--- /dev/null
+This document details the changes between this version, bash-4.2-alpha,
+and the previous version, bash-4.1-release.
+
+1. Changes to Bash
+
+a. Fixed a bug in the parser when processing alias expansions containing
+ quoted newlines.
+
+b. Fixed a memory leak in associative array expansion.
+
+c. Fixed a bug that caused quoted here-strings to be requoted when printed.
+
+d. Fixed a bug in arithmetic expansion that caused the index in an array
+ expansion to be evaluated twice under certain circumstances.
+
+e. Fixed several bugs with the expansion and display of variables that have
+ been given attributes but not values and are technically unset.
+
+f. Fixed a bug that caused core dumps when using filename completion that
+ expands to a filename containing a globbing character.
+
+g. Fixed a bug that caused assignment statements preceding a special builtin
+ when running in Posix mode to not persist after the builtin completed
+ when the special builtin was executed in a shell function without any
+ local variables.
+
+h. Fixed a bug that caused a command to remain in the hash table even after
+ `hash command' did not find anything if there was already an existing
+ hashed pathname.
+
+i. Fixed several bugs caused by executing unsafe functions from a signal
+ handler in the cases where a signal handler is executed immediately
+ rather than setting a flag for later execution.
+
+j. Fixed a bug that caused some internal flag variables to be set
+ incorrectly if `read -t' timed out.
+
+k. Fixed a Posix compatibility issue by making sure that a backslash escaping
+ a `}' within a double-quoted ${...} parameter expansion is removed as part
+ of the parameter expansion.
+
+l. Fixed a bug that caused execution of a trap to overwrite PIPESTATUS.
+
+m. Fixed a bug that caused here documents to not be displayed correctly
+ when attached to commands inside compound commands.
+
+n. Fixed a bug that caused the printf builtin to use the wrong precision
+ when using the `*' modifier.
+
+o. Fixed a bug that caused an arriving SIGCHLD to interrupt output functions
+ like those invoked by echo or printf.
+
+p. Changed to use a more robust mechanism than eaccess(2) when test is
+ checking filenames for execution permission.
+
+q. Fixed a bug that caused spurious semicolons to be added into the command
+ history in certain cases.
+
+r. Fixed a bug that caused the shell to free non-allocated memory when
+ unsetting element 0 of an associative array after it was assigned
+ implicitly.
+
+s. Fixed a bug that could cause the shell to dump core if using the `v'
+ vi editing command on a multi-line command.
+
+t. Fixed a bug that left FIFOs opened by process substitutions open long
+ enough to potentially cause file descriptor exhaustion when running a
+ shell function or shell builtin.
+
+u. Fixed a bug that caused the history expansion functions to not recognize
+ process substitution or extended glob patterns as single words.
+
+v. Fixed a bug that caused restricted shells to set a restricted command's
+ exit status incorrectly.
+
+w. Fixed a bug that caused bash to ignore the wrong set of filenames when
+ completing a command using the `complete-filename' readline command.
+
+x. Fixed a bug that caused a -PID argument following a -s sig or -n sig to
+ not be interpreted as a signal specification.
+
+y. Changed posix-mode behavior of a parse error in a `.' script or `eval'
+ command to exit the shell under Posix-specified conditions. Previous
+ versions printed a warning.
+
+z. Fixed a bug in \W prompt expansion that resulted in incorrect expansion
+ in the event of overlapping strings.
+
+aa. Fixed a bug that caused the := parameter expansion operator to return the
+ wrong value as the result of the expansion.
+
+bb. When in Posix mode, a single quote is not treated specially in a
+ double-quoted ${...} expansion, unless the expansion operator is
+ # or % or the non-Posix `//', `^', and `,'. In particular, it does
+ not define a new quoting context. This is from Posix interpretation 221.
+
+cc. Fixed a bug that inadvertently allowed program names containing slashes
+ to be entered into the command hash table.
+
+dd. Fixed a bug that caused the select builtin to incorrectly compute the
+ display width of the arguments in the presence of multibyte characters.
+
+ee. Fixed a bug that caused bash to not change the xtrace file descriptor if
+ BASH_XTRACEFD was found in the shell environment at startup.
+
+ff. Fixed a memory leak in the pattern removal parameter expansion.
+
+gg. Fixed a bug that caused SIGINT to fail to interrupt a nested loop if the
+ loop was in a pipeline.
+
+hh. Fixed a problem in $(...) parsing that caused the parser to add an extra
+ space to a here-document delimiter if the first word contained a `/'.
+
+ii. Fixed a bug that caused functions defined with the `function' reserved
+ word to require braces around the function body.
+
+jj. Fixed a bug that caused bash to dump core when a variable expansion being
+ used as an array subscript failed.
+
+kk. Fixed a bug that caused bash to dump core if the case-modification
+ expansions were used on a variable with a null value.
+
+ll. Fixed a bug that caused partially-quoted strings to be split incorrectly
+ if a variable with a null value was expanded within double quotes.
+
+mm. The pattern substitution word expansion has been sped up dramatically
+ when running in a locale with multibyte characters.
+
+nn. Fixed a bug that caused history -a to not write the correct lines to
+ the history file if all the new lines in the history list were added
+ since the last time the history file was read or written.
+
+oo. Fixed a bug that caused completion of a word with an unclosed `` command
+ substitution to set the prompt incorrectly.
+
+pp. Fixed a bug that caused extended globbing patterns in $HISTIGNORE or
+ $GLOBIGNORE to be incorrectly scanned.
+
+qq. Fixed a bug caused by closing file descriptors 3-20 on shell startup. The
+ shell now sets them to close-on-exec.
+
+rr. Fixed a bug that caused the exit status of `exec file' to be set incorrectly
+ if `file' was a directory.
+
+ss. Fixed a bug in the `.' builtin to make a non-interactive posix-mode shell
+ exit if the file argument to `.' is not found. Prefixing exec with
+ `command' makes the shell not exit. Posix requires this behavior.
+
+tt. Fixed a bug that caused `sh -c 'command exec; exit 1' to hang.
+
+uu. Fixed a bug in $(...) command substitution parsing that caused the shell
+ to treat backslash-newline incorrectly when parsing a comment.
+
+vv. Fixed bug that caused brace expansion sequence generation to misbehave
+ when supplied integers greater than 2**31 - 1.
+
+ww. Fixed a bug that caused failure to save file descriptors for redirections
+ to corrupt shell file descriptors.
+
+xx. Fixed a bug that caused bash-forward-shellword to not correctly handle
+ quoted strings.
+
+2. Changes to Readline
+
+a. Fixed a bug that caused the unconverted filename to be added to the list of
+ completions when the application specified filename conversion functions.
+
+b. Fixed a bug that caused the wrong filename to be passed to opendir when the
+ application has specified a filename dequoting function.
+
+c. Fixed a bug when repeating a character search in vi mode in the case where
+ there was no search to repeat.
+
+d. When show-all-if-ambiguous is set, the completion routines no longer insert
+ a common match prefix that is shorter than the text being completed.
+
+e. The full set of vi editing commands may now be used in callback mode.
+
+f. Fixed a bug that caused readline to not update its idea of the terminal
+ dimensions while running in `no-echo' mode.
+
+h. Fixed a bug that caused readline to dump core if an application called
+ rl_prep_terminal without setting rl_instream.
+
+i. Fixed a bug that caused meta-prefixed characters bound to incremental
+ search forward or backward to not be recognized if they were typed
+ subsequently.
+
+j. The incremental search code treats key sequences that map to the same
+ functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
+
+k. Fixed a bug in menu-complete that caused it to misbehave with large
+ negative argument.
+
+l. Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
+ at the end of the line.
+
+3. New Features in Bash
+
+a. `exec -a foo' now sets $0 to `foo' in an executable shell script without a
+ leading #!.
+
+b. Subshells begun to execute command substitutions or run shell functions or
+ builtins in subshells do not reset trap strings until a new trap is
+ specified. This allows $(trap) to display the caller's traps and the
+ trap strings to persist until a new trap is set.
+
+c. `trap -p' will now show signals ignored at shell startup, though their
+ disposition still cannot be modified.
+
+d. $'...', echo, and printf understand \uXXXX and \UXXXXXXXX escape sequences.
+
+e. declare/typeset has a new `-g' option, which creates variables in the
+ global scope even when run in a shell function.
+
+f. test/[/[[ have a new -v variable unary operator, which returns success if
+ `variable' has been set.
+
+g. Posix parsing changes to allow `! time command' and multiple consecutive
+ instances of `!' (which toggle) and `time' (which have no cumulative
+ effect).
+
+h. Posix change to allow `time' as a command by itself to print the elapsed
+ user, system, and real times for the shell and its children.
+
+j. $((...)) is always parsed as an arithmetic expansion first, instead of as
+ a potential nested command substitution, as Posix requires.
+
+k. A new FUNCNEST variable to allow the user to control the maximum shell
+ function nesting (recursive execution) level.
+
+l. The mapfile builtin now supplies a third argument to the callback command:
+ the line about to be assigned to the supplied array index.
+
+m. The printf builtin has a new %(fmt)T specifier, which allows time values
+ to use strftime-like formatting.
+
+n. There is a new `compat41' shell option.
+
+o. The cd builtin has a new Posix-mandated `-e' option.
+
+p. Negative subscripts to indexed arrays, previously errors, now are treated
+ as offsets from the maximum assigned index + 1.
+
+q. Negative length specifications in the ${var:offset:length} expansion,
+ previously errors, are now treated as offsets from the end of the variable.
+
+r. Parsing change to allow `time -p --'.
+
+s. Posix-mode parsing change to not recognize `time' as a keyword if the
+ following token begins with a `-'. This means no more Posix-mode
+ `time -p'. Posix interpretation 267.
+
+t. There is a new `lastpipe' shell option that runs the last command of a
+ pipeline in the current shell context. The lastpipe option has no
+ effect if job control is enabled.
+
+u. History expansion no longer expands the `$!' variable expansion.
+
+v. Posix mode shells no longer exit if a variable assignment error occurs
+ with an assignment preceding a command that is not a special builtin.
+
+w. Non-interactive mode shells exit if -u is enabled an an attempt is made
+ to use an unset variable with the % or # expansions, the `//', `^', or
+ `,' expansions, or the parameter length expansion.
+
+x. Posix-mode shells use the argument passed to `.' as-is if a $PATH search
+ fails, effectively searching the current directory. Posix-2008 change.
+
+4. New Features in Readline
+
+a. The history library does not try to write the history filename in the
+ current directory if $HOME is unset. This closes a potential security
+ problem if the application does not specify a history filename.
+
+b. New bindable variable `completion-display-width' to set the number of
+ columns used when displaying completions.
+
+c. New bindable variable `completion-case-map' to cause case-insensitive
+ completion to treat `-' and `_' as identical.
+
+d. There are new bindable vi-mode command names to avoid readline's case-
+ insensitive matching not allowing them to be bound separately.
+
+e. New bindable variable `menu-complete-display-prefix' causes the menu
+ completion code to display the common prefix of the possible completions
+ before cycling through the list, instead of after.

+h. Fixed a bug that caused readline to dump core if an application called
+ rl_prep_terminal without setting rl_instream.
+
+i. Fixed a bug that caused meta-prefixed characters bound to incremental
+ search forward or backward to not be recognized if they were typed
+ subsequently.
+
+j. The incremental search code treats key sequences that map to the same
+ functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
+
+k. Fixed a bug in menu-complete that caused it to misbehave with large
+ negative argument.
+
+l. Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
+ at the end of the line.
+
3. New Features in Bash
a. `exec -a foo' now sets $0 to `foo' in an executable shell script without a
f. test/[/[[ have a new -v variable unary operator, which returns success if
`variable' has been set.
+g. Posix parsing changes to allow `! time command' and multiple consecutive
+ instances of `!' (which toggle) and `time' (which have no cumulative
+ effect).
+
+h. Posix change to allow `time' as a command by itself to print the elapsed
+ user, system, and real times for the shell and its children.
+
+j. $((...)) is always parsed as an arithmetic expansion first, instead of as
+ a potential nested command substitution, as Posix requires.
+
+k. A new FUNCNEST variable to allow the user to control the maximum shell
+ function nesting (recursive execution) level.
+
+l. The mapfile builtin now supplies a third argument to the callback command:
+ the line about to be assigned to the supplied array index.
+
+m. The printf builtin has as new %(fmt)T specifier, which allows time values
+ to use strftime-like formatting.
+
+n. There is a new `compat41' shell option.
+
+o. The cd builtin has a new Posix-mandated `-e' option.
+
+p. Negative subscripts to indexed arrays, previously errors, now are treated
+ as offsets from the maximum assigned index + 1.
+
+q. Negative length specifications in the ${var:offset:length} expansion,
+ previously errors, are now treated as offsets from the end of the variable.
+
+r. Parsing change to allow `time -p --'.
+
+s. Posix-mode parsing change to not recognize `time' as a keyword if the
+ following token begins with a `-'. This means no more Posix-mode
+ `time -p'. Posix interpretation 267.
+
+t. There is a new `lastpipe' shell option that runs the last command of a
+ pipeline in the current shell context. The lastpipe option has no
+ effect if job control is enabled.
+
+u. History expansion no longer expands the `$!' variable expansion.
+
+v. Posix mode shells no longer exit if a variable assignment error occurs
+ with an assignment preceding a command that is not a special builtin.
+
+w. Non-interactive mode shells exit if -u is enabled an an attempt is made
+ to use an unset variable with the % or # expansions, the `//', `^', or
+ `,' expansions, or the parameter length expansion.
+
+x. Posix-mode shells use the argument passed to `.' as-is if a $PATH search
+ fails, effectively searching the current directory. Posix-2008 change.
+
4. New Features in Readline
a. The history library does not try to write the history filename in the
b. New bindable variable `completion-display-width' to set the number of
columns used when displaying completions.
+c. New bindable variable `completion-case-map' to cause case-insensitive
+ completion to treat `-' and `_' as identical.
+
+d. There are new bindable vi-mode command names to avoid readline's case-
+ insensitive matching not allowing them to be bound separately.
+
+e. New bindable variable `menu-complete-display-prefix' causes the menu
+ completion code to display the common prefix of the possible completions
+ before cycling through the list, instead of after.

-lib/readline/vi_mode

- - fix multibyte calculation of `physchars' in prompt expansion, to

- Tomohiro Kubota
-
- 9/6
- ---
-subst.c
- - change word_list_split to avoid really bad behavior caused by calling

- to traverse it every time. Keep a pointer to the end of the list and
- and just tack onto it
-
- 9/8

-lib/readline/complete.c
- - change fnprint to calculate the displayed width of a filename in
- the same way as fnwidth
-
-subst.c
- - in verify_substring_values, when expanding ${array[@]:offset}, make
- sure negative offsets count from one greater than the array's
- maximum index so things like ${x[@}: -1} work to give the last element
- (requires fixing array tests)
-
-builtins/common.c

- error occurs
-

- can be redone properly
- - new function _rl_vi_backup, moves point back a character taking
- multibyte locales into account
- - change rl_vi_redo to handle redoing an `a' command specially --
- it should be redone like `i' but after moving forward a character
- - change rl_vi_redo to use _rl_vi_backup to move point backward
- after redoing `i' or `a'
-
-jobs.c
- - new function, delete_old_job (pid), checks whether or not PID is in
- a job in the jobs list. If so, and the job is dead, it just removes
- the job from the list. If so, and the job is not dead, it zeros
- the pid in the appropriate PROCESS so pid aliasing doesn't occur
- - make_child calls delete_old_job to potentially remove an already-used
- instance of the pid just forked from the jobs list if pids have
- wrapped around. Finally fixes the bug reported by Tim Waugh

- sets SIG_HARD_IGNORE if that handler is SIG_IGN
- - call GETORIGSIG from initialize_traps, get_original_signal, and
- set_signal
-
-jobs.c
- - in wait_for, if the original SIGINT handler is SIG_IGN, don't set
- the handler to wait_sigint_handler. This keeps scripts started in

- on SIGCHLD. Fixes debian bug #483016 reported by Miroslav Rudisin
- <miero@atrey.karlin.mff.cuni.cz>
- - run_sigchld_trap is no longer static, so the trap code in trap.c
- can call it

- set to IMPOSSIBLE_TRAP_HANDLER
- - in trap_handler, don't reset the SIGCHLD trap handler to trap_handler
- if MUST_REINSTALL_SIGHANDLERS is defined
- - new function, set_impossible_sigchld_handler, sets the trap string
- associated with SIGCHLD to IMPOSSIBLE_TRAP_HANDLER; used as a sentinel
- by run_sigchld_trap and maybe_set_sigchld_handler

- path. Rest of fix for bug from Mike Frysinger <vapier@gentoo.org>
- - fix assignment of newline breaks (inv_lbreaks) to correctly account

-parse.y
- - when using the |& construct with a simple command preceding it, add
- the implicit redirection to the simple command's redirection list,
- since the redirections associated with the command struct are never
- executed. Fixes bug reported by Matt Zyzik <Matt@ice.filescope.com>

-execute_cmd.c
- - in execute_case_command, if ;& is used with no following pattern
- list, make sure we don't reference a NULL pointer. Bug report and
- fix from Clark Jian Wang <dearvoid@gmail.com>
-
-parse.y
- - make parser_state global, so other files can use it
- - command_word_acceptable now returns non-zero if PST_REDIRLIST bit
- set in parser_state, so we accept assignment statements and
- perform alias expansion. Fix for bug reported by Vincent
- Lefevre <vincent@vinc17.org> (2/24/2009)
-
-parser.h
- - add PST_REDIRLIST flag, notes that parser is currently parsing a
- redirection list preceding a simple command
-
-make_cmd.c
- - make_simple_command now turns on PST_REDIRLIST in parser_state when
- creating a new simple command
- - make_simple_command turns off PST_REDIRLIST in parser_state if it
- adds a non-redirection to the command it's building
- - clean_simple_command turns off PST_REDIRLIST to make sure it's off
-
-subst.c
- - new flag for param_expand: PF_IGNUNBOUND, means to not exit if the
- variable is unbound even if `set -u' is enabled
- - change param_expand to not call err_unboundvar if the `pflags'
- argument has the PF_IGNUNBOUND bit set
- - parameter_brace_expand_word now takes an extra `pflags' argument to
- pass down to param_expand; changed callers
- - changed call to parameter_brace_expand_word in parameter_brace_expand
- to add PF_IGNUNBOUND flag so ${@:-foo} doesn't cause the shell to
- exit (but ${@} does) when there are no positional parameters. Fixes
- Debian bug 519165 from Dan Jacobson <jidanni@jidanni.org>
-
-parse.y
- - add code to parse_comsub to allow here-documents within command

-subst.c
- - string_list_dollar_at now checks for Q_PATQUOTE, which getpattern()
- uses to denote Q_DOUBLE_QUOTES (?). Fixes a=abcd echo "${a#$*}"
- when IFS= and args are `a b' as noted by Stephane Chazleas
- <stephane_chazelas@yahoo.fr>
- - param_expand now checks for Q_PATQUOTE and treats it identically
- to Q_DOUBLE_QUOTES when expanding $*
- - expand_word_unsplit now sets W_NOSPLIT in the flags of the word it
- passes to expand_word_internal if $IFS is NULL
- - expand_word_leave_quoted now sets expand_no_split_dollar_star and
- the W_NOSPLIT bit in the word flags before calling
- expand_word_internal if $IFS is NULL, just like expand_word_unsplit.
- It is now virtually identical to expand_word_unsplit. Rest of fix for

- is larger than the maximum
- - add cache of last array referenced and last array element referenced;
- use in array_reference to optimize case of sequential access;
- invalidated where necessary in other functions
- - array_rshift needs to set max_index to 0 if the array was empty
- before shifting in the new element 0
- - array_shift needs to use element_index(a->head->prev) to set the
- max_index, not a simple decrement, to deal with sparse arrays

-bashline.c

-subst.c
- - in pat_subst.c, make sure to copy one character from the input
- string in the case of a null pattern match, since we substitute
- on the null match and then increment past the current character.
- Not doing this means that each character of the original string
- is replaced because of the null matches. Fixes debian bug

-builtins/exec.def
- - catch return value from shell_execve; don't print duplicate error
- message if return value is EX_NOTFOUND. Make sure exit status
- from exec is 127 if command is not found
-
-execute_cmd.c
- - fix typo (`saved_redirects' should be `saved redirects') in
- execute_function_or_builtin `command exec' case. Typo caused
- too much of the unwind-protect stack to be discarded
- - in same execute_function_or_builtin case, don't discard the
- `saved redirects' frame unconditionally; only discard it if
- saved_redirects is non-null in the `command exec' case. Fixes
- sh -c 'command exec; exit 1' hanging bug uncovered by FreeBSD
- sh test cases
-

- -----
-subst.c
- - when in posix mode, shell should not exit if a variable assignment
- error (e.g., assigning to readonly variable) occurs preceding a
- command that is not a special builtin. Fixes bug uncovered by
- FreeBSD sh test cases
- - when in posix mode, the ${!?} and ${!#} expansions are not indirect
- expansions, but posix word expansions involving the `!' variable
-
-parse.y
- - fix parse_comsub so that it does not skip backslash-newline when
- parsing a comment
-
- 10/19
- -----
-subst.c
- - fix parameter_brace_expand so that an attempt to use the % or #
- expansions on an unset variable with -u set will cause a non-
- interactive shell to abort. Posix change
- - fix parameter_brace_expand so that an attempt to use pattern
- substitution or case modification expansions on an unset variable
- with -u set will cause and unbound variable error and make a
- non-interactive shell abort
- - change parameter_brace_expand_length to return INTMAX_MIN if a
- positional parameter is unset and -u is set
- - if parameter_brace_expand_length returns INTMAX_MIN when -u is set,
- treat it as an unbound variable error and make a non-interactive
- shell abort. Posix change
- - change parameter_brace_expand_length to return INTMAX_MIN if an
- implicit reference to array[0] is made ${#array} and array[0] is
- not set when -u is set
-

- match_list_index by match_list_size as long as it's < 0. Fixes
- bug reported by jeenuv@gmail.com
-
-braces.c
- - make mkseq() take intmax_t arguments for sequence start and end
- and make sure it's passed intmax_t values. Fixes bug reported by

-
-sig.c
- - if termsig_handler is called when terminate_immediately == 1,
- assume we're being called as a signal handler and set
- history_lines_this_session to 0 to inhibit history file being
- written on shell exit. Fixes long-standing bug most recently
- observed by Andreas Schwab <schwab@linux-m68k.org>

-redir.c
- - add_undo_close_redirect now returns int, 0 on success, non-zero on
- failure. Currently always succeeds
- - new macro REDIRECTION_ERROR to make do_redirection_internal return
- value of errno
- - change do_redirection_internal to call REDIRECTION_ERROR after
- saving file descriptor and make do_redirection_internal return error
- if add_undo_redirect or add_undo_close redirect fails. This makes
- failure to save a file descriptor a redirection error and the shell
- behaves appropriately. Fixes bug reported by Eric Blake
- <eblake@redhat.com>
-
-bashline.c
- - modify bash_forward_shellword to correctly handle quoted strings,
- especially if point is in a quoted string when function is invoked.

-
-lib/readline/vi_mode.c
- - change _rl_vi_append_forward to call _rl_forward_char_internal to
- set rl_point, instead of calling rl_forward_char. When at the end

-This document details the changes between this version, bash-4.2-alpha,
-and the previous version, bash-4.1-release.
-1. Changes to Bash
-
-a. Fixed a bug in the parser when processing alias expansions containing
- quoted newlines.
-
-b. Fixed a memory leak in associative array expansion.
-
-c. Fixed a bug that caused quoted here-strings to be requoted when printed.
-
-d. Fixed a bug in arithmetic expansion that caused the index in an array
- expansion to be evaluated twice under certain circumstances.
-
-e. Fixed several bugs with the expansion and display of variables that have
- been given attributes but not values and are technically unset.
-
-f. Fixed a bug that caused core dumps when using filename completion that
- expands to a filename containing a globbing character.
-
-g. Fixed a bug that caused assignment statements preceding a special builtin
- when running in Posix mode to not persist after the builtin completed
- when the special builtin was executed in a shell function without any
- local variables.
-
-h. Fixed a bug that caused a command to remain in the hash table even after
- `hash command' did not find anything if there was already an existing
- hashed pathname.
-
-i. Fixed several bugs caused by executing unsafe functions from a signal
- handler in the cases where a signal handler is executed immediately
- rather than setting a flag for later execution.
-
-j. Fixed a bug that caused some internal flag variables to be set
- incorrectly if `read -t' timed out.
-
-k. Fixed a Posix compatibility issue by making sure that a backslash escaping
- a `}' within a double-quoted ${...} parameter expansion is removed as part
- of the parameter expansion.
-
-l. Fixed a bug that caused execution of a trap to overwrite PIPESTATUS.
-
-m. Fixed a bug that caused here documents to not be displayed correctly
- when attached to commands inside compound commands.
-
-n. Fixed a bug that caused the printf builtin to use the wrong precision
- when using the `*' modifier.
-
-o. Fixed a bug that caused an arriving SIGCHLD to interrupt output functions
- like those invoked by echo or printf.
-
-p. Changed to use a more robust mechanism than eaccess(2) when test is
- checking filenames for execution permission.
-
-q. Fixed a bug that caused spurious semicolons to be added into the command
- history in certain cases.
-
-r. Fixed a bug that caused the shell to free non-allocated memory when
- unsetting element 0 of an associative array after it was assigned
- implicitly.
-
-s. Fixed a bug that could cause the shell to dump core if using the `v'
- vi editing command on a multi-line command.
-
-t. Fixed a bug that left FIFOs opened by process substitutions open long
- enough to potentially cause file descriptor exhaustion when running a
- shell function or shell builtin.
-
-u. Fixed a bug that caused the history expansion functions to not recognize
- process substitution or extended glob patterns as single words.
-
-v. Fixed a bug that caused restricted shells to set a restricted command's
- exit status incorrectly.
-
-w. Fixed a bug that caused bash to ignore the wrong set of filenames when
- completing a command using the `complete-filename' readline command.
-
-x. Fixed a bug that caused a -PID argument following a -s sig or -n sig to
- not be interpreted as a signal specification.
-
-y. Changed posix-mode behavior of a parse error in a `.' script or `eval'
- command to exit the shell under Posix-specified conditions. Previous
- versions printed a warning.
-
-z. Fixed a bug in \W prompt expansion that resulted in incorrect expansion
- in the event of overlapping strings.
-
-aa. Fixed a bug that caused the := parameter expansion operator to return the
- wrong value as the result of the expansion.
-
-bb. When in Posix mode, a single quote is not treated specially in a
- double-quoted ${...} expansion, unless the expansion operator is
- # or % or the non-Posix `//', `^', and `,'. In particular, it does
- not define a new quoting context. This is from Posix interpretation 221.
-
-cc. Fixed a bug that inadvertently allowed program names containing slashes
- to be entered into the command hash table.
-
-dd. Fixed a bug that caused the select builtin to incorrectly compute the
- display width of the arguments in the presence of multibyte characters.
-
-ee. Fixed a bug that caused bash to not change the xtrace file descriptor if
- BASH_XTRACEFD was found in the shell environment at startup.
-
-ff. Fixed a memory leak in the pattern removal parameter expansion.
-
-gg. Fixed a bug that caused SIGINT to fail to interrupt a nested loop if the
- loop was in a pipeline.
-
-hh. Fixed a problem in $(...) parsing that caused the parser to add an extra
- space to a here-document delimiter if the first word contained a `/'.
-
-ii. Fixed a bug that caused functions defined with the `function' reserved
- word to require braces around the function body.
-
-jj. Fixed a bug that caused bash to dump core when a variable expansion being
- used as an array subscript failed.
-
-kk. Fixed a bug that caused bash to dump core if the case-modification
- expansions were used on a variable with a null value.
-
-ll. Fixed a bug that caused partially-quoted strings to be split incorrectly
- if a variable with a null value was expanded within double quotes.
-
-mm. The pattern substitution word expansion has been sped up dramatically
- when running in a locale with multibyte characters.
-
-nn. Fixed a bug that caused history -a to not write the correct lines to
- the history file if all the new lines in the history list were added
- since the last time the history file was read or written.
-
-oo. Fixed a bug that caused completion of a word with an unclosed `` command
- substitution to set the prompt incorrectly.
-
-pp. Fixed a bug that caused extended globbing patterns in $HISTIGNORE or
- $GLOBIGNORE to be incorrectly scanned.
-
-qq. Fixed a bug caused by closing file descriptors 3-20 on shell startup. The
- shell now sets them to close-on-exec.
-
-rr. Fixed a bug that caused the exit status of `exec file' to be set incorrectly
- if `file' was a directory.
-
-ss. Fixed a bug in the `.' builtin to make a non-interactive posix-mode shell
- exit if the file argument to `.' is not found. Prefixing exec with
- `command' makes the shell not exit. Posix requires this behavior.
-
-tt. Fixed a bug that caused `sh -c 'command exec; exit 1' to hang.
-
-uu. Fixed a bug in $(...) command substitution parsing that caused the shell
- to treat backslash-newline incorrectly when parsing a comment.
-
-vv. Fixed bug that caused brace expansion sequence generation to misbehave
- when supplied integers greater than 2**31 - 1.
-
-ww. Fixed a bug that caused failure to save file descriptors for redirections
- to corrupt shell file descriptors.
-
-xx. Fixed a bug that caused bash-forward-shellword to not correctly handle
- quoted strings.
-
-2. Changes to Readline
-
-a. Fixed a bug that caused the unconverted filename to be added to the list of
- completions when the application specified filename conversion functions.
-
-b. Fixed a bug that caused the wrong filename to be passed to opendir when the
- application has specified a filename dequoting function.
-
-c. Fixed a bug when repeating a character search in vi mode in the case where
- there was no search to repeat.
-
-d. When show-all-if-ambiguous is set, the completion routines no longer insert
- a common match prefix that is shorter than the text being completed.
-
-e. The full set of vi editing commands may now be used in callback mode.
-
-f. Fixed a bug that caused readline to not update its idea of the terminal
- dimensions while running in `no-echo' mode.
-
-h. Fixed a bug that caused readline to dump core if an application called
- rl_prep_terminal without setting rl_instream.
-
-i. Fixed a bug that caused meta-prefixed characters bound to incremental
- search forward or backward to not be recognized if they were typed
- subsequently.
-
-j. The incremental search code treats key sequences that map to the same
- functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
-
-k. Fixed a bug in menu-complete that caused it to misbehave with large
- negative argument.
-
-l. Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
- at the end of the line.
-
-3. New Features in Bash
+1. New Features in Bash
a. `exec -a foo' now sets $0 to `foo' in an executable shell script without a
leading #!.
x. Posix-mode shells use the argument passed to `.' as-is if a $PATH search
fails, effectively searching the current directory. Posix-2008 change.
-4. New Features in Readline
+2. New Features in Readline
a. The history library does not try to write the history filename in the
current directory if $HOME is unset. This closes a potential security
e. New bindable variable `menu-complete-display-prefix' causes the menu
completion code to display the common prefix of the possible completions
before cycling through the list, instead of after.

-
-e. Fixed a bug that caused the shell to set $? incorrectly if a parse error
- occurred in an evaluation context ("eval", trap command, dot script, etc.)
-

-d. Fixed a bug that caused the shell to dump core when listing jobs in the
- `exit' builtin.
-
-e. Fixed several bugs encountered when reading subscripts in associative
- array assignments and expansions.
-
-f. Fixed a bug that under some circumstances caused an associative array to
- be converted to an indexed array.
-
-g. Fixed a bug that caused syntax errors and SIGINT interrupts to not set
- $? to a value > 128.
-
-h. Fixed a bug that caused the shell to remove FIFOs associated with process
- substitution inside shell functions.
-
-i. Fixed a bug that caused terminal attributes to not be reset when the
- `read' builtin timed out.
-
-j. Fixed a bug in brace expansion that caused unwanted zero padding of the
- expanded terms.
-
-k. Fixed a bug that prevented the |& construct from working as intended when
- used with a simple command with additional redirections.
-
-l. Fixed a bug with the case statment ;& terminator that caused the shell to
- dereference a NULL pointer.
-
-m. Fixed a bug that caused assignment statements or redirections preceding
- a simple command name to inhibit alias expansion.
-
-n. Fixed the behavior of `set -u' to conform to the latest Posix interpretation:
- every expansion of an unset variable except $@ and $* will cause the
- shell to exit.
-
-o. Fixed a bug that caused double-quoted expansions of $* inside word
- expansions like ${x#$*} to not expand properly when $IFS is empty.
-
-p. Fixed a bug that caused traps to set $LINENO to the wrong value when they
- execute.
-
-q. Fixed a bug that caused off-by-one errors when computing history lines in

- multiple times.
-
-s. Fixed a bug that caused the shell to attempt to add empty lines to the
- history list when reading here documents.
-
-t. Made some internal changes that dramatically speeds up sequential indexed
- array access.
-
-u. Fixed a bug that caused the shell to write past the end of a string when
- completing a double-quoted string ending in a backslash.
-
-v. Fixed a bug that caused the shell to replace too many characters when a
- pattern match was null in a ${foo//bar} expansion.
-
-w. Fixed bugs in the expansion of ** that caused duplicate directory names
- and the contents of the current directory to be omitted.
-
-x. Fixed a bug that caused $? to not be set correctly when referencing an
- unset variable with set -u and set -e enabled.
-
-y. Fixed a bug caused by executing an external program from the DEBUG trap
- while a pipeline was running. The effect was to disturb the pipeline
- state, occasionally causing it to hang.
-
-z. Fixed a bug that caused the ** glob expansion to dump core if it
- encountered an unsearchable directory.
-
-aa. Fixed a bug that caused `command -v' and `command -V' to not honor the
- path set by the -p option.

-
-hh. Fixed a bug that caused changes made by `compopt' to not persist past the
- completion function in which compopt was executed.

-ii. Fixed a bug that caused the list of hostname completions to not be cleared
- when HOSTNAME was unset.
-
-jj. Fixed a bug that caused variable expansion in here documents to look in
- any temporary environment.
-
-kk. Bash and readline can now convert file names between precomposed and
- decomposed Unicode on Mac OS X ("keyboard" and file system forms,
- respectively). This affects filename completion (using new
- rl_filename_rewrite_hook), globbing, and readline redisplay.
-
-ll. The ERR and EXIT traps now see a non-zero value for $? when a parser
- error after set -e has been enabled causes the shell to exit.
-
-mm. Fixed a bug that in brace expansion that caused zero-prefixed terms to
- not contain the correct number of digits.
-
-nn. Fixed a bug that caused the shell to free non-allocated memory when
- unsetting an associative array which had had a value implicitly assigned
- to index "0".
-
-oo. Fixed a memory leak in the ${!prefix@} expansion.
-
-pp. Fixed a bug that caused printf to not correctly report all write errors.
-
-qq. Fixed a bug that caused single and double quotes to act as delimiters
- when splitting a command line into words for programmable completion.
-
-rr. Fixed a bug that caused ** globbing that caused **/path/* to match every
- directory, not just those matching `path'.
-
-ss. Fixed a bug that caused the shell to dump core when running `help' without
- arguments if the terminal width was fewer than 7 characters.
-
-2. Changes to Readline
-
-a. The SIGWINCH signal handler now avoids calling the redisplay code if
- one arrives while in the middle of redisplay.
-
-b. Changes to the timeout code to make sure that timeout values greater
- than one second are handled better.
-
-c. Fixed a bug in the redisplay code that was triggered by a prompt
- containing invisible characters exactly the width of the screen.
-
-d. Fixed a bug in the redisplay code encountered when running in horizontal
- scroll mode.
-
-e. Fixed a bug that prevented menu completion from properly completing
- filenames.
-
-f. Fixed a redisplay bug caused by a multibyte character causing a line to
- wrap.
-
-g. Fixed a bug that caused key sequences of two characters to not be
- recognized when a longer sequence identical in the first two characters
- was bound.
-
-h. Fixed a bug that caused history expansion to be attempted on $'...'
- single-quoted strings.
-
-i. Fixed a bug that caused incorrect redisplay when the prompt contained
- multibyte characters in an `invisible' sequence bracketed by \[ and
- \].
-
-j. Fixed a bug that caused history expansion to short-circuit after
- encountering a multibyte character.
-
-3. New Features in Bash
-
-a. Here-documents within $(...) command substitutions may once more be
- delimited by the closing right paren, instead of requiring a newline.
-
-b. Bash's file status checks (executable, readable, etc.) now take file
- system ACLs into account on file systems that support them.
-
-c. Bash now passes environment variables with names that are not valid
- shell variable names through into the environment passed to child
- processes.
-
-d. The `execute-unix-command' readline function now attempts to clear and
- reuse the current line rather than move to a new one after the command
- executes.
-
-e. `printf -v' can now assign values to array indices.
-
-f. New `complete -E' and `compopt -E' options that work on the "empty"
- completion: completion attempted on an empty command line.
-
-g. New complete/compgen/compopt -D option to define a `default' completion:
- a completion to be invoked on command for which no completion has been
- defined. If this function returns 124, programmable completion is
- attempted again, allowing a user to dynamically build a set of completions
- as completion is attempted by having the default completion function
- install individual completion functions each time it is invoked.
-
-h. When displaying associative arrays, subscripts are now quoted.
-
-i. Changes to dabbrev-expand to make it more `emacs-like': no space appended
- after matches, completions are not sorted, and most recent history entries
- are presented first.
-
-j. The [[ and (( commands are now subject to the setting of `set -e' and the
- ERR trap.
-
-k. The source/. builtin now removes NUL bytes from the file before attempting
- to parse commands.
-
-l. There is a new configuration option (in config-top.h) that forces bash to
- forward all history entries to syslog.
-
-m. A new variable $BASHOPTS to export shell options settable using `shopt' to
- child processes.
-
-n. There is a new confgure option that forces the extglob option to be
- enabled by default.
-
-o. New variable $BASH_XTRACEFD; when set to an integer bash will write xtrace
- output to that file descriptor.
-
-p. If the optional left-hand-side of a redirection is of the form {var}, the
- shell assigns the file descriptor used to $var or uses $var as the file
- descriptor to move or close, depending on the redirection operator.
-
-q. The < and > operators to the [[ conditional command now do string
- comparison according to the current locale.
-
-r. Programmable completion now uses the completion for `b' instead of `a'
- when completion is attempted on a line like: a $(b c.
-
-s. Force extglob on temporarily when parsing the pattern argument to
- the == and != operators to the [[ command, for compatibility.
-
-t. Changed the behavior of interrupting the wait builtin when a SIGCHLD is
- received and a trap on SIGCHLD is set to be Posix-mode only.

- characters, ignoring delimiters like newline.
-
-4. New Features in Readline
-
-a. New bindable function: menu-complete-backward.
-
-b. In the vi insertion keymap, C-n is now bound to menu-complete by default,
- and C-p to menu-complete-backward.
-
-c. When in vi command mode, repeatedly hitting ESC now does nothing, even
- when ESC introduces a bound key sequence. This is closer to how
- historical vi behaves.
-
-d. New bindable function: skip-csi-sequence. Can be used as a default to
- consume key sequences generated by keys like Home and End without having
- to bind all keys.
-
-e. New application-settable function: rl_filename_rewrite_hook. Can be used
- to rewite or modify filenames read from the file system before they are
- compared to the word to be completed.
-
-f. New bindable variable: skip-completed-text, active when completing in the
- middle of a word. If enabled, it means that characters in the completion
- that match characters in the remainder of the word are "skipped" rather
- than inserted into the line.
-
-g. The pre-readline-6.0 version of menu completion is available as
- "old-menu-complete" for users who do not like the readline-6.0 version.
-
-h. New bindable variable: echo-control-characters. If enabled, and the
- tty ECHOCTL bit is set, controls the echoing of characters corresponding
- to keyboard-generated signals.
-
-i. New bindable variable: enable-meta-key. Controls whether or not readline
- sends the smm/rmm sequences if the terminal indicates it has a meta key
- that enables eight-bit characters.

- in $PATH.
-
-hhh. Fixed a bug that caused the shell to modify the case of a command word

-
-3. New Features in Bash
-
-a. When using substring expansion on the positional parameters, a starting
- index of 0 now causes $0 to be prefixed to the list.
-
-b. The `help' builtin now prints its columns with entries sorted vertically
- rather than horizontally.
-
-c. There is a new variable, $BASHPID, which always returns the process id of
- the current shell.
-
-d. There is a new `autocd' option that, when enabled, causes bash to attempt
- to `cd' to a directory name that is supplied as the first word of a
- simple command.
-
-e. There is a new `checkjobs' option that causes the shell to check for and
- report any running or stopped jobs at exit.
-
-f. The programmable completion code exports a new COMP_TYPE variable, set to
- a character describing the type of completion being attempted.
-
-g. The programmable completion code exports a new COMP_KEY variable, set to
- the character that caused the completion to be invoked (e.g., TAB).
-
-h. If creation of a child process fails due to insufficient resources, bash
- will try again several times before reporting failure.
-
-i. The programmable completion code now uses the same set of characters as
- readline when breaking the command line into a list of words.
-
-j. The block multiplier for the ulimit -c and -f options is now 512 when in
- Posix mode, as Posix specifies.
-
-k. Changed the behavior of the read builtin to save any partial input received
- in the specified variable when the read builtin times out. This also
- results in variables specified as arguments to read to be set to the empty
- string when there is no input available. When the read builtin times out,
- it returns an exit status greater than 128.
-
-l. The shell now has the notion of a `compatibility level', controlled by
- new variables settable by `shopt'. Setting this variable currently
- restores the bash-3.1 behavior when processing quoted strings on the rhs
- of the `=~' operator to the `[[' command.
-
-m. The `ulimit' builtin now has new -b (socket buffer size) and -T (number
- of threads) options.
-
-n. The -p option to `declare' now displays all variable values and attributes
- (or function values and attributes if used with -f).
-
-o. There is a new `compopt' builtin that allows completion functions to modify
- completion options for existing completions or the completion currently
- being executed.
-
-p. The `read' builtin has a new -i option which inserts text into the reply
- buffer when using readline.
-
-q. A new `-E' option to the complete builtin allows control of the default
- behavior for completion on an empty line.
-
-r. There is now limited support for completing command name words containing
- globbing characters.
-
-s. Changed format of internal help documentation for all builtins to roughly
- follow man page format.
-
-t. The `help' builtin now has a new -d option, to display a short description,
- and a -m option, to print help information in a man page-like format.
-
-u. There is a new `mapfile' builtin to populate an array with lines from a
- given file.
-
-v. If a command is not found, the shell attempts to execute a shell function
- named `command_not_found_handle', supplying the command words as the
- function arguments.
-
-w. There is a new shell option: `globstar'. When enabled, the globbing code
- treats `**' specially -- it matches all directories (and files within
- them, when appropriate) recursively.
-
-x. There is a new shell option: `dirspell'. When enabled, the filename
- completion code performs spelling correction on directory names during
- completion.
-
-y. The `-t' option to the `read' builtin now supports fractional timeout
- values.
-
-z. Brace expansion now allows zero-padding of expanded numeric values and
- will add the proper number of zeroes to make sure all values contain the
- same number of digits.
-
-aa. There is a new bash-specific bindable readline function: `dabbrev-expand'.
- It uses menu completion on a set of words taken from the history list.
-
-bb. The command assigned to a key sequence with `bind -x' now sets two new
- variables in the environment of the executed command: READLINE_LINE_BUFFER
- and READLINE_POINT. The command can change the current readline line
- and cursor position by modifying READLINE_LINE_BUFFER and READLINE_POINT,
- respectively.
-
-cc. There is a new &>> redirection operator, which appends the standard output
- and standard error to the named file.
-
-dd. The parser now understands `|&' as a synonym for `2>&1 |', which redirects
- the standard error for a command through a pipe.
-
-ee. The new `;&' case statement action list terminator causes execution to
- continue with the action associated with the next pattern in the
- statement rather than terminating the command.
-
-ff. The new `;;&' case statement action list terminator causes the shell to
- test the next set of patterns after completing execution of the current
- action, rather than terminating the command.
-
-gg. The shell understands a new variable: PROMPT_DIRTRIM. When set to an
- integer value greater than zero, prompt expansion of \w and \W will
- retain only that number of trailing pathname components and replace
- the intervening characters with `...'.
-
-hh. There are new case-modifying word expansions: uppercase (^[^]) and
- lowercase (,[,]). They can work on either the first character or
- array element, or globally. They accept an optional shell pattern
- that determines which characters to modify. There is an optionally-
- configured feature to include capitalization operators.
-
-ii. The shell provides associative array variables, with the appropriate
- support to create, delete, assign values to, and expand them.
-
-jj. The `declare' builtin now has new -l (convert value to lowercase upon
- assignment) and -u (convert value to uppercase upon assignment) options.
- There is an optionally-configurable -c option to capitalize a value at
- assignment.
-
-kk. There is a new `coproc' reserved word that specifies a coprocess: an
- asynchronous command run with two pipes connected to the creating shell.
- Coprocs can be named. The input and output file descriptors and the
- PID of the coprocess are available to the calling shell in variables
- with coproc-specific names.

-4. New Features in Readline
-
-a. A new variable, rl_sort_completion_matches; allows applications to inhibit
- match list sorting (but beware: some things don't work right if
- applications do this).
-
-b. A new variable, rl_completion_invoking_key; allows applications to discover
- the key that invoked rl_complete or rl_menu_complete.
-
-c. The functions rl_block_sigint and rl_release_sigint are now public and
- available to calling applications who want to protect critical sections
- (like redisplay).
-
-d. The functions rl_save_state and rl_restore_state are now public and
- available to calling applications; documented rest of readline's state
- flag values.
-
-e. A new user-settable variable, `history-size', allows setting the maximum
- number of entries in the history list.
-
-f. There is a new implementation of menu completion, with several improvements
- over the old; the most notable improvement is a better `completions
- browsing' mode.
-
-g. The menu completion code now uses the rl_menu_completion_entry_function
- variable, allowing applications to provide their own menu completion
- generators.
-
-h. There is support for replacing a prefix of a pathname with a `...' when
- displaying possible completions. This is controllable by setting the
- `completion-prefix-display-length' variable. Matches with a common prefix
- longer than this value have the common prefix replaced with `...'.
-
-i. There is a new `revert-all-at-newline' variable. If enabled, readline will
- undo all outstanding changes to all history lines when `accept-line' is
- executed.

- 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.

- process substitution.
-
-c. Fixed problems with cross-compiling originating from inherited environment
- variables.
-
-d. Added write error reporting to printf builtin.

- 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

- 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.

- 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 several redisplay problems with multibyte characters, all having to
- do with the different code paths and variable meanings between single-byte
- and multibyte character redisplay.
-
-c. Fixed a problem with key sequence translation when presented with the
- sequence \M-\C-x.
-
-d. Fixed a problem that prevented the `a' command in vi mode from being

-f. Fixed a problem that caused readline to initialize with an incorrect idea
- of whether or not the terminal can autowrap.
-
-g. 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 problem with the callback interface that caused it to fail when
- using multi-character keyboard macros.
-
-m. 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.

- 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 to accessing the current
- pipeline while in the middle of modifying it.

- 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.

- 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.

- when not using subscript syntax.
-
-d. A few changes to configure.in to remove calls to obsolete or outdated
- macros.
-
-e. Make sure changes to variables bash handles specially (e.g., LC_ALL) are
- made when the variable is set in the temporary environment to a command.
-
-f. 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 bug that caused incorrect word splitting in a function when IFS
- was declared local, then unset.
-
-l. Fixed a problem with the `kill' builtin that prevented sending signals
- to a process group under certain circumstances when providing a pid < 0.
-
-m. When in POSIX mode, `pwd' now checks that the value it prints is the same

-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. When in POSIX mode, the `v' command in vi editing mode simply invokes vi
- on the current command, rather than checking $FCEDIT and $EDITOR.
-
-s. Fixed a small memory leak in the pathname canonicalization code.
-
-t. Fixed a bug that caused the expanded value of a $'...' string to be
- incorrectly re-quoted if it occurred within a double-quoted ${...}
- parameter expansion.
-
-u. Restored default emacs-mode key binding of M-TAB to dynamic-complete-history.
-
-v. Fixed a bug that caused core dumps when interrupting loops running builtins
- on some systems.
-
-w. Make sure that some of the functions bash provides replacements for are
- not cpp defines.
-
-x. 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. The `change-case' command now correctly changes the case of multibyte
- characters.
-
-b. Changes to the shared library construction scripts to deal with Windows
- DLL naming conventions for Cygwin.
-
-c. Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
- SIGWINCH.
-
-d. Fixed the non-incremental search code in vi mode to dispose of any current
- undo list when copying a line from the history into the current editing
- buffer.
-
-e. The variable assignment code now ignores whitespace at the end of lines
- when assigning to boolean variables.
-
-f. The `C-w' binding in incremental search now understands multibyte
- characters.
-
-3. New Features in Bash
-
-a. A new configuration option, `--enable-strict-posix-default', which will
- build bash to be POSIX conforming by default.
-
-4. New Features in Readline
-
-a. If the rl_completion_query_items is set to a value < 0, readline never
- asks the user whether or not to view the possible completions.

-------------------------------------------------------------------------------
-This document details the changes between this version, bash-3.1-alpha1,
-and the previous version, bash-3.0-release.

-
-b. Fixed a problem that caused tilde expansion to not be performed before

- containing multibyte characters.
-
-e. Fixed a bug that caused bash to not pass the correct flags for signal
- disposition to child processes.

- extended pattern matching.
-
-l. Fixed the brace expansion code to handle characters whose value exceeds 128.

-
-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 \<newline> to be removed when parsing a $'...'
- construct.
-
-mm. A shell whose name begins with `-' will now be a restricted shell if the
- remainder of the name indicates it should be restricted.
-
-nn. Fixed a bug that could cause a core dump if FUNCNAME were changed or unset
- during a function's execution.
-
-oo. Fixed a bug that caused executing a `return' in a function to not execute
- a RETURN trap. The RETURN trap is inherited by shell functions only if
- function tracing is globally enabled or has been enabled for that function.
-
-pp. Fixed cases where var[@] was not handled exactly like var, when var is a
- scalar variable.
-
-qq. Fixed a bug that caused the first character after a SIGINT to be discarded
- under certain circumstances.
-
-rr. Fixed exit status code so that a suspended job returns 128+signal as its
- exit status (preventing commands after it in `&&' lists from being
- executed).
-
-ss. Fixed a bug that caused the shell parser state to be changed by executing
- a shell function as a result of word completion.
-
-tt. 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 \<newline> 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 that caused a core dump while decoding \W escapes in PS1 if
- PWD was unset.
-
-eee. Fixed a bug in `read' that counted internal quoting characters for the
- purposes of `read -n'.
-
-fff. 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 a bug that caused multiliine prompts to be wrapped and displayed
- incorrectly.
-
-b. Fixed a bug that caused ^P/^N in emacs mode to fail to display the current
- line correctly.
-
-c. Fixed a problem in computing the number of invisible characters on the first
- line of a prompt whose length exceeds the screen width.
-
-d. 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

-
-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.
-

-and the previous version, bash-3.0-beta1.
-
-1. Changes to Bash
-
-a. Fixed a bug that caused incorrect behavior when referecing element 0 of

- 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.

- 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

-
-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

- 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.
-
-------------------------------------------------------------------------------

-
-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. Fixes to process group synchronization code so that every child process
- attempts to set the terminal's process group; fixes some synchronization
- problems on Linux kernels that schedule the child to always run before
- the parent.

- compliance.
-
-e. Fixed a couple of core dumps in the pattern removal code.

- arrays.
-
-g. Parser errors and other errors that result in the shell exiting now cause

- 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

- character of $IFS was not a space.
-
-x. Fixed a slight cosmetic problem when printing commands containing a
- `>&word' redirection.
-
-y. Fixed a problem that could cause here documents to not be created correctly
- if the system temporary directory did not allow writing.
-
-2. Changes to Readline
-
-a. Change to history expansion functions to treat `^' as equivalent to word
- one, as the documention states.
-
-b. 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().

- 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
- <blank>, 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. Fixes to avoid core dumps because of null pointer references in the
- multibyte character code.
-
-b. Fix to avoid infinite recursion caused by certain key combinations.
-
-c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
-
-d. Readline no longer tries to read ahead more than one line of input, even
- when more is available.
-
-e. 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()

-
-1. Changes to Bash
-
-a. Fixed an off-by-one error in the function that translates job
- specifications.
-

- $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.

- 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.
-
-------------------------------------------------------------------------------

-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
- <ctype.h>.
-
-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
- <ctype.h>.
-
-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<x' where 4242 is an out-of-range
- file descriptor).
-
-cc. `printf', `echo -e', and the $'...' code now process only two hex digits
- after a `\x' escape sequence for compatibility with other shells, and
- the documentation was changed to note that the octal and hex escape
- sequences result in an eight-bit value rather than strict ASCII.
-
-2. Changes to Readline
-
-a. The completion code now attempts to do a better job of preserving the
- case of the word the user typed if ignoring case in completions.
-
-b. Readline defaults to not echoing the input and lets the terminal
- initialization code enable echoing if there is a controlling terminal.
-
-c. The key binding code now processes only two hex digits after a `\x'
- escape sequence, and the documentation was changed to note that the
- octal and hex escape sequences result in an eight-bit value rather
- than strict ASCII.
-
-3. New Features in Bash
-
-a. 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'
-
-b. `ulimit' now prints the option letter associated with a particular
- resource when printing more than one limit.
-
-c. `ulimit' prints `hard' or `soft' when a value is not `unlimited' but is
- one of RLIM_SAVED_MAX or RLIM_SAVED_CUR, respectively.
-
-4. New Features in Readline
-
-a. 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 document details the changes between this version, bash-2.05a-alpha1,
-and the previous version, bash-2.05-release.
-
-1. Changes to Bash
-
-a. Better checks in the redirection code for write errors.
-

-c. System-specific configuration changes for: Interix, OpenBSD, FreeBSD,
- MacOS X.
-
-d. Some more `const' cleanups through the code.
-
-e. Fixed a typo in the /dev/fd redirection code, better checks for valid
- numeric fds in /dev/fd.
-
-f. Fixed many parts of the shell to handle integer overflow more gracefully
- and to do more stringent checks for valid numbers.
-
-g. Fixed mksignames to include config.h.
-
-h. Fixed an uninitialized variable problem that could cause the shell to core
- dump when replacing characters in a string.
-
-i. New mechanism for updating the patch level when official patches are
- released (patchlevel.h).
-
-j. configure.in changed to no longer require external files _distribution and
- _patchlevel.
-

- `bash -i filename'.
-
-l. Fixed printf builtin conversion error handling to be POSIX.2-conformant.
-
-m. autoconf-2.52 is now used to build configure; autoconf-2.50 or newer is
- required. Some of the bash-specific macros were removed, since they are
- now standard.
-
-n. Startup files and files read with source or `.' are no longer required to
- be regular files.
-
-o. Fixed core dump in builtin printf when user-supplied precision or field
- width is 0.
-
-p. Fixed builtin printf to treat a negative field width as a positive field
- width with left-justification.
-
-r. New unwind-protect implementation from Paul Eggert.
-
-s. Fixed an inadvertently-unclosed comment in the bash completion code that
- caused programmable completions to not add trailing slashes or spaces to
- completions.
-
-t. Fixed the process substitution code to cope better when stdin is closed.
-
-v. Fixes, mostly from Paul Eggert, for a few possible buffer overflows in
- the shell.
-
-w. Fixes from Paul Eggert to avoid most of the type casts in the shell code,
- and use more appropriate types for a number of variables.
-
-x. Command substition no longer inherits the DEBUG trap.
-
-y. Some fixes to the process substition code on machines without /dev/fd so
- that named pipes are not removed inappropriately.
-
-z. The loadable `getconf' builtin is now much more complete, and will become
- part of the shell in the future.
-
-aa. The select command no longer terminates on a `return', so it can be used
- to return from an enclosing function (as ksh does it).
-
-bb. Fixed the extended pattern matching code to behave better when presented
- with incorrectly-formed patterns.
-
-cc. Some changes were made with the intent of making cross-compilation easier.
-
-dd. The network code (/dev/tcp and /dev/udp redirections) uses getaddrinfo(3)
- if it's available, which adds support for IPv6.
-
-ee. Subshells of login shells no longer source ~/.bash_logout when they exit.
-
-ff. Fixes so that subshells don't exit inappropriately if the -e option has
- been set.
-
-gg. Restricted shells no longer allow functions to be exported.
-
-hh. Changes to the pattern matching code so extended pattern matching works
- on systems with deficient shared library implementations, like MacOS X.
-
-ii. Better error messages when a script with a leading `#!interp' fails
- to execute because of problems with `interp'.
-
-jj. Fixed `compgen' to handle the `-o default' option better.
-
-kk. Fixed the job control code to force an asynchronous process's standard
- input to /dev/null only if job control is not active.
-
-ll. Fixed a possible infinite recursion problem when `fc ""=abc' (a null
- pattern) is used to re-execute a previous command.
-
-mm. Fixed `declare [-a] var=value' to assign VALUE to element 0 if VAR is an
- array variable. Similarly for `declare [-a] var[N]=value'. This is like
- ksh93.
-
-nn. Fixed a bug that caused `read -a aname' to work even if ANAME had been
- declared readonly.
-
-oo. Fixed a possible integer overflow problem when constructing names for
- temporary files.
-
-2. 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.
-
-3. Changes to Readline
-
-a. More `const' and type casting fixes.
-
-b. Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
- overflow problems.
-
-c. The completion code no longer appends a `/' or ` ' to a match when
- completing a symbolic link that resolves to a directory name, unless
- the match does not add anything to the word being completed. This
- means that a tab will complete the word up to the full name, but not
- add anything, and a subsequent tab will add a slash.
-
-d. Fixed a trivial typo that made the vi-mode `dT' command not work.
-
-e. Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
-
-f. Fixed the tty code so that ^V works more than once.
-
-g. Changed the use of __P((...)) for function prototypes to PARAMS((...))
- because the use of __P in typedefs conflicted g++ and glibc.
-
-4. 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. The incremental search code remembers the last search string and uses
- it if ^R^R is typed without a search string.
-
-------------------------------------------------------------------------------
-This document details the changes between this version, bash-2.05-release,
-and the previous version, bash-2.05-beta2.
-
-1. Changes to Bash
-
-a. Make sure we note that the first line of a multi-line command was not
- saved in the history if the tests for HISTCONTROL succeed, but the
- HISTIGNORE check fails.
-
-b. Fixed a bug in the pattern matching code that caused `[' to be treated
- as a special character inside a `[...]' bracket expression.
-
-c. Fixed a bug in the pattern matching code that caused `]' to terminate
- a bracket expression even if it was the first character after the `['
- (or a leading `!' or `^').
-
-d. Made a small change to report a more user-friendly error message if
- execve(2) fails because of an error with the interpreter in a script
- with a leading `#! interpreter'.
-
-e. If the OS does not support an exec(2) magic number of `#!', make sure we
- have a non-null interpreter name before attempting to execute it.
-
-f. Fixed a bug that caused the shell process to end up in a different
- process group than the controlling terminal if a job-control shell was
- run with `exec' in the startup files.
-
-g. When started in POSIX mode, either by `bash --posix', `bash -o posix', or
- `sh', $SHELLOPTS includes `posix' and POSIXLY_CORRECT is set.
-
-h. Fixed a problem that caused the `\W' prompt string escape sequence to
- expand to nothing when $PWD was `//'.
-
-i. The `bashbug' shell script no longer uses $(...) command substitution.
-
-j. When `set' is invoked without options in POSIX mode, it no longer prints
- the names and definitions of shell functions.
-
-2. Changes to Readline
-
-a. rl_set_paren_blink_timeout() is now documented.
-
-b. Corrected history.3 man page: `$' is not in the default value of
- history_word_delimiters.
-
-c. If a hook function assigned to rl_event_hook sets rl_done to a non-zero
- value, rl_read_key() now immediately returns '\n' (which is assumed to
- be bound to accept-line).
-
-3. New Features in Bash
-
-a. The `>&word' redirection now works in POSIX mode as it does by default,
- since POSIX.2 leaves it unspecified.
-
-------------------------------------------------------------------------------

- 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<file' is as if the `command' had been omitted.
-
-pp. ${foo[@]} and ${foo[*]} now work as in ksh93 if `foo' is not an array
- variable.
-
-qq. ${#foo[X]}, where X is 0, @, or *, now work as in ksh93 if `foo' is not
- an array variable.
-
-rr. The shell's idea of an absolute pathname now takes into account a
- possible drive specification on Cygwin and other Windows systems.
-
-ss. Fixed a bug which caused incorrect parsing of some multi-character
- constructs if they were split across input lines with backslash-newline
- line continuation.
-
-tt. Fixed a bug that caused restricted shell mode to be set inappropriately
- when trying to execute a shell script without a leading `#!'.
-
-uu. Shell function definitions no longer require that the body be a group
- command ( {...} ), as POSIX.2 requires.
-
-vv. The `cd' and `pwd' builtins now process symlinks in pathnames internally
- and should require many fewer calls to getcwd().
-
-ww. Fixed a bug that caused a pipeline's process group to be set incorrectly
- if one of the pipeline elements contained a command substitution.
-
-xx. Fixed a bug that caused core dumps when expanding the value of HISTIGNORE.
-
-yy. The output of `set' is now quoted using $'...' so invisible characters are
- displayed as escape sequences.
-
-zz. Fixed the help text for `unset', since PATH and IFS may both be unset.
-
-aaa. The shell no longer puts directory names into the command hash table.
-
-bbb. Fixed a bug in `read' that caused it to occasionally free memory twice if
- it was interrupted after reading a large amount of data.
-
-ccc. Assignment statements that attempt to assign values to readonly variables
- now cause the command to return an error status.
-
-ddd. Fixed a bug that could cause incorrect output if a $(<file) construct was
- interrupted.
-
-eee. GROUPS and FUNCNAME now return an error status when assignment is
- attempted, but may be unset (in which case they lose their special
- properties). In all respects except unsetting, they are readonly.
-
-fff. The string-to-integer conversion code now ignores trailing whitespace in
- the string, even if strtol(3) does not.
-
-ggg. The tcsh magic-space function now does a better job of inserting the
- space close to where the point was before the history expansion, rather
- than just appending it.
-
-hhh. Fixed a bug which caused a file sourced from an interactive shell to
- fill up the jobs table if it ran lots of jobs.
-
-iii. Fixed a bug in the parameter pattern substitution code to avoid infinite
- recursion on zero-length matches.
-
-2. Changes to Readline
-
-a. When setting the terminal attributes on systems using `struct termio',
- readline waits for output to drain before changing the attributes.
-
-b. A fix was made to the history word tokenization code to avoid attempts to
- dereference a null pointer.
-
-c. Readline now defaults rl_terminal_name to $TERM if the calling application
- has left it unset, and tries to initialize with the resultant value.
-
-d. Instead of calling (*rl_getc_function)() directly to get input in certain
- places, readline now calls rl_read_key() consistently.
-
-e. Fixed a bug in the completion code that allowed a backslash to quote a
- single quote inside a single-quoted string.
-
-f. rl_prompt is no longer assigned directly from the argument to readline(),
- but uses memory allocated by readline. This allows constant strings to
- be passed to readline without problems arising when the prompt processing
- code wants to modify the string.
-
-g. Fixed a bug that caused non-interactive history searches to return the
- wrong line when performing multiple searches backward for the same string.
-
-h. Many variables, function arguments, and function return values are now
- declared `const' where appropriate, to improve behavior when linking with
- C++ code.
-
-i. The control character detection code now works better on systems where
- `char' is unsigned by default.
-
-j. The vi-mode numeric argument is now capped at 999999, just like emacs mode.
-
-k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been
- replaced with a set of specific prototyped typedefs, though they are
- still in the readline header files for backwards compatibility.
-
-m. Nearly all of the (undocumented) internal global variables in the library
- now have an _rl_ prefix -- there were a number that did not, like
- screenheight, screenwidth, alphabetic, etc.
-
-n. The ding() convenience function has been renamed to rl_ding(), though the
- old function is still defined for backwards compatibility.
-
-o. The completion convenience functions filename_completion_function,
- username_completion_function, and completion_matches now have an rl_
- prefix, though the old names are still defined for backwards compatibility.
-
-p. The functions shared by readline and bash (linkage is satisfied from bash
- when compiling with bash, and internally otherwise) now have an sh_ prefix.
-
-q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so
- that the `soname' contains only the major version number rather than the
- major and minor numbers.
-
-r. Fixed a redisplay bug that occurred when the prompt spanned more than one
- physical line and contained invisible characters.
-
-3. 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
-
-4. New Features in Readline
-
-a. The blink timeout for paren matching is now settable by applications.
-
-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.

-
-e. A bug was fixed that, under obscure circumstances, could confuse the
- parser when a shell function was run by the programmable completion code.
-
-f. A bug was fixed in the ulimit builtin for systems not using getrlimit().
-
-g. The execution code now propagates the correct exit status back to the rest
- of the code if the return value of a subshell command was being inverted.
- Some new test cases for inverting return values with the `!' reserved
- word have been added.
-
-h. Negative exponents in the arithmetic evaluation of v**e now return an
- evaluation error.
-
-i. A bug that caused bash to check the wrong process in a pipeline for

- commands was fixed.
-
-4. A couple of memory leaks in the programmable completion code were fixed.
-
-5. A bug that could cause a core dump by freeing memory twice during a call
- to `eval' if `set -u' had been enabled and an undefined variable was
- referenced was fixed.

-
-i. If the shell exits while in a function, make sure that any trap on EXIT
- doesn't think the function is still executing.
-
-j. Bashbug now tries harder to find a usable editor if $EDITOR is not set,
- rather than simply defaulting to `emacs'.
-
-k. Changes to the scripts that guess and canonicalize the system type, from
- the latest `automake' distribution via Debian.
-
-l. When using named pipes for process substitution, make sure the file
- descriptors opened for reading are set to non-blocking mode.
-
-m. Fixed a bug that caused termination of pipelines that are killed by a
- signal to not be reported in some cases.
-
-n. When not in literal-history mode, shell comment lines are not added to
- the history list.
-
-o. When running in POSIX.2 mode, bash no longer performs word splitting on
- the expanded value of the word supplied as the filename argument to
- redirection operators.
-
-p. The prompt string decoding code now backslash-quotes only characters that
- are special within double quotes when expanding the \w and \W escape
- sequences.
-
-q. Fixed a bug in the prompt decoding code that could cause a non-interactive
- shell to seg fault if `\u' was used in PS4 and the shell was in xtrace
- mode.
-
-r. Fixed a bug that caused function definitions to be printed with any
- redirections that should be attached to the entire function before the

- time signals on systems which support them.
-
-2. Changes to Readline
-
-a. Fixed a problem with the single-quote quoting function that could cause

- the files being completed were in the root directory and visible-stats
- was enabled.
-
-3. New Features in Bash
-
-a. There is a new `rbash.1' manual page, from the Debian release.
-
-b. The `--enable-usg-echo-default' option to `configure' has been renamed to

- 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 \<newline>
- 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.
-

-
-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. Fixed a cosmetic problem in the source that caused the shell to not
- compile if DPAREN_ARITHMETIC was not defined but ARITH_FOR_COMMAND was.
-
-r. Fixed a bug in the here-document code tripped when the file descriptor
- opened to the file containing the text of the here document was the
- same as a redirector specified by the user.
-
-s. Fixed a bug where the INVERT_RETURN flag was not being set for `pipeline'
- in `time ! pipeline'.
-
-t. Fixed a bug with the `wait' builtin which manifested itself when an
- interrupt was received while the shell was waiting for asynchronous
- processes in a shell script.
-
-u. Fixed the DEBUG trap code so that it has the correct value of $?.
-
-v. Fixed a bug in the parameter pattern substitution code that could cause
- the shell to attempt to free unallocated memory if the pattern started
- with `/' and an expansion error occurs.
-
-w. Fixed a bug in the positional parameter substring code that could
- cause the shell to loop freeing freed memory.
-
-x. Fixed a bug in the positional parameter pattern substitution code so
- that it correctly handles null replacement strings with a pattern
- string prefixed with `%' or `#'.
-
-y. The shell no longer attempts to import functions from the environment if
- started with `-n'.
-
-z. Fixed a bug that caused `return' in a command substitution executed in
- a shell function to return from the function in a subshell and continue
- execution.
-
-aa. `hash -p /pathname/with/slashes name' is no longer allowed when the shell
- is restricted.
-
-bb. The wait* job control functions now behave better if called when there
- are no unwaited-for children.
-
-cc. Command substitution no longer unconditionally disables job control in
- the subshell started to run the command.

-a. Fixed a bug in the redisplay code for lines with more than 256 line
- breaks.
-
-b. A bug was fixed which caused invisible character markers to not be
- stripped from the prompt string if the terminal was in no-echo mode.
-
-c. Readline no longer tries to get the variables it needs for redisplay
- from the termcap entry if the calling application has specified its
- own redisplay function. Readline treats the terminal as `dumb' in
- this case.
-
-d. Fixes to the SIGWINCH code so that a multiple-line prompt with escape
- sequences is redrawn correctly.
-
-3. New Features in Bash
-
-a. `bashbug' now accepts `--help' and `--version' options.
-
-b. There is a new `xpg_echo' option to `shopt' that controls the behavior
- of echo with respect to backslash-escaped characters at runtime.
-
-------------------------------------------------------------------------------
-This document details the changes between this version, bash-2.04-alpha1,
-and the previous version, bash-2.04-devel.
-
-1. Changes to Bash
-
-a. Fixed a bug that could cause core dumps when performing substring
- expansion.
-
-b. Shared object configuration changes for: Solaris, OSF/1
-
-c. The POSIX_GLOB_LIBRARY code that uses the POSIX.2 globbing facilities
- for pathname expansion now understands GLOBIGNORE.
-
-d. The code that implements `eval' was changed to save the value of the
- current prompt, so an eval in a shell function called by the programmable
- completion code will not change the prompt to $PS2.
-
-e. Restored the undocumented NON_INTERACTIVE_LOGIN_SHELLS #define to
- config-top.h. If this is defined, all login shells will read the
- startup files, not just interactive and non-interactive started with
- the `--login' option.
-
-f. Fixed a bug that caused the expansion code to occasionally dump core if
- IFS contained characters > 128.
-
-g. Fixed a problem with the grammar so that a newline is not required
- after the `))' in the new-style arithmetic for statement; a semicolon
- may be used as expected.
-
-h. Variable indirection may now reference the shell's special variables.
-
-i. The $'...' and $"..." constructs are now added to the history correctly
- if they contain newlines and command-oriented history is enabled.
-
-j. It is now an error to try to assign a value to a function-local copy
- of a readonly shell variable (declared with the `local' builtin).
-
-2. Changes to Readline
-
-a. The history file code now uses O_BINARY mode when reading and writing
- the history file on cygwin32.
-
-3. New Features in Bash

- is not processed by subsequent parameter expansion.
-
-r. Fixed a parsing bug that caused a single or double quote after a `$$' to
- trigger ANSI C expansion or locale translation.
-
-s. Fixed a bug in the globbing code that caused quoted filenames containing
- no globbing characters to sometimes be incorrectly expanded.

- relies on proper behavior from the C library.
-
-dd. Minor changes were made to allow quoted variable expansions using
- ${...} to be completed correctly if there is no closing `"'.
-
-ee. Changes were made to builtins/Makefile.in so that configuring the shell
- with `--enable-profiling' works right and builtins/mkbuiltins is
- generated.
-
-2. Changes to Readline
-
-a. The version number is now 4.0.
-
-b. There is no longer any #ifdef SHELL code in the source files.
-

- milliseconds.
-
-e. The readline library should be compilable by C++ compilers.
-
-f. The readline.h public header file now includes function prototypes for
- all readline functions, and some changes were made to fix errors in the

- 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.
-
-4. New Features in Readline
-

- 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.

-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'

- 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

-
-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 `./'.

- 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,

- (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-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

- 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).

- 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.

-
-------------------------------------------------------------------------------

- 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.
-

- 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

-
-l. Fixed a problem caused by a recursive call reparsing the value of

- 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 <stdarg.h> 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.

-
-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.

- 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.

- displayed.
-
-r. Fixes were made to the code that handles DEBUG traps so that the trap

- 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. The command-oriented-history code no longer attempts to add `;'
- inappropriately when a newline appears while reading a $(...) command
- substitution.
-
-dd. A bug that caused the shell to dump core when `help --' was executed

- and `shift' on the same set of positional parameters was fixed.
-

-
-ll. The command printing code now handles here documents better when there
- are other redirections associated with the command.

- 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.

- 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.
-

-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. Changes to Readline
-
-a. A bug that caused an extra newline to be printed when the cursor was on
- an otherwise empty line was fixed.
-
-b. An instance of memory being used after it was freed was corrected.
-
-c. The redisplay code now works when the prompt is longer than the screen
- width.
-
-d. `dump-macros' is now a bindable name, as it should have been all along.
-
-e. 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. The completion code now updates the common prefix of matched names
- after FIGNORE processing is done, since any names that were removed
- may have changed the common prefix.
-
-c. Fixed a bug that made messages in MAILPATH entries not work correctly.
-
-d. Fixed a serious documentation error in the description of the new
- ${parameter:offset[:length]} expansion.
-
-e. Fixes to make parameter substring expansion ({$param:offset[:length]})
- work when within double quotes.
-
-f. Fixes to make ^A (CTLESC) survive an unquoted expansion of positional
- parameters.
-
-g. Corrected a misspelling of `unlimited' in the output of `ulimit'.
-
-h. Fixed a bug that caused executable scripts without a leading `#!' to
- occasionally pick up the wrong set of positional parameters.
-
-i. 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.
+This is a terse description of the new features added to bash-4.2 since
+the release of bash-4.1. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. `exec -a foo' now sets $0 to `foo' in an executable shell script without a
+ leading #!.
+
+b. Subshells begun to execute command substitutions or run shell functions or
+ builtins in subshells do not reset trap strings until a new trap is
+ specified. This allows $(trap) to display the caller's traps and the
+ trap strings to persist until a new trap is set.
+
+c. `trap -p' will now show signals ignored at shell startup, though their
+ disposition still cannot be modified.
+
+d. $'...', echo, and printf understand \uXXXX and \UXXXXXXXX escape sequences.
+
+e. declare/typeset has a new `-g' option, which creates variables in the
+ global scope even when run in a shell function.
+
+f. test/[/[[ have a new -v variable unary operator, which returns success if
+ `variable' has been set.
+
+g. Posix parsing changes to allow `! time command' and multiple consecutive
+ instances of `!' (which toggle) and `time' (which have no cumulative
+ effect).
+
+h. Posix change to allow `time' as a command by itself to print the elapsed
+ user, system, and real times for the shell and its children.
+
+j. $((...)) is always parsed as an arithmetic expansion first, instead of as
+ a potential nested command substitution, as Posix requires.
+
+k. A new FUNCNEST variable to allow the user to control the maximum shell
+ function nesting (recursive execution) level.
+
+l. The mapfile builtin now supplies a third argument to the callback command:
+ the line about to be assigned to the supplied array index.
+
+m. The printf builtin has as new %(fmt)T specifier, which allows time values
+ to use strftime-like formatting.
+
+n. There is a new `compat41' shell option.
+
+o. The cd builtin has a new Posix-mandated `-e' option.
+
+p. Negative subscripts to indexed arrays, previously errors, now are treated
+ as offsets from the maximum assigned index + 1.
+
+q. Negative length specifications in the ${var:offset:length} expansion,
+ previously errors, are now treated as offsets from the end of the variable.
+
+r. Parsing change to allow `time -p --'.
+
+s. Posix-mode parsing change to not recognize `time' as a keyword if the
+ following token begins with a `-'. This means no more Posix-mode
+ `time -p'. Posix interpretation 267.
+
+t. There is a new `lastpipe' shell option that runs the last command of a
+ pipeline in the current shell context. The lastpipe option has no
+ effect if job control is enabled.
+
+u. History expansion no longer expands the `$!' variable expansion.
+
+v. Posix mode shells no longer exit if a variable assignment error occurs
+ with an assignment preceding a command that is not a special builtin.
+
+w. Non-interactive mode shells exit if -u is enabled an an attempt is made
+ to use an unset variable with the % or # expansions, the `//', `^', or
+ `,' expansions, or the parameter length expansion.
+
+x. Posix-mode shells use the argument passed to `.' as-is if a $PATH search
+ fails, effectively searching the current directory. Posix-2008 change.
+
+2. New Features in Readline
+
+a. The history library does not try to write the history filename in the
+ current directory if $HOME is unset. This closes a potential security
+ problem if the application does not specify a history filename.
+
+b. New bindable variable `completion-display-width' to set the number of
+ columns used when displaying completions.
+
+c. New bindable variable `completion-case-map' to cause case-insensitive
+ completion to treat `-' and `_' as identical.
+
+d. There are new bindable vi-mode command names to avoid readline's case-

- GNU GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
- The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works. By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users. We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors. 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
-them 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 prevent others from denying you
-these rights or asking you to surrender the rights. Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received. 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.
-
- Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
- For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software. For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
- Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so. This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software. The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable. Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products. If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
- Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary. To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- TERMS AND CONDITIONS
-
- 0. Definitions.
-
- "This License" refers to version 3 of the GNU General Public License.
-
- "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
- "The Program" refers to any copyrightable work licensed under this
-License. Each licensee is addressed as "you". "Licensees" and
-"recipients" may be individuals or organizations.
-
- To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy. The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
- A "covered work" means either the unmodified Program or a work based
-on the Program.
-
- To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy. Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
- To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies. Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
- An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License. If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
- 1. Source Code.
-
- The "source code" for a work means the preferred form of the work
-for making modifications to it. "Object code" means any non-source
-form of a work.
-
- A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
- The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form. A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
- The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities. However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work. For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
- The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
- The Corresponding Source for a work in source code form is that
-same work.
-
- 2. Basic Permissions.
-
- All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met. This License explicitly affirms your unlimited
-permission to run the unmodified Program. The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work. This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
- You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force. You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright. Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
- Conveying under any other circumstances is permitted solely under
-the conditions stated below. Sublicensing is not allowed; section 10
-makes it unnecessary.
-
- 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
- No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
- When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
- 4. Conveying Verbatim Copies.
-
- You may convey 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;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
- You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
- 5. Conveying Modified Source Versions.
-
- You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
- a) The work must carry prominent notices stating that you modified
- it, and giving a relevant date.
-
- b) The work must carry prominent notices stating that it is
- released under this License and any conditions added under section
- 7. This requirement modifies the requirement in section 4 to
- "keep intact all notices".
-
- c) You must license the entire work, as a whole, under this
- License to anyone who comes into possession of a copy. This
- License will therefore apply, along with any applicable section 7
- additional terms, to the whole of the work, and all its parts,
- regardless of how they are packaged. This License gives no
- permission to license the work in any other way, but it does not
- invalidate such permission if you have separately received it.
-
- d) If the work has interactive user interfaces, each must display
- Appropriate Legal Notices; however, if the Program has interactive
- interfaces that do not display Appropriate Legal Notices, your
- work need not make them do so.
-
- A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit. Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
- 6. Conveying Non-Source Forms.
-
- You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
- a) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by the
- Corresponding Source fixed on a durable physical medium
- customarily used for software interchange.
-
- b) Convey the object code in, or embodied in, a physical product
- (including a physical distribution medium), accompanied by a
- written offer, valid for at least three years and valid for as
- long as you offer spare parts or customer support for that product
- model, to give anyone who possesses the object code either (1) a
- copy of the Corresponding Source for all the software in the
- product that is covered by this License, on a durable physical
- medium customarily used for software interchange, for a price no
- more than your reasonable cost of physically performing this
- conveying of source, or (2) access to copy the
- Corresponding Source from a network server at no charge.
-
- c) Convey individual copies of the object code with a copy of the
- written offer to provide the Corresponding Source. This
- alternative is allowed only occasionally and noncommercially, and
- only if you received the object code with such an offer, in accord
- with subsection 6b.
-
- d) Convey the object code by offering access from a designated
- place (gratis or for a charge), and offer equivalent access to the
- Corresponding Source in the same way through the same place at no
- further charge. You need not require recipients to copy the
- Corresponding Source along with the object code. If the place to
- copy the object code is a network server, the Corresponding Source
- may be on a different server (operated by you or a third party)
- that supports equivalent copying facilities, provided you maintain
- clear directions next to the object code saying where to find the
- Corresponding Source. Regardless of what server hosts the
- Corresponding Source, you remain obligated to ensure that it is
- available for as long as needed to satisfy these requirements.
-
- e) Convey the object code using peer-to-peer transmission, provided
- you inform other peers where the object code and Corresponding
- Source of the work are being offered to the general public at no
- charge under subsection 6d.
-
- A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
- A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling. In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage. For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product. A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
- "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source. The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
- If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information. But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
- The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed. Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
- Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
- 7. Additional Terms.
-
- "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law. If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
- When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it. (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.) You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
- Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
- a) Disclaiming warranty or limiting liability differently from the
- terms of sections 15 and 16 of this License; or
-
- b) Requiring preservation of specified reasonable legal notices or
- author attributions in that material or in the Appropriate Legal
- Notices displayed by works containing it; or
-
- c) Prohibiting misrepresentation of the origin of that material, or
- requiring that modified versions of such material be marked in
- reasonable ways as different from the original version; or
-
- d) Limiting the use for publicity purposes of names of licensors or
- authors of the material; or
-
- e) Declining to grant rights under trademark law for use of some
- trade names, trademarks, or service marks; or
-
- f) Requiring indemnification of licensors and authors of that
- material by anyone who conveys the material (or modified versions of
- it) with contractual assumptions of liability to the recipient, for
- any liability that these contractual assumptions directly impose on
- those licensors and authors.
-
- All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10. If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term. If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
- If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
- Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
- 8. Termination.
-
- You may not propagate or modify a covered work except as expressly
-provided under this License. Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
- However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
- Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
- Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
- 9. Acceptance Not Required for Having Copies.
-
- You are not required to accept this License in order to receive or
-run a copy of the Program. Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance. However,
-nothing other than this License grants you permission to propagate or
-modify any covered work. These actions infringe copyright if you do
-not accept this License. Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
- 10. Automatic Licensing of Downstream Recipients.
-
- Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License. You are not responsible
-for enforcing compliance by third parties with this License.
-
- An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations. If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
- You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License. For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
- 11. Patents.
-
- A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based. The
-work thus licensed is called the contributor's "contributor version".
-
- A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version. For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
- Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
- In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement). To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
- If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients. "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
- If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
- A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License. You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
- Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
- 12. No Surrender of Others' Freedom.
-
- If 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 convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all. For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
- 13. Use with the GNU Affero General Public License.
-
- Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work. The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
- 14. Revised Versions of this License.
-
- The Free Software Foundation may publish revised and/or new versions of
-the GNU 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 that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation. If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
- If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
- Later license versions may give you additional or different
-permissions. However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
- 15. Disclaimer of Warranty.
-
- 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.
-
- 16. Limitation of Liability.
-
- IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-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.
-
- 17. Interpretation of Sections 15 and 16.
-
- If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
- END OF TERMS AND CONDITIONS
-
- 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
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- 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 3 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, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
- If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
- <program> Copyright (C) <year> <name of author>
- This program 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, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
- You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
- The GNU General Public License does not permit incorporating your program
-into proprietary programs. If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library. If this is what you want to do, use the GNU Lesser General
-Public License instead of this License. But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

-PREAMBLE
-
-The purpose of this License is to make a manual, textbook, or other
-functional and useful document @dfn{free} in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-
-This License is a kind of ``copyleft'', which means that derivative
-works of the document must themselves be free in the same sense. It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does. But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book. We recommend this License
-principally for works whose purpose is instruction or reference.
-
-@item
-APPLICABILITY AND DEFINITIONS
-
-This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License. Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein. The ``Document'', below,
-refers to any such manual or work. Any member of the public is a
-licensee, and is addressed as ``you''. You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-
-A ``Modified Version'' of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-A ``Secondary Section'' is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document's overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject. (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.) The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-
-The ``Invariant Sections'' are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License. If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant. The Document may contain zero
-Invariant Sections. If the Document does not identify any Invariant
-Sections then there are none.
-
-The ``Cover Texts'' are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License. A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-
-A ``Transparent'' copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters. A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text. A copy that is not ``Transparent'' is called ``Opaque''.
-
-Examples of suitable formats for Transparent copies include plain
-@sc{ascii} without markup, Texinfo input format, La@TeX{} input
-format, @acronym{SGML} or @acronym{XML} using a publicly available
-@acronym{DTD}, and standard-conforming simple @acronym{HTML},
-PostScript or @acronym{PDF} designed for human modification. Examples
-of transparent image formats include @acronym{PNG}, @acronym{XCF} and
-@acronym{JPG}. Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, @acronym{SGML} or
-@acronym{XML} for which the @acronym{DTD} and/or processing tools are
-not generally available, and the machine-generated @acronym{HTML},
-PostScript or @acronym{PDF} produced by some word processors for
-output purposes only.
-
-The ``Title Page'' means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page. For works in
-formats which do not have any title page as such, ``Title Page'' means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.
-
-The ``publisher'' means any person or entity that distributes copies
-of the Document to the public.
-
-A section ``Entitled XYZ'' means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language. (Here XYZ stands for a
-specific section name mentioned below, such as ``Acknowledgements'',
-``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
-of such a section when you modify the Document means that it remains a
-section ``Entitled XYZ'' according to this definition.
-
-The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document. These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-
-@item
-VERBATIM COPYING
-
-You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License. You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-@item
-COPYING IN QUANTITY
-
-If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document's license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover. Both covers must also clearly and legibly identify
-you as the publisher of these copies. The front cover must present
-the full title with all words of the title equally prominent and
-visible. You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-
-It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-
-@item
-MODIFICATIONS
-
-You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it. In addition, you must do these things in the Modified Version:
-
-@enumerate A
-@item
-Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document). You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-@item
-List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-@item
-State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-@item
-Preserve all the copyright notices of the Document.
-
-@item
-Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-@item
-Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-@item
-Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document's license notice.
-
-@item
-Include an unaltered copy of this License.
-
-@item
-Preserve the section Entitled ``History'', Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page. If
-there is no section Entitled ``History'' in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-@item
-Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on. These may be placed in the ``History'' section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-@item
-For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-@item
-Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles. Section numbers
-or the equivalent are not considered part of the section titles.
-
-@item
-Delete any section Entitled ``Endorsements''. Such a section
-may not be included in the Modified Version.
-
-@item
-Do not retitle any existing section to be Entitled ``Endorsements'' or
-to conflict in title with any Invariant Section.
-
-@item
-Preserve any Warranty Disclaimers.
-@end enumerate
-
-If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the
-list of Invariant Sections in the Modified Version's license notice.
-These titles must be distinct from any other section titles.
-
-You may add a section Entitled ``Endorsements'', provided it contains
-nothing but endorsements of your Modified Version by various
-parties---for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-
-You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity. If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-
-The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-
-@item
-COMBINING DOCUMENTS
-
-You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-
-The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy. If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections Entitled ``History''
-in the various original documents, forming one section Entitled
-``History''; likewise combine any sections Entitled ``Acknowledgements'',
-and any sections Entitled ``Dedications''. You must delete all
-sections Entitled ``Endorsements.''
-
-@item
-COLLECTIONS OF DOCUMENTS
-
-You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-
-You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-
-@item
-AGGREGATION WITH INDEPENDENT WORKS
-
-A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an ``aggregate'' if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation's users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-
-If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document's Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-
-@item
-TRANSLATION
-
-Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers. In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-
-If a section in the Document is Entitled ``Acknowledgements'',
-``Dedications'', or ``History'', the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-
-@item
-TERMINATION
-
-You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense, or distribute it is void, and
-will automatically terminate your rights under this License.
-
-However, if you cease all violation of this License, then your license
-from a particular copyright holder is reinstated (a) provisionally,
-unless and until the copyright holder explicitly and finally
-terminates your license, and (b) permanently, if the copyright holder
-fails to notify you of the violation by some reasonable means prior to
-60 days after the cessation.
-
-Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License. If your rights have been terminated and not permanently
-reinstated, receipt of a copy of some or all of the same material does
-not give you any rights to use it.
-
-@item
-FUTURE REVISIONS OF THIS LICENSE
-
-The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation 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. See
-@uref{http://www.gnu.org/copyleft/}.
-
-Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License ``or any later version'' applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation. If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation. If the Document
-specifies that a proxy can decide which future versions of this
-License can be used, that proxy's public statement of acceptance of a
-version permanently authorizes you to choose that version for the
-Document.
-
-@item
-RELICENSING
-
-``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
-World Wide Web server that publishes copyrightable works and also
-provides prominent facilities for anybody to edit those works. A
-public wiki that anybody can edit is an example of such a server. A
-``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
-site means any set of copyrightable works thus published on the MMC
-site.
-
-``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
-license published by Creative Commons Corporation, a not-for-profit
-corporation with a principal place of business in San Francisco,
-California, as well as future copyleft versions of that license
-published by that same organization.
-
-``Incorporate'' means to publish or republish a Document, in whole or
-in part, as part of another Document.
-
-An MMC is ``eligible for relicensing'' if it is licensed under this
-License, and if all works that were first published under this License
-somewhere other than this MMC, and subsequently incorporated in whole
-or in part into the MMC, (1) had no cover texts or invariant sections,
-and (2) were thus incorporated prior to November 1, 2008.
-
-The operator of an MMC Site may republish an MMC contained in the site
-under CC-BY-SA on the same site at any time before August 1, 2009,
-provided the MMC is eligible for relicensing.

-@page
-@heading ADDENDUM: How to use this License for your documents
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-
-@smallexample
-@group
- Copyright (C) @var{year} @var{your name}.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.3
- or any later version published by the Free Software Foundation;
- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
- Texts. A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.
-@end group
-@end smallexample
-
-If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the ``with@dots{}Texts.'' line with this:
-
-@smallexample
-@group
- with the Invariant Sections being @var{list their titles}, with
- the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
- being @var{list}.
-@end group
-@end smallexample
-
-If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.
