the redirection operator +.RS +.PP +[\fIn\fP]\fB>&\fP\fIdigit\fP\fB\-\fP +.RE +.PP +moves the file descriptor \fIdigit\fP to file descriptor +.IR n , +or the standard output (file descriptor 1) if \fIn\fP is not specified. +.SS "Opening File Descriptors for Reading and Writing" +.PP +The redirection operator +.RS +.PP +[\fIn\fP]\fB<>\fP\fIword\fP +.RE +.PP +causes the file whose name is the expansion of +.I word +to be opened for both reading and writing on file descriptor +.IR n , +or on file descriptor 0 if +.I n +is not specified. If the file does not exist, it is created. +.SH ALIASES +\fIAliases\fP allow a string to be substituted for a word when it is used +as the first word of a simple command. +The shell maintains a list of aliases that may be set and unset with the +.B alias +and +.B unalias +builtin commands (see +.SM +.B SHELL BUILTIN COMMANDS +below). +The first word of each simple command, if unquoted, +is checked to see if it has an +alias. If so, that word is replaced by the text of the alias. +The characters \fB/\fP, \fB$\fP, \fB`\fP, and \fB=\fP and +any of the shell \fImetacharacters\fP or quoting characters +listed above may not appear in an alias name. +The replacement text may contain any valid shell input, +including shell metacharacters. +The first word of the replacement text is tested +for aliases, but a word that is identical to an alias being expanded +is not expanded a second time. +This means that one may alias +.B ls +to +.BR "ls \-F" , +for instance, and +.B bash +does not try to recursively expand the replacement text. +If the last character of the alias value is a +.IR blank , +then the next command +word following the alias is also checked for alias expansion. +.PP +Aliases are created and listed with the +.B alias +command, and removed with the +.B unalias +command. +.PP +There is no mechanism for using arguments in the replacement text. +If arguments are needed, a shell function should be used (see +.SM +.B FUNCTIONS +below). +.PP +Aliases are not expanded when the shell is not interactive, unless +the +.B expand_aliases +shell option is set using +.B shopt +(see the description of +.B shopt +under +.SM +\fBSHELL BUILTIN COMMANDS\fP +below). +.PP +The rules concerning the definition and use of aliases are +somewhat confusing. +.B Bash +always reads at least one complete line +of input before executing any +of the commands on that line. Aliases are expanded when a +command is read, not when it is executed. Therefore, an +alias definition appearing on the same line as another +command does not take effect until the next line of input is read. +The commands following the alias definition +on that line are not affected by the new alias. +This behavior is also an issue when functions are executed. +Aliases are expanded when a function definition is read, +not when the function is executed, because a function definition +is itself a compound command. As a consequence, aliases +defined in a function are not available until after that +function is executed. To be safe, always put +alias definitions on a separate line, and do not use +.B alias +in compound commands. +.PP +For almost every purpose, aliases are superseded by +shell functions. +.SH FUNCTIONS +A shell function, defined as described above under +.SM +.BR "SHELL GRAMMAR" , +stores a series of commands for later execution. +When the name of a shell function is used as a simple command name, +the list of commands associated with that function name is executed. +Functions are executed in the context of the +current shell; no new process is created to interpret +them (contrast this with the execution of a shell script). +When a function is executed, the arguments to the +function become the positional parameters +during its execution. +The special parameter +.B # +is updated to reflect the change. Special parameter 0 +is unchanged. +The first element of the +.SM +.B FUNCNAME +variable is set to the name of the function while the function +is executing. +All other aspects of the shell execution +environment are identical between a function and its caller +with the exception that the +.SM +.B DEBUG +and +.B RETURN +traps (see the description of the +.B trap +builtin under +.SM +.B SHELL BUILTIN COMMANDS +below) are not inherited unless the function has been given the +\fBtrace\fP attribute (see the description of the +.SM +.B declare +builtin below) or the +\fB\-o functrace\fP shell option has been enabled with +the \fBset\fP builtin +(in which case all functions inherit the \fBDEBUG\fP and \fBRETURN\fP traps). +.PP +Variables local to the function may be declared with the +.B local +builtin command. Ordinarily, variables and their values +are shared between the function and its caller. +.PP +If the builtin command +.B return +is executed in a function, the function completes and +execution resumes with the next command after the function +call. +Any command associated with the \fBRETURN\fP trap is executed +before execution resumes. +When a function completes, the values of the +positional parameters and the special parameter +.B # +are restored to the values they had prior to the function's +execution. +.PP +Function names and definitions may be listed with the +.B \-f +option to the +.B declare +or +.B typeset +builtin commands. The +.B \-F +option to +.B declare +or +.B typeset +will list the function names only +(and optionally the source file and line number, if the \fBextdebug\fP +shell option is enabled). +Functions may be exported so that subshells +automatically have them defined with the +.B \-f +option to the +.B export +builtin. +A function definition may be deleted using the \fB\-f\fP option to +the +.B unset +builtin. +Note that shell functions and variables with the same name may result +in multiple identically-named entries in the environment passed to the +shell's children. +Care should be taken in cases where this may cause a problem. +.PP +Functions may be recursive. No limit is imposed on the number +of recursive calls. +.SH "ARITHMETIC EVALUATION" +The shell allows arithmetic expressions to be evaluated, under +certain circumstances (see the \fBlet\fP and \fBdeclare\fP builtin +commands and \fBArithmetic Expansion\fP). +Evaluation is done in fixed-width integers with no check for overflow, +though division by 0 is trapped and flagged as an error. +The operators and their precedence, associativity, and values +are the same as in the C language. +The following list of operators is grouped into levels of +equal-precedence operators. +The levels are listed in order of decreasing precedence. +.PP +.PD 0 +.TP +.B \fIid\fP++ \fIid\fP\-\- +variable post-increment and post-decrement +.TP +.B ++\fIid\fP \-\-\fIid\fP +variable pre-increment and pre-decrement +.TP +.B \- + +unary minus and plus +.TP +.B ! ~ +logical and bitwise negation +.TP +.B ** +exponentiation +.TP +.B * / % +multiplication, division, remainder +.TP +.B + \- +addition, subtraction +.TP +.B << >> +left and right bitwise shifts +.TP +.B <= >= < > +comparison +.TP +.B == != +equality and inequality +.TP +.B & +bitwise AND +.TP +.B ^ +bitwise exclusive OR +.TP +.B | +bitwise OR +.TP +.B && +logical AND +.TP +.B || +logical OR +.TP +.B \fIexpr\fP?\fIexpr\fP:\fIexpr\fP +conditional operator +.TP +.B = *= /= %= += \-= <<= >>= &= ^= |= +assignment +.TP +.B \fIexpr1\fP , \fIexpr2\fP +comma +.PD +.PP +Shell variables are allowed as operands; parameter expansion is +performed before the expression is evaluated. +Within an expression, shell variables may also be referenced by name +without using the parameter expansion syntax. +A shell variable that is null or unset evaluates to 0 when referenced +by name without using the parameter expansion syntax. +The value of a variable is evaluated as an arithmetic expression +when it is referenced, or when a variable which has been given the +\fIinteger\fP attribute using \fBdeclare -i\fP is assigned a value. +A null value evaluates to 0. +A shell variable need not have its integer attribute +turned on to be used in an expression. +.PP +Constants with a leading 0 are interpreted as octal numbers. +A leading 0x or 0X denotes hexadecimal. +Otherwise, numbers take the form [\fIbase#\fP]n, where \fIbase\fP +is a decimal number between 2 and 64 representing the arithmetic +base, and \fIn\fP is a number in that base. +If \fIbase#\fP is omitted, then base 10 is used. +The digits greater than 9 are represented by the lowercase letters, +the uppercase letters, @, and _, in that order. +If \fIbase\fP is less than or equal to 36, lowercase and uppercase +letters may be used interchangeably to represent numbers between 10 +and 35. +.PP +Operators are evaluated in order of precedence. Sub-expressions in +parentheses are evaluated first and may override the precedence +rules above. +.SH "CONDITIONAL EXPRESSIONS" +Conditional expressions are used by the \fB[[\fP compound command and +the \fBtest\fP and \fB[\fP builtin commands to test file attributes +and perform string and arithmetic comparisons. +Expressions are formed from the following unary or binary primaries. +If any \fIfile\fP argument to one of the primaries is of the form +\fI/dev/fd/n\fP, then file descriptor \fIn\fP is checked. +If the \fIfile\fP argument to one of the primaries is one of +\fI/dev/stdin\fP, \fI/dev/stdout\fP, or \fI/dev/stderr\fP, file +descriptor 0, 1, or 2, respectively, is checked. +.PP +Unless otherwise specified, primaries that operate on files follow symbolic +links and operate on the target of the link, rather than the link itself. +.sp 1 +.PD 0 +.TP +.B \-a \fIfile\fP +True if \fIfile\fP exists. +.TP +.B \-b \fIfile\fP +True if \fIfile\fP exists and is a block special file. +.TP +.B \-c \fIfile\fP +True if \fIfile\fP exists and is a character special file. +.TP +.B \-d \fIfile\fP +True if \fIfile\fP exists and is a directory. +.TP +.B \-e \fIfile\fP +True if \fIfile\fP exists. +.TP +.B \-f \fIfile\fP +True if \fIfile\fP exists and is a regular file. +.TP +.B \-g \fIfile\fP +True if \fIfile\fP exists and is set-group-id. +.TP +.B \-h \fIfile\fP +True if \fIfile\fP exists and is a symbolic link. +.TP +.B \-k \fIfile\fP +True if \fIfile\fP exists and its ``sticky'' bit is set. +.TP +.B \-p \fIfile\fP +True if \fIfile\fP exists and is a named pipe (FIFO). +.TP +.B \-r \fIfile\fP +True if \fIfile\fP exists and is readable. +.TP +.B \-s \fIfile\fP +True if \fIfile\fP exists and has a size greater than zero. +.TP +.B \-t \fIfd\fP +True if file descriptor +.I fd +is open and refers to a terminal. +.TP +.B \-u \fIfile\fP +True if \fIfile\fP exists and its set-user-id bit is set. +.TP +.B \-w \fIfile\fP +True if \fIfile\fP exists and is writable. +.TP +.B \-x \fIfile\fP +True if \fIfile\fP exists and is executable. +.TP +.B \-O \fIfile\fP +True if \fIfile\fP exists and is owned by the effective user id. +.TP +.B \-G \fIfile\fP +True if \fIfile\fP exists and is owned by the effective group id. +.TP +.B \-L \fIfile\fP +True if \fIfile\fP exists and is a symbolic link. +.TP +.B \-S \fIfile\fP +True if \fIfile\fP exists and is a socket. +.TP +.B \-N \fIfile\fP +True if \fIfile\fP exists and has been modified since it was last read. +.TP +\fIfile1\fP \-\fBnt\fP \fIfile2\fP +True if \fIfile1\fP is newer (according to modification date) than \fIfile2\fP, +or if \fIfile1\fP exists and \fPfile2\fP does not. +.TP +\fIfile1\fP \-\fBot\fP \fIfile2\fP +True if \fIfile1\fP is older than \fIfile2\fP, or if \fIfile2\fP exists +and \fIfile1\fP does not. +.TP +\fIfile1\fP \fB\-ef\fP \fIfile2\fP +True if \fIfile1\fP and \fIfile2\fP refer to the same device and +inode numbers. +.TP +.B \-o \fIoptname\fP +True if shell option +.I optname +is enabled. +See the list of options under the description of the +.B \-o +option to the +.B set +builtin below. +.TP +.B \-z \fIstring\fP +True if the length of \fIstring\fP is zero. +.TP +\fIstring\fP +.PD 0 +.TP +.B \-n \fIstring\fP +.PD +True if the length of +.I string +is non-zero. +.TP +\fIstring1\fP \fB==\fP \fIstring2\fP +True if the strings are equal. \fB=\fP may be used in place of +\fB==\fP for strict POSIX compliance. +.TP +\fIstring1\fP \fB!=\fP \fIstring2\fP +True if the strings are not equal. +.TP +\fIstring1\fP \fB<\fP \fIstring2\fP +True if \fIstring1\fP sorts before \fIstring2\fP lexicographically +in the current locale. +.TP +\fIstring1\fP \fB>\fP \fIstring2\fP +True if \fIstring1\fP sorts after \fIstring2\fP lexicographically +in the current locale. +.TP +.I \fIarg1\fP \fBOP\fP \fIarg2\fP +.SM +.B OP +is one of +.BR \-eq , +.BR \-ne , +.BR \-lt , +.BR \-le , +.BR \-gt , +or +.BR \-ge . +These arithmetic binary operators return true if \fIarg1\fP +is equal to, not equal to, less than, less than or equal to, +greater than, or greater than or equal to \fIarg2\fP, respectively. +.I Arg1 +and +.I arg2 +may be positive or negative integers. +.PD +.SH "SIMPLE COMMAND EXPANSION" +When a simple command is executed, the shell performs the following +expansions, assignments, and redirections, from left to right. +.IP 1. +The words that the parser has marked as variable assignments (those +preceding the command name) and redirections are saved for later +processing. +.IP 2. +The words that are not variable assignments or redirections are +expanded.

Otherwise, the variables are added to the environment +of the executed command and do not affect the current shell environment. +If any of the assignments attempts to assign a value to a readonly variable, +an error occurs, and the command exits with a non-zero status. +.PP +If no command name results, redirections are performed, but do not +affect the current shell environment. A redirection error causes the +command to exit with a non-zero status. +.PP +If there is a command name left after expansion, execution proceeds as +described below. Otherwise, the command exits. If one of the expansions +contained a command substitution, the exit status of the command is +the exit status of the last command substitution performed. If there +were no command substitutions, the command exits with a status of zero. +.SH "COMMAND EXECUTION" +After a command has been split into words, if it results in a +simple command and an optional list of arguments, the following +actions are taken. +.PP +If the command name contains no slashes, the shell attempts to +locate it. If there exists a shell function by that name, that +function is invoked as described above in +.SM +.BR FUNCTIONS . +If the name does not match a function, the shell searches for +it in the list of shell builtins. If a match is found, that +builtin is invoked. +.PP +If the name is neither a shell function nor a builtin, +and contains no slashes, +.B bash +searches each element of the +.SM +.B PATH +for a directory containing an executable file by that name. +.B Bash +uses a hash table to remember the full pathnames of executable +files (see +.B hash +under +.SM +.B "SHELL BUILTIN COMMANDS" +below). +A full search of the directories in +.SM +.B PATH +is performed only if the command is not found in the hash table. +If the search is unsuccessful, the shell prints an error +message and returns an exit status of 127. +.PP +If the search is successful, or if the command name contains +one or more slashes, the shell executes the named program in a +separate execution environment. +Argument 0 is set to the name given, and the remaining arguments +to the command are set to the arguments given, if any. +.PP +If this execution fails because the file is not in executable +format, and the file is not a directory, it is assumed to be +a \fIshell script\fP, a file +containing shell commands.

Changes made to the subshell environment +cannot affect the shell's execution environment. +.PP +If a command is followed by a \fB&\fP and job control is not active, the +default standard input for the command is the empty file \fI/dev/null\fP. +Otherwise, the invoked command inherits the file descriptors of the calling +shell as modified by redirections. +.SH ENVIRONMENT +When a program is invoked it is given an array of strings +called the +.IR environment . +This is a list of +\fIname\fP\-\fIvalue\fP pairs, of the form +.IR "name\fR=\fPvalue" . +.PP +The shell provides several ways to manipulate the environment. +On invocation, the shell scans its own environment and +creates a parameter for each name found, automatically marking +it for +.I export +to child processes. Executed commands inherit the environment. +The +.B export +and +.B declare \-x +commands allow parameters and functions to be added to and +deleted from the environment. If the value of a parameter +in the environment is modified, the new value becomes part +of the environment, replacing the old. The environment +inherited by any executed command consists of the shell's +initial environment, whose values may be modified in the shell, +less any pairs removed by the +.B unset +command, plus any additions via the +.B export +and +.B declare \-x +commands. +.PP +The environment for any +.I simple command +or function may be augmented temporarily by prefixing it with +parameter assignments, as described above in +.SM +.BR PARAMETERS . +These assignment statements affect only the environment seen +by that command. +.PP +If the +.B \-k +option is set (see the +.B set +builtin command below), then +.I all +parameter assignments are placed in the environment for a command, +not just those that precede the command name. +.PP +When +.B bash +invokes an external command, the variable +.B _ +is set to the full file name of the command and passed to that +command in its environment. +.SH "EXIT STATUS" +For the shell's purposes, a command which exits with a +zero exit status has succeeded. An exit status of zero +indicates success. A non-zero exit status indicates failure. +When a command terminates on a fatal signal \fIN\fP, \fBbash\fP uses +the value of 128+\fIN\fP as the exit status. +.PP +If a command is not found, the child process created to +execute it returns a status of 127. If a command is found +but is not executable, the return status is 126. +.PP +If a command fails because of an error during expansion or redirection, +the exit status is greater than zero. +.PP +Shell builtin commands return a status of 0 (\fItrue\fP) if +successful, and non-zero (\fIfalse\fP) if an error occurs +while they execute. +All builtins return an exit status of 2 to indicate incorrect usage. +.PP +\fBBash\fP itself returns the exit status of the last command +executed, unless a syntax error occurs, in which case it exits +with a non-zero value. See also the \fBexit\fP builtin +command below. +.SH SIGNALS +When \fBbash\fP is interactive, in the absence of any traps, it ignores +.SM +.B SIGTERM +(so that \fBkill 0\fP does not kill an interactive shell), +and +.SM +.B SIGINT +is caught and handled (so that the \fBwait\fP builtin is interruptible). +In all cases, \fBbash\fP ignores +.SM +.BR SIGQUIT . +If job control is in effect, +.B bash +ignores +.SM +.BR SIGTTIN , +.SM +.BR SIGTTOU , +and +.SM +.BR SIGTSTP . +.PP +Non-builtin commands run by \fBbash\fP have signal handlers +set to the values inherited by the shell from its parent. +When job control is not in effect, asynchronous commands +ignore +.SM +.B SIGINT +and +.SM +.B SIGQUIT +in addition to these inherited handlers. +Commands run as a result of command substitution ignore the +keyboard-generated job control signals +.SM +.BR SIGTTIN , +.SM +.BR SIGTTOU , +and +.SM +.BR SIGTSTP . +.PP +The shell exits by default upon receipt of a +.SM +.BR SIGHUP . +Before exiting, an interactive shell resends the +.SM +.B SIGHUP +to all jobs, running or stopped. +Stopped jobs are sent +.SM +.B SIGCONT +to ensure that they receive the +.SM +.BR SIGHUP . +To prevent the shell from +sending the signal to a particular job, it should be removed from the +jobs table with the +.B disown +builtin (see +.SM +.B "SHELL BUILTIN COMMANDS" +below) or marked +to not receive +.SM +.B SIGHUP +using +.BR "disown \-h" . +.PP +If the +.B huponexit +shell option has been set with +.BR shopt , +.B bash +sends a +.SM +.B SIGHUP +to all jobs when an interactive login shell exits. +.PP +If \fBbash\fP is waiting for a command to complete and receives a signal +for which a trap has been set, the trap will not be executed until +the command completes. +When \fBbash\fP is waiting for an asynchronous command via the \fBwait\fP +builtin, the reception of a signal for which a trap has been set will +cause the \fBwait\fP builtin to return immediately with an exit status +greater than 128, immediately after which the trap is executed. +.SH "JOB CONTROL" +.I Job control +refers to the ability to selectively stop (\fIsuspend\fP) +the execution of processes and continue (\fIresume\fP) +their execution at a later point. A user typically employs +this facility via an interactive interface supplied jointly +by the system's terminal driver and +.BR bash . +.PP +The shell associates a +.I job +with each pipeline. It keeps a table of currently executing +jobs, which may be listed with the +.B jobs +command. When +.B bash +starts a job asynchronously (in the +.IR background ), +it prints a line that looks like: +.RS +.PP +[1] 25647 +.RE +.PP +indicating that this job is job number 1 and that the process ID +of the last process in the pipeline associated with this job is 25647. +All of the processes in a single pipeline are members of the same job. +.B Bash +uses the +.I job +abstraction as the basis for job control. +.PP +To facilitate the implementation of the user interface to job +control, the operating system maintains the notion of a \fIcurrent terminal +process group ID\fP. Members of this process group (processes whose +process group ID is equal to the current terminal process group ID) +receive keyboard-generated signals such as +.SM +.BR SIGINT . +These processes are said to be in the +.IR foreground . +.I Background +processes are those whose process group ID differs from the terminal's; +such processes are immune to keyboard-generated signals. +Only foreground processes are allowed to read from or write to the +terminal. Background processes which attempt to read from (write to) the +terminal are sent a +.SM +.B SIGTTIN (SIGTTOU) +signal by the terminal driver, +which, unless caught, suspends the process. +.PP +If the operating system on which +.B bash +is running supports +job control, +.B bash +contains facilities to use it. +Typing the +.I suspend +character (typically +.BR ^Z , +Control-Z) while a process is running +causes that process to be stopped and returns control to +.BR bash . +Typing the +.I "delayed suspend" +character (typically +.BR ^Y , +Control-Y) causes the process to be stopped when it +attempts to read input from the terminal, and control to +be returned to +.BR bash . +The user may then manipulate the state of this job, using the +.B bg +command to continue it in the background, the +.B fg +command to continue it in the foreground, or +the +.B kill +command to kill it. A \fB^Z\fP takes effect immediately, +and has the additional side effect of causing pending output +and typeahead to be discarded. +.PP +There are a number of ways to refer to a job in the shell. +The character +.B % +introduces a job name. Job number +.I n +may be referred to as +.BR %n . +A job may also be referred to using a prefix of the name used to +start it, or using a substring that appears in its command line. +For example, +.B %ce +refers to a stopped +.B ce +job. If a prefix matches more than one job, +.B bash +reports an error. Using +.BR %?ce , +on the other hand, refers to any job containing the string +.B ce +in its command line. If the substring matches more than one job, +.B bash +reports an error. The symbols +.B %% +and +.B %+ +refer to the shell's notion of the +.IR "current job" , +which is the last job stopped while it was in +the foreground or started in the background. +The +.I "previous job" +may be referenced using +.BR %\- . +In output pertaining to jobs (e.g., the output of the +.B jobs +command), the current job is always flagged with a +.BR + , +and the previous job with a +.BR \- . +A single % (with no accompanying job specification) also refers to the +current job. +.PP +Simply naming a job can be used to bring it into the +foreground: +.B %1 +is a synonym for +\fB``fg %1''\fP, +bringing job 1 from the background into the foreground. +Similarly, +.B ``%1 &'' +resumes job 1 in the background, equivalent to +\fB``bg %1''\fP. +.PP +The shell learns immediately whenever a job changes state. +Normally, +.B bash +waits until it is about to print a prompt before reporting +changes in a job's status so as to not interrupt +any other output. If the +.B \-b +option to the +.B set +builtin command +is enabled, +.B bash +reports such changes immediately. +Any trap on +.SM +.B SIGCHLD +is executed for each child that exits. +.PP +If an attempt to exit +.B bash +is made while jobs are stopped, the shell prints a warning message. The +.B jobs +command may then be used to inspect their status. +If a second attempt to exit is made without an intervening command, +the shell does not print another warning, and the stopped +jobs are terminated. +.SH PROMPTING +When executing interactively, +.B bash +displays the primary prompt +.SM +.B PS1 +when it is ready to read a command, and the secondary prompt +.SM +.B PS2 +when it needs more input to complete a command. +.B Bash +allows these prompt strings to be customized by inserting a number of +backslash-escaped special characters that are decoded as follows: +.RS +.PD 0 +.TP +.B \ea +an ASCII bell character (07) +.TP +.B \ed +the date in "Weekday Month Date" format (e.g., "Tue May 26") +.TP +.B \eD{\fIformat\fP} +the \fIformat\fP is passed to \fIstrftime\fP(3) and the result is inserted +into the prompt string; an empty \fIformat\fP results in a locale-specific +time representation. The braces are required +.TP +.B \ee +an ASCII escape character (033) +.TP +.B \eh +the hostname up to the first `.' +.TP +.B \eH +the hostname +.TP +.B \ej +the number of jobs currently managed by the shell +.TP +.B \el +the basename of the shell's terminal device name +.TP +.B \en +newline +.TP +.B \er +carriage return +.TP +.B \es +the name of the shell, the basename of +.B $0 +(the portion following the final slash) +.TP +.B \et +the current time in 24-hour HH:MM:SS format +.TP +.B \eT +the current time in 12-hour HH:MM:SS format +.TP +.B \e@ +the current time in 12-hour am/pm format +.TP +.B \eA +the current time in 24-hour HH:MM format +.TP +.B \eu +the username of the current user +.TP +.B \ev +the version of \fBbash\fP (e.g., 2.00) +.TP +.B \eV +the release of \fBbash\fP, version + patch level (e.g., 2.00.0) +.TP +.B \ew +the current working directory, with \fB$HOME\fP abbreviated with a tilde +.TP +.B \eW +the basename of the current working directory, with \fB$HOME\fP +abbreviated with a tilde +.TP +.B \e! +the history number of this command +.TP +.B \e# +the command number of this command +.TP +.B \e$ +if the effective UID is 0, a +.BR # , +otherwise a +.B $ +.TP +.B \e\fInnn\fP +the character corresponding to the octal number \fInnn\fP +.TP +.B \e\e +a backslash +.TP +.B \e[ +begin a sequence of non-printing characters, which could be used to +embed a terminal control sequence into the prompt +.TP +.B \e] +end a sequence of non-printing characters +.PD +.RE +.PP +The command number and the history number are usually different: +the history number of a command is its position in the history +list, which may include commands restored from the history file +(see +.SM +.B HISTORY +below), while the command number is the position in the sequence +of commands executed during the current shell session. +After the string is decoded, it is expanded via +parameter expansion, command substitution, arithmetic +expansion, and quote removal, subject to the value of the +.B promptvars +shell option (see the description of the +.B shopt +command under +.SM +.B "SHELL BUILTIN COMMANDS" +below). +.SH READLINE +This is the library that handles reading input when using an interactive +shell, unless the +.B \-\-noediting +option is given at shell invocation. +By default, the line editing commands are similar to those of emacs. +A vi-style line editing interface is also available. +To turn off line editing after the shell is running, use the +.B +o emacs +or +.B +o vi +options to the +.B set +builtin (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.SS "Readline Notation" +.PP +In this section, the emacs-style notation is used to denote +keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n +means Control\-N. Similarly, +.I meta +keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards +without a +.I meta +key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key +then the +.I x +key. This makes ESC the \fImeta prefix\fP. +The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP, +or press the Escape key +then hold the Control key while pressing the +.I x +key.) +.PP +Readline commands may be given numeric +.IR arguments , +which normally act as a repeat count. +Sometimes, however, it is the sign of the argument that is significant. +Passing a negative argument to a command that acts in the forward +direction (e.g., \fBkill\-line\fP) causes that command to act in a +backward direction. +Commands whose behavior with arguments deviates from this are noted +below. +.PP +When a command is described as \fIkilling\fP text, the text +deleted is saved for possible future retrieval +(\fIyanking\fP). The killed text is saved in a +\fIkill ring\fP. Consecutive kills cause the text to be +accumulated into one unit, which can be yanked all at once. +Commands which do not kill text separate the chunks of text +on the kill ring. +.SS "Readline Initialization" +.PP +Readline is customized by putting commands in an initialization +file (the \fIinputrc\fP file). +The name of this file is taken from the value of the +.SM +.B INPUTRC +variable. If that variable is unset, the default is +.IR ~/.inputrc . +When a program which uses the readline library starts up, the +initialization file is read, and the key bindings and variables +are set. +There are only a few basic constructs allowed in the +readline initialization file. +Blank lines are ignored. +Lines beginning with a \fB#\fP are comments. +Lines beginning with a \fB$\fP indicate conditional constructs. +Other lines denote key bindings and variable settings. +.PP +The default key-bindings may be changed with an +.I inputrc +file. +Other programs that use this library may add their own commands +and bindings. +.PP +For example, placing +.RS +.PP +M\-Control\-u: universal\-argument +.RE +or +.RS +C\-Meta\-u: universal\-argument +.RE +into the +.I inputrc +would make M\-C\-u execute the readline command +.IR universal\-argument . +.PP +The following symbolic character names are recognized: +.IR RUBOUT , +.IR DEL , +.IR ESC , +.IR LFD , +.IR NEWLINE , +.IR RET , +.IR RETURN , +.IR SPC , +.IR SPACE , +and +.IR TAB . +.PP +In addition to command names, readline allows keys to be bound +to a string that is inserted when the key is pressed (a \fImacro\fP). +.SS "Readline Key Bindings" +.PP +The syntax for controlling key bindings in the +.I inputrc +file is simple. All that is required is the name of the +command or the text of a macro and a key sequence to which +it should be bound. The name may be specified in one of two ways: +as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP +prefixes, or as a key sequence. +.PP +When using the form \fBkeyname\fP:\^\fIfunction\-name\fP or \fImacro\fP, +.I keyname +is the name of a key spelled out in English. For example: +.sp +.RS +Control-u: universal\-argument +.br +Meta-Rubout: backward-kill-word +.br +Control-o: "> output" +.RE +.LP +In the above example, +.I C\-u +is bound to the function +.BR universal\-argument , +.I M\-DEL +is bound to the function +.BR backward\-kill\-word , +and +.I C\-o +is bound to run the macro +expressed on the right hand side (that is, to insert the text +.if t \f(CW> output\fP +.if n ``> output'' +into the line). +.PP +In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP, +.B keyseq +differs from +.B keyname +above in that strings denoting +an entire key sequence may be specified by placing the sequence +within double quotes. Some GNU Emacs style key escapes can be +used, as in the following example, but the symbolic character names +are not recognized. +.sp +.RS +"\eC\-u": universal\-argument +.br +"\eC\-x\eC\-r": re\-read\-init\-file +.br +"\ee[11~": "Function Key 1" +.RE +.PP +In this example, +.I C\-u +is again bound to the function +.BR universal\-argument . +.I "C\-x C\-r" +is bound to the function +.BR re\-read\-init\-file , +and +.I "ESC [ 1 1 ~" +is bound to insert the text +.if t \f(CWFunction Key 1\fP. +.if n ``Function Key 1''. +.PP +The full set of GNU Emacs style escape sequences is +.RS +.PD 0 +.TP +.B \eC\- +control prefix +.TP +.B \eM\- +meta prefix +.TP +.B \ee +an escape character +.TP +.B \e\e +backslash +.TP +.B \e" +literal " +.TP +.B \e\(aq +literal \(aq +.RE +.PD +.PP +In addition to the GNU Emacs style escape sequences, a second +set of backslash escapes is available: +.RS +.PD 0 +.TP +.B \ea +alert (bell) +.TP +.B \eb +backspace +.TP +.B \ed +delete +.TP +.B \ef +form feed +.TP +.B \en +newline +.TP +.B \er +carriage return +.TP +.B \et +horizontal tab +.TP +.B \ev +vertical tab +.TP +.B \e\fInnn\fP +the eight-bit character whose value is the octal value \fInnn\fP +(one to three digits) +.TP +.B \ex\fIHH\fP +the eight-bit character whose value is the hexadecimal value \fIHH\fP +(one or two hex digits) +.RE +.PD +.PP +When entering the text of a macro, single or double quotes must +be used to indicate a macro definition. +Unquoted text is assumed to be a function name. +In the macro body, the backslash escapes described above are expanded. +Backslash will quote any other character in the macro text, +including " and \(aq. +.PP +.B Bash +allows the current readline key bindings to be displayed or modified +with the +.B bind +builtin command. The editing mode may be switched during interactive +use by using the +.B \-o +option to the +.B set +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.SS "Readline Variables" +.PP +Readline has variables that can be used to further customize its +behavior. A variable may be set in the +.I inputrc +file with a statement of the form +.RS +.PP +\fBset\fP \fIvariable\-name\fP \fIvalue\fP +.RE +.PP +Except where noted, readline variables can take the values +.B On +or +.B Off +(without regard to case). +Unrecognized variable names are ignored. +When a variable value is read, empty or null values, "on" (case-insensitive), +and "1" are equivalent to \fBOn\fP. All other values are equivalent to +\fBOff\fP. +The variables and their default values are: +.PP +.PD 0 +.TP +.B bell\-style (audible) +Controls what happens when readline wants to ring the terminal bell. +If set to \fBnone\fP, readline never rings the bell. If set to +\fBvisible\fP, readline uses a visible bell if one is available. +If set to \fBaudible\fP, readline attempts to ring the terminal's bell. +.TP +.B bind\-tty\-special\-chars (On) +If set to \fBOn\fP, readline attempts to bind the control characters +treated specially by the kernel's terminal driver to their readline +equivalents. +.TP +.B comment\-begin (``#'') +The string that is inserted when the readline +.B insert\-comment +command is executed. +This command is bound to +.B M\-# +in emacs mode and to +.B # +in vi command mode. +.TP +.B completion\-ignore\-case (Off) +If set to \fBOn\fP, readline performs filename matching and completion +in a case\-insensitive fashion. +.TP +.B completion\-query\-items (100) +This determines when the user is queried about viewing +the number of possible completions +generated by the \fBpossible\-completions\fP command. +It may be set to any integer value greater than or equal to +zero. If the number of possible completions is greater than +or equal to the value of this variable, the user is asked whether +or not he wishes to view them; otherwise they are simply listed +on the terminal. +.TP +.B convert\-meta (On) +If set to \fBOn\fP, readline will convert characters with the +eighth bit set to an ASCII key sequence +by stripping the eighth bit and prefixing an +escape character (in effect, using escape as the \fImeta prefix\fP). +.TP +.B disable\-completion (Off) +If set to \fBOn\fP, readline will inhibit word completion. Completion +characters will be inserted into the line as if they had been +mapped to \fBself-insert\fP. +.TP +.B editing\-mode (emacs) +Controls whether readline begins with a set of key bindings similar +to \fIemacs\fP or \fIvi\fP. +.B editing\-mode +can be set to either +.B emacs +or +.BR vi . +.TP +.B enable\-keypad (Off) +When set to \fBOn\fP, readline will try to enable the application +keypad when it is called. Some systems need this to enable the +arrow keys. +.TP +.B expand\-tilde (Off) +If set to \fBon\fP, tilde expansion is performed when readline +attempts word completion. +.TP +.B history\-preserve\-point (Off) +If set to \fBon\fP, the history code attempts to place point at the +same location on each history line retrieved with \fBprevious-history\fP +or \fBnext-history\fP. +.TP +.B horizontal\-scroll\-mode (Off) +When set to \fBOn\fP, makes readline use a single line for display, +scrolling the input horizontally on a single screen line when it +becomes longer than the screen width rather than wrapping to a new line. +.TP +.B input\-meta (Off) +If set to \fBOn\fP, readline will enable eight-bit input (that is, +it will not strip the high bit from the characters it reads), +regardless of what the terminal claims it can support. The name +.B meta\-flag +is a synonym for this variable. +.TP +.B isearch\-terminators (``C\-[C\-J'') +The string of characters that should terminate an incremental +search without subsequently executing the character as a command. +If this variable has not been given a value, the characters +\fIESC\fP and \fIC\-J\fP will terminate an incremental search. +.TP +.B keymap (emacs) +Set the current readline keymap. The set of valid keymap names is +\fIemacs, emacs\-standard, emacs\-meta, emacs\-ctlx, vi, +vi\-command\fP, and +.IR vi\-insert . +\fIvi\fP is equivalent to \fIvi\-command\fP; \fIemacs\fP is +equivalent to \fIemacs\-standard\fP. The default value is +.IR emacs ; +the value of +.B editing\-mode +also affects the default keymap. +.TP +.B mark\-directories (On) +If set to \fBOn\fP, completed directory names have a slash +appended. +.TP +.B mark\-modified\-lines (Off) +If set to \fBOn\fP, history lines that have been modified are displayed +with a preceding asterisk (\fB*\fP). +.TP +.B mark\-symlinked\-directories (Off) +If set to \fBOn\fP, completed names which are symbolic links to directories +have a slash appended (subject to the value of +\fBmark\-directories\fP). +.TP +.B match\-hidden\-files (On) +This variable, when set to \fBOn\fP, causes readline to match files whose +names begin with a `.' (hidden files) when performing filename +completion, unless the leading `.' is +supplied by the user in the filename to be completed. +.TP +.B output\-meta (Off) +If set to \fBOn\fP, readline will display characters with the +eighth bit set directly rather than as a meta-prefixed escape +sequence. +.TP +.B page\-completions (On) +If set to \fBOn\fP, readline uses an internal \fImore\fP-like pager +to display a screenful of possible completions at a time. +.TP +.B print\-completions\-horizontally (Off) +If set to \fBOn\fP, readline will display completions with matches +sorted horizontally in alphabetical order, rather than down the screen. +.TP +.B show\-all\-if\-ambiguous (Off) +This alters the default behavior of the completion functions. If +set to +.BR on , +words which have more than one possible completion cause the +matches to be listed immediately instead of ringing the bell. +.TP +.B show\-all\-if\-unmodified (Off) +This alters the default behavior of the completion functions in +a fashion similar to \fBshow\-all\-if\-ambiguous\fP. +If set to +.BR on , +words which have more than one possible completion without any +possible partial completion (the possible completions don't share +a common prefix) cause the matches to be listed immediately instead +of ringing the bell. +.TP +.B visible\-stats (Off) +If set to \fBOn\fP, a character denoting a file's type as reported +by \fIstat\fP(2) is appended to the filename when listing possible +completions. +.PD +.SS "Readline Conditional Constructs" +.PP +Readline implements a facility similar in spirit to the conditional +compilation features of the C preprocessor which allows key +bindings and variable settings to be performed as the result +of tests. There are four parser directives used. +.IP \fB$if\fP +The +.B $if +construct allows bindings to be made based on the +editing mode, the terminal being used, or the application using +readline. The text of the test extends to the end of the line; +no characters are required to isolate it. +.RS +.IP \fBmode\fP +The \fBmode=\fP form of the \fB$if\fP directive is used to test +whether readline is in emacs or vi mode. +This may be used in conjunction +with the \fBset keymap\fP command, for instance, to set bindings in +the \fIemacs\-standard\fP and \fIemacs\-ctlx\fP keymaps only if +readline is starting out in emacs mode. +.IP \fBterm\fP +The \fBterm=\fP form may be used to include terminal-specific +key bindings, perhaps to bind the key sequences output by the +terminal's function keys. The word on the right side of the +.B = +is tested against the both full name of the terminal and the portion +of the terminal name before the first \fB\-\fP. This allows +.I sun +to match both +.I sun +and +.IR sun\-cmd , +for instance. +.IP \fBapplication\fP +The \fBapplication\fP construct is used to include +application-specific settings. Each program using the readline +library sets the \fIapplication name\fP, and an initialization +file can test for a particular value. +This could be used to bind key sequences to functions useful for +a specific program. For instance, the following command adds a +key sequence that quotes the current or previous word in Bash: +.sp 1 +.RS +.nf +\fB$if\fP Bash +# Quote the current or previous word +"\eC\-xq": "\eeb\e"\eef\e"" +\fB$endif\fP +.fi +.RE +.RE +.IP \fB$endif\fP +This command, as seen in the previous example, terminates an +\fB$if\fP command. +.IP \fB$else\fP +Commands in this branch of the \fB$if\fP directive are executed if +the test fails. +.IP \fB$include\fP +This directive takes a single filename as an argument and reads commands +and bindings from that file.

If two +Control-Rs are typed without any intervening characters defining a +new search string, any remembered search string is used. +.PP +Non-incremental searches read the entire search string before starting +to search for matching history lines.

the function or command has complete freedom in generating +the matches. +.PP +Any function specified with \fB\-F\fP is invoked first. +The function may use any of the shell facilities, including the +\fBcompgen\fP builtin described below, to generate the matches. +It must put the possible completions in the +.SM +.B COMPREPLY +array variable. +.PP +Next, any command specified with the \fB\-C\fP option is invoked +in an environment equivalent to command substitution. +It should print a list of completions, one per line, to the +standard output. +Backslash may be used to escape a newline, if necessary. +.PP +After all of the possible completions are generated, any filter +specified with the \fB\-X\fP option is applied to the list. +The filter is a pattern as used for pathname expansion; a \fB&\fP +in the pattern is replaced with the text of the word being completed. +A literal \fB&\fP may be escaped with a backslash; the backslash +is removed before attempting a match. +Any completion that matches the pattern will be removed from the list. +A leading \fB!\fP negates the pattern; in this case any completion +not matching the pattern will be removed. +.PP +Finally, any prefix and suffix specified with the \fB\-P\fP and \fB\-S\fP +options are added to each member of the completion list, and the result is +returned to the readline completion code as the list of possible +completions. +.PP +If the previously-applied actions do not generate any matches, and the +\fB\-o dirnames\fP option was supplied to \fBcomplete\fP when the +compspec was defined, directory name completion is attempted. +.PP +If the \fB\-o plusdirs\fP option was supplied to \fBcomplete\fP when the +compspec was defined, directory name completion is attempted and any +matches are added to the results of the other actions. +.PP +By default, if a compspec is found, whatever it generates is returned +to the completion code as the full set of possible completions. +The default \fBbash\fP completions are not attempted, and the readline +default of filename completion is disabled. +If the \fB\-o bashdefault\fP option was supplied to \fBcomplete\fP when +the compspec was defined, the \fBbash\fP default completions are attempted +if the compspec generates no matches. +If the \fB\-o default\fP option was supplied to \fBcomplete\fP when the +compspec was defined, readline's default completion will be performed +if the compspec (and, if attempted, the default \fBbash\fP completions) +generate no matches. +.PP +When a compspec indicates that directory name completion is desired, +the programmable completion functions force readline to append a slash +to completed names which are symbolic links to directories, subject to +the value of the \fBmark\-directories\fP readline variable, regardless +of the setting of the \fBmark-symlinked\-directories\fP readline variable. +.SH HISTORY +When the +.B \-o history +option to the +.B set +builtin is enabled, the shell provides access to the +\fIcommand history\fP, +the list of commands previously typed. +The value of the \fBHISTSIZE\fP variable is used as the +number of commands to save in a history list. +The text of the last +.SM +.B HISTSIZE +commands (default 500) is saved. The shell +stores each command in the history list prior to parameter and +variable expansion (see +.SM +.B EXPANSION +above) but after history expansion is performed, subject to the +values of the shell variables +.SM +.B HISTIGNORE +and +.SM +.BR HISTCONTROL . +.PP +On startup, the history is initialized from the file named by +the variable +.SM +.B HISTFILE +(default \fI~/.bash_history\fP). +The file named by the value of +.SM +.B HISTFILE +is truncated, if necessary, to contain no more than +the number of lines specified by the value of +.SM +.BR HISTFILESIZE . +When an interactive shell exits, the last +.SM +.B $HISTSIZE +lines are copied from the history list to +.SM +.BR $HISTFILE . +If the +.B histappend +shell option is enabled +(see the description of +.B shopt +under +.SM +.B "SHELL BUILTIN COMMANDS" +below), the lines are appended to the history file, +otherwise the history file is overwritten. +If +.SM +.B HISTFILE +is unset, or if the history file is unwritable, the history is +not saved. After saving the history, the history file is truncated +to contain no more than +.SM +.B HISTFILESIZE +lines. If +.SM +.B HISTFILESIZE +is not set, no truncation is performed. +.PP +The builtin command +.B fc +(see +.SM +.B SHELL BUILTIN COMMANDS +below) may be used to list or edit and re-execute a portion of +the history list. +The +.B history +builtin may be used to display or modify the history list and +manipulate the history file. +When using command-line editing, search commands +are available in each editing mode that provide access to the +history list. +.PP +The shell allows control over which commands are saved on the history +list. The +.SM +.B HISTCONTROL +and +.SM +.B HISTIGNORE +variables may be set to cause the shell to save only a subset of the +commands entered. +The +.B cmdhist +shell option, if enabled, causes the shell to attempt to save each +line of a multi-line command in the same history entry, adding +semicolons where necessary to preserve syntactic correctness. +The +.B lithist +shell option causes the shell to save the command with embedded newlines +instead of semicolons. See the description of the +.B shopt +builtin below under +.SM +.B "SHELL BUILTIN COMMANDS" +for information on setting and unsetting shell options. +.SH "HISTORY EXPANSION" +.PP +The shell supports a history expansion feature that +is similar to the history expansion in +.BR csh. +This section describes what syntax features are available. This +feature is enabled by default for interactive shells, and can be +disabled using the +.B \+H +option to the +.B set +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). Non-interactive shells do not perform history expansion +by default. +.PP +History expansions introduce words from the history list into +the input stream, making it easy to repeat commands, insert the +arguments to a previous command into the current input line, or +fix errors in previous commands quickly. +.PP +History expansion is performed immediately after a complete line +is read, before the shell breaks it into words. +It takes place in two parts. +The first is to determine which line from the history list +to use during substitution. +The second is to select portions of that line for inclusion into +the current one. +The line selected from the history is the \fIevent\fP, +and the portions of that line that are acted upon are \fIwords\fP. +Various \fImodifiers\fP are available to manipulate the selected words. +The line is broken into words in the same fashion as when reading input, +so that several \fImetacharacter\fP-separated words surrounded by +quotes are considered one word. +History expansions are introduced by the appearance of the +history expansion character, which is \^\fB!\fP\^ by default. +Only backslash (\^\fB\e\fP\^) and single quotes can quote +the history expansion character. +.PP +Several characters inhibit history expansion if found immediately +following the history expansion character, even if it is unquoted: +space, tab, newline, carriage return, and \fB=\fP. +If the \fBextglob\fP shell option is enabled, \fB(\fP will also +inhibit expansion. +.PP +Several shell options settable with the +.B shopt +builtin may be used to tailor the behavior of history expansion. +If the +.B histverify +shell option is enabled (see the description of the +.B shopt +builtin), and +.B readline +is being used, history substitutions are not immediately passed to +the shell parser. +Instead, the expanded line is reloaded into the +.B readline +editing buffer for further modification. +If +.B readline +is being used, and the +.B histreedit +shell option is enabled, a failed history substitution will be reloaded +into the +.B readline +editing buffer for correction. +The +.B \-p +option to the +.B history +builtin command may be used to see what a history expansion will +do before using it. +The +.B \-s +option to the +.B history +builtin may be used to add commands to the end of the history list +without actually executing them, so that they are available for +subsequent recall. +.PP +The shell allows control of the various characters used by the +history expansion mechanism (see the description of +.B histchars +above under +.BR "Shell Variables" ). +.SS Event Designators +.PP +An event designator is a reference to a command line entry in the +history list. +.PP +.PD 0 +.TP +.B ! +Start a history substitution, except when followed by a +.BR blank , +newline, carriage return, = +or ( (when the \fBextglob\fP shell option is enabled using +the \fBshopt\fP builtin). +.TP +.B !\fIn\fR +Refer to command line +.IR n . +.TP +.B !\-\fIn\fR +Refer to the current command line minus +.IR n . +.TP +.B !! +Refer to the previous command.

(See +.SM +.B FUNCTIONS +below.) +.SH COMMENTS +In a non-interactive shell, or an interactive shell in which the +.B interactive_comments +option to the +.B shopt +builtin is enabled (see +.SM +.B "SHELL BUILTIN COMMANDS" +below), a word beginning with +.B # +causes that word and all remaining characters on that line to +be ignored. An interactive shell without the +.B interactive_comments +option enabled does not allow comments. The +.B interactive_comments +option is on by default in interactive shells. +.SH QUOTING +\fIQuoting\fP is used to remove the special meaning of certain +characters or words to the shell. Quoting can be used to +disable special treatment for special characters, to prevent +reserved words from being recognized as such, and to prevent +parameter expansion. +.PP +Each of the \fImetacharacters\fP listed above under +.SM +.B DEFINITIONS +has special meaning to the shell and must be quoted if it is to +represent itself. +.PP +When the command history expansion facilities are being used, the +\fIhistory expansion\fP character, usually \fB!\fP, must be quoted +to prevent history expansion. +.PP +There are three quoting mechanisms: the +.IR "escape character" , +single quotes, and double quotes. +.PP +A non-quoted backslash (\fB\e\fP) is the +.IR "escape character" . +It preserves the literal value of the next character that follows, +with the exception of . If a \fB\e\fP pair +appears, and the backslash is not itself quoted, the \fB\e\fP +is treated as a line continuation (that is, it is removed from the +input stream and effectively ignored). +.PP +Enclosing characters in single quotes preserves the literal value +of each character within the quotes. A single quote may not occur +between single quotes, even when preceded by a backslash. +.PP +Enclosing characters in double quotes preserves the literal value +of all characters within the quotes, with the exception of +.BR $ , +.BR ` , +and +.BR \e . +The characters +.B $ +and +.B ` +retain their special meaning within double quotes. The backslash +retains its special meaning only when followed by one of the following +characters: +.BR $ , +.BR ` , +\^\fB"\fP\^, +.BR \e , +or +.BR . +A double quote may be quoted within double quotes by preceding it with +a backslash. +When command history is being used, the double quote may not be used to +quote the history expansion character. +.PP +The special parameters +.B * +and +.B @ +have special meaning when in double +quotes (see +.SM +.B PARAMETERS +below). +.PP +Words of the form \fB$\fP'\fIstring\fP' are treated specially. The +word expands to \fIstring\fP, with backslash-escaped characters replaced +as specifed by the ANSI C standard. Backslash escape sequences, if +present, are decoded as follows: +.RS +.PD 0 +.TP +.B \ea +alert (bell) +.TP +.B \eb +backspace +.TP +.B \ee +an escape character +.TP +.B \ef +form feed +.TP +.B \en +new line +.TP +.B \er +carriage return +.TP +.B \et +horizontal tab +.TP +.B \ev +vertical tab +.TP +.B \e\e +backslash +.TP +.B \e' +single quote +.TP +.B \e\fInnn\fP +the eight-bit character whose value is the octal value \fInnn\fP +(one to three digits) +.TP +.B \ex\fIHH\fP +the eight-bit character whose value is the hexadecimal value \fIHH\fP +(one or two hex digits) +.TP +.B \ec\fIx\fP +a control-\fIx\fP character +.PD +.RE +.LP +The expanded result is single-quoted, as if the dollar sign had +not been present. +.PP +A double-quoted string preceded by a dollar sign (\fB$\fP) will cause +the string to be translated according to the current locale. +If the current locale is \fBC\fP or \fBPOSIX\fP, the dollar sign +is ignored. +If the string is translated and replaced, the replacement is +double-quoted. +.SH PARAMETERS +A +.I parameter +is an entity that stores values. +It can be a +.IR name , +a number, or one of the special characters listed below under +.BR "Special Parameters" . +A +.I variable +is a parameter denoted by a +.IR name . +A variable has a \fIvalue\fP and zero or more \fIattributes\fP. +Attributes are assigned using the +.B declare +builtin command (see +.B declare +below in +.SM +.BR "SHELL BUILTIN COMMANDS" ). +.PP +A parameter is set if it has been assigned a value. The null string is +a valid value. Once a variable is set, it may be unset only by using +the +.B unset +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.PP +A +.I variable +may be assigned to by a statement of the form +.RS +.PP +\fIname\fP=[\fIvalue\fP] +.RE +.PP +If +.I value +is not given, the variable is assigned the null string. All +.I values +undergo tilde expansion, parameter and variable expansion, +command substitution, arithmetic expansion, and quote +removal (see +.SM +.B EXPANSION +below). If the variable has its +.B integer +attribute set, then +.I value +is evaluated as an arithmetic expression even if the $((...)) expansion is +not used (see +.B "Arithmetic Expansion" +below). +Word splitting is not performed, with the exception +of \fB"$@"\fP as explained below under +.BR "Special Parameters" . +Pathname expansion is not performed. +Assignment statements may also appear as arguments to the +.BR declare , +.BR typeset , +.BR export , +.BR readonly , +and +.B local +builtin commands. +.SS Positional Parameters +.PP +A +.I positional parameter +is a parameter denoted by one or more +digits, other than the single digit 0. Positional parameters are +assigned from the shell's arguments when it is invoked, +and may be reassigned using the +.B set +builtin command. Positional parameters may not be assigned to +with assignment statements. The positional parameters are +temporarily replaced when a shell function is executed (see +.SM +.B FUNCTIONS +below). +.PP +When a positional parameter consisting of more than a single +digit is expanded, it must be enclosed in braces (see +.SM +.B EXPANSION +below). +.SS Special Parameters +.PP +The shell treats several parameters specially. These parameters may +only be referenced; assignment to them is not allowed. +.PD 0 +.TP +.B * +Expands to the positional parameters, starting from one. When the +expansion occurs within double quotes, it expands to a single word +with the value of each parameter separated by the first character +of the +.SM +.B IFS +special variable. That is, "\fB$*\fP" is equivalent +to "\fB$1\fP\fIc\fP\fB$2\fP\fIc\fP\fB...\fP", where +.I c +is the first character of the value of the +.SM +.B IFS +variable. If +.SM +.B IFS +is unset, the parameters are separated by spaces. +If +.SM +.B IFS +is null, the parameters are joined without intervening separators. +.TP +.B @ +Expands to the positional parameters, starting from one. When the +expansion occurs within double quotes, each parameter expands to a +separate word. That is, "\fB$@\fP" is equivalent to +"\fB$1\fP" "\fB$2\fP" ... +When there are no positional parameters, "\fB$@\fP" and +.B $@ +expand to nothing (i.e., they are removed). +.TP +.B # +Expands to the number of positional parameters in decimal. +.TP +.B ? +Expands to the status of the most recently executed foreground +pipeline. +.TP +.B \- +Expands to the current option flags as specified upon invocation, +by the +.B set +builtin command, or those set by the shell itself +(such as the +.B \-i +option). +.TP +.B $ +Expands to the process ID of the shell. In a () subshell, it +expands to the process ID of the current shell, not the +subshell. +.TP +.B ! +Expands to the process ID of the most recently executed background +(asynchronous) command. +.TP +.B 0 +Expands to the name of the shell or shell script. This is set at +shell initialization. If +.B bash +is invoked with a file of commands, +.B $0 +is set to the name of that file. If +.B bash +is started with the +.B \-c +option, then +.B $0 +is set to the first argument after the string to be +executed, if one is present. Otherwise, it is set +to the file name used to invoke +.BR bash , +as given by argument zero. +.TP +.B _ +At shell startup, set to the absolute file name of the shell or shell +script being executed as passed in the argument list. +Subsequently, expands to the last argument to the previous command, +after expansion. +Also set to the full file name of each command executed and placed in +the environment exported to that command. +When checking mail, this parameter holds the name of the mail file +currently being checked. +.PD +.SS Shell Variables +.PP +The following variables are set by the shell: +.PP +.PD 0 +.TP +.B BASH +Expands to the full file name used to invoke this instance of +.BR bash . +.TP +.B BASH_ARGC +An array variable whose values are the number of parameters in each +frame of the current bash execution call stack.

If it does not exist, +.SM +.B EOF +signifies the end of input to the shell. +.TP +.B INPUTRC +The filename for the +.B readline +startup file, overriding the default of +.FN ~/.inputrc +(see +.SM +.B READLINE +below). +.TP +.B LANG +Used to determine the locale category for any category not specifically +selected with a variable starting with \fBLC_\fP. +.TP +.B LC_ALL +This variable overrides the value of \fBLANG\fP and any other +\fBLC_\fP variable specifying a locale category. +.TP +.B LC_COLLATE +This variable determines the collation order used when sorting the +results of pathname expansion, and determines the behavior of range +expressions, equivalence classes, and collating sequences within +pathname expansion and pattern matching. +.TP +.B LC_CTYPE +This variable determines the interpretation of characters and the +behavior of character classes within pathname expansion and pattern +matching. +.TP +.B LC_MESSAGES +This variable determines the locale used to translate double-quoted +strings preceded by a \fB$\fP. +.TP +.B LC_NUMERIC +This variable determines the locale category used for number formatting. +.TP +.B LINES +Used by the \fBselect\fP builtin command to determine the column length +for printing selection lists. Automatically set upon receipt of a SIGWINCH. +.TP +.B MAIL +If this parameter is set to a file name and the +.SM +.B MAILPATH +variable is not set, +.B bash +informs the user of the arrival of mail in the specified file. +.TP +.B MAILCHECK +Specifies how +often (in seconds) +.B bash +checks for mail. The default is 60 seconds. When it is time to check +for mail, the shell does so before displaying the primary prompt. +If this variable is unset, or set to a value that is not a number +greater than or equal to zero, the shell disables mail checking. +.TP +.B MAILPATH +A colon-separated list of file names to be checked for mail. +The message to be printed when mail arrives in a particular file +may be specified by separating the file name from the message with a `?'. +When used in the text of the message, \fB$_\fP expands to the name of +the current mailfile. +Example: +.RS +.PP +\fBMAILPATH\fP='/var/mail/bfox?"You have mail":~/shell\-mail?"$_ has mail!"' +.PP +.B Bash +supplies a default value for this variable, but the location of the user +mail files that it uses is system dependent (e.g., /var/mail/\fB$USER\fP). +.RE +.TP +.B OPTERR +If set to the value 1, +.B bash +displays error messages generated by the +.B getopts +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.SM +.B OPTERR +is initialized to 1 each time the shell is invoked or a shell +script is executed. +.TP +.B PATH +The search path for commands. It +is a colon-separated list of directories in which +the shell looks for commands (see +.SM +.B COMMAND EXECUTION +below). +A zero-length (null) directory name in the value of \fBPATH\fP indicates the +current directory. +A null directory name may appear as two adjacent colons, or as an initial +or trailing colon. +The default path is system-dependent, +and is set by the administrator who installs +.BR bash . +A common value is +.if t \f(CW/usr/gnu/bin:/usr/local/bin:/usr/ucb:/bin:/usr/bin:.\fP. +.if n ``/usr/gnu/bin:/usr/local/bin:/usr/ucb:/bin:/usr/bin:.''. +.TP +.B POSIXLY_CORRECT +If this variable is in the environment when \fBbash\fP starts, the shell +enters \fIposix mode\fP before reading the startup files, as if the +.B \-\-posix +invocation option had been supplied. If it is set while the shell is +running, \fBbash\fP enables \fIposix mode\fP, as if the command +.if t \f(CWset -o posix\fP +.if n \fIset -o posix\fP +had been executed. +.TP +.B PROMPT_COMMAND +If set, the value is executed as a command prior to issuing each primary +prompt. +.TP +.B PS1 +The value of this parameter is expanded (see +.SM +.B PROMPTING +below) and used as the primary prompt string. The default value is +``\fB\es\-\ev\e$ \fP''. +.TP +.B PS2 +The value of this parameter is expanded as with +.B PS1 +and used as the secondary prompt string. The default is +``\fB> \fP''. +.TP +.B PS3 +The value of this parameter is used as the prompt for the +.B select +command (see +.SM +.B SHELL GRAMMAR +above). +.TP +.B PS4 +The value of this parameter is expanded as with +.B PS1 +and the value is printed before each command +.B bash +displays during an execution trace. The first character of +.SM +.B PS4 +is replicated multiple times, as necessary, to indicate multiple +levels of indirection. The default is ``\fB+ \fP''. +.TP +.B TIMEFORMAT +The value of this parameter is used as a format string specifying +how the timing information for pipelines prefixed with the +.B time +reserved word should be displayed. +The \fB%\fP character introduces an escape sequence that is +expanded to a time value or other information. +The escape sequences and their meanings are as follows; the +braces denote optional portions. +.sp .5 +.RS +.PD 0 +.TP 10 +.B %% +A literal \fB%\fP. +.TP +.B %[\fIp\fP][l]R +The elapsed time in seconds. +.TP +.B %[\fIp\fP][l]U +The number of CPU seconds spent in user mode. +.TP +.B %[\fIp\fP][l]S +The number of CPU seconds spent in system mode. +.TP +.B %P +The CPU percentage, computed as (%U + %S) / %R. +.PD +.RE +.IP +The optional \fIp\fP is a digit specifying the \fIprecision\fP, +the number of fractional digits after a decimal point. +A value of 0 causes no decimal point or fraction to be output. +At most three places after the decimal point may be specified; +values of \fIp\fP greater than 3 are changed to 3. +If \fIp\fP is not specified, the value 3 is used. +.IP +The optional \fBl\fP specifies a longer format, including +minutes, of the form \fIMM\fPm\fISS\fP.\fIFF\fPs. +The value of \fIp\fP determines whether or not the fraction is +included. +.IP +If this variable is not set, \fBbash\fP acts as if it had the +value \fB$'\enreal\et%3lR\enuser\et%3lU\ensys\t%3lS'\fP. +If the value is null, no timing information is displayed. +A trailing newline is added when the format string is displayed. +.TP +.B TMOUT +If set to a value greater than zero, \fBTMOUT\fP is treated as the +default timeout for the \fBread\fP builtin. +The \fBselect\fP command terminates if input does not arrive +after \fBTMOUT\fP seconds when input is coming from a terminal. +In an interactive shell, the value is interpreted as the +number of seconds to wait for input after issuing the primary prompt. +.B Bash +terminates after waiting for that number of seconds if input does +not arrive. +.TP +.B auto_resume +This variable controls how the shell interacts with the user and +job control. If this variable is set, single word simple +commands without redirections are treated as candidates for resumption +of an existing stopped job. There is no ambiguity allowed; if there is +more than one job beginning with the string typed, the job most recently +accessed is selected. The +.I name +of a stopped job, in this context, is the command line used to +start it. +If set to the value +.IR exact , +the string supplied must match the name of a stopped job exactly; +if set to +.IR substring , +the string supplied needs to match a substring of the name of a +stopped job. The +.I substring +value provides functionality analogous to the +.B %? +job identifier (see +.SM +.B JOB CONTROL +below). If set to any other value, the supplied string must +be a prefix of a stopped job's name; this provides functionality +analogous to the +.B % +job identifier. +.TP +.B histchars +The two or three characters which control history expansion +and tokenization (see +.SM +.B HISTORY EXPANSION +below). The first character is the \fIhistory expansion\fP character, +the character which signals the start of a history +expansion, normally `\fB!\fP'. +The second character is the \fIquick substitution\fP +character, which is used as shorthand for re-running the previous +command entered, substituting one string for another in the command. +The default is `\fB^\fP'. +The optional third character is the character +which indicates that the remainder of the line is a comment when found +as the first character of a word, normally `\fB#\fP'. The history +comment character causes history substitution to be skipped for the +remaining words on the line. It does not necessarily cause the shell +parser to treat the rest of the line as a comment. +.PD +.SS Arrays +.B Bash +provides one-dimensional array variables. Any variable may be used as +an array; the +.B declare +builtin will explicitly declare an array. There is no maximum +limit on the size of an array, nor any requirement that members +be indexed or assigned contiguously. Arrays are indexed using +integers and are zero-based. +.PP +An array is created automatically if any variable is assigned to using +the syntax \fIname\fP[\fIsubscript\fP]=\fIvalue\fP. The +.I subscript +is treated as an arithmetic expression that must evaluate to a number +greater than or equal to zero. To explicitly declare an array, use +.B declare \-a \fIname\fP +(see +.SM +.B SHELL BUILTIN COMMANDS +below). +.B declare \-a \fIname\fP[\fIsubscript\fP] +is also accepted; the \fIsubscript\fP is ignored. Attributes may be +specified for an array variable using the +.B declare +and +.B readonly +builtins. Each attribute applies to all members of an array. +.PP +Arrays are assigned to using compound assignments of the form +\fIname\fP=\fB(\fPvalue\fI1\fP ... value\fIn\fP\fB)\fP, where each +\fIvalue\fP is of the form [\fIsubscript\fP]=\fIstring\fP. Only +\fIstring\fP is required. If +the optional brackets and subscript are supplied, that index is assigned to; +otherwise the index of the element assigned is the last index assigned +to by the statement plus one. Indexing starts at zero. +This syntax is also accepted by the +.B declare +builtin. Individual array elements may be assigned to using the +\fIname\fP[\fIsubscript\fP]=\fIvalue\fP syntax introduced above. +.PP +Any element of an array may be referenced using +${\fIname\fP[\fIsubscript\fP]}. The braces are required to avoid +conflicts with pathname expansion. If +\fIsubscript\fP is \fB@\fP or \fB*\fP, the word expands to +all members of \fIname\fP. These subscripts differ only when the +word appears within double quotes. If the word is double-quoted, +${\fIname\fP[*]} expands to a single +word with the value of each array member separated by the first +character of the +.SM +.B IFS +special variable, and ${\fIname\fP[@]} expands each element of +\fIname\fP to a separate word. When there are no array members, +${\fIname\fP[@]} expands to nothing. This is analogous to the expansion +of the special parameters \fB*\fP and \fB@\fP (see +.B Special Parameters +above). ${#\fIname\fP[\fIsubscript\fP]} expands to the length of +${\fIname\fP[\fIsubscript\fP]}. If \fIsubscript\fP is \fB*\fP or +\fB@\fP, the expansion is the number of elements in the array. +Referencing an array variable without a subscript is equivalent to +referencing element zero. +.PP +The +.B unset +builtin is used to destroy arrays. \fBunset\fP \fIname\fP[\fIsubscript\fP] +destroys the array element at index \fIsubscript\fP. +\fBunset\fP \fIname\fP, where \fIname\fP is an array, or +\fBunset\fP \fIname\fP[\fIsubscript\fP], where +\fIsubscript\fP is \fB*\fP or \fB@\fP, removes the entire array. +.PP +The +.BR declare , +.BR local , +and +.B readonly +builtins each accept a +.B \-a +option to specify an array. The +.B read +builtin accepts a +.B \-a +option to assign a list of words read from the standard input +to an array. The +.B set +and +.B declare +builtins display array values in a way that allows them to be +reused as assignments. +.SH EXPANSION +Expansion is performed on the command line after it has been split into +words. There are seven kinds of expansion performed: +.IR "brace expansion" , +.IR "tilde expansion" , +.IR "parameter and variable expansion" , +.IR "command substitution" , +.IR "arithmetic expansion" , +.IR "word splitting" , +and +.IR "pathname expansion" . +.PP +The order of expansions is: brace expansion, tilde expansion, +parameter, variable and arithmetic expansion and +command substitution +(done in a left-to-right fashion), word splitting, and pathname +expansion. +.PP +On systems that can support it, there is an additional expansion +available: \fIprocess substitution\fP. +.PP +Only brace expansion, word splitting, and pathname expansion +can change the number of words of the expansion; other expansions +expand a single word to a single word. +The only exceptions to this are the expansions of +"\fB$@\fP" and "\fB${\fP\fIname\fP\fB[@]}\fP" +as explained above (see +.SM +.BR PARAMETERS ). +.SS Brace Expansion +.PP +.I "Brace expansion" +is a mechanism by which arbitrary strings +may be generated. This mechanism is similar to +\fIpathname expansion\fP, but the filenames generated +need not exist. Patterns to be brace expanded take +the form of an optional +.IR preamble , +followed by either a series of comma-separated strings or +a sequence expression between a pair of braces, followed by +an optional +.IR postscript . +The preamble is prefixed to each string contained +within the braces, and the postscript is then appended +to each resulting string, expanding left to right. +.PP +Brace expansions may be nested. The results of each expanded +string are not sorted; left to right order is preserved. +For example, a\fB{\fPd,c,b\fB}\fPe expands into `ade ace abe'. +.PP +A sequence expression takes the form \fB{\fP\fIx\fP\fB..\fP\fIy\fP\fB}\fP, +where \fIx\fP and \fIy\fP are either integers or single characters. +When integers are supplied, the expression expands to each number between +\fIx\fP and \fIy\fP, inclusive. +When characters are supplied, the expression expands to each character +lexicographically between \fIx\fP and \fIy\fP, inclusive. Note that +both \fIx\fP and \fIy\fP must be of the same type. +.PP +Brace expansion is performed before any other expansions, +and any characters special to other expansions are preserved +in the result. It is strictly textual. +.B Bash +does not apply any syntactic interpretation to the context of the +expansion or the text between the braces. +.PP +A correctly-formed brace expansion must contain unquoted opening +and closing braces, and at least one unquoted comma or a valid +sequence expression. +Any incorrectly formed brace expansion is left unchanged. +A \fB{\fP or \fB,\fP may be quoted with a backslash to prevent its +being considered part of a brace expression. +To avoid conflicts with parameter expansion, the string \fB${\fP +is not considered eligible for brace expansion. +.PP +This construct is typically used as shorthand when the common +prefix of the strings to be generated is longer than in the +above example: +.RS +.PP +mkdir /usr/local/src/bash/{old,new,dist,bugs} +.RE +or +.RS +chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}} +.RE +.PP +Brace expansion introduces a slight incompatibility with +historical versions of +.BR sh . +.B sh +does not treat opening or closing braces specially when they +appear as part of a word, and preserves them in the output. +.B Bash +removes braces from words as a consequence of brace +expansion. For example, a word entered to +.B sh +as \fIfile{1,2}\fP +appears identically in the output. The same word is +output as +.I file1 file2 +after expansion by +.BR bash . +If strict compatibility with +.B sh +is desired, start +.B bash +with the +.B +B +option or disable brace expansion with the +.B +B +option to the +.B set +command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.SS Tilde Expansion +.PP +If a word begins with an unquoted tilde character (`\fB~\fP'), all of +the characters preceding the first unquoted slash (or all characters, +if there is no unquoted slash) are considered a \fItilde-prefix\fP. +If none of the characters in the tilde-prefix are quoted, the +characters in the tilde-prefix following the tilde are treated as a +possible \fIlogin name\fP. +If this login name is the null string, the tilde is replaced with the +value of the shell parameter +.SM +.BR HOME . +If +.SM +.B HOME +is unset, the home directory of the user executing the shell is +substituted instead. +Otherwise, the tilde-prefix is replaced with the home directory +associated with the specified login name. +.PP +If the tilde-prefix is a `~+', the value of the shell variable +.SM +.B PWD +replaces the tilde-prefix. +If the tilde-prefix is a `~\-', the value of the shell variable +.SM +.BR OLDPWD , +if it is set, is substituted. +If the characters following the tilde in the tilde-prefix consist +of a number \fIN\fP, optionally prefixed +by a `+' or a `\-', the tilde-prefix is replaced with the corresponding +element from the directory stack, as it would be displayed by the +.B dirs +builtin invoked with the tilde-prefix as an argument. +If the characters following the tilde in the tilde-prefix consist of a +number without a leading `+' or `\-', `+' is assumed. +.PP +If the login name is invalid, or the tilde expansion fails, the word +is unchanged. +.PP +Each variable assignment is checked for unquoted tilde-prefixes immediately +following a +.B : +or +.BR = . +In these cases, tilde expansion is also performed. +Consequently, one may use file names with tildes in assignments to +.SM +.BR PATH , +.SM +.BR MAILPATH , +and +.SM +.BR CDPATH , +and the shell assigns the expanded value. +.SS Parameter Expansion +.PP +The `\fB$\fP' character introduces parameter expansion, +command substitution, or arithmetic expansion. The parameter name +or symbol to be expanded may be enclosed in braces, which +are optional but serve to protect the variable to be expanded from +characters immediately following it which could be +interpreted as part of the name. +.PP +When braces are used, the matching ending brace is the first `\fB}\fP' +not escaped by a backslash or within a quoted string, and not within an +embedded arithmetic expansion, command substitution, or paramter +expansion. +.PP +.PD 0 +.TP +${\fIparameter\fP} +The value of \fIparameter\fP is substituted. The braces are required +when +.I parameter +is a positional parameter with more than one digit, +or when +.I parameter +is followed by a character which is not to be +interpreted as part of its name. +.PD +.PP +If the first character of \fIparameter\fP is an exclamation point, +a level of variable indirection is introduced. +\fBBash\fP uses the value of the variable formed from the rest of +\fIparameter\fP as the name of the variable; this variable is then +expanded and that value is used in the rest of the substitution, rather +than the value of \fIparameter\fP itself. +This is known as \fIindirect expansion\fP. +The exceptions to this are the expansions of ${!\fIprefix\fP*} and +${\fB!\fP\fIname\fP[\fI@\fP]} described below. +The exclamation point must immediately follow the left brace in order to +introduce indirection. +.PP +In each of the cases below, \fIword\fP is subject to tilde expansion, +parameter expansion, command substitution, and arithmetic expansion. +When not performing substring expansion, \fBbash\fP tests for a parameter +that is unset or null; omitting the colon results in a test only for a +parameter that is unset. +.PP +.PD 0 +.TP +${\fIparameter\fP\fB:\-\fP\fIword\fP} +\fBUse Default Values\fP. If +.I parameter +is unset or null, the expansion of +.I word +is substituted. Otherwise, the value of +.I parameter +is substituted. +.TP +${\fIparameter\fP\fB:=\fP\fIword\fP} +\fBAssign Default Values\fP. +If +.I parameter +is unset or null, the expansion of +.I word +is assigned to +.IR parameter . +The value of +.I parameter +is then substituted. Positional parameters and special parameters may +not be assigned to in this way. +.TP +${\fIparameter\fP\fB:?\fP\fIword\fP} +\fBDisplay Error if Null or Unset\fP. +If +.I parameter +is null or unset, the expansion of \fIword\fP (or a message to that effect +if +.I word +is not present) is written to the standard error and the shell, if it +is not interactive, exits. Otherwise, the value of \fIparameter\fP is +substituted. +.TP +${\fIparameter\fP\fB:+\fP\fIword\fP} +\fBUse Alternate Value\fP. +If +.I parameter +is null or unset, nothing is substituted, otherwise the expansion of +.I word +is substituted. +.TP +${\fIparameter\fP\fB:\fP\fIoffset\fP} +.PD 0 +.TP +${\fIparameter\fP\fB:\fP\fIoffset\fP\fB:\fP\fIlength\fP} +.PD +\fBSubstring Expansion.\fP +Expands to up to \fIlength\fP characters of \fIparameter\fP +starting at the character specified by \fIoffset\fP. +If \fIlength\fP is omitted, expands to the substring of +\fIparameter\fP starting at the character specified by \fIoffset\fP. +\fIlength\fP and \fIoffset\fP are arithmetic expressions (see +.SM +.B +ARITHMETIC EVALUATION +below). +\fIlength\fP must evaluate to a number greater than or equal to zero. +If \fIoffset\fP evaluates to a number less than zero, the value +is used as an offset from the end of the value of \fIparameter\fP. +If \fIparameter\fP is \fB@\fP, the result is \fIlength\fP positional +parameters beginning at \fIoffset\fP. +If \fIparameter\fP is an array name indexed by @ or *, +the result is the \fIlength\fP +members of the array beginning with ${\fIparameter\fP[\fIoffset\fP]}. +Substring indexing is zero-based unless the positional parameters +are used, in which case the indexing starts at 1. +.TP +${\fB!\fP\fIprefix\fP\fB*\fP} +.PD 0 +.TP +${\fB!\fP\fIprefix\fP\fB@\fP} +.PD +Expands to the names of variables whose names begin with \fIprefix\fP, +separated by the first character of the +.SM +.B IFS +special variable. +.TP +${\fB!\fP\fIname\fP[\fI@\fP]} +.PD 0 +.TP +${\fB!\fP\fIname\fP[\fI*\fP]} +.PD +If \fIname\fP is an array variable, expands to the list of array indices +(keys) assigned in \fIname\fP. +If \fIname\fP is not an array, expands to 0 if \fIname\fP is set and null +otherwise. +When \fI@\fP is used and the expansion appears within double quotes, each +key expands to a separate word. +.TP +${\fB#\fP\fIparameter\fP} +The length in characters of the value of \fIparameter\fP is substituted. +If +.I parameter +is +.B * +or +.BR @ , +the value substituted is the number of positional parameters. +If +.I parameter +is an array name subscripted by +.B * +or +.BR @ , +the value substituted is the number of elements in the array. +.TP +${\fIparameter\fP\fB#\fP\fIword\fP} +.PD 0 +.TP +${\fIparameter\fP\fB##\fP\fIword\fP} +.PD +The +.I word +is expanded to produce a pattern just as in pathname +expansion.

There are two forms: +.PP +.RS +.PP +\fB$(\fP\fIcommand\fP\|\fB)\fP +.RE +or +.RS +\fB`\fP\fIcommand\fP\fB`\fP +.RE +.PP +.B Bash +performs the expansion by executing \fIcommand\fP and +replacing the command substitution with the standard output of the +command, with any trailing newlines deleted. +Embedded newlines are not deleted, but they may be removed during +word splitting. +The command substitution \fB$(cat \fIfile\fP)\fR can be replaced by +the equivalent but faster \fB$(< \fIfile\fP)\fR. +.PP +When the old-style backquote form of substitution is used, +backslash retains its literal meaning except when followed by +.BR $ , +.BR ` , +or +.BR \e . +The first backquote not preceded by a backslash terminates the +command substitution. +When using the $(\^\fIcommand\fP\|) form, all characters between the +parentheses make up the command; none are treated specially. +.PP +Command substitutions may be nested. To nest when using the backquoted form, +escape the inner backquotes with backslashes. +.PP +If the substitution appears within double quotes, word splitting and +pathname expansion are not performed on the results. +.SS Arithmetic Expansion +.PP +Arithmetic expansion allows the evaluation of an arithmetic expression +and the substitution of the result. The format for arithmetic expansion is: +.RS +.PP +\fB$((\fP\fIexpression\fP\fB))\fP +.RE +.PP +The +.I expression +is treated as if it were within double quotes, but a double quote +inside the parentheses is not treated specially. +All tokens in the expression undergo parameter expansion, string +expansion, command substitution, and quote removal. +Arithmetic expansions may be nested. +.PP +The evaluation is performed according to the rules listed below under +.SM +.BR "ARITHMETIC EVALUATION" . +If +.I expression +is invalid, +.B bash +prints a message indicating failure and no substitution occurs. +.SS Process Substitution +.PP +\fIProcess substitution\fP is supported on systems that support named +pipes (\fIFIFOs\fP) or the \fB/dev/fd\fP method of naming open files. +It takes the form of +\fB<(\fP\fIlist\^\fP\fB)\fP +or +\fB>(\fP\fIlist\^\fP\fB)\fP. +The process \fIlist\fP is run with its input or output connected to a +\fIFIFO\fP or some file in \fB/dev/fd\fP. The name of this file is +passed as an argument to the current command as the result of the +expansion. If the \fB>(\fP\fIlist\^\fP\fB)\fP form is used, writing to +the file will provide input for \fIlist\fP. If the +\fB<(\fP\fIlist\^\fP\fB)\fP form is used, the file passed as an +argument should be read to obtain the output of \fIlist\fP. +.PP +When available, process substitution is performed +simultaneously with parameter and variable expansion, +command substitution, +and arithmetic expansion. +.SS Word Splitting +.PP +The shell scans the results of +parameter expansion, +command substitution, +and +arithmetic expansion +that did not occur within double quotes for +.IR "word splitting" . +.PP +The shell treats each character of +.SM +.B IFS +as a delimiter, and splits the results of the other +expansions into words on these characters. If +.SM +.B IFS +is unset, or its +value is exactly +.BR , +the default, then +any sequence of +.SM +.B IFS +characters serves to delimit words. If +.SM +.B IFS +has a value other than the default, then sequences of +the whitespace characters +.B space +and +.B tab +are ignored at the beginning and end of the +word, as long as the whitespace character is in the +value of +.SM +.BR IFS +(an +.SM +.B IFS +whitespace character). +Any character in +.SM +.B IFS +that is not +.SM +.B IFS +whitespace, along with any adjacent +.SM +.B IFS +whitespace characters, delimits a field. +A sequence of +.SM +.B IFS +whitespace characters is also treated as a delimiter. +If the value of +.SM +.B IFS +is null, no word splitting occurs. +.PP +Explicit null arguments (\^\f3"\^"\fP or \^\f3'\^'\fP\^) are retained. +Unquoted implicit null arguments, resulting from the expansion of +parameters that have no values, are removed. +If a parameter with no value is expanded within double quotes, a +null argument results and is retained. +.PP +Note that if no expansion occurs, no splitting +is performed. +.SS Pathname Expansion +.PP +After word splitting, +unless the +.B \-f +option has been set, +.B bash +scans each word for the characters +.BR * , +.BR ? , +and +.BR [ . +If one of these characters appears, then the word is +regarded as a +.IR pattern , +and replaced with an alphabetically sorted list of +file names matching the pattern. +If no matching file names are found, +and the shell option +.B nullglob +is disabled, the word is left unchanged. +If the +.B nullglob +option is set, and no matches are found, +the word is removed. +If the shell option +.B nocaseglob +is enabled, the match is performed without regard to the case +of alphabetic characters. +When a pattern is used for pathname expansion, +the character +.B ``.'' +at the start of a name or immediately following a slash +must be matched explicitly, unless the shell option +.B dotglob +is set. +When matching a pathname, the slash character must always be +matched explicitly. +In other cases, the +.B ``.'' +character is not treated specially. +See the description of +.B shopt +below under +.SM +.B SHELL BUILTIN COMMANDS +for a description of the +.BR nocaseglob , +.BR nullglob , +and +.B dotglob +shell options. +.PP +The +.SM +.B GLOBIGNORE +shell variable may be used to restrict the set of file names matching a +.IR pattern . +If +.SM +.B GLOBIGNORE +is set, each matching file name that also matches one of the patterns in +.SM +.B GLOBIGNORE +is removed from the list of matches. +The file names +.B ``.'' +and +.B ``..'' +are always ignored when +.SM +.B GLOBIGNORE +is set and not null. However, setting +.SM +.B GLOBIGNORE +to a non-null value has the effect of enabling the +.B dotglob +shell option, so all other file names beginning with a +.B ``.'' +will match. +To get the old behavior of ignoring file names beginning with a +.BR ``.'' , +make +.B ``.*'' +one of the patterns in +.SM +.BR GLOBIGNORE . +The +.B dotglob +option is disabled when +.SM +.B GLOBIGNORE +is unset. +.PP +\fBPattern Matching\fP +.PP +Any character that appears in a pattern, other than the special pattern +characters described below, matches itself.

If +.I n +is not specified, the standard input (file descriptor 0) is used. +.PP +The operator +.RS +.PP +[\fIn\fP]\fB>&\fP\fIword\fP +.RE +.PP +is used similarly to duplicate output file descriptors. If +.I n +is not specified, the standard output (file descriptor 1) is used. +If the digits in +.I word +do not specify a file descriptor open for output, a redirection error occurs. +As a special case, if \fIn\fP is omitted, and \fIword\fP does not +expand to one or more digits, the standard output and standard +error are redirected as described previously. +.SS "Moving File Descriptors" +.PP +The redirection operator +.RS +.PP +[\fIn\fP]\fB<&\fP\fIdigit\fP\fB\-\fP +.RE +.PP +moves the file descriptor \fIdigit\fP to file descriptor +.IR n , +or the standard input (file descriptor 0) if \fIn\fP is not specified. +\fIdigit\fP is closed after being duplicated to \fIn\fP. +.PP +Similarly, the redirection operator +.RS +.PP +[\fIn\fP]\fB>&\fP\fIdigit\fP\fB\-\fP +.RE +.PP +moves the file descriptor \fIdigit\fP to file descriptor +.IR n , +or the standard output (file descriptor 1) if \fIn\fP is not specified. +.SS "Opening File Descriptors for Reading and Writing" +.PP +The redirection operator +.RS +.PP +[\fIn\fP]\fB<>\fP\fIword\fP +.RE +.PP +causes the file whose name is the expansion of +.I word +to be opened for both reading and writing on file descriptor +.IR n , +or on file descriptor 0 if +.I n +is not specified. If the file does not exist, it is created. +.SH ALIASES +\fIAliases\fP allow a string to be substituted for a word when it is used +as the first word of a simple command. +The shell maintains a list of aliases that may be set and unset with the +.B alias +and +.B unalias +builtin commands (see +.SM +.B SHELL BUILTIN COMMANDS +below). +The first word of each command, if unquoted, +is checked to see if it has an +alias. If so, that word is replaced by the text of the alias. +The alias name and the replacement text may contain any valid +shell input, including the +.I metacharacters +listed above, with the exception that the alias name may not +contain \fI=\fP. The first word of the replacement text is tested +for aliases, but a word that is identical to an alias being expanded +is not expanded a second time. This means that one may alias +.B ls +to +.BR "ls \-F" , +for instance, and +.B bash +does not try to recursively expand the replacement text. +If the last character of the alias value is a +.IR blank , +then the next command +word following the alias is also checked for alias expansion. +.PP +Aliases are created and listed with the +.B alias +command, and removed with the +.B unalias +command. +.PP +There is no mechanism for using arguments in the replacement text. +If arguments are needed, a shell function should be used (see +.SM +.B FUNCTIONS +below). +.PP +Aliases are not expanded when the shell is not interactive, unless +the +.B expand_aliases +shell option is set using +.B shopt +(see the description of +.B shopt +under +.SM +\fBSHELL BUILTIN COMMANDS\fP +below). +.PP +The rules concerning the definition and use of aliases are +somewhat confusing. +.B Bash +always reads at least one complete line +of input before executing any +of the commands on that line. Aliases are expanded when a +command is read, not when it is executed. Therefore, an +alias definition appearing on the same line as another +command does not take effect until the next line of input is read. +The commands following the alias definition +on that line are not affected by the new alias. +This behavior is also an issue when functions are executed. +Aliases are expanded when a function definition is read, +not when the function is executed, because a function definition +is itself a compound command. As a consequence, aliases +defined in a function are not available until after that +function is executed. To be safe, always put +alias definitions on a separate line, and do not use +.B alias +in compound commands. +.PP +For almost every purpose, aliases are superseded by +shell functions. +.SH FUNCTIONS +A shell function, defined as described above under +.SM +.BR "SHELL GRAMMAR" , +stores a series of commands for later execution. +When the name of a shell function is used as a simple command name, +the list of commands associated with that function name is executed. +Functions are executed in the context of the +current shell; no new process is created to interpret +them (contrast this with the execution of a shell script). +When a function is executed, the arguments to the +function become the positional parameters +during its execution. +The special parameter +.B # +is updated to reflect the change. Positional parameter 0 +is unchanged. +The first element of the +.SM +.B FUNCNAME +variable is set to the name of the function while the function +is executing. +All other aspects of the shell execution +environment are identical between a function and its caller +with the exception that the +.SM +.B DEBUG +trap (see the description of the +.B trap +builtin under +.SM +.B SHELL BUILTIN COMMANDS +below) is not inherited unless the function has been given the +\fBtrace\fP attribute (see the description of the +.SM +.B declare +builtin below) or the +\fB\-o functrace\fP shell option has been enabled with +the \fBset\fP builtin +(in which case all functions inherit the \fBDEBUG\fP trap). +.PP +Variables local to the function may be declared with the +.B local +builtin command. Ordinarily, variables and their values +are shared between the function and its caller. +.PP +If the builtin command +.B return +is executed in a function, the function completes and +execution resumes with the next command after the function +call. +Any command associated with the \fBRETURN\fP trap is executed +before execution resumes. +When a function completes, the values of the +positional parameters and the special parameter +.B # +are restored to the values they had prior to the function's +execution. +.PP +Function names and definitions may be listed with the +.B \-f +option to the +.B declare +or +.B typeset +builtin commands. The +.B \-F +option to +.B declare +or +.B typeset +will list the function names only +(and optionally the source file and line number, if the \fBextdebug\fP +shell option is enabled). +Functions may be exported so that subshells +automatically have them defined with the +.B \-f +option to the +.B export +builtin. +Note that shell functions and variables with the same name may result +in multiple identically-named entries in the environment passed to the +shell's children. +Care should be taken in cases where this may cause a problem. +.PP +Functions may be recursive. No limit is imposed on the number +of recursive calls. +.SH "ARITHMETIC EVALUATION" +The shell allows arithmetic expressions to be evaluated, under +certain circumstances (see the \fBlet\fP and \fBdeclare\fP builtin +commands and \fBArithmetic Expansion\fP). +Evaluation is done in fixed-width integers with no check for overflow, +though division by 0 is trapped and flagged as an error. +The operators and their precedence, associativity, and values +are the same as in the C language. +The following list of operators is grouped into levels of +equal-precedence operators. +The levels are listed in order of decreasing precedence. +.PP +.PD 0 +.TP +.B \fIid\fP++ \fIid\fP\-\- +variable post-increment and post-decrement +.TP +.B ++\fIid\fP \-\-\fIid\fP +variable pre-increment and pre-decrement +.TP +.B \- + +unary minus and plus +.TP +.B ! ~ +logical and bitwise negation +.TP +.B ** +exponentiation +.TP +.B * / % +multiplication, division, remainder +.TP +.B + \- +addition, subtraction +.TP +.B << >> +left and right bitwise shifts +.TP +.B <= >= < > +comparison +.TP +.B == != +equality and inequality +.TP +.B & +bitwise AND +.TP +.B ^ +bitwise exclusive OR +.TP +.B | +bitwise OR +.TP +.B && +logical AND +.TP +.B || +logical OR +.TP +.B \fIexpr\fP?\fIexpr\fP:\fIexpr\fP +conditional operator +.TP +.B = *= /= %= += \-= <<= >>= &= ^= |= +assignment +.TP +.B \fIexpr1\fP , \fIexpr2\fP +comma +.PD +.PP +Shell variables are allowed as operands; parameter expansion is +performed before the expression is evaluated. +Within an expression, shell variables may also be referenced by name +without using the parameter expansion syntax. +A shell variable that is null or unset evaluates to 0 when referenced +by name without using the parameter expansion syntax. +The value of a variable is evaluated as an arithmetic expression +when it is referenced, or when a variable which has been given the +\fIinteger\fP attribute using \fBdeclare -i\fP is assigned a value. +A null value evaluates to 0. +A shell variable need not have its integer attribute +turned on to be used in an expression. +.PP +Constants with a leading 0 are interpreted as octal numbers. +A leading 0x or 0X denotes hexadecimal. +Otherwise, numbers take the form [\fIbase#\fP]n, where \fIbase\fP +is a decimal number between 2 and 64 representing the arithmetic +base, and \fIn\fP is a number in that base. +If \fIbase#\fP is omitted, then base 10 is used. +The digits greater than 9 are represented by the lowercase letters, +the uppercase letters, @, and _, in that order. +If \fIbase\fP is less than or equal to 36, lowercase and uppercase +letters may be used interchangably to represent numbers between 10 +and 35. +.PP +Operators are evaluated in order of precedence.

Otherwise, the variables are added to the environment +of the executed command and do not affect the current shell environment. +If any of the assignments attempts to assign a value to a readonly variable, +an error occurs, and the command exits with a non-zero status. +.PP +If no command name results, redirections are performed, but do not +affect the current shell environment. A redirection error causes the +command to exit with a non-zero status. +.PP +If there is a command name left after expansion, execution proceeds as +described below. Otherwise, the command exits. If one of the expansions +contained a command substitution, the exit status of the command is +the exit status of the last command substitution performed.

If there exists a shell function by that name, that +function is invoked as described above in +.SM +.BR FUNCTIONS . +If the name does not match a function, the shell searches for +it in the list of shell builtins. If a match is found, that +builtin is invoked. +.PP +If the name is neither a shell function nor a builtin, +and contains no slashes, +.B bash +searches each element of the +.SM +.B PATH +for a directory containing an executable file by that name. +.B Bash +uses a hash table to remember the full pathnames of executable +files (see +.B hash +under +.SM +.B "SHELL BUILTIN COMMANDS" +below). +A full search of the directories in +.SM +.B PATH +is performed only if the command is not found in the hash table. +If the search is unsuccessful, the shell prints an error +message and returns an exit status of 127. +.PP +If the search is successful, or if the command name contains +one or more slashes, the shell executes the named program in a +separate execution environment. +Argument 0 is set to the name given, and the remaining arguments +to the command are set to the arguments given, if any. +.PP +If this execution fails because the file is not in executable +format, and the file is not a directory, it is assumed to be +a \fIshell script\fP, a file +containing shell commands. A subshell is spawned to execute +it. This subshell reinitializes itself, so +that the effect is as if a new shell had been invoked +to handle the script, with the exception that the locations of +commands remembered by the parent (see +.B hash +below under +.SM +\fBSHELL BUILTIN COMMANDS\fP) +are retained by the child. +.PP +If the program is a file beginning with +.BR #! , +the remainder of the first line specifies an interpreter +for the program. The shell executes the +specified interpreter on operating systems that do not +handle this executable format themselves. The arguments to the +interpreter consist of a single optional argument following the +interpreter name on the first line of the program, followed +by the name of the program, followed by the command +arguments, if any. +.SH COMMAND EXECUTION ENVIRONMENT +The shell has an \fIexecution environment\fP, which consists of the +following: +.sp 1 +.IP \(bu +open files inherited by the shell at invocation, as modified by +redirections supplied to the \fBexec\fP builtin +.IP \(bu +the current working directory as set by \fBcd\fP, \fBpushd\fP, or +\fBpopd\fP, or inherited by the shell at invocation +.IP \(bu +the file creation mode mask as set by \fBumask\fP or inherited from +the shell's parent +.IP \(bu +current traps set by \fBtrap\fP +.IP \(bu +shell parameters that are set by variable assignment or with \fBset\fP +or inherited from the shell's parent in the environment +.IP \(bu +shell functions defined during execution or inherited from the shell's +parent in the environment +.IP \(bu +options enabled at invocation (either by default or with command-line +arguments) or by \fBset\fP +.IP \(bu +options enabled by \fBshopt\fP +.IP \(bu +shell aliases defined with \fBalias\fP +.IP \(bu +various process IDs, including those of background jobs, the value +of \fB$$\fP, and the value of \fB$PPID\fP +.PP +When a simple command other than a builtin or shell function +is to be executed, it +is invoked in a separate execution environment that consists of +the following. Unless otherwise noted, the values are inherited +from the shell. +.sp 1 +.IP \(bu +the shell's open files, plus any modifications and additions specified +by redirections to the command +.IP \(bu +the current working directory +.IP \(bu +the file creation mode mask +.IP \(bu +shell variables and functions marked for export, along with variables +exported for the command, passed in the environment +.IP \(bu +traps caught by the shell are reset to the values the inherited +from the shell's parent, and traps ignored by the shell are ignored +.PP +A command invoked in this separate environment cannot affect the +shell's execution environment. +.PP +Command substitution and asynchronous commands are invoked in a +subshell environment that is a duplicate of the shell environment, +except that traps caught by the shell are reset to the values +that the shell inherited from its parent at invocation. Builtin +commands that are invoked as part of a pipeline are also executed in a +subshell environment. Changes made to the subshell environment +cannot affect the shell's execution environment. +.PP +If a command is followed by a \fB&\fP and job control is not active, the +default standard input for the command is the empty file \fI/dev/null\fP. +Otherwise, the invoked command inherits the file descriptors of the calling +shell as modified by redirections. +.SH ENVIRONMENT +When a program is invoked it is given an array of strings +called the +.IR environment . +This is a list of +\fIname\fP\-\fIvalue\fP pairs, of the form +.IR "name\fR=\fPvalue" . +.PP +The shell provides several ways to manipulate the environment. +On invocation, the shell scans its own environment and +creates a parameter for each name found, automatically marking +it for +.I export +to child processes. Executed commands inherit the environment. +The +.B export +and +.B declare \-x +commands allow parameters and functions to be added to and +deleted from the environment. If the value of a parameter +in the environment is modified, the new value becomes part +of the environment, replacing the old. The environment +inherited by any executed command consists of the shell's +initial environment, whose values may be modified in the shell, +less any pairs removed by the +.B unset +command, plus any additions via the +.B export +and +.B declare \-x +commands. +.PP +The environment for any +.I simple command +or function may be augmented temporarily by prefixing it with +parameter assignments, as described above in +.SM +.BR PARAMETERS . +These assignment statements affect only the environment seen +by that command. +.PP +If the +.B \-k +option is set (see the +.B set +builtin command below), then +.I all +parameter assignments are placed in the environment for a command, +not just those that precede the command name. +.PP +When +.B bash +invokes an external command, the variable +.B _ +is set to the full file name of the command and passed to that +command in its environment. +.SH "EXIT STATUS" +For the shell's purposes, a command which exits with a +zero exit status has succeeded. An exit status of zero +indicates success. A non-zero exit status indicates failure. +When a command terminates on a fatal signal \fIN\fP, \fBbash\fP uses +the value of 128+\fIN\fP as the exit status. +.PP +If a command is not found, the child process created to +execute it returns a status of 127. If a command is found +but is not executable, the return status is 126. +.PP +If a command fails because of an error during expansion or redirection, +the exit status is greater than zero. +.PP +Shell builtin commands return a status of 0 (\fItrue\fP) if +successful, and non-zero (\fIfalse\fP) if an error occurs +while they execute. +All builtins return an exit status of 2 to indicate incorrect usage. +.PP +\fBBash\fP itself returns the exit status of the last command +executed, unless a syntax error occurs, in which case it exits +with a non-zero value. See also the \fBexit\fP builtin +command below. +.SH SIGNALS +When \fBbash\fP is interactive, in the absence of any traps, it ignores +.SM +.B SIGTERM +(so that \fBkill 0\fP does not kill an interactive shell), +and +.SM +.B SIGINT +is caught and handled (so that the \fBwait\fP builtin is interruptible). +In all cases, \fBbash\fP ignores +.SM +.BR SIGQUIT . +If job control is in effect, +.B bash +ignores +.SM +.BR SIGTTIN , +.SM +.BR SIGTTOU , +and +.SM +.BR SIGTSTP . +.PP +Synchronous jobs started by \fBbash\fP have signal handlers +set to the values inherited by the shell from its parent. +When job control is not in effect, asynchronous commands +ignore +.SM +.B SIGINT +and +.SM +.B SIGQUIT +as well. +Commands run as a result of command substitution ignore the +keyboard-generated job control signals +.SM +.BR SIGTTIN , +.SM +.BR SIGTTOU , +and +.SM +.BR SIGTSTP . +.PP +The shell exits by default upon receipt of a +.SM +.BR SIGHUP . +Before exiting, an interactive shell resends the +.SM +.B SIGHUP +to all jobs, running or stopped. +Stopped jobs are sent +.SM +.B SIGCONT +to ensure that they receive the +.SM +.BR SIGHUP . +To prevent the shell from +sending the signal to a particular job, it should be removed from the +jobs table with the +.B disown +builtin (see +.SM +.B "SHELL BUILTIN COMMANDS" +below) or marked +to not receive +.SM +.B SIGHUP +using +.BR "disown \-h" . +.PP +If the +.B huponexit +shell option has been set with +.BR shopt , +.B bash +sends a +.SM +.B SIGHUP +to all jobs when an interactive login shell exits. +.PP +When \fBbash\fP receives a signal for which a trap has been set while +waiting for a command to complete, the trap will not be executed until +the command completes. +When \fBbash\fP is waiting for an asynchronous command via the \fBwait\fP +builtin, the reception of a signal for which a trap has been set will +cause the \fBwait\fP builtin to return immediately with an exit status +greater than 128, immediately after which the trap is executed. +.SH "JOB CONTROL" +.I Job control +refers to the ability to selectively stop (\fIsuspend\fP) +the execution of processes and continue (\fIresume\fP) +their execution at a later point. A user typically employs +this facility via an interactive interface supplied jointly +by the system's terminal driver and +.BR bash . +.PP +The shell associates a +.I job +with each pipeline. It keeps a table of currently executing +jobs, which may be listed with the +.B jobs +command. When +.B bash +starts a job asynchronously (in the +.IR background ), +it prints a line that looks like: +.RS +.PP +[1] 25647 +.RE +.PP +indicating that this job is job number 1 and that the process ID +of the last process in the pipeline associated with this job is 25647. +All of the processes in a single pipeline are members of the same job. +.B Bash +uses the +.I job +abstraction as the basis for job control. +.PP +To facilitate the implementation of the user interface to job +control, the operating system maintains the notion of a \fIcurrent terminal +process group ID\fP. Members of this process group (processes whose +process group ID is equal to the current terminal process group ID) +receive keyboard-generated signals such as +.SM +.BR SIGINT . +These processes are said to be in the +.IR foreground . +.I Background +processes are those whose process group ID differs from the terminal's; +such processes are immune to keyboard-generated signals. +Only foreground processes are allowed to read from or write to the +terminal. Background processes which attempt to read from (write to) the +terminal are sent a +.SM +.B SIGTTIN (SIGTTOU) +signal by the terminal driver, +which, unless caught, suspends the process. +.PP +If the operating system on which +.B bash +is running supports +job control, +.B bash +contains facilities to use it. +Typing the +.I suspend +character (typically +.BR ^Z , +Control-Z) while a process is running +causes that process to be stopped and returns control to +.BR bash . +Typing the +.I "delayed suspend" +character (typically +.BR ^Y , +Control-Y) causes the process to be stopped when it +attempts to read input from the terminal, and control to +be returned to +.BR bash . +The user may then manipulate the state of this job, using the +.B bg +command to continue it in the background, the +.B fg +command to continue it in the foreground, or +the +.B kill +command to kill it. A \fB^Z\fP takes effect immediately, +and has the additional side effect of causing pending output +and typeahead to be discarded. +.PP +There are a number of ways to refer to a job in the shell. +The character +.B % +introduces a job name. Job number +.I n +may be referred to as +.BR %n . +A job may also be referred to using a prefix of the name used to +start it, or using a substring that appears in its command line. +For example, +.B %ce +refers to a stopped +.B ce +job. If a prefix matches more than one job, +.B bash +reports an error. Using +.BR %?ce , +on the other hand, refers to any job containing the string +.B ce +in its command line. If the substring matches more than one job, +.B bash +reports an error. The symbols +.B %% +and +.B %+ +refer to the shell's notion of the +.IR "current job" , +which is the last job stopped while it was in +the foreground or started in the background. +The +.I "previous job" +may be referenced using +.BR %\- . +In output pertaining to jobs (e.g., the output of the +.B jobs +command), the current job is always flagged with a +.BR + , +and the previous job with a +.BR \- . +.PP +Simply naming a job can be used to bring it into the +foreground: +.B %1 +is a synonym for +\fB``fg %1''\fP, +bringing job 1 from the background into the foreground. +Similarly, +.B ``%1 &'' +resumes job 1 in the background, equivalent to +\fB``bg %1''\fP. +.PP +The shell learns immediately whenever a job changes state. +Normally, +.B bash +waits until it is about to print a prompt before reporting +changes in a job's status so as to not interrupt +any other output. If the +.B \-b +option to the +.B set +builtin command +is enabled, +.B bash +reports such changes immediately. +Any trap on +.SM +.B SIGCHLD +is executed for each child that exits. +.PP +If an attempt to exit +.B bash +is made while jobs are stopped, the shell prints a warning message. The +.B jobs +command may then be used to inspect their status. +If a second attempt to exit is made without an intervening command, +the shell does not print another warning, and the stopped +jobs are terminated. +.SH PROMPTING +When executing interactively, +.B bash +displays the primary prompt +.SM +.B PS1 +when it is ready to read a command, and the secondary prompt +.SM +.B PS2 +when it needs more input to complete a command. +.B Bash +allows these prompt strings to be customized by inserting a number of +backslash-escaped special characters that are decoded as follows: +.RS +.PD 0 +.TP +.B \ea +an ASCII bell character (07) +.TP +.B \ed +the date in "Weekday Month Date" format (e.g., "Tue May 26") +.TP +.B \eD{\fIformat\fP} +the \fIformat\fP is passed to \fIstrftime\fP(3) and the result is inserted +into the prompt string; an empty \fIformat\fP results in a locale-specific +time representation. The braces are required +.TP +.B \ee +an ASCII escape character (033) +.TP +.B \eh +the hostname up to the first `.' +.TP +.B \eH +the hostname +.TP +.B \ej +the number of jobs currently managed by the shell +.TP +.B \el +the basename of the shell's terminal device name +.TP +.B \en +newline +.TP +.B \er +carriage return +.TP +.B \es +the name of the shell, the basename of +.B $0 +(the portion following the final slash) +.TP +.B \et +the current time in 24-hour HH:MM:SS format +.TP +.B \eT +the current time in 12-hour HH:MM:SS format +.TP +.B \e@ +the current time in 12-hour am/pm format +.TP +.B \eA +the current time in 24-hour HH:MM format +.TP +.B \eu +the username of the current user +.TP +.B \ev +the version of \fBbash\fP (e.g., 2.00) +.TP +.B \eV +the release of \fBbash\fP, version + patchelvel (e.g., 2.00.0) +.TP +.B \ew +the current working directory +.TP +.B \eW +the basename of the current working directory +.TP +.B \e! +the history number of this command +.TP +.B \e# +the command number of this command +.TP +.B \e$ +if the effective UID is 0, a +.BR # , +otherwise a +.B $ +.TP +.B \e\fInnn\fP +the character corresponding to the octal number \fInnn\fP +.TP +.B \e\e +a backslash +.TP +.B \e[ +begin a sequence of non-printing characters, which could be used to +embed a terminal control sequence into the prompt +.TP +.B \e] +end a sequence of non-printing characters +.PD +.RE +.PP +The command number and the history number are usually different: +the history number of a command is its position in the history +list, which may include commands restored from the history file +(see +.SM +.B HISTORY +below), while the command number is the position in the sequence +of commands executed during the current shell session. +After the string is decoded, it is expanded via +parameter expansion, command substitution, arithmetic +expansion, and quote removal, subject to the value of the +.B promptvars +shell option (see the description of the +.B shopt +command under +.SM +.B "SHELL BUILTIN COMMANDS" +below). +.SH READLINE +This is the library that handles reading input when using an interactive +shell, unless the +.B \-\-noediting +option is given at shell invocation. +By default, the line editing commands are similar to those of emacs. +A vi-style line editing interface is also available. +To turn off line editing after the shell is running, use the +.B +o emacs +or +.B +o vi +options to the +.B set +builtin (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.SS "Readline Notation" +.PP +In this section, the emacs-style notation is used to denote +keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n +means Control\-N. Similarly, +.I meta +keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards +without a +.I meta +key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key +then the +.I x +key. This makes ESC the \fImeta prefix\fP. +The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP, +or press the Escape key +then hold the Control key while pressing the +.I x +key.) +.PP +Readline commands may be given numeric +.IR arguments , +which normally act as a repeat count. +Sometimes, however, it is the sign of the argument that is significant. +Passing a negative argument to a command that acts in the forward +direction (e.g., \fBkill\-line\fP) causes that command to act in a +backward direction. +Commands whose behavior with arguments deviates from this are noted +below. +.PP +When a command is described as \fIkilling\fP text, the text +deleted is saved for possible future retrieval +(\fIyanking\fP). The killed text is saved in a +\fIkill ring\fP. Consecutive kills cause the text to be +accumulated into one unit, which can be yanked all at once. +Commands which do not kill text separate the chunks of text +on the kill ring. +.SS "Readline Initialization" +.PP +Readline is customized by putting commands in an initialization +file (the \fIinputrc\fP file). +The name of this file is taken from the value of the +.SM +.B INPUTRC +variable. If that variable is unset, the default is +.IR ~/.inputrc . +When a program which uses the readline library starts up, the +initialization file is read, and the key bindings and variables +are set. +There are only a few basic constructs allowed in the +readline initialization file. +Blank lines are ignored. +Lines beginning with a \fB#\fP are comments. +Lines beginning with a \fB$\fP indicate conditional constructs. +Other lines denote key bindings and variable settings. +.PP +The default key-bindings may be changed with an +.I inputrc +file. +Other programs that use this library may add their own commands +and bindings. +.PP +For example, placing +.RS +.PP +M\-Control\-u: universal\-argument +.RE +or +.RS +C\-Meta\-u: universal\-argument +.RE +into the +.I inputrc +would make M\-C\-u execute the readline command +.IR universal\-argument . +.PP +The following symbolic character names are recognized: +.IR RUBOUT , +.IR DEL , +.IR ESC , +.IR LFD , +.IR NEWLINE , +.IR RET , +.IR RETURN , +.IR SPC , +.IR SPACE , +and +.IR TAB . +.PP +In addition to command names, readline allows keys to be bound +to a string that is inserted when the key is pressed (a \fImacro\fP). +.SS "Readline Key Bindings" +.PP +The syntax for controlling key bindings in the +.I inputrc +file is simple. All that is required is the name of the +command or the text of a macro and a key sequence to which +it should be bound. The name may be specified in one of two ways: +as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP +prefixes, or as a key sequence. +.PP +When using the form \fBkeyname\fP:\^\fIfunction\-name\fP or \fImacro\fP, +.I keyname +is the name of a key spelled out in English. For example: +.sp +.RS +Control-u: universal\-argument +.br +Meta-Rubout: backward-kill-word +.br +Control-o: "> output" +.RE +.LP +In the above example, +.I C\-u +is bound to the function +.BR universal\-argument , +.I M\-DEL +is bound to the function +.BR backward\-kill\-word , +and +.I C\-o +is bound to run the macro +expressed on the right hand side (that is, to insert the text +.if t \f(CW> output\fP +.if n ``> output'' +into the line). +.PP +In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP, +.B keyseq +differs from +.B keyname +above in that strings denoting +an entire key sequence may be specified by placing the sequence +within double quotes. Some GNU Emacs style key escapes can be +used, as in the following example, but the symbolic character names +are not recognized. +.sp +.RS +"\eC\-u": universal\-argument +.br +"\eC\-x\eC\-r": re\-read\-init\-file +.br +"\ee[11~": "Function Key 1" +.RE +.PP +In this example, +.I C\-u +is again bound to the function +.BR universal\-argument . +.I "C\-x C\-r" +is bound to the function +.BR re\-read\-init\-file , +and +.I "ESC [ 1 1 ~" +is bound to insert the text +.if t \f(CWFunction Key 1\fP. +.if n ``Function Key 1''. +.PP +The full set of GNU Emacs style escape sequences is +.RS +.PD 0 +.TP +.B \eC\- +control prefix +.TP +.B \eM\- +meta prefix +.TP +.B \ee +an escape character +.TP +.B \e\e +backslash +.TP +.B \e" +literal " +.TP +.B \e' +literal ' +.RE +.PD +.PP +In addition to the GNU Emacs style escape sequences, a second +set of backslash escapes is available: +.RS +.PD 0 +.TP +.B \ea +alert (bell) +.TP +.B \eb +backspace +.TP +.B \ed +delete +.TP +.B \ef +form feed +.TP +.B \en +newline +.TP +.B \er +carriage return +.TP +.B \et +horizontal tab +.TP +.B \ev +vertical tab +.TP +.B \e\fInnn\fP +the eight-bit character whose value is the octal value \fInnn\fP +(one to three digits) +.TP +.B \ex\fIHH\fP +the eight-bit character whose value is the hexadecimal value \fIHH\fP +(one or two hex digits) +.RE +.PD +.PP +When entering the text of a macro, single or double quotes must +be used to indicate a macro definition. +Unquoted text is assumed to be a function name. +In the macro body, the backslash escapes described above are expanded. +Backslash will quote any other character in the macro text, +including " and '. +.PP +.B Bash +allows the current readline key bindings to be displayed or modified +with the +.B bind +builtin command. The editing mode may be switched during interactive +use by using the +.B \-o +option to the +.B set +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). +.SS "Readline Variables" +.PP +Readline has variables that can be used to further customize its +behavior. A variable may be set in the +.I inputrc +file with a statement of the form +.RS +.PP +\fBset\fP \fIvariable\-name\fP \fIvalue\fP +.RE +.PP +Except where noted, readline variables can take the values +.B On +or +.BR Off . +The variables and their default values are: +.PP +.PD 0 +.TP +.B bell\-style (audible) +Controls what happens when readline wants to ring the terminal bell. +If set to \fBnone\fP, readline never rings the bell. If set to +\fBvisible\fP, readline uses a visible bell if one is available. +If set to \fBaudible\fP, readline attempts to ring the terminal's bell. +.TP +.B comment\-begin (``#'') +The string that is inserted when the readline +.B insert\-comment +command is executed. +This command is bound to +.B M\-# +in emacs mode and to +.B # +in vi command mode. +.TP +.B completion\-ignore\-case (Off) +If set to \fBOn\fP, readline performs filename matching and completion +in a case\-insensitive fashion. +.TP +.B completion\-query\-items (100) +This determines when the user is queried about viewing +the number of possible completions +generated by the \fBpossible\-completions\fP command. +It may be set to any integer value greater than or equal to +zero. If the number of possible completions is greater than +or equal to the value of this variable, the user is asked whether +or not he wishes to view them; otherwise they are simply listed +on the terminal. +.TP +.B convert\-meta (On) +If set to \fBOn\fP, readline will convert characters with the +eighth bit set to an ASCII key sequence +by stripping the eighth bit and prefixing an +escape character (in effect, using escape as the \fImeta prefix\fP). +.TP +.B disable\-completion (Off) +If set to \fBOn\fP, readline will inhibit word completion. Completion +characters will be inserted into the line as if they had been +mapped to \fBself-insert\fP. +.TP +.B editing\-mode (emacs) +Controls whether readline begins with a set of key bindings similar +to \fIemacs\fP or \fIvi\fP. +.B editing\-mode +can be set to either +.B emacs +or +.BR vi . +.TP +.B enable\-keypad (Off) +When set to \fBOn\fP, readline will try to enable the application +keypad when it is called. Some systems need this to enable the +arrow keys. +.TP +.B expand\-tilde (Off) +If set to \fBon\fP, tilde expansion is performed when readline +attempts word completion. +.TP +.B history-preserve-point +If set to \fBon\fP, the history code attempts to place point at the +same location on each history line retrived with \fBprevious-history\fP +or \fBnext-history\fP. +.TP +.B horizontal\-scroll\-mode (Off) +When set to \fBOn\fP, makes readline use a single line for display, +scrolling the input horizontally on a single screen line when it +becomes longer than the screen width rather than wrapping to a new line. +.TP +.B input\-meta (Off) +If set to \fBOn\fP, readline will enable eight-bit input (that is, +it will not strip the high bit from the characters it reads), +regardless of what the terminal claims it can support. The name +.B meta\-flag +is a synonym for this variable. +.TP +.B isearch\-terminators (``C\-[C\-J'') +The string of characters that should terminate an incremental +search without subsequently executing the character as a command. +If this variable has not been given a value, the characters +\fIESC\fP and \fIC\-J\fP will terminate an incremental search. +.TP +.B keymap (emacs) +Set the current readline keymap. The set of valid keymap names is +\fIemacs, emacs\-standard, emacs\-meta, emacs\-ctlx, vi, +vi\-command\fP, and +.IR vi\-insert . +\fIvi\fP is equivalent to \fIvi\-command\fP; \fIemacs\fP is +equivalent to \fIemacs\-standard\fP. The default value is +.IR emacs ; +the value of +.B editing\-mode +also affects the default keymap. +.TP +.B mark\-directories (On) +If set to \fBOn\fP, completed directory names have a slash +appended. +.TP +.B mark\-modified\-lines (Off) +If set to \fBOn\fP, history lines that have been modified are displayed +with a preceding asterisk (\fB*\fP). +.TP +.B mark\-symlinked\-directories (Off) +If set to \fBOn\fP, completed names which are symbolic links to directories +have a slash appended (subject to the value of +\fBmark\-directories\fP). +.TP +.B match\-hidden\-files (On) +This variable, when set to \fBOn\fP, causes readline to match files whose +names begin with a `.' (hidden files) when performing filename +completion, unless the leading `.' is +supplied by the user in the filename to be completed. +.TP +.B output\-meta (Off) +If set to \fBOn\fP, readline will display characters with the +eighth bit set directly rather than as a meta-prefixed escape +sequence. +.TP +.B page\-completions (On) +If set to \fBOn\fP, readline uses an internal \fImore\fP-like pager +to display a screenful of possible completions at a time. +.TP +.B print\-completions\-horizontally (Off) +If set to \fBOn\fP, readline will display completions with matches +sorted horizontally in alphabetical order, rather than down the screen. +.TP +.B show\-all\-if\-ambiguous (Off) +This alters the default behavior of the completion functions. If +set to +.BR on , +words which have more than one possible completion cause the +matches to be listed immediately instead of ringing the bell. +.TP +.B visible\-stats (Off) +If set to \fBOn\fP, a character denoting a file's type as reported +by \fIstat\fP(2) is appended to the filename when listing possible +completions. +.PD +.SS "Readline Conditional Constructs" +.PP +Readline implements a facility similar in spirit to the conditional +compilation features of the C preprocessor which allows key +bindings and variable settings to be performed as the result +of tests. There are four parser directives used. +.IP \fB$if\fP +The +.B $if +construct allows bindings to be made based on the +editing mode, the terminal being used, or the application using +readline. The text of the test extends to the end of the line; +no characters are required to isolate it. +.RS +.IP \fBmode\fP +The \fBmode=\fP form of the \fB$if\fP directive is used to test +whether readline is in emacs or vi mode. +This may be used in conjunction +with the \fBset keymap\fP command, for instance, to set bindings in +the \fIemacs\-standard\fP and \fIemacs\-ctlx\fP keymaps only if +readline is starting out in emacs mode. +.IP \fBterm\fP +The \fBterm=\fP form may be used to include terminal-specific +key bindings, perhaps to bind the key sequences output by the +terminal's function keys. The word on the right side of the +.B = +is tested against the both full name of the terminal and the portion +of the terminal name before the first \fB\-\fP. This allows +.I sun +to match both +.I sun +and +.IR sun\-cmd , +for instance. +.IP \fBapplication\fP +The \fBapplication\fP construct is used to include +application-specific settings. Each program using the readline +library sets the \fIapplication name\fP, and an initialization +file can test for a particular value. +This could be used to bind key sequences to functions useful for +a specific program. For instance, the following command adds a +key sequence that quotes the current or previous word in Bash: +.sp 1 +.RS +.nf +\fB$if\fP Bash +# Quote the current or previous word +"\eC\-xq": "\eeb\e"\eef\e"" +\fB$endif\fP +.fi +.RE +.RE +.IP \fB$endif\fP +This command, as seen in the previous example, terminates an +\fB$if\fP command. +.IP \fB$else\fP +Commands in this branch of the \fB$if\fP directive are executed if +the test fails. +.IP \fB$include\fP +This directive takes a single filename as an argument and reads commands +and bindings from that file. For example, the following directive +would read \fI/etc/inputrc\fP: +.sp 1 +.RS +.nf +\fB$include\fP \^ \fI/etc/inputrc\fP +.fi +.RE +.SS Searching +.PP +Readline provides commands for searching through the command history +(see +.SM +.B HISTORY +below) for lines containing a specified string. +There are two search modes: +.I incremental +and +.IR non-incremental . +.PP +Incremental searches begin before the user has finished typing the +search string. +As each character of the search string is typed, readline displays +the next entry from the history matching the string typed so far. +An incremental search requires only as many characters as needed to +find the desired history entry. +The characters present in the value of the \fBisearch-terminators\fP +variable are used to terminate an incremental search. +If that variable has not been assigned a value the Escape and +Control-J characters will terminate an incremental search. +Control-G will abort an incremental search and restore the original +line. +When the search is terminated, the history entry containing the +search string becomes the current line. +.PP +To find other matching entries in the history list, type Control-S or +Control-R as appropriate. +This will search backward or forward in the history for the next +entry matching the search string typed so far. +Any other key sequence bound to a readline command will terminate +the search and execute that command. +For instance, a \fInewline\fP will terminate the search and accept +the line, thereby executing the command from the history list. +.PP +Readline remembers the last incremental search string. If two +Control-Rs are typed without any intervening characters defining a +new search string, any remembered search string is used. +.PP +Non-incremental searches read the entire search string before starting +to search for matching history lines. The search string may be +typed by the user or be part of the contents of the current line. +.SS "Readline Command Names" +.PP +The following is a list of the names of the commands and the default +key sequences to which they are bound. +Command names without an accompanying key sequence are unbound by default. +In the following descriptions, \fIpoint\fP refers to the current cursor +position, and \fImark\fP refers to a cursor position saved by the +\fBset\-mark\fP command. +The text between the point and mark is referred to as the \fIregion\fP. +.SS Commands for Moving +.PP +.PD 0 +.TP +.B beginning\-of\-line (C\-a) +Move to the start of the current line. +.TP +.B end\-of\-line (C\-e) +Move to the end of the line. +.TP +.B forward\-char (C\-f) +Move forward a character. +.TP +.B backward\-char (C\-b) +Move back a character. +.TP +.B forward\-word (M\-f) +Move forward to the end of the next word.

the function or command has complete freedom in generating +the matches. +.PP +Any function specified with \fB\-F\fP is invoked first. +The function may use any of the shell facilities, including the +\fBcompgen\fP builtin described below, to generate the matches. +It must put the possible completions in the +.SM +.B COMPREPLY +array variable. +.PP +Next, any command specified with the \fB\-C\fP option is invoked +in an environment equivalent to command substitution. +It should print a list of completions, one per line, to the +standard output. +Backslash may be used to escape a newline, if necessary. +.PP +After all of the possible completions are generated, any filter +specified with the \fB\-X\fP option is applied to the list. +The filter is a pattern as used for pathname expansion; a \fB&\fP +in the pattern is replaced with the text of the word being completed. +A literal \fB&\fP may be escaped with a backslash; the backslash +is removed before attempting a match. +Any completion that matches the pattern will be removed from the list. +A leading \fB!\fP negates the pattern; in this case any completion +not matching the pattern will be removed. +.PP +Finally, any prefix and suffix specified with the \fB\-P\fP and \fB\-S\fP +options are added to each member of the completion list, and the result is +returned to the readline completion code as the list of possible +completions. +.PP +If the previously-applied actions do not generate any matches, and the +\fB\-o dirnames\fP option was supplied to \fBcomplete\fP when the +compspec was defined, directory name completion is attempted. +.PP +By default, if a compspec is found, whatever it generates is returned +to the completion code as the full set of possible completions. +The default \fBbash\fP completions are not attempted, and the readline +default of filename completion is disabled. +If the \fB-o default\fP option was supplied to \fBcomplete\fP when the +compspec was defined, readline's default completion will be performed +if the compspec generates no matches. +.PP +When a compspec indicates that directory name completion is desired, +the programmable completion functions force readline to append a slash +to completed names which are symbolic links to directories, subject to +the value of the \fBmark\-directories\fP readline variable, regardless +of the setting of the \fBmark-symlinked\-directories\fP readline variable. +.SH HISTORY +When the +.B \-o history +option to the +.B set +builtin is enabled, the shell provides access to the +\fIcommand history\fP, +the list of commands previously typed. +The value of the \fBHISTSIZE\fP variable is used as the +number of commands to save in a history list. +The text of the last +.SM +.B HISTSIZE +commands (default 500) is saved. The shell +stores each command in the history list prior to parameter and +variable expansion (see +.SM +.B EXPANSION +above) but after history expansion is performed, subject to the +values of the shell variables +.SM +.B HISTIGNORE +and +.SM +.BR HISTCONTROL . +.PP +On startup, the history is initialized from the file named by +the variable +.SM +.B HISTFILE +(default \fI~/.bash_history\fP). +The file named by the value of +.SM +.B HISTFILE +is truncated, if necessary, to contain no more than +the number of lines specified by the value of +.SM +.BR HISTFILESIZE . +When an interactive shell exits, the last +.SM +.B $HISTSIZE +lines are copied from the history list to +.SM +.BR $HISTFILE . +If the +.B histappend +shell option is enabled +(see the description of +.B shopt +under +.SM +.B "SHELL BUILTIN COMMANDS" +below), the lines are appended to the history file, +otherwise the history file is overwritten. +If +.SM +.B HISTFILE +is unset, or if the history file is unwritable, the history is +not saved. After saving the history, the history file is truncated +to contain no more than +.SM +.B HISTFILESIZE +lines. If +.SM +.B HISTFILESIZE +is not set, no truncation is performed. +.PP +The builtin command +.B fc +(see +.SM +.B SHELL BUILTIN COMMANDS +below) may be used to list or edit and re-execute a portion of +the history list. +The +.B history +builtin may be used to display or modify the history list and +manipulate the history file. +When using command-line editing, search commands +are available in each editing mode that provide access to the +history list. +.PP +The shell allows control over which commands are saved on the history +list. The +.SM +.B HISTCONTROL +and +.SM +.B HISTIGNORE +variables may be set to cause the shell to save only a subset of the +commands entered. +The +.B cmdhist +shell option, if enabled, causes the shell to attempt to save each +line of a multi-line command in the same history entry, adding +semicolons where necessary to preserve syntactic correctness. +The +.B lithist +shell option causes the shell to save the command with embedded newlines +instead of semicolons. See the description of the +.B shopt +builtin below under +.SM +.B "SHELL BUILTIN COMMANDS" +for information on setting and unsetting shell options. +.SH "HISTORY EXPANSION" +.PP +The shell supports a history expansion feature that +is similar to the history expansion in +.BR csh. +This section describes what syntax features are available. This +feature is enabled by default for interactive shells, and can be +disabled using the +.B \+H +option to the +.B set +builtin command (see +.SM +.B SHELL BUILTIN COMMANDS +below). Non-interactive shells do not perform history expansion +by default. +.PP +History expansions introduce words from the history list into +the input stream, making it easy to repeat commands, insert the +arguments to a previous command into the current input line, or +fix errors in previous commands quickly. +.PP +History expansion is performed immediately after a complete line +is read, before the shell breaks it into words. +It takes place in two parts. +The first is to determine which line from the history list +to use during substitution. +The second is to select portions of that line for inclusion into +the current one. +The line selected from the history is the \fIevent\fP, +and the portions of that line that are acted upon are \fIwords\fP. +Various \fImodifiers\fP are available to manipulate the selected words. +The line is broken into words in the same fashion as when reading input, +so that several \fImetacharacter\fP-separated words surrounded by +quotes are considered one word. +History expansions are introduced by the appearance of the +history expansion character, which is \^\fB!\fP\^ by default. +Only backslash (\^\fB\e\fP\^) and single quotes can quote +the history expansion character. +.PP +Several shell options settable with the +.B shopt +builtin may be used to tailor the behavior of history expansion. +If the +.B histverify +shell option is enabled (see the description of the +.B shopt +builtin), and +.B readline +is being used, history substitutions are not immediately passed to +the shell parser. +Instead, the expanded line is reloaded into the +.B readline +editing buffer for further modification. +If +.B readline +is being used, and the +.B histreedit +shell option is enabled, a failed history substitution will be reloaded +into the +.B readline +editing buffer for correction. +The +.B \-p +option to the +.B history +builtin command may be used to see what a history expansion will +do before using it. +The +.B \-s +option to the +.B history +builtin may be used to add commands to the end of the history list +without actually executing them, so that they are available for +subsequent recall. +.PP +The shell allows control of the various characters used by the +history expansion mechanism (see the description of +.B histchars +above under +.BR "Shell Variables" ). +.SS Event Designators +.PP +An event designator is a reference to a command line entry in the +history list. +.PP +.PD 0 +.TP +.B ! +Start a history substitution, except when followed by a +.BR blank , +newline, = or ( (when the \fBextglob\fP shell option is enabled using +the \fBshopt\fP builtin). +.TP +.B !\fIn\fR +Refer to command line +.IR n . +.TP +.B !\-\fIn\fR +Refer to the current command line minus +.IR n . +.TP +.B !! +Refer to the previous command.

NAME

+ +bash - GNU Bourne-Again SHell +  +

SYNOPSIS

+ +bash + +[options] +[file] +  +

COPYRIGHT

+ + +Bash is Copyright © 1989-2005 by the Free Software Foundation, Inc. +  +

DESCRIPTION

+ +Bash + +is an sh-compatible command language interpreter that +executes commands read from the standard input or from a file. +Bash + +also incorporates useful features from the Korn and C +shells (ksh and csh). +

+ +Bash + +is intended to be a conformant implementation of the +Shell and Utilities portion of the IEEE POSIX specification +(IEEE Standard 1003.1). +Bash + +can be configured to be POSIX-conformant by default. +  +

OPTIONS

+ +In addition to the single-character shell options documented in the +description of the set builtin command, bash +interprets the following options when it is invoked: +

+ + +

+
-c string + +
+If the +-c + +option is present, then commands are read from +string. + +If there are arguments after the +string, + +they are assigned to the positional parameters, starting with +$0. + +
-i + +
+If the +-i + +option is present, the shell is +interactive. + +
-l + +
+Make +bash + +act as if it had been invoked as a login shell (see +INVOCATION + + +below). +
-r + +
+If the +-r + +option is present, the shell becomes +restricted + +(see +RESTRICTED SHELL + + +below). +
-s + +
+If the +-s + +option is present, or if no arguments remain after option +processing, then commands are read from the standard input. +This option allows the positional parameters to be set +when invoking an interactive shell. +
-D + +
+A list of all double-quoted strings preceded by $ +is printed on the standard output. +These are the strings that +are subject to language translation when the current locale +is not C or POSIX. +This implies the -n option; no commands will be executed. +
[-+]O [shopt_option] + +
+shopt_option is one of the shell options accepted by the +shopt builtin (see +SHELL BUILTIN COMMANDS + + +below). +If shopt_option is present, -O sets the value of that option; ++O unsets it. +If shopt_option is not supplied, the names and values of the shell +options accepted by shopt are printed on the standard output. +If the invocation option is +O, the output is displayed in a format +that may be reused as input. +
-- + +
+A +-- + +signals the end of options and disables further option processing. +Any arguments after the +-- + +are treated as filenames and arguments. An argument of +- + +is equivalent to --. + +
+

+ +Bash + +also interprets a number of multi-character options. +These options must appear on the command line before the +single-character options to be recognized. +

+ + +

+
--debugger + +
+Arrange for the debugger profile to be executed before the shell +starts. +Turns on extended debugging mode (see the description of the +extdebug + +option to the +shopt + +builtin below) +and shell function tracing (see the description of the +-o functrace option to the +set + +builtin below). +
--dump-po-strings + +
+Equivalent to -D, but the output is in the GNU gettext +po (portable object) file format. +
--dump-strings + +
+Equivalent to -D. +
--help + +
+Display a usage message on standard output and exit successfully. +
--init-file file
+ +
--rcfile file
+ +Execute commands from +file + +instead of the standard personal initialization file +~/.bashrc + +if the shell is interactive (see +INVOCATION + + +below). +
--login + +
+Equivalent to -l. +
--noediting + +
+Do not use the GNU +readline + +library to read command lines when the shell is interactive. +
--noprofile + +
+Do not read either the system-wide startup file + +/etc/profile + +or any of the personal initialization files +~/.bash_profile, + +~/.bash_login, + +or +~/.profile. + +By default, +bash + +reads these files when it is invoked as a login shell (see +INVOCATION + + +below). +
--norc + +
+Do not read and execute the personal initialization file +~/.bashrc + +if the shell is interactive. +This option is on by default if the shell is invoked as +sh. + +
--posix + +
+Change the behavior of bash where the default operation differs +from the POSIX standard to match the standard (posix mode). +
--restricted + +
+The shell becomes restricted (see +RESTRICTED SHELL + + +below). +
--verbose + +
+Equivalent to -v. +
--version + +
+Show version information for this instance of +bash + +on the standard output and exit successfully. + +
+  +

ARGUMENTS

+ +If arguments remain after option processing, and neither the +-c + +nor the +-s + +option has been supplied, the first argument is assumed to +be the name of a file containing shell commands. +If +bash + +is invoked in this fashion, +$0 + +is set to the name of the file, and the positional parameters +are set to the remaining arguments. +Bash + +reads and executes commands from this file, then exits. +Bash's exit status is the exit status of the last command +executed in the script. +If no commands are executed, the exit status is 0. +An attempt is first made to open the file in the current directory, and, +if no file is found, then the shell searches the directories in +PATH + + +for the script. +  +

INVOCATION

+ +A login shell is one whose first character of argument zero is a +-, + +or one started with the +--login + +option. +

+ +An interactive shell is one started without non-option arguments +and without the +-c + +option +whose standard input and error are +both connected to terminals (as determined by +isatty(3)), + +or one started with the +-i + +option. +PS1 + + +is set and +$- + +includes +i + +if +bash + +is interactive, +allowing a shell script or a startup file to test this state. +

+ +The following paragraphs describe how +bash + +executes its startup files. +If any of the files exist but cannot be read, +bash + +reports an error. +Tildes are expanded in file names as described below under +Tilde Expansion + +in the +EXPANSION + + +section. +

+ +When +bash + +is invoked as an interactive login shell, or as a non-interactive shell +with the --login option, it first reads and +executes commands from the file /etc/profile, if that +file exists. +After reading that file, it looks for ~/.bash_profile, +~/.bash_login, and ~/.profile, in that order, and reads +and executes commands from the first one that exists and is readable. +The +--noprofile + +option may be used when the shell is started to inhibit this behavior. +

+ +When a login shell exits, +bash + +reads and executes commands from the file ~/.bash_logout, if it +exists. +

+ +When an interactive shell that is not a login shell is started, +bash + +reads and executes commands from ~/.bashrc, if that file exists. +This may be inhibited by using the +--norc + +option. +The --rcfile file option will force +bash + +to read and execute commands from file instead of ~/.bashrc. +

+ +When +bash + +is started non-interactively, to run a shell script, for example, it +looks for the variable +BASH_ENV + + +in the environment, expands its value if it appears there, and uses the +expanded value as the name of a file to read and execute. +Bash + +behaves as if the following command were executed: +

+

+if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi + +
+ +

+but the value of the +PATH + + +variable is not used to search for the file name. +

+ +If +bash + +is invoked with the name +sh, + +it tries to mimic the startup behavior of historical versions of +sh + +as closely as possible, +while conforming to the POSIX standard as well. +When invoked as an interactive login shell, or a non-interactive +shell with the --login option, it first attempts to +read and execute commands from +/etc/profile + +and +~/.profile, + +in that order. +The +--noprofile + +option may be used to inhibit this behavior. +When invoked as an interactive shell with the name +sh, + +bash + +looks for the variable +ENV, + + +expands its value if it is defined, and uses the +expanded value as the name of a file to read and execute. +Since a shell invoked as +sh + +does not attempt to read and execute commands from any other startup +files, the +--rcfile + +option has no effect. +A non-interactive shell invoked with the name +sh + +does not attempt to read any other startup files. +When invoked as +sh, + +bash + +enters +posix + +mode after the startup files are read. +

+ +When +bash + +is started in +posix + +mode, as with the +--posix + +command line option, it follows the POSIX standard for startup files. +In this mode, interactive shells expand the +ENV + + +variable and commands are read and executed from the file +whose name is the expanded value. +No other startup files are read. +

+ +Bash + +attempts to determine when it is being run by the remote shell +daemon, usually rshd. +If +bash + +determines it is being run by rshd, it reads and executes +commands from ~/.bashrc, if that file exists and is readable. +It will not do this if invoked as sh. +The +--norc + +option may be used to inhibit this behavior, and the +--rcfile + +option may be used to force another file to be read, but +rshd does not generally invoke the shell with those options +or allow them to be specified. +

+ +If the shell is started with the effective user (group) id not equal to the +real user (group) id, and the -p option is not supplied, no startup +files are read, shell functions are not inherited from the environment, the +SHELLOPTS + + +variable, if it appears in the environment, is ignored, +and the effective user id is set to the real user id. +If the -p option is supplied at invocation, the startup behavior is +the same, but the effective user id is not reset. +  +

DEFINITIONS

+ +

+ +The following definitions are used throughout the rest of this +document. + +

+
blank + +
+A space or tab. +
word + +
+A sequence of characters considered as a single unit by the shell. +Also known as a +token. + +
name + +
+A +word + +consisting only of alphanumeric characters and underscores, and +beginning with an alphabetic character or an underscore. Also +referred to as an +identifier. + +
metacharacter + +
+A character that, when unquoted, separates words. One of the following: +
+ +
+

+ +| & ; ( ) < > space tab + +

+ +
+

+ +

+
control operator + +
+A token that performs a control function. It is one of the following +symbols: +
+

+ +|| & && ; ;; ( ) | <newline> + +

+ + +
+  +

RESERVED WORDS

+ +Reserved words are words that have a special meaning to the shell. +The following words are recognized as reserved when unquoted and either +the first word of a simple command (see +SHELL GRAMMAR + + +below) or the third word of a +case + +or +for + +command: +
+ +

+ + + + +! case do done elif else esac fi for function if in select then until while { } time [[ ]] +

+ + +  +

SHELL GRAMMAR

+ +  +

Simple Commands

+ +

+ +A simple command is a sequence of optional variable assignments +followed by blank-separated words and redirections, and +terminated by a control operator. The first word +specifies the command to be executed, and is passed as argument zero. +The remaining words are passed as arguments to the invoked command. +

+ +The return value of a simple command is its exit status, or +128+n if the command is terminated by signal +n. + +  +

Pipelines

+ +

+ +A pipeline is a sequence of one or more commands separated by +the character +|. + +The format for a pipeline is: +

+

+ +[time [-p]] [ ! ] command [ | command2 ... ] +

+ +

+ +The standard output of +command + +is connected via a pipe to the standard input of +command2. + +This connection is performed before any redirections specified by the +command (see +REDIRECTION + + +below). +

+ +The return status of a pipeline is the exit status of the last +command, unless the pipefail option is enabled. +If pipefail is enabled, the pipeline's return status is the +value of the last (rightmost) command to exit with a non-zero status, +or zero if all commands exit successfully. +If the reserved word +! + +precedes a pipeline, the exit status of that pipeline is the logical +negation of the exit status as described above. +The shell waits for all commands in the pipeline to +terminate before returning a value. +

+ +If the +time + +reserved word precedes a pipeline, the elapsed as well as user and +system time consumed by its execution are reported when the pipeline +terminates. +The -p option changes the output format to that specified by POSIX. +The +TIMEFORMAT + + +variable may be set to a format string that specifies how the timing +information should be displayed; see the description of +TIMEFORMAT + + +under +Shell Variables + +below. +

+ +Each command in a pipeline is executed as a separate process (i.e., in a +subshell). +  +

Lists

+ +

+ +A list is a sequence of one or more pipelines separated by one +of the operators +;, + +&, + +&&, + +or +||, + +and optionally terminated by one of +;, + +&, + +or +<newline>. + +

+ +Of these list operators, +&& + +and +|| + +have equal precedence, followed by +; + +and +&, + +which have equal precedence. +

+ +A sequence of one or more newlines may appear in a list instead +of a semicolon to delimit commands. +

+ +If a command is terminated by the control operator +&, + +the shell executes the command in the background +in a subshell. The shell does not wait for the command to +finish, and the return status is 0. Commands separated by a +; + +are executed sequentially; the shell waits for each +command to terminate in turn. The return status is the +exit status of the last command executed. +

+ +The control operators +&& + +and +|| + +denote AND lists and OR lists, respectively. +An AND list has the form +

+

+ +command1 && command2 +

+ +

+ +command2 + +is executed if, and only if, +command1 + +returns an exit status of zero. +

+ +An OR list has the form +

+

+ +command1 || command2 +

+ +

+ +

+ +command2 + +is executed if and only if +command1 + +returns a non-zero exit status. The return status of +AND and OR lists is the exit status of the last command +executed in the list. +  +

Compound Commands

+ +

+ +A compound command is one of the following: +

+
(list)
+list is executed in a subshell environment (see +COMMAND EXECUTION ENVIRONMENT +below). +Variable assignments and builtin +commands that affect the shell's environment do not remain in effect +after the command completes. The return status is the exit status of +list. +
{ list; }
+list is simply executed in the current shell environment. +list must be terminated with a newline or semicolon. +This is known as a group command. +The return status is the exit status of +list. +Note that unlike the metacharacters ( and ), { and +} are reserved words and must occur where a reserved +word is permitted to be recognized. Since they do not cause a word +break, they must be separated from list by whitespace. +
((expression))
+The expression is evaluated according to the rules described +below under +ARITHMETIC EVALUATION. + + +If the value of the expression is non-zero, the return status is 0; +otherwise the return status is 1. This is exactly equivalent to +let "expression". +
[[ expression ]]
+Return a status of 0 or 1 depending on the evaluation of +the conditional expression expression. +Expressions are composed of the primaries described below under +CONDITIONAL EXPRESSIONS. + + +Word splitting and pathname expansion are not performed on the words +between the [[ and ]]; tilde expansion, parameter and +variable expansion, arithmetic expansion, command substitution, process +substitution, and quote removal are performed. +Conditional operators such as -f must be unquoted to be recognized +as primaries. +

+ + +When the == and != operators are used, the string to the +right of the operator is considered a pattern and matched according +to the rules described below under Pattern Matching. +If the shell option +nocasematch + +is enabled, the match is performed without regard to the case +of alphabetic characters. +The return value is 0 if the string matches (==) or does not match +(!=) the pattern, and 1 otherwise. +Any part of the pattern may be quoted to force it to be matched as a +string. +

+ + +An additional binary operator, =~, is available, with the same +precedence as == and !=. +When it is used, the string to the right of the operator is considered +an extended regular expression and matched accordingly (as in regex(3)). +The return value is 0 if the string matches +the pattern, and 1 otherwise. +If the regular expression is syntactically incorrect, the conditional +expression's return value is 2. +If the shell option +nocasematch + +is enabled, the match is performed without regard to the case +of alphabetic characters. +Substrings matched by parenthesized subexpressions within the regular +expression are saved in the array variable BASH_REMATCH. +The element of BASH_REMATCH with index 0 is the portion of the string +matching the entire regular expression. +The element of BASH_REMATCH with index n is the portion of the +string matching the nth parenthesized subexpression. +

+ + +Expressions may be combined using the following operators, listed +in decreasing order of precedence: +

+ + +

+ +
+
( expression ) + +
+Returns the value of expression. +This may be used to override the normal precedence of operators. +
! expression + +
+True if +expression + +is false. +
expression1 && expression2
+True if both +expression1 + +and +expression2 + +are true. +
expression1 || expression2 +
+ +True if either +expression1 + +or +expression2 + +is true. + +
+

+ +The && and +|| + +operators do not evaluate expression2 if the value of +expression1 is sufficient to determine the return value of +the entire conditional expression. +

+ +
for name [ in word ] ; do list ; done
+The list of words following in is expanded, generating a list +of items. +The variable name is set to each element of this list +in turn, and list is executed each time. +If the in word is omitted, the for command executes +list once for each positional parameter that is set (see +PARAMETERS + + +below). +The return status is the exit status of the last command that executes. +If the expansion of the items following in results in an empty +list, no commands are executed, and the return status is 0. +
for (( expr1 ; expr2 ; expr3 )) ; do list ; done
+First, the arithmetic expression expr1 is evaluated according +to the rules described below under +ARITHMETIC EVALUATION. + + +The arithmetic expression expr2 is then evaluated repeatedly +until it evaluates to zero. +Each time expr2 evaluates to a non-zero value, list is +executed and the arithmetic expression expr3 is evaluated. +If any expression is omitted, it behaves as if it evaluates to 1. +The return value is the exit status of the last command in list +that is executed, or false if any of the expressions is invalid. +
select name [ in word ] ; do list ; done
+The list of words following in is expanded, generating a list +of items. The set of expanded words is printed on the standard +error, each preceded by a number. If the in +word is omitted, the positional parameters are printed (see +PARAMETERS + + +below). The +PS3 + +prompt is then displayed and a line read from the standard input. +If the line consists of a number corresponding to one of +the displayed words, then the value of +name + +is set to that word. If the line is empty, the words and prompt +are displayed again. If EOF is read, the command completes. Any +other value read causes +name + +to be set to null. The line read is saved in the variable +REPLY. + +The +list + +is executed after each selection until a +break + +command is executed. +The exit status of +select + +is the exit status of the last command executed in +list, + +or zero if no commands were executed. +
case word in [ [(] pattern [ | pattern ] +
+A case command first expands word, and tries to match +it against each pattern in turn, using the same matching rules +as for pathname expansion (see +Pathname Expansion + +below). +The word is expanded using tilde +expansion, parameter and variable expansion, arithmetic substituion, +command substitution, process substitution and quote removal. +Each pattern examined is expanded using tilde +expansion, parameter and variable expansion, arithmetic substituion, +command substitution, and process substitution. +If the shell option +nocasematch + +is enabled, the match is performed without regard to the case +of alphabetic characters. +When a match is found, the +corresponding list is executed. After the first match, no +subsequent matches are attempted. The exit status is zero if no +pattern matches. Otherwise, it is the exit status of the +last command executed in list. +
if list; then list; [ elif list; then list; ] ... [ else list; ] fi
+The +if + +list + +is executed. If its exit status is zero, the +then list is executed. Otherwise, each elif +list is executed in turn, and if its exit status is zero, +the corresponding then list is executed and the +command completes. Otherwise, the else list is +executed, if present. The exit status is the exit status of the +last command executed, or zero if no condition tested true. +
while list; do list; done
+ +
until list; do list; done
+ +The while command continuously executes the do +list as long as the last command in list returns +an exit status of zero. The until command is identical +to the while command, except that the test is negated; +the +do + +list + +is executed as long as the last command in +list + +returns a non-zero exit status. +The exit status of the while and until commands +is the exit status +of the last do list command executed, or zero if +none was executed. +
+  +

Shell Function Definitions

+ +

+ +A shell function is an object that is called like a simple command and +executes a compound command with a new set of positional parameters. +Shell functions are declared as follows: +

+
[ function ] name () compound-command [redirection]
+This defines a function named name. +The reserved word function is optional. +If the function reserved word is supplied, the parentheses are optional. +The body of the function is the compound command +compound-command + +(see Compound Commands above). +That command is usually a list of commands between { and }, but +may be any command listed under Compound Commands above. +compound-command is executed whenever name is specified as the +name of a simple command. +Any redirections (see +REDIRECTION + + +below) specified when a function is defined are performed +when the function is executed. +The exit status of a function definition is zero unless a syntax error +occurs or a readonly function with the same name already exists. +When executed, the exit status of a function is the exit status of the +last command executed in the body. (See +FUNCTIONS + + +below.) +
+  +

COMMENTS

+ +In a non-interactive shell, or an interactive shell in which the +interactive_comments + +option to the +shopt + +builtin is enabled (see +SHELL BUILTIN COMMANDS + + +below), a word beginning with +# + +causes that word and all remaining characters on that line to +be ignored. An interactive shell without the +interactive_comments + +option enabled does not allow comments. The +interactive_comments + +option is on by default in interactive shells. +  +

QUOTING

+ +Quoting is used to remove the special meaning of certain +characters or words to the shell. Quoting can be used to +disable special treatment for special characters, to prevent +reserved words from being recognized as such, and to prevent +parameter expansion. +

+ +Each of the metacharacters listed above under +DEFINITIONS + + +has special meaning to the shell and must be quoted if it is to +represent itself. +

+ +When the command history expansion facilities are being used +(see +HISTORY EXPANSION + + +below), the +history expansion character, usually !, must be quoted +to prevent history expansion. +

+ +There are three quoting mechanisms: the +escape character, + +single quotes, and double quotes. +

+ +A non-quoted backslash (\) is the +escape character. + +It preserves the literal value of the next character that follows, +with the exception of <newline>. If a \<newline> pair +appears, and the backslash is not itself quoted, the \<newline> +is treated as a line continuation (that is, it is removed from the +input stream and effectively ignored). +

+ +Enclosing characters in single quotes preserves the literal value +of each character within the quotes. A single quote may not occur +between single quotes, even when preceded by a backslash. +

+ +Enclosing characters in double quotes preserves the literal value +of all characters within the quotes, with the exception of +$, + +`, + +\, + +and, when history expansion is enabled, +!. + +The characters +$ + +and +` + +retain their special meaning within double quotes. The backslash +retains its special meaning only when followed by one of the following +characters: +$, + +`, + +", +\, + +or +<newline>. + +A double quote may be quoted within double quotes by preceding it with +a backslash. +If enabled, history expansion will be performed unless an +! + +appearing in double quotes is escaped using a backslash. +The backslash preceding the +! + +is not removed. +

+ +The special parameters +* + +and +@ + +have special meaning when in double +quotes (see +PARAMETERS + + +below). +

+ +Words of the form $aqstringaq are treated specially. The +word expands to string, with backslash-escaped characters replaced +as specified by the ANSI C standard. Backslash escape sequences, if +present, are decoded as follows: +

+ +
+
\a + +
+alert (bell) +
\b + +
+backspace +
\e + +
+an escape character +

+ +A double-quoted string preceded by a dollar sign ($) will cause +the string to be translated according to the current locale. +If the current locale is C or POSIX, the dollar sign +is ignored. +If the string is translated and replaced, the replacement is +double-quoted. +  +

PARAMETERS

+ +A +parameter + +is an entity that stores values. +It can be a +name, + +a number, or one of the special characters listed below under +Special Parameters. + +A +variable + +is a parameter denoted by a +name. + +A variable has a value and zero or more attributes. +Attributes are assigned using the +declare + +builtin command (see +declare + +below in +SHELL BUILTIN COMMANDS). + + +

+ +A parameter is set if it has been assigned a value. The null string is +a valid value. Once a variable is set, it may be unset only by using +the +unset + +builtin command (see +SHELL BUILTIN COMMANDS + + +below). +

+ +A +variable + +may be assigned to by a statement of the form +

+

+ +name=[value] +

+ +

+ +If +value + +is not given, the variable is assigned the null string. All +values + +undergo tilde expansion, parameter and variable expansion, +command substitution, arithmetic expansion, and quote +removal (see +EXPANSION + + +below). If the variable has its +integer + +attribute set, then +value + +is evaluated as an arithmetic expression even if the $((...)) expansion is +not used (see +Arithmetic Expansion + +below). +Word splitting is not performed, with the exception +of "$@" as explained below under +Special Parameters. + +Pathname expansion is not performed. +Assignment statements may also appear as arguments to the +alias, + +declare, + +typeset, + +export, + +readonly, + +and +local + +builtin commands. +

+ +In the context where an assignment statement is assigning a value +to a shell variable or array index, the += operator can be used to +append to or add to the variable's previous value. +When += is applied to a variable for which the integer attribute has been +set, value is evaluated as an arithmetic expression and added to the +variable's current value, which is also evaluated. +When += is applied to an array variable using compound assignment (see +Arrays + +below), the +variable's value is not unset (as it is when using =), and new values are +appended to the array beginning at one greater than the array's maximum index. +When applied to a string-valued variable, value is expanded and +appended to the variable's value. +  +

Positional Parameters

+ +

+ +A +positional parameter + +is a parameter denoted by one or more +digits, other than the single digit 0. Positional parameters are +assigned from the shell's arguments when it is invoked, +and may be reassigned using the +set + +builtin command. Positional parameters may not be assigned to +with assignment statements. The positional parameters are +temporarily replaced when a shell function is executed (see +FUNCTIONS + + +below). +

+ +When a positional parameter consisting of more than a single +digit is expanded, it must be enclosed in braces (see +EXPANSION + + +below). +  +

Special Parameters

+ +

+ +The shell treats several parameters specially. These parameters may +only be referenced; assignment to them is not allowed. + +

+
* + +
+Expands to the positional parameters, starting from one. When the +expansion occurs within double quotes, it expands to a single word +with the value of each parameter separated by the first character +of the +IFS + + +special variable. That is, "$*" is equivalent +to "$1c$2c...", where +c + +is the first character of the value of the +IFS + + +variable. If +IFS + + +is unset, the parameters are separated by spaces. +If +IFS + + +is null, the parameters are joined without intervening separators. +
@ + +
+Expands to the positional parameters, starting from one. When the +expansion occurs within double quotes, each parameter expands to a +separate word. That is, "$@" is equivalent to +"$1" "$2" ... +If the double-quoted expansion occurs within a word, the expansion of +the first parameter is joined with the beginning part of the original +word, and the expansion of the last parameter is joined with the last +part of the original word. +When there are no positional parameters, "$@" and +$@ + +expand to nothing (i.e., they are removed). +
# + +
+Expands to the number of positional parameters in decimal. +
? + +
+Expands to the status of the most recently executed foreground +pipeline. +
- + +
+Expands to the current option flags as specified upon invocation, +by the +set + +builtin command, or those set by the shell itself +(such as the +-i + +option). +
$ + +
+Expands to the process ID of the shell. In a () subshell, it +expands to the process ID of the current shell, not the +subshell. +
! + +
+Expands to the process ID of the most recently executed background +(asynchronous) command. +
0 + +
+Expands to the name of the shell or shell script. This is set at +shell initialization. If +bash + +is invoked with a file of commands, +$0 + +is set to the name of that file. If +bash + +is started with the +-c + +option, then +$0 + +is set to the first argument after the string to be +executed, if one is present. Otherwise, it is set +to the file name used to invoke +bash, + +as given by argument zero. +
_ + +
+At shell startup, set to the absolute pathname used to invoke the +shell or shell script being executed as passed in the environment +or argument list. +Subsequently, expands to the last argument to the previous command, +after expansion. +Also set to the full pathname used to invoke each command executed +and placed in the environment exported to that command. +When checking mail, this parameter holds the name of the mail file +currently being checked. + +
+  +

Shell Variables

+ +

+ +The following variables are set by the shell: +

+ + +

+
BASH + +
+Expands to the full file name used to invoke this instance of +bash. + +
BASH_ARGC + +
+An array variable whose values are the number of parameters in each +frame of the current bash execution call stack. +The number of +parameters to the current subroutine (shell function or script executed +with . or source) is at the top of the stack. +When a subroutine is executed, the number of parameters passed is pushed onto +BASH_ARGC. +The shell sets BASH_ARGC only when in extended debugging mode +(see the description of the +extdebug + +option to the +shopt + +builtin below) +
BASH_ARGV + +
+An array variable containing all of the parameters in the current bash +execution call stack. The final parameter of the last subroutine call +is at the top of the stack; the first parameter of the initial call is +at the bottom. When a subroutine is executed, the parameters supplied +are pushed onto BASH_ARGV. +The shell sets BASH_ARGV only when in extended debugging mode +(see the description of the +extdebug + +option to the +shopt + +builtin below) +
BASH_COMMAND + +
+The command currently being executed or about to be executed, unless the +shell is executing a command as the result of a trap, +in which case it is the command executing at the time of the trap. +
BASH_EXECUTION_STRING + +
+The command argument to the -c invocation option. +
BASH_LINENO + +
+An array variable whose members are the line numbers in source files +corresponding to each member of FUNCNAME. +${BASH_LINENO[$i]} is the line number in the source +file where ${FUNCNAME[$ifP]} was called. +The corresponding source file name is ${BASH_SOURCE[$i]}. +Use LINENO to obtain the current line number. +
BASH_REMATCH + +
+An array variable whose members are assigned by the =~ binary +operator to the [[ conditional command. +The element with index 0 is the portion of the string +matching the entire regular expression. +The element with index n is the portion of the +string matching the nth parenthesized subexpression. +This variable is read-only. +
BASH_SOURCE + +
+An array variable whose members are the source filenames corresponding +to the elements in the FUNCNAME array variable. +
BASH_SUBSHELL + +
+Incremented by one each time a subshell or subshell environment is spawned. +The initial value is 0. +
BASH_VERSINFO + +
+A readonly array variable whose members hold version information for +this instance of +bash. + +The values assigned to the array members are as follows: +

+

+ +
+
BASH_VERSINFO[0] + +
+The major version number (the release). +
BASH_VERSINFO[1] + +
+The minor version number (the version). +
BASH_VERSINFO[2] + +
+The patch level. +
BASH_VERSINFO[3] + +
+The build version. +
BASH_VERSINFO[4] + +
+The release status (e.g., beta1). +
BASH_VERSINFO[5] + +
+The value of MACHTYPE. + +
+ +
BASH_VERSION + +
+Expands to a string describing the version of this instance of +bash. + +
COMP_CWORD + +
+An index into ${COMP_WORDS} of the word containing the current +cursor position. +This variable is available only in shell functions invoked by the +programmable completion facilities (see Programmable Completion +below). +
COMP_LINE + +
+The current command line. +This variable is available only in shell functions and external +commands invoked by the +programmable completion facilities (see Programmable Completion +below). +
COMP_POINT + +
+The index of the current cursor position relative to the beginning of +the current command. +If the current cursor position is at the end of the current command, +the value of this variable is equal to ${#COMP_LINE}. +This variable is available only in shell functions and external +commands invoked by the +programmable completion facilities (see Programmable Completion +below). +
COMP_WORDBREAKS + +
+The set of characters that the Readline library treats as word +separators when performing word completion. +If +COMP_WORDBREAKS + + +is unset, it loses its special properties, even if it is +subsequently reset. +
COMP_WORDS + +
+An array variable (see Arrays below) consisting of the individual +words in the current command line. +This variable is available only in shell functions invoked by the +programmable completion facilities (see Programmable Completion +below). +
DIRSTACK + +
+An array variable (see +Arrays + +below) containing the current contents of the directory stack. +Directories appear in the stack in the order they are displayed by the +dirs + +builtin. +Assigning to members of this array variable may be used to modify +directories already in the stack, but the +pushd + +and +popd + +builtins must be used to add and remove directories. +Assignment to this variable will not change the current directory. +If +DIRSTACK + + +is unset, it loses its special properties, even if it is +subsequently reset. +
EUID + +
+Expands to the effective user ID of the current user, initialized at +shell startup. This variable is readonly. +
FUNCNAME + +
+An array variable containing the names of all shell functions +currently in the execution call stack. +The element with index 0 is the name of any currently-executing +shell function. +The bottom-most element is "main". +This variable exists only when a shell function is executing. +Assignments to +FUNCNAME + + +have no effect and return an error status. +If +FUNCNAME + + +is unset, it loses its special properties, even if it is +subsequently reset. +
GROUPS + +
+An array variable containing the list of groups of which the current +user is a member. +Assignments to +GROUPS + + +have no effect and return an error status. +If +GROUPS + + +is unset, it loses its special properties, even if it is +subsequently reset. +
HISTCMD + +
+The history number, or index in the history list, of the current +command. +If +HISTCMD + + +is unset, it loses its special properties, even if it is +subsequently reset. +
HOSTNAME + +
+Automatically set to the name of the current host. +
HOSTTYPE + +
+Automatically set to a string that uniquely +describes the type of machine on which +bash + +is executing. +The default is system-dependent. +
LINENO + +
+Each time this parameter is referenced, the shell substitutes +a decimal number representing the current sequential line number +(starting with 1) within a script or function. When not in a +script or function, the value substituted is not guaranteed to +be meaningful. +If +LINENO + + +is unset, it loses its special properties, even if it is +subsequently reset. +
MACHTYPE + +
+Automatically set to a string that fully describes the system +type on which +bash + +is executing, in the standard GNU cpu-company-system format. +The default is system-dependent. +
OLDPWD + +
+The previous working directory as set by the +cd + +command. +
OPTARG + +
+The value of the last option argument processed by the +getopts + +builtin command (see +SHELL BUILTIN COMMANDS + + +below). +
OPTIND + +
+The index of the next argument to be processed by the +getopts + +builtin command (see +SHELL BUILTIN COMMANDS + + +below). +
OSTYPE + +
+Automatically set to a string that +describes the operating system on which +bash + +is executing. +The default is system-dependent. +
PIPESTATUS + +
+An array variable (see +Arrays + +below) containing a list of exit status values from the processes +in the most-recently-executed foreground pipeline (which may +contain only a single command). +
PPID + +
+The process ID of the shell's parent. This variable is readonly. +
PWD + +
+The current working directory as set by the +cd + +command. +
RANDOM + +
+Each time this parameter is referenced, a random integer between +0 and 32767 is +generated. The sequence of random numbers may be initialized by assigning +a value to +RANDOM. + + +If +RANDOM + + +is unset, it loses its special properties, even if it is +subsequently reset. +
REPLY + +
+Set to the line of input read by the +read + +builtin command when no arguments are supplied. +
SECONDS + +
+Each time this parameter is +referenced, the number of seconds since shell invocation is returned. If a +value is assigned to +SECONDS, + + +the value returned upon subsequent +references is +the number of seconds since the assignment plus the value assigned. +If +SECONDS + + +is unset, it loses its special properties, even if it is +subsequently reset. +
SHELLOPTS + +
+A colon-separated list of enabled shell options. Each word in +the list is a valid argument for the +-o + +option to the +set + +builtin command (see +SHELL BUILTIN COMMANDS + + +below). The options appearing in +SHELLOPTS + + +are those reported as +on + +by set -o. +If this variable is in the environment when +bash + +starts up, each shell option in the list will be enabled before +reading any startup files. +This variable is read-only. +
SHLVL + +
+Incremented by one each time an instance of +bash + +is started. +
UID + +
+Expands to the user ID of the current user, initialized at shell startup. +This variable is readonly. + +
+

+ +The following variables are used by the shell. In some cases, +bash + +assigns a default value to a variable; these cases are noted +below. +

+ + +

+
BASH_ENV + +
+If this parameter is set when bash is executing a shell script, +its value is interpreted as a filename containing commands to +initialize the shell, as in +~/.bashrc. + +The value of +BASH_ENV + + +is subjected to parameter expansion, command substitution, and arithmetic +expansion before being interpreted as a file name. +PATH + + +is not used to search for the resultant file name. +
CDPATH + +
+The search path for the +cd + +command. +This is a colon-separated list of directories in which the shell looks +for destination directories specified by the +cd + +command. +A sample value is +".:~:/usr". + +
COLUMNS + +
+Used by the select builtin command to determine the terminal width +when printing selection lists. Automatically set upon receipt of a SIGWINCH. +
COMPREPLY + +
+An array variable from which bash reads the possible completions +generated by a shell function invoked by the programmable completion +facility (see Programmable Completion below). +
EMACS + +
+If bash finds this variable in the environment when the shell starts +with value +t, + +it assumes that the shell is running in an emacs shell buffer and disables +line editing. +
FCEDIT + +
+The default editor for the +fc + +builtin command. +
FIGNORE + +
+A colon-separated list of suffixes to ignore when performing +filename completion (see +READLINE + + +below). +A filename whose suffix matches one of the entries in +FIGNORE + + +is excluded from the list of matched filenames. +A sample value is +".o:~". + +
GLOBIGNORE + +
+A colon-separated list of patterns defining the set of filenames to +be ignored by pathname expansion. +If a filename matched by a pathname expansion pattern also matches one +of the patterns in +GLOBIGNORE, + + +it is removed from the list of matches. +
HISTCONTROL + +
+A colon-separated list of values controlling how commands are saved on +the history list. +If the list of values includes +ignorespace, + +lines which begin with a +space + +character are not saved in the history list. +A value of +ignoredups + +causes lines matching the previous history entry to not be saved. +A value of +ignoreboth + +is shorthand for ignorespace and ignoredups. +A value of +erasedups + +causes all previous lines matching the current line to be removed from +the history list before that line is saved. +Any value not in the above list is ignored. +If HISTCONTROL is unset, or does not include a valid value, +all lines read by the shell parser are saved on the history list, +subject to the value of +HISTIGNORE. + +The second and subsequent lines of a multi-line compound command are +not tested, and are added to the history regardless of the value of +HISTCONTROL. + +
HISTFILE + +
+The name of the file in which command history is saved (see +HISTORY + + +below). The default value is ~/.bash_history. If unset, the +command history is not saved when an interactive shell exits. +
HISTFILESIZE + +
+The maximum number of lines contained in the history file. When this +variable is assigned a value, the history file is truncated, if +necessary, to contain no more than that number of lines. The default +value is 500. The history file is also truncated to this size after +writing it when an interactive shell exits. +
HISTIGNORE + +
+A colon-separated list of patterns used to decide which command lines +should be saved on the history list. Each pattern is anchored at the +beginning of the line and must match the complete line (no implicit +`*' is appended). Each pattern is tested against the line +after the checks specified by +HISTCONTROL + +are applied. +In addition to the normal shell pattern matching characters, `&' +matches the previous history line. `&' may be escaped using a +backslash; the backslash is removed before attempting a match. +The second and subsequent lines of a multi-line compound command are +not tested, and are added to the history regardless of the value of +HISTIGNORE. + +
HISTSIZE + +
+The number of commands to remember in the command history (see +HISTORY + + +below). The default value is 500. +
HISTTIMEFORMAT + +
+If this variable is set and not null, its value is used as a format string +for strftime(3) to print the time stamp associated with each history +entry displayed by the history builtin. +If this variable is set, time stamps are written to the history file so +they may be preserved across shell sessions. +
HOME + +
+The home directory of the current user; the default argument for the +cd builtin command. +The value of this variable is also used when performing tilde expansion. +
HOSTFILE + +
+Contains the name of a file in the same format as + +/etc/hosts + +that should be read when the shell needs to complete a +hostname. +The list of possible hostname completions may be changed while the +shell is running; +the next time hostname completion is attempted after the +value is changed, +bash + +adds the contents of the new file to the existing list. +If +HOSTFILE + + +is set, but has no value, bash attempts to read + +/etc/hosts + +to obtain the list of possible hostname completions. +When +HOSTFILE + + +is unset, the hostname list is cleared. +
IFS + +
+The +Internal Field Separator + +that is used +for word splitting after expansion and to +split lines into words with the +read + +builtin command. The default value is +``<space><tab><newline>''. +
IGNOREEOF + +
+Controls the +action of an interactive shell on receipt of an +EOF + + +character as the sole input. If set, the value is the number of +consecutive +EOF + + +characters which must be +typed as the first characters on an input line before +bash + +exits. If the variable exists but does not have a numeric value, or +has no value, the default value is 10. If it does not exist, +EOF + + +signifies the end of input to the shell. +
INPUTRC + +
+The filename for the +readline + +startup file, overriding the default of + +~/.inputrc + +(see +READLINE + + +below). +
LANG + +
+Used to determine the locale category for any category not specifically +selected with a variable starting with LC_. +
LC_ALL + +
+This variable overrides the value of LANG and any other +LC_ variable specifying a locale category. +
LC_COLLATE + +
+This variable determines the collation order used when sorting the +results of pathname expansion, and determines the behavior of range +expressions, equivalence classes, and collating sequences within +pathname expansion and pattern matching. +
LC_CTYPE + +
+This variable determines the interpretation of characters and the +behavior of character classes within pathname expansion and pattern +matching. +
LC_MESSAGES + +
+This variable determines the locale used to translate double-quoted +strings preceded by a $. +
LC_NUMERIC + +
+This variable determines the locale category used for number formatting. +
LINES + +
+Used by the select builtin command to determine the column length +for printing selection lists. Automatically set upon receipt of a SIGWINCH. +
MAIL + +
+If this parameter is set to a file name and the +MAILPATH + + +variable is not set, +bash + +informs the user of the arrival of mail in the specified file. +
MAILCHECK + +
+Specifies how +often (in seconds) +bash + +checks for mail. The default is 60 seconds. When it is time to check +for mail, the shell does so before displaying the primary prompt. +If this variable is unset, or set to a value that is not a number +greater than or equal to zero, the shell disables mail checking. +
MAILPATH + +
+A colon-separated list of file names to be checked for mail. +The message to be printed when mail arrives in a particular file +may be specified by separating the file name from the message with a `?'. +When used in the text of the message, $_ expands to the name of +the current mailfile. +Example: +
+

+ +MAILPATH=aq/var/mail/bfox?"You have mail":~/shell-mail?"$_ has mail!"aq +

+ +Bash + +supplies a default value for this variable, but the location of the user +mail files that it uses is system dependent (e.g., /var/mail/$USER). +

+ +
OPTERR + +
+If set to the value 1, +bash + +displays error messages generated by the +getopts + +builtin command (see +SHELL BUILTIN COMMANDS + + +below). +OPTERR + + +is initialized to 1 each time the shell is invoked or a shell +script is executed. +
PATH + +
+The search path for commands. It +is a colon-separated list of directories in which +the shell looks for commands (see +COMMAND EXECUTION + + +below). +A zero-length (null) directory name in the value of PATH indicates the +current directory. +A null directory name may appear as two adjacent colons, or as an initial +or trailing colon. +The default path is system-dependent, +and is set by the administrator who installs +bash. + +A common value is +/usr/gnu/bin:/usr/local/bin:/usr/ucb:/bin:/usr/bin. + +
POSIXLY_CORRECT + +
+If this variable is in the environment when bash starts, the shell +enters posix mode before reading the startup files, as if the +--posix + +invocation option had been supplied. If it is set while the shell is +running, bash enables posix mode, as if the command +set -o posix + +had been executed. +
PROMPT_COMMAND + +
+If set, the value is executed as a command prior to issuing each primary +prompt. +
PS1 + +
+The value of this parameter is expanded (see +PROMPTING + + +below) and used as the primary prompt string. The default value is +``\s-\v\$ ''. +
PS2 + +
+The value of this parameter is expanded as with +PS1 + +and used as the secondary prompt string. The default is +``> ''. +
PS3 + +
+The value of this parameter is used as the prompt for the +select + +command (see +SHELL GRAMMAR + + +above). +
PS4 + +
+The value of this parameter is expanded as with +PS1 + +and the value is printed before each command +bash + +displays during an execution trace. The first character of +PS4 + + +is replicated multiple times, as necessary, to indicate multiple +levels of indirection. The default is ``+ ''. +
SHELL + +
+The full pathname to the shell is kept in this environment variable. +If it is not set when the shell starts, +bash + +assigns to it the full pathname of the current user's login shell. +
TIMEFORMAT + +
+The value of this parameter is used as a format string specifying +how the timing information for pipelines prefixed with the +time + +reserved word should be displayed. +The % character introduces an escape sequence that is +expanded to a time value or other information. +The escape sequences and their meanings are as follows; the +braces denote optional portions. +

+

+ +
+
%% + +
+A literal %. +
%[p][l]R + +
+The elapsed time in seconds. +
%[p][l]U + +
+The number of CPU seconds spent in user mode. +
%[p][l]S + +
+The number of CPU seconds spent in system mode. +
%P + +
+The CPU percentage, computed as (%U + %S) / %R. + +
+ +
+The optional p is a digit specifying the precision, +the number of fractional digits after a decimal point. +A value of 0 causes no decimal point or fraction to be output. +At most three places after the decimal point may be specified; +values of p greater than 3 are changed to 3. +If p is not specified, the value 3 is used. +
+The optional l specifies a longer format, including +minutes, of the form MMmSS.FFs. +The value of p determines whether or not the fraction is +included. +
+If this variable is not set, bash acts as if it had the +value $aq\nreal\t%3lR\nuser\t%3lU\nsys %3lSaq. +If the value is null, no timing information is displayed. +A trailing newline is added when the format string is displayed. +
TMOUT + +
+If set to a value greater than zero, TMOUT is treated as the +default timeout for the read builtin. +The select command terminates if input does not arrive +after TMOUT seconds when input is coming from a terminal. +In an interactive shell, the value is interpreted as the +number of seconds to wait for input after issuing the primary prompt. +Bash + +terminates after waiting for that number of seconds if input does +not arrive. +
TMPDIR + +
+If set, Bash uses its value as the name of a directory in which +Bash creates temporary files for the shell's use. +
auto_resume + +
+This variable controls how the shell interacts with the user and +job control. If this variable is set, single word simple +commands without redirections are treated as candidates for resumption +of an existing stopped job. There is no ambiguity allowed; if there is +more than one job beginning with the string typed, the job most recently +accessed is selected. The +name + +of a stopped job, in this context, is the command line used to +start it. +If set to the value +exact, + +the string supplied must match the name of a stopped job exactly; +if set to +substring, + +the string supplied needs to match a substring of the name of a +stopped job. The +substring + +value provides functionality analogous to the +%? + +job identifier (see +JOB CONTROL + + +below). If set to any other value, the supplied string must +be a prefix of a stopped job's name; this provides functionality +analogous to the %string job identifier. +
histchars + +
+The two or three characters which control history expansion +and tokenization (see +HISTORY EXPANSION + + +below). The first character is the history expansion character, +the character which signals the start of a history +expansion, normally `!'. +The second character is the quick substitution +character, which is used as shorthand for re-running the previous +command entered, substituting one string for another in the command. +The default is `^'. +The optional third character is the character +which indicates that the remainder of the line is a comment when found +as the first character of a word, normally `#'. The history +comment character causes history substitution to be skipped for the +remaining words on the line. It does not necessarily cause the shell +parser to treat the rest of the line as a comment. + +
+  +

Arrays

+ +Bash + +provides one-dimensional array variables. Any variable may be used as +an array; the +declare + +builtin will explicitly declare an array. There is no maximum +limit on the size of an array, nor any requirement that members +be indexed or assigned contiguously. Arrays are indexed using +integers and are zero-based. +

+ +An array is created automatically if any variable is assigned to using +the syntax name[subscript]=value. The +subscript + +is treated as an arithmetic expression that must evaluate to a number +greater than or equal to zero. To explicitly declare an array, use +declare -a name + +(see +SHELL BUILTIN COMMANDS + + +below). +declare -a name[subscript] + +is also accepted; the subscript is ignored. Attributes may be +specified for an array variable using the +declare + +and +readonly + +builtins. Each attribute applies to all members of an array. +

+ +Arrays are assigned to using compound assignments of the form +name=(value1 ... valuen), where each +value is of the form [subscript]=string. Only +string is required. If +the optional brackets and subscript are supplied, that index is assigned to; +otherwise the index of the element assigned is the last index assigned +to by the statement plus one. Indexing starts at zero. +This syntax is also accepted by the +declare + +builtin. Individual array elements may be assigned to using the +name[subscript]=value syntax introduced above. +

+ +Any element of an array may be referenced using +${name[subscript]}. The braces are required to avoid +conflicts with pathname expansion. If +subscript is @ or *, the word expands to +all members of name. These subscripts differ only when the +word appears within double quotes. If the word is double-quoted, +${name[*]} expands to a single +word with the value of each array member separated by the first +character of the +IFS + + +special variable, and ${name[@]} expands each element of +name to a separate word. When there are no array members, +${name[@]} expands to nothing. +If the double-quoted expansion occurs within a word, the expansion of +the first parameter is joined with the beginning part of the original +word, and the expansion of the last parameter is joined with the last +part of the original word. +This is analogous to the expansion +of the special parameters * and @ (see +Special Parameters + +above). ${#name[subscript]} expands to the length of +${name[subscript]}. If subscript is * or +@, the expansion is the number of elements in the array. +Referencing an array variable without a subscript is equivalent to +referencing element zero. +

+ +The +unset + +builtin is used to destroy arrays. unset name[subscript] +destroys the array element at index subscript. +Care must be taken to avoid unwanted side effects caused by filename +generation. +unset name, where name is an array, or +unset name[subscript], where +subscript is * or @, removes the entire array. +

+ +The +declare, + +local, + +and +readonly + +builtins each accept a +-a + +option to specify an array. The +read + +builtin accepts a +-a + +option to assign a list of words read from the standard input +to an array. The +set + +and +declare + +builtins display array values in a way that allows them to be +reused as assignments. +  +

EXPANSION

+ +Expansion is performed on the command line after it has been split into +words. There are seven kinds of expansion performed: +brace expansion, + +tilde expansion, + +parameter and variable expansion, + +command substitution, + +arithmetic expansion, + +word splitting, + +and +pathname expansion. + +

+ +The order of expansions is: brace expansion, tilde expansion, +parameter, variable and arithmetic expansion and +command substitution +(done in a left-to-right fashion), word splitting, and pathname +expansion. +

+ +On systems that can support it, there is an additional expansion +available: process substitution. +

+ +Only brace expansion, word splitting, and pathname expansion +can change the number of words of the expansion; other expansions +expand a single word to a single word. +The only exceptions to this are the expansions of +"$@" and "${name[@]}" +as explained above (see +PARAMETERS). + + +  +

Brace Expansion

+ +

+ +Brace expansion + +is a mechanism by which arbitrary strings +may be generated. This mechanism is similar to +pathname expansion, but the filenames generated +need not exist. Patterns to be brace expanded take +the form of an optional +preamble, + +followed by either a series of comma-separated strings or +a sequence expression between a pair of braces, followed by +an optional +postscript. + +The preamble is prefixed to each string contained +within the braces, and the postscript is then appended +to each resulting string, expanding left to right. +

+ +Brace expansions may be nested. The results of each expanded +string are not sorted; left to right order is preserved. +For example, a{d,c,b}e expands into `ade ace abe'. +

+ +A sequence expression takes the form {x..y}, +where x and y are either integers or single characters. +When integers are supplied, the expression expands to each number between +x and y, inclusive. +When characters are supplied, the expression expands to each character +lexicographically between x and y, inclusive. Note that +both x and y must be of the same type. +

+ +Brace expansion is performed before any other expansions, +and any characters special to other expansions are preserved +in the result. It is strictly textual. +Bash + +does not apply any syntactic interpretation to the context of the +expansion or the text between the braces. +

+ +A correctly-formed brace expansion must contain unquoted opening +and closing braces, and at least one unquoted comma or a valid +sequence expression. +Any incorrectly formed brace expansion is left unchanged. +A { or , may be quoted with a backslash to prevent its +being considered part of a brace expression. +To avoid conflicts with parameter expansion, the string ${ +is not considered eligible for brace expansion. +

+ +This construct is typically used as shorthand when the common +prefix of the strings to be generated is longer than in the +above example: +

+

+ +mkdir /usr/local/src/bash/{old,new,dist,bugs} +

+ +or +
+chown root /usr/{ucb/{ex,edit},lib/{ex?.?*,how_ex}} +
+ +

+ +Brace expansion introduces a slight incompatibility with +historical versions of +sh. + +sh + +does not treat opening or closing braces specially when they +appear as part of a word, and preserves them in the output. +Bash + +removes braces from words as a consequence of brace +expansion. For example, a word entered to +sh + +as file{1,2} +appears identically in the output. The same word is +output as +file1 file2 + +after expansion by +bash. + +If strict compatibility with +sh + +is desired, start +bash + +with the ++B + +option or disable brace expansion with the ++B + +option to the +set + +command (see +SHELL BUILTIN COMMANDS + + +below). +  +

Tilde Expansion

+ +

+ +If a word begins with an unquoted tilde character (`~'), all of +the characters preceding the first unquoted slash (or all characters, +if there is no unquoted slash) are considered a tilde-prefix. +If none of the characters in the tilde-prefix are quoted, the +characters in the tilde-prefix following the tilde are treated as a +possible login name. +If this login name is the null string, the tilde is replaced with the +value of the shell parameter +HOME. + + +If +HOME + + +is unset, the home directory of the user executing the shell is +substituted instead. +Otherwise, the tilde-prefix is replaced with the home directory +associated with the specified login name. +

+ +If the tilde-prefix is a `~+', the value of the shell variable +PWD + + +replaces the tilde-prefix. +If the tilde-prefix is a `~-', the value of the shell variable +OLDPWD, + + +if it is set, is substituted. +If the characters following the tilde in the tilde-prefix consist +of a number N, optionally prefixed +by a `+' or a `-', the tilde-prefix is replaced with the corresponding +element from the directory stack, as it would be displayed by the +dirs + +builtin invoked with the tilde-prefix as an argument. +If the characters following the tilde in the tilde-prefix consist of a +number without a leading `+' or `-', `+' is assumed. +

+ +If the login name is invalid, or the tilde expansion fails, the word +is unchanged. +

+ +Each variable assignment is checked for unquoted tilde-prefixes immediately +following a +: + +or the first +=. + +In these cases, tilde expansion is also performed. +Consequently, one may use file names with tildes in assignments to +PATH, + + +MAILPATH, + + +and +CDPATH, + + +and the shell assigns the expanded value. +  +

Parameter Expansion

+ +

+ +The `$' character introduces parameter expansion, +command substitution, or arithmetic expansion. The parameter name +or symbol to be expanded may be enclosed in braces, which +are optional but serve to protect the variable to be expanded from +characters immediately following it which could be +interpreted as part of the name. +

+ +When braces are used, the matching ending brace is the first `}' +not escaped by a backslash or within a quoted string, and not within an +embedded arithmetic expansion, command substitution, or parameter +expansion. +

+ + +

+
${parameter}
+The value of parameter is substituted. The braces are required +when +parameter + +is a positional parameter with more than one digit, +or when +parameter + +is followed by a character which is not to be +interpreted as part of its name. + +
+

+ +If the first character of parameter is an exclamation point, +a level of variable indirection is introduced. +Bash uses the value of the variable formed from the rest of +parameter as the name of the variable; this variable is then +expanded and that value is used in the rest of the substitution, rather +than the value of parameter itself. +This is known as indirect expansion. +The exceptions to this are the expansions of ${!prefix*} and +${!name[@]} described below. +The exclamation point must immediately follow the left brace in order to +introduce indirection. +

+ +In each of the cases below, word is subject to tilde expansion, +parameter expansion, command substitution, and arithmetic expansion. +When not performing substring expansion, bash tests for a parameter +that is unset or null; omitting the colon results in a test only for a +parameter that is unset. +

+ + +

+
${parameter:-word}
+Use Default Values. If +parameter + +is unset or null, the expansion of +word + +is substituted. Otherwise, the value of +parameter + +is substituted. +
${parameter:=word}
+Assign Default Values. +If +parameter + +is unset or null, the expansion of +word + +is assigned to +parameter. + +The value of +parameter + +is then substituted. Positional parameters and special parameters may +not be assigned to in this way. +
${parameter:?word}
+Display Error if Null or Unset. +If +parameter + +is null or unset, the expansion of word (or a message to that effect +if +word + +is not present) is written to the standard error and the shell, if it +is not interactive, exits. Otherwise, the value of parameter is +substituted. +
${parameter:+word}
+Use Alternate Value. +If +parameter + +is null or unset, nothing is substituted, otherwise the expansion of +word + +is substituted. +
${parameter:offset}
+ +
${parameter:offset:length}
+ +Substring Expansion. +Expands to up to length characters of parameter +starting at the character specified by offset. +If length is omitted, expands to the substring of +parameter starting at the character specified by offset. +length and offset are arithmetic expressions (see +ARITHMETIC EVALUATION + + +below). +length must evaluate to a number greater than or equal to zero. +If offset evaluates to a number less than zero, the value +is used as an offset from the end of the value of parameter. +If parameter is @, the result is length positional +parameters beginning at offset. +If parameter is an array name indexed by @ or *, +the result is the length +members of the array beginning with ${parameter[offset]}. +A negative offset is taken relative to one greater than the maximum +index of the specified array. +Note that a negative offset must be separated from the colon by at least +one space to avoid being confused with the :- expansion. +Substring indexing is zero-based unless the positional parameters +are used, in which case the indexing starts at 1. +
${!prefix*}
+ +
${!prefix@}
+ +Expands to the names of variables whose names begin with prefix, +separated by the first character of the +IFS + + +special variable. +
${!name[@]}
+ +
${!name[*]}
+ +If name is an array variable, expands to the list of array indices +(keys) assigned in name. +If name is not an array, expands to 0 if name is set and null +otherwise. +When @ is used and the expansion appears within double quotes, each +key expands to a separate word. +
${#parameter}
+The length in characters of the value of parameter is substituted. +If +parameter + +is +* + +or +@, + +the value substituted is the number of positional parameters. +If +parameter + +is an array name subscripted by +* + +or +@, + +the value substituted is the number of elements in the array. +
${parameter#word}
+ +
${parameter##word}
+ +The +word + +is expanded to produce a pattern just as in pathname +expansion. If the pattern matches the beginning of +the value of +parameter, + +then the result of the expansion is the expanded value of +parameter + +with the shortest matching pattern (the ``#'' case) or the +longest matching pattern (the ``##'' case) deleted. +If +parameter + +is +@ + +or +*, + +the pattern removal operation is applied to each positional +parameter in turn, and the expansion is the resultant list. +If +parameter + +is an array variable subscripted with +@ + +or +*, + +the pattern removal operation is applied to each member of the +array in turn, and the expansion is the resultant list. +
${parameter%word}
+ +
${parameter%%word}
+ +The word is expanded to produce a pattern just as in +pathname expansion. +If the pattern matches a trailing portion of the expanded value of +parameter, + +then the result of the expansion is the expanded value of +parameter + +with the shortest matching pattern (the ``%'' case) or the +longest matching pattern (the ``%%'' case) deleted. +If +parameter + +is +@ + +or +*, + +the pattern removal operation is applied to each positional +parameter in turn, and the expansion is the resultant list. +If +parameter + +is an array variable subscripted with +@ + +or +*, + +the pattern removal operation is applied to each member of the +array in turn, and the expansion is the resultant list. +
${parameter/pattern/string}
+The pattern is expanded to produce a pattern just as in +pathname expansion. +Parameter is expanded and the longest match of pattern +against its value is replaced with string. +If Ipattern begins with /, all matches of pattern are +replaced with string. Normally only the first match is replaced. +If pattern begins with #, it must match at the beginning +of the expanded value of parameter. +If pattern begins with %, it must match at the end +of the expanded value of parameter. +If string is null, matches of pattern are deleted +and the / following pattern may be omitted. +If +parameter + +is +@ + +or +*, + +the substitution operation is applied to each positional +parameter in turn, and the expansion is the resultant list. +If +parameter + +is an array variable subscripted with +@ + +or +*, + +the substitution operation is applied to each member of the +array in turn, and the expansion is the resultant list. +
+  +

Command Substitution

+ +

+ +Command substitution allows the output of a command to replace +the command name. There are two forms: +

+ +

+

+ +$(command) +

+ +or +
+`command` +
+ +

+ +Bash + +performs the expansion by executing command and +replacing the command substitution with the standard output of the +command, with any trailing newlines deleted. +Embedded newlines are not deleted, but they may be removed during +word splitting. +The command substitution $(cat file) can be replaced by +the equivalent but faster $(< file). +

+ +When the old-style backquote form of substitution is used, +backslash retains its literal meaning except when followed by +$, + +`, + +or +\. + +The first backquote not preceded by a backslash terminates the +command substitution. +When using the $(command) form, all characters between the +parentheses make up the command; none are treated specially. +

+ +Command substitutions may be nested. To nest when using the backquoted form, +escape the inner backquotes with backslashes. +

+ +If the substitution appears within double quotes, word splitting and +pathname expansion are not performed on the results. +  +

Arithmetic Expansion

+ +

+ +Arithmetic expansion allows the evaluation of an arithmetic expression +and the substitution of the result. The format for arithmetic expansion is: +

+

+ +$((expression)) +

+ +

+ +The +expression + +is treated as if it were within double quotes, but a double quote +inside the parentheses is not treated specially. +All tokens in the expression undergo parameter expansion, string +expansion, command substitution, and quote removal. +Arithmetic expansions may be nested. +

+ +The evaluation is performed according to the rules listed below under +ARITHMETIC EVALUATION. + + +If +expression + +is invalid, +bash + +prints a message indicating failure and no substitution occurs. +  +

Process Substitution

+ +

+ +Process substitution is supported on systems that support named +pipes (FIFOs) or the /dev/fd method of naming open files. +It takes the form of +<(list) +or +>(list). +The process list is run with its input or output connected to a +FIFO or some file in /dev/fd. The name of this file is +passed as an argument to the current command as the result of the +expansion. If the >(list) form is used, writing to +the file will provide input for list. If the +<(list) form is used, the file passed as an +argument should be read to obtain the output of list. +

+ +When available, process substitution is performed +simultaneously with parameter and variable expansion, +command substitution, +and arithmetic expansion. +  +

Word Splitting

+ +

+ +The shell scans the results of +parameter expansion, +command substitution, +and +arithmetic expansion +that did not occur within double quotes for +word splitting. + +

+ +The shell treats each character of +IFS + + +as a delimiter, and splits the results of the other +expansions into words on these characters. If +IFS + + +is unset, or its +value is exactly +<space><tab><newline>, + +the default, then +any sequence of +IFS + + +characters serves to delimit words. If +IFS + + +has a value other than the default, then sequences of +the whitespace characters +space + +and +tab + +are ignored at the beginning and end of the +word, as long as the whitespace character is in the +value of +IFS + + +(an +IFS + + +whitespace character). +Any character in +IFS + + +that is not +IFS + + +whitespace, along with any adjacent +IFS + + +whitespace characters, delimits a field. +A sequence of +IFS + + +whitespace characters is also treated as a delimiter. +If the value of +IFS + + +is null, no word splitting occurs. +

+ +Explicit null arguments ("" or aqaq) are retained. +Unquoted implicit null arguments, resulting from the expansion of +parameters that have no values, are removed. +If a parameter with no value is expanded within double quotes, a +null argument results and is retained. +

+ +Note that if no expansion occurs, no splitting +is performed. +  +

Pathname Expansion

+ +

+ +After word splitting, +unless the +-f + +option has been set, +bash + +scans each word for the characters +*, + +?, + +and +[. + +If one of these characters appears, then the word is +regarded as a +pattern, + +and replaced with an alphabetically sorted list of +file names matching the pattern. +If no matching file names are found, +and the shell option +nullglob + +is disabled, the word is left unchanged. +If the +nullglob + +option is set, and no matches are found, +the word is removed. +If the +failglob + +shell option is set, and no matches are found, an error message +is printed and the command is not executed. +If the shell option +nocaseglob + +is enabled, the match is performed without regard to the case +of alphabetic characters. +When a pattern is used for pathname expansion, +the character +``.'' + +at the start of a name or immediately following a slash +must be matched explicitly, unless the shell option +dotglob + +is set. +When matching a pathname, the slash character must always be +matched explicitly. +In other cases, the +``.'' + +character is not treated specially. +See the description of +shopt + +below under +SHELL BUILTIN COMMANDS + + +for a description of the +nocaseglob, + +nullglob, + +failglob, + +and +dotglob + +shell options. +

+ +The +GLOBIGNORE + + +shell variable may be used to restrict the set of file names matching a +pattern. + +If +GLOBIGNORE + + +is set, each matching file name that also matches one of the patterns in +GLOBIGNORE + + +is removed from the list of matches. +The file names +``.'' + +and +``..'' + +are always ignored when +GLOBIGNORE + + +is set and not null. However, setting +GLOBIGNORE + + +to a non-null value has the effect of enabling the +dotglob + +shell option, so all other file names beginning with a +``.'' + +will match. +To get the old behavior of ignoring file names beginning with a +``.'', + +make +``.*'' + +one of the patterns in +GLOBIGNORE. + + +The +dotglob + +option is disabled when +GLOBIGNORE + + +is unset. +

+ +Pattern Matching +

+ +Any character that appears in a pattern, other than the special pattern +characters described below, matches itself. The NUL character may not +occur in a pattern. A backslash escapes the following character; the +escaping backslash is discarded when matching. +The special pattern characters must be quoted if +they are to be matched literally. +

+ +The special pattern characters have the following meanings: +

+ + +

+
* + +
+Matches any string, including the null string. +
? + +
+Matches any single character. +
[...] + +
+Matches any one of the enclosed characters. A pair of characters +separated by a hyphen denotes a +range expression; +any character that sorts between those two characters, inclusive, +using the current locale's collating sequence and character set, +is matched. If the first character following the +[ + +is a +! + +or a +^ + +then any character not enclosed is matched. +The sorting order of characters in range expressions is determined by +the current locale and the value of the LC_COLLATE shell variable, +if set. +A +- + +may be matched by including it as the first or last character +in the set. +A +] + +may be matched by including it as the first character +in the set. +
+ +

+ + +Within +[ + +and +], + +character classes can be specified using the syntax +[:class:], where class is one of the +following classes defined in the POSIX standard: +

+

+ +

+ + + +alnum alpha ascii blank cntrl digit graph lower print punct space upper word xdigit +
+ +A character class matches any character belonging to that class. +The word character class matches letters, digits, and the character _. +
+ +

+ + +Within +[ + +and +], + +an equivalence class can be specified using the syntax +[=c=], which matches all characters with the +same collation weight (as defined by the current locale) as +the character c. +
+ +

+ + +Within +[ + +and +], + +the syntax [.symbol.] matches the collating symbol +symbol. +

+ + +

+ +If the extglob shell option is enabled using the shopt +builtin, several extended pattern matching operators are recognized. +In the following description, a pattern-list is a list of one +or more patterns separated by a |. +Composite patterns may be formed using one or more of the following +sub-patterns: +

+ +

+
+
?(pattern-list)
+Matches zero or one occurrence of the given patterns +
*(pattern-list)
+Matches zero or more occurrences of the given patterns +
+(pattern-list)
+Matches one or more occurrences of the given patterns +
@(pattern-list)
+Matches one of the given patterns +
!(pattern-list)
+Matches anything except one of the given patterns +
+ + +  +

Quote Removal

+ +

+ +After the preceding expansions, all unquoted occurrences of the +characters +\, + +aq, + +and " that did not result from one of the above +expansions are removed. +  +

REDIRECTION

+ +Before a command is executed, its input and output +may be +redirected + +using a special notation interpreted by the shell. +Redirection may also be used to open and close files for the +current shell execution environment. The following redirection +operators may precede or appear anywhere within a +simple command + +or may follow a +command. + +Redirections are processed in the order they appear, from +left to right. +

+ +In the following descriptions, if the file descriptor number is +omitted, and the first character of the redirection operator is +<, + +the redirection refers to the standard input (file descriptor +0). If the first character of the redirection operator is +>, + +the redirection refers to the standard output (file descriptor +1). +

+ +The word following the redirection operator in the following +descriptions, unless otherwise noted, is subjected to brace expansion, +tilde expansion, parameter expansion, command substitution, arithmetic +expansion, quote removal, pathname expansion, and word splitting. +If it expands to more than one word, +bash + +reports an error. +

+ +Note that the order of redirections is significant. For example, +the command +

+

+ +ls > dirlist 2>&1 +

+ +

+ +directs both standard output and standard error to the file +dirlist, + +while the command +

+

+ +ls 2>&1 > dirlist +

+ +

+ +directs only the standard output to file +dirlist, + +because the standard error was duplicated as standard output +before the standard output was redirected to +dirlist. + +

+ +Bash handles several filenames specially when they are used in +redirections, as described in the following table: +

+

+ + +

+
/dev/fd/fd + +
+If fd is a valid integer, file descriptor fd is duplicated. +
/dev/stdin + +
+File descriptor 0 is duplicated. +
/dev/stdout + +
+File descriptor 1 is duplicated. +
/dev/stderr + +
+File descriptor 2 is duplicated. +
/dev/tcp/host/port + +
+If host is a valid hostname or Internet address, and port +is an integer port number or service name, bash attempts to open +a TCP connection to the corresponding socket. +
/dev/udp/host/port + +
+If host is a valid hostname or Internet address, and port +is an integer port number or service name, bash attempts to open +a UDP connection to the corresponding socket. + +
+ +

+ +A failure to open or create a file causes the redirection to fail. +

+ +Redirections using file descriptors greater than 9 should be used with +care, as they may conflict with file descriptors the shell uses +internally. +  +

Redirecting Input

+ +

+ +Redirection of input causes the file whose name results from +the expansion of +word + +to be opened for reading on file descriptor +n, + +or the standard input (file descriptor 0) if +n + +is not specified. +

+ +The general format for redirecting input is: +

+

+ +[n]<word +

+ +  +

Redirecting Output

+ +

+ +Redirection of output causes the file whose name results from +the expansion of +word + +to be opened for writing on file descriptor +n, + +or the standard output (file descriptor 1) if +n + +is not specified. If the file does not exist it is created; +if it does exist it is truncated to zero size. +

+ +The general format for redirecting output is: +

+

+ +[n]>word +

+ +

+ +If the redirection operator is +>, + +and the +noclobber + +option to the +set + +builtin has been enabled, the redirection will fail if the file +whose name results from the expansion of word exists and is +a regular file. +If the redirection operator is +>|, + +or the redirection operator is +> + +and the +noclobber + +option to the +set + +builtin command is not enabled, the redirection is attempted even +if the file named by word exists. +  +

Appending Redirected Output

+ +

+ +Redirection of output in this fashion +causes the file whose name results from +the expansion of +word + +to be opened for appending on file descriptor +n, + +or the standard output (file descriptor 1) if +n + +is not specified. If the file does not exist it is created. +

+ +The general format for appending output is: +

+

+ +[n]>>word +

+ +

+ +  +

Redirecting Standard Output and Standard Error

+ +

+ +Bash + +allows both the +standard output (file descriptor 1) and +the standard error output (file descriptor 2) +to be redirected to the file whose name is the +expansion of +word + +with this construct. +

+ +There are two formats for redirecting standard output and +standard error: +

+

+ +&>word +

+ +and +
+>&word +
+ +

+ +Of the two forms, the first is preferred. +This is semantically equivalent to +

+

+ +>word 2>&1 +

+ +  +

Here Documents

+ +

+ +This type of redirection instructs the shell to read input from the +current source until a line containing only +word + +(with no trailing blanks) +is seen. All of +the lines read up to that point are then used as the standard +input for a command. +

+ +The format of here-documents is: +

+

+ +

+<<[-]word
+        here-document
+delimiter
+
+ +
+ +

+ +No parameter expansion, command substitution, arithmetic expansion, +or pathname expansion is performed on +word. + +If any characters in +word + +are quoted, the +delimiter + +is the result of quote removal on +word, + +and the lines in the here-document are not expanded. +If word is unquoted, +all lines of the here-document are subjected to parameter expansion, +command substitution, and arithmetic expansion. In the latter +case, the character sequence +\<newline> + +is ignored, and +\ + +must be used to quote the characters +\, + +$, + +and +`. + +

+ +If the redirection operator is +<<-, + +then all leading tab characters are stripped from input lines and the +line containing +delimiter. + +This allows +here-documents within shell scripts to be indented in a +natural fashion. +  +

Here Strings

+ +A variant of here documents, the format is: +
+

+ +

+<<<word
+
+ +
+ +

+ +The word is expanded and supplied to the command on its standard +input. +  +

Duplicating File Descriptors

+ +

+ +The redirection operator +

+

+ +[n]<&word +

+ +

+ +is used to duplicate input file descriptors. +If +word + +expands to one or more digits, the file descriptor denoted by +n + +is made to be a copy of that file descriptor. +If the digits in +word + +do not specify a file descriptor open for input, a redirection error occurs. +If +word + +evaluates to +-, + +file descriptor +n + +is closed. If +n + +is not specified, the standard input (file descriptor 0) is used. +

+ +The operator +

+

+ +[n]>&word +

+ +

+ +is used similarly to duplicate output file descriptors. If +n + +is not specified, the standard output (file descriptor 1) is used. +If the digits in +word + +do not specify a file descriptor open for output, a redirection error occurs. +As a special case, if n is omitted, and word does not +expand to one or more digits, the standard output and standard +error are redirected as described previously. +  +

Moving File Descriptors

+ +

+ +The redirection operator +

+

+ +[n]<&digit- +

+ +

+ +moves the file descriptor digit to file descriptor +n, + +or the standard input (file descriptor 0) if n is not specified. +digit is closed after being duplicated to n. +

+ +Similarly, the redirection operator +

+

+ +[n]>&digit- +

+ +

+ +moves the file descriptor digit to file descriptor +n, + +or the standard output (file descriptor 1) if n is not specified. +  +

Opening File Descriptors for Reading and Writing

+ +

+ +The redirection operator +

+

+ +[n]<>word +

+ +

+ +causes the file whose name is the expansion of +word + +to be opened for both reading and writing on file descriptor +n, + +or on file descriptor 0 if +n + +is not specified. If the file does not exist, it is created. +  +

ALIASES

+ +Aliases allow a string to be substituted for a word when it is used +as the first word of a simple command. +The shell maintains a list of aliases that may be set and unset with the +alias + +and +unalias + +builtin commands (see +SHELL BUILTIN COMMANDS + + +below). +The first word of each simple command, if unquoted, +is checked to see if it has an +alias. If so, that word is replaced by the text of the alias. +The characters /, $, `, and = and +any of the shell metacharacters or quoting characters +listed above may not appear in an alias name. +The replacement text may contain any valid shell input, +including shell metacharacters. +The first word of the replacement text is tested +for aliases, but a word that is identical to an alias being expanded +is not expanded a second time. +This means that one may alias +ls + +to +ls -F, + +for instance, and +bash + +does not try to recursively expand the replacement text. +If the last character of the alias value is a +blank, + +then the next command +word following the alias is also checked for alias expansion. +

+ +Aliases are created and listed with the +alias + +command, and removed with the +unalias + +command. +

+ +There is no mechanism for using arguments in the replacement text. +If arguments are needed, a shell function should be used (see +FUNCTIONS + + +below). +

+ +Aliases are not expanded when the shell is not interactive, unless +the +expand_aliases + +shell option is set using +shopt + +(see the description of +shopt + +under +SHELL BUILTIN COMMANDS +below). +

+ +The rules concerning the definition and use of aliases are +somewhat confusing. +Bash + +always reads at least one complete line +of input before executing any +of the commands on that line. Aliases are expanded when a +command is read, not when it is executed. Therefore, an +alias definition appearing on the same line as another +command does not take effect until the next line of input is read. +The commands following the alias definition +on that line are not affected by the new alias. +This behavior is also an issue when functions are executed. +Aliases are expanded when a function definition is read, +not when the function is executed, because a function definition +is itself a compound command. As a consequence, aliases +defined in a function are not available until after that +function is executed. To be safe, always put +alias definitions on a separate line, and do not use +alias + +in compound commands. +

+ +For almost every purpose, aliases are superseded by +shell functions. +  +

FUNCTIONS

+ +A shell function, defined as described above under +SHELL GRAMMAR, + + +stores a series of commands for later execution. +When the name of a shell function is used as a simple command name, +the list of commands associated with that function name is executed. +Functions are executed in the context of the +current shell; no new process is created to interpret +them (contrast this with the execution of a shell script). +When a function is executed, the arguments to the +function become the positional parameters +during its execution. +The special parameter +# + +is updated to reflect the change. Special parameter 0 +is unchanged. +The first element of the +FUNCNAME + + +variable is set to the name of the function while the function +is executing. +All other aspects of the shell execution +environment are identical between a function and its caller +with the exception that the +DEBUG + + +and +RETURN + +traps (see the description of the +trap + +builtin under +SHELL BUILTIN COMMANDS + + +below) are not inherited unless the function has been given the +trace attribute (see the description of the +declare + + +builtin below) or the +-o functrace shell option has been enabled with +the set builtin +(in which case all functions inherit the DEBUG and RETURN traps). +

+ +Variables local to the function may be declared with the +local + +builtin command. Ordinarily, variables and their values +are shared between the function and its caller. +

+ +If the builtin command +return + +is executed in a function, the function completes and +execution resumes with the next command after the function +call. +Any command associated with the RETURN trap is executed +before execution resumes. +When a function completes, the values of the +positional parameters and the special parameter +# + +are restored to the values they had prior to the function's +execution. +

+ +Function names and definitions may be listed with the +-f + +option to the +declare + +or +typeset + +builtin commands. The +-F + +option to +declare + +or +typeset + +will list the function names only +(and optionally the source file and line number, if the extdebug +shell option is enabled). +Functions may be exported so that subshells +automatically have them defined with the +-f + +option to the +export + +builtin. +A function definition may be deleted using the -f option to +the +unset + +builtin. +Note that shell functions and variables with the same name may result +in multiple identically-named entries in the environment passed to the +shell's children. +Care should be taken in cases where this may cause a problem. +

+ +Functions may be recursive. No limit is imposed on the number +of recursive calls. +  +

ARITHMETIC EVALUATION

+ +The shell allows arithmetic expressions to be evaluated, under +certain circumstances (see the let and declare builtin +commands and Arithmetic Expansion). +Evaluation is done in fixed-width integers with no check for overflow, +though division by 0 is trapped and flagged as an error. +The operators and their precedence, associativity, and values +are the same as in the C language. +The following list of operators is grouped into levels of +equal-precedence operators. +The levels are listed in order of decreasing precedence. +

+ + +

+
id++ id-- + +
+variable post-increment and post-decrement +
++id --id + +
+variable pre-increment and pre-decrement +
- + + +
+unary minus and plus +
! ~ + +
+logical and bitwise negation +
** + +
+exponentiation +
* / % + +
+multiplication, division, remainder +
+ - + +
+addition, subtraction +

|| + +
+logical OR +
expr?expr:expr + +
+conditional operator +
= *= /= %= += -= <<= >>= &= ^= |= + +
+assignment +
expr1 , expr2 + +
+comma + +
+

+ +Shell variables are allowed as operands; parameter expansion is +performed before the expression is evaluated. +Within an expression, shell variables may also be referenced by name +without using the parameter expansion syntax. +A shell variable that is null or unset evaluates to 0 when referenced +by name without using the parameter expansion syntax. +The value of a variable is evaluated as an arithmetic expression +when it is referenced, or when a variable which has been given the +integer attribute using declare -i is assigned a value. +A null value evaluates to 0. +A shell variable need not have its integer attribute +turned on to be used in an expression. +

+ +Constants with a leading 0 are interpreted as octal numbers. +A leading 0x or 0X denotes hexadecimal. +Otherwise, numbers take the form [base#]n, where base +is a decimal number between 2 and 64 representing the arithmetic +base, and n is a number in that base. +If base# is omitted, then base 10 is used. +The digits greater than 9 are represented by the lowercase letters, +the uppercase letters, @, and _, in that order. +If base is less than or equal to 36, lowercase and uppercase +letters may be used interchangeably to represent numbers between 10 +and 35. +

+ +Operators are evaluated in order of precedence. Sub-expressions in +parentheses are evaluated first and may override the precedence +rules above. +  +

CONDITIONAL EXPRESSIONS

+ +Conditional expressions are used by the [[ compound command and +the test and [ builtin commands to test file attributes +and perform string and arithmetic comparisons. +Expressions are formed from the following unary or binary primaries. +If any file argument to one of the primaries is of the form +/dev/fd/n, then file descriptor n is checked. +If the file argument to one of the primaries is one of +/dev/stdin, /dev/stdout, or /dev/stderr, file +descriptor 0, 1, or 2, respectively, is checked. +

+ +Unless otherwise specified, primaries that operate on files follow symbolic +links and operate on the target of the link, rather than the link itself. +

+ +

+  +

SIMPLE COMMAND EXPANSION

+ +When a simple command is executed, the shell performs the following +expansions, assignments, and redirections, from left to right. +
+
1.
+The words that the parser has marked as variable assignments (those +preceding the command name) and redirections are saved for later +processing. +
2.
+The words that are not variable assignments or redirections are +expanded. If any words remain after expansion, the first word +is taken to be the name of the command and the remaining words are +the arguments. +
3.
+Redirections are performed as described above under +REDIRECTION. + + +
4.
+The text after the = in each variable assignment undergoes tilde +expansion, parameter expansion, command substitution, arithmetic expansion, +and quote removal before being assigned to the variable. +
+

+ +If no command name results, the variable assignments affect the current +shell environment. Otherwise, the variables are added to the environment +of the executed command and do not affect the current shell environment. +If any of the assignments attempts to assign a value to a readonly variable, +an error occurs, and the command exits with a non-zero status. +

+ +If no command name results, redirections are performed, but do not +affect the current shell environment. A redirection error causes the +command to exit with a non-zero status. +

+ +If there is a command name left after expansion, execution proceeds as +described below. Otherwise, the command exits. If one of the expansions +contained a command substitution, the exit status of the command is +the exit status of the last command substitution performed. If there +were no command substitutions, the command exits with a status of zero. +  +

COMMAND EXECUTION

+ +After a command has been split into words, if it results in a +simple command and an optional list of arguments, the following +actions are taken. +

+ +If the command name contains no slashes, the shell attempts to +locate it. If there exists a shell function by that name, that +function is invoked as described above in +FUNCTIONS. + + +If the name does not match a function, the shell searches for +it in the list of shell builtins. If a match is found, that +builtin is invoked. +

+ +If the name is neither a shell function nor a builtin, +and contains no slashes, +bash + +searches each element of the +PATH + + +for a directory containing an executable file by that name. +Bash + +uses a hash table to remember the full pathnames of executable +files (see +hash + +under +SHELL BUILTIN COMMANDS + + +below). +A full search of the directories in +PATH + + +is performed only if the command is not found in the hash table. +If the search is unsuccessful, the shell prints an error +message and returns an exit status of 127. +

+ +If the search is successful, or if the command name contains +one or more slashes, the shell executes the named program in a +separate execution environment. +Argument 0 is set to the name given, and the remaining arguments +to the command are set to the arguments given, if any. +

+ +If this execution fails because the file is not in executable +format, and the file is not a directory, it is assumed to be +a shell script, a file +containing shell commands. A subshell is spawned to execute +it. This subshell reinitializes itself, so +that the effect is as if a new shell had been invoked +to handle the script, with the exception that the locations of +commands remembered by the parent (see +hash + +below under +SHELL BUILTIN COMMANDS) +are retained by the child. +

+ +If the program is a file beginning with +#!, + +the remainder of the first line specifies an interpreter +for the program. The shell executes the +specified interpreter on operating systems that do not +handle this executable format themselves. The arguments to the +interpreter consist of a single optional argument following the +interpreter name on the first line of the program, followed +by the name of the program, followed by the command +arguments, if any. +  +

COMMAND EXECUTION ENVIRONMENT

+ +The shell has an execution environment, which consists of the +following: +

+

+
*
+open files inherited by the shell at invocation, as modified by +redirections supplied to the exec builtin +
*
+the current working directory as set by cd, pushd, or +popd, or inherited by the shell at invocation +
*
+the file creation mode mask as set by umask or inherited from +the shell's parent +
*
+current traps set by trap +
*
+shell parameters that are set by variable assignment or with set +or inherited from the shell's parent in the environment +
*
+shell functions defined during execution or inherited from the shell's +parent in the environment +
*
+options enabled at invocation (either by default or with command-line +arguments) or by set +
*
+options enabled by shopt +
*
+shell aliases defined with alias +
*
+various process IDs, including those of background jobs, the value +of $$, and the value of $PPID +
+

+ +When a simple command other than a builtin or shell function +is to be executed, it +is invoked in a separate execution environment that consists of +the following. Unless otherwise noted, the values are inherited +from the shell. +

+

+
*
+the shell's open files, plus any modifications and additions specified +by redirections to the command +
*
+the current working directory +
*
+the file creation mode mask +
*
+shell variables and functions marked for export, along with variables +exported for the command, passed in the environment +
*
+traps caught by the shell are reset to the values inherited from the +shell's parent, and traps ignored by the shell are ignored +
+

+ +A command invoked in this separate environment cannot affect the +shell's execution environment. +

+ +Command substitution, commands grouped with parentheses, +and asynchronous commands are invoked in a +subshell environment that is a duplicate of the shell environment, +except that traps caught by the shell are reset to the values +that the shell inherited from its parent at invocation. Builtin +commands that are invoked as part of a pipeline are also executed in a +subshell environment. Changes made to the subshell environment +cannot affect the shell's execution environment. +

+ +If a command is followed by a & and job control is not active, the +default standard input for the command is the empty file /dev/null. +Otherwise, the invoked command inherits the file descriptors of the calling +shell as modified by redirections. +  +

ENVIRONMENT

+ +When a program is invoked it is given an array of strings +called the +environment. + +This is a list of +name-value pairs, of the form +name=value. + +

+ +The shell provides several ways to manipulate the environment. +On invocation, the shell scans its own environment and +creates a parameter for each name found, automatically marking +it for +export + +to child processes. Executed commands inherit the environment. +The +export + +and +declare -x + +commands allow parameters and functions to be added to and +deleted from the environment. If the value of a parameter +in the environment is modified, the new value becomes part +of the environment, replacing the old. The environment +inherited by any executed command consists of the shell's +initial environment, whose values may be modified in the shell, +less any pairs removed by the +unset + +command, plus any additions via the +export + +and +declare -x + +commands. +

+ +The environment for any +simple command + +or function may be augmented temporarily by prefixing it with +parameter assignments, as described above in +PARAMETERS. + + +These assignment statements affect only the environment seen +by that command. +

+ +If the +-k + +option is set (see the +set + +builtin command below), then +all + +parameter assignments are placed in the environment for a command, +not just those that precede the command name. +

+ +When +bash + +invokes an external command, the variable +_ + +is set to the full file name of the command and passed to that +command in its environment. +  +

EXIT STATUS

+ +For the shell's purposes, a command which exits with a +zero exit status has succeeded. An exit status of zero +indicates success. A non-zero exit status indicates failure. +When a command terminates on a fatal signal N, bash uses +the value of 128+N as the exit status. +

+ +If a command is not found, the child process created to +execute it returns a status of 127. If a command is found +but is not executable, the return status is 126. +

+ +If a command fails because of an error during expansion or redirection, +the exit status is greater than zero. +

+ +Shell builtin commands return a status of 0 (true) if +successful, and non-zero (false) if an error occurs +while they execute. +All builtins return an exit status of 2 to indicate incorrect usage. +

+ +Bash itself returns the exit status of the last command +executed, unless a syntax error occurs, in which case it exits +with a non-zero value. See also the exit builtin +command below. +  +

SIGNALS

+ +When bash is interactive, in the absence of any traps, it ignores +SIGTERM + + +(so that kill 0 does not kill an interactive shell), +and +SIGINT + + +is caught and handled (so that the wait builtin is interruptible). +In all cases, bash ignores +SIGQUIT. + + +If job control is in effect, +bash + +ignores +SIGTTIN, + + +SIGTTOU, + + +and +SIGTSTP. + + +

+ +Non-builtin commands run by bash have signal handlers +set to the values inherited by the shell from its parent. +When job control is not in effect, asynchronous commands +ignore +SIGINT + + +and +SIGQUIT + + +in addition to these inherited handlers. +Commands run as a result of command substitution ignore the +keyboard-generated job control signals +SIGTTIN, + + +SIGTTOU, + + +and +SIGTSTP. + + +

+ +The shell exits by default upon receipt of a +SIGHUP. + + +Before exiting, an interactive shell resends the +SIGHUP + + +to all jobs, running or stopped. +Stopped jobs are sent +SIGCONT + + +to ensure that they receive the +SIGHUP. + + +To prevent the shell from +sending the signal to a particular job, it should be removed from the +jobs table with the +disown + +builtin (see +SHELL BUILTIN COMMANDS + + +below) or marked +to not receive +SIGHUP + + +using +disown -h. + +

+ +If the +huponexit + +shell option has been set with +shopt, + +bash + +sends a +SIGHUP + + +to all jobs when an interactive login shell exits. +

+ +If bash is waiting for a command to complete and receives a signal +for which a trap has been set, the trap will not be executed until +the command completes. +When bash is waiting for an asynchronous command via the wait +builtin, the reception of a signal for which a trap has been set will +cause the wait builtin to return immediately with an exit status +greater than 128, immediately after which the trap is executed. +  +

JOB CONTROL

+ +Job control + +refers to the ability to selectively stop (suspend) +the execution of processes and continue (resume) +their execution at a later point. A user typically employs +this facility via an interactive interface supplied jointly +by the system's terminal driver and +bash. + +

+ +The shell associates a +job + +with each pipeline. It keeps a table of currently executing +jobs, which may be listed with the +jobs + +command. When +bash + +starts a job asynchronously (in the +background), + +it prints a line that looks like: +

+

+ +[1] 25647 +

+ +

+ +indicating that this job is job number 1 and that the process ID +of the last process in the pipeline associated with this job is 25647. +All of the processes in a single pipeline are members of the same job. +Bash + +uses the +job + +abstraction as the basis for job control. +

+ +To facilitate the implementation of the user interface to job +control, the operating system maintains the notion of a current terminal +process group ID. Members of this process group (processes whose +process group ID is equal to the current terminal process group ID) +receive keyboard-generated signals such as +SIGINT. + + +These processes are said to be in the +foreground. + +Background + +processes are those whose process group ID differs from the terminal's; +such processes are immune to keyboard-generated signals. +Only foreground processes are allowed to read from or write to the +terminal. Background processes which attempt to read from (write to) the +terminal are sent a +SIGTTIN (SIGTTOU) + + +signal by the terminal driver, +which, unless caught, suspends the process. +

+ +If the operating system on which +bash + +is running supports +job control, +bash + +contains facilities to use it. +Typing the +suspend + +character (typically +^Z, + +Control-Z) while a process is running +causes that process to be stopped and returns control to +bash. + +Typing the +delayed suspend + +character (typically +^Y, + +Control-Y) causes the process to be stopped when it +attempts to read input from the terminal, and control to +be returned to +bash. + +The user may then manipulate the state of this job, using the +bg + +command to continue it in the background, the +fg + +command to continue it in the foreground, or +the +kill + +command to kill it. A ^Z takes effect immediately, +and has the additional side effect of causing pending output +and typeahead to be discarded. +

+ +There are a number of ways to refer to a job in the shell. +The character +% + +introduces a job name. Job number +n + +may be referred to as +%n. + +A job may also be referred to using a prefix of the name used to +start it, or using a substring that appears in its command line. +For example, +%ce + +refers to a stopped +ce + +job. If a prefix matches more than one job, +bash + +reports an error. Using +%?ce, + +on the other hand, refers to any job containing the string +ce + +in its command line. If the substring matches more than one job, +bash + +reports an error. The symbols +%% + +and +%+ + +refer to the shell's notion of the +current job, + +which is the last job stopped while it was in +the foreground or started in the background. +The +previous job + +may be referenced using +%-. + +In output pertaining to jobs (e.g., the output of the +jobs + +command), the current job is always flagged with a ++, + +and the previous job with a +-. + +A single % (with no accompanying job specification) also refers to the +current job. +

+ +Simply naming a job can be used to bring it into the +foreground: +%1 + +is a synonym for +``fg %1'', +bringing job 1 from the background into the foreground. +Similarly, +``%1 &'' + +resumes job 1 in the background, equivalent to +``bg %1''. +

+ +The shell learns immediately whenever a job changes state. +Normally, +bash + +waits until it is about to print a prompt before reporting +changes in a job's status so as to not interrupt +any other output. If the +-b + +option to the +set + +builtin command +is enabled, +bash + +reports such changes immediately. +Any trap on +SIGCHLD + + +is executed for each child that exits. +

+ +If an attempt to exit +bash + +is made while jobs are stopped, the shell prints a warning message. The +jobs + +command may then be used to inspect their status. +If a second attempt to exit is made without an intervening command, +the shell does not print another warning, and the stopped +jobs are terminated. +  +

PROMPTING

+ +When executing interactively, +bash + +displays the primary prompt +PS1 + + +when it is ready to read a command, and the secondary prompt +PS2 + + +when it needs more input to complete a command. +Bash + +allows these prompt strings to be customized by inserting a number of +backslash-escaped special characters that are decoded as follows: +
+ +
+
\a + +
+an ASCII bell character (07) +
\d + +
+the date in "Weekday Month Date" format (e.g., "Tue May 26") +
\D{format} + +
+the format is passed to strftime(3) and the result is inserted +into the prompt string; an empty format results in a locale-specific +time representation. The braces are required +
\e + +
+an ASCII escape character (033) +
\h + +
+the hostname up to the first `.' +
\H + +
+the hostname +
\j + +
+the number of jobs currently managed by the shell +
\l + +
+the basename of the shell's terminal device name +
\n + +
+newline +
\r + +
+carriage return +
\s + +
+the name of the shell, the basename of +$0 + +(the portion following the final slash) +
\t + +
+the current time in 24-hour HH:MM:SS format +
\T + +
+the current time in 12-hour HH:MM:SS format +
\@ + +
+the current time in 12-hour am/pm format +
\A + +
+the current time in 24-hour HH:MM format +
\u + +
+the username of the current user +
\v + +
+the version of bash (e.g., 2.00) +
\V + +
+the release of bash, version + patch level (e.g., 2.00.0) +
\w + +
+the current working directory, with $HOME abbreviated with a tilde +
\W + +
+the basename of the current working directory, with $HOME +abbreviated with a tilde +
\! + +
+the history number of this command +
\# + +
+the command number of this command +
\$ + +
+if the effective UID is 0, a +#, + +otherwise a +$ + +
\nnn + +
+the character corresponding to the octal number nnn +
\\ + +
+a backslash +
\[ + +
+begin a sequence of non-printing characters, which could be used to +embed a terminal control sequence into the prompt +
\] + +
+end a sequence of non-printing characters + +
+ +

+ +The command number and the history number are usually different: +the history number of a command is its position in the history +list, which may include commands restored from the history file +(see +HISTORY + + +below), while the command number is the position in the sequence +of commands executed during the current shell session. +After the string is decoded, it is expanded via +parameter expansion, command substitution, arithmetic +expansion, and quote removal, subject to the value of the +promptvars + +shell option (see the description of the +shopt + +command under +SHELL BUILTIN COMMANDS + + +below). +  +

READLINE

+ +This is the library that handles reading input when using an interactive +shell, unless the +--noediting + +option is given at shell invocation. +By default, the line editing commands are similar to those of emacs. +A vi-style line editing interface is also available. +To turn off line editing after the shell is running, use the ++o emacs + +or ++o vi + +options to the +set + +builtin (see +SHELL BUILTIN COMMANDS + + +below). +  +

Readline Notation

+ +

+ +In this section, the emacs-style notation is used to denote +keystrokes. Control keys are denoted by C-key, e.g., C-n +means Control-N. Similarly, +meta + +keys are denoted by M-key, so M-x means Meta-X. (On keyboards +without a +meta + +key, M-x means ESC x, i.e., press the Escape key +then the +x + +key. This makes ESC the meta prefix. +The combination M-C-x means ESC-Control-x, +or press the Escape key +then hold the Control key while pressing the +x + +key.) +

+ +Readline commands may be given numeric +arguments, + +which normally act as a repeat count. +Sometimes, however, it is the sign of the argument that is significant. +Passing a negative argument to a command that acts in the forward +direction (e.g., kill-line) causes that command to act in a +backward direction. +Commands whose behavior with arguments deviates from this are noted +below. +

+ +When a command is described as killing text, the text +deleted is saved for possible future retrieval +(yanking). The killed text is saved in a +kill ring. Consecutive kills cause the text to be +accumulated into one unit, which can be yanked all at once. +Commands which do not kill text separate the chunks of text +on the kill ring. +  +

Readline Initialization

+ +

+ +Readline is customized by putting commands in an initialization +file (the inputrc file). +The name of this file is taken from the value of the +INPUTRC + + +variable. If that variable is unset, the default is +~/.inputrc. + +When a program which uses the readline library starts up, the +initialization file is read, and the key bindings and variables +are set. +There are only a few basic constructs allowed in the +readline initialization file. +Blank lines are ignored. +Lines beginning with a # are comments. +Lines beginning with a $ indicate conditional constructs. +Other lines denote key bindings and variable settings. +

+ +The default key-bindings may be changed with an +inputrc + +file. +Other programs that use this library may add their own commands +and bindings. +

+ +For example, placing +

+

+ +M-Control-u: universal-argument +

+ +or +
+C-Meta-u: universal-argument +
+ +into the +inputrc + +would make M-C-u execute the readline command +universal-argument. + +

+ +The following symbolic character names are recognized: +RUBOUT, + +DEL, + +ESC, + +LFD, + +NEWLINE, + +RET, + +RETURN, + +SPC, + +SPACE, + +and +TAB. + +

+ +In addition to command names, readline allows keys to be bound +to a string that is inserted when the key is pressed (a macro). +  +

Readline Key Bindings

+ +

+ +The syntax for controlling key bindings in the +inputrc + +file is simple. All that is required is the name of the +command or the text of a macro and a key sequence to which +it should be bound. The name may be specified in one of two ways: +as a symbolic key name, possibly with Meta- or Control- +prefixes, or as a key sequence. +

+ +When using the form keyname:function-name or macro, +keyname + +is the name of a key spelled out in English. For example: +

+

+Control-u: universal-argument +
+ +Meta-Rubout: backward-kill-word +
+ +Control-o: "> output" +
+ +

+ +In the above example, +C-u + +is bound to the function +universal-argument, + +M-DEL + +is bound to the function +backward-kill-word, + +and +C-o + +is bound to run the macro +expressed on the right hand side (that is, to insert the text +> output + +into the line). +

+ +In the second form, "keyseq":function-name or macro, +keyseq + +differs from +keyname + +above in that strings denoting +an entire key sequence may be specified by placing the sequence +within double quotes. Some GNU Emacs style key escapes can be +used, as in the following example, but the symbolic character names +are not recognized. +

+

+"\C-u": universal-argument +
+ +"\C-x\C-r": re-read-init-file +
+ +"\e[11~": "Function Key 1" +
+ +

+ +In this example, +C-u + +is again bound to the function +universal-argument. + +C-x C-r + +is bound to the function +re-read-init-file, + +and +ESC [ 1 1 ~ + +is bound to insert the text +Function Key 1. + +

+ +The full set of GNU Emacs style escape sequences is +

+ +
+
\C- + +
+control prefix +
\M- + +
+meta prefix +
\e + +
+an escape character +
\\ + +
+backslash +
\ + +
+literal " +
\aq + +
+literal aq +
+ + +

+ +In addition to the GNU Emacs style escape sequences, a second +set of backslash escapes is available: +

+ +
+
\a + +
+alert (bell) +
\b + +
+backspace +
\d + +
+delete +
\f + +
+form feed +
\n + +
+newline +
\r + +
+carriage return +
\t + +
+horizontal tab +
\v + +
+vertical tab +
\nnn + +
+the eight-bit character whose value is the octal value nnn +(one to three digits) +
\xHH + +
+the eight-bit character whose value is the hexadecimal value HH +(one or two hex digits) +
+ + +

+ +When entering the text of a macro, single or double quotes must +be used to indicate a macro definition. +Unquoted text is assumed to be a function name. +In the macro body, the backslash escapes described above are expanded. +Backslash will quote any other character in the macro text, +including " and aq. +

+ +Bash + +allows the current readline key bindings to be displayed or modified +with the +bind + +builtin command. The editing mode may be switched during interactive +use by using the +-o + +option to the +set + +builtin command (see +SHELL BUILTIN COMMANDS + + +below). +  +

Readline Variables

+ +

+ +Readline has variables that can be used to further customize its +behavior. A variable may be set in the +inputrc + +file with a statement of the form +

+

+ +set variable-name value +

+ +

+ +Except where noted, readline variables can take the values +On + +or +Off + +(without regard to case). +Unrecognized variable names are ignored. +When a variable value is read, empty or null values, "on" (case-insensitive), +and "1" are equivalent to On. All other values are equivalent to +Off. +The variables and their default values are: +

+ + +

+
bell-style (audible) + +
+Controls what happens when readline wants to ring the terminal bell. +If set to none, readline never rings the bell. If set to +visible, readline uses a visible bell if one is available. +If set to audible, readline attempts to ring the terminal's bell. +
bind-tty-special-chars (On) + +
+If set to On, readline attempts to bind the control characters +treated specially by the kernel's terminal driver to their readline +equivalents. +
comment-begin (``#'') + +
+The string that is inserted when the readline +insert-comment + +command is executed. +This command is bound to +M-# + +in emacs mode and to +# + +in vi command mode. +
completion-ignore-case (Off) + +
+If set to On, readline performs filename matching and completion +in a case-insensitive fashion. +
completion-query-items (100) + +
+This determines when the user is queried about viewing +the number of possible completions +generated by the possible-completions command. +It may be set to any integer value greater than or equal to +zero. If the number of possible completions is greater than +or equal to the value of this variable, the user is asked whether +or not he wishes to view them; otherwise they are simply listed +on the terminal. +
convert-meta (On) + +
+If set to On, readline will convert characters with the +eighth bit set to an ASCII key sequence +by stripping the eighth bit and prefixing an +escape character (in effect, using escape as the meta prefix). +
disable-completion (Off) + +
+If set to On, readline will inhibit word completion. Completion +characters will be inserted into the line as if they had been +mapped to self-insert. +
editing-mode (emacs) + +
+Controls whether readline begins with a set of key bindings similar +to emacs or vi. +editing-mode + +can be set to either +emacs + +or +vi. + +
enable-keypad (Off) + +
+When set to On, readline will try to enable the application +keypad when it is called. Some systems need this to enable the +arrow keys. +
expand-tilde (Off) + +
+If set to on, tilde expansion is performed when readline +attempts word completion. +
history-preserve-point (Off) + +
+If set to on, the history code attempts to place point at the +same location on each history line retrieved with previous-history +or next-history. +
horizontal-scroll-mode (Off) + +
+When set to On, makes readline use a single line for display, +scrolling the input horizontally on a single screen line when it +becomes longer than the screen width rather than wrapping to a new line. +
input-meta (Off) + +
+If set to On, readline will enable eight-bit input (that is, +it will not strip the high bit from the characters it reads), +regardless of what the terminal claims it can support. The name +meta-flag + +is a synonym for this variable. +
isearch-terminators (``C-[C-J'') + +
+The string of characters that should terminate an incremental +search without subsequently executing the character as a command. +If this variable has not been given a value, the characters +ESC and C-J will terminate an incremental search. +
keymap (emacs) + +
+Set the current readline keymap. The set of valid keymap names is +emacs, emacs-standard, emacs-meta, emacs-ctlx, vi, +vi-command, and +vi-insert. + +vi is equivalent to vi-command; emacs is +equivalent to emacs-standard. The default value is +emacs; + +the value of +editing-mode + +also affects the default keymap. +
mark-directories (On) + +
+If set to On, completed directory names have a slash +appended. +
mark-modified-lines (Off) + +
+If set to On, history lines that have been modified are displayed +with a preceding asterisk (*). +
mark-symlinked-directories (Off) + +
+If set to On, completed names which are symbolic links to directories +have a slash appended (subject to the value of +mark-directories). +
match-hidden-files (On) + +
+This variable, when set to On, causes readline to match files whose +names begin with a `.' (hidden files) when performing filename +completion, unless the leading `.' is +supplied by the user in the filename to be completed. +
output-meta (Off) + +
+If set to On, readline will display characters with the +eighth bit set directly rather than as a meta-prefixed escape +sequence. +
page-completions (On) + +
+If set to On, readline uses an internal more-like pager +to display a screenful of possible completions at a time. +
print-completions-horizontally (Off) + +
+If set to On, readline will display completions with matches +sorted horizontally in alphabetical order, rather than down the screen. +
show-all-if-ambiguous (Off) + +
+This alters the default behavior of the completion functions. If +set to +on, + +words which have more than one possible completion cause the +matches to be listed immediately instead of ringing the bell. +
show-all-if-unmodified (Off) + +
+This alters the default behavior of the completion functions in +a fashion similar to show-all-if-ambiguous. +If set to +on, + +words which have more than one possible completion without any +possible partial completion (the possible completions don't share +a common prefix) cause the matches to be listed immediately instead +of ringing the bell. +
visible-stats (Off) + +
+If set to On, a character denoting a file's type as reported +by stat(2) is appended to the filename when listing possible +completions. + +
+  +

Readline Conditional Constructs

+ +

+ +Readline implements a facility similar in spirit to the conditional +compilation features of the C preprocessor which allows key +bindings and variable settings to be performed as the result +of tests. There are four parser directives used. +

+
$if
+The +$if + +construct allows bindings to be made based on the +editing mode, the terminal being used, or the application using +readline. The text of the test extends to the end of the line; +no characters are required to isolate it. +
+
+
mode
+The mode= form of the $if directive is used to test +whether readline is in emacs or vi mode. +This may be used in conjunction +with the set keymap command, for instance, to set bindings in +the emacs-standard and emacs-ctlx keymaps only if +readline is starting out in emacs mode. +
term
+The term= form may be used to include terminal-specific +key bindings, perhaps to bind the key sequences output by the +terminal's function keys. The word on the right side of the += + +is tested against the both full name of the terminal and the portion +of the terminal name before the first -. This allows +sun + +to match both +sun + +and +sun-cmd, + +for instance. +
application
+The application construct is used to include +application-specific settings. Each program using the readline +library sets the application name, and an initialization +file can test for a particular value. +This could be used to bind key sequences to functions useful for +a specific program. For instance, the following command adds a +key sequence that quotes the current or previous word in Bash: +

+

+
+$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+
+ +
+ +
+ +
$endif
+This command, as seen in the previous example, terminates an +$if command. +
$else
+Commands in this branch of the $if directive are executed if +the test fails. +
$include
+This directive takes a single filename as an argument and reads commands +and bindings from that file. For example, the following directive +would read /etc/inputrc: +

+

+
+$include  /etc/inputrc
+
+ +
+ +
+  +

Searching

+ +

+ +Readline provides commands for searching through the command history +(see +HISTORY + + +below) for lines containing a specified string. +There are two search modes: +incremental + +and +non-incremental. + +

+ +Incremental searches begin before the user has finished typing the +search string. +As each character of the search string is typed, readline displays +the next entry from the history matching the string typed so far. +An incremental search requires only as many characters as needed to +find the desired history entry. +The characters present in the value of the isearch-terminators +variable are used to terminate an incremental search. +If that variable has not been assigned a value the Escape and +Control-J characters will terminate an incremental search. +Control-G will abort an incremental search and restore the original +line. +When the search is terminated, the history entry containing the +search string becomes the current line. +

+ +To find other matching entries in the history list, type Control-S or +Control-R as appropriate. +This will search backward or forward in the history for the next +entry matching the search string typed so far. +Any other key sequence bound to a readline command will terminate +the search and execute that command. +For instance, a newline will terminate the search and accept +the line, thereby executing the command from the history list. +

+ +Readline remembers the last incremental search string. If two +Control-Rs are typed without any intervening characters defining a +new search string, any remembered search string is used. +

+ +Non-incremental searches read the entire search string before starting +to search for matching history lines. The search string may be +typed by the user or be part of the contents of the current line. +  +

Readline Command Names

+ +

+ +The following is a list of the names of the commands and the default +key sequences to which they are bound. +Command names without an accompanying key sequence are unbound by default. +In the following descriptions, point refers to the current cursor +position, and mark refers to a cursor position saved by the +set-mark command. +The text between the point and mark is referred to as the region. +  +

Commands for Moving

+ +

+ + +

+
beginning-of-line (C-a) + +
+Move to the start of the current line. +
end-of-line (C-e) + +
+Move to the end of the line. +
forward-char (C-f) + +
+Move forward a character. +
backward-char (C-b) + +
+Move back a character. +
forward-word (M-f) + +
+Move forward to the end of the next word. Words are composed of +alphanumeric characters (letters and digits). +
backward-word (M-b) + +
+Move back to the start of the current or previous word. Words are +composed of alphanumeric characters (letters and digits). +
clear-screen (C-l) + +
+Clear the screen leaving the current line at the top of the screen. +With an argument, refresh the current line without clearing the +screen. +
redraw-current-line + +
+Refresh the current line. + +
+  +

Commands for Manipulating the History

+ +

+ + +

+
accept-line (Newline, Return) + +
+Accept the line regardless of where the cursor is. If this line is +non-empty, add it to the history list according to the state of the +HISTCONTROL + + +variable. If the line is a modified history +line, then restore the history line to its original state. +
previous-history (C-p) + +
+Fetch the previous command from the history list, moving back in +the list. +
next-history (C-n) + +
+Fetch the next command from the history list, moving forward in the +list. +
beginning-of-history (M-<) + +
+Move to the first line in the history. +
end-of-history (M->) + +
+Move to the end of the input history, i.e., the line currently being +entered. +
reverse-search-history (C-r) + +
+Search backward starting at the current line and moving `up' through +the history as necessary. This is an incremental search. +
forward-search-history (C-s) + +
+Search forward starting at the current line and moving `down' through +the history as necessary. This is an incremental search. +
non-incremental-reverse-search-history (M-p) + +
+Search backward through the history starting at the current line +using a non-incremental search for a string supplied by the user. +
non-incremental-forward-search-history (M-n) + +
+Search forward through the history using a non-incremental search for +a string supplied by the user. +
history-search-forward + +
+Search forward through the history for the string of characters +between the start of the current line and the point. +This is a non-incremental search. +
history-search-backward + +
+Search backward through the history for the string of characters +between the start of the current line and the point. +This is a non-incremental search. +
yank-nth-arg (M-C-y) + +
+Insert the first argument to the previous command (usually +the second word on the previous line) at point. +With an argument +n, + +insert the nth word from the previous command (the words +in the previous command begin with word 0). A negative argument +inserts the nth word from the end of the previous command. +Once the argument n is computed, the argument is extracted +as if the "!n" history expansion had been specified. +
yank-last-arg (M-., M-_) + +
+Insert the last argument to the previous command (the last word of +the previous history entry). With an argument, +behave exactly like yank-nth-arg. +Successive calls to yank-last-arg move back through the history +list, inserting the last argument of each line in turn. +The history expansion facilities are used to extract the last argument, +as if the "!$" history expansion had been specified. +
shell-expand-line (M-C-e) + +
+Expand the line as the shell does. This +performs alias and history expansion as well as all of the shell +word expansions. See +HISTORY EXPANSION + + +below for a description of history expansion. +
history-expand-line (M-^) + +
+Perform history expansion on the current line. +See +HISTORY EXPANSION + + +below for a description of history expansion. +
magic-space + +
+Perform history expansion on the current line and insert a space. +See +HISTORY EXPANSION + + +below for a description of history expansion. +
alias-expand-line + +
+Perform alias expansion on the current line. +See +ALIASES + + +above for a description of alias expansion. +
history-and-alias-expand-line + +
+Perform history and alias expansion on the current line. +
insert-last-argument (M-., M-_) + +
+A synonym for yank-last-arg. +
operate-and-get-next (C-o) + +
+Accept the current line for execution and fetch the next line +relative to the current line from the history for editing. Any +argument is ignored. +
edit-and-execute-command (C-xC-e) + +
+Invoke an editor on the current command line, and execute the result as shell +commands. +Bash attempts to invoke +$FCEDIT, + + +$EDITOR, + + +and emacs as the editor, in that order. + +
+  +

Commands for Changing Text

+ +

+ + +

+
delete-char (C-d) + +
+Delete the character at point. If point is at the +beginning of the line, there are no characters in the line, and +the last character typed was not bound to delete-char, +then return +EOF. + + +
backward-delete-char (Rubout) + +
+Delete the character behind the cursor. When given a numeric argument, +save the deleted text on the kill ring. +
forward-backward-delete-char + +
+Delete the character under the cursor, unless the cursor is at the +end of the line, in which case the character behind the cursor is +deleted. +
quoted-insert (C-q, C-v) + +
+Add the next character typed to the line verbatim. This is +how to insert characters like C-q, for example. +
tab-insert (C-v TAB) + +
+Insert a tab character. +
self-insert (a, b, A, 1, !, ...) + +
+Insert the character typed. +
transpose-chars (C-t) + +
+Drag the character before point forward over the character at point, +moving point forward as well. +If point is at the end of the line, then this transposes +the two characters before point. +Negative arguments have no effect. +
transpose-words (M-t) + +
+Drag the word before point past the word after point, +moving point over that word as well. +If point is at the end of the line, this transposes +the last two words on the line. +
upcase-word (M-u) + +
+Uppercase the current (or following) word. With a negative argument, +uppercase the previous word, but do not move point. +
downcase-word (M-l) + +
+Lowercase the current (or following) word. With a negative argument, +lowercase the previous word, but do not move point. +
capitalize-word (M-c) + +
+Capitalize the current (or following) word. With a negative argument, +capitalize the previous word, but do not move point. +
overwrite-mode + +
+Toggle overwrite mode. With an explicit positive numeric argument, +switches to overwrite mode. With an explicit non-positive numeric +argument, switches to insert mode. This command affects only +emacs mode; vi mode does overwrite differently. +Each call to readline() starts in insert mode. +In overwrite mode, characters bound to self-insert replace +the text at point rather than pushing the text to the right. +Characters bound to backward-delete-char replace the character +before point with a space. By default, this command is unbound. + +
+  +

Killing and Yanking

+ +

+ + +

+
kill-line (C-k) + +
+Kill the text from point to the end of the line. +
backward-kill-line (C-x Rubout) + +
+Kill backward to the beginning of the line. +
unix-line-discard (C-u) + +
+Kill backward from point to the beginning of the line. +The killed text is saved on the kill-ring. + +
kill-whole-line + +
+Kill all characters on the current line, no matter where point is. +
kill-word (M-d) + +
+Kill from point to the end of the current word, or if between +words, to the end of the next word. +Word boundaries are the same as those used by forward-word. +
backward-kill-word (M-Rubout) + +
+Kill the word behind point. +Word boundaries are the same as those used by backward-word. +
unix-word-rubout (C-w) + +
+Kill the word behind point, using white space as a word boundary. +The killed text is saved on the kill-ring. +
unix-filename-rubout + +
+Kill the word behind point, using white space and the slash character +as the word boundaries. +The killed text is saved on the kill-ring. +
delete-horizontal-space (M-\) + +
+Delete all spaces and tabs around point. +
kill-region + +
+Kill the text in the current region. +
copy-region-as-kill + +
+Copy the text in the region to the kill buffer. +
copy-backward-word + +
+Copy the word before point to the kill buffer. +The word boundaries are the same as backward-word. +
copy-forward-word + +
+Copy the word following point to the kill buffer. +The word boundaries are the same as forward-word. +
yank (C-y) + +
+Yank the top of the kill ring into the buffer at point. +
yank-pop (M-y) + +
+Rotate the kill ring, and yank the new top. Only works following +yank + +or +yank-pop. + + +
+  +

Numeric Arguments

+ +

+ + +

+
digit-argument (M-0, M-1, ..., M--) + +
+Add this digit to the argument already accumulating, or start a new +argument. M-- starts a negative argument. +
universal-argument + +
+This is another way to specify an argument. +If this command is followed by one or more digits, optionally with a +leading minus sign, those digits define the argument. +If the command is followed by digits, executing +universal-argument + +again ends the numeric argument, but is otherwise ignored. +As a special case, if this command is immediately followed by a +character that is neither a digit or minus sign, the argument count +for the next command is multiplied by four. +The argument count is initially one, so executing this function the +first time makes the argument count four, a second time makes the +argument count sixteen, and so on. + +
+  +

Completing

+ +

+ + +

+
complete (TAB) + +
+Attempt to perform completion on the text before point. +Bash + +attempts completion treating the text as a variable (if the +text begins with $), username (if the text begins with +~), hostname (if the text begins with @), or +command (including aliases and functions) in turn. If none +of these produces a match, filename completion is attempted. +
possible-completions (M-?) + +
+List the possible completions of the text before point. +
insert-completions (M-*) + +
+Insert all completions of the text before point +that would have been generated by +possible-completions. +
menu-complete + +
+Similar to complete, but replaces the word to be completed +with a single match from the list of possible completions. +Repeated execution of menu-complete steps through the list +of possible completions, inserting each match in turn. +At the end of the list of completions, the bell is rung +(subject to the setting of bell-style) +and the original text is restored. +An argument of n moves n positions forward in the list +of matches; a negative argument may be used to move backward +through the list. +This command is intended to be bound to TAB, but is unbound +by default. +
delete-char-or-list + +
+Deletes the character under the cursor if not at the beginning or +end of the line (like delete-char). +If at the end of the line, behaves identically to +possible-completions. +This command is unbound by default. +
complete-filename (M-/) + +
+Attempt filename completion on the text before point. +
possible-filename-completions (C-x /) + +
+List the possible completions of the text before point, +treating it as a filename. +
complete-username (M-~) + +
+Attempt completion on the text before point, treating +it as a username. +
possible-username-completions (C-x ~) + +
+List the possible completions of the text before point, +treating it as a username. +
complete-variable (M-$) + +
+Attempt completion on the text before point, treating +it as a shell variable. +
possible-variable-completions (C-x $) + +
+List the possible completions of the text before point, +treating it as a shell variable. +
complete-hostname (M-@) + +
+Attempt completion on the text before point, treating +it as a hostname. +
possible-hostname-completions (C-x @) + +
+List the possible completions of the text before point, +treating it as a hostname. +
complete-command (M-!) + +
+Attempt completion on the text before point, treating +it as a command name. Command completion attempts to +match the text against aliases, reserved words, shell +functions, shell builtins, and finally executable filenames, +in that order. +
possible-command-completions (C-x !) + +
+List the possible completions of the text before point, +treating it as a command name. +
dynamic-complete-history (M-TAB) + +
+Attempt completion on the text before point, comparing +the text against lines from the history list for possible +completion matches. +
complete-into-braces (M-{) + +
+Perform filename completion and insert the list of possible completions +enclosed within braces so the list is available to the shell (see +Brace Expansion + +above). + +
+  +

Keyboard Macros

+ +

+ + +

+
start-kbd-macro (C-x () + +
+Begin saving the characters typed into the current keyboard macro. +
end-kbd-macro (C-x )) + +
+Stop saving the characters typed into the current keyboard macro +and store the definition. +
call-last-kbd-macro (C-x e) + +
+Re-execute the last keyboard macro defined, by making the characters +in the macro appear as if typed at the keyboard. + +
+  +

Miscellaneous

+ +

+ + +

+
re-read-init-file (C-x C-r) + +
+Read in the contents of the inputrc file, and incorporate +any bindings or variable assignments found there. +
abort (C-g) + +
+Abort the current editing command and +ring the terminal's bell (subject to the setting of +bell-style). + +
do-uppercase-version (M-a, M-b, M-x, ...) + +
+If the metafied character x is lowercase, run the command +that is bound to the corresponding uppercase character. +
prefix-meta (ESC) + +
+Metafy the next character typed. +ESC + + +f + +is equivalent to +Meta-f. + +
undo (C-_, C-x C-u) + +
+Incremental undo, separately remembered for each line. +
revert-line (M-r) + +
+Undo all changes made to this line. This is like executing the +undo + +command enough times to return the line to its initial state. +
tilde-expand (M-&) + +
+Perform tilde expansion on the current word. +
set-mark (C-@, M-<space>) + +
+Set the mark to the point. If a +numeric argument is supplied, the mark is set to that position. +
exchange-point-and-mark (C-x C-x) + +
+Swap the point with the mark. The current cursor position is set to +the saved position, and the old cursor position is saved as the mark. +
character-search (C-]) + +
+A character is read and point is moved to the next occurrence of that +character. A negative count searches for previous occurrences. +

+A character is read and point is moved to the previous occurrence of that +character. A negative count searches for subsequent occurrences. +
insert-comment (M-#) + +
+Without a numeric argument, the value of the readline +comment-begin + +variable is inserted at the beginning of the current line. +If a numeric argument is supplied, this command acts as a toggle: if +the characters at the beginning of the line do not match the value +of comment-begin, the value is inserted, otherwise +the characters in comment-begin are deleted from the beginning of +the line. +In either case, the line is accepted as if a newline had been typed. +The default value of +comment-begin causes this command to make the current line +a shell comment. +If a numeric argument causes the comment character to be removed, the line +will be executed by the shell. +
glob-complete-word (M-g) + +
+The word before point is treated as a pattern for pathname expansion, +with an asterisk implicitly appended. This pattern is used to +generate a list of matching file names for possible completions. +
glob-expand-word (C-x *) + +
+The word before point is treated as a pattern for pathname expansion, +and the list of matching file names is inserted, replacing the word. +If a numeric argument is supplied, an asterisk is appended before +pathname expansion. +
glob-list-expansions (C-x g) + +
+The list of expansions that would have been generated by +glob-expand-word + +is displayed, and the line is redrawn. +If a numeric argument is supplied, an asterisk is appended before +pathname expansion. +
dump-functions + +
+Print all of the functions and their key bindings to the +readline output stream. If a numeric argument is supplied, +the output is formatted in such a way that it can be made part +of an inputrc file. +
dump-variables + +
+Print all of the settable readline variables and their values to the +readline output stream. If a numeric argument is supplied, +the output is formatted in such a way that it can be made part +of an inputrc file. +
dump-macros + +
+Print all of the readline key sequences bound to macros and the +strings they output. If a numeric argument is supplied, +the output is formatted in such a way that it can be made part +of an inputrc file. +
display-shell-version (C-x C-v) + +
+Display version information about the current instance of +bash. + + +
+  +

Programmable Completion

+ +

+ +When word completion is attempted for an argument to a command for +which a completion specification (a compspec) has been defined +using the complete builtin (see +SHELL BUILTIN COMMANDS + + +below), the programmable completion facilities are invoked. +

+ +First, the command name is identified. +If a compspec has been defined for that command, the +compspec is used to generate the list of possible completions for the word. +If the command word is a full pathname, a compspec for the full +pathname is searched for first. +If no compspec is found for the full pathname, an attempt is made to +find a compspec for the portion following the final slash. +

+ +Once a compspec has been found, it is used to generate the list of +matching words. +If a compspec is not found, the default bash completion as +described above under Completing is performed. +

+ +First, the actions specified by the compspec are used. +Only matches which are prefixed by the word being completed are +returned. +When the +-f + +or +-d + +option is used for filename or directory name completion, the shell +variable +FIGNORE + + +is used to filter the matches. +

+ +Any completions specified by a filename expansion pattern to the +-G option are generated next. +The words generated by the pattern need not match the word +being completed. +The +GLOBIGNORE + + +shell variable is not used to filter the matches, but the +FIGNORE + + +variable is used. +

+ +Next, the string specified as the argument to the -W option +is considered. +The string is first split using the characters in the +IFS + + +special variable as delimiters. +Shell quoting is honored. +Each word is then expanded using +brace expansion, tilde expansion, parameter and variable expansion, +command substitution, and arithmetic expansion, +as described above under +EXPANSION. + + +The results are split using the rules described above under +Word Splitting. +The results of the expansion are prefix-matched against the word being +completed, and the matching words become the possible completions. +

+ +After these matches have been generated, any shell function or command +specified with the -F and -C options is invoked. +When the command or function is invoked, the +COMP_LINE + + +and +COMP_POINT + + +variables are assigned values as described above under +Shell Variables. +If a shell function is being invoked, the +COMP_WORDS + + +and +COMP_CWORD + + +variables are also set. +When the function or command is invoked, the first argument is the +name of the command whose arguments are being completed, the +second argument is the word being completed, and the third argument +is the word preceding the word being completed on the current command line. +No filtering of the generated completions against the word being completed +is performed; the function or command has complete freedom in generating +the matches. +

+ +Any function specified with -F is invoked first. +The function may use any of the shell facilities, including the +compgen builtin described below, to generate the matches. +It must put the possible completions in the +COMPREPLY + + +array variable. +

+ +Next, any command specified with the -C option is invoked +in an environment equivalent to command substitution. +It should print a list of completions, one per line, to the +standard output. +Backslash may be used to escape a newline, if necessary. +

+ +After all of the possible completions are generated, any filter +specified with the -X option is applied to the list. +The filter is a pattern as used for pathname expansion; a & +in the pattern is replaced with the text of the word being completed. +A literal & may be escaped with a backslash; the backslash +is removed before attempting a match. +Any completion that matches the pattern will be removed from the list. +A leading ! negates the pattern; in this case any completion +not matching the pattern will be removed. +

+ +Finally, any prefix and suffix specified with the -P and -S +options are added to each member of the completion list, and the result is +returned to the readline completion code as the list of possible +completions. +

+ +If the previously-applied actions do not generate any matches, and the +-o dirnames option was supplied to complete when the +compspec was defined, directory name completion is attempted. +

+ +If the -o plusdirs option was supplied to complete when the +compspec was defined, directory name completion is attempted and any +matches are added to the results of the other actions. +

+ +By default, if a compspec is found, whatever it generates is returned +to the completion code as the full set of possible completions. +The default bash completions are not attempted, and the readline +default of filename completion is disabled. +If the -o bashdefault option was supplied to complete when +the compspec was defined, the bash default completions are attempted +if the compspec generates no matches. +If the -o default option was supplied to complete when the +compspec was defined, readline's default completion will be performed +if the compspec (and, if attempted, the default bash completions) +generate no matches. +

+ +When a compspec indicates that directory name completion is desired, +the programmable completion functions force readline to append a slash +to completed names which are symbolic links to directories, subject to +the value of the mark-directories readline variable, regardless +of the setting of the mark-symlinked-directories readline variable. +  +

HISTORY

+ +When the +-o history + +option to the +set + +builtin is enabled, the shell provides access to the +command history, +the list of commands previously typed. +The value of the HISTSIZE variable is used as the +number of commands to save in a history list. +The text of the last +HISTSIZE + + +commands (default 500) is saved. The shell +stores each command in the history list prior to parameter and +variable expansion (see +EXPANSION + + +above) but after history expansion is performed, subject to the +values of the shell variables +HISTIGNORE + + +and +HISTCONTROL. + + +

+ +On startup, the history is initialized from the file named by +the variable +HISTFILE + + +(default ~/.bash_history). +The file named by the value of +HISTFILE + + +is truncated, if necessary, to contain no more than +the number of lines specified by the value of +HISTFILESIZE. + + +When an interactive shell exits, the last +$HISTSIZE + + +lines are copied from the history list to +$HISTFILE. + + +If the +histappend + +shell option is enabled +(see the description of +shopt + +under +SHELL BUILTIN COMMANDS + + +below), the lines are appended to the history file, +otherwise the history file is overwritten. +If +HISTFILE + + +is unset, or if the history file is unwritable, the history is +not saved. After saving the history, the history file is truncated +to contain no more than +HISTFILESIZE + + +lines. If +HISTFILESIZE + + +is not set, no truncation is performed. +

+ +The builtin command +fc + +(see +SHELL BUILTIN COMMANDS + + +below) may be used to list or edit and re-execute a portion of +the history list. +The +history + +builtin may be used to display or modify the history list and +manipulate the history file. +When using command-line editing, search commands +are available in each editing mode that provide access to the +history list. +

+ +The shell allows control over which commands are saved on the history +list. The +HISTCONTROL + + +and +HISTIGNORE + + +variables may be set to cause the shell to save only a subset of the +commands entered. +The +cmdhist + +shell option, if enabled, causes the shell to attempt to save each +line of a multi-line command in the same history entry, adding +semicolons where necessary to preserve syntactic correctness. +The +lithist + +shell option causes the shell to save the command with embedded newlines +instead of semicolons. See the description of the +shopt + +builtin below under +SHELL BUILTIN COMMANDS + + +for information on setting and unsetting shell options. +  +

HISTORY EXPANSION

+ +

+ +The shell supports a history expansion feature that +is similar to the history expansion in +csh. + +This section describes what syntax features are available. This +feature is enabled by default for interactive shells, and can be +disabled using the ++H + +option to the +set + +builtin command (see +SHELL BUILTIN COMMANDS + + +below). Non-interactive shells do not perform history expansion +by default. +

+ +History expansions introduce words from the history list into +the input stream, making it easy to repeat commands, insert the +arguments to a previous command into the current input line, or +fix errors in previous commands quickly. +

+ +History expansion is performed immediately after a complete line +is read, before the shell breaks it into words. +It takes place in two parts. +The first is to determine which line from the history list +to use during substitution. +The second is to select portions of that line for inclusion into +the current one. +The line selected from the history is the event, +and the portions of that line that are acted upon are words. +Various modifiers are available to manipulate the selected words. +The line is broken into words in the same fashion as when reading input, +so that several metacharacter-separated words surrounded by +quotes are considered one word. +History expansions are introduced by the appearance of the +history expansion character, which is ! by default. +Only backslash (\) and single quotes can quote +the history expansion character. +

+ +Several characters inhibit history expansion if found immediately +following the history expansion character, even if it is unquoted: +space, tab, newline, carriage return, and =. +If the extglob shell option is enabled, ( will also +inhibit expansion. +

+ +Several shell options settable with the +shopt + +builtin may be used to tailor the behavior of history expansion. +If the +histverify + +shell option is enabled (see the description of the +shopt + +builtin), and +readline + +is being used, history substitutions are not immediately passed to +the shell parser. +Instead, the expanded line is reloaded into the +readline + +editing buffer for further modification. +If +readline + +is being used, and the +histreedit + +shell option is enabled, a failed history substitution will be reloaded +into the +readline + +editing buffer for correction. +The +-p + +option to the +history + +builtin command may be used to see what a history expansion will +do before using it. +The +-s + +option to the +history + +builtin may be used to add commands to the end of the history list +without actually executing them, so that they are available for +subsequent recall. +

+ +The shell allows control of the various characters used by the +history expansion mechanism (see the description of +histchars + +above under +Shell Variables). + +  +

Event Designators

+ +

+ +An event designator is a reference to a command line entry in the +history list. +

+ + +

+
! + +
+Start a history substitution, except when followed by a +blank, + +newline, carriage return, = +or ( (when the extglob shell option is enabled using +the shopt builtin). +
!n + +
+Refer to command line +n. + +
!-n + +
+Refer to the current command line minus +n. + +
!! + +
+Refer to the previous command. This is a synonym for `!-1'. +
!string + +
+Refer to the most recent command starting with +string. + +
!?string[?] + +
+Refer to the most recent command containing +string. + +The trailing ? may be omitted if +string + +is followed immediately by a newline. +
^string1^string2^ + +
+Quick substitution. Repeat the last command, replacing +string1 + +with +string2. + +Equivalent to +``!!:s/string1/string2/'' +(see Modifiers below). +
!# + +
+The entire command line typed so far. + +
+  +

Word Designators

+ +

+ +Word designators are used to select desired words from the event. +A +: + +separates the event specification from the word designator. +It may be omitted if the word designator begins with a +^, + +$, + +*, + +-, + +or +%. + +Words are numbered from the beginning of the line, +with the first word being denoted by 0 (zero). +Words are inserted into the current line separated by single spaces. +

+ + +

+
0 (zero) + +
+The zeroth word. For the shell, this is the command +word. +
n + +
+The nth word. +
^ + +
+The first argument. That is, word 1. +
$ + +
+The last argument. +
% + +
+The word matched by the most recent `?string?' search. +
x-y + +
+A range of words; `-y' abbreviates `0-y'. +
* + +
+All of the words but the zeroth. This is a synonym +for `1-$'. It is not an error to use +* + +if there is just one +word in the event; the empty string is returned in that case. +
x* + +
+Abbreviates x-$. +
x- + +
+Abbreviates x-$ like x*, but omits the last word. + +
+

+ +If a word designator is supplied without an event specification, the +previous command is used as the event. +  +

Modifiers

+ +

+ +After the optional word designator, there may appear a sequence of +one or more of the following modifiers, each preceded by a `:'. +

+ + +

+ +

+
h + +
+Remove a trailing file name component, leaving only the head. +
t + +
+Remove all leading file name components, leaving the tail. +
r + +
+Remove a trailing suffix of the form .xxx, leaving the +basename. +
e + +
+Remove all but the trailing suffix. +
p + +
+Print the new command but do not execute it. +
q + +
+Quote the substituted words, escaping further substitutions. +
x + +
+Quote the substituted words as with +q, + +but break into words at +blanks + +and newlines. +
s/old/new/ + +
+Substitute +new + +for the first occurrence of +old + +in the event line. Any delimiter can be used in place of /. The +final delimiter is optional if it is the last character of the +event line. The delimiter may be quoted in +old + +and +new + +with a single backslash. If & appears in +new, + +it is replaced by +old. + +A single backslash will quote the &. If +old + +is null, it is set to the last +old + +substituted, or, if no previous history substitutions took place, +the last +string + +in a +!?string[?] + +search. +
& + +
+Repeat the previous substitution. +
g + +
+Cause changes to be applied over the entire event line. This is +used in conjunction with `:s' (e.g., `:gs/old/new/') +or `:&'. If used with +`:s', any delimiter can be used +in place of /, and the final delimiter is optional +if it is the last character of the event line. +An a may be used as a synonym for g. +
G + +
+Apply the following `s' modifier once to each word in the event line. + +
+  +

SHELL BUILTIN COMMANDS

+ + + +

+ +Unless otherwise noted, each builtin command documented in this +section as accepting options preceded by +- + +accepts +-- + +to signify the end of the options. +For example, the :, true, false, and test builtins +do not accept options. +

+ +

+
: [arguments]
+ +No effect; the command does nothing beyond expanding +arguments + +and performing any specified +redirections. A zero exit code is returned. +
. filename [arguments]
+ +
source filename [arguments]
+ +Read and execute commands from +filename + +in the current +shell environment and return the exit status of the last command +executed from +filename. + +If +filename + +does not contain a slash, file names in +PATH + + +are used to find the directory containing +filename. + +The file searched for in +PATH + + +need not be executable. +When bash is not in posix mode, the current directory is +searched if no file is found in +PATH. + + +If the +sourcepath + +option to the +shopt + +builtin command is turned off, the +PATH + + +is not searched. +If any arguments are supplied, they become the positional +parameters when filename is executed. Otherwise the positional +parameters are unchanged. +The return status is the status of the last command exited within +the script (0 if no commands are executed), and false if +filename + +is not found or cannot be read. +
alias [-p] [name[=value] ...]
+Alias with no arguments or with the +-p + +option prints the list of aliases in the form +alias name=value on standard output. +When arguments are supplied, an alias is defined for +each name whose value is given. +A trailing space in value causes the next word to be +checked for alias substitution when the alias is expanded. +For each name in the argument list for which no value +is supplied, the name and value of the alias is printed. +Alias returns true unless a name is given for which +no alias has been defined. +
bg [jobspec ...]
+Resume each suspended job jobspec in the background, as if it +had been started with +&. + +If jobspec is not present, the shell's notion of the +current job is used. +bg + +jobspec + +returns 0 unless run when job control is disabled or, when run with +job control enabled, any specified jobspec was not found +or was started without job control. +
bind [-m keymap] [-lpsvPSV]
+ +
bind [-m keymap] [-q function] [-u function] [-r keyseq]
+
bind [-m keymap] -f filename
+
bind [-m keymap] -x keyseq:shell-command
+
bind [-m keymap] keyseq:function-name
+
bind readline-command
+ +Display current +readline + +key and function bindings, bind a key sequence to a +readline + +function or macro, or set a +readline + +variable. +Each non-option argument is a command as it would appear in +.inputrc, + +but each binding or command must be passed as a separate argument; +e.g., '"\C-x\C-r": re-read-init-file'. +Options, if supplied, have the following meanings: +
+ +
+
-m keymap + +
+Use +keymap + +as the keymap to be affected by the subsequent bindings. +Acceptable +keymap + +names are +emacs, emacs-standard, emacs-meta, emacs-ctlx, vi, +vi-move, vi-command, and +vi-insert. + +vi is equivalent to vi-command; emacs is +equivalent to emacs-standard. +
-l + +
+List the names of all readline functions. +
-p + +
+Display readline function names and bindings in such a way +that they can be re-read. +
-P + +
+List current readline function names and bindings. +
-v + +
+Display readline variable names and values in such a way that they +can be re-read. +
-V + +
+List current readline variable names and values. +
-s + +
+Display readline key sequences bound to macros and the strings +they output in such a way that they can be re-read. +
-S + +
+Display readline key sequences bound to macros and the strings +they output. +
-f filename + +
+Read key bindings from filename. +
-q function + +
+Query about which keys invoke the named function. +
-u function + +
+Unbind all keys bound to the named function. +
-r keyseq + +
+Remove any current binding for keyseq. +
-x keyseq:shell-command + +
+Cause shell-command to be executed whenever keyseq is +entered. + +
+

+ +The return value is 0 unless an unrecognized option is given or an +error occurred. +

+ +
break [n]
+Exit from within a +for, + +while, + +until, + +or +select + +loop. If n is specified, break n levels. +n + +must be >= 1. If +n + +is greater than the number of enclosing loops, all enclosing loops +are exited. The return value is 0 unless the shell is not executing +a loop when +break + +is executed. +
builtin shell-builtin [arguments]
+Execute the specified shell builtin, passing it +arguments, + +and return its exit status. +This is useful when defining a +function whose name is the same as a shell builtin, +retaining the functionality of the builtin within the function. +The cd builtin is commonly redefined this way. +The return status is false if +shell-builtin + +is not a shell builtin command. +
cd [-L|-P] [dir]
+Change the current directory to dir. The variable +HOME + + +is the +default +dir. + +The variable +CDPATH + + +defines the search path for the directory containing +dir. + +Alternative directory names in +CDPATH + + +are separated by a colon (:). A null directory name in +CDPATH + + +is the same as the current directory, i.e., ``.''. If +dir + +begins with a slash (/), +then +CDPATH + + +is not used. The +-P + +option says to use the physical directory structure instead of +following symbolic links (see also the +-P + +option to the +set + +builtin command); the +-L + +option forces symbolic links to be followed. An argument of +- + +is equivalent to +$OLDPWD. + + +If a non-empty directory name from CDPATH is used, or if +- is the first argument, and the directory change is +successful, the absolute pathname of the new working directory is +written to the standard output. +The return value is true if the directory was successfully changed; +false otherwise. +
caller [expr]
+Returns the context of any active subroutine call (a shell function or +a script executed with the . or source builtins. +Without expr, caller displays the line number and source +filename of the current subroutine call. +If a non-negative integer is supplied as expr, caller +displays the line number, subroutine name, and source file corresponding +to that position in the current execution call stack. This extra +information may be used, for example, to print a stack trace. The +current frame is frame 0. +The return value is 0 unless the shell is not executing a subroutine +call or expr does not correspond to a valid position in the +call stack. +
command [-pVv] command [arg ...]
+Run +command + +with +args + +suppressing the normal shell function lookup. Only builtin +commands or commands found in the +PATH + + +are executed. If the +-p + +option is given, the search for +command + +is performed using a default value for +PATH + +that is guaranteed to find all of the standard utilities. +If either the +-V + +or +-v + +option is supplied, a description of +command + +is printed. The +-v + +option causes a single word indicating the command or file name +used to invoke +command + +to be displayed; the +-V + +option produces a more verbose description. +If the +-V + +or +-v + +option is supplied, the exit status is 0 if +command + +was found, and 1 if not. If neither option is supplied and +an error occurred or +command + +cannot be found, the exit status is 127. Otherwise, the exit status of the +command + +builtin is the exit status of +command. + +
compgen [option] [word]
+Generate possible completion matches for word according to +the options, which may be any option accepted by the +complete + +builtin with the exception of -p and -r, and write +the matches to the standard output. +When using the -F or -C options, the various shell variables +set by the programmable completion facilities, while available, will not +have useful values. +

+The matches will be generated in the same way as if the programmable +completion code had generated them directly from a completion specification +with the same flags. +If word is specified, only those completions matching word +will be displayed. +

+The return value is true unless an invalid option is supplied, or no +matches were generated. +

complete [-abcdefgjksuv] [-o comp-option] [-A action] [-G globpat] [-W wordlist] [-P prefix] [-S suffix]
+
+ +[-X filterpat] [-F function] [-C command] name [name ...] + +
complete -pr [name ...]
+ +Specify how arguments to each name should be completed. +If the -p option is supplied, or if no options are supplied, +existing completion specifications are printed in a way that allows +them to be reused as input. +The -r option removes a completion specification for +each name, or, if no names are supplied, all +completion specifications. +

+The process of applying these completion specifications when word completion +is attempted is described above under Programmable Completion. +

+Other options, if specified, have the following meanings. +The arguments to the -G, -W, and -X options +(and, if necessary, the -P and -S options) +should be quoted to protect them from expansion before the +complete + +builtin is invoked. +

+ +
+
-o comp-option
+The comp-option controls several aspects of the compspec's behavior +beyond the simple generation of completions. +comp-option may be one of: +
+
+
bashdefault + +
+Perform the rest of the default bash completions if the compspec +generates no matches. +
default + +
+Use readline's default filename completion if the compspec generates +no matches. +
dirnames + +
+Perform directory name completion if the compspec generates no matches. +
filenames + +
+Tell readline that the compspec generates filenames, so it can perform any +filename-specific processing (like adding a slash to directory names or +suppressing trailing spaces). Intended to be used with shell functions. +
nospace + +
+Tell readline not to append a space (the default) to words completed at +the end of the line. +
plusdirs + +
+After any matches defined by the compspec are generated, +directory name completion is attempted and any +matches are added to the results of the other actions. +
+ +
-A action
+The action may be one of the following to generate a list of possible +completions: +
+
+
alias + +
+Alias names. May also be specified as -a. +
arrayvar + +
+Array variable names. +
binding + +
+Readline key binding names. +
builtin + +
+Names of shell builtin commands. May also be specified as -b. +
command + +

directory + +
+Directory names. May also be specified as -d. +
disabled + +
+Names of disabled shell builtins. +
enabled + +
+Names of enabled shell builtins. +
export + +
+Names of exported shell variables. May also be specified as -e. +
file + +
+File names. May also be specified as -f. +
function + +
+Names of shell functions. +
group + +
+Group names. May also be specified as -g. +
helptopic + +
+Help topics as accepted by the help builtin. +
hostname + +
+Hostnames, as taken from the file specified by the +HOSTFILE + + +shell variable. +
job + +
+Job names, if job control is active. May also be specified as -j. +
keyword + +
+Shell reserved words. May also be specified as -k. +
running + +
+Names of running jobs, if job control is active. +
service + +
+Service names. May also be specified as -s. +
setopt + +
+Valid arguments for the -o option to the set builtin. +
shopt + +
+Shell option names as accepted by the shopt builtin. +
signal + +
+Signal names. +
stopped + +
+Names of stopped jobs, if job control is active. +
user + +
+User names. May also be specified as -u. +
variable + +
+Names of all shell variables. May also be specified as -v. +
+ +
-G globpat
+The filename expansion pattern globpat is expanded to generate +the possible completions. +
-W wordlist
+The wordlist is split using the characters in the +IFS + + +special variable as delimiters, and each resultant word is expanded. +The possible completions are the members of the resultant list which +match the word being completed. +
-C command
+command is executed in a subshell environment, and its output is +used as the possible completions. +
-F function
+The shell function function is executed in the current shell +environment. +When it finishes, the possible completions are retrieved from the value +of the +COMPREPLY + + +array variable. +
-X filterpat
+filterpat is a pattern as used for filename expansion. +It is applied to the list of possible completions generated by the +preceding options and arguments, and each completion matching +filterpat is removed from the list. +A leading ! in filterpat negates the pattern; in this +case, any completion not matching filterpat is removed. +
-P prefix
+prefix is added at the beginning of each possible completion +after all other options have been applied. +
-S suffix
+suffix is appended to each possible completion +after all other options have been applied. + +
+

+ +The return value is true unless an invalid option is supplied, an option +other than -p or -r is supplied without a name +argument, an attempt is made to remove a completion specification for +a name for which no specification exists, or +an error occurs adding a completion specification. +

+ +
continue [n]
+Resume the next iteration of the enclosing +for, + +while, + +until, + +or +select + +loop. +If +n + +is specified, resume at the nth enclosing loop. +n + +must be >= 1. If +n + +is greater than the number of enclosing loops, the last enclosing loop +(the ``top-level'' loop) is resumed. The return value is 0 unless the +shell is not executing a loop when +continue + +is executed. +
declare [-afFirtx] [-p] [name[=value] ...]
+ +
typeset [-afFirtx] [-p] [name[=value] ...]
+ +Declare variables and/or give them attributes. +If no names are given then display the values of variables. +The +-p + +option will display the attributes and values of each +name. + +When +-p + +is used, additional options are ignored. +The +-F + +option inhibits the display of function definitions; only the +function name and attributes are printed. +If the extdebug shell option is enabled using shopt, +the source file name and line number where the function is defined +are displayed as well. The +-F + +option implies +-f. + +The following options can +be used to restrict output to variables with the specified attribute or +to give variables attributes: +
+ +
+
-a + +
+Each name is an array variable (see +Arrays + +above). +
-f + +
+Use function names only. +
-i + +
+The variable is treated as an integer; arithmetic evaluation (see +ARITHMETIC EVALUATION ) + + +is performed when the variable is assigned a value. +
-r + +
+Make names readonly. These names cannot then be assigned values +by subsequent assignment statements or unset. +
-t + +
+Give each name the trace attribute. +Traced functions inherit the DEBUG and RETURN traps from +the calling shell. +The trace attribute has no special meaning for variables. +
-x + +
+Mark names for export to subsequent commands via the environment. + +
+

+ +Using `+' instead of `-' +turns off the attribute instead, with the exception that +a +may not be used to destroy an array variable. When used in a function, +makes each +name local, as with the +local + +command. +If a variable name is followed by =value, the value of +the variable is set to value. +The return value is 0 unless an invalid option is encountered, +an attempt is made to define a function using + +-f foo=bar, +an attempt is made to assign a value to a readonly variable, +an attempt is made to assign a value to an array variable without +using the compound assignment syntax (see +Arrays + +above), one of the names is not a valid shell variable name, +an attempt is made to turn off readonly status for a readonly variable, +an attempt is made to turn off array status for an array variable, +or an attempt is made to display a non-existent function with -f. +

+ +
dirs [-clpv] [+n] [-n] + +
+Without options, displays the list of currently remembered directories. +The default display is on a single line with directory names separated +by spaces. +Directories are added to the list with the +pushd + +command; the +popd + +command removes entries from the list. +
+ +
+
+n
+Displays the nth entry counting from the left of the list +shown by +dirs + +when invoked without options, starting with zero. +
-n
+Displays the nth entry counting from the right of the list +shown by +dirs + +when invoked without options, starting with zero. +
-c + +
+Clears the directory stack by deleting all of the entries. +
-l + +
+Produces a longer listing; the default listing format uses a +tilde to denote the home directory. +
-p + +
+Print the directory stack with one entry per line. +
-v + +
+Print the directory stack with one entry per line, +prefixing each entry with its index in the stack. + +
+

+ +The return value is 0 unless an +invalid option is supplied or n indexes beyond the end +of the directory stack. +

+ +
disown [-ar] [-h] [jobspec ...]
+Without options, each +jobspec + +is removed from the table of active jobs. +If the -h option is given, each +jobspec + +is not removed from the table, but is marked so that +SIGHUP + + +is not sent to the job if the shell receives a +SIGHUP. + + +If no +jobspec + +is present, and neither the +-a + +nor the +-r + +option is supplied, the current job is used. +If no +jobspec + +is supplied, the +-a + +option means to remove or mark all jobs; the +-r + +option without a +jobspec + +argument restricts operation to running jobs. +The return value is 0 unless a +jobspec + +does not specify a valid job. +
echo [-neE] [arg ...]
+Output the args, separated by spaces, followed by a newline. +The return status is always 0. +If -n is specified, the trailing newline is +suppressed. If the -e option is given, interpretation of +the following backslash-escaped characters is enabled. The +-E + +option disables the interpretation of these escape characters, +even on systems where they are interpreted by default. +The xpg_echo shell option may be used to +dynamically determine whether or not echo expands these +escape characters by default. +echo + +does not interpret -- to mean the end of options. +echo + +interprets the following escape sequences: +
+ +
+
\a + +
+alert (bell) +
\b + +
+backspace +
\c + +
+suppress trailing newline +
\e + +
+an escape character +
\f + +
+form feed +
\n + +
+new line +
\r + +
+carriage return +
\t + +
+horizontal tab +
\v + +
+vertical tab +
\\ + +
+backslash +
\0nnn + +
+the eight-bit character whose value is the octal value nnn +(zero to three octal digits) +
\nnn + +
+the eight-bit character whose value is the octal value nnn +(one to three octal digits) +
\xHH + +
+the eight-bit character whose value is the hexadecimal value HH +(one or two hex digits) + +
+ +
enable [-adnps] [-f filename] [name ...]
+Enable and disable builtin shell commands. +Disabling a builtin allows a disk command which has the same name +as a shell builtin to be executed without specifying a full pathname, +even though the shell normally searches for builtins before disk commands. +If -n is used, each name +is disabled; otherwise, +names are enabled. For example, to use the +test + +binary found via the +PATH + + +instead of the shell builtin version, run +enable -n test. + +The +-f + +option means to load the new builtin command +name + +from shared object +filename, + +on systems that support dynamic loading. The +-d + +option will delete a builtin previously loaded with +-f. + +If no name arguments are given, or if the +-p + +option is supplied, a list of shell builtins is printed. +With no other option arguments, the list consists of all enabled +shell builtins. +If -n is supplied, only disabled builtins are printed. +If -a is supplied, the list printed includes all builtins, with an +indication of whether or not each is enabled. +If -s is supplied, the output is restricted to the POSIX +special builtins. +The return value is 0 unless a +name + +is not a shell builtin or there is an error loading a new builtin +from a shared object. +
eval [arg ...]
+The args are read and concatenated together into a single +command. This command is then read and executed by the shell, and +its exit status is returned as the value of +eval. + +If there are no +args, + +or only null arguments, +eval + +returns 0. +
exec [-cl] [-a name] [command [arguments]]
+If +command + +is specified, it replaces the shell. +No new process is created. The +arguments + +become the arguments to command. +If the +-l + +option is supplied, +the shell places a dash at the beginning of the zeroth arg passed to +command. + +This is what +login(1) + +does. The +-c + +option causes +command + +to be executed with an empty environment. If +-a + +is supplied, the shell passes +name + +as the zeroth argument to the executed command. If +command + +cannot be executed for some reason, a non-interactive shell exits, +unless the shell option +execfail + +is enabled, in which case it returns failure. +An interactive shell returns failure if the file cannot be executed. +If +command + +is not specified, any redirections take effect in the current shell, +and the return status is 0. If there is a redirection error, the +return status is 1. +
exit [n]
+Cause the shell to exit +with a status of n. If +n + +is omitted, the exit status +is that of the last command executed. +A trap on +EXIT + + +is executed before the shell terminates. +
export [-fn] [name[=word]] ...
+ +
export -p + +
+ +The supplied +names + +are marked for automatic export to the environment of +subsequently executed commands. If the +-f + +option is given, +the +names + +refer to functions. +If no +names + +are given, or if the +-p + +option is supplied, a list +of all names that are exported in this shell is printed. +The +-n + +option causes the export property to be removed from each +name. +If a variable name is followed by =word, the value of +the variable is set to word. +export + +returns an exit status of 0 unless an invalid option is +encountered, +one of the names is not a valid shell variable name, or +-f + +is supplied with a +name + +that is not a function. +
fc [-e ename] [-nlr] [first] [last]
+ +
fc -s [pat=rep] [cmd]
+ +Fix Command. In the first form, a range of commands from +first + +to +last + +is selected from the history list. +First + +and +last + +may be specified as a string (to locate the last command beginning +with that string) or as a number (an index into the history list, +where a negative number is used as an offset from the current +command number). If +last + +is not specified it is set to +the current command for listing (so that + +fc -l -10 +prints the last 10 commands) and to +first + +otherwise. +If +first + +is not specified it is set to the previous +command for editing and -16 for listing. +

+The +-n + +option suppresses +the command numbers when listing. The +-r + +option reverses the order of +the commands. If the +-l + +option is given, +the commands are listed on +standard output. Otherwise, the editor given by +ename + +is invoked +on a file containing those commands. If +ename + +is not given, the +value of the +FCEDIT + + +variable is used, and +the value of +EDITOR + + +if +FCEDIT + + +is not set. If neither variable is set, + +vi + +is used. When editing is complete, the edited commands are +echoed and executed. +

+In the second form, command is re-executed after each instance +of pat is replaced by rep. +A useful alias to use with this is + +r='fc -s', +so that typing + +r cc +runs the last command beginning with + +cc +and typing + +r +re-executes the last command. +

+If the first form is used, the return value is 0 unless an invalid +option is encountered or +first + +or +last + +specify history lines out of range. +If the +-e + +option is supplied, the return value is the value of the last +command executed or failure if an error occurs with the temporary +file of commands. If the second form is used, the return status +is that of the command re-executed, unless +cmd + +does not specify a valid history line, in which case +fc + +returns failure. +

fg [jobspec]
+Resume +jobspec + +in the foreground, and make it the current job. +If +jobspec + +is not present, the shell's notion of the current job is used. +The return value is that of the command placed into the foreground, +or failure if run when job control is disabled or, when run with +job control enabled, if +jobspec + +does not specify a valid job or +jobspec + +specifies a job that was started without job control. +
getopts optstring name [args]
+getopts + +is used by shell procedures to parse positional parameters. +optstring + +contains the option characters to be recognized; if a character +is followed by a colon, the option is expected to have an +argument, which should be separated from it by white space. +The colon and question mark characters may not be used as +option characters. +Each time it is invoked, +getopts + +places the next option in the shell variable +name, + +initializing +name + +if it does not exist, +and the index of the next argument to be processed into the +variable +OPTIND. + + +OPTIND + + +is initialized to 1 each time the shell or a shell script +is invoked. When an option requires an argument, +getopts + +places that argument into the variable +OPTARG. + + +The shell does not reset +OPTIND + + +automatically; it must be manually reset between multiple +calls to +getopts + +within the same shell invocation if a new set of parameters +is to be used. +

+When the end of options is encountered, getopts exits with a +return value greater than zero. +OPTIND is set to the index of the first non-option argument, +and name is set to ?. +

+getopts + +normally parses the positional parameters, but if more arguments are +given in +args, + +getopts + +parses those instead. +

+getopts + +can report errors in two ways. If the first character of +optstring + +is a colon, +silent + +error reporting is used. In normal operation diagnostic messages +are printed when invalid options or missing option arguments are +encountered. +If the variable +OPTERR + + +is set to 0, no error messages will be displayed, even if the first +character of +optstring + +is not a colon. +

+If an invalid option is seen, +getopts + +places ? into +name + +and, if not silent, +prints an error message and unsets +OPTARG. + + +If +getopts + +is silent, +the option character found is placed in +OPTARG + + +and no diagnostic message is printed. +

+If a required argument is not found, and +getopts + +is not silent, +a question mark (?) is placed in +name, + +OPTARG + + +is unset, and a diagnostic message is printed. +If +getopts + +is silent, then a colon (:) is placed in +name + +and +OPTARG + + +is set to the option character found. +

+getopts + +returns true if an option, specified or unspecified, is found. +It returns false if the end of options is encountered or an +error occurs. +

hash [-lr] [-p filename] [-dt] [name]
+For each +name, + +the full file name of the command is determined by searching +the directories in +$PATH + +and remembered. +If the +-p + +option is supplied, no path search is performed, and +filename + +is used as the full file name of the command. +The +-r + +option causes the shell to forget all +remembered locations. +The +-d + +option causes the shell to forget the remembered location of each name. +If the +-t + +option is supplied, the full pathname to which each name corresponds +is printed. If multiple name arguments are supplied with -t, +the name is printed before the hashed full pathname. +The +-l + +option causes output to be displayed in a format that may be reused as input. +If no arguments are given, or if only -l is supplied, +information about remembered commands is printed. +The return status is true unless a +name + +is not found or an invalid option is supplied. +
help [-s] [pattern]
+Display helpful information about builtin commands. If +pattern + +is specified, +help + +gives detailed help on all commands matching +pattern; + +otherwise help for all the builtins and shell control structures +is printed. +The -s option restricts the information displayed to a short +usage synopsis. +The return status is 0 unless no command matches +pattern. + +
history [n]
+ +
history -c
+
history -d offset
+
history -anrw [filename]
+
history -p arg [arg ...]
+
history -s arg [arg ...]
+ +With no options, display the command +history list with line numbers. Lines listed +with a +* + +have been modified. An argument of +n + +lists only the last +n + +lines. +If the shell variable HISTTIMEFORMAT is set and not null, +it is used as a format string for strftime(3) to display +the time stamp associated with each displayed history entry. +No intervening blank is printed between the formatted time stamp +and the history line. +If filename is supplied, it is used as the +name of the history file; if not, the value of +HISTFILE + + +is used. Options, if supplied, have the following meanings: +
+ +
+
-c + +
+Clear the history list by deleting all the entries. +
-d offset
+Delete the history entry at position offset. +
-a + +
+Append the ``new'' history lines (history lines entered since the +beginning of the current bash session) to the history file. +
-n + +
+Read the history lines not already read from the history +file into the current history list. These are lines +appended to the history file since the beginning of the +current bash session. +
-r + +
+Read the contents of the history file +and use them as the current history. +
-w + +
+Write the current history to the history file, overwriting the +history file's contents. +
-p + +
+Perform history substitution on the following args and display +the result on the standard output. +Does not store the results in the history list. +Each arg must be quoted to disable normal history expansion. +
-s + +
+Store the +args + +in the history list as a single entry. The last command in the +history list is removed before the +args + +are added. + +
+

+ +If the HISTTIMEFORMAT is set, the time stamp information +associated with each history entry is written to the history file. +The return value is 0 unless an invalid option is encountered, an +error occurs while reading or writing the history file, an invalid +offset is supplied as an argument to -d, or the +history expansion supplied as an argument to -p fails. +

+ +
jobs [-lnprs] [ jobspec ... ]
+ +
jobs -x command [ args ... ]
+ +The first form lists the active jobs. The options have the following +meanings: +
+ +
+
-l + +
+List process IDs +in addition to the normal information. +
-p + +
+List only the process ID of the job's process group +leader. +
-n + +
+Display information only about jobs that have changed status since +the user was last notified of their status. +
-r + +
+Restrict output to running jobs. +
-s + +
+Restrict output to stopped jobs. + +
+

+ +If +jobspec + +is given, output is restricted to information about that job. +The return status is 0 unless an invalid option is encountered +or an invalid +jobspec + +is supplied. +

+ +If the +-x + +option is supplied, +jobs + +replaces any +jobspec + +found in +command + +or +args + +with the corresponding process group ID, and executes +command + +passing it +args, + +returning its exit status. +

+ +
kill [-s sigspec | -n signum | -sigspec] [pid | jobspec] ...
+ +
kill -l [sigspec | exit_status]
+ +Send the signal named by +sigspec + +or +signum + +to the processes named by +pid + +or +jobspec. + +sigspec + +is either a case-insensitive signal name such as +SIGKILL + + +(with or without the +SIG + + +prefix) or a signal number; +signum + +is a signal number. +If +sigspec + +is not present, then +SIGTERM + + +is assumed. +An argument of +-l + +lists the signal names. +If any arguments are supplied when +-l + +is given, the names of the signals corresponding to the arguments are +listed, and the return status is 0. +The exit_status argument to +-l + +is a number specifying either a signal number or the exit status of +a process terminated by a signal. +kill + +returns true if at least one signal was successfully sent, or false +if an error occurs or an invalid option is encountered. +
let arg [arg ...]
+Each +arg + +is an arithmetic expression to be evaluated (see +ARITHMETIC EVALUATION). + + +If the last +arg + +evaluates to 0, +let + +returns 1; 0 is returned otherwise. +
local [option] [name[=value] ...]
+For each argument, a local variable named +name + +is created, and assigned +value. + +The option can be any of the options accepted by declare. +When +local + +is used within a function, it causes the variable +name + +to have a visible scope restricted to that function and its children. +With no operands, +local + +writes a list of local variables to the standard output. It is +an error to use +local + +when not within a function. The return status is 0 unless +local + +is used outside a function, an invalid +name + +is supplied, or +name is a readonly variable. +
logout + +
+Exit a login shell. +
popd [-n] [+n] [-n]
+Removes entries from the directory stack. With no arguments, +removes the top directory from the stack, and performs a +cd + +to the new top directory. +Arguments, if supplied, have the following meanings: +
+ +
+
+n
+Removes the nth entry counting from the left of the list +shown by +dirs, + +starting with zero. For example: + +popd +0 +removes the first directory, + +popd +1 +the second. +
-n
+Removes the nth entry counting from the right of the list +shown by +dirs, + +starting with zero. For example: + +popd -0 +removes the last directory, + +popd -1 +the next to last. +
-n + +
+Suppresses the normal change of directory when removing directories +from the stack, so that only the stack is manipulated. + +
+

+ +If the +popd + +command is successful, a +dirs + +is performed as well, and the return status is 0. +popd + +returns false if an invalid option is encountered, the directory stack +is empty, a non-existent directory stack entry is specified, or the +directory change fails. +

+ +
printf [-v var] format [arguments]
+Write the formatted arguments to the standard output under the +control of the format. +The format is a character string which contains three types of objects: +plain characters, which are simply copied to standard output, character +escape sequences, which are converted and copied to the standard output, and +format specifications, each of which causes printing of the next successive +argument. +In addition to the standard printf(1) formats, %b causes +printf to expand backslash escape sequences in the corresponding +argument (except that \c terminates output, backslashes in +\aq, \", and \? are not removed, and octal escapes +beginning with \0 may contain up to four digits), +and %q causes printf to output the corresponding +argument in a format that can be reused as shell input. +

+The -v option causes the output to be assigned to the variable +var rather than being printed to the standard output. +

+The format is reused as necessary to consume all of the arguments. +If the format requires more arguments than are supplied, the +extra format specifications behave as if a zero value or null string, as +appropriate, had been supplied. The return value is zero on success, +non-zero on failure. +

pushd [-n] [dir]
+ +
pushd [-n] [+n] [-n]
+ +Adds a directory to the top of the directory stack, or rotates +the stack, making the new top of the stack the current working +directory. With no arguments, exchanges the top two directories +and returns 0, unless the directory stack is empty. +Arguments, if supplied, have the following meanings: +
+ +
+
+n
+Rotates the stack so that the nth directory +(counting from the left of the list shown by +dirs, + +starting with zero) +is at the top. +
-n
+Rotates the stack so that the nth directory +(counting from the right of the list shown by +dirs, + +starting with zero) is at the top. +
-n + +
+Suppresses the normal change of directory when adding directories +to the stack, so that only the stack is manipulated. +
dir + +
+Adds +dir + +to the directory stack at the top, making it the +new current working directory. + +
+

+ +If the +pushd + +command is successful, a +dirs + +is performed as well. +If the first form is used, +pushd + +returns 0 unless the cd to +dir + +fails. With the second form, +pushd + +returns 0 unless the directory stack is empty, +a non-existent directory stack element is specified, +or the directory change to the specified new current directory +fails. +

+ +
pwd [-LP]
+Print the absolute pathname of the current working directory. +The pathname printed contains no symbolic links if the +-P + +option is supplied or the +-o physical + +option to the +set + +builtin command is enabled. +If the +-L + +option is used, the pathname printed may contain symbolic links. +The return status is 0 unless an error occurs while +reading the name of the current directory or an +invalid option is supplied. +
read [-ers] [-u fd] [-t timeout] [-a aname] [-p prompt] [-n nchars] [-d delim] [name ...]
+One line is read from the standard input, or from the file descriptor +fd supplied as an argument to the -u option, and the first word +is assigned to the first +name, + +the second word to the second +name, + +and so on, with leftover words and their intervening separators assigned +to the last +name. + +If there are fewer words read from the input stream than names, +the remaining names are assigned empty values. +The characters in +IFS + + +are used to split the line into words. +The backslash character (\) may be used to remove any special +meaning for the next character read and for line continuation. +Options, if supplied, have the following meanings: +
+ +
+
-a aname + +
+The words are assigned to sequential indices +of the array variable +aname, + +starting at 0. +aname + +is unset before any new values are assigned. +Other name arguments are ignored. +
-d delim + +
+The first character of delim is used to terminate the input line, +rather than newline. +
-e + +
+If the standard input +is coming from a terminal, +readline + +(see +READLINE + + +above) is used to obtain the line. +
-n nchars + +
+read returns after reading nchars characters rather than +waiting for a complete line of input. +
-p prompt + +
+Display prompt on standard error, without a +trailing newline, before attempting to read any input. The prompt +is displayed only if input is coming from a terminal. +
-r + +
+Backslash does not act as an escape character. +The backslash is considered to be part of the line. +In particular, a backslash-newline pair may not be used as a line +continuation. +
-s + +
+Silent mode. If input is coming from a terminal, characters are +not echoed. +
-t timeout + +
+Cause read to time out and return failure if a complete line of +input is not read within timeout seconds. +This option has no effect if read is not reading input from the +terminal or a pipe. +
-u fd + +
+Read input from file descriptor fd. + +
+

+ +If no +names + +are supplied, the line read is assigned to the variable +REPLY. + + +The return code is zero, unless end-of-file is encountered, read +times out, or an invalid file descriptor is supplied as the argument to +-u. +

+ +
readonly [-apf] [name[=word] ...]
+ +The given +names are marked readonly; the values of these +names + +may not be changed by subsequent assignment. +If the +-f + +option is supplied, the functions corresponding to the +names are so +marked. +The +-a + +option restricts the variables to arrays. +If no +name + +arguments are given, or if the +-p + +option is supplied, a list of all readonly names is printed. +The +-p + +option causes output to be displayed in a format that +may be reused as input. +If a variable name is followed by =word, the value of +the variable is set to word. +The return status is 0 unless an invalid option is encountered, +one of the +names + +is not a valid shell variable name, or +-f + +is supplied with a +name + +that is not a function. +
return [n]
+Causes a function to exit with the return value specified by +n. + +If +n + +is omitted, the return status is that of the last command +executed in the function body. If used outside a function, +but during execution of a script by the +. + +(source) command, it causes the shell to stop executing +that script and return either +n + +or the exit status of the last command executed within the +script as the exit status of the script. If used outside a +function and not during execution of a script by ., +the return status is false. +Any command associated with the RETURN trap is executed +before execution resumes after the function or script. +
set [--abefhkmnptuvxBCHP] [-o option] [arg ...]
+Without options, the name and value of each shell variable are displayed +in a format that can be reused as input +for setting or resetting the currently-set variables. +Read-only variables cannot be reset. +In posix mode, only shell variables are listed. +The output is sorted according to the current locale. +When options are specified, they set or unset shell attributes. +Any arguments remaining after the options are processed are treated +as values for the positional parameters and are assigned, in order, to +$1, + +$2, + +... + +$n. + +Options, if specified, have the following meanings: +
+ +
+
-a + +
+Automatically mark variables and functions which are modified or +created for export to the environment of subsequent commands. +
-b + +
+Report the status of terminated background jobs +immediately, rather than before the next primary prompt. This is +effective only when job control is enabled. +
-e + +
+Exit immediately if a simple command (see +SHELL GRAMMAR + + +above) exits with a non-zero status. +The shell does not exit if the +command that fails is part of the command list immediately following a +while + +or +until + +keyword, +part of the test in an +if + +statement, part of a +&& + +or +|| + +list, or if the command's return value is +being inverted via +!. + +A trap on ERR, if set, is executed before the shell exits. +
-f + +
+Disable pathname expansion. +
-h + +
+Remember the location of commands as they are looked up for execution. +This is enabled by default. +
-k + +
+All arguments in the form of assignment statements +are placed in the environment for a command, not just +those that precede the command name. +
-m + +
+Monitor mode. Job control is enabled. This option is on +by default for interactive shells on systems that support +it (see +JOB CONTROL + + +above). Background processes run in a separate process +group and a line containing their exit status is printed +upon their completion. +
-n + +
+Read commands but do not execute them. This may be used to +check a shell script for syntax errors. This is ignored by +interactive shells. +
-o option-name + +
+The option-name can be one of the following: +
+
+
allexport + +
+Same as +-a. + +
braceexpand + +
+Same as +-B. + +
emacs + +
+Use an emacs-style command line editing interface. This is enabled +by default when the shell is interactive, unless the shell is started +with the +--noediting + +option. +
errtrace + +
+Same as +-E. + +
functrace + +
+Same as +-T. + +
errexit + +
+Same as +-e. + +
hashall + +
+Same as +-h. + +
histexpand + +
+Same as +-H. + +
history + +
+Enable command history, as described above under +HISTORY. + + +This option is on by default in interactive shells. +
ignoreeof + +
+The effect is as if the shell command +IGNOREEOF=10 + +had been executed +(see +Shell Variables + +above). +
keyword + +
+Same as +-k. + +
monitor + +
+Same as +-m. + +
noclobber + +
+Same as +-C. + +

onecmd + +
+Same as +-t. + +
physical + +
+Same as +-P. + +
pipefail + +
+If set, the return value of a pipeline is the value of the last +(rightmost) command to exit with a non-zero status, or zero if all +commands in the pipeline exit successfully. +This option is disabled by default. +
posix + +
+Change the behavior of +bash + +where the default operation differs +from the POSIX standard to match the standard (posix mode). +
privileged + +
+Same as +-p. + +
verbose + +
+Same as +-v. + +
vi + +
+Use a vi-style command line editing interface. +
xtrace + +
+Same as +-x. + +

+

+

+ +If +-o + +is supplied with no option-name, the values of the current options are +printed. +If ++o + +is supplied with no option-name, a series of +set + +commands to recreate the current option settings is displayed on +the standard output. +

+ +
-p + +
+Turn on +privileged + +mode. In this mode, the +$ENV + + +and +$BASH_ENV + + +files are not processed, shell functions are not inherited from the +environment, and the +SHELLOPTS + + +variable, if it appears in the environment, is ignored. +If the shell is started with the effective user (group) id not equal to the +real user (group) id, and the -p option is not supplied, these actions +are taken and the effective user id is set to the real user id. +If the -p option is supplied at startup, the effective user id is +not reset. +Turning this option off causes the effective user +and group ids to be set to the real user and group ids. +
-t + +
+Exit after reading and executing one command. +
-u + +
+Treat unset variables as an error when performing +parameter expansion. If expansion is attempted on an +unset variable, the shell prints an error message, and, +if not interactive, exits with a non-zero status. +
-v + +
+Print shell input lines as they are read. +
-x + +
+After expanding each simple command, +for command, case command, select command, or +arithmetic for command, display the expanded value of +PS4, + + +followed by the command and its expanded arguments +or associated word list. +
-B + +
+The shell performs brace expansion (see +Brace Expansion + +above). This is on by default. +
-C + +
+If set, +bash + +does not overwrite an existing file with the +>, + +>&, + +and +<> + +redirection operators. This may be overridden when +creating output files by using the redirection operator +>| + +instead of +>. + +
-E + +
+If set, any trap on ERR is inherited by shell functions, command +substitutions, and commands executed in a subshell environment. +The ERR trap is normally not inherited in such cases. +
-H + +
+Enable +! + +style history substitution. This option is on by +default when the shell is interactive. +
-P + +
+If set, the shell does not follow symbolic links when executing +commands such as +cd + +that change the current working directory. It uses the +physical directory structure instead. By default, +bash + +follows the logical chain of directories when performing commands +which change the current directory. +
-T + +
+If set, any traps on DEBUG and RETURN are inherited by shell +functions, command substitutions, and commands executed in a +subshell environment. +The DEBUG and RETURN traps are normally not inherited +in such cases. +
-- + +
+If no arguments follow this option, then the positional parameters are +unset. Otherwise, the positional parameters are set to the +args, even if some of them begin with a +-. + +
- + +
+Signal the end of options, cause all remaining args to be +assigned to the positional parameters. The +-x + +and +-v + +options are turned off. +If there are no args, +the positional parameters remain unchanged. + +
+

+ +The options are off by default unless otherwise noted. +Using + rather than - causes these options to be turned off. +The options can also be specified as arguments to an invocation of +the shell. +The current set of options may be found in +$-. + +The return status is always true unless an invalid option is encountered. +

+ +
shift [n]
+The positional parameters from n+1 ... are renamed to +$1 + +.... + +Parameters represented by the numbers $# +down to $#-n+1 are unset. +n + +must be a non-negative number less than or equal to $#. +If +n + +is 0, no parameters are changed. +If +n + +is not given, it is assumed to be 1. +If +n + +is greater than $#, the positional parameters are not changed. +The return status is greater than zero if +n + +is greater than +$# + +or less than zero; otherwise 0. +
shopt [-pqsu] [-o] [optname ...]
+Toggle the values of variables controlling optional shell behavior. +With no options, or with the +-p + +option, a list of all settable options is displayed, with +an indication of whether or not each is set. +The -p option causes output to be displayed in a form that +may be reused as input. +Other options have the following meanings: +
+ +
+
-s + +
+Enable (set) each optname. +
-u + +
+Disable (unset) each optname. +
-q + +
+Suppresses normal output (quiet mode); the return status indicates +whether the optname is set or unset. +If multiple optname arguments are given with +-q, + +the return status is zero if all optnames are enabled; non-zero +otherwise. +
-o + +
+Restricts the values of optname to be those defined for the +-o + +option to the +set + +builtin. + +
+

+ +If either +-s + +or +-u + +is used with no optname arguments, the display is limited to +those options which are set or unset, respectively. +Unless otherwise noted, the shopt options are disabled (unset) +by default. +

+ +The return status when listing options is zero if all optnames +are enabled, non-zero otherwise. When setting or unsetting options, +the return status is zero unless an optname is not a valid shell +option. +

+ +The list of shopt options is: +

+ + + +

+
cdable_vars + +
+If set, an argument to the +cd + +builtin command that +is not a directory is assumed to be the name of a variable whose +value is the directory to change to. +
cdspell + +
+If set, minor errors in the spelling of a directory component in a +cd + +command will be corrected. +The errors checked for are transposed characters, +a missing character, and one character too many. +If a correction is found, the corrected file name is printed, +and the command proceeds. +This option is only used by interactive shells. +
checkhash + +
+If set, bash checks that a command found in the hash +table exists before trying to execute it. If a hashed command no +longer exists, a normal path search is performed. +
checkwinsize + +
+If set, bash checks the window size after each command +and, if necessary, updates the values of +LINES + + +and +COLUMNS. + + +
cmdhist + +
+If set, +bash + +attempts to save all lines of a multiple-line +command in the same history entry. This allows +easy re-editing of multi-line commands. +
dotglob + +
+If set, +bash + +includes filenames beginning with a `.' in the results of pathname +expansion. +
execfail + +
+If set, a non-interactive shell will not exit if +it cannot execute the file specified as an argument to the +exec + +builtin command. An interactive shell does not exit if +exec + +fails. +
expand_aliases + +
+If set, aliases are expanded as described above under +ALIASES. + + +This option is enabled by default for interactive shells. +
extdebug + +
+If set, behavior intended for use by debuggers is enabled: +
+
+
1. + +
+The -F option to the declare builtin displays the source +file name and line number corresponding to each function name supplied +as an argument. +
2. + +
+If the command run by the DEBUG trap returns a non-zero value, the +next command is skipped and not executed. +
3. + +
+If the command run by the DEBUG trap returns a value of 2, and the +shell is executing in a subroutine (a shell function or a shell script +executed by the . or source builtins), a call to +return is simulated. +
4. + +
+BASH_ARGC and BASH_ARGV are updated as described in their +descriptions above. +
5. + +
+Function tracing is enabled: command substitution, shell functions, and +subshells invoked with ( command ) inherit the +DEBUG and RETURN traps. +
6. + +
+Error tracing is enabled: command substitution, shell functions, and +subshells invoked with ( command ) inherit the +ERROR trap. +
+ +
extglob + +
+If set, the extended pattern matching features described above under +Pathname Expansion are enabled. +
extquote + +
+If set, $aqstringaq and $"string" quoting is +performed within ${parameter} expansions +enclosed in double quotes. This option is enabled by default. +
failglob + +
+If set, patterns which fail to match filenames during pathname expansion +result in an expansion error. +
force_fignore + +
+If set, the suffixes specified by the FIGNORE shell variable +cause words to be ignored when performing word completion even if +the ignored words are the only possible completions. +See +SHELL VARIABLES +above for a description of FIGNORE. +This option is enabled by default. +
gnu_errfmt + +
+If set, shell error messages are written in the standard GNU error +message format. +
histappend + +
+If set, the history list is appended to the file named by the value +of the +HISTFILE + +variable when the shell exits, rather than overwriting the file. +
histreedit + +
+If set, and +readline + +is being used, a user is given the opportunity to re-edit a +failed history substitution. +
histverify + +
+If set, and +readline + +is being used, the results of history substitution are not immediately +passed to the shell parser. Instead, the resulting line is loaded into +the readline editing buffer, allowing further modification. +
hostcomplete + +
+If set, and +readline + +is being used, bash will attempt to perform hostname completion when a +word containing a @ is being completed (see +Completing + +under +READLINE + + +above). +This is enabled by default. +
huponexit + +
+If set, bash will send +SIGHUP + + +to all jobs when an interactive login shell exits. +
interactive_comments + +
+If set, allow a word beginning with +# + +to cause that word and all remaining characters on that +line to be ignored in an interactive shell (see +COMMENTS + + +above). This option is enabled by default. +
lithist + +
+If set, and the +cmdhist + +option is enabled, multi-line commands are saved to the history with +embedded newlines rather than using semicolon separators where possible. +
login_shell + +
+The shell sets this option if it is started as a login shell (see +INVOCATION + + +above). +The value may not be changed. +
mailwarn + +
+If set, and a file that bash is checking for mail has been +accessed since the last time it was checked, the message ``The mail in +mailfile has been read'' is displayed. +
no_empty_cmd_completion + +
+If set, and +readline + +is being used, +bash + +will not attempt to search the PATH for possible completions when +completion is attempted on an empty line. +
nocaseglob + +
+If set, +bash + +matches filenames in a case-insensitive fashion when performing pathname +expansion (see +Pathname Expansion + +above). +
nocasematch + +
+If set, +bash + +matches patterns in a case-insensitive fashion when performing matching +while executing case or [[ conditional commands. +
nullglob + +
+If set, +bash + +allows patterns which match no +files (see +Pathname Expansion + +above) +to expand to a null string, rather than themselves. +
progcomp + +
+If set, the programmable completion facilities (see +Programmable Completion above) are enabled. +This option is enabled by default. +
promptvars + +
+If set, prompt strings undergo +parameter expansion, command substitution, arithmetic +expansion, and quote removal after being expanded as described in +PROMPTING + + +above. This option is enabled by default. +
restricted_shell + +
+The shell sets this option if it is started in restricted mode (see +RESTRICTED SHELL + + +below). +The value may not be changed. +This is not reset when the startup files are executed, allowing +the startup files to discover whether or not a shell is restricted. +
shift_verbose + +
+If set, the +shift + +builtin prints an error message when the shift count exceeds the +number of positional parameters. +
sourcepath + +
+If set, the +source (.) builtin uses the value of +PATH + + +to find the directory containing the file supplied as an argument. +This option is enabled by default. +
xpg_echo + +
+If set, the echo builtin expands backslash-escape sequences +by default. +
+ +
suspend [-f]
+Suspend the execution of this shell until it receives a +SIGCONT + + +signal. The +-f + +option says not to complain if this is +a login shell; just suspend anyway. The return status is 0 unless +the shell is a login shell and +-f + +is not supplied, or if job control is not enabled. +
test expr
+ +
[ expr ]
+Return a status of 0 or 1 depending on +the evaluation of the conditional expression +expr. + +Each operator and operand must be a separate argument. +Expressions are composed of the primaries described above under +CONDITIONAL EXPRESSIONS. + + +test does not accept any options, nor does it accept and ignore +an argument of -- as signifying the end of options. +

+ + +Expressions may be combined using the following operators, listed +in decreasing order of precedence. +

+ +
+
! expr + +
+True if +expr + +is false. +
( expr ) + +
+Returns the value of expr. +This may be used to override the normal precedence of operators. +
expr1 -a expr2
+True if both +expr1 + +and +expr2 + +are true. +
expr1 -o expr2
+True if either +expr1 + +or +expr2 + +is true. + +
+

+ +test and [ evaluate conditional +expressions using a set of rules based on the number of arguments. +

+ + + +

+
0 arguments
+The expression is false. +
1 argument
+The expression is true if and only if the argument is not null. +
2 arguments
+If the first argument is !, the expression is true if and +only if the second argument is null. +If the first argument is one of the unary conditional operators listed above +under +CONDITIONAL EXPRESSIONS, + + +the expression is true if the unary test is true. +If the first argument is not a valid unary conditional operator, the expression +is false. +
3 arguments
+If the second argument is one of the binary conditional operators listed above +under +CONDITIONAL EXPRESSIONS, + + +the result of the expression is the result of the binary test using +the first and third arguments as operands. +If the first argument is !, the value is the negation of +the two-argument test using the second and third arguments. +If the first argument is exactly ( and the third argument is +exactly ), the result is the one-argument test of the second +argument. +Otherwise, the expression is false. +The -a and -o operators are considered binary operators +in this case. +
4 arguments
+If the first argument is !, the result is the negation of +the three-argument expression composed of the remaining arguments. +Otherwise, the expression is parsed and evaluated according to +precedence using the rules listed above. +
5 or more arguments
+The expression is parsed and evaluated according to precedence +using the rules listed above. +
+ + +
times + +
+Print the accumulated user and system times for the shell and +for processes run from the shell. The return status is 0. +
trap [-lp] [[arg] sigspec ...]
+The command +arg + +is to be read and executed when the shell receives +signal(s) +sigspec. + +If +arg + +is absent (and there is a single sigspec) or +-, + +each specified signal is +reset to its original disposition (the value it had +upon entrance to the shell). +If +arg + +is the null string the signal specified by each +sigspec + +is ignored by the shell and by the commands it invokes. +If +arg + +is not present and +-p + +has been supplied, then the trap commands associated with each +sigspec + +are displayed. +If no arguments are supplied or if only +-p + +is given, +trap + +prints the list of commands associated with each signal. +The +-l + +option causes the shell to print a list of signal names and +their corresponding numbers. +Each +sigspec + +is either +a signal name defined in <signal.h>, or a signal number. +Signal names are case insensitive and the SIG prefix is optional. +If a +sigspec + +is +EXIT + + +(0) the command +arg + +is executed on exit from the shell. +If a +sigspec + +is +DEBUG, + + +the command +arg + +is executed before every simple command, for command, +case command, select command, every arithmetic for +command, and before the first command executes in a shell function (see +SHELL GRAMMAR + + +above). +Refer to the description of the extdebug option to the +shopt builtin for details of its effect on the DEBUG trap. +If a +sigspec + +is +ERR, + + +the command +arg + +is executed whenever a simple command has a non-zero exit status, +subject to the following conditions. +The +ERR + + +trap is not executed if the failed +command is part of the command list immediately following a +while + +or +until + +keyword, +part of the test in an +if + +statement, part of a +&& + +or +|| + +list, or if the command's return value is +being inverted via +!. + +These are the same conditions obeyed by the errexit option. +If a +sigspec + +is +RETURN, + + +the command +arg + +is executed each time a shell function or a script executed with the +. or source builtins finishes executing. +Signals ignored upon entry to the shell cannot be trapped or reset. +Trapped signals are reset to their original values in a child +process when it is created. +The return status is false if any +sigspec + +is invalid; otherwise +trap + +returns true. +
type [-aftpP] name [name ...]
+With no options, +indicate how each +name + +would be interpreted if used as a command name. +If the +-t + +option is used, +type + +prints a string which is one of +alias, + +keyword, + +function, + +builtin, + +or +file + +if +name + +is an alias, shell reserved word, function, builtin, or disk file, +respectively. +If the +name + +is not found, then nothing is printed, and an exit status of false +is returned. +If the +-p + +option is used, +type + +either returns the name of the disk file +that would be executed if +name + +were specified as a command name, +or nothing if +type -t name + +would not return +file. + +The +-P + +option forces a +PATH + + +search for each name, even if +type -t name + +would not return +file. + +If a command is hashed, +-p + +and +-P + +print the hashed value, not necessarily the file that appears +first in +PATH. + + +If the +-a + +option is used, +type + +prints all of the places that contain +an executable named +name. + +This includes aliases and functions, +if and only if the +-p + +option is not also used. +The table of hashed commands is not consulted +when using +-a. + +The +-f + +option suppresses shell function lookup, as with the command builtin. +type + +returns true if any of the arguments are found, false if +none are found. +
ulimit [-SHacdefilmnpqrstuvx [limit]]
+Provides control over the resources available to the shell and to +processes started by it, on systems that allow such control. +The -H and -S options specify that the hard or soft limit is +set for the given resource. A hard limit cannot be increased once it +is set; a soft limit may be increased up to the value of the hard limit. +If neither -H nor -S is specified, both the soft and hard +limits are set. +The value of +limit + +can be a number in the unit specified for the resource +or one of the special values +hard, + +soft, + +or +unlimited, + +which stand for the current hard limit, the current soft limit, and +no limit, respectively. +If +limit + +is omitted, the current value of the soft limit of the resource is +printed, unless the -H option is given. When more than one +resource is specified, the limit name and unit are printed before the value. +Other options are interpreted as follows: +
+ +
+
-a + +
+All current limits are reported +
-c + +
+The maximum size of core files created +
-d + +
+The maximum size of a process's data segment +
-e + +
+The maximum scheduling priority ("nice") +
-f + +
+The maximum size of files created by the shell +
-i + +
+The maximum number of pending signals +
-l + +
+The maximum size that may be locked into memory +
-m + +
+The maximum resident set size +
-n + +
+The maximum number of open file descriptors (most systems do not +allow this value to be set) +
-p + +
+The pipe size in 512-byte blocks (this may not be set) +
-q + +
+The maximum number of bytes in POSIX message queues +
-r + +
+The maximum real-time scheduling priority +
-s + +
+The maximum stack size +
-t + +
+The maximum amount of cpu time in seconds +
-u + +
+The maximum number of processes available to a single user +
-v + +
+The maximum amount of virtual memory available to the shell +
-x + +
+The maximum number of file locks + +
+

+ +If +limit + +is given, it is the new value of the specified resource (the +-a + +option is display only). +If no option is given, then +-f + +is assumed. Values are in 1024-byte increments, except for +-t, + +which is in seconds, +-p, + +which is in units of 512-byte blocks, +and +-n + +and +-u, + +which are unscaled values. +The return status is 0 unless an invalid option or argument is supplied, +or an error occurs while setting a new limit. +

+ +
umask [-p] [-S] [mode]
+The user file-creation mask is set to +mode. + +If +mode + +begins with a digit, it +is interpreted as an octal number; otherwise +it is interpreted as a symbolic mode mask similar +to that accepted by +chmod(1). + +If +mode + +is omitted, the current value of the mask is printed. +The +-S + +option causes the mask to be printed in symbolic form; the +default output is an octal number. +If the +-p + +option is supplied, and +mode + +is omitted, the output is in a form that may be reused as input. +The return status is 0 if the mode was successfully changed or if +no mode argument was supplied, and false otherwise. +
unalias [-a] [name ...]
+Remove each name from the list of defined aliases. If +-a + +is supplied, all alias definitions are removed. The return +value is true unless a supplied +name + +is not a defined alias. +
unset [-fv] [name ...]
+For each +name, + +remove the corresponding variable or function. +If no options are supplied, or the +-v + +option is given, each +name + +refers to a shell variable. +Read-only variables may not be unset. +If +-f + +is specified, each +name + +refers to a shell function, and the function definition +is removed. +Each unset variable or function is removed from the environment +passed to subsequent commands. +If any of +RANDOM, + + +SECONDS, + + +LINENO, + + +HISTCMD, + + +FUNCNAME, + + +GROUPS, + + +or +DIRSTACK + + +are unset, they lose their special properties, even if they are +subsequently reset. The exit status is true unless a +name + +is readonly. +
wait [n ...]
+Wait for each specified process and return its termination status. +Each +n + +may be a process +ID or a job specification; if a job spec is given, all processes +in that job's pipeline are waited for. If +n + +is not given, all currently active child processes +are waited for, and the return status is zero. If +n + +specifies a non-existent process or job, the return status is +127. Otherwise, the return status is the exit status of the last +process or job waited for. + + +
+  +

RESTRICTED SHELL

+ + + +

+ +If +bash + +is started with the name +rbash, + +or the +-r + +option is supplied at invocation, +the shell becomes restricted. +A restricted shell is used to +set up an environment more controlled than the standard shell. +It behaves identically to +bash + +with the exception that the following are disallowed or not performed: +

+
*
+changing directories with cd +
*
+setting or unsetting the values of +SHELL, + +PATH, + +ENV, + +or +BASH_ENV + +
*
+specifying command names containing +/ + +
*
+specifying a file name containing a +/ + +as an argument to the +. + +builtin command +
*
+Specifying a filename containing a slash as an argument to the +-p + +option to the +hash + +builtin command +
*
+importing function definitions from the shell environment at startup +
*
+parsing the value of SHELLOPTS from the shell environment at startup +
*
+redirecting output using the >, >|, <>, >&, &>, and >> redirection operators +
*
+using the +exec + +builtin command to replace the shell with another command +
*
+adding or deleting builtin commands with the +-f + +and +-d + +options to the +enable + +builtin command +
*
+Using the enable builtin command to enable disabled shell builtins +
*
+specifying the +-p + +option to the +command + +builtin command +
*
+turning off restricted mode with +set +r or set +o restricted. +
+

+ +These restrictions are enforced after any startup files are read. +

+ + + When a command that is found to be a shell script is executed +(see +COMMAND EXECUTION + + + +above), + +rbash + +turns off any restrictions in the shell spawned to execute the +script. + + +  +

BUG REPORTS

+ +If you find a bug in +bash, + +you should report it. But first, you should +make sure that it really is a bug, and that it appears in the latest +version of +bash. + +The latest version is always available from +ftp://ftp.gnu.org/pub/bash/. +

+ +Once you have determined that a bug actually exists, use the +bashbug + +command to submit a bug report. +If you have a fix, you are encouraged to mail that as well! +Suggestions and `philosophical' bug reports may be mailed +to bug-bash@gnu.org or posted to the Usenet +newsgroup +gnu.bash.bug. + +

+ +ALL bug reports should include: +

+ + +

+
The version number of bash
+
The hardware and operating system
+
The compiler used to compile
+
A description of the bug behaviour
+
A short script or `recipe' which exercises the bug
+ +
+

+ +bashbug + +inserts the first three items automatically into the template +it provides for filing a bug report. +

+ +Comments and bug reports concerning +this manual page should be directed to +chet@po.cwru.edu. + +  +

BUGS

+ +

+ +It's too big and too slow. +

+ +There are some subtle differences between +bash + +and traditional versions of +sh, + +mostly because of the +POSIX + + +specification. +

+ +Aliases are confusing in some uses. +

+ +Shell builtin commands and functions are not stoppable/restartable. +

+ +Compound commands and command sequences of the form `a ; b ; c' +are not handled gracefully when process suspension is attempted. +When a process is stopped, the shell immediately executes the next +command in the sequence. +It suffices to place the sequence of commands between +parentheses to force it into a subshell, which may be stopped as +a unit. +

+ +Commands inside of $(...) command substitution are not +parsed until substitution is attempted. This will delay error +reporting until some time after the command is entered. For example, +unmatched parentheses, even inside shell comments, will result in +error messages while the construct is being read. +

+ +Array variables may not (yet) be exported. + + + +

4.3.1 The Set Builtin

- +
lithist +
If enabled, and the cmdhist +option is enabled, multi-line commands are saved to the history with +embedded newlines rather than using semicolon separators where possible.

-This builtin is so complicated that it deserves its own section. set -allows you to change the values of shell options and set the positional -parameters, or to display the names and values of shell variables. -

- -

-
set -
-
 
set [--abefhkmnptuvxBCEHPT] [-o option] [argument ...]
-set [+abefhkmnptuvxBCEHPT] [+o option] [argument ...]
-

- -If no options or arguments are supplied, set displays the names -and values of all shell variables and functions, sorted according to the -current locale, in a format that may be reused as input -for setting or resetting the currently-set variables. -Read-only variables cannot be reset. -In POSIX mode, only shell variables are listed. -

+

login_shell +
The shell sets this option if it is started as a login shell +(see section 6.1 Invoking Bash). +The value may not be changed. +

-When options are supplied, they set or unset shell attributes. -Options, if specified, have the following meanings: -

+

mailwarn +
If set, and a file that Bash is checking for mail has been +accessed since the last time it was checked, the message +"The mail in mailfile has been read" is displayed. +

-

-
-a -
Mark variables and function which are modified or created for export -to the environment of subsequent commands. +
no_empty_cmd_completion +
If set, and Readline is being used, Bash will not attempt to search +the PATH for possible completions when completion is attempted +on an empty line.

-

-b -
Cause the status of terminated background jobs to be reported -immediately, rather than before printing the next primary prompt. +
nocaseglob +
If set, Bash matches filenames in a case-insensitive fashion when +performing filename expansion.

-

-e -
Exit immediately if a simple command (see section 3.2.1 Simple Commands) exits -with a non-zero status, unless the command that fails is part of the -command list immediately following a while or until keyword, -part of the test in an if statement, -part of a && or || list, -any command in a pipeline but the last, -or if the command's return status is being inverted using !. -A trap on ERR, if set, is executed before the shell exits. +
nocasematch +
If set, Bash matches patterns in a case-insensitive fashion when +performing matching while executing case or [[ +conditional commands.

-

-f -
Disable file name generation (globbing). +
nullglob +
If set, Bash allows filename patterns which match no +files to expand to a null string, rather than themselves.

-

-h -
Locate and remember (hash) commands as they are looked up for execution. +
progcomp +
If set, the programmable completion facilities +(see section 8.6 Programmable Completion) are enabled. This option is enabled by default.

-

-k -
All arguments in the form of assignment statements are placed -in the environment for a command, not just those that precede -the command name. +
promptvars +
If set, prompt strings undergo +parameter expansion, command substitution, arithmetic +expansion, and quote removal after being expanded +as described below (see section 6.9 Controlling the Prompt). +This option is enabled by default.

-

-m -
Job control is enabled (see section 7. Job Control). +
restricted_shell +
The shell sets this option if it is started in restricted mode +(see section 6.10 The Restricted Shell). +The value may not be changed. +This is not reset when the startup files are executed, allowing +the startup files to discover whether or not a shell is restricted.

-

-n -
Read commands but do not execute them; this may be used to check a -script for syntax errors. -This option is ignored by interactive shells. +
shift_verbose +
If this is set, the shift +builtin prints an error message when the shift count exceeds the +number of positional parameters.

-

-o option-name -

- -Set the option corresponding to option-name: -

- -

-
allexport -
Same as -a. +
sourcepath +
If set, the source builtin uses the value of PATH +to find the directory containing the file supplied as an argument. +This option is enabled by default.

-

braceexpand -
Same as -B. +
xpg_echo +
If set, the echo builtin expands backslash-escape sequences +by default.

-

emacs -
Use an emacs-style line editing interface (see section 8. Command Line Editing). +

-

errexit -

+The return status when listing options is zero if all optnames +are enabled, non-zero otherwise. +When setting or unsetting options, the return status is zero unless an +optname is not a valid shell option. +

-

errtrace -
Same as -E. +
source +
+
 
source filename
+
A synonym for . (see section 4.1 Bourne Shell Builtins).

-

functrace -

type +
+
 
type [-afptP] [name ...]
+
For each name, indicate how it would be interpreted if used as a +command name.

-

hashall -
Same as -h. -

+If the `-t' option is used, type prints a single word +which is one of `alias', `function', `builtin', +`file' or `keyword', +if name is an alias, shell function, shell builtin, +disk file, or shell reserved word, respectively. +If the name is not found, then nothing is printed, and +type returns a failure status. +

-

histexpand -
Same as -H. -

+If the `-p' option is used, type either returns the name +of the disk file that would be executed, or nothing if `-t' +would not return `file'. +

-

history -
Enable command history, as described in 9.1 Bash History Facilities. -This option is on by default in interactive shells. -

+The `-P' option forces a path search for each name, even if +`-t' would not return `file'. +

-

ignoreeof -
An interactive shell will not exit upon reading EOF. -

+If a command is hashed, `-p' and `-P' print the hashed value, +not necessarily the file that appears first in $PATH. +

-

keyword -
Same as -k. -

+If the `-a' option is used, type returns all of the places +that contain an executable named file. +This includes aliases and functions, if and only if the `-p' option +is not also used. +

-

monitor -
Same as -m. +If the `-f' option is used, type does not attempt to find +shell functions, as with the command builtin. +

+ +The return status is zero if any of the names are found, non-zero +if none are found. +

+ +

typeset +
+
 
typeset [-afFrxi] [-p] [name[=value] ...]
+
The typeset command is supplied for compatibility with the Korn +shell; however, it has been deprecated in favor of the declare +builtin command.

-

noclobber -
Same as -C. +
ulimit +
+
 
ulimit [-acdefilmnpqrstuvxSH] [limit]
+
ulimit provides control over the resources available to processes +started by the shell, on systems that allow such control. If an +option is given, it is interpreted as follows: +

physical -
Same as -P. +
-i +
The maximum number of pending signals.

-

pipefail -
If set, the return value of a pipeline is the value of the last -(rightmost) command to exit with a non-zero status, or zero if all -commands in the pipeline exit successfully. -This option is disabled by default. +
-l +
The maximum size that may be locked into memory.

-

posix -
Change the behavior of Bash where the default operation differs -from the POSIX standard to match the standard -(see section 6.11 Bash POSIX Mode). -This is intended to make Bash behave as a strict superset of that -standard. +
-m +
The maximum resident set size.

-

privileged -
Same as -p. +
-n +
The maximum number of open file descriptors.

-

verbose -

The maximum number of bytes in POSIX message queues.

-

xtrace -
Same as -x. -
+
-r +
The maximum real-time scheduling priority.

-

-p -
Turn on privileged mode. -In this mode, the $BASH_ENV and $ENV files are not -processed, shell functions are not inherited from the environment, -and the SHELLOPTS variable, if it appears in the environment, -is ignored. -If the shell is started with the effective user (group) id not equal to the -real user (group) id, and the -p option is not supplied, these actions -are taken and the effective user id is set to the real user id. -If the -p option is supplied at startup, the effective user id is -not reset. -Turning this option off causes the effective user -and group ids to be set to the real user and group ids. +
-s +
The maximum stack size.

-t -
Exit after reading and executing one command. +
The maximum amount of cpu time in seconds.

-u -
Treat unset variables as an error when performing parameter expansion. -An error message will be written to the standard error, and a non-interactive -shell will exit. +

The maximum amount of virtual memory available to the process.

-x -
Print a trace of simple commands, for commands, case -commands, select commands, and arithmetic for commands -and their arguments or associated word lists after they are -expanded and before they are executed. The value of the PS4 -variable is expanded and the resultant value is printed before -the command and its expanded arguments. -

- -

-B -
The shell will perform brace expansion (see section 3.5.1 Brace Expansion). -This option is on by default. -

- -

-C -
Prevent output redirection using `>', `>&', and `<>' -from overwriting existing files. -

- -

-E -
If set, any trap on ERR is inherited by shell functions, command -substitutions, and commands executed in a subshell environment. -The ERR trap is normally not inherited in such cases. -

- -

-H -
Enable `!' style history substitution (see section 9.3 History Expansion). -This option is on by default for interactive shells. -

- -

-P -
If set, do not follow symbolic links when performing commands such as -cd which change the current directory. The physical directory -is used instead. By default, Bash follows -the logical chain of directories when performing commands -which change the current directory. -

- -For example, if `/usr/sys' is a symbolic link to `/usr/local/sys' -then: -
 
$ cd /usr/sys; echo $PWD
-/usr/sys
-$ cd ..; pwd
-/usr
-

- -If set -P is on, then: -
 
$ cd /usr/sys; echo $PWD
-/usr/local/sys
-$ cd ..; pwd
-/usr/local
-

- -

-T -
If set, any trap on DEBUG and RETURN are inherited by -shell functions, command substitutions, and commands executed -in a subshell environment. -The DEBUG and RETURN traps are normally not inherited -in such cases. -

- -

-- -
If no arguments follow this option, then the positional parameters are -unset. Otherwise, the positional parameters are set to the -arguments, even if some of them begin with a `-'. +
The maximum number of file locks.

-

- -
Signal the end of options, cause all remaining arguments -to be assigned to the positional parameters. The `-x' -and `-v' options are turned off. -If there are no arguments, the positional parameters remain unchanged.

-Using `+' rather than `-' causes these options to be -turned off. The options can also be used upon invocation of the -shell. The current set of options may be found in $-. +If limit is given, it is the new value of the specified resource; +the special limit values hard, soft, and +unlimited stand for the current hard limit, the current soft limit, +and no limit, respectively. +Otherwise, the current value of the soft limit for the specified resource +is printed, unless the `-H' option is supplied. +When setting new limits, if neither `-H' nor `-S' is supplied, +both the hard and soft limits are set. +If no option is given, then `-f' is assumed. Values are in 1024-byte +increments, except for `-t', which is in seconds, `-p', +which is in units of 512-byte blocks, and `-n' and `-u', which +are unscaled values.

-The remaining N arguments are positional parameters and are -assigned, in order, to $1, $2, ... $N. -The special parameter # is set to N. +The return status is zero unless an invalid option or argument is supplied, +or an error occurs while setting a new limit. +

+ +

unalias +
+
 
unalias [-a] [name ... ]
+

+ +Remove each name from the list of aliases. If `-a' is +supplied, all aliases are removed. +Aliases are described in 6.6 Aliases.

-The return status is always zero unless an invalid option is supplied.

4.3.2 The Shopt Builtin

- +

4.3 The Set Builtin

+

-This builtin allows you to change additional shell optional behavior. +This builtin is so complicated that it deserves its own section.

- -
shopt +
set
-
 
shopt [-pqsu] [-o] [optname ...]
-
Toggle the values of variables controlling optional shell behavior. -With no options, or with the `-p' option, a list of all settable -options is displayed, with an indication of whether or not each is set. -The `-p' option causes output to be displayed in a form that -may be reused as input. -Other options have the following meanings: -

+
 
set [--abefhkmnptuvxBCHP] [-o option] [argument ...]
+

+ +If no options or arguments are supplied, set displays the names +and values of all shell variables and functions, sorted according to the +current locale, in a format that may be reused as input +for setting or resetting the currently-set variables. +Read-only variables cannot be reset. +In POSIX mode, only shell variables are listed. +

+ +When options are supplied, they set or unset shell attributes. +Options, if specified, have the following meanings: +

-
-s -
Enable (set) each optname. +
-a +
Mark variables and function which are modified or created for export +to the environment of subsequent commands.

-

-u -
Disable (unset) each optname. +
-b +
Cause the status of terminated background jobs to be reported +immediately, rather than before printing the next primary prompt. +

+ +

-e +
Exit immediately if a simple command (see section 3.2.1 Simple Commands) exits +with a non-zero status, unless the command that fails is part of the +command list immediately following a while or until +keyword, part of the test in an if statement, +part of a && or || list, or if the command's return +status is being inverted using !. +A trap on ERR, if set, is executed before the shell exits. +

+ +

-f +
Disable file name generation (globbing). +

+ +

-h +
Locate and remember (hash) commands as they are looked up for execution. +This option is enabled by default.

-

-q -
Suppresses normal output; the return status -indicates whether the optname is set or unset. -If multiple optname arguments are given with `-q', -the return status is zero if all optnames are enabled; -non-zero otherwise. +
-k +
All arguments in the form of assignment statements are placed +in the environment for a command, not just those that precede +the command name.

-

-o -
Restricts the values of -optname to be those defined for the `-o' option to the -set builtin (see section 4.3.1 The Set Builtin). -
+
-m +
Job control is enabled (see section 7. Job Control).

-If either `-s' or `-u' -is used with no optname arguments, the display is limited to -those options which are set or unset, respectively. -

+

-n +
Read commands but do not execute them; this may be used to check a +script for syntax errors. +This option is ignored by interactive shells. +

-Unless otherwise noted, the shopt options are disabled (off) -by default. -

+

-o option-name +

-The return status when listing options is zero if all optnames -are enabled, non-zero otherwise. When setting or unsetting options, -the return status is zero unless an optname is not a valid shell -option. +Set the option corresponding to option-name:

-The list of shopt options is:

- -
autocd -
If set, a command name that is the name of a directory is executed as if -it were the argument to the cd command. -This option is only used by interactive shells. -

- -

cdable_vars -
If this is set, an argument to the cd builtin command that -is not a directory is assumed to be the name of a variable whose -value is the directory to change to. -

- -

cdspell -
If set, minor errors in the spelling of a directory component in a -cd command will be corrected. -The errors checked for are transposed characters, -a missing character, and a character too many. -If a correction is found, the corrected path is printed, -and the command proceeds. -This option is only used by interactive shells. +
allexport +
Same as -a.

-

checkhash -
If this is set, Bash checks that a command found in the hash -table exists before trying to execute it. If a hashed command no -longer exists, a normal path search is performed. +
braceexpand +
Same as -B.

-

checkjobs -
If set, Bash lists the status of any stopped and running jobs before -exiting an interactive shell. If any jobs are running, this causes -the exit to be deferred until a second exit is attempted without an -intervening command (see section 7. Job Control). -The shell always postpones exiting if any jobs are stopped. +
emacs +
Use an emacs-style line editing interface (see section 8. Command Line Editing).

-

checkwinsize -
If set, Bash checks the window size after each command -and, if necessary, updates the values of -LINES and COLUMNS. +
errexit +
Same as -e.

-

cmdhist -
If set, Bash -attempts to save all lines of a multiple-line -command in the same history entry. This allows -easy re-editing of multi-line commands. +
errtrace +
Same as -E.

-

dotglob -
If set, Bash includes filenames beginning with a `.' in -the results of filename expansion. +
functrace +
Same as -T.

-

execfail -
If this is set, a non-interactive shell will not exit if -it cannot execute the file specified as an argument to the exec -builtin command. An interactive shell does not exit if exec -fails. +
hashall +
Same as -h.

-

expand_aliases -
If set, aliases are expanded as described below under Aliases, -6.6 Aliases. -This option is enabled by default for interactive shells. +
histexpand +
Same as -H.

-

extdebug -
If set, behavior intended for use by debuggers is enabled: +
history +
Enable command history, as described in 9.1 Bash History Facilities. +This option is on by default in interactive shells.

-

    -
  1. -The `-F' option to the declare builtin (see section 4.2 Bash Builtin Commands) -displays the source file name and line number corresponding to each function -name supplied as an argument. +
    ignoreeof +
    An interactive shell will not exit upon reading EOF.

    -

  2. -If the command run by the DEBUG trap returns a non-zero value, the -next command is skipped and not executed. +
    keyword +
    Same as -k.

    -

  3. -If the command run by the DEBUG trap returns a value of 2, and the -shell is executing in a subroutine (a shell function or a shell script -executed by the . or source builtins), a call to -return is simulated. +
    monitor +
    Same as -m.

    -

  4. -BASH_ARGC and BASH_ARGV are updated as described in their -descriptions (see section 5.2 Bash Variables). +
    noclobber +
    Same as -C.

+          *Note Bash Variables::, for a description of `FIGNORE'.  This
+          option is enabled by default.
+
+    `gnu_errfmt'
+          If set, shell error messages are written in the standard GNU
+          error message format.
+
+    `histappend'
+          If set, the history list is appended to the file named by the
+          value of the `HISTFILE' variable when the shell exits, rather
+          than overwriting the file.
+
+    `histreedit'
+          If set, and Readline is being used, a user is given the
+          opportunity to re-edit a failed history substitution.
+
+    `histverify'
+          If set, and Readline is being used, the results of history
+          substitution are not immediately passed to the shell parser.
+          Instead, the resulting line is loaded into the Readline
+          editing buffer, allowing further modification.
+
+    `hostcomplete'
+          If set, and Readline is being used, Bash will attempt to
+          perform hostname completion when a word containing a `@' is
+          being completed (*note Commands For Completion::).  This
+          option is enabled by default.
+
+    `huponexit'
+          If set, Bash will send `SIGHUP' to all jobs when an
+          interactive login shell exits (*note Signals::).
+
+    `interactive_comments'
+          Allow a word beginning with `#' to cause that word and all
+          remaining characters on that line to be ignored in an
+          interactive shell.  This option is enabled by default.
+
+    `lithist'
+          If enabled, and the `cmdhist' option is enabled, multi-line
+          commands are saved to the history with embedded newlines
+          rather than using semicolon separators where possible.
+
+    `login_shell'
+          The shell sets this option if it is started as a login shell
+          (*note Invoking Bash::).  The value may not be changed.
+
+    `mailwarn'
+          If set, and a file that Bash is checking for mail has been
+          accessed since the last time it was checked, the message
+          `"The mail in MAILFILE has been read"' is displayed.
+
+    `no_empty_cmd_completion'
+          If set, and Readline is being used, Bash will not attempt to
+          search the `PATH' for possible completions when completion is
+          attempted on an empty line.
+
+    `nocaseglob'
+          If set, Bash matches filenames in a case-insensitive fashion
+          when performing filename expansion.
+
+    `nocasematch'
+          If set, Bash matches patterns in a case-insensitive fashion
+          when performing matching while executing `case' or `[['
+          conditional commands.
+
+    `nullglob'
+          If set, Bash allows filename patterns which match no files to
+          expand to a null string, rather than themselves.
+
+    `progcomp'
+          If set, the programmable completion facilities (*note
+          Programmable Completion::) are enabled.  This option is
+          enabled by default.
+
+    `promptvars'
+          If set, prompt strings undergo parameter expansion, command
+          substitution, arithmetic expansion, and quote removal after
+          being expanded as described below (*note Printing a Prompt::).
+          This option is enabled by default.
+
+    `restricted_shell'
+          The shell sets this option if it is started in restricted mode
+          (*note The Restricted Shell::).  The value may not be changed.
+          This is not reset when the startup files are executed,
+          allowing the startup files to discover whether or not a shell
+          is restricted.
+
+    `shift_verbose'
+          If this is set, the `shift' builtin prints an error message
+          when the shift count exceeds the number of positional
+          parameters.
+
+    `sourcepath'
+          If set, the `source' builtin uses the value of `PATH' to find
+          the directory containing the file supplied as an argument.
+          This option is enabled by default.
+
+    `xpg_echo'
+          If set, the `echo' builtin expands backslash-escape sequences
+          by default.
+
+
+     The return status when listing options is zero if all OPTNAMES are
+     enabled, non-zero otherwise.  When setting or unsetting options,
+     the return status is zero unless an OPTNAME is not a valid shell
+     option.

-          the logical chain of directories when performing commands
-          which change the current directory.
-
-          For example, if `/usr/sys' is a symbolic link to
-          `/usr/local/sys' then:

-          are normally not inherited in such cases.
-
-    `--'
-          If no arguments follow this option, then the positional

-          options are turned off.  If there are no arguments, the
-          positional parameters remain unchanged.
-
-     Using `+' rather than `-' causes these options to be turned off.
-     The options can also be used upon invocation of the shell.  The
-     current set of options may be found in `$-'.
-
-     The remaining N ARGUMENTS are positional parameters and are
-     assigned, in order, to `$1', `$2', ...  `$N'.  The special
-     parameter `#' is set to N.
-
-     The return status is always zero unless an invalid option is

-4.3.2 The Shopt Builtin
------------------------
-
-This builtin allows you to change additional shell optional behavior.
-
-`shopt'
-          shopt [-pqsu] [-o] [OPTNAME ...]
-     Toggle the values of variables controlling optional shell behavior.
-     With no options, or with the `-p' option, a list of all settable
-     options is displayed, with an indication of whether or not each is
-     set.  The `-p' option causes output to be displayed in a form that
-     may be reused as input.  Other options have the following meanings:
-
-    `-s'
-          Enable (set) each OPTNAME.
-
-    `-u'
-          Disable (unset) each OPTNAME.
-
-    `-q'
-          Suppresses normal output; the return status indicates whether
-          the OPTNAME is set or unset.  If multiple OPTNAME arguments
-          are given with `-q', the return status is zero if all
-          OPTNAMES are enabled; non-zero otherwise.
-
-    `-o'
-          Restricts the values of OPTNAME to be those defined for the
-          `-o' option to the `set' builtin (*note The Set Builtin::).
-
-     If either `-s' or `-u' is used with no OPTNAME arguments, the
-     display is limited to those options which are set or unset,
-     respectively.
-
-     Unless otherwise noted, the `shopt' options are disabled (off) by
-     default.
-
-     The return status when listing options is zero if all OPTNAMES are
-     enabled, non-zero otherwise.  When setting or unsetting options,
-     the return status is zero unless an OPTNAME is not a valid shell
-     option.
-
-     The list of `shopt' options is:
-    `autocd'
-          If set, a command name that is the name of a directory is
-          executed as if it were the argument to the `cd' command.
-          This option is only used by interactive shells.
-
-    `cdable_vars'
-          If this is set, an argument to the `cd' builtin command that
-          is not a directory is assumed to be the name of a variable
-          whose value is the directory to change to.
-
-    `cdspell'
-          If set, minor errors in the spelling of a directory component
-          in a `cd' command will be corrected.  The errors checked for
-          are transposed characters, a missing character, and a
-          character too many.  If a correction is found, the corrected
-          path is printed, and the command proceeds.  This option is
-          only used by interactive shells.
-
-    `checkhash'
-          If this is set, Bash checks that a command found in the hash
-          table exists before trying to execute it.  If a hashed
-          command no longer exists, a normal path search is performed.
-
-    `checkjobs'
-          If set, Bash lists the status of any stopped and running jobs
-          before exiting an interactive shell.  If any jobs are
-          running, this causes the exit to be deferred until a second
-          exit is attempted without an intervening command (*note Job
-          Control::).  The shell always postpones exiting if any jobs
-          are stopped.
-
-    `checkwinsize'
-          If set, Bash checks the window size after each command and,
-          if necessary, updates the values of `LINES' and `COLUMNS'.
-
-    `cmdhist'
-          If set, Bash attempts to save all lines of a multiple-line
-          command in the same history entry.  This allows easy
-          re-editing of multi-line commands.
-
-    `dotglob'
-          If set, Bash includes filenames beginning with a `.' in the
-          results of filename expansion.
-
-    `execfail'
-          If this is set, a non-interactive shell will not exit if it
-          cannot execute the file specified as an argument to the `exec'
-          builtin command.  An interactive shell does not exit if `exec'
-          fails.
-
-    `expand_aliases'
-          If set, aliases are expanded as described below under Aliases,
-          *Note Aliases::.  This option is enabled by default for
-          interactive shells.
-
-    `extdebug'
-          If set, behavior intended for use by debuggers is enabled:
-
-            1. The `-F' option to the `declare' builtin (*note Bash
-               Builtins::) displays the source file name and line
-               number corresponding to each function name supplied as
-               an argument.
-
-            2. If the command run by the `DEBUG' trap returns a
-               non-zero value, the next command is skipped and not
-               executed.
-
-            3. If the command run by the `DEBUG' trap returns a value
-               of 2, and the shell is executing in a subroutine (a
-               shell function or a shell script executed by the `.' or
-               `source' builtins), a call to `return' is simulated.
-
-            4. `BASH_ARGC' and `BASH_ARGV' are updated as described in
-               their descriptions (*note Bash Variables::).
+         `noglob'
+               Same as `-f'.
 
-            5. Function tracing is enabled:  command substitution,
-               shell functions, and subshells invoked with `( COMMAND
-               )' inherit the `DEBUG' and `RETURN' traps.
+         `nolog'
+               Currently ignored.
 
-            6. Error tracing is enabled:  command substitution, shell
-               functions, and subshells invoked with `( COMMAND )'
-               inherit the `ERROR' trap.
+         `notify'
+               Same as `-b'.
 
-    `extglob'
-          If set, the extended pattern matching features described above
-          (*note Pattern Matching::) are enabled.
+         `nounset'
+               Same as `-u'.
 
-    `extquote'
-          If set, `$'STRING'' and `$"STRING"' quoting is performed
-          within `${PARAMETER}' expansions enclosed in double quotes.
-          This option is enabled by default.
+         `onecmd'
+               Same as `-t'.
 
-    `failglob'
-          If set, patterns which fail to match filenames during
-          pathname expansion result in an expansion error.
+         `physical'
+               Same as `-P'.
 
-    `force_fignore'
-          If set, the suffixes specified by the `FIGNORE' shell variable
-          cause words to be ignored when performing word completion
-          even if the ignored words are the only possible completions.
-          *Note Bash Variables::, for a description of `FIGNORE'.  This
-          option is enabled by default.
+         `pipefail'
+               If set, the return value of a pipeline is the value of
+               the last (rightmost) command to exit with a non-zero
+               status, or zero if all commands in the pipeline exit
+               successfully.  This option is disabled by default.
 
-    `gnu_errfmt'
-          If set, shell error messages are written in the standard GNU
-          error message format.
+         `posix'

+          variable is expanded and the resultant value is printed before
+          the command and its expanded arguments.
 
-    `no_empty_cmd_completion'
-          If set, and Readline is being used, Bash will not attempt to
-          search the `PATH' for possible completions when completion is
-          attempted on an empty line.
+    `-B'
+          The shell will perform brace expansion (*note Brace
+          Expansion::).  This option is on by default.
 
-    `nocaseglob'
-          If set, Bash matches filenames in a case-insensitive fashion
-          when performing filename expansion.
+    `-C'
+          Prevent output redirection using `>', `>&', and `<>' from
+          overwriting existing files.
 
-    `nocasematch'
-          If set, Bash matches patterns in a case-insensitive fashion
-          when performing matching while executing `case' or `[['
-          conditional commands.
+    `-E'
+          If set, any trap on `ERR' is inherited by shell functions,
+          command substitutions, and commands executed in a subshell
+          environment.  The `ERR' trap is normally not inherited in
+          such cases.
 
-    `nullglob'
-          If set, Bash allows filename patterns which match no files to
-          expand to a null string, rather than themselves.
+    `-H'
+          Enable `!' style history substitution (*note History
+          Interaction::).  This option is on by default for interactive
+          shells.
 
-    `progcomp'
-          If set, the programmable completion facilities (*note
-          Programmable Completion::) are enabled.  This option is
-          enabled by default.
+    `-P'
+          If set, do not follow symbolic links when performing commands
+          such as `cd' which change the current directory.  The
+          physical directory is used instead.  By default, Bash follows
+          the logical chain of directories when performing commands
+          which change the current directory.
 
-    `promptvars'
-          If set, prompt strings undergo parameter expansion, command
-          substitution, arithmetic expansion, and quote removal after
-          being expanded as described below (*note Printing a Prompt::).
-          This option is enabled by default.
+          For example, if `/usr/sys' is a symbolic link to

-    `restricted_shell'
-          The shell sets this option if it is started in restricted mode
-          (*note The Restricted Shell::).  The value may not be changed.
-          This is not reset when the startup files are executed,
-          allowing the startup files to discover whether or not a shell
-          is restricted.
+          If `set -P' is on, then:

-          If this is set, the `shift' builtin prints an error message
-          when the shift count exceeds the number of positional
-          parameters.
+    `-T'
+          If set, any trap on `DEBUG' and `RETURN' are inherited by
+          shell functions, command substitutions, and commands executed
+          in a subshell environment.  The `DEBUG' and `RETURN' traps
+          are normally not inherited in such cases.
 
-    `sourcepath'
-          If set, the `source' builtin uses the value of `PATH' to find
-          the directory containing the file supplied as an argument.
-          This option is enabled by default.
+    `--'

-
-@item checkjobs
-If set, Bash lists the status of any stopped and running jobs before

+the command and its expanded arguments.
 
-@item nocaseglob
-If set, Bash matches filenames in a case-insensitive fashion when
-performing filename expansion.
+@item -B
+The shell will perform brace expansion (@pxref{Brace Expansion}).

-expansion, and quote removal after being expanded
-as described below (@pxref{Printing a Prompt}).
-This option is enabled by default.
+@item -P
+If set, do not follow symbolic links when performing commands such as
+@code{cd} which change the current directory.  The physical directory
+is used instead.  By default, Bash follows
+the logical chain of directories when performing commands
+which change the current directory.
 
-@item restricted_shell
-The shell sets this option if it is started in restricted mode
-(@pxref{The Restricted Shell}).
-The value may not be changed.
-This is not reset when the startup files are executed, allowing
-the startup files to discover whether or not a shell is restricted.

-@item sourcepath
-If set, the @code{source} builtin uses the value of @env{PATH}
-to find the directory containing the file supplied as an argument.
-This option is enabled by default.
+@item -T
+If set, any trap on @code{DEBUG} and @code{RETURN} are inherited by

+in a subshell environment.
+The @code{DEBUG} and @code{RETURN} traps are normally not inherited

        uummaasskk [--pp] [--SS] [_m_o_d_e]
               The user file-creation mask is set to _m_o_d_e.  If _m_o_d_e begins with
-              a digit, it is interpreted as an octal number; otherwise  it  is
-              interpreted  as a symbolic mode mask similar to that accepted by
-              _c_h_m_o_d(1).  If _m_o_d_e is omitted, the current value of the mask  is
-              printed.   The  --SS  option causes the mask to be printed in sym-
-              bolic form; the default output is an octal number.   If  the  --pp
+              a  digit,  it is interpreted as an octal number; otherwise it is
+              interpreted as a symbolic mode mask similar to that accepted  by

+              bolic  form;  the  default output is an octal number.  If the --pp
               option is supplied, and _m_o_d_e is omitted, the output is in a form
               that may be reused as input.  The return status is 0 if the mode

-
-Filename completion (and word completion in general) may appear to behave

-
-The colon is special to readline's word completion code:  it is one of the
-characters that breaks words for the completer.  Readline uses these characters
-in sort of the same way that bash uses $IFS: they break or separate the words
-the completion code hands to the application-specific or default word
-completion functions.  The original intent was to make it easy to edit
-colon-separated lists (such as $PATH in bash) in various applications using
-readline for input.
-
-This is complicated by the fact that some versions of the popular
-`bash-completion' programmable completion package have problems with the
-default completion behavior in the presence of colons.  
-
-The current set of completion word break characters is available in bash as
-the value of the COMP_WORDBREAKS variable.  Removing `:' from that value is
-enough to make the colon not special to completion:
-
-COMP_WORDBREAKS=${COMP_WORDBREAKS//:}

-You can also quote the colon with a backslash to achieve the same result

-E13) Why does filename completion misbehave if a colon appears in the filename?
-
-Filename completion (and word completion in general) may appear to behave
-improperly if there is a colon in the word to be completed.
-
-The colon is special to readline's word completion code:  it is one of the
-characters that breaks words for the completer.  Readline uses these characters
-in sort of the same way that bash uses $IFS: they break or separate the words
-the completion code hands to the application-specific or default word
-completion functions.  The original intent was to make it easy to edit
-colon-separated lists (such as $PATH in bash) in various applications using
-readline for input.
-
-This is complicated by the fact that some versions of the popular
-`bash-completion' programmable completion package have problems with the
-default completion behavior in the presence of colons.  
-
-The current set of completion word break characters is available in bash as
-the value of the COMP_WORDBREAKS variable.  Removing `:' from that value is
-enough to make the colon not special to completion:
-
-COMP_WORDBREAKS=${COMP_WORDBREAKS//:}
-
-You can also quote the colon with a backslash to achieve the same result
-temporarily.

-E13) Why does filename completion misbehave if a colon appears in the filename?
-
-Filename completion (and word completion in general) may appear to behave
-improperly if there is a colon in the word to be completed.
-
-The colon is special to readline's word completion code:  it is one of the
-characters that breaks words for the completer.  Readline uses these characters
-in sort of the same way that bash uses $IFS: they break or separate the words
-the completion code hands to the application-specific or default word
-completion functions.  The original intent was to make it easy to edit
-colon-separated lists (such as $PATH in bash) in various applications using
-readline for input.
-
-This is complicated by the fact that some versions of the popular
-`bash-completion' programmable completion package have problems with the
-default completion behavior in the presence of colons.  
-
-The current set of completion word break characters is available in bash as
-the value of the COMP_WORDBREAKS variable.  Removing `:' from that value is
-enough to make the colon not special to completion:
-
-COMP_WORDBREAKS=${COMP_WORDBREAKS//:}

-You can also quote the colon with a backslash to achieve the same result
