+
+bb. Fixed several bugs where bash performed arithmetic evaluation in contexts
+ where evaluation is suppressed.

+
+yy. Fixed a bug that caused tildes to not be escaped in expanded filenames,
+ making them subject to later expansion.
+
+zz. When using the pattern substitution word expansion, bash now runs the
+ replacement string through quote removal, since it allows quotes in that
+ string to act as escape characters. This is not backwards compatible, so
+ it can be disabled by setting the bash compatibility mode to 4.2.
+
+aaa. Fixed the rest of the cases where the shell runs non-allowed code in a
+ signal handler context.
+
+bbb. Fixed a bug that caused spurious DEL characters (\177) to appear in

+
+ccc. Fixed a bug that caused the use of the shell's internal random number

+
+fff. Fixed a bug that caused the `lastpipe' option to corrupt the file
+ descriptor used to read the script.
+
+ggg. Fixed a bug that causes the shell to delete DEL characters in the
+ expanded value of variables used in the same quoted string as variables
+ that expand to nothing.
+
+hhh. Fixed a bug that caused the shell to assign the wrong value from an
+ assignment like (( x=7 )) when `x' was an existing array variable.
+
+iii. Fixed a bug that caused the shell to misbehave when generating sequences
+ and the boundary values overflow an intmax_t.

+ printf %(...)T format overflowed the value accepted by localtime(3).
+
+zzz. Fixed a problem with displaying help topics in two columns when the
+ translated text contained multibyte characters.
+
+aaaa. Fixed a bug with the extended globbing pattern matcher where a `*' was
+ followed by a negated extended glob pattern.
+
+bbbb. Fixed a race condition with short-lived coproc creation and reaping that
+ caused the child process to be reaped before the various coproc shell
+ variables were initialized.
+
+cccc. Fixed a bug where turning off `errexit' in command substitution subshells
+ was not reflected in $SHELLOPTS.
+
+dddd. Partially fixed an inconsistency in how the shell treated shell
+ functions run from an EXIT trap.
+
+eeee. Fixed a bug in how the shell invalidated FIFOs used for process
+ substitution when executing a pipeline (once rather than in every child).
+
+ffff. Fixed a bug that occurred when expanding a special variable ($@, $*)
+ within double quotes and the expansion resulted in an empty string.
+
+gggg. Fixed bugs with executing a SIGCHLD trap handler to make sure that it's
+ executed once per exited child.
+
+hhhh. Fixed a bug that caused `declare' and `test' to find variables that

+ not set.
+

+jjjj. Fixed several problems with globstar expansions (**/**) returning null
+ filenames and multiple instances of the same pathname.
+
+kkkk. Fixed an oversight that did not allow the exit status of `coproc' to
+ be inverted using `!'.
+
+llll. Fixed a bug that caused the -e option to be re-enabled using `set -e'
+ even when executing in a context where -e is ignored.
+
+mmmm. Fixed a (mostly theoretical) bug with input lines longer than SIZE_MAX.
+
+nnnn. Fixed a bug that could result in double evaluation of command
+ substitutions when they appear in failed redirections.
+
+oooo. Fixed a bug that could cause seg faults during `mapfile' callbacks if
+ the callback unsets the array variable mapfile is using.
+
+pppp. Fixed several problems with variable assignments using ${var:=value}
+ when the variable assignment is supposed to have side effects.
+
+qqqq. Fixed a bug that caused a failure of an assignment statement preceding a
+ builtin caused the next invocation of a special builtin to exit the shell.
+
+rrrr. Fixed several problems with IFS when it appears in the temporary environment

+ n closed if executed with a builtin command.
+
+ccccc. Fixed a bug that caused incorrect completion quoting when completing a
+ word containing a globbing character with `show-all-if-ambiguous' set.
+
+ddddd. Fixed a bug that caused printf's %q format specifier not to quote a
+ tilde even if it appeared in a location where it would be subject to
+ tilde expansion.
+
+2. Changes to Readline
+
+a. Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode
+ commands to work on the entire line.
+
+b. Fixed a bug that caused redisplay problems with prompts longer than 128
+ characters and history searches.
+
+c. Fixed a bug that caused readline to try and run code to modify its idea
+ of the screen size in a signal handler context upon receiving a SIGWINCH.
+
+d. Fixed a bug that caused the `meta' key to be enabled beyond the duration
+ of an individual call top readline().
+
+e. Added a workaround for a wcwidth bug in Mac OS X that caused readline's

+
+f. Fixed a bug that caused readline to `forget' part of a key sequence when
+ a multiple-key sequence caused it to break out of an incremental search.
+

+
+i. Fixed a bug that caused Readline's signal handlers to be installed beyond
+ the bounds of a single call to readline().
+
+j. Fixed a bug that caused the `.' command to not redo the most recent `R'
+ command in vi mode.
+
+k. Fixed a bug that caused ignoring case in completion matches to result in
+ readline using the wrong match.

+ multibyte characters correctly when using case-sensitive or case-mapping
+ comparisons.
+
+p. Fixed the input reading loop to call the input hook function only when there
+ is no terminal input available.
+
+q. Fixed a bug that caused binding a macro to a multi-character key sequence

+
+r. Fixed several redisplay errors with multibyte characters and prompts
+ containing invisible characters when using horizontal scrolling.
+
+s. Fixed a bug that caused redisplay errors when trying to overwrite
+ existing characters using multibyte characters.
+
+3. New Features in Bash
+
+a. The `helptopic' completion action now maps to all the help topics, not just
+ the shell builtins.
+
+b. The `help' builtin no longer does prefix substring matching, so `help read'
+ does not match `readonly'.
+
+c. The shell can be compiled to not display a message about processes that
+ terminate due to SIGTERM.
+
+d. Non-interactive shells now react to the setting of checkwinsize and set
+ LINES and COLUMNS after a foreground job exits.
+
+e. There is a new shell option, `globasciiranges', which, when set to on,
+ forces globbing range comparisons to use character ordering as if they
+ were run in the C locale.
+
+f. There is a new shell option, `direxpand', which makes filename completion
+ expand variables in directory names in the way bash-4.1 did.
+
+g. In Posix mode, the `command' builtin does not change whether or not a
+ builtin it shadows is treated as an assignment builtin.
+
+h. The `return' and `exit' builtins accept negative exit status arguments.
+
+i. The word completion code checks whether or not a filename containing a
+ shell variable expands to a directory name and appends `/' to the word
+ as appropriate. The same code expands shell variables in command names
+ when performing command completion.
+
+j. In Posix mode, it is now an error to attempt to define a shell function
+ with the same name as a Posix special builtin.
+
+k. When compiled for strict Posix conformance, history expansion is disabled
+ by default.
+
+l. The history expansion character (!) does not cause history expansion when
+ followed by the closing quote in a double-quoted string.
+
+m. `complete' and its siblings compgen/compopt now takes a new `-o noquote'
+ option to inhibit quoting of the completions.
+
+n. Setting HISTSIZE to a value less than zero causes the history list to be
+ unlimited (setting it 0 zero disables the history list).
+
+o. Setting HISTFILESIZE to a value less than zero causes the history file size
+ to be unlimited (setting it to 0 causes the history file to be truncated
+ to zero size).
+
+p. The `read' builtin now skips NUL bytes in the input.
+
+q. There is a new `bind -X' option to print all key sequences bound to Unix
+ commands.
+
+r. When in Posix mode, `read' is interruptible by a trapped signal. After
+ running the trap handler, read returns 128+signal and throws away any
+ partially-read input.
+
+s. The command completion code skips whitespace and assignment statements
+ before looking for the command name word to be completed.
+
+t. The build process has a new mechanism for constructing separate help files
+ that better reflects the current set of compilation options.
+
+u. The -nt and -ot options to test now work with files with nanosecond
+ timestamp resolution.
+
+v. The shell saves the command history in any shell for which history is
+ enabled and HISTFILE is set, not just interactive shells.
+
+w. The shell has `nameref' variables and new -n(/+n) options to declare and
+ unset to use them, and a `test -R' option to test for them.
+
+x. The shell now allows assigning, referencing, and unsetting elements of
+ indexed arrays using negative subscripts (a[-1]=2, echo ${a[-1]}) which
+ count back from the last element of the array.
+
+y. The {x}<word redirection feature now allows words like {array[ind]} and
+ can use variables with special meanings to the shell (e.g., BASH_XTRACEFD).
+
+z. There is a new CHILD_MAX special shell variable; its value controls the
+ number of exited child statues the shell remembers.
+
+aa. There is a new configuration option (--enable-direxpand-default) that
+ causes the `direxpand' shell option to be enabled by default.
+
+bb. Bash does not do anything special to ensure that the file descriptor
+ assigned to X in {x}<foo remains open after the block containing it
+ completes.
+
+cc. The `wait' builtin has a new `-n' option to wait for the next child to
+ change status.
+
+dd. The `printf' %(...)T format specifier now uses the current time if no
+ argument is supplied.
+
+ee. There is a new variable, BASH_COMPAT, that controls the current shell
+ compatibility level.
+
+ff. The `popd' builtin now treats additional arguments as errors.
+
+gg. The brace expansion code now treats a failed sequence expansion as a
+ simple string and will continue to expand brace terms in the remainder
+ of the word.
+
+4. New Features in Readline
+
+a. Readline is now more responsive to SIGHUP and other fatal signals when
+ reading input from the terminal or performing word completion but no
+ longer attempts to run any not-allowable functions from a signal handler
+ context.
+
+b. There are new bindable commands to search the history for the string of
+ characters between the beginning of the line and the point
+ (history-substring-search-forward, history-substring-search-backward)
+
+c. Readline allows quoted strings as the values of variables when setting
+ them with `set'. As a side effect, trailing spaces and tabs are ignored
+ when setting a string variable's value.
+
+d. The history library creates a backup of the history file when writing it
+ and restores the backup on a write error.
+
+e. New application-settable variable: rl_filename_stat_hook: a function called
+ with a filename before using it in a call to stat(2). Bash uses it to
+ expand shell variables so things like $HOME/Downloads have a slash
+ appended.
+
+f. New bindable function `print-last-kbd-macro', prints the most-recently-
+ defined keyboard macro in a reusable format.
+
+g. New user-settable variable `colored-stats', enables use of colored text
+ to denote file types when displaying possible completions (colored analog
+ of visible-stats).
+
+h. New user-settable variable `keyseq-timout', acts as an inter-character
+ timeout when reading input or incremental search strings.
+
+i. New application-callable function: rl_clear_history. Clears the history list
+ and frees all readline-associated private data.
+
+j. New user-settable variable, show-mode-in-prompt, adds a characters to the
+ beginning of the prompt indicating the current editing mode.
+
+k. New application-settable variable: rl_input_available_hook; function to be
+ called when readline detects there is data available on its input file
+ descriptor.
+
+l. Readline calls an application-set event hook (rl_signal_event_hook) after
+ it gets a signal while reading input (read returns -1/EINTR but readline
+ does not handle the signal immediately) to allow the application to handle
+ or otherwise note it. Not currently called for SIGHUP or SIGTERM.
+
+m. If the user-settable variable `history-size' is set to a value less than
+ 0, the history list size is unlimited.

+ resulting in stack corruption.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.2-rc2,
+and the previous version, bash-4.2-rc1.
+
+1. Changes to Bash
+
+a. Changes to bash_directory_completion_hook so that it's assigned to the
+ readline rl_directory_rewrite_hook variable, which modifies the directory
+ name passed to opendir without modifying the directory name the user
+ typed.
+
+b. Fixed bug in select builtin that caused it to not terminate correctly if
+ the read timed out due to $TMOUT.
+
+c. Fixed a problem that resulted in non-repeatable sequences of random
+ numbers when RANDOM=0.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.2-rc1,
+and the previous version, bash-4.2-beta.
+
+1. Changes to Bash
+
+a. Fixed a bug that caused some redirection errors to leak file descriptors.
+
+b. Fixed a bug that caused unary `+' and `-' arithmetic operators to have a
+ higher precedence than unary `!' and `~'.
+
+c. Fixed a bug that caused simple commands in a pipeline to affect the exit
+ status ($?) seen by subsequent pipeline commands.
+
+d. A number of cygwin-specific changes to avoid the use of text-mode files

+
+e. Fixed a bug that caused the read builtin to not return failure if an
+ attempt is made to assign to a readonly variable.
+
+f. Fixed a bug that caused some builtin usage messages to not be translated.
+
+g. Fixed a bug that caused the getopts builtin to not return failure if an
+ attempt is made to assign to a readonly variable. Now it returns 2.
+
+h. Fixed the cd and pwd builtins to return failure if PWD is readonly and
+ cannot be assigned to.
+
+i. Added code to check the return value of access(2) on Solaris systems,
+ since it returns success for executable tests (e.g., `test -x') when
+ run by root, even if the file permissions don't allow execution.
+
+2. Changes to Readline
+
+a. Fixed a bug that caused directory names in words to be completed to not
+ be dequoted correctly.
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.2-beta,
+and the previous version, bash-4.2-alpha.
+
+1. Changes to Bash
+
+a. Fixed a bug that caused the \W prompt string escape to not add a closing
+ NULL.
+
+b. Fixed a bug that caused partially-quoted words that were not subject to
+ word splitting to retained quoted NULLs.
+
+c. Added considerable efficiency speedups when pattern matching in multibyte
+ locales by skipping multibyte character functions where possible.
+
+d. Added considerable speedups to variable expansion when in multibyte locales.
+
+e. Fixed a bug that caused the expansion of $* when there are no positional
+ parameters to cause the shell to dump core when used in a pattern
+ matching context.
+
+f. Fixed a bug that caused variable expansions preceding regular builtins to
+ not change the shell environment during their execution.
+
+2. Changes to Readline
+
+a. Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
+ as if it were a negative argument.
+
+------------------------------------------------------------------------------
+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 and 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.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.1-rc,
+and the previous version, bash-4.1-beta.
+
+1. Changes to Bash
+
+a. Fixed a bug that caused printf to not return a partial value when it
+ encountered an error while converting an integer argument.
+
+b. Fixed a bug that caused setting one of the compatNN options to not
+ turn off the others.
+
+c. The (undocumented) --wordexp option is no longer included by default.
+
+d. Fixed a bug in conditional command execution that caused it to not
+ correctly ignore the exit status under certain circumstances.

+
+f. Fixed some problems with line number calculation and display when sourcing
+ a file in an interactive shell.
+

+
+h. Fixed a bug that caused an off-by-one error when calculating the directories
+ to display with the PROMPT_DIRTRIM option.
+
+2. Changes to Readline
+
+a. Fixed a bug that caused applications using the callback interface to not
+ react to SIGINT (or other signals) until another character arrived.
+

+
+d. Fixed a bug that caused the shell to read commands incorrectly if an
+ expansion error occurred under certain conditions in a user-specified
+ subshell.
+
+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.)
+
+f. Fixed a bug that caused the shell to attempt command substitution
+ completion within a single-quoted string.
+
+g. Fixed a bug that caused the shell to insert an extra single quote during
+ word completion.
+
+h. Fixed a bug that caused the shell to crash if invoked with the environment
+ variable EMACS having a null value.
+
+i. Fixed a bug that caused bash to incorrectly report the presence of new
+ mail in a `maildir' environment.
+
+j. Fixed a bug that caused the shell to not recognize a here-document ending
+ delimiter inside a command substitution.
+
+k. Fixed a bug that caused the shell to crash when a a dynamic array variable
+ was assigned a scalar value.
+
+2. Changes to Readline
+
+3. New Features in Bash
+
+a. The mapfile/readarray builtin no longer stores the commands it invokes via
+ callbacks in the history list.
+
+b. There is a new `compat40' shopt option.

+c. The < and > operators to [[ do string comparisons using the current locale
+ only if the compatibility level is greater than 40 (set to 41 by default).
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.1-alpha,
+and the previous version, bash-4.0-release.
+
+1. Changes to Bash
+
+a. Fixed bugs in the parser involving new parsing of the commands contained
+ in command substitution when the substitution is read.
+
+b. Fixed a bug that caused the shell to dump core when performing programmable
+ completion using a shell function.
+
+c. Fixed a bug in `mapfile' that caused it to invoke callbacks at the wrong
+ time.
+
+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
+ the `fc' builtin.
+
+r. Fixed a bug that caused some terminating signals to not exit the shell
+ quickly enough, forcing the kernel to send the signal (e.g., SIGSEGV)
+ 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.
+
+bb. Fixed a bug that caused brace expansion to take place too soon in some
+ compound array assignments.
+
+cc. Fixed a bug that caused programmable completion functions' changes to
+ READLINE_POINT to not be reflected back to readline.
+
+dd. Fixed a bug that caused the shell to dump core if a trap was executed
+ during a shell assignment statement.
+
+ee. Fixed an off-by-one error when computing the number of positional
+ parameters for the ${@:0:n} expansion.
+
+ff. Fixed a problem with setting COMP_CWORD for programmable completion
+ functions that could leave it set to -1.
+
+gg. Fixed a bug that caused the ERR trap to be triggered in some cases where
+ `set -e' would not have caused the shell to exit.
+
+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.
+
+u. The read builtin has a new `-N nchars' option, which reads exactly NCHARS
+ 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.

+ waiting for 4096 jobs.
+
+cc. Fixed a bug that caused bash to lose the status of a background job under
+ certain circumstances.
+
+dd. Fixed a bug that caused bash to not look in the temporary environment
+ when performing variable lookup under certain circumstances.
+
+ee. Fixed a bug that caused bash to close file descriptors greater than 10
+ when they were used in redirections.
+
+ff. Fixed a problem that caused the shell to attempt to read from the standard
+ input when called as `bash -i script'.
+
+gg. Fixed a memory leak and variable initialization problems when the -v option
+ was supplied to `printf' that could cause incorrect results.
+
+hh. Fixed a bug that caused the `read' builtin to count bytes when the -n option

+oo. Fixed a bug in pathname expansion that caused it to interpret backslashes
+ in the pathname as quoting characters.
+
+pp. Fixed a bug in the replacement getcwd() implementation that could cause
+ memory to be overwritten.
+
+qq. When in Posix mode, the `ulimit' builtin now uses a block size of 512 for
+ the `-c' and `-f' options.
+
+rr. Brace expansion now allows process substitutions to pass through unchanged.
+
+ss. Fixed a problem in the command name completion code to avoid quoting
+ escaped special characters twice when the command name begins with a tilde.
+
+tt. Fixed a problem in the printf builtin that resulted in single-byte
+ output for the "'" escape, even when using multibyte characters.
+
+uu. Fixed a bug that caused the failure exit status to be lost when redirections

+
+vv. Fixed a bug that caused the internal random number generator to not be
+ re-seeded correctly when creating a subshell.
+
+ww. Fixed a bug that could cause the bash replacement getcwd to overwrite
+ memory.
+
+xx. Fixed a bug that caused the shell to not receive SIGINT if it was sent
+ while the shell was waiting for a command substitution to terminate, and
+ make sure the exit status is correct when it does.
+
+yy. Fixed a bug that resulted in the second and subsequent children spawned
+ by a shell begun to run a command substitution being placed into the
+ wrong process group.
+
+zz. Fixed a bug that caused the results of successful tilde expansion to be
+ subject to pathname expansion and word splitting.
+
+aaa. Fixed a bug that could cause the shell to hang if it encountered an
+ error that caused it to jump back to the top processing loop during a
+ command substitution or `eval' command.
+
+bbb. Fixed a bug that caused the `read' builtin to use the tty's attributes
+ instead of those of the file descriptor passed with the -u option when
+ processing the -n and -d options.
+
+ccc. Fixed a bug that caused incorrect expansion of ${array[@]:foo} if the
+ first character of $IFS was not whitespace.
+
+ddd. Fixed a bug that occurred when scanning for the ending delimiter of a
+ ${parameter/pat/sub} expansion.
+
+eee. Fixed a bug that caused the shell to inappropriately expand command
+ substitutions in words when expanding directory names for completion.
+
+fff. Fixed a bug that caused the `fc' builtin to look too far back in the
+ history list under certain circumstances.
+
+ggg. Fixed a bug that caused a shell running in Posix mode to search $PWD for
+ a file specified as an argument to source/. when the file was not found
+ in $PATH.
+
+hhh. Fixed a bug that caused the shell to modify the case of a command word
+ found via command completion when the shell was performing case-
+ insensitive completion.
+
+iii. Fixed a bug that caused the shell to search $PATH for an argument to
+ source/. even when it contained a `/'.
+
+jjj. Fixed a bug that caused brace expansion to misorder expansions when the
+ locale did not have a collating order like aAbBcC...zZ.
+
+kkk. Fixed a bug that did not allow `set +o history' to have any effect when
+ run in a startup file or from a sourced file.
+
+lll. Fixed a bug with the precedence of the ?: conditional arithmetic operator.
+
+mmm. Fixed a bug that caused side effects of temporary variable assignments
+ to persist in the shell environment.
+
+nnn. Fixed a bug that caused the terminal to be left in non-canonical mode

+ invalid names if such names appeared in the initial environment.
+
+rrr. Fixed a bug with quote removal in strings where the final character is a
+ backslash.
+
+sss. Fixed a bug that caused the effects of special variables to persist even
+ when the variables were unset as part of the shell reinitializing itself
+ to execute a shell script.
+
+ttt. Fixed a bug that caused the history to not be saved after `history -c' or
+ `history -d' was executed until a sufficient number of commands had been
+ saved to the history.
+
+uuu. Bash now parses command substitutions according to Posix rules: parsing
+ the command contained in $() to find the closing delimiter.
+
+vvv. Fixed a bug that caused traps on SIGCHLD set in a SIGCHLD handler to
+ not persist.
+
+www. Fixed a bug that didn't allow SIGCHLD to interrupt the `wait' builtin
+ as Posix specifies.
+
+xxx. Invalid numeric arguments to shell builtins no longer cause the shell to
+ short-circuit any executing compound command.
+
+yyy. Fixed a bug that caused the exit status to be lost when `break' was
+ used to short-circuit a loop's execution.
+
+zzz. Fixed a bug that caused stray ^? characters to be left in expansions of
+ "${array[*]}".
+
+aaaa. Bash now prints better error messages for here documents terminated by
+ EOF and for identifying the incorrect token in an invalid arithmetic
+ expression.
+
+bbbb. Fixed a bug in the variable length word expansion that caused it to
+ incorrectly calculate the number of multibyte characters.
+
+cccc. Fixed a race condition that could result in the top-level shell setting

+ group was changed by a child of a child of the shell.
+
+dddd. Fixed a bug that caused here documents belonging to commands within a
+ compound command to be displayed in a syntactially-incorrect form, which
+ prevented them from being re-read as input.
+
+eeee. The shell displays more warnings about failures to set the locale.
+
+ffff. Fixed a bug that caused the body of a here-document to not be saved to
+ the history list.
+
+gggg. Fixed a bug that caused configure to incorrectly conclude that FreeBSD
+ had /dev/fd available, resulting in problems with process substitution.
+
+2. Changes to Readline
+
+a. Fixed a number of redisplay errors in environments supporting multibyte
+ characters.
+
+b. Fixed bugs in vi command mode that caused motion commands to inappropriately
+ set the mark.
+
+c. When using the arrow keys in vi insertion mode, readline allows movement
+ beyond the current end of the line (unlike command mode).
+
+d. Fixed bugs that caused readline to loop when the terminal has been taken
+ away and reads return -1/EIO.
+
+e. Fixed bugs in redisplay occurring when displaying prompts containing
+ invisible characters.
+
+f. Fixed a bug that caused the completion append character to not be reset to
+ the default after an application-specified completion function changed it.
+
+g. Fixed a problem that caused incorrect positioning of the cursor while in
+ emacs editing mode when moving forward at the end of a line while using
+ a locale supporting multibyte characters.
+
+h. Fixed an off-by-one error that caused readline to drop every 511th
+ character of buffered input.
+
+i. Fixed a bug that resulted in SIGTERM not being caught or cleaned up.
+
+j. Fixed redisplay bugs caused by multiline prompts with invisible characters
+ or no characters following the final newline.
+
+k. Fixed redisplay bug caused by prompts consisting solely of invisible
+ characters.
+
+l. Fixed a bug in the code that buffers characters received very quickly in
+ succession which caused characters to be dropped.
+
+m. Fixed a bug that caused readline to reference uninitialized data structures
+ if it received a SIGWINCH before completing initialzation.
+
+n. Fixed a bug that caused the vi-mode `last command' to be set incorrectly
+ and therefore unrepeatable.
+
+o. Fixed a bug that caused readline to disable echoing when it was being used
+ with an output file descriptor that was not a terminal.
+
+p. Readline now blocks SIGINT while manipulating internal data structures
+ during redisplay.
+
+q. Fixed a bug in redisplay that caused readline to segfault when pasting a
+ very long line (over 130,000 characters).
+
+r. Fixed bugs in redisplay when using prompts with no visible printing
+ characters.
+
+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.

+and the previous version, bash-3.2-beta.
+
+1. Changes to Bash
+
+a. Fixed a bug that caused the temporary environment passed to a command to
+ affect the shell's environment under certain circumstances.
+
+b. Fixed a bug in the printf builtin that caused the %q format specifier to
+ ignore empty string arguments.
+
+c. Improved multibyte character environment detection at configuration time.
+
+d. Fixed a bug in the read builtin that left spurious escape characters in the
+ input after processing backslashes when assigning to an array variable.
+
+2. Changes to Readline
+
+a. Fixed a redisplay bug that occurred in multibyte-capable locales when the
+ prompt was one character longer than the screen width.
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.2-beta,
+and the previous version, bash-3.2-alpha.
+
+1. Changes to Bash
+
+a. Changed the lexical analyzer to treat locale-specific blank characters as
+ white space.
+
+b. Fixed a bug in command printing to avoid confusion between redirections and
+ process substitution.
+
+c. Fixed problems with cross-compiling originating from inherited environment
+ variables.
+
+d. Added write error reporting to printf builtin.
+
+e. Fixed a bug in the variable expansion code that could cause a core dump in
+ a multi-byte locale.
+

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

+
+d. Fixed a small memory leak in the programmable completion code.
+
+2. Changes to Readline
+
+a. Fixed a redisplay bug caused by moving the cursor vertically to a line
+ with invisible characters in the prompt in a multibyte locale.

+3. New Features in Bash
+
+a. If compiled for strict POSIX conformance, LINES and COLUMNS may now
+ override the true terminal size.
+
+4. New Features in Readline
+
+a. A new external application-controllable variable that allows the LINES
+ and COLUMNS environment variables to set the window size regardless of
+ what the kernel returns.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.1-rc1,
+and the previous version, bash-3.1-beta1.
+
+1. Changes to Bash
+
+a. Fixed a bug that could cause core dumps due to accessing the current
+ pipeline while in the middle of modifying it.
+
+b. Fixed a bug that caused pathnames with backslashes still quoting characters
+ to be passed to opendir().
+
+c. Command word completion now obeys the setting of completion-ignore-case.
+
+d. Fixed a problem with redirection that caused file descriptors greater than
+ 2 to be inappropriately marked as close-on-exec.
+
+e. In Posix mode, after `wait' is called to wait for a particular process
+ explicitly, that process is removed from the list of processes known to
+ the shell, and subsequent attempts to wait for it return errors.
+
+f. Fixed a bug that caused extended pattern matching to incorrectly scan
+ backslash-escaped pattern characters.
+
+g. Fixed a synchronization problem that could cause core dumps when handling
+ a SIGWINCH.
+
+h. Fixed a bug that caused an unmatched backquote to be accepted without an
+ error when processing here documents.
+
+i. Fixed a small memory leak in the `cd' builtin.
+
+j. Fix for MacOS X so it gets the values for the HOSTTYPE, MACHTYPE, and
+ OSTYPE variables at build time, to support universal binaries.
+
+k. Fixed a bug that could cause an exit trap to return the exit status of
+ the trap command rather than the status as it was before the trap was
+ run as the shell's exit status.
+
+2. New Features in Bash
+
+3. Changes to Readline
+
+a. Fixed a bug that caused reversing the incremental search direction to
+ not work correctly.
+
+b. Fixed the vi-mode `U' command to only undo up to the first time insert mode
+ was entered, as Posix specifies.
+
+c. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong
+ place.
+
+4. New Features in Readline
+
+a. New application-callable auxiliary function, rl_variable_value, returns
+ a string corresponding to a readline variable's value.
+
+b. When parsing inputrc files and variable binding commands, the parser
+ strips trailing whitespace from values assigned to boolean variables
+ before checking them.
+
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.1-beta1,
+and the previous version, bash-3.1-alpha1.
+
+1. Changes to Bash
+
+a. Added some system-specific signal names.
+
+b. Fixed a typo in the ulimit builtin to make `x' the right option to
+ maniuplate the limit on file locks.
+
+c. Fixed a problem with using += to append to index 0 of an array variable
+ 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
+ directory as `.', even when displaying $PWD.
+
+n. Fixed a problem with the `read' builtin when reading a script from standard
+ input and reading data from the same file.
+
+o. Fixed a problem with the `type' and `command' builtins that caused absolute
+ pathnames to be displayed incorrectly.
+
+p. Some changes to the `bg' builtin for POSIX conformance.
+
+q. The `fc' builtin now removes the `fc' command that caused it to invoke an
+ editor on specified history entries from the history entirely, rather than
+ simply ignoring it.
+
+r. 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.
+
+1. Changes to Bash
+
+a. Fixed a bug that caused bash to crash if referencing an unset local array.
+
+b. Fixed a problem that caused tilde expansion to not be performed before
+ attempting globbing word completion.
+
+c. Fixed an incompatibility so that a first argument to trap that's a valid
+ signal number will be trated as a signal rather than a command to execute.
+
+d. Fixed ${#word} expansion to correctly compute the length of a string
+ containing multibyte characters.
+
+e. Fixed a bug that caused bash to not pass the correct flags for signal
+ disposition to child processes.
+
+f. Fixed a bug that caused `fc -l' to list one too many history entries.
+
+g. Some fixes to `fc' for POSIX conformance.
+
+h. Some fixes to job status display for POSIX conformance.
+
+i. Fixed a bug that caused `command -v' to display output if a command was not
+ found -- it should be silent.
+
+j. In POSIX mode, `type' and `command -[vV]' do not report non-executable
+ files, even if the shell will attempt to execute them.
+
+k. Fixed a bug that caused the `==' operator to the [[ command to not attempt
+ extended pattern matching.
+
+l. Fixed the brace expansion code to handle characters whose value exceeds 128.
+
+m. Fixed `printf' to handle strings with a leading `\0' whose length is
+ non-zero.
+
+n. Fixed a couple of problems with brace expansion where `${' was handled
+ incorrectly.
+
+o. Fixed off-by-one error when calculating the upper bound of `offset' when
+ processing the ${array[@]:offset:length} expansion.
+
+p. System-specific configuration changes for: FreeBSD 5.x, Interix, MacOS X
+ 10.4, Linux 2.4+ kernels, Linux 3.x kernels, Dragonfly BSD, QNX 6.x,
+ Cygwin
+
+q. Fixed a bug that caused the shell to ignore the status of the rightmost
+ command in a pipeline when the `pipefail' option was enabled.
+
+r. Fixed a completion bug that caused core dumps when expanding a directory
+ name.
+
+s. Fixed a bug that prevented `hash -d' from removing commands from the hash
+ table.
+
+t. Fixed word splitting to avoid really bad quadratic performance when
+ expanding long lists.
+
+u. Fixed a bug that caused negative offsets in substring expansion to use the
+ wrong values.
+
+v. Fixed a bug in printf that caused it to not return failure on write errors.
+
+w. Fixed a bug that caused commands in subshells to not be properly timed.
+
+x. The shell parser no longer attempts to parse a compound assignment specially
+ unless in a position where an assignment statement is acceptable or parsing
+ arguments to a builtin that accepts assignment statements.
+
+y. Fixed a problem that caused a `case' statement to be added to the history
+ incorrectly as a single command if the `case word' was on one line and the
+ `in' on another.
+
+z. Fixed a problem that caused internal shell quoting characters to be
+ incorrectly quoted with backslashes under some circumstances.
+
+aa. The shell now performs correct word splitting when IFS contains multibyte
+ characters.
+
+bb. The mail checking code now resets the cached file information if the size
+ drops to 0, even if the times don't change.
+
+cc. A completed command name that is found in $PATH as well as the name of a
+ directory in the current directory no longer has a slash appended in certain
+ circumstances: a single instance found in $PATH when `.' is not in $PATH,
+ and multiple instances found in $PATH, even when `.' is in $PATH.
+
+dd. Incorporated tilde expansion into the word expansion code rather than as a
+ separately-called function, fixing some cases where it was performed
+ inappropriately (e.g., after the second `=' in an assignment statement or
+ in a double-quoted parameter expansion).
+
+ee. Fixed several bugs encountered when parsing compound assignment statements,
+ so that compound assignments appearing as arguments to builtins are no
+ longer double-expanded.
+
+ff. Fixed a bug in the command execution code that caused asynchronous commands
+ containing command substitutions to not put the terminal in the wrong
+ process group.
+
+gg. Bash now handles the case where the WCONTINUED flag causes waitpid() to
+ return -1/EINVAL at runtime as well as configuration time.
+
+hh. Fixed parser to generate an error when the pipeline `argument' to `!' or
+ `time' is NULL.
+
+ii. The shell now takes a little more care when manipulating file descriptors
+ greater than 9 with the `exec' builtin.
+
+jj. Fixed a bug that caused variable assignments preceding the `command' builtin
+ preceding a special builtin to be preserved after the command completed in
+ POSIX mode.
+
+kk. Fixed a bug that allowed variables beginning with a digit to be created.
+
+ll. Fixed a bug that caused a \<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
+ no `/' to be appended to a directory name.
+
+j. Fixed forward-word and backward-word to work when words contained
+ multibyte characters.
+
+k. Fixed a bug in finding the delimiter of a `?' substring when performing
+ history expansion in a locale that supports multibyte characters.
+
+l. Fixed a memory leak caused by not freeing the timestamp in a history entry.
+
+m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting
+ of the `convert-meta' variable.
+
+n. Fixed saving and restoring primary prompt when prompting for incremental
+ and non-incremental searches; search prompts now display multibyte
+ characters correctly.
+
+o. Fixed a bug that caused keys originally bound to self-insert but shadowed
+ by a multi-character key sequence to not be inserted.
+
+p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
+ dereferenced if NULL (matching the documentation).
+
+q. Extensive changes to readline to add enough state so that commands
+ requiring additional characters (searches, multi-key sequences, numeric
+ arguments, commands requiring an additional specifier character like
+ vi-mode change-char, etc.) work without synchronously waiting for
+ additional input.
+
+r. Lots of changes so readline builds and runs on MinGW.
+
+s. Readline no longer tries to modify the terminal settings when running in
+ callback mode.
+
+t. The Readline display code no longer sets the location of the last invisible
+ character in the prompt if the \[\] sequence is empty.
+
+3. New Features in Bash
+
+a. Bash now understands LC_TIME as a special variable so that time display
+ tracks the current locale.
+
+b. BASH_ARGC, BASH_ARGV, BASH_SOURCE, and BASH_LINENO are no longer created
+ as `invisible' variables and may not be unset.
+
+c. In POSIX mode, if `xpg_echo' option is enabled, the `echo' builtin doesn't
+ try to interpret any options at all, as POSIX requires.
+
+d. The `bg' builtin now accepts multiple arguments, as POSIX seems to specify.
+
+e. Fixed vi-mode word completion and glob expansion to perform tilde
+ expansion.
+
+f. The `**' mathematic exponentiation operator is now right-associative.
+
+g. The `ulimit' builtin has new options: -i (max number of pending signals),
+ -q (max size of POSIX message queues), and -x (max number of file locks).
+
+h. A bare `%' once again expands to the current job when used as a job
+ specifier.
+
+i. The `+=' assignment operator (append to the value of a string or array) is
+ now supported for assignment statements and arguments to builtin commands
+ that accept assignment statements.
+
+j. BASH_COMMAND now preserves its value when a DEBUG trap is executed.
+
+k. The `gnu_errfmt' option is enabled automatically if the shell is running
+ in an emacs terminal window.
+
+l. New configuration option: --single-help-strings. Causes long help text
+ to be written as a single string; intended to ease translation.
+
+m. The COMP_WORDBREAKS variable now causes the list of word break characters
+ to be emptied when the variable is unset.
+
+n. An unquoted expansion of $* when $IFS is empty now causes the positional
+ parameters to be concatenated if the expansion doesn't undergo word
+ splitting.
+
+o. Bash now inherits $_ from the environment if it appears there at startup.
+
+p. New shell option: nocasematch. If non-zero, shell pattern matching ignores
+ case when used by `case' and `[[' commands.
+
+q. The `printf' builtin takes a new option: -v var. That causes the output
+ to be placed into var instead of on stdout.
+
+r. By default, the shell no longer reports processes dying from SIGPIPE.
+
+s. Bash now sets the extern variable `environ' to the export environment it
+ creates, so C library functions that call getenv() (and can't use the
+ shell-provided replacement) get current values of environment variables.
+
+4. New Features in Readline
+
+a. The key sequence sent by the keypad `delete' key is now automatically
+ bound to delete-char.
+
+b. A negative argument to menu-complete now cycles backward through the
+ completion list.
+
+c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
+ readline will bind the terminal special characters to their readline
+ equivalents when it's called (on by default).
+
+d. New bindable command: vi-rubout. Saves deleted text for possible
+ reinsertion, as with any vi-mode `text modification' command; `X' is bound
+ to this in vi command mode.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-release,
+and the previous version, bash-3.0-rc1.
+
+1. Changes to Bash
+
+a. Fixed a boundary overrun that could cause segmentation faults when the
+ completion code hands an incomplete construct to the word expansion
+ functions.
+
+b. Changed posix mode behavior so that an error in a variable assignment
+ preceding a special builtin causes a non-interactive shell to exit.
+
+c. Change the directory expansion portion of the completion code to not
+ expand embedded command substitutions if the directory name appears in
+ the file system.
+
+d. Fixed a problem that caused `bash -r' to turn on restrictions before
+ reading the startup files.
+
+e. Fixed a problem with the default operation of the `umask' builtin.
+
+2. Changes to Readline
+
+a. Fixed a problem with readline saving the contents of the current line
+ before beginning a non-interactive search.
+
+b. Fixed a problem with EOF detection when using rl_event_hook.
+
+c. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric
+ arguments.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-rc1,
+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
+ an array using $array, element 0 was unset, and `set -u' was enabled.
+
+b. System-specific changes for: SCO Unix 3.2, Tandem.
+
+c. Fixed a bug that caused inappropriate word splitting when a variable was
+ expanded within a double-quoted string that also included $@.
+
+d. Fixed a bug that caused `pwd' to not display anything in physical mode
+ when the file system had changed underneath the shell.
+
+e. Fixed a bug in the pre- and post- increment and decrement parsing in the
+ expression evaluator that caused errors when the operands and corresponding
+ operators were separated by whitespace.
+
+f. Fixed a bug that caused `history -p' to add an entry to the history list,
+ counter to the documentation. (Keeps the history expansions invoked by
+ emacs-mode command line editing from doing that as well.)
+
+g. Fixed a bug that could cause a core dump if `cd' is asked to print out a
+ pathname longer than PATH_MAX characters.
+
+h. Fixed a bug that caused jobs to be put into the wrong process group under
+ some circumstances after enabling job control with `set -m'.
+
+i. `unalias' now returns failure if no alias name arguments are supplied.
+
+j. Documented the characters not allowed to appear in an alias name.
+
+k. $* is no longer expanded as if in double quotes when it appears in the
+ body of a here document, as the SUS seems to require.
+
+l. The `bashbug' script now uses a directory in $TMPDIR for exclusive
+ access rather than trying to guess how the underlying OS provides for
+ secure temporary file creation.
+
+m. Fixed a few problems with `cd' and `pwd' when asked to operate on pathnames
+ longer than PATH_MAX characters.
+
+n. Fixed a memory leak caused when creating multiple local array variables
+ with identical names.
+
+o. Fixed a problem with calls to getcwd() so that bash now operates better
+ when the full pathname to the current directory is longer than PATH_MAX
+ bytes.
+
+p. The `trap' builtin now reports an error if a single non-signal argument
+ is specified.
+
+q. Fixed a bug that caused `umask' to not work correctly when presented
+ with a mask of all 0s.
+
+r. When `getopts' reaches the end of options, OPTARG is unset, as POSIX
+ appears to specify.
+
+s. Interactive mode now depends on whether or not stdin and stderr are
+ connected to a tty; formerly it was stdin and stdout. POSIX requires
+ this.
+
+t. Fixed vi-mode completion to work more as POSIX specifies (e.g., doing the
+ right kind of filename generation).
+
+2. Changes to Readline
+
+a. Fixed a problem that could cause readline to refer to freed memory when
+ moving between history lines while doing searches.
+
+b. Improvements to the code that expands and displays prompt strings
+ containing multibyte characters.
+
+c. Fixed a problem with vi-mode not correctly remembering the numeric argument
+ to the last `c'hange command for later use with `.'.
+

+ to not be remembered across different command lines.
+
+f. Fixed problems with changing characters and changing case at the end of
+ the line.
+
+3. New Features in Bash
+
+a. The `jobs', `kill', and `wait' builtins now accept job control notation
+ even if job control is not enabled.
+
+b. The historical behavior of `trap' that allows a missing `action' argument
+ to cause each specified signal's handling to be reset to its default is
+ now only supported when `trap' is given a single non-option argument.
+
+4. New Features in Readline
+
+a. When listing completions, directories have a `/' appended if the
+ `mark-directories' option has been enabled.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-beta1,
+and the previous version, bash-3.0-alpha.
+
+1. Changes to Bash
+
+a. Fixes to build correctly when arrays are not compiled into the shell.
+
+b. Fixed command substitution to run any exit trap defined in the command
+ substitution before returning; the exit trap is not inherited from the
+ calling shell.
+
+c. 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.
+
+d. Fixed processing of octal and hex constants in printf builtin for POSIX.2
+ compliance.
+
+e. Fixed a couple of core dumps in the pattern removal code.
+
+f. Fixes to the array subrange extraction code to deal better with sparse
+ arrays.
+
+g. Parser errors and other errors that result in the shell exiting now cause
+ the exit trap to be run.
+
+h. Change the command substitution completion functions to not append any
+ closing quote, because it would be inserted a closing "`" or ")".
+
+i. Fix history initialization so assignments to $histchars made in startup
+ files are honored.
+
+j. If an exit trap does not contain a call to `exit', the shell now uses
+ the exit status of the last command executed before the trap as the exit
+ status of the shell.
+
+k. The parser now prompts with $PS2 if it reads a newline while parsing a
+ compound array assignment statement.
+
+l. When performing a compound array assignment, the parser doesn't treat
+ words of the form [index]=value as assignments if they're the result of
+ expansions.
+
+m. Fixed a bug that caused `return' executed in a trap command to make the
+ shell think it was still running the trap.
+
+n. Fixed the value of errno set by the pathname canonicalization functions.
+
+o. Changed the grammar so that `time' alone on a line times a null command
+ rather than being a syntax error.
+
+p. The pattern substitution code no longer performs quote removal on the
+ pattern before trying to match it, as the pattern removal functions do.
+
+q. Fixed a bug that could cause core dumps when checking whether a quoted
+ command name was being completed.
+
+r. Fixes to the pattern removal and pattern replacement expansions to deal
+ with multibyte characters better (and faster).
+
+s. Fix to the substring expansion (${param:off[:len]}) to deal with (possibly
+ multibyte) characters instead of raw bytes.
+
+t. Fixed a bug that caused some key bindings set in an inputrc to be ignored
+ at shell startup.
+
+u. Fixed a bug that caused unsetting a local variable within a function to
+ not work correctly.
+
+v. Fixed a bug that caused invalid variables to be created when using
+ `read -a'.
+
+w. Fixed a bug that caused "$@" to expand incorrectly when used as the right
+ hand side of a parameter expansion such as ${word:="$@"} if the first
+ character of $IFS was not a space.
+
+x. 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().
+
+qq. Fixed a bug that caused expansions like #{a[2]:=value} to create the
+ appropriate array element instead of a variable named `a[2]'.
+
+rr. Fixed a bug in the handling of a `?(...)' pattern immediately following
+ a `*' when extglob is enabled.
+
+ss. Fixed a bug that caused a `return' invoked in an exit trap when exit is
+ invoked in a function to misbehave.
+
+tt. Fixed a bug that caused CTLESC and CTLNUL characters to not be escaped
+ by the internal shell string quoting functions.
+
+uu. Fixed a bug that caused quoted null characters in an expanded word list
+ to be inappropriately assigned to an array variable when using `read -a'.
+
+vv. Fixed a bug that caused redirections accompanying a null command to persist
+ in the current shell.
+
+ww. Fixed a bug that caused the prompt to be printed when the shell was
+ expanding a multiline alias.
+
+xx. Fixed a bug that resulted in core dumps when the completion for a command
+ changed the compspec.
+
+yy. Fixed a bug that caused evaluation of programmable completions to print
+ notifications of completed jobs.
+
+zz. Bash now disables line editing when $EMACS == `t' and $TERM == `dumb'
+ (which is what emacs shell windows do).
+
+aaa. In posix mode, `kill -l' causes signal names to be displayed without
+ a leading `SIG'.
+
+bbb. Clear error flag on standard output so it doesn't persist across multiple
+ builtin commands.
+
+ccc. In posix mode, `alias' displays alias values without the leading `alias',
+ so the output cannot be used as subsequent input.
+
+ddd. In posix mode, the `trap' builtin doesn't check whether or not its
+ first argument is a signal specification and revert the signal handling
+ to its original disposition if it is.
+
+eee. Fixed several bugs in the handling of "$*" and "${array[*]}" by the
+ pattern substitution and removal expansions.
+
+fff. Fixed several problems with the handling of ${array[@]}, ${array[*]},
+ $@, and $* by the indirect variable expansion code.
+
+ggg. Fixed a bug that did not allow `time' to be aliased.
+
+hhh. Improved the mail checking code so it won't check (and possibly cause an
+ NFS file system mount) until MAILPATH or MAIL is given a value -- there
+ is no default if DEFAULT_MAIL_DIRECTORY is not defined at compile time.
+ (It is computed by configure, but can be #undef'd in config-bot.h.)
+
+iii. If the `chkwinsize' option is enabled, the shell checks for window size
+ changes if a child process exits due to a signal.
+
+jjj. Removed the attempts to avoid adding a slash at the end of a completed
+ executable name if there was a directory with the same name in the
+ current directory.
+
+kkk. Fixed PATH lookup code so it treats the permission bits separately for
+ owner, group, and other, rather than checking them all.
+
+lll. Fixed the locale code to reset the parser's idea of the character class
+ <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()
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-release,
+and the previous version, bash-2.05b-beta2.
+
+1. Changes to Bash
+
+a. Fixed an off-by-one error in the function that translates job
+ specifications.
+
+b. Note that we're running under Emacs and disable line editing if
+ $EMACS == `t'.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-beta2,
+and the previous version, bash-2.05b-beta1.
+
+1. Changes to Bash
+
+a. Fixed the /= and %= arithmetic operators to catch division by zero.
+
+b. Added putenv, setenv, unsetenv to getenv replacement for completeness.
+
+c. Fixed a bug that could cause the -O expand_aliases invocation option
+ to not take effect.
+
+d. Fixed a problem with process substitution that resulted in incorrect
+ behavior when the number of process substitutions in an individual
+ command approached 64.
+
+2. Changes to Readline
+
+a. Fixed a problem with backward-char-search when on a system with support
+ for multibyte characters when running in a locale without any multibyte
+ characters.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-beta1,
+and the previous version, bash-2.05b-alpha1.
+
+1. Changes to Bash
+
+a. Fixed a problem when parsing a POSIX.2 character class name while
+ evaluating a bracket expression containing multibyte characters.
+
+b. Changed the help text for `bind' to make it clear that any command
+ that may be placed in ~/.inputrc is a valid argument to `bind'.
+
+c. Added `help' builtin entries for `((', `[[', and arithmetic for.
+
+d. malloc updated again:
+ o slightly better overflow and underflow detection by putting the
+ chunk size at the beginning and end of the chunk and making
+ sure they match in free/realloc
+ o partial page allocated to make things page-aligned no longer
+ completely wasted
+ o block coalescing now enabled by default
+ o splitting and coalescing enabled for 32-byte chunks, the most
+ common size requested
+ o fixed a problem that resulted in spurious underflow messages and
+ aborts
+ o bin sizes are precomputed and stored in an array rather than
+ being computed at run time
+ o malloc will return memory blocks back to the system if the block
+ being freed is at the top of the heap and of sufficient size to
+ make it worthwhile
+ o malloc/free/realloc now inline memset instead of calling the
+ libc function; uses Duff's device for good performance
+
+e. Check for getservent(); make the service name completion code dependent
+ on its presence.
+
+f. Changed the readline callback that executes a command bound to a key
+ sequence to not save the executed command on the history list and to
+ save and restore the parsing state.
+
+g. Changes to lib/sh/snprintf.c: fixed some bugs in the `g' and `G'
+ floating point format display; implemented the "'" flag character
+ that turns on thousands' grouping; fixed behavior on systems where
+ MB_CUR_MAX does not evaluate to a constant.
+
+h. The `unset' builtin no longer returns a failure status when asked to
+ unset a previously-unset variable or function.
+
+i. Changes to the build system to make it easier to cross-compile bash
+ for different systems.
+
+j. Added `,' to the characters that are backslash-escaped during filename
+ completion, to avoid problems with complete-into-braces and RCS filenames
+ containing commas.
+
+k. Some changes to the multibyte character support code to avoid many calls
+ to strlen().
+
+l. Bash now correctly honors setting LANG to some value when LC_ALL does not
+ already have a value.
+
+m. Fixed a bug that could cause SIGSEGV when processing nested traps with
+ trap handlers.
+
+n. The `source/.' builtin now restores the positional parameters when it
+ returns unless they were changed using the `set' builtin during the file's
+ execution.
+
+o. Fixed a bug that caused a syntax error when a command was terminated by
+ EOF.
+
+2. New Features in Bash
+
+a. There is now support for placing the long help text into separate files
+ installed into ${datadir}/bash. Not enabled by default; can be turned
+ on with `--enable-separate-helpfiles' option to configure.
+
+b. All builtins that take operands accept a `--' pseudo-option, except
+ `echo'.
+
+c. The `echo' builtin now accepts \0xxx (zero to three octal digits following
+ the `0') in addition to \xxx (one to three octal digits) for SUSv3/XPG6/
+ POSIX.1-2001 compliance.
+
+3. Changes to Readline
+
+a. Fixed a small problem in _rl_insert_char with multibyte characters.
+
+b. Fixes from IBM for line wrapping problems when using multibyte characters.
+
+c. Fixed a problem which caused the display to be messed up when the last
+ line of a multi-line prompt (possibly containing invisible characters)
+ was longer than the screen width.
+
+d. Fixed a problem with the vi-mode `r' command that ocurred on systems with
+ support for multibyte characters when running in a locale without any
+ multibyte characters.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-alpha1,
+and the previous version, bash-2.05a-release.
+
+1. Changes to Bash
+
+a. Some changes to work around inlining differences between compilers.
+
+b. Added more prototypes for internal shell typedefs, to catch argument
+ passing errors when using pointers to functions.
+
+c. The `cd' builtin now fails in posix mode when a valid directory cannot be
+ constructed from a relative pathname argument and the $PWD using pathname
+ canonicalization, and the -P option has not been supplied. Previously,
+ the shell would attempt to use what the user typed, leading to weird
+ values for $PWD and discrepancies between the value of $PWD and the
+ actual working directory.
+
+d. The `cd' builtin now resets $PWD when canonicalization fails but a chdir
+ to the pathname passed as an argument succeeds (when not in posix mode).
+
+e. The `fc' builtin has been fixed, as POSIX requires, to use the closest
+ history position in range when given an out-of-range argument.
+
+f. The history file loading code was changed to allow lines to be saved in
+ the history list from the shell startup files.
+
+g. `history -s args' now works better in compound commands.
+
+h. The tilde expansion code was fixed to better recognize when it's being
+ invoked in an assignment context, which enables expansion after `='
+ and `:'.
+
+i. Fixed the command name completion code so a slash is no longer appended
+ to a single match if there happens to be a directory with that name in
+ $PWD.
+
+j. Fixed compound array assignment to no longer perform alias expansion, to
+ allow reserved words as array members, and to not produce extra output
+ when the `-v' option had been enabled.
+
+k. Fixed the programmable completion code to better handle newlines in lists
+ of possible completions (e.g., `complete -W').
+
+l. Removed the reserved words from the `bash-builtins' manual page.
+
+m. Parser error reporting now attempts to do a better job of identifying the
+ token in error rather than doing straight textual analysis.
+
+n. Fixes for Inf/NaN, locales, wide/multibyte characters and zero-length
+ arguments in the library snprintf(3) replacement.
+
+o. `read -e' no longer does command name completion on the first word on
+ the line being read.
+
+p. `select' now returns failure if the read of the user's selection fails.
+
+q. Fixed a bug that could cause a core dump when setting $PIPESTATUS.
+
+r. Fixes to not allocate so many job slots when the shell is running a loop
+ with job control enabled in a subshell of an interactive shell.
+
+s. Fixed a bug in the trap code that caused traps to be inherited by
+ command substitutions in some cases.
+
+t. Fixed a bug that could cause alias expansion to inappropriately expand
+ the word following the alias.
+
+u. Fixed a bug in the `kill' builtin that mishandled negative pid arguments.
+
+v. The parser is less lenient when parsing assignment statements where the
+ characters before the `=' don't comprise a valid identifier.
+
+w. The arithmetic expression evaluation code now honors the setting of the
+ `-u' option when expanding variable names.
+
+x. Fixed the arithmetic evaluation code to allow array subscripts to be
+ assigned (`let b[7]=42') and auto-incremented and auto-decremented
+ (e.g., b[7]++).
+
+y. Reimplemented the existing prompt string date and time expansions using
+ strftime(3), which changed the output of \@ in some locales.
+
+z. Fixed a bug that could cause a core dump when a special shell variable
+ (like RANDOM) was converted to an array with a variable assignment.
+
+aa. Fixed a bug that would reset the handler for a signal the user had
+ trapped to a function that would exit the shell when setting the exit
+ trap in a non-interactive shell.
+
+bb. Changed the execve(2) wrapper code to check whether or not a failing
+ command is a directory before looking at whether a `#!' interpreter
+ failed for some reason.
+
+cc. Fixed a bug in the command printing code so it no longer inserts a `;'
+ after a newline, which produces a syntax error when reused as input.
+
+dd. The code that expands $PS4 no longer inherits the `-x' flag.
+
+ee. The bash-specific completion functions may now take advantage of the
+ double-TAB and M-? features of the standard readline completion
+ functions.
+
+ff. The mail checking code no longer prints a message if the checked file's
+ size has not increased, even if the access time is less than the modification time.
+
+gg. Rewrote the variable symbol table code: there is now a stack of
+ contexts, each possibly including a separate symbol table; there can
+ be more than one temporary environment supplied to nested invocations
+ of `./source'; the temporary environments no longer require so much
+ special-case code; shell functions now handle the temporary environment
+ and local variables more consistently; function scope exit is faster now
+ that the entire symbol table does not have to be traversed to dispose of
+ local variables; it is now easier to push vars from the temporary
+ environment to the shell's variable table in posix mode; some duplicated
+ code has been removed.
+
+hh. Regularized the error message printing code; builtin_error is now called
+ more consistently, and common error message strings are handled by small
+ functions. This should make eventual message translation easier.
+
+ii. Error messages now include the line number in a script when the shell
+ is not interactive.
+
+jj. Array subscript expansion now takes place even when the array variable is
+ unset, so side effects will take place.
+
+kk. Fixed a bug in the SICGHLD child-reaping code so that it won't find
+ jobs already marked as terminated if the OS reuses pids quickly enough.
+
+ll. Fixed a bug that could cause a signal to not interrupt the `wait'
+ builtin while it was waiting for a background process to terminate.
+
+mm. A couple of changes to make it easier for multiple shells to share history
+ files using `history -n', `history -r', and `history -w'.
+
+nn. The `getopts' builtin always increments OPTIND to point to the next
+ option to be handled when an option is returned, whether it's valid
+ or not, as POSIX 1003.x-2001 requires.
+
+oo. Changed some parts of the expansion code to avoid allocating and
+ immediately freeing memory without using the results for anything.
+
+pp. The shell now keeps track of $IFS internally, updating its internal map
+ each time the variable is assigned a new value (or at local scope exit).
+ This saves thousands of hash lookups for IFS, which, while individually
+ cheap, add up.
+
+qq. Rewrote the hash table code: searching and insertion are much faster now,
+ and it uses a better string hashing function; augmented the function
+ interface to simplify other parts of the code and remove duplicated code
+
+rr. The shell now uses a simple, generic `object cache' for allocating and
+ caching words and word lists, which were the major users of
+ malloc/free.
+
+ss. Fixed the assignment statement parsing code to allow whitespace and
+ newlines in subscripts when performing array element assignment.
+
+tt. The shell now issues many fewer calls to sigprocmask and other signal
+ masking system calls.
+
+uu. Fixed the `test' and conditional command file comparison operators to
+ work right when one file has a non-positive timestamp and the other
+ does not exist.
+
+vv. Fixed some cases where the special characters '\001' and '\177' in the
+ values of variables or positional parameters caused incorrect expansion
+ results.
+
+2. Changes to Readline
+
+a. Fixed output of comment-begin character when listing variable values.
+
+b. Added some default key bindings for common escape sequences produced by
+ HOME and END keys.
+
+c. Fixed the mark handling code to be more emacs-compatible.
+
+d. A bug was fixed in the code that prints possible completions to keep it
+ from printing empty strings in certain circumstances.
+
+e. Change the key sequence printing code to print ESC as M\- if ESC is a
+ meta-prefix character -- it's easier for users to understand than \e.
+
+f. Fixed unstifle_history() to return values that match the documentation.
+
+g. Fixed the event loop (rl_event_hook) to handle the case where the input
+ file descriptor is invalidated.
+
+h. Fixed the prompt display code to work better when the application has a
+ custom redisplay function.
+
+i. Changes to make reading and writing the history file a little faster, and
+ to cope with huge history files without calling abort(3) from xmalloc.
+
+j. The vi-mode `S' and `s' commands are now undone correctly.
+
+3. New Features in Bash
+
+a. If set, TMOUT is the default timeout for the `read' builtin.
+
+b. `type' has two new options: `-f' suppresses shell function lookup, and
+ `-P' forces a $PATH search.
+
+c. New code to handle multibyte characters.
+
+d. `select' was changed to be more ksh-compatible, in that the menu is
+ reprinted each time through the loop only if REPLY is set to NULL.
+ The previous behavior is available as a compile-time option.
+
+e. `complete -d' and `complete -o dirnames' now force a slash to be
+ appended to names which are symlinks to directories.
+
+f. There is now a bindable edit-and-execute-command readline command,
+ like the vi-mode `v' command, bound to C-xC-e in emacs mode.
+
+g. Added support for ksh93-like [:word:] character class in pattern matching.
+
+h. The $'...' quoting construct now expands \cX to Control-X.
+
+i. A new \D{...} prompt expansion; passes the `...' to strftime and inserts
+ the result into the expanded prompt.
+
+j. The shell now performs arithmetic in the largest integer size the
+ machine supports (intmax_t), instead of long.
+
+k. If a numeric argument is supplied to one of the bash globbing completion
+ functions, a `*' is appended to the word before expansion is attempted.
+
+l. The bash globbing completion functions now allow completions to be listed
+ with double tabs or if `show-all-if-ambiguous' is set.
+
+m. New `-o nospace' option for `complete' and `compgen' builtins; suppresses
+ readline's appending a space to the completed word.
+
+n. New `here-string' redirection operator: <<< word.
+
+o. When displaying variables, function attributes and definitions are shown
+ separately, allowing them to be re-used as input (attempting to re-use
+ the old output would result in syntax errors).
+
+p. There is a new configuration option `--enable-mem-scramble', controls
+ bash malloc behavior of writing garbage characters into memory at
+ allocation and free time.
+
+q. The `complete' and `compgen' builtins now have a new `-s/-A service'
+ option to complete on names from /etc/services.
+
+r. `read' has a new `-u fd' option to read from a specified file descriptor.
+
+s. Fix the completion code so that expansion errors in a directory name
+ don't cause a longjmp back to the command loop.
+
+t. Fixed word completion inside command substitution to work a little more
+ intuitively.
+
+u. The `printf' %q format specifier now uses $'...' quoting to print the
+ argument if it contains non-printing characters.
+
+v. The `declare' and `typeset' builtins have a new `-t' option. When applied
+ to functions, it causes the DEBUG trap to be inherited by the named
+ function. Currently has no effect on variables.
+
+w. The DEBUG trap is now run *before* simple commands, ((...)) commands,
+ [[...]] conditional commands, and for ((...)) loops.
+
+x. The expansion of $LINENO inside a shell function is only relative to the
+ function start if the shell is interactive -- if the shell is running a
+ script, $LINENO expands to the line number in the script. This is as
+ POSIX-2001 requires.
+
+y. The bash debugger in examples/bashdb has been modified to work with the
+ new DEBUG trap semantics, the command set has been made more gdb-like,
+ and the changes to $LINENO make debugging functions work better. Code
+ from Gary Vaughan.
+
+z. New [n]<&word- and [n]>&word- redirections from ksh93 -- move fds (dup
+ and close).
+
+aa. There is a new `-l' invocation option, equivalent to `--login'.
+
+bb. The `hash' builtin has a new `-l' option to list contents in a reusable
+ format, and a `-d' option to remove a name from the hash table.
+
+4. New Features in Readline
+
+a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both
+ be bound to readline functions. Now the arrow keys may be used in vi
+ insert mode.
+
+b. When listing completions, and the number of lines displayed is more than
+ the screen length, readline uses an internal pager to display the results.
+ This is controlled by the `page-completions' variable (default on).
+
+c. New code to handle editing and displaying multibyte characters.
+
+d. The behavior introduced in bash-2.05a of deciding whether or not to
+ append a slash to a completed name that is a symlink to a directory has
+ been made optional, controlled by the `mark-symlinked-directories'
+ variable (default is the 2.05a behavior).
+
+e. The `insert-comment' command now acts as a toggle if given a numeric
+ argument: if the first characters on the line don't specify a
+ comment, insert one; if they do, delete the comment text
+
+f. New application-settable completion variable:
+ rl_completion_mark_symlink_dirs, allows an application's completion
+ function to temporarily override the user's preference for appending
+ slashes to names which are symlinks to directories.
+
+g. New function available to application completion functions:
+ rl_completion_mode, to tell how the completion function was invoked
+ and decide which argument to supply to rl_complete_internal (to list
+ completions, etc.).
+
+h. Readline now has an overwrite mode, toggled by the `overwrite-mode'
+ bindable command, which could be bound to `Insert'.
+
+i. New application-settable completion variable:
+ rl_completion_suppress_append, inhibits appending of
+ rl_completion_append_character to completed words.
+
+j. New key bindings when reading an incremental search string: ^W yanks
+ the currently-matched word out of the current line into the search
+ string; ^Y yanks the rest of the current line into the search string,
+ DEL or ^H deletes characters from the search string.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-release,
+and the previous version, bash-2.05a-rc1.
+
+1. Changes to Bash
+
+a. Fixed the `printf' builtin so that the variable name supplied as an
+ argument to a %n conversion must be a valid shell identifier.
+
+b. Improved the random number generator slightly.
+
+c. Changes to configuration to not put -I/usr/include into $CFLAGS, since
+ it messes up some includes.
+
+d. Corrected description of POSIXLY_CORRECT in man page and info manual.
+
+e. Fixed a couple of cases of incorrect function prototypes that sneaked
+ through and caused compilation problems.
+
+f. A few changes to avoid potential core dumps in the programmable completion
+ code.
+
+g. Fixed a configure problem that could cause a non-existent file to show
+ up in LIBOBJS.
+
+h. Fixed a configure problem that could cause siglist.o to not be built when
+ required.
+
+i. Changes to the strtoimax and strtoumax replacement functions to work
+ around buggy compilers.
+
+j. Fixed a problem with the snprintf replacement function that could
+ potentially cause a core dump.
+
+2. Changes to Readline
+
+a. Fixed a locale-specific problem in the vi-mode `goto mark' command.
+
+b. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
+ include file problems.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-rc1,
+and the previous version, bash-2.05a-beta1.
+
+1. Changes to Bash
+
+a. Fixed the snprintf replacement to correctly implement the `alternate form'
+ of the %g and %G conversions.
+
+b. Fixed snprintf to correctly handle the optional precision with the %g and
+ %G conversions.
+
+c. Fixed the arithmetic evaluation code to correct the values of `@' and `_'
+ when translating base-64 constants (they were backwards).
+
+d. New library functions for formatting long and long long ints.
+
+e. Fixed a few places where negative array subscripts could have occurred,
+ mostly as the result of systems using signed characters.
+
+f. Fixed a few places that assumed a pid_t was no wider than an int.
+
+g. Fixed the `maildir' mail checking code to work on systems where a
+ `struct stat' doesn't include an `st_blocks' member.
+
+h. Fixed snprintf to make `unsigned long long' conversion formats (%llu)
+ work better.
+
+i. Fixed snprintf to not print a sign when asked to do an unsigned conversion.
+
+j. Made configure changes to avoid compiling empty source files in lib/sh.
+
+k. New replacement functions (if necessary) for strtoull, strtoll, strtoimax,
+ strtoumax.
+
+l. The `printf' builtin now handles the `ll' and `j' length modifiers
+ directly, since they can affect the type and width of the argument
+ passed to printf(3).
+
+m. Renamed a number of the bash-specific autoconf macros in aclocal.m4 to
+ have more sytematic naming, with accompanying changes to configure.in.
+
+n. Fixed snprintf to handle long doubles and the %a/%A conversions by
+ falling back to sprintf, as long as sprintf supports them.
+
+o. Fixed return value from vsnprintf/snprintf to be the number of characters
+ that would have been printed, even if that number exceeds the buffer
+ size passed as an argument.
+
+p. Bash no longer attempts to define its own versions of some ctype macros
+ if they are implemented as functions in libc but not as macros in
+ <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.
+
+b. bashbug now uses $TMPDIR, defaulting to /tmp, and uses mktemp(1) more
+ portably.
+
+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.
+
+k. Fixed non-interactive shell initialization problem when bash started as
+ `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.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-beta2,
+and the previous version, bash-2.05-beta1.
+
+1. Changes to Bash
+
+a. Fixed a bug in the arithmetic evaluation code so that a^=b is supported.
+
+b. Fixed startup so posixly_correct is retained across subshells begun to
+ execute scripts without a leading `#!'.
+
+c. Fixed a bug that caused $(< file) to not work in a (...) subshell.
+
+d. Added config support for Linux running on the IBM S390.
+
+e. Fixed a bug that caused bash to get its input pointer out of sync when
+ reading commands through a pipe and running a command with standard
+ input redirected from a file.
+
+f. Made a change so that command completion now makes about half as many
+ stat(2) calls when searching the $PATH.
+
+g. Fixed a bug that caused variable assignments preceding `return' to not
+ be propagated to the shell environment in POSIX mode.
+
+h. Fixed a bug with ${parameter[:]?word} -- tilde expansion was not performed
+ on `word'.
+
+i. In POSIX mode, `break' and `continue' do not complain and return success
+ if called when the shell is not executing a loop.
+
+j. Fixed `bash -o posix' to work the same as `bash --posix'.
+
+k. Fixed a bug where variable assignments preceding `eval' or `source/.'
+ would not show up in the environment exported to subshells run by the
+ commands.
+
+l. In POSIX mode, shells started to execute command substitutions inherit
+ the value of the `-e' option from their parent shell.
+
+m. In POSIX mode, aliases are expanded even in non-interactive shells.
+
+n. Changed some of the job control messages to display the text required by
+ POSIX.2 when the shell is in POSIX mode.
+
+o. Fixed a bug in `test' that caused it to occasionally return incorrect
+ results when non-numeric arguments were supplied to `-t'.
+
+2. Changes to Readline
+
+a. Some changes were made to avoid gcc warnings with -Wall.
+
+b. rl_get_keymap_by_name now finds keymaps case-insensitively, so
+ `set keymap EMACS' works.
+
+c. The history file writing and truncation functions now return a useful
+ status on error.
+
+d. Fixed a bug that could cause applications to dereference a NULL pointer
+ if a NULL second argument was passed to history_expand().
+
+3. New Features in Bash
+
+a. doc/readline.3 has been moved to the readline distribution.
+
+4. New Features in Readline
+
+a. New function, rl_get_screen_size (int *rows, int *columns), returns
+ readline's idea of the screen dimensions.
+
+b. The timeout in rl_gather_tyi (readline keyboard input polling function)
+ is now settable via a function (rl_set_keyboard_input_timeout()).
+
+c. Renamed the max_input_history variable to history_max_entries; the old
+ variable is maintained for backwards compatibility.
+
+d. The list of characters that separate words for the history tokenizer is
+ now settable with a variable: history_word_delimiters. The default
+ value is as before.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-beta1,
+and the previous version, bash-2.05-alpha1.
+
+1. Changes to Bash
+
+a. Changes to allow shared library and object building on the GNU Hurd.
+
+b. Fixes to the way exported functions are placed into the environment and
+ cached.
+
+c. The globbing library once again respects locales when processing ranges
+ in bracket expressions while doing pattern matching.
+
+d. System-specific configuration changes for: Tru 64, Interix
+
+e. Bashbug now uses /usr/bin/editor as one of the editing alternatives, and
+ will use mktemp(1) or tempfile(1), if present, for temporary file creation.
+
+f. Bash no longer performs a binary file check on a script argument that's
+ really a tty (like /dev/fd/0 or /dev/stdin).
+
+g. Fixed a bug in the execution of shell scripts that caused the effects of
+ $BASH_ENV to be undone in some cases.
+
+h. Fixed several bugs that made `bash [-i] /dev/stdin' not work correctly.
+
+i. Several changes to the job control code to avoid some signal state
+ manipulation.
+
+j. The Bash malloc no longer blocks signals as often, which should make it
+ faster.
+
+k. Fixed a parsing bug that did not allow backslash to escape a single quote
+ inside a $'...' construct.
+
+l. Fixed a bug that caused things like ${var:=$'value'} to be parsed
+ incorrectly. This showed up in newer versions of autoconf.
+
+m. Fixed a bug in the bash-specific readline initialization that caused
+ key bindings to bash-specific function names appearing in .inputrc to
+ not be honored.
+
+n. Bash now sets the file descriptor it uses to save the file descriptor
+ opened on a shell script to close on exec.
+
+o. Fixed a bug in the prompt string decoding that caused it to misbehave
+ when presented an octal sequence of fewer than three characters.
+
+p. Fixed the `test' builtin to return an error if `[' is supplied a single
+ argument that is not `]'.
+
+q. Fixed a bug that caused subshells started to run executable shell scripts
+ without a leading `#!' to incorrectly inherit an argument list preceding
+ a shell builtin (like such a script called from a script sourced with `.',
+ where there were variable assignments preceding the `.' command)
+
+r. Fixed a bug that caused changes to variables supplied in an assignment
+ statement preceding a shell builtin to not be honored (like a script
+ run with `.').
+
+s. HOSTTYPE, OSTYPE, and MACHTYPE are set only if they do not have values
+ when the shell is started.
+
+t. Fixed a bug that caused SIGINT to kill shell scripts after the script
+ called `wait'.
+
+u. The `fc' builtin now tries to create its temporary files in the directory
+ named by $TMPDIR.
+
+v. Bash no longer calls any Readline functions or uses any Readline variables
+ not declared in readline.h.
+
+w. Fixed a bug that caused some substitutions involving $@ to not be split
+ correctly, especially expansions of the form ${paramterOPword}.
+
+x. SSH2_CLIENT is now treated like SSH_CLIENT and not auto-exported if it
+ appears in the initial environment.
+
+y. Fixed a couple of problems with shell scripts without a leading `#!'
+ being executed out of shell functions that could cause core dumps if
+ such a script attempted to execute `return'.
+
+z. Fixed a problem with the `-nt' and `-ot' binary operators for the
+ `test/[' builtin and the `[[' conditional command that caused wrong
+ return values if one of the file arguments did not exist.
+
+aa. Fixed a bug that caused non-interactive shells which had previously
+ executed `shopt -s expand_aliases' to fail to expand aliases in a
+ command like `(command) &'.
+
+2. Changes to Readline
+
+a. Changes to make most (but not yet all -- there is still crlf()) of the
+ exported readline functions declared in readline.h have an rl_ prefix.
+
+b. More `const' changes in function arguments, mostly for completion
+ functions.
+
+c. Fixed a bug in rl_forward that could cause the point to be set to before
+ the beginning of the line in vi mode.
+
+d. Fixed a bug in the callback read-char interface to make it work when a
+ readline function pushes some input onto the input stream with
+ rl_execute_next (like the incremental search functions).
+
+e. Fixed a file descriptor leak in the history file manipulation code that
+ was tripped when attempting to truncate a non-regular file (like
+ /dev/null).
+
+f. Some existing variables are now documented and part of the public
+ interface (declared in readline.h): rl_explict_arg, rl_numeric_arg,
+ rl_editing_mode, rl_last_func.
+
+g. Renamed rltty_set_default_bindings to rl_tty_set_default_bindings and
+ crlf to rl_crlf, so there are no public functions declared in readline.h
+ without an `rl_' prefix. The old functions still exist for backwards
+ compatibility.
+
+3. New Features in Bash
+
+a. A new loadable builtin, realpath, which canonicalizes and expands symlinks
+ in pathname arguments.
+
+b. When `set' is called without options, it prints function defintions in a
+ way that allows them to be reused as input. This affects `declare' and
+ `declare -p' as well.
+
+4. New Features in Readline
+
+a. New application-callable function rl_set_prompt(const char *prompt):
+ expands its prompt string argument and sets rl_prompt to the result.
+
+b. New application-callable function rl_set_screen_size(int rows, int cols):
+ public method for applications to set readline's idea of the screen
+ dimensions.
+
+c. The history example program (examples/histexamp.c) is now built as one
+ of the examples.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-alpha1,
+and the previous version, bash-2.04-release.
+
+1. Changes to Bash
+
+a. A fix was made to allow newlines in compond array assignments.
+
+b. configure now checks for real-time signals with unusable values.
+
+c. Interactive shells no longer exit if a substitution fails because of an
+ unset variable within a sourced file.
+
+d. Fixed a problem with incorrect matching of extended glob patterns when
+ doing pattern substitution.
+
+e. `{' is now quoted by the completion code when it appears in a filename.
+
+f. Fixed an error in pattern matching that caused the matcher to not
+ correctly skip the rest of a bracket expression after a character
+ matched.
+
+g. Fixed a bug in the IFS word splitting code to make a non-whitespace IFS
+ character preceded by IFS whitespace part of the current delimiter rather
+ than generating a separate field.
+
+h. The {!prefix@} expansion now generates separate words, analogous to $@,
+ when double-quoted.
+
+i. Command substitution now ignores NUL bytes in the command output, and the
+ parser ignores them on input.
+
+j. A fix was made to the job control code to prevent hanging processes when
+ the shell thinks background processes are running but the kernel returns
+ -1/ECHILD from waitpid().
+
+k. `pwd' now prints an error message if the write fails when displaying the
+ current directory.
+
+l. When in POSIX mode, the shell prints trap dispostions without a leading
+ `SIG' in the signal specification.
+
+m. Fixed a parser bug that caused the current command's line count to be
+ messed up by a compound array assignment.
+
+n. Fixed a bug in the unwind-protect code that caused bad behavior on machines
+ where ints and pointers are not the same size.
+
+o. System-specific configure changes for: MacOS X.
+
+p. Changes for Cygwin to translate \r\n and \r to \n and to set file
+ descriptors used for reading input to text mode in various places.
+
+q. Fixed a bug that caused `!' to occasionally not be honored when in
+ a (...) subshell.
+
+r. Bash no longer assumes that getcwd() will return any useful error message
+ in the buffer passed as an argument if the call fails.
+
+s. The `source', `.', and `fc' builtins no longer check whether a file is
+ binary before reading commands from it.
+
+t. Subshells no longer turn off job control when they exit, since that
+ sometimes resulted in the terminal being reset to the wrong process
+ group.
+
+u. The history code no longer tries to save the second and subsequent lines
+ of a multi-line command if the first line was not saved.
+
+v. The history saving code now does a better job of saving blank lines in a
+ multi-line command.
+
+w. Removed a `feature' that made `ulimit' silently translate `unlimited' to
+ the current hard limit, which obscured some kernel error returns.
+
+x. Fixed the grammar so that `}' is recognized as a reserved word after
+ another reserved word, rather than requiring a `;' or newline. This
+ means that constructs like
+
+ { { echo a b c ; } }
+
+ work as expected.
+
+y. Conditional commands ([[...]]) now perform tilde expansion on their
+ arguments.
+
+z. Noted in the documentation that `set -a' will cause functions to be
+ exported if they are defined after `set -a' is executed.
+
+aa. When an interactive login shell starts, if $PWD and $HOME refer to the
+ same directory but are not the same string, $PWD is set to $HOME.
+
+bb. Fixed `printf' to handle invalid floating point numbers better.
+
+cc. Temporary files are now created with random filenames, to improve security.
+
+dd. The readline initialization code now binds the custom bash functions and
+ key bindings after the readline defaults are set up.
+
+ee. Fixed the `source' builtin to no longer overwrite a shell function's
+ argument list, even if the sourced file changes the positional parameters.
+
+ff. A bug fix was made in the expansion of `$*' in contexts where it should
+ not be split, like assignment statements.
+
+gg. Fixed a bug in the parameter substring expansion to handle conditional
+ arithmetic expressions ( exp ? val1 : val2 ) without cutting the expression
+ off at the wrong `:'.
+
+hh. The `<>' redirection is no longer subject to the current setting of
+ `noclobber', as POSIX.2 specifies.
+
+ii. Fixed a bug in the conditional command parsing code that caused expressions
+ in parentheses to occasionally be parsed incorrectly.
+
+jj. Fixed a bug in the ((...)) arithmetic command to allow do...done or
+ {...} to follow the )) without an intervening list terminator.
+
+kk. `printf' now treats `\E' the same as `\e' when performing backslash escape
+ expansion for the `%b' format specifier.
+
+ll. When in POSIX mode, the shell no longer searches the current directory for
+ a file to be sourced with `.' or `source' if `.' is not in $PATH.
+
+mm. Interactive comments are no longer turned off when POSIX mode is disabled.
+
+nn. The UID, EUID, HOSTNAME variables are not set if they are in the shell's
+ environment when it starts up.
+
+oo. Fixed a bug in the `command' builtin so the effect of a command like
+ `command exec 4<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.
+

+and the previous version, bash-2.04-beta5.
+
+1. Changes to Bash

+a. Better compile-time and configure-time checks for the necessity of
+ inet_aton().
+
+b. A bug was fixed in the expansion of "${@:-}" when there are positional
+ parameters.
+
+c. A typo was fixed in the output of `complete'.
+
+d. The matches generated for a word by the `-W' argument to complete and
+ compgen are now matched against the word being completed, and only
+ matches are returned as the result.
+
+e. Some fixes were made for systems which do not restart read(2) when a
+ signal caught by bash is received.
+
+f. A bug was fixed which caused the umask to be set to 0 when an invalid
+ symbolic mode mask was parsed.
+
+g. Fixed a bug that could cause a core dump if a SIGCHLD was received while

+ in which the cursor is between words are handled a bit better.
+
+2. Changes to Readline
+
+a. rl_funmap_names() is now documented.
+
+3. New Features in Bash
+
+a. The LC_NUMERIC variable is now treated specially, and used to set the

+ displays floating-point numbers.
+
+------------------------------------------------------------------------------

+ non-Unix systems.
+
+b. Fixed a bug where the current prompt would be set to $PS2 at startup.
+
+c. The shell script that tests an already-installed version was changed to
+ remove the directory it created its test programs in at exit.
+
+d. Several changes were made to the code that tokenizes an input line for
+ the programmable completion code. Shell metacharacters will now appear
+ as individual words in the word list passed to the completion functions.
+ Some of the example completion shell functions were changed to understand
+ redirection operators.
+
+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
+ abnormal termination (and consequently resetting the terminal attributes)
+ was fixed.
+
+j. Fixed a bug that caused $PS2 to be displayed after PROMPT_COMMAND was
+ executed.
+
+2. Changes to Readline
+
+1. Fixed a bug in a C preprocessor define that caused the keypad control
+ functions to be compiled out for all platforms except DJGPP.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta4,
+and the previous version, bash-2.04-beta3.
+
+1. Changes to Bash
+
+a. A couple of changes were made to the redirection to attempt to avoid
+ race conditions and malicious file replacement.
+
+2. A change was made to the string evaluation code (used for command
+ substitution, `eval', and the `.' builtin) to fix an obscure core
+ dump on alpha machines.
+
+3. A bug that caused $LINENO to be wrong when executing arithmetic 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.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta3,
+and the previous version, bash-2.04-beta2.
+
+1. Changes to Bash
+
+a. Bash should run the appropriate startup files when invoked by ssh2.
+
+b. Fixed a bug in the parsing of conditional commands that could cause a
+ core dump.
+
+c. Fixed a bug in parsing job specifications that occasionally caused
+ core dumps when an out-of-range job was referenced.
+
+d. Fixed the `type' and `command' builtins to do better reporting of
+ commands that are not found in $PATH or the hash table.
+
+e. Fixed a POSIX.2 compliance problem in the command builtin -- commands
+ are supposed to be reported as full pathnames.
+
+f. The `echo' builtin now returns failure if a write error occurs.
+
+g. Fixed a bug which caused the locale to not be reset correctly when
+ LC_ALL was unset.
+
+h. Changed description of `getopts' in man page and reference manual to make
+ it clear that option characters may be characters other than letters.
+
+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
+ closing brace.
+
+s. Changed the tilde expansion code for Cygwin systems to avoid creating
+ pathnames beginning with `//' if $HOME == `/'.
+
+t. Fixed a couple of autoconf tests to avoid creating files with fixed names
+ in /tmp.
+
+u. The `trap' and `kill' builtins now know the names of the POSIX.1b real-
+ time signals on systems which support them.
+
+2. Changes to Readline
+
+a. Fixed a problem with the single-quote quoting function that could cause
+ buffer overflows.
+
+b. Fixed a bug that caused incorrect `stat characters' to be printed if
+ 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
+ `--enable-xpg-echo-default'. The old option is still there for backwards
+ compatibility.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta2,
+and the previous version, bash-2.04-beta1.
+
+1. Changes to Bash
+
+a. Fixed a bug that could cause pipes to be closed inappropriately in
+ some obscure cases.
+
+b. Fixed a bug that caused creation of the exported environment to clobber
+ the current command string if there were any exported shell functions.
+
+c. Some changes were made to reduce bash's memory usage.
+
+d. Fixed a problem with programmable completion and filenames to be
+ completed containing quote characters.
+
+e. Changed the code the removes named pipes created for the <(...) and >(...)
+ expansions to defer removal until after any current shell function has
+ finished executing.
+
+f. Fixed a bug in `select' which caused it to not handle the `continue'
+ builtin correctly.
+
+g. Autoconf tests added for cygwin32 and mingw32.

+a. The `--with-bash-malloc' configure option replaces `--with-gnu-malloc'
+ (which is still there for backwards compatibility).
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta1,
+and the previous version, bash-2.04-alpha1.
+
+1. Changes to Bash
+
+a. Fixed a bug in the programmable completion code that occurred when
+ trying to complete command lines containing a `;' or `@'.
+
+b. The file descriptor from which the shell is reading a script is now
+ moved to a file descriptor above the user-addressible range.
+
+c. Changes to `printf' so that it can handle integers beginning with 0
+ or 0x as octal and hex, respectively.
+
+d. Fixes to the programmable completion code so it handles nonsense like
+ `compgen -C xyz' gracefully.
+
+e. The shell no longer modifies the signal handler for SIGPROF, allowing
+ profiling again on certain systems.
+
+f. The shell checks for a new window size, if the user has requested it,
+ after a process exits due to a signal.
+
+g. Fixed a bug with variables with null values in a program's temporary
+ environment and the bash getenv() replacement.
+
+h. `declare' and the other builtins that take variable assignments as
+ arguments now honor `set -a' and mark modified variables for export.
+
+i. Some changes were made for --dump-po-strings mode when writing strings
+ with embedded newlines.
+
+j. The code that caches export strings from the initial environment now
+ duplicates the string rather than just pointing into the environment.
+
+k. The filename completion quoting code now uses single quotes by default
+ if the filename being completed contains newlines, since \<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.
+
+m. Configuration changes were made for: Rhapsody, Mac OS, FreeBSD-3.x.
+
+n. Fixed a problem with hostname-to-ip-address translation in the
+ /dev/(tcp|udp)/hostname/port redirection code.
+
+o. The texinfo manual has been reorganized slightly.
+
+p. Filename generation (globbing) range comparisons in bracket expressions
+ no longer use strcoll(3) even if it is available, since it has unwanted
+ effects in certain locales.
+
+q. 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.
+
+dd. A bug was fixed that occasionally caused traps to mess up the parser
+ state.
+
+ee. `bashbug' now honors user headers in the mail message it sends.
+
+ff. A bug was fixed that caused the `:p' history modifier to not print the
+ history expansion if the `histverify' option was set.
+
+2. Changes to Readline
+
+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.
+

+ fewer read(2) system calls.
+
+n. The expansion of $- will include `c' and `s' when those options are

+ completion understands quotes better, and completion now works in certain
+ unclosed $(... constructs.
+
+p. The arithmetic expansion code was fixed to not need the value of a
+ variable being assigned a value (fixes the "ss=09; let ss=10" bug).
+

+
+2. Changes to Readline
+
+a. The history library tries to truncate the history file only if it is a
+ regular file.

+i. The quoted-insert code will now insert tty special chars like ^C.
+
+j. A bug was fixed that caused the display code to reference memory before
+ the start of the prompt string.
+
+k. More support for __EMX__ (OS/2).
+
+l. A bug was fixed in readline's signal handling that could cause infinite
+ recursion in signal handlers.

+
+n. The vi-mode code now gets characters via the application-settable value
+ of rl_getc_function rather than calling rl_getc directly.
+
+3. New Features in Bash
+
+a. The history builtin has a `-d offset' option to delete the history entry
+ at position `offset'.
+
+b. The prompt expansion code has two new escape sequences: \j, the number of
+ active jobs; and \l, the basename of the shell's tty device name.
+
+c. The `bind' builtin has a new `-x' option to bind key sequences to shell
+ commands.
+
+d. There is a new shell option, no_empty_command_completion, which, when
+ enabled, disables command completion when TAB is typed on an empty line.
+
+e. The `help' builtin has a `-s' option to just print a builtin's usage
+ synopsys.
+
+f. There are several new arithmetic operators: id++, id-- (variable
+ post-increment/decrement), ++id, --id (variabl pre-increment/decrement),
+ expr1 , expr2 (comma operator).
+
+g. There is a new ksh-93 style arithmetic for command:

+ -n nchars only read nchars from input instead of a full line
+ -d delim read until delim rather than newline
+ -s don't echo input chars as they are read
+
+i. The redirection code now handles several filenames specially:
+ /dev/fd/N, /dev/stdin, /dev/stdout, and /dev/stderr, whether or
+ not they are present in the file system.
+
+j. The redirection code now recognizes pathnames of the form
+ /dev/tcp/host/port and /dev/udp/host/port, and tries to open a socket
+ of the appropriate type to the specified port on the specified host.
+
+k. The ksh-93 ${!prefix*} expansion, which expands to the names of all
+ shell variables whose names start with prefix, has been implemented.
+
+l. There is a new dynamic variable, FUNCNAME, which expands to the name of
+ a currently-executing function. Assignments to FUNCNAME have no effect.
+
+m. The GROUPS variable is no longer readonly; assignments to it are silently
+ discarded. This means it can be unset.
+
+4. New Features in Readline
+
+a. Parentheses matching is now always compiled into readline, and enabled
+ or disabled when the value of the `blink-matching-paren' variable is
+ changed.
+

+ in the readline buffer if the second or subsequent search fails.
+
+f. New function for use by applications: rl_on_new_line_with_prompt, used
+ when an application displays the prompt itself before calling readline().
+
+g. New variable for use by applications: rl_already_prompted. An application
+ that displays the prompt itself before calling readline() must set this to
+ a non-zero value.

+
+h. Fixed a bug that manifested itself when shell functions were called
+ between calls to `getopts'.
+

+ replacement string to be prefixed to the search string, and a bare
+ `%' causes the replacement string to be appended to the search string.
+
+j. Fixed a bug in the command execution code that caused child processes
+ to occasionally have the wrong value for $!.
+
+2. Changes to Readline
+
+a. Added code to the history library to catch history substitutions using
+ `&' without a previous history substitution or search having been
+ performed.

+g. A fix was made to the command printing code to ensure that redirections
+ following compound commands have a space separating them from the rest
+ of the command.
+
+h. The pathname canonicalization code was changed to produce fewer leading
+ `//' sequences, since those are interpreted as network file system
+ pathnames on some systems.
+
+i. A fix was made so that loops containing `eval' commands in commands passed
+ to `bash -c' would not exit prematurely.
+
+j. Some changes were made to the job reaping code when the shell is not
+ interactive, so the shell will retain exit statuses longer for examination
+ by `wait'.
+
+k. A fix was made so that `jobs | command' works again.
+
+l. The erroneous compound array assignment var=((...)) is now a syntax error.
+
+m. A change was made to the dynamic loading code in `enable' to support

+
+a. A fix was made to the completion code in which a typo caused the wrong
+ value to be passed to the function that computed the longest common
+ prefix of the list of matches.
+
+b. The completion code now checks the value of rl_filename_completion_desired,
+ which is set by application-supplied completion functions to indicate
+ that filename completion is being performed, to decide whether or not to
+ call an application-supplied `ignore completions' function.
+
+3. New Features in Bash
+
+a. A change was made to the startup file code so that any shell begun with
+ the `--login' option, even non-interactive shells, will source the login
+ shell startup files.
+
+4. New Features in Readline

+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.03-alpha,
+and the previous version, bash-2.02.1-release.

+ from the net.
+
+c. The configure tests that determine which native type is 32 bits were
+ changed to not require a compiled program.
+
+d. Fixed a bug in shell_execve that could cause memory to be freed twice
+ after a failed exec.
+
+e. The `printf' test uses `diff -a' if it's available to prevent confusion
+ due to the non-ascii output.
+
+f. Shared object configuration is now performed by a shell script,
+ support/shobj-conf, which generates values to be substituted into
+ makefiles by configure.
+
+g. Some changes were made to `ulimit' to avoid the use of RLIM_INVALID as a
+ return value.
+
+h. Changes were made to `ulimit' to work around HPUX 9.x's peculiar
+ handling of RLIMIT_FILESIZE.
+
+i. Some new loadable builtins were added: id, printenv, sync, whoami, push,
+ mkdir. `pushd', `popd', and `dirs' can now be built as regular or
+ loadable builtins from the same source file.
+
+j. Changes were made to `printf' to handle NUL bytes in the expanded format
+ string.
+
+k. The various `make clean' Makefile targets now descend into lib/sh.
+
+l. The `type' builtin was changed to use the internal `getopt' so that things
+ like `type -ap' work as expected.
+
+m. There is a new configuration option, --with-installed-readline, to link
+ bash with a locally-installed version of readline. Only readline version
+ 4.0 and later releases can support this. Shared and static libraries
+ are supported. The installed include files are used.
+
+n. There is a new autoconf macro used to find which basic type is 64 bits.
+
+o. Dynamic linking and loadable builtins should now work on SCO 3.2v5*,
+ AIX 4.2 with gcc, Unixware 7, and many other systems using gcc, where
+ the `-shared' options works correctly.
+
+p. A bug was fixed in the bash filename completion code that caused memory to
+ be freed twice if a directory name containing an unset variable was
+ completed and the -u option was set.
+
+q. The prompt expansion code now quotes the `$' in the `\$' expansion so it
+ 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.
+
+t. Changes to the default prompt strings if prompt string decoding is not
+ compiled into the shell.

+ precede the `time' reserved word.
+
+v. The shell may now be cross-built for BeOS as well as cygwin32.
+
+w. The conditional command execution code now treats `=' the same as `=='
+ for deciding when to perform pattern matching.
+
+x. The `-e' option no longer causes the shell to exit if a command exits
+ with a non-zero status while running the startup files.

+ the format string without a conversion character (e.g. `%h').
+
+z. Array assignments of the form a=(...) no longer show up in the history
+ list.
+
+aa. The parser was fixed to obey the POSIX.2 rules for finding the closing
+ `}' in a ${...} expression.
+
+bb. The history file is now opened with mode 0600 rather than 0666, so bash
+ no longer relies on the user's umask being set appropriately.
+
+cc. Setting LANG no longer causes LC_ALL to be assigned a value; bash now
+ 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.
+
+c. Some changes were made to the key binding code to fix memory leaks and
+ better support Win32 systems.
+
+d. Fixed a silly typo in the paren matching code -- it's microseconds, not
+ 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
+ source files uncovered by the use of prototypes.
+
+g. The maximum numeric argument is now clamped at 1000000.
+
+h. Fixes to rl_yank_last_arg to make it behave better.
+
+i. Fixed a bug in the display code that caused core dumps if the prompt
+ string length exceeded 1024 characters.
+
+j. The menu completion code was fixed to properly insert a single completion
+ if there is only one match.
+
+k. A bug was fixed that caused the display code to improperly display tabs
+ after newlines.
+
+3. New Features in Bash
+
+a. New `shopt' option, `restricted_shell', indicating whether or not the
+ shell was started in restricted mode, for use in startup files.
+
+b. Filename generation is now performed on the words between ( and ) in
+ array assignments (which it probably should have done all along).
+
+c. OLDPWD is now auto-exported, as POSIX.2 seems to require.
+
+d. ENV and BASH_ENV are read-only variables in a restricted shell.
+
+4. New Features in Readline
+
+a. Many changes to the signal handling:
+ o Readline now catches SIGQUIT and cleans up the tty before returning;
+ o A new variable, rl_catch_signals, is available to application writers
+ to indicate to readline whether or not it should install its own
+ signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+ SIGTTIN, and SIGTTOU;
+ o A new variable, rl_catch_sigwinch, is available to application
+ writers to indicate to readline whether or not it should install its
+ own signal handler for SIGWINCH, which will chain to the calling
+ applications's SIGWINCH handler, if one is installed;
+ o There is a new function, rl_free_line_state, for application signal
+ handlers to call to free up the state associated with the current
+ line after receiving a signal;
+ o There is a new function, rl_cleanup_after_signal, to clean up the
+ display and terminal state after receiving a signal;
+ o There is a new function, rl_reset_after_signal, to reinitialize the
+ terminal and display state after an application signal handler
+ returns and readline continues
+
+b. There is a new function, rl_resize_terminal, to reset readline's idea of
+ the screen size after a SIGWINCH.
+
+c. New public functions: rl_save_prompt and rl_restore_prompt. These were
+ previously private functions with a `_' prefix.
+
+d. New function hook: rl_pre_input_hook, called just before readline starts
+ reading input, after initialization.
+
+e. New function hook: rl_display_matches_hook, called when readline would
+ display the list of completion matches. The new function
+ rl_display_match_list is what readline uses internally, and is available
+ for use by application functions called via this hook.
+
+f. New bindable function, delete-char-or-list, like tcsh.
+

+b. Fixed a bug that could cause a core dump when here documents contained
+ more than 1000 characters.
+
+c. Fixed a bug that caused a CDPATH entry of "" to not be treated the same

+i. Fixed a bug that caused core dumps when using conditional commands in
+ shell functions.
+
+j. Fixed a bug that caused the printf builtin to loop forever if the format
+ string did not consume any of the arguments.

+k. Fixed a bug in the parameter expansion code that caused "$@" to be
+ incorrectly split if $IFS did not contain a space character.
+
+l. Fixed a bug that could cause a core dump when completing hostnames if
+ the number of matching hostnames was an exact multiple of 16.
+
+m. Fixed a bug that caused the shell to fork too early when a command
+ such as `%2 &' was given.
+
+2. Changes to Readline
+
+a. Fixed a problem with redisplay that showed up when the prompt string was
+ longer than the screen width and the prompt contained invisible characters.

+b. Changes were made to the generated `info' files so that `install-info'
+ works correctly.
+
+c. PWD is now auto-exported.
+
+d. A fix was made to the pipeline code to make sure that the shell forks
+ to execute simple commands consisting solely of assignment statements.
+
+e. Changes to the test suite for systems with 14-character filenames.
+
+f. The default sizes of some internal hash tables have been made smaller
+ to reduce the shell's memory footprint.
+
+g. The `((...))' arithmetic command is now executed directly instead of
+ being translated into `let "..."'.
+
+h. Fixes were made to the expansion code so that "$*", "$@", "${array[@]}",
+ and "${array[@]}" expand correctly when IFS does not contain a space
+ character, is unset, or is set to NULL.
+
+i. The indirect expansion code (${!var}) was changed so that the only
+ valid values of `var' are variable names, positional parameters, `#',
+ `@', and `*'.
+
+j. An arithmetic expression error in a $((...)) expansion now causes a
+ non-interactive shell running in posix mode to exit.
+
+k. Compound array assignment now splits the words within the parentheses
+ on shell metacharacters like the parser would before expansing them
+ and performing the assignment. This is for compatibility with ksh-93.
+
+l. The internal shell backslash-quoting code (used in the output of `set'
+ and completion) now quotes tildes if they appear at the start of the
+ string or after a `=' or `:'.
+
+m. A couple of bugs with `shopt -o' were fixed.
+
+n. `bash +o' now displays the same output as `set +o' before starting an
+ interactive shell.
+
+o. A bug that caused command substitution and the `eval' builtin to
+ occasionally free memory twice when an error was encountered was fixed.
+
+p. The filename globbing code no longer requires read permission for a
+ directory when the filename to be matched does not contain any globbing
+ characters, as POSIX.2 specifies.
+
+q. A bug was fixed so that the job containing the last asynchronous
+ process is not removed from the job table until a `wait' is executed
+ for that process or another asynchronous process is started. This
+ satisfies a POSIX.2 requirement.
+
+r. A `select' bug was fixed so that a non-numeric user response is treated
+ the same as a numeric response that is out of range.
+
+s. The shell no longer parses the value of SHELLOPTS from the environment
+ if it is restricted, running setuid, or running in `privileged mode'.
+
+t. Fixes were made to enable large file support on systems such as
+ Solaris 2.6, where the size of a file may be larger than can be held
+ in an `int'.
+
+u. The filename hashing code was fixed to not add `./' to the beginning of
+ filenames which already begin with `./'.
+
+v. The configure script was changed so that the GNU termcap library is not
+ compiled in if `prefer-curses' has been specified.
+
+w. HISTCONTROL and HISTIGNORE are no longer applied to the second and
+ subsequent lines of a multi-line command.
+
+x. A fix was made to `disown' so that it does a better job of catching
+ out-of-range jobs.
+
+y. Non-interactive shells no longer report the status of processes terminated
+ due to SIGINT, even if the standard output is a terminal.
+
+z. A bug that caused the output of `jobs' to have extra carriage returns
+ was fixed.
+
+aa. A bug that caused PIPESTATUS to not be set when builtins or shell
+ functions were executed in the foreground was fixed.
+
+bb. Bash now attempts to detect when it is being run by sshd, and treats
+ that case identically to being run by rshd.
+
+cc. A bug that caused `set -a' to export SHELLOPTS when one of the shell
+ options was changed was fixed.
+
+dd. The `kill' builtin now disallows empty or missing process id arguments
+ instead of treating them as identical to `0', which means the current
+ process.
+
+ee. `var=value declare -x var' now behaves identically to
+ `var=value export var'. Similarly for `var=value declare -r var' and
+ `var=value readonly var'.
+
+ff. A few memory leaks were fixed.
+
+gg. `alias' and `unalias' now print error messages when passed an argument
+ that is not an alias for printing or deletion, even when the shell is
+ not interactive, as POSIX.2 specifies.
+
+hh. `alias' and `alias -p' now return a status of 0 when no aliases are
+ defined, as POSIX.2 specifes.
+
+ii. `cd -' now prints the pathname of the new working directory if the shell
+ is interactive.
+
+jj. A fix was made so that the code that binds $PWD now copes with getcwd()
+ returning NULL.
+
+kk. `unset' now checks whether or not a function name it's trying to unset
+ is a valid shell identifier only when the shell is running in posix mode.
+
+ll. A change was made to the code that generates filenames for here documents
+ to make them less prone to name collisions.
+
+mm. The parser was changed so that `time' is recognized as a reserved word
+ only at the beginning of a pipeline.
+
+nn. The pathname canonicalization code was changed so that `//' is converted
+ into `/', but all other pathnames beginning with `//' are left alone, as
+ POSIX.2 specifies.
+
+oo. The `logout' builtin will no longer exit a non-interactive non-login
+ shell.
+
+2. Changes to Readline
+
+a. Fixed a problem in the readline test program rltest.c that caused a core
+ dump.
+
+b. The code that handles parser directives in inputrc files now displays
+ more error messages.
+
+c. The history expansion code was fixed so that the appearance of the
+ history comment character at the beginning of a word inhibits history
+ expansion for that word and the rest of the input line.
+
+3. New Features in Bash
+
+a. A new version of malloc, based on the older GNU malloc, that has many
+ changes, is more page-based, is more conservative with memory usage,
+ and does not `orphan' large blocks when they are freed.
+
+b. A new version of gmalloc, based on the old GLIBC malloc, with many
+ changes and range checking included by default.
+
+c. A new implementation of fnmatch(3) that includes full POSIX.2 Basic
+ Regular Expression matching, including character classes, collating
+ symbols, equivalence classes, and support for case-insensitive pattern
+ matching.
+
+d. ksh-88 egrep-style extended pattern matching ([@+*?!](patlist)) has been
+ implemented, controlled by a new `shopt' option, `extglob'.
+
+e. There is a new ksh-like `[[' compound command, which implements
+ extended `test' functionality.
+
+f. There is a new `printf' builtin, implemented according to the POSIX.2
+ specification.
+
+g. There is a new feature for command substitution: $(< filename) now expands
+ to the contents of `filename', with any trailing newlines removed
+ (equivalent to $(cat filename)).
+
+h. There are new tilde prefixes which expand to directories from the
+ directory stack.
+
+i. There is a new `**' arithmetic operator to do exponentiation.
+
+j. There are new configuration options to control how bash is linked:
+ `--enable-profiling', to allow bash to be profiled with gprof, and
+ `--enable-static-link', to allow bash to be linked statically.
+
+k. There is a new configuration option, `--enable-cond-command', which
+ controls whether or not the `[[' command is included. It is on by
+ default.
+
+l. There is a new configuration option, `--enable-extended-glob', which
+ controls whether or not the ksh extended globbing feature is included.
+ It is enabled by default.
+
+m. There is a new configuration #define in config.h.top that, when enabled,
+ will cause all login shells to source /etc/profile and one of the user-
+ specific login shell startup files, whether or not the shell is
+ interactive.
+
+n. There is a new invocation option, `--dump-po-strings', to dump
+ a shell script's translatable strings ($"...") in GNU `po' format.
+
+o. There is a new `shopt' option, `nocaseglob', to enable case-insensitive
+ pattern matching when globbing filenames and using the `case' construct.
+
+p. There is a new `shopt' option, `huponexit', which, when enabled, causes
+ the shell to send SIGHUP to all jobs when an interactive login shell
+ exits.
+
+q. `bind' has a new `-u' option, which takes a readline function name as an
+ argument and unbinds all key sequences bound to that function in a
+ specified keymap.
+
+r. `disown' now has `-a' and `-r' options, to limit operation to all jobs
+ and running jobs, respectively.
+
+s. The `shopt' `-p' option now causes output to be displayed in a reusable
+ format.
+
+t. `test' has a new `-N' option, which returns true if the filename argument
+ has been modified since it was last accessed.
+
+u. `umask' now has a `-p' option to print output in a reusable format.
+
+v. A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...'
+ translation code. It expands to the character whose ascii code is NNN
+ in hexadecimal.
+
+w. The prompt string expansion code has a new `\r' escape sequence.
+
+x. The shell may now be cross-compiled for the CYGWIN32 environment on
+ a Unix machine.
+
+4. New Features in Readline
+
+a. There is now an option for `iterative' yank-last-arg handline, so a user
+ can keep entering `M-.', yanking the last argument of successive history
+ lines.
+
+b. New variable, `print-completions-horizontally', which causes completion
+ matches to be displayed across the screen (like `ls -x') rather than up
+ and down the screen (like `ls').
+
+c. New variable, `completion-ignore-case', which causes filename completion
+ and matching to be performed case-insensitively.
+
+d. There is a new bindable command, `magic-space', which causes history
+ expansion to be performed on the current readline buffer and a space to
+ be inserted into the result.
+
+e. There is a new bindable command, `menu-complete', which enables tcsh-like
+ menu completion (successive executions of menu-complete insert a single
+ completion match, cycling through the list of possible completions).
+
+f. There is a new bindable command, `paste-from-clipboard', for use on Win32
+ systems, to insert the text from the Win32 clipboard into the editing
+ buffer.
+
+g. The key sequence translation code now understands printf-style backslash
+ escape sequences, including \NNN octal escapes. These escape sequences
+ may be used in key sequence definitions or macro values.
+
+h. An `$include' inputrc file parser directive has been added.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01.1-release,
+and the previous version, bash-2.01-release.
+
+1. Changes to Bash
+
+a. The select command was fixed to check the validity of the user's
+ input more strenuously.
+
+b. A bug was fixed that prevented `time' from timing commands correctly
+ when supplied as an argument to `bash -c'.
+
+c. A fix was made to the mail checking code to keep from adding the same
+ mail file to the list of files to check multiple times when parsing
+ $MAILPATH.

+d. Fixed an off-by-one error in the tilde expansion library.
+
+e. When using the compound array assignment syntax, the old value of

+ to the default in the trap command associated with that signal.
+
+g. Fixed a bug in the locale code that occurred when assigning a value
+ to LC_ALL.
+
+h. A change was made to the parser so that words of the form xxx=(...)
+ are not considered compound assignment statements unless there are
+ characters before the `='.
+
+i. A fix was made to the command tracing code to correctly quote each
+ word of output.
+
+j. Some changes were made to the bash-specific autoconf tests to make them
+ more portable.

+
+n. Some fixes were made to make $RANDOM more random in subshells.
+
+o. System-specific changes were made to configure for: SVR4.2
+
+p. Changes were made so that completion of words containing globbing chars
+ substitutes the result only if a single filename was matched.
+
+q. The window size is now recomputed after a job is stopped with SIGTSTP if
+ the user has set `checkwinsize' with `shopt'.
+
+r. When doing substring expansion, out-of-range substring specifiers now
+ cause nothing to be substituted rather than an expansion error.
+
+s. A fix was made so that you can no longer trap `SIGEXIT' or `SIGDEBUG' --
+ only `EXIT' and `DEBUG' are accepted.
+
+t. The display of trapped signals now uses the signal number if signals
+ for which bash does not know the name are trapped.
+
+u. A fix was made so that `bash -r' does not turn on restricted mode until
+ after the startup files are executed.
+
+v. A bug was fixed that occasionally caused a core dump when a variable
+ found in the temporary environment of export/declare/readonly had a
+ null value.
+
+w. A bug that occasionally caused unallocated memory to be passed to free()
+ when doing arithmetic substitution was fixed.
+
+x. A bug that caused a buffer overrun when expanding a prompt string
+ containing `\w' and ${#PWD} exceeded PATH_MAX was fixed.
+
+y. A problem with the completion code that occasionally caused it to
+ refer to a character before the beginning of the readline line buffer
+ was fixed.
+
+z. A bug was fixed so that the `read' builtin restarts reads when
+ interrupted by signals other than SIGINT.
+
+aa. Fixed a bug that caused a command to be freed twice when there was
+ an evaluation error in the `eval' command.
+
+2. Changes to Readline
+
+a. Added a missing `extern' to a declaration in readline.h that kept
+ readline from compiling cleanly on some systems.
+
+b. The history file is now opened with mode 0600 when it is written for

+e. A bug that caused a core dump when the set of characters to be quoted
+ when completing words was empty was fixed.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-release,
+and the previous version, bash-2.01-beta2.
+
+1. Changes to Bash
+
+a. The `distclean' target should remove the `printenv' executable if it
+ has been created.
+
+b. The test suite was changed slightly to ensure that the error messages
+ are printed in English.
+
+c. A bug that caused the shell to dump core when a filename containing a
+ `/' was passed to `hash' was fixed.

+ requires.
+
+e. A memory leak when completing commands was fixed.
+
+f. A memory leak that occurred when checking the hash table for commands
+ with relative paths was fixed.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-beta2,
+and the previous version, bash-2.01-beta1.
+
+1. Changes to Bash
+
+a. The `ulimit' builtin translates RLIM_INFINITY to the hard limit only if
+ the current (soft) limit is less than or equal to the hard limit.
+
+b. Fixed a bug that caused the bash emulation of strcasecmp to produce
+ incorrect results.
+
+c. A bug that caused memory to be freed twice when a trap handler resets
+ the trap more than once was fixed.
+
+d. A bug that caused machines where sizeof (pointer) > sizeof (int) to
+ fail (and possibly dump core) when trying to unwind-protect a null
+ pointer was fixed.
+
+e. The startup files should not be run with job control enabled. This fix
+ allows SIGINT to once again interrupt startup file execution.
+
+f. Bash should not change the SIGPROF handler if it is set to something
+ other than SIG_DFL.
+
+g. The completion code that provides bash-specific completions for readline
+ now quotes characters that the readline code would treat as word break
+ characters if they appear in a file name.
+
+h. The completion code now correctly quotes filenames containing a `!',
+ even if the user attempted to use double quotes when attempting
+ completion.
+
+i. A bug that caused the shell to dump core when `disown' was called without
+ arguments and there was no current job was fixed.
+
+j. A construct like $((foo);bar) is now processed as a command substitution
+ rather than as a bad arithmetic substitution.
+
+k. A couple of bugs that caused `fc' to not obey the `cmdhist' and `lithist'
+ shell options when editing and re-executing a series of commands were
+ fixed.
+
+l. A fix was made to the grammar -- the list of commands between `do' and
+ `done' in the body of a `for' command should be treated the same as a
+ while loop.
+
+2. Changes to Readline
+
+a. A couple of bugs that caused the history search functions to attempt to
+ free a NULL pointer were fixed.
+
+b. If the C library provides setlocale(3), readline does not need to look
+ at various environment variables to decide whether or not to go into
+ eight-bit mode automatically -- just check whether the current locale
+ is not `C' or `POSIX'.
+
+c. If the filename completion function finds that a directory was not closed
+ by a previous (interrupted) completion, it closes the directory with
+ closedir().
+
+3. New Features in Bash
+
+a. New bindable readline commands: history-and-alias-expand-line and
+ alias-expand-line. The code was always in there, there was just no
+ way to execute it.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-beta1,
+and the previous version, bash-2.01-alpha1.

+
+c. ${GROUPS[0]} should always be the primary group, even on systems without
+ multiple groups.
+

+ here document cannot be created.
+
+i. Many changes to the shell's variable initialization code to speed
+ non-interactive startup.
+
+j. Changes to the non-job-control code so that it does not try to open
+ /dev/tty.
+
+k. The output of `set' and `export' is once again sorted, as POSIX wants.
+
+l. Fixed a problem caused by a recursive call reparsing the value of
+ $SHELLOPTS.
+
+m. The tilde code no longer calls getenv() when it's compiled as part of
+ the shell, which should eliminate problems on systems that cannot
+ redefine getenv(), like the NeXT OS.
+
+n. Fixed a problem that caused `bash -o' or `bash +o' to not list all
+ the shell options.
+
+o. Fixed `ulimit' to convert RLIM_INFINITY to the appropriate hard limit
+ only if the hard limit is greater than the current (soft) limit.
+
+p. Fixed a problem that arose when building bash in a different directory
+ than the source and y.tab.[ch] were remade with something other than
+ bison. This came up most often on NetBSD.
+
+q. Fixed a problem with completion -- it thought that `pwd`/[TAB] indicated
+ an unfinished command completion (`/), which generated errors.
+
+r. The bash special tilde expansions (~-, ~+) are now attempted before
+ calling the standard tilde expansion code, which should eliminate the
+ problems people have been seeing with this on Solaris 2.5.1.
+
+s. Added support for <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.
+
+u. A number of changes to speed up export environment creation were made.
+
+v. A number of memory leaks were fixed as the result of running the test
+ scripts through Purify.
+
+w. Fixed a bug that caused subshells forked to interpret executable
+ scripts without a leading `#!' to not reinitialize the values of
+ the shell options.
+
+2. Changes to Readline
+
+a. History library has less `#ifdef SHELL' code -- abstracted stuff out
+ into application-specific function hooks.
+
+b. Readline no longer calls getenv() if it's compiled as part of the shell,
+ which should eliminate problems on systems that cannot redefine getenv(),
+ like the NeXT OS.
+
+c. Fixed translation of ESC when `untranslating' macro values.
+
+d. The region kill operation now fixes the mark if it ends up beyond the
+ boundaries of the line after the region is deleted.
+
+3. New Features in Bash
+
+a. New argument for `configure': `--with-curses'. This can be used to
+ override the selection of the termcap library on systems where it is
+ deficient.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-alpha1,
+and the previous version, bash-2.0-release.

+ the command could not be found was fixed.
+
+d. The code that performs output redirections is now more resistant to
+ race conditions and possible security exploits.
+
+e. A bug that caused the shell to dump core when performing pattern
+ substitutions on variable values was fixed.
+
+f. More hosts are now recognized by the auto-configuration mechanism
+ (OpenBSD, QNX, others).
+
+g. Assignments to read-only variables that attempt to convert them to
+ arrays are now errors.
+
+h. A bug that caused shell scripts using array assignments in POSIX mode
+ to exit after the assignment was performed was fixed.

+i. The substring expansion code is now more careful about running off the
+ ends of the expanded variable value.
+
+j. A bug that caused completion to fail if a backquoted command substitution
+ appeared anywhere on the line was fixed.
+
+k. The `source' builtin no longer turns off history if it has been enabled
+ in a non-interactive shell.
+
+l. A bug that caused the shell to crash when `disown' was given a pid
+ instead of a job number was fixed.
+
+m. The `cd' spelling correction code will not try to change to `.' if no
+ directory entries match a single-character argument.
+
+n. A bad variable name supplied to `declare', `export', or `readonly' no
+ longer causes a non-interactive shell in POSIX mode to exit.
+
+o. Some fixes were made to the test suite to handle peculiarities of
+ various Unix versions.
+
+p. The bash completion code now quotes characters that readline would
+ treat as word breaks for completion but are not shell metacharacters.
+
+q. Bad options supplied at invocation now cause a usage message to be
+ displayed.
+
+r. Fixes were made to the code that handles DEBUG traps so that the trap
+ string is not freed inappropriately.
+
+s. Some changes were made to the bash debugger in examples/bashdb -- it
+ should be closer to working now.
+
+t. A problem that caused the default filename used for mail checking to be
+ wrong was fixed.
+
+u. A fix was made to the `echo' builtin so that NUL characters printed with
+ `echo -e' do not cause the output to be truncated.
+
+v. A fix was made to the job control code so that the shell behaves better
+ when monitor mode is enabled in a non-interactive shell.
+
+w. Bash no longer catches all of the terminating signals in a non-
+ interactive shell until a trap is set on EXIT, which should result in
+ quicker startup.
+
+x. A fix was made to the command timing code so that `time' can be used in
+ a loop.
+
+y. A fix was made to the parser so that `((cmd); cmd2)' is now parsed as
+ a nested subshell rather than strictly as an (erroneous) arithmetic
+ command.
+
+z. A fix was made to the globbing code so that it correctly matches quoted
+ filenames beginning with a `.'.
+
+aa. A bug in `fc' that caused some multi-line commands to not be stored as
+ one command in the history when they were re-executed after editing
+ (with `fc -e') was fixed.
+
+bb. The `ulimit' builtin now attempts to catch some classes of integer
+ overflows.
+
+cc. 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
+ was fixed.
+
+ee. A bug that caused the shell to crash when an unset variable appeared
+ in the body of a here document after `set -u' had been executed was
+ fixed.
+
+ff. Implicit input redirections from /dev/null for asynchronous commands
+ are now handled better.
+
+gg. A bug that caused the shell to fail to compile when configured with
+ `--disable-readline' was fixed.
+
+hh. The globbing code should now be interruptible.
+
+ii. Bash now notices when the `kill' builtin is used to send SIGCONT to a
+ stopped job and adjusts the data structures accordingly, as if `bg' had
+ been executed instead.
+
+jj. A bug that caused the shell to crash when mixing calls to `getopts'
+ and `shift' on the same set of positional parameters was fixed.
+
+kk. The command printing code now preserves the `-p' flag to `time'.
+
+ll. The command printing code now handles here documents better when there
+ are other redirections associated with the command.
+
+mm. The special glibc environment variable (NNN_GNU_nonoption_argv_flags_)
+ is no longer placed into the environment of executed commands -- users
+ of glibc had too many problems with it.
+
+nn. Reorganized the code that generates signames.h. The signal_names list
+ is now more complete but may be slightly different (SIGABRT is favored
+ over SIGIOT, for example). The preferred signal names are those
+ listed in the POSIX.2 standard.
+
+oo. `bashbug' now uses a filename shorter than 14 characters for its
+ temporary file, and asks for confirmation before sending the bug
+ report.
+
+pp. A bug that caused TAB completion in vi editing mode to not be turned
+ off when `set -o posix' was executed or back on when `set +o posix'
+ was executed was fixed.
+
+qq. A bug in the brace expansion code that caused brace expansions appearing
+ in new-style $(...) command substitutions to be inappropriately expanded
+ was fixed.
+
+rr. A bug in the readline hook shell-expand-line that could cause memory to
+ be inappropriately freed was fixed.
+
+ss. A bug that caused some arithmetic expressions containing `&&' and `||'
+ to be parsed with the wrong precedence has been fixed.
+
+tt. References to unbound variables after `set -u' has been executed now
+ cause the shell to exit immediately, as they should.
+
+uu. A bug that caused the shell to exit inappropriately when `set -e' had
+ been executed and a command's return status was being inverted with the
+ `!' reserved word was fixed.
+
+vv. A bug that could occasionally cause the shell to crash with a
+ divide-by-zero error when timing a command was fixed.
+
+ww. A bug that caused parameter pattern substitution to leave stray
+ backslashes in the replacement string when the expression is in
+ double quotes was fixed.
+
+xx. The `break' and `continue' builtins now break out of all loops when an
+ invalid count argument is supplied.
+
+yy. Fixed a bug that caused PATH to be set to the empty string if
+ `command -p' is executed with PATH unset.
+
+zz. Fixed `kill -l signum' to print the signal name without the `SIG' prefix,
+ as POSIX specifies.
+
+aaa. Fixed a bug that caused the shell to crash while setting $SHELLOPTS
+ if there were no shell options set.
+
+bbb. Fixed `export -p' and `readonly -p' so that when the shell is in POSIX
+ mode, their output is as POSIX.2 specifies.
+
+ccc. Fixed a bug in `readonly' so that `readonly -a avar=(...)' actually
+ creates an array variable.
+
+ddd. Fixed a bug that prevented `time' from correctly timing background
+ pipelines.
+
+2. 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.
--- /dev/null
+This document details the changes between this version, bash-4.3-alpha,
+and the previous version, bash-4.2-release.
+
+1. Changes to Bash
+
+a. Fixed several bugs concerning incomplete bracket expressions in filename
+ generation (globbing) patterns.
+
+b. Fixed a bug with single quotes and WORD in ${param op WORD} when running
+ in Posix mode.
+
+c. Fixed a bug that caused the pattern removal and pattern substitution word
+ expansions and case statement word expansion to not match the empty string.
+
+d. Fixed a bug that caused the tzset() function to not work after changing
+ the TZ enviroment variable.
+
+e. Fixed a bug that caused the RHS of an assignment statement to undergo
+ word splitting when it contained an unquoted $@.
+
+f. Fixed bugs that caused the shell to not react to a SIGINT sent while
+ waiting for a child process to exit.
+
+g. Bash doesn't try to run things in a signal handler context when it gets a
+ signal (SIGINT/SIGHUP/etc) while reading input using readline but still
+ be responsive to terminating signals.
+
+h. Fixed a bug that caused bash to go into an infinite loop if a filename
+ to be matched contained an invalid multibyte character.
+
+i. Fixed a bug that caused PS4 to end up being truncated if it is longer
+ than 128 bytes.
+
+j. Fixed a bug that caused brace expansion to not skip over double-quoted
+ command substitution.
+
+k. System-specific updates for: DJGPP, HP/UX, Mac OS X
+
+l. Fixed a bug in displaying commands that caused redirections to be associated
+ with the wrong part of the command.
+
+m. Fixed the coproc cleanup to unset the appropriate shell variables when a
+ coproc terminates.
+
+n. Fixed a bug that caused `fc' to dump core due to incorrect calculation of
+ the last history entry.
+
+o. Added workarounds for FreeBSD's implementation of faccessat/eaccess and
+ `test -x'.
+
+p. Fixed a bug that caused the shell to not match patterns containing
+ control-A.
+
+q. Fixed a bug that could result in doubled error messages when the `printf'
+ builtin got a write error.
+
+r. Fixed a bug that caused the shell to not correctly expand words containing
+ multiple consecutive quoted empty strings (""""""aa).
+
+s. Fixed a bug that caused the shell to not correctly parse multi-line
+ process substitutions containing comments and quoted strings.
+
+t. Fixed a problem with the bash malloc's internal idea of the top of the
+ memory heap that resulted in incorrect decisions to try to reduce the
+ break and give memory back to the kernel.
+
+u. There are changes to the expansions peformed on compound array assignments,
+ in an effort to make foo=( [ind1]=bar [ind2]=baz ) identical to
+ foo[ind1]=bar foo[ind2]=baz.
+
+v. Bash now reports an error if `read -a name' is used when `name' is an
+ existing associative array.
+
+w. Fixed a bug that allowed an attempted assignment to a readonly variable
+ in an arithmetic expression to not return failure.
+
+x. Fixed several bugs that caused completion functions to be invoked even when
+ the cursor was before the first word in the command.
+
+y. Fixed a bug that caused parsing a command substitution to overwrite the
+ parsing state associated with the complete input line.
+
+z. Fixed several bugs with the built-in snprintf replacement and field widths
+ and floating point.
+
+aa. Fixed a bug that caused incorrect offset calculations and input buffer
+ corruption when reading files longer than 2^31 bytes.
+
+bb. Fixed several bugs where bash performed arithmetic evaluation in contexts
+ where evaluation is suppressed.
+
+cc. Fixed a bug that caused bash to close FIFOs used for process substitution
+ too early when a shell function was executing, but protect against using
+ all file descriptors when the shell functions are invoked inside loops.
+
+dd. Added checks for printable (and non-printable) multibyte characters for
+ use in error messages.
+
+ee. Fixed a bug that caused ^O (operate-and-get-next) to not work correctly
+ at the end of the history list.
+
+ff. Fixed a bug that caused command-oriented history to incorrectly combine
+ here documents into one line.
+
+gg. Fixed a bug that caused importing SHELLOPTS from the environment into a
+ Posix-mode shell to print an error message and refuse to parse it.
+
+hh. Fixed a bug that caused the shell to delete an extra history entry when
+ using `history -s'.
+
+ii. Fixed a bug that caused floating-point exceptions and overflow errors
+ for the / and % arithmetic operators when using INTMAX_MIN and -1.
+
+jj. Fixed a bug that caused parsing errors when reading an arithmetic for
+ loop inside a command substitution.

+
+mm. Fixed a bug that caused redirections to fail because the file descriptor
+ limit was set to a value less than 10.
+
+nn. Fixed a bug that caused the `read' builtin to execute code in a signal
+ handler context if read timed out.
+
+oo. Fixed a bug that caused extended globbing patterns to not match files
+ beginning with `.' correctly when a `.' was explicitly supplied in the
+ pattern.
+
+pp. Fixed a bug that caused key sequences longer than two characters to not
+ work when used with `bind -x'.
+
+qq. Fixed a bug that resulted in redefined functions having the wrong source
+ file names in BASH_SOURCE.
+
+rr. Fixed a bug that caused the read builtin to assign null strings to variables

+
+xx. Fixed several bugs with the handling of valid and invalid unicode character
+ values when used with the \u and \U escape sequences to printf and $'...'.
+
+yy. Fixed a bug that caused tildes to not be escaped in expanded filenames,
+ making them subject to later expansion.
+
+zz. When using the pattern substitution word expansion, bash now runs the
+ replacement string through quote removal, since it allows quotes in that
+ string to act as escape characters. This is not backwards compatible, so
+ it can be disabled by setting the bash compatibility mode to 4.2.
+
+aaa. Fixed the rest of the cases where the shell runs non-allowed code in a
+ signal handler context.
+
+bbb. Fixed a bug that caused spurious DEL characters (\177) to appear in

+
+ccc. Fixed a bug that caused the use of the shell's internal random number

+ddd. Fixed several bugs that caused `declare -g' to not set the right global
+ variables or to misbehave when declaring global indexed arrays.
+
+eee. Fixed a logic bug that caused extended globbing in a multibyte locale to
+ cause failures when using the pattern substititution word expansions.
+
+fff. Fixed a bug that caused the `lastpipe' option to corrupt the file
+ descriptor used to read the script.
+
+ggg. Fixed a bug that causes the shell to delete DEL characters in the
+ expanded value of variables used in the same quoted string as variables
+ that expand to nothing.
+
+hhh. Fixed a bug that caused the shell to assign the wrong value from an
+ assignment like (( x=7 )) when `x' was an existing array variable.
+
+iii. Fixed a bug that caused the shell to misbehave when generating sequences
+ and the boundary values overflow an intmax_t.
+
+jjj. Fixed a bug caused expansion errors if an expansion of "$@" appeared
+ next to another expansion (e.g.. "${@}${x}").
+

+
+lll. Fixed a bug that resulted in an extra semicolon being added to compound

+
+rrr. Fixed a bug that resulted in the shell returning the wrong exit status

+ttt. Fixed a bug that caused `eval "... ; return"' to not clean up properly.
+
+uuu. Fixed a bug that caused the shell to dump core if `read' reads an escaped
+ IFS whitespace character.
+
+vvv. Fixed a bug that caused BASH_COMMAND to be set to an incorrect value when
+ executing a (...) subshell.
+
+www. Fixed a couple of pointer aliasing bugs with the token string in arithmetic
+ evaluation.
+
+xxx. Fixed a bug with parsing multi-line command substitutions when reading
+ the `do' keyword followed by whitespace.
+
+yyy. Fixed a bug that caused the shell to seg fault if the time given to the
+ printf %(...)T format overflowed the value accepted by localtime(3).
+
+zzz. Fixed a problem with displaying help topics in two columns when the
+ translated text contained multibyte characters.
+
+aaaa. Fixed a bug with the extended globbing pattern matcher where a `*' was
+ followed by a negated extended glob pattern.
+
+bbbb. Fixed a race condition with short-lived coproc creation and reaping that
+ caused the child process to be reaped before the various coproc shell
+ variables were initialized.
+
+cccc. Fixed a bug where turning off `errexit' in command substitution subshells
+ was not reflected in $SHELLOPTS.
+
+dddd. Partially fixed an inconsistency in how the shell treated shell
+ functions run from an EXIT trap.
+
+eeee. Fixed a bug in how the shell invalidated FIFOs used for process
+ substitution when executing a pipeline (once rather than in every child).
+
+ffff. Fixed a bug that occurred when expanding a special variable ($@, $*)
+ within double quotes and the expansion resulted in an empty string.
+
+gggg. Fixed bugs with executing a SIGCHLD trap handler to make sure that it's
+ executed once per exited child.
+
+hhhh. Fixed a bug that caused `declare' and `test' to find variables that
+ had been given attributes but not assigned values. Such variables are
+ not set.
+
+iiii. Fixed a bug that caused commands in process substitutions to not look in
+ the local temporary environment when performing word expansions.
+
+jjjj. Fixed several problems with globstar expansions (**/**) returning null
+ filenames and multiple instances of the same pathname.
+
+kkkk. Fixed an oversight that did not allow the exit status of `coproc' to
+ be inverted using `!'.
+
+llll. Fixed a bug that caused the -e option to be re-enabled using `set -e'
+ even when executing in a context where -e is ignored.
+
+mmmm. Fixed a (mostly theoretical) bug with input lines longer than SIZE_MAX.
+
+nnnn. Fixed a bug that could result in double evaluation of command
+ substitutions when they appear in failed redirections.
+
+oooo. Fixed a bug that could cause seg faults during `mapfile' callbacks if
+ the callback unsets the array variable mapfile is using.
+
+pppp. Fixed several problems with variable assignments using ${var:=value}
+ when the variable assignment is supposed to have side effects.
+
+qqqq. Fixed a bug that caused a failure of an assignment statement preceding a
+ builtin caused the next invocation of a special builtin to exit the shell.
+
+rrrr. Fixed several problems with IFS when it appears in the temporary environment
+ and is used in redirections.
+
+ssss. Fixed a problem that caused IFS changes using ${IFS:=value} to modify

+
+tttt. Fixed a problem that caused subshells to not run an EXIT trap they set.
+
+uuuu. Fixed a problem that caused shells started in posix mode to attempt to
+ import shell functions with invalid names from the environment. We now

+ interactive shells when it arrived before the child process reset the
+ handler from SIG_DFL.
+
+bbbbb. Fixed a bug that caused redirections like <&n- to leave file descriptor
+ n closed if executed with a builtin command.
+
+ccccc. Fixed a bug that caused incorrect completion quoting when completing a
+ word containing a globbing character with `show-all-if-ambiguous' set.
+
+ddddd. Fixed a bug that caused printf's %q format specifier not to quote a
+ tilde even if it appeared in a location where it would be subject to
+ tilde expansion.
+
+2. Changes to Readline
+
+a. Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode
+ commands to work on the entire line.
+
+b. Fixed a bug that caused redisplay problems with prompts longer than 128
+ characters and history searches.
+
+c. Fixed a bug that caused readline to try and run code to modify its idea
+ of the screen size in a signal handler context upon receiving a SIGWINCH.
+
+d. Fixed a bug that caused the `meta' key to be enabled beyond the duration
+ of an individual call top readline().
+
+e. Added a workaround for a wcwidth bug in Mac OS X that caused readline's
+ redisplay to mishandle zero-width combining characters.
+
+f. Fixed a bug that caused readline to `forget' part of a key sequence when
+ a multiple-key sequence caused it to break out of an incremental search.
+
+g. Fixed bugs that caused readline to execute code in a signal handler
+ context if interrupted while reading from the file system during completion.

+
+i. Fixed a bug that caused Readline's signal handlers to be installed beyond
+ the bounds of a single call to readline().
+
+j. Fixed a bug that caused the `.' command to not redo the most recent `R'
+ command in vi mode.
+
+k. Fixed a bug that caused ignoring case in completion matches to result in
+ readline using the wrong match.
+
+l. Paren matching now works in vi insert mode.
+
+m. Fix menu-completion to make show-all-if-ambiguous and menu-complete-display-prefix
+ work together.
+

+ in vi editing mode.
+
+o. Fixed a bug that caused the filename comparison code to not compare
+ multibyte characters correctly when using case-sensitive or case-mapping
+ comparisons.
+
+p. Fixed the input reading loop to call the input hook function only when there
+ is no terminal input available.
+
+q. Fixed a bug that caused binding a macro to a multi-character key sequence
+ where the sequence and macro value share a common prefix to not perform
+ the macro replacement.
+
+r. Fixed several redisplay errors with multibyte characters and prompts
+ containing invisible characters when using horizontal scrolling.
+
+s. Fixed a bug that caused redisplay errors when trying to overwrite
+ existing characters using multibyte characters.
+
+3. New Features in Bash
+
+a. The `helptopic' completion action now maps to all the help topics, not just
+ the shell builtins.
+
+b. The `help' builtin no longer does prefix substring matching, so `help read'
+ does not match `readonly'.
+
+c. The shell can be compiled to not display a message about processes that
+ terminate due to SIGTERM.
+
+d. Non-interactive shells now react to the setting of checkwinsize and set
+ LINES and COLUMNS after a foreground job exits.
+
+e. There is a new shell option, `globasciiranges', which, when set to on,
+ forces globbing range comparisons to use character ordering as if they
+ were run in the C locale.
+
+f. There is a new shell option, `direxpand', which makes filename completion
+ expand variables in directory names in the way bash-4.1 did.
+
+g. In Posix mode, the `command' builtin does not change whether or not a
+ builtin it shadows is treated as an assignment builtin.
+
+h. The `return' and `exit' builtins accept negative exit status arguments.
+
+i. The word completion code checks whether or not a filename containing a
+ shell variable expands to a directory name and appends `/' to the word
+ as appropriate. The same code expands shell variables in command names
+ when performing command completion.
+
+j. In Posix mode, it is now an error to attempt to define a shell function
+ with the same name as a Posix special builtin.
+
+k. When compiled for strict Posix conformance, history expansion is disabled
+ by default.
+
+l. The history expansion character (!) does not cause history expansion when
+ followed by the closing quote in a double-quoted string.
+
+m. `complete' and its siblings compgen/compopt now takes a new `-o noquote'
+ option to inhibit quoting of the completions.
+
+n. Setting HISTSIZE to a value less than zero causes the history list to be
+ unlimited (setting it 0 zero disables the history list).
+
+o. Setting HISTFILESIZE to a value less than zero causes the history file size
+ to be unlimited (setting it to 0 causes the history file to be truncated
+ to zero size).
+
+p. The `read' builtin now skips NUL bytes in the input.
+
+q. There is a new `bind -X' option to print all key sequences bound to Unix
+ commands.
+
+r. When in Posix mode, `read' is interruptible by a trapped signal. After
+ running the trap handler, read returns 128+signal and throws away any
+ partially-read input.
+
+s. The command completion code skips whitespace and assignment statements
+ before looking for the command name word to be completed.
+
+t. The build process has a new mechanism for constructing separate help files
+ that better reflects the current set of compilation options.
+
+u. The -nt and -ot options to test now work with files with nanosecond
+ timestamp resolution.
+
+v. The shell saves the command history in any shell for which history is
+ enabled and HISTFILE is set, not just interactive shells.
+
+w. The shell has `nameref' variables and new -n(/+n) options to declare and
+ unset to use them, and a `test -R' option to test for them.
+
+x. The shell now allows assigning, referencing, and unsetting elements of
+ indexed arrays using negative subscripts (a[-1]=2, echo ${a[-1]}) which
+ count back from the last element of the array.
+
+y. The {x}<word redirection feature now allows words like {array[ind]} and
+ can use variables with special meanings to the shell (e.g., BASH_XTRACEFD).
+
+z. There is a new CHILD_MAX special shell variable; its value controls the
+ number of exited child statues the shell remembers.
+
+aa. There is a new configuration option (--enable-direxpand-default) that
+ causes the `direxpand' shell option to be enabled by default.
+
+bb. Bash does not do anything special to ensure that the file descriptor
+ assigned to X in {x}<foo remains open after the block containing it
+ completes.
+
+cc. The `wait' builtin has a new `-n' option to wait for the next child to
+ change status.
+
+dd. The `printf' %(...)T format specifier now uses the current time if no
+ argument is supplied.
+
+ee. There is a new variable, BASH_COMPAT, that controls the current shell
+ compatibility level.
+
+ff. The `popd' builtin now treats additional arguments as errors.
+
+gg. The brace expansion code now treats a failed sequence expansion as a
+ simple string and will continue to expand brace terms in the remainder
+ of the word.
+
+4. New Features in Readline
+
+a. Readline is now more responsive to SIGHUP and other fatal signals when
+ reading input from the terminal or performing word completion but no
+ longer attempts to run any not-allowable functions from a signal handler
+ context.
+
+b. There are new bindable commands to search the history for the string of
+ characters between the beginning of the line and the point
+ (history-substring-search-forward, history-substring-search-backward)
+
+c. Readline allows quoted strings as the values of variables when setting
+ them with `set'. As a side effect, trailing spaces and tabs are ignored
+ when setting a string variable's value.
+
+d. The history library creates a backup of the history file when writing it
+ and restores the backup on a write error.
+
+e. New application-settable variable: rl_filename_stat_hook: a function called
+ with a filename before using it in a call to stat(2). Bash uses it to
+ expand shell variables so things like $HOME/Downloads have a slash
+ appended.
+
+f. New bindable function `print-last-kbd-macro', prints the most-recently-
+ defined keyboard macro in a reusable format.
+
+g. New user-settable variable `colored-stats', enables use of colored text
+ to denote file types when displaying possible completions (colored analog
+ of visible-stats).
+
+h. New user-settable variable `keyseq-timout', acts as an inter-character
+ timeout when reading input or incremental search strings.
+
+i. New application-callable function: rl_clear_history. Clears the history list
+ and frees all readline-associated private data.
+
+j. New user-settable variable, show-mode-in-prompt, adds a characters to the
+ beginning of the prompt indicating the current editing mode.
+
+k. New application-settable variable: rl_input_available_hook; function to be
+ called when readline detects there is data available on its input file
+ descriptor.
+
+l. Readline calls an application-set event hook (rl_signal_event_hook) after
+ it gets a signal while reading input (read returns -1/EINTR but readline
+ does not handle the signal immediately) to allow the application to handle
+ or otherwise note it. Not currently called for SIGHUP or SIGTERM.
+
+m. If the user-settable variable `history-size' is set to a value less than
+ 0, the history list size is unlimited.

+
+h. Fixed the cd and pwd builtins to return failure if PWD is readonly and
+ cannot be assigned to.
+
+i. Added code to check the return value of access(2) on Solaris systems,

+
+f. Fixed a bug that caused variable expansions preceding regular builtins to
+ not change the shell environment during their execution.
+
+2. Changes to Readline
+

+ as if it were a negative argument.
+
+------------------------------------------------------------------------------
+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

+
+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'

+ 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.

+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 and 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.
+

+ mail in a `maildir' environment.
+
+j. Fixed a bug that caused the shell to not recognize a here-document ending
+ delimiter inside a command substitution.
+
+k. Fixed a bug that caused the shell to crash when a a dynamic array variable
+ was assigned a scalar value.
+
+2. Changes to Readline
+
+3. New Features in Bash
+
+a. The mapfile/readarray builtin no longer stores the commands it invokes via
+ callbacks in the history list.
+
+b. There is a new `compat40' shopt option.
+
+c. The < and > operators to [[ do string comparisons using the current locale
+ only if the compatibility level is greater than 40 (set to 41 by default).
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.1-alpha,
+and the previous version, bash-4.0-release.
+
+1. Changes to Bash
+
+a. Fixed bugs in the parser involving new parsing of the commands contained
+ in command substitution when the substitution is read.
+
+b. Fixed a bug that caused the shell to dump core when performing programmable
+ completion using a shell function.
+
+c. Fixed a bug in `mapfile' that caused it to invoke callbacks at the wrong
+ time.
+
+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
+ the `fc' builtin.
+
+r. Fixed a bug that caused some terminating signals to not exit the shell
+ quickly enough, forcing the kernel to send the signal (e.g., SIGSEGV)
+ 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.
+
+bb. Fixed a bug that caused brace expansion to take place too soon in some
+ compound array assignments.
+
+cc. Fixed a bug that caused programmable completion functions' changes to
+ READLINE_POINT to not be reflected back to readline.

+gg. Fixed a bug that caused the ERR trap to be triggered in some cases where
+ `set -e' would not have caused the shell to exit.
+
+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.
+
+u. The read builtin has a new `-N nchars' option, which reads exactly NCHARS
+ 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.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.0-release,
+and the previous version, bash-4.0-rc1.
+
+1. Changes to Bash
+
+a. Changed the message printed when setlocale(3) fails to only include the
+ strerror error text if the call changes errno.
+
+b. Changed trap command execution to reset the line number before running a
+ trap (except DEBUG and RETURN traps).
+
+c. Fixed behavior of case-modifiying word expansions to not work on
+ individual words within a variable's value.
+
+d. Fixed a bug that caused mapfile to not be interruptible when run in an
+ interactive shell.
+
+e. Fixed a bug that caused mapfile to not run callbacks for the first line
+ read.
+
+f. Fixed a bug that caused mapfile to not honor EOF typed in an interactive
+ shell.
+
+g. Fixed the coprocess reaping code to not run straight from a signal handler.
+
+h. Fixed a bug that caused printf -b to ignore the first % conversion specifier
+ in the format string on 64-bit systems.
+
+i. Fixed a bug that caused incorrect word splitting when `:', `=', or `~'
+ appeared in $IFS.
+
+j. Fixed a bug that caused data corruption in the programmable completion code
+ when a shell function called from a completion aborted execution.
+
+k. Fixed a bug that caused the CPU usage reported by the `time' builtin to be
+ capped at 100%.
+
+l. Changed behavior of shell when -e option is in effect to reflect consensus
+ of Posix shell standardization working group.
+
+m. Fixed a bug introduced in bash-4.0-alpha that caused redirections to not
+ be displayed by `type' or `declare' when appearing in functions under
+ certain circumstances.
+
+2. Changes to Readline
+
+a. Fixed a bug that caused !(...) extended glob patterns to inhibit later
+ history expansion.

+
+e. Fixed a bug that resulted in bash not terminating immediately if a
+ terminating signal was received while performing output.
+
+f. Fixed a bug that caused the shell to crash after creating 256 process

+a. Fixed a typo that caused a variable to be used before initialization
+ while parsing Posix-style command substitutions.
+
+b. Fixed a bug that caused stray ^? when the expansion of a parameter used
+ as part of a pattern removal expansion is empty, but part of a non-

+
+c. Fixed a bug that could cause strings not converted to numbers by strtol

+
+f. Changed behavior so the shell now acts as if it received an interrupt
+ when a pipeline is killed by SIGINT while executing a list.

+
+h. Changed `bind' builtin to print a warning but proceed if invoked when

+n. Fixed a bug that could cause memory to be freed multiple times when
+ assigning to COMP_WORDBREAKS.
+
+o. Fixed a bug that could cause NULL pointer dereferences when COMP_WORDBREAKS
+ was unset.
+
+2. Changes to Readline
+
+3. New Features in Bash
+

+ input available to be read from the specified file descriptor.
+
+b. CDPATH and GLOBIGNORE are ignored when the shell is running in privileged
+ mode.
+
+c. New bindable readline functions shell-forward-word and shell-backward-word,
+ which move forward and backward words delimited by shell metacharacters
+ and honor shell quoting.
+
+d. New bindable readline functions shell-backward-kill-word and shell-kill-word
+ which kill words backward and forward, but use the same word boundaries
+ as shell-forward-word and shell-backward-word.
+
+4. New Features in Readline
+
+a. If the kernel supports it, readline displays special characters
+ corresponding to a keyboard-generated signal when the signal is received.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-4.0-alpha,
+and the previous version, bash-3.2-release.
+
+1. Changes to Bash
+
+a. Fixed several bugs in old-style `` command substitution parsing, including
+ comment parsing and quoted string handling.
+
+b. Fixed problems parsing arguments to the [[ command's =~ regular expression
+ matching operator: metacharacter and whitespace parsing.
+
+c. Fixed a bug that caused the shell to inappropriately reuse high-numbered
+ file descriptors it used internally.
+
+d. Fixed a bug in pattern replacement word expansions that caused a `/' as
+ the first character of an expanded pattern to be mistaken for a global
+ replacement specifier.
+
+e. Fixed several problems with the asprintf and snprintf replacement functions
+ that caused hangs and crashes.
+
+f. Fixed a bug in the calculation of the current and previous job that caused
+ it to refer to incorrect jobs.

+ caused unnecessary hash table deletions and additions.
+
+h. Fixed a bug that caused child processes to inherit the wrong value for $!.
+
+i. Fixed a bug that caused `.' to fail to read and execute commands from non-

+
+p. Fixed several problems with pattern substitution expansions on the
+ positional parameters and arrays subscripted with * or @ that occurred
+ when $IFS was set to the empty string.
+
+q. Made a change to the default locale initialization code that should
+ result in better behavior from the locale-aware library functions.
+

+
+z. Fixed bugs caused by shell builtins not checking for all write errors.
+
+aa. Fixed a problem that caused the shell to dump core if expansions on the
+ pattern passed to the pattern removal word expansions resulted in expansion
+ errors.
+
+bb. Fixed a bug that caused bash to loop infinitely after creating and
+ waiting for 4096 jobs.
+
+cc. Fixed a bug that caused bash to lose the status of a background job under
+ certain circumstances.
+
+dd. Fixed a bug that caused bash to not look in the temporary environment
+ when performing variable lookup under certain circumstances.
+
+ee. Fixed a bug that caused bash to close file descriptors greater than 10
+ when they were used in redirections.
+
+ff. Fixed a problem that caused the shell to attempt to read from the standard
+ input when called as `bash -i script'.
+
+gg. Fixed a memory leak and variable initialization problems when the -v option
+ was supplied to `printf' that could cause incorrect results.
+
+hh. Fixed a bug that caused the `read' builtin to count bytes when the -n option
+ was supplied, rather than (possibly multibyte) characters.
+
+ii. Fixed a bug when displaying a function due to not converting the function
+ to an external form.
+
+jj. Changed job control initialization to ensure that the shell has a tty

+kk. Fixed a bug with the `test' builtin that caused it to misinterpret
+ arguments beginning with `-' but containing more than one character.
+
+ll. Fixed bug that could cause the shell to dump core in certain cases where
+ a command sets the SIGINT disposition to the default.
+
+mm. Fixed a bug in the pattern replacement (affecting both word expansion
+ and the `fc' builtin) that occurred when the pattern and replacement
+ strings were empty.
+
+nn. Fixed a bug that caused an arithmetic evaluation error to disable all
+ further evaluation.
+
+oo. Fixed a bug in pathname expansion that caused it to interpret backslashes
+ in the pathname as quoting characters.
+
+pp. Fixed a bug in the replacement getcwd() implementation that could cause
+ memory to be overwritten.
+
+qq. When in Posix mode, the `ulimit' builtin now uses a block size of 512 for
+ the `-c' and `-f' options.
+
+rr. Brace expansion now allows process substitutions to pass through unchanged.
+
+ss. Fixed a problem in the command name completion code to avoid quoting
+ escaped special characters twice when the command name begins with a tilde.
+
+tt. Fixed a problem in the printf builtin that resulted in single-byte
+ output for the "'" escape, even when using multibyte characters.
+
+uu. Fixed a bug that caused the failure exit status to be lost when redirections
+ attached to a compound command failed.
+
+vv. Fixed a bug that caused the internal random number generator to not be
+ re-seeded correctly when creating a subshell.
+
+ww. Fixed a bug that could cause the bash replacement getcwd to overwrite
+ memory.
+
+xx. Fixed a bug that caused the shell to not receive SIGINT if it was sent
+ while the shell was waiting for a command substitution to terminate, and
+ make sure the exit status is correct when it does.
+
+yy. Fixed a bug that resulted in the second and subsequent children spawned
+ by a shell begun to run a command substitution being placed into the
+ wrong process group.
+
+zz. Fixed a bug that caused the results of successful tilde expansion to be
+ subject to pathname expansion and word splitting.
+
+aaa. Fixed a bug that could cause the shell to hang if it encountered an
+ error that caused it to jump back to the top processing loop during a
+ command substitution or `eval' command.
+
+bbb. Fixed a bug that caused the `read' builtin to use the tty's attributes
+ instead of those of the file descriptor passed with the -u option when
+ processing the -n and -d options.
+
+ccc. Fixed a bug that caused incorrect expansion of ${array[@]:foo} if the
+ first character of $IFS was not whitespace.
+
+ddd. Fixed a bug that occurred when scanning for the ending delimiter of a
+ ${parameter/pat/sub} expansion.
+
+eee. Fixed a bug that caused the shell to inappropriately expand command
+ substitutions in words when expanding directory names for completion.
+
+fff. Fixed a bug that caused the `fc' builtin to look too far back in the
+ history list under certain circumstances.
+
+ggg. Fixed a bug that caused a shell running in Posix mode to search $PWD for
+ a file specified as an argument to source/. when the file was not found
+ in $PATH.
+
+hhh. Fixed a bug that caused the shell to modify the case of a command word
+ found via command completion when the shell was performing case-
+ insensitive completion.
+
+iii. Fixed a bug that caused the shell to search $PATH for an argument to
+ source/. even when it contained a `/'.
+
+jjj. Fixed a bug that caused brace expansion to misorder expansions when the
+ locale did not have a collating order like aAbBcC...zZ.
+
+kkk. Fixed a bug that did not allow `set +o history' to have any effect when
+ run in a startup file or from a sourced file.
+
+lll. Fixed a bug with the precedence of the ?: conditional arithmetic operator.
+
+mmm. Fixed a bug that caused side effects of temporary variable assignments

+ command was supposed to be ignored.
+
+qqq. Fixed a bug that caused the shell to attempt to created variables with
+ invalid names if such names appeared in the initial environment.
+
+rrr. Fixed a bug with quote removal in strings where the final character is a
+ backslash.
+
+sss. Fixed a bug that caused the effects of special variables to persist even
+ when the variables were unset as part of the shell reinitializing itself
+ to execute a shell script.
+
+ttt. Fixed a bug that caused the history to not be saved after `history -c' or
+ `history -d' was executed until a sufficient number of commands had been
+ saved to the history.
+
+uuu. Bash now parses command substitutions according to Posix rules: parsing
+ the command contained in $() to find the closing delimiter.
+
+vvv. Fixed a bug that caused traps on SIGCHLD set in a SIGCHLD handler to
+ not persist.
+
+www. Fixed a bug that didn't allow SIGCHLD to interrupt the `wait' builtin
+ as Posix specifies.
+
+xxx. Invalid numeric arguments to shell builtins no longer cause the shell to
+ short-circuit any executing compound command.
+
+yyy. Fixed a bug that caused the exit status to be lost when `break' was
+ used to short-circuit a loop's execution.
+
+zzz. Fixed a bug that caused stray ^? characters to be left in expansions of

+
+eeee. The shell displays more warnings about failures to set the locale.
+

+ had /dev/fd available, resulting in problems with process substitution.
+
+2. Changes to Readline
+
+a. Fixed a number of redisplay errors in environments supporting multibyte
+ characters.
+
+b. Fixed bugs in vi command mode that caused motion commands to inappropriately
+ set the mark.
+
+c. When using the arrow keys in vi insertion mode, readline allows movement
+ beyond the current end of the line (unlike command mode).
+
+d. Fixed bugs that caused readline to loop when the terminal has been taken
+ away and reads return -1/EIO.
+
+e. Fixed bugs in redisplay occurring when displaying prompts containing
+ invisible characters.
+
+f. Fixed a bug that caused the completion append character to not be reset to
+ the default after an application-specified completion function changed it.
+
+g. Fixed a problem that caused incorrect positioning of the cursor while in
+ emacs editing mode when moving forward at the end of a line while using
+ a locale supporting multibyte characters.
+
+h. Fixed an off-by-one error that caused readline to drop every 511th
+ character of buffered input.
+
+i. Fixed a bug that resulted in SIGTERM not being caught or cleaned up.
+
+j. Fixed redisplay bugs caused by multiline prompts with invisible characters
+ or no characters following the final newline.
+
+k. Fixed redisplay bug caused by prompts consisting solely of invisible
+ characters.
+
+l. Fixed a bug in the code that buffers characters received very quickly in
+ succession which caused characters to be dropped.
+
+m. Fixed a bug that caused readline to reference uninitialized data structures
+ if it received a SIGWINCH before completing initialzation.
+
+n. Fixed a bug that caused the vi-mode `last command' to be set incorrectly
+ and therefore unrepeatable.
+
+o. Fixed a bug that caused readline to disable echoing when it was being used
+ with an output file descriptor that was not a terminal.
+
+p. Readline now blocks SIGINT while manipulating internal data structures
+ during redisplay.
+
+q. Fixed a bug in redisplay that caused readline to segfault when pasting a
+ very long line (over 130,000 characters).
+
+r. Fixed bugs in redisplay when using prompts with no visible printing
+ characters.
+
+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.

+
+b. Fixed a bug in the printf builtin that caused the %q format specifier to
+ ignore empty string arguments.
+
+c. Improved multibyte character environment detection at configuration time.
+
+d. Fixed a bug in the read builtin that left spurious escape characters in the
+ input after processing backslashes when assigning to an array variable.
+
+2. Changes to Readline
+
+a. Fixed a redisplay bug that occurred in multibyte-capable locales when the
+ prompt was one character longer than the screen width.
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.2-beta,
+and the previous version, bash-3.2-alpha.

+ process substitution.
+
+c. Fixed problems with cross-compiling originating from inherited environment
+ variables.
+
+d. Added write error reporting to printf builtin.
+
+e. Fixed a bug in the variable expansion code that could cause a core dump in

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

+
+4. New Features in Readline
+
+a. A new external application-controllable variable that allows the LINES
+ and COLUMNS environment variables to set the window size regardless of
+ what the kernel returns.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.1-rc1,
+and the previous version, bash-3.1-beta1.
+
+1. Changes to Bash
+
+a. Fixed a bug that could cause core dumps due to accessing the current

+
+b. Fixed a bug that caused pathnames with backslashes still quoting characters
+ to be passed to opendir().
+
+c. Command word completion now obeys the setting of completion-ignore-case.
+
+d. Fixed a problem with redirection that caused file descriptors greater than
+ 2 to be inappropriately marked as close-on-exec.
+
+e. In Posix mode, after `wait' is called to wait for a particular process
+ explicitly, that process is removed from the list of processes known to
+ the shell, and subsequent attempts to wait for it return errors.
+
+f. Fixed a bug that caused extended pattern matching to incorrectly scan
+ backslash-escaped pattern characters.
+
+g. Fixed a synchronization problem that could cause core dumps when handling
+ a SIGWINCH.

+
+j. Fix for MacOS X so it gets the values for the HOSTTYPE, MACHTYPE, and
+ OSTYPE variables at build time, to support universal binaries.
+
+k. Fixed a bug that could cause an exit trap to return the exit status of
+ the trap command rather than the status as it was before the trap was
+ run as the shell's exit status.
+
+2. New Features in Bash
+
+3. Changes to Readline
+
+a. Fixed a bug that caused reversing the incremental search direction to
+ not work correctly.
+
+b. Fixed the vi-mode `U' command to only undo up to the first time insert mode

+ place.
+
+4. New Features in Readline
+
+a. New application-callable auxiliary function, rl_variable_value, returns
+ a string corresponding to a readline variable's value.
+
+b. When parsing inputrc files and variable binding commands, the parser

+
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.1-beta1,
+and the previous version, bash-3.1-alpha1.
+
+1. Changes to Bash
+
+a. Added some system-specific signal names.
+
+b. Fixed a typo in the ulimit builtin to make `x' the right option to
+ maniuplate the limit on file locks.
+
+c. Fixed a problem with using += to append to index 0 of an array variable
+ 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
+ directory as `.', even when displaying $PWD.
+
+n. Fixed a problem with the `read' builtin when reading a script from standard
+ input and reading data from the same file.
+
+o. Fixed a problem with the `type' and `command' builtins that caused absolute
+ pathnames to be displayed incorrectly.
+
+p. Some changes to the `bg' builtin for POSIX conformance.
+
+q. The `fc' builtin now removes the `fc' command that caused it to invoke an
+ editor on specified history entries from the history entirely, rather than
+ simply ignoring it.
+
+r. 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.
+
+1. Changes to Bash
+
+a. Fixed a bug that caused bash to crash if referencing an unset local array.
+
+b. Fixed a problem that caused tilde expansion to not be performed before
+ attempting globbing word completion.
+
+c. Fixed an incompatibility so that a first argument to trap that's a valid
+ signal number will be trated as a signal rather than a command to execute.
+
+d. Fixed ${#word} expansion to correctly compute the length of a string
+ containing multibyte characters.
+
+e. Fixed a bug that caused bash to not pass the correct flags for signal
+ disposition to child processes.
+
+f. Fixed a bug that caused `fc -l' to list one too many history entries.
+
+g. Some fixes to `fc' for POSIX conformance.
+
+h. Some fixes to job status display for POSIX conformance.
+
+i. Fixed a bug that caused `command -v' to display output if a command was not
+ found -- it should be silent.
+
+j. In POSIX mode, `type' and `command -[vV]' do not report non-executable
+ files, even if the shell will attempt to execute them.
+
+k. Fixed a bug that caused the `==' operator to the [[ command to not attempt
+ extended pattern matching.
+
+l. Fixed the brace expansion code to handle characters whose value exceeds 128.
+
+m. Fixed `printf' to handle strings with a leading `\0' whose length is
+ non-zero.
+
+n. Fixed a couple of problems with brace expansion where `${' was handled
+ incorrectly.
+
+o. Fixed off-by-one error when calculating the upper bound of `offset' when
+ processing the ${array[@]:offset:length} expansion.
+

+ 10.4, Linux 2.4+ kernels, Linux 3.x kernels, Dragonfly BSD, QNX 6.x,
+ Cygwin
+
+q. Fixed a bug that caused the shell to ignore the status of the rightmost
+ command in a pipeline when the `pipefail' option was enabled.
+
+r. Fixed a completion bug that caused core dumps when expanding a directory
+ name.
+
+s. Fixed a bug that prevented `hash -d' from removing commands from the hash
+ table.
+
+t. Fixed word splitting to avoid really bad quadratic performance when
+ expanding long lists.
+
+u. Fixed a bug that caused negative offsets in substring expansion to use the
+ wrong values.
+
+v. Fixed a bug in printf that caused it to not return failure on write errors.
+
+w. Fixed a bug that caused commands in subshells to not be properly timed.
+
+x. The shell parser no longer attempts to parse a compound assignment specially
+ unless in a position where an assignment statement is acceptable or parsing
+ arguments to a builtin that accepts assignment statements.
+
+y. Fixed a problem that caused a `case' statement to be added to the history
+ incorrectly as a single command if the `case word' was on one line and the
+ `in' on another.
+
+z. Fixed a problem that caused internal shell quoting characters to be
+ incorrectly quoted with backslashes under some circumstances.
+
+aa. The shell now performs correct word splitting when IFS contains multibyte
+ characters.
+
+bb. The mail checking code now resets the cached file information if the size
+ drops to 0, even if the times don't change.
+
+cc. A completed command name that is found in $PATH as well as the name of a
+ directory in the current directory no longer has a slash appended in certain
+ circumstances: a single instance found in $PATH when `.' is not in $PATH,
+ and multiple instances found in $PATH, even when `.' is in $PATH.
+
+dd. Incorporated tilde expansion into the word expansion code rather than as a
+ separately-called function, fixing some cases where it was performed
+ inappropriately (e.g., after the second `=' in an assignment statement or
+ in a double-quoted parameter expansion).
+
+ee. Fixed several bugs encountered when parsing compound assignment statements,
+ so that compound assignments appearing as arguments to builtins are no
+ longer double-expanded.
+
+ff. Fixed a bug in the command execution code that caused asynchronous commands
+ containing command substitutions to not put the terminal in the wrong
+ process group.
+
+gg. Bash now handles the case where the WCONTINUED flag causes waitpid() to
+ return -1/EINVAL at runtime as well as configuration time.
+
+hh. Fixed parser to generate an error when the pipeline `argument' to `!' or
+ `time' is NULL.
+
+ii. The shell now takes a little more care when manipulating file descriptors
+ greater than 9 with the `exec' builtin.
+
+jj. Fixed a bug that caused variable assignments preceding the `command' builtin
+ preceding a special builtin to be preserved after the command completed in
+ POSIX mode.
+
+kk. Fixed a bug that allowed variables beginning with a digit to be created.
+
+ll. Fixed a bug that caused a \<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
+ no `/' to be appended to a directory name.
+
+j. Fixed forward-word and backward-word to work when words contained
+ multibyte characters.
+
+k. Fixed a bug in finding the delimiter of a `?' substring when performing
+ history expansion in a locale that supports multibyte characters.
+
+l. Fixed a memory leak caused by not freeing the timestamp in a history entry.
+
+m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting
+ of the `convert-meta' variable.
+
+n. Fixed saving and restoring primary prompt when prompting for incremental
+ and non-incremental searches; search prompts now display multibyte
+ characters correctly.
+
+o. Fixed a bug that caused keys originally bound to self-insert but shadowed
+ by a multi-character key sequence to not be inserted.
+
+p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
+ dereferenced if NULL (matching the documentation).
+
+q. Extensive changes to readline to add enough state so that commands
+ requiring additional characters (searches, multi-key sequences, numeric
+ arguments, commands requiring an additional specifier character like
+ vi-mode change-char, etc.) work without synchronously waiting for
+ additional input.
+
+r. Lots of changes so readline builds and runs on MinGW.
+
+s. Readline no longer tries to modify the terminal settings when running in
+ callback mode.
+
+t. The Readline display code no longer sets the location of the last invisible
+ character in the prompt if the \[\] sequence is empty.
+
+3. New Features in Bash
+
+a. Bash now understands LC_TIME as a special variable so that time display
+ tracks the current locale.
+
+b. BASH_ARGC, BASH_ARGV, BASH_SOURCE, and BASH_LINENO are no longer created
+ as `invisible' variables and may not be unset.
+
+c. In POSIX mode, if `xpg_echo' option is enabled, the `echo' builtin doesn't
+ try to interpret any options at all, as POSIX requires.
+
+d. The `bg' builtin now accepts multiple arguments, as POSIX seems to specify.
+
+e. Fixed vi-mode word completion and glob expansion to perform tilde
+ expansion.
+
+f. The `**' mathematic exponentiation operator is now right-associative.
+
+g. The `ulimit' builtin has new options: -i (max number of pending signals),
+ -q (max size of POSIX message queues), and -x (max number of file locks).
+
+h. A bare `%' once again expands to the current job when used as a job
+ specifier.
+
+i. The `+=' assignment operator (append to the value of a string or array) is
+ now supported for assignment statements and arguments to builtin commands
+ that accept assignment statements.
+
+j. BASH_COMMAND now preserves its value when a DEBUG trap is executed.
+
+k. The `gnu_errfmt' option is enabled automatically if the shell is running
+ in an emacs terminal window.
+
+l. New configuration option: --single-help-strings. Causes long help text
+ to be written as a single string; intended to ease translation.
+
+m. The COMP_WORDBREAKS variable now causes the list of word break characters
+ to be emptied when the variable is unset.
+
+n. An unquoted expansion of $* when $IFS is empty now causes the positional
+ parameters to be concatenated if the expansion doesn't undergo word
+ splitting.
+
+o. Bash now inherits $_ from the environment if it appears there at startup.
+
+p. New shell option: nocasematch. If non-zero, shell pattern matching ignores
+ case when used by `case' and `[[' commands.
+
+q. The `printf' builtin takes a new option: -v var. That causes the output
+ to be placed into var instead of on stdout.
+
+r. By default, the shell no longer reports processes dying from SIGPIPE.
+
+s. Bash now sets the extern variable `environ' to the export environment it
+ creates, so C library functions that call getenv() (and can't use the
+ shell-provided replacement) get current values of environment variables.
+
+4. New Features in Readline
+
+a. The key sequence sent by the keypad `delete' key is now automatically
+ bound to delete-char.
+
+b. A negative argument to menu-complete now cycles backward through the
+ completion list.
+
+c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
+ readline will bind the terminal special characters to their readline
+ equivalents when it's called (on by default).
+
+d. New bindable command: vi-rubout. Saves deleted text for possible
+ reinsertion, as with any vi-mode `text modification' command; `X' is bound
+ to this in vi command mode.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-release,
+and the previous version, bash-3.0-rc1.
+
+1. Changes to Bash
+
+a. Fixed a boundary overrun that could cause segmentation faults when the
+ completion code hands an incomplete construct to the word expansion
+ functions.
+
+b. Changed posix mode behavior so that an error in a variable assignment
+ preceding a special builtin causes a non-interactive shell to exit.
+
+c. Change the directory expansion portion of the completion code to not
+ expand embedded command substitutions if the directory name appears in
+ the file system.
+
+d. Fixed a problem that caused `bash -r' to turn on restrictions before
+ reading the startup files.
+
+e. Fixed a problem with the default operation of the `umask' builtin.
+
+2. Changes to Readline
+
+a. Fixed a problem with readline saving the contents of the current line
+ before beginning a non-interactive search.
+
+b. Fixed a problem with EOF detection when using rl_event_hook.
+
+c. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric
+ arguments.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-rc1,
+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
+ an array using $array, element 0 was unset, and `set -u' was enabled.
+
+b. System-specific changes for: SCO Unix 3.2, Tandem.
+
+c. Fixed a bug that caused inappropriate word splitting when a variable was
+ expanded within a double-quoted string that also included $@.
+
+d. Fixed a bug that caused `pwd' to not display anything in physical mode
+ when the file system had changed underneath the shell.
+
+e. Fixed a bug in the pre- and post- increment and decrement parsing in the
+ expression evaluator that caused errors when the operands and corresponding
+ operators were separated by whitespace.
+
+f. Fixed a bug that caused `history -p' to add an entry to the history list,
+ counter to the documentation. (Keeps the history expansions invoked by
+ emacs-mode command line editing from doing that as well.)
+
+g. Fixed a bug that could cause a core dump if `cd' is asked to print out a
+ pathname longer than PATH_MAX characters.
+
+h. Fixed a bug that caused jobs to be put into the wrong process group under
+ some circumstances after enabling job control with `set -m'.
+
+i. `unalias' now returns failure if no alias name arguments are supplied.
+
+j. Documented the characters not allowed to appear in an alias name.
+
+k. $* is no longer expanded as if in double quotes when it appears in the
+ body of a here document, as the SUS seems to require.
+
+l. The `bashbug' script now uses a directory in $TMPDIR for exclusive
+ access rather than trying to guess how the underlying OS provides for
+ secure temporary file creation.
+
+m. Fixed a few problems with `cd' and `pwd' when asked to operate on pathnames
+ longer than PATH_MAX characters.
+
+n. Fixed a memory leak caused when creating multiple local array variables
+ with identical names.
+
+o. Fixed a problem with calls to getcwd() so that bash now operates better
+ when the full pathname to the current directory is longer than PATH_MAX
+ bytes.
+
+p. The `trap' builtin now reports an error if a single non-signal argument
+ is specified.
+
+q. Fixed a bug that caused `umask' to not work correctly when presented
+ with a mask of all 0s.
+
+r. When `getopts' reaches the end of options, OPTARG is unset, as POSIX
+ appears to specify.
+
+s. Interactive mode now depends on whether or not stdin and stderr are
+ connected to a tty; formerly it was stdin and stdout. POSIX requires
+ this.
+
+t. Fixed vi-mode completion to work more as POSIX specifies (e.g., doing the
+ right kind of filename generation).
+
+2. Changes to Readline
+
+a. Fixed a problem that could cause readline to refer to freed memory when
+ moving between history lines while doing searches.
+
+b. Improvements to the code that expands and displays prompt strings
+ containing multibyte characters.
+
+c. Fixed a problem with vi-mode not correctly remembering the numeric argument
+ to the last `c'hange command for later use with `.'.
+
+d. Fixed a bug in vi-mode that caused multi-digit count arguments to work
+ incorrectly.
+
+e. Fixed a problem in vi-mode that caused the last text modification command
+ to not be remembered across different command lines.
+
+f. Fixed problems with changing characters and changing case at the end of
+ the line.

+
+a. The `jobs', `kill', and `wait' builtins now accept job control notation
+ even if job control is not enabled.
+
+b. The historical behavior of `trap' that allows a missing `action' argument

+
+a. When listing completions, directories have a `/' appended if the
+ `mark-directories' option has been enabled.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-beta1,
+and the previous version, bash-3.0-alpha.
+
+1. Changes to Bash
+
+a. Fixes to build correctly when arrays are not compiled into the shell.
+
+b. Fixed command substitution to run any exit trap defined in the command
+ substitution before returning; the exit trap is not inherited from the
+ calling shell.
+
+c. 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.
+
+d. Fixed processing of octal and hex constants in printf builtin for POSIX.2
+ compliance.
+
+e. Fixed a couple of core dumps in the pattern removal code.
+
+f. Fixes to the array subrange extraction code to deal better with sparse
+ arrays.
+
+g. Parser errors and other errors that result in the shell exiting now cause
+ the exit trap to be run.
+
+h. Change the command substitution completion functions to not append any
+ closing quote, because it would be inserted a closing "`" or ")".
+
+i. Fix history initialization so assignments to $histchars made in startup
+ files are honored.
+
+j. If an exit trap does not contain a call to `exit', the shell now uses
+ the exit status of the last command executed before the trap as the exit
+ status of the shell.
+
+k. The parser now prompts with $PS2 if it reads a newline while parsing a
+ compound array assignment statement.
+
+l. When performing a compound array assignment, the parser doesn't treat
+ words of the form [index]=value as assignments if they're the result of
+ expansions.
+
+m. Fixed a bug that caused `return' executed in a trap command to make the
+ shell think it was still running the trap.
+
+n. Fixed the value of errno set by the pathname canonicalization functions.
+
+o. Changed the grammar so that `time' alone on a line times a null command
+ rather than being a syntax error.
+
+p. The pattern substitution code no longer performs quote removal on the
+ pattern before trying to match it, as the pattern removal functions do.
+
+q. Fixed a bug that could cause core dumps when checking whether a quoted
+ command name was being completed.
+
+r. Fixes to the pattern removal and pattern replacement expansions to deal
+ with multibyte characters better (and faster).
+
+s. Fix to the substring expansion (${param:off[:len]}) to deal with (possibly
+ multibyte) characters instead of raw bytes.
+
+t. Fixed a bug that caused some key bindings set in an inputrc to be ignored
+ at shell startup.
+
+u. Fixed a bug that caused unsetting a local variable within a function to
+ not work correctly.
+
+v. Fixed a bug that caused invalid variables to be created when using
+ `read -a'.
+
+w. Fixed a bug that caused "$@" to expand incorrectly when used as the right
+ hand side of a parameter expansion such as ${word:="$@"} if the first
+ character of $IFS was not a space.
+
+x. 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().
+
+qq. Fixed a bug that caused expansions like #{a[2]:=value} to create the
+ appropriate array element instead of a variable named `a[2]'.
+
+rr. Fixed a bug in the handling of a `?(...)' pattern immediately following
+ a `*' when extglob is enabled.
+
+ss. Fixed a bug that caused a `return' invoked in an exit trap when exit is
+ invoked in a function to misbehave.
+
+tt. Fixed a bug that caused CTLESC and CTLNUL characters to not be escaped
+ by the internal shell string quoting functions.
+
+uu. Fixed a bug that caused quoted null characters in an expanded word list
+ to be inappropriately assigned to an array variable when using `read -a'.
+
+vv. Fixed a bug that caused redirections accompanying a null command to persist
+ in the current shell.
+
+ww. Fixed a bug that caused the prompt to be printed when the shell was
+ expanding a multiline alias.
+
+xx. Fixed a bug that resulted in core dumps when the completion for a command
+ changed the compspec.
+
+yy. Fixed a bug that caused evaluation of programmable completions to print
+ notifications of completed jobs.
+
+zz. Bash now disables line editing when $EMACS == `t' and $TERM == `dumb'
+ (which is what emacs shell windows do).
+
+aaa. In posix mode, `kill -l' causes signal names to be displayed without
+ a leading `SIG'.
+
+bbb. Clear error flag on standard output so it doesn't persist across multiple
+ builtin commands.
+
+ccc. In posix mode, `alias' displays alias values without the leading `alias',
+ so the output cannot be used as subsequent input.
+
+ddd. In posix mode, the `trap' builtin doesn't check whether or not its
+ first argument is a signal specification and revert the signal handling
+ to its original disposition if it is.
+
+eee. Fixed several bugs in the handling of "$*" and "${array[*]}" by the
+ pattern substitution and removal expansions.
+
+fff. Fixed several problems with the handling of ${array[@]}, ${array[*]},
+ $@, and $* by the indirect variable expansion code.
+
+ggg. Fixed a bug that did not allow `time' to be aliased.
+
+hhh. Improved the mail checking code so it won't check (and possibly cause an
+ NFS file system mount) until MAILPATH or MAIL is given a value -- there
+ is no default if DEFAULT_MAIL_DIRECTORY is not defined at compile time.
+ (It is computed by configure, but can be #undef'd in config-bot.h.)
+
+iii. If the `chkwinsize' option is enabled, the shell checks for window size
+ changes if a child process exits due to a signal.
+
+jjj. Removed the attempts to avoid adding a slash at the end of a completed
+ executable name if there was a directory with the same name in the
+ current directory.
+
+kkk. Fixed PATH lookup code so it treats the permission bits separately for
+ owner, group, and other, rather than checking them all.
+
+lll. Fixed the locale code to reset the parser's idea of the character class
+ <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()
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-release,

+
+1. Changes to Bash
+
+a. Fixed an off-by-one error in the function that translates job
+ specifications.
+
+b. Note that we're running under Emacs and disable line editing if
+ $EMACS == `t'.

+
+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.

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

+
+j. Bashbug now tries harder to find a usable editor if $EDITOR is not set,

+ 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

+
+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

+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta1,
+and the previous version, bash-2.04-alpha1.
+
+1. Changes to Bash
+
+a. Fixed a bug in the programmable completion code that occurred when

+
+b. The file descriptor from which the shell is reading a script is now
+ moved to a file descriptor above the user-addressible range.
+
+c. Changes to `printf' so that it can handle integers beginning with 0
+ or 0x as octal and hex, respectively.
+
+d. Fixes to the programmable completion code so it handles nonsense like
+ `compgen -C xyz' gracefully.
+
+e. The shell no longer modifies the signal handler for SIGPROF, allowing
+ profiling again on certain systems.
+
+f. The shell checks for a new window size, if the user has requested it,
+ after a process exits due to a signal.
+
+g. Fixed a bug with variables with null values in a program's temporary
+ environment and the bash getenv() replacement.
+
+h. `declare' and the other builtins that take variable assignments as
+ arguments now honor `set -a' and mark modified variables for export.
+
+i. Some changes were made for --dump-po-strings mode when writing strings
+ with embedded newlines.
+
+j. The code that caches export strings from the initial environment now
+ duplicates the string rather than just pointing into the environment.
+
+k. The filename completion quoting code now uses single quotes by default
+ if the filename being completed contains newlines, since \<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.

+ state.
+
+ee. `bashbug' now honors user headers in the mail message it sends.
+
+ff. A bug was fixed that caused the `:p' history modifier to not print the
+ history expansion if the `histverify' option was set.
+
+2. Changes to Readline
+
+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.

+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.

+ of a readonly shell variable (declared with the `local' builtin).
+
+2. Changes to Readline
+

+ the history file on cygwin32.
+
+3. New Features in Bash

+
+b. configure has a new option, `--enable-progcomp', to compile in the
+ programmable completion features (enabled by default).
+
+c. `shopt' has a new option, `progcomp', to enable and disable programmable
+ completion at runtime.
+
+d. Unsetting HOSTFILE now clears the list of hostnames used for completion.
+
+4. New Features in Readline
+
+a. A new variable, rl_gnu_readline_p, always 1. The intent is that an
+ application can verify whether or not it is linked with the `real'
+ readline library or some substitute.

+
+m. Improvements were made to the `read' builtin so that it makes many
+ fewer read(2) system calls.
+
+n. The expansion of $- will include `c' and `s' when those options are
+ supplied at shell invocation.

+ simplified considerably and should work better now.
+
+x. Fixes to the non-job-control code in nojobs.c to make it POSIX.2-compliant
+ when a user attempts to retrieve the status of a terminated background
+ process.
+
+y. Fixes to the `printf' builtin so that it doesn't try to expand all
+ backslash escape sequences in the format string before parsing it for
+ % format specifiers.
+
+2. Changes to Readline
+
+a. The history library tries to truncate the history file only if it is a
+ regular file.

+
+k. More support for __EMX__ (OS/2).
+
+l. A bug was fixed in readline's signal handling that could cause infinite

+ was given a very large numeric argument.
+
+n. The vi-mode code now gets characters via the application-settable value
+ of rl_getc_function rather than calling rl_getc directly.
+
+3. New Features in Bash
+
+a. The history builtin has a `-d offset' option to delete the history entry
+ at position `offset'.
+
+b. The prompt expansion code has two new escape sequences: \j, the number of
+ active jobs; and \l, the basename of the shell's tty device name.
+
+c. The `bind' builtin has a new `-x' option to bind key sequences to shell
+ commands.
+
+d. There is a new shell option, no_empty_command_completion, which, when
+ enabled, disables command completion when TAB is typed on an empty line.
+
+e. The `help' builtin has a `-s' option to just print a builtin's usage
+ synopsys.
+
+f. There are several new arithmetic operators: id++, id-- (variable
+ post-increment/decrement), ++id, --id (variabl pre-increment/decrement),
+ expr1 , expr2 (comma operator).
+
+g. There is a new ksh-93 style arithmetic for command:
+ for ((expr1 ; expr2; expr3 )); do list; done
+
+h. The `read' builtin has a number of new options:
+ -t timeout only wait timeout seconds for input
+ -n nchars only read nchars from input instead of a full line
+ -d delim read until delim rather than newline
+ -s don't echo input chars as they are read
+
+i. The redirection code now handles several filenames specially:
+ /dev/fd/N, /dev/stdin, /dev/stdout, and /dev/stderr, whether or
+ not they are present in the file system.
+
+j. The redirection code now recognizes pathnames of the form
+ /dev/tcp/host/port and /dev/udp/host/port, and tries to open a socket
+ of the appropriate type to the specified port on the specified host.
+
+k. The ksh-93 ${!prefix*} expansion, which expands to the names of all
+ shell variables whose names start with prefix, has been implemented.
+
+l. There is a new dynamic variable, FUNCNAME, which expands to the name of
+ a currently-executing function. Assignments to FUNCNAME have no effect.
+
+m. The GROUPS variable is no longer readonly; assignments to it are silently
+ discarded. This means it can be unset.
+
+4. New Features in Readline
+
+a. Parentheses matching is now always compiled into readline, and enabled
+ or disabled when the value of the `blink-matching-paren' variable is
+ changed.
+
+b. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+c. MS-DOS systems now use ~/_history as the default history file.

+
+e. history-search-{forward,backward} now leave the last history line found
+ in the readline buffer if the second or subsequent search fails.
+
+f. New function for use by applications: rl_on_new_line_with_prompt, used
+ when an application displays the prompt itself before calling readline().
+
+g. New variable for use by applications: rl_already_prompted. An application
+ that displays the prompt itself before calling readline() must set this to
+ a non-zero value.

+1. Changes to Bash
+
+a. A change was made to the help text for `{...}' to make it clear that a
+ semicolon is required before the closing brace.
+
+b. A fix was made to the `test' builtin so that syntax errors cause test
+ to return an exit status > 1.
+
+c. Globbing is no longer performed on assignment statements that appear as
+ arguments to `assignment builtins' such as `export'.
+
+d. System-specific configuration changes were made for: Rhapsody,
+ AIX 4.2/gcc, BSD/OS 4.0.
+
+e. New loadable builtins: ln, unlink.
+
+f. Some fixes were made to the globbing code to handle extended glob patterns
+ which immediately follow a `*'.
+
+g. A fix was made to the command printing code to ensure that redirections
+ following compound commands have a space separating them from the rest
+ of the command.
+
+h. The pathname canonicalization code was changed to produce fewer leading
+ `//' sequences, since those are interpreted as network file system
+ pathnames on some systems.
+
+i. A fix was made so that loops containing `eval' commands in commands passed
+ to `bash -c' would not exit prematurely.
+
+j. Some changes were made to the job reaping code when the shell is not
+ interactive, so the shell will retain exit statuses longer for examination
+ by `wait'.
+
+k. A fix was made so that `jobs | command' works again.
+
+l. The erroneous compound array assignment var=((...)) is now a syntax error.
+
+m. A change was made to the dynamic loading code in `enable' to support
+ Tenon's MachTen.
+
+n. A fix was made to the globbing code so that extended globbing patterns
+ will correctly match `.' in a bracket expression.
+
+2. Changes to Readline
+
+a. A fix was made to the completion code in which a typo caused the wrong
+ value to be passed to the function that computed the longest common
+ prefix of the list of matches.
+
+b. The completion code now checks the value of rl_filename_completion_desired,
+ which is set by application-supplied completion functions to indicate
+ that filename completion is being performed, to decide whether or not to
+ call an application-supplied `ignore completions' function.
+
+3. New Features in Bash
+
+a. A change was made to the startup file code so that any shell begun with
+ the `--login' option, even non-interactive shells, will source the login
+ shell startup files.
+
+4. New Features in Readline
+
+a. A new variable, rl_erase_empty_line, which, if set by an application using
+ readline, will cause readline to erase, prompt and all, lines on which the
+ only thing typed was a newline.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.03-alpha,
+and the previous version, bash-2.02.1-release.
+
+1. Changes to Bash
+
+a. System-specific configuration changes were made for: Irix 6.x, Unixware 7.
+
+b. The texi2dvi and texi2html scripts were updated to the latest versions
+ from the net.
+
+c. The configure tests that determine which native type is 32 bits were
+ changed to not require a compiled program.
+
+d. Fixed a bug in shell_execve that could cause memory to be freed twice
+ after a failed exec.
+
+e. The `printf' test uses `diff -a' if it's available to prevent confusion
+ due to the non-ascii output.
+
+f. Shared object configuration is now performed by a shell script,
+ support/shobj-conf, which generates values to be substituted into
+ makefiles by configure.
+
+g. Some changes were made to `ulimit' to avoid the use of RLIM_INVALID as a
+ return value.
+
+h. Changes were made to `ulimit' to work around HPUX 9.x's peculiar
+ handling of RLIMIT_FILESIZE.
+
+i. Some new loadable builtins were added: id, printenv, sync, whoami, push,
+ mkdir. `pushd', `popd', and `dirs' can now be built as regular or
+ loadable builtins from the same source file.
+
+j. Changes were made to `printf' to handle NUL bytes in the expanded format
+ string.
+
+k. The various `make clean' Makefile targets now descend into lib/sh.
+
+l. The `type' builtin was changed to use the internal `getopt' so that things
+ like `type -ap' work as expected.
+
+m. There is a new configuration option, --with-installed-readline, to link
+ bash with a locally-installed version of readline. Only readline version
+ 4.0 and later releases can support this. Shared and static libraries
+ are supported. The installed include files are used.
+
+n. There is a new autoconf macro used to find which basic type is 64 bits.
+
+o. Dynamic linking and loadable builtins should now work on SCO 3.2v5*,
+ AIX 4.2 with gcc, Unixware 7, and many other systems using gcc, where
+ the `-shared' options works correctly.
+
+p. A bug was fixed in the bash filename completion code that caused memory to
+ be freed twice if a directory name containing an unset variable was
+ completed and the -u option was set.
+
+q. The prompt expansion code now quotes the `$' in the `\$' expansion so it
+ 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.
+
+t. Changes to the default prompt strings if prompt string decoding is not
+ compiled into the shell.
+
+u. Added `do', `then', `else', `{', and `(' to the list of keywords that may
+ precede the `time' reserved word.
+
+v. The shell may now be cross-built for BeOS as well as cygwin32.
+
+w. The conditional command execution code now treats `=' the same as `=='
+ for deciding when to perform pattern matching.
+
+x. The `-e' option no longer causes the shell to exit if a command exits
+ with a non-zero status while running the startup files.
+
+y. The `printf' builtin no longer dumps core if a modifier is supplied in
+ the format string without a conversion character (e.g. `%h').
+
+z. Array assignments of the form a=(...) no longer show up in the history
+ list.
+
+aa. The parser was fixed to obey the POSIX.2 rules for finding the closing
+ `}' in a ${...} expression.
+
+bb. The history file is now opened with mode 0600 rather than 0666, so bash
+ no longer relies on the user's umask being set appropriately.
+
+cc. Setting LANG no longer causes LC_ALL to be assigned a value; bash now
+ 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.
+
+c. Some changes were made to the key binding code to fix memory leaks and
+ better support Win32 systems.
+
+d. Fixed a silly typo in the paren matching code -- it's microseconds, not
+ 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
+ source files uncovered by the use of prototypes.
+
+g. The maximum numeric argument is now clamped at 1000000.
+
+h. Fixes to rl_yank_last_arg to make it behave better.
+
+i. Fixed a bug in the display code that caused core dumps if the prompt
+ string length exceeded 1024 characters.
+
+j. The menu completion code was fixed to properly insert a single completion
+ if there is only one match.
+
+k. A bug was fixed that caused the display code to improperly display tabs
+ after newlines.
+
+3. New Features in Bash
+
+a. New `shopt' option, `restricted_shell', indicating whether or not the
+ shell was started in restricted mode, for use in startup files.
+
+b. Filename generation is now performed on the words between ( and ) in
+ array assignments (which it probably should have done all along).
+
+c. OLDPWD is now auto-exported, as POSIX.2 seems to require.
+
+d. ENV and BASH_ENV are read-only variables in a restricted shell.
+
+4. New Features in Readline
+
+a. Many changes to the signal handling:
+ o Readline now catches SIGQUIT and cleans up the tty before returning;
+ o A new variable, rl_catch_signals, is available to application writers
+ to indicate to readline whether or not it should install its own
+ signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+ SIGTTIN, and SIGTTOU;
+ o A new variable, rl_catch_sigwinch, is available to application
+ writers to indicate to readline whether or not it should install its
+ own signal handler for SIGWINCH, which will chain to the calling
+ applications's SIGWINCH handler, if one is installed;
+ o There is a new function, rl_free_line_state, for application signal
+ handlers to call to free up the state associated with the current
+ line after receiving a signal;
+ o There is a new function, rl_cleanup_after_signal, to clean up the
+ display and terminal state after receiving a signal;
+ o There is a new function, rl_reset_after_signal, to reinitialize the
+ terminal and display state after an application signal handler
+ returns and readline continues
+
+b. There is a new function, rl_resize_terminal, to reset readline's idea of
+ the screen size after a SIGWINCH.
+
+c. New public functions: rl_save_prompt and rl_restore_prompt. These were
+ previously private functions with a `_' prefix.
+
+d. New function hook: rl_pre_input_hook, called just before readline starts
+ reading input, after initialization.
+
+e. New function hook: rl_display_matches_hook, called when readline would
+ display the list of completion matches. The new function
+ rl_display_match_list is what readline uses internally, and is available
+ for use by application functions called via this hook.
+
+f. New bindable function, delete-char-or-list, like tcsh.
+

+ more than 1000 characters.
+
+c. Fixed a bug that caused a CDPATH entry of "" to not be treated the same

+ shell functions.
+
+j. Fixed a bug that caused the printf builtin to loop forever if the format

+
+m. Fixed a bug that caused the shell to fork too early when a command
+ such as `%2 &' was given.
+
+2. Changes to Readline
+
+a. Fixed a problem with redisplay that showed up when the prompt string was
+ longer than the screen width and the prompt contained invisible characters.

+
+k. A bug was fixed that caused local variables to be unset inappropriately
+ when sourcing a script from within another sourced script.
+
+l. A bug was fixed in the history saving code so that functions are saved
+ in the history list correctly if `cmdhist' is enabled, but `lithist'
+ is not.
+
+m. A bug was fixed that caused printf overflows when displaying error
+ messages.
+
+n. It should be easier to build the loadble builtins in examples/loadables,
+ though some manual editing of the generated Makefile is still required.

+
+q. Some changes were made to the autoconf support for Solaris 2.6 large
+ files.
+
+r. The `command' builtins now does the right thing when confstr(3) cannot

+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.02-alpha1,
+and the previous version, bash-2.01.1-release.
+
+1. Changes to Bash
+
+a. OS-specific configuration changes for: BSD/OS 3.x, Minix 2.x,
+ Solaris 2.6, SINIX SVR4.
+
+b. Changes were made to the generated `info' files so that `install-info'
+ works correctly.
+
+c. PWD is now auto-exported.

+d. A fix was made to the pipeline code to make sure that the shell forks
+ to execute simple commands consisting solely of assignment statements.
+
+e. Changes to the test suite for systems with 14-character filenames.
+
+f. The default sizes of some internal hash tables have been made smaller
+ to reduce the shell's memory footprint.
+
+g. The `((...))' arithmetic command is now executed directly instead of
+ being translated into `let "..."'.
+
+h. Fixes were made to the expansion code so that "$*", "$@", "${array[@]}",
+ and "${array[@]}" expand correctly when IFS does not contain a space
+ character, is unset, or is set to NULL.
+
+i. The indirect expansion code (${!var}) was changed so that the only
+ valid values of `var' are variable names, positional parameters, `#',
+ `@', and `*'.
+
+j. An arithmetic expression error in a $((...)) expansion now causes a
+ non-interactive shell running in posix mode to exit.
+
+k. Compound array assignment now splits the words within the parentheses
+ on shell metacharacters like the parser would before expansing them
+ and performing the assignment. This is for compatibility with ksh-93.
+
+l. The internal shell backslash-quoting code (used in the output of `set'
+ and completion) now quotes tildes if they appear at the start of the
+ string or after a `=' or `:'.

+p. The filename globbing code no longer requires read permission for a
+ directory when the filename to be matched does not contain any globbing
+ characters, as POSIX.2 specifies.
+
+q. A bug was fixed so that the job containing the last asynchronous
+ process is not removed from the job table until a `wait' is executed
+ for that process or another asynchronous process is started. This
+ satisfies a POSIX.2 requirement.
+
+r. A `select' bug was fixed so that a non-numeric user response is treated
+ the same as a numeric response that is out of range.
+
+s. The shell no longer parses the value of SHELLOPTS from the environment
+ if it is restricted, running setuid, or running in `privileged mode'.
+
+t. Fixes were made to enable large file support on systems such as
+ Solaris 2.6, where the size of a file may be larger than can be held
+ in an `int'.
+
+u. The filename hashing code was fixed to not add `./' to the beginning of
+ filenames which already begin with `./'.
+
+v. The configure script was changed so that the GNU termcap library is not
+ compiled in if `prefer-curses' has been specified.
+
+w. HISTCONTROL and HISTIGNORE are no longer applied to the second and
+ subsequent lines of a multi-line command.
+
+x. A fix was made to `disown' so that it does a better job of catching
+ out-of-range jobs.
+
+y. Non-interactive shells no longer report the status of processes terminated
+ due to SIGINT, even if the standard output is a terminal.
+
+z. A bug that caused the output of `jobs' to have extra carriage returns
+ was fixed.
+
+aa. A bug that caused PIPESTATUS to not be set when builtins or shell
+ functions were executed in the foreground was fixed.
+
+bb. Bash now attempts to detect when it is being run by sshd, and treats
+ that case identically to being run by rshd.
+
+cc. A bug that caused `set -a' to export SHELLOPTS when one of the shell
+ options was changed was fixed.
+
+dd. The `kill' builtin now disallows empty or missing process id arguments
+ instead of treating them as identical to `0', which means the current
+ process.
+
+ee. `var=value declare -x var' now behaves identically to
+ `var=value export var'. Similarly for `var=value declare -r var' and
+ `var=value readonly var'.
+
+ff. A few memory leaks were fixed.
+
+gg. `alias' and `unalias' now print error messages when passed an argument
+ that is not an alias for printing or deletion, even when the shell is
+ not interactive, as POSIX.2 specifies.
+
+hh. `alias' and `alias -p' now return a status of 0 when no aliases are
+ defined, as POSIX.2 specifes.
+
+ii. `cd -' now prints the pathname of the new working directory if the shell
+ is interactive.
+
+jj. A fix was made so that the code that binds $PWD now copes with getcwd()
+ returning NULL.
+
+kk. `unset' now checks whether or not a function name it's trying to unset
+ is a valid shell identifier only when the shell is running in posix mode.
+
+ll. A change was made to the code that generates filenames for here documents
+ to make them less prone to name collisions.
+
+mm. The parser was changed so that `time' is recognized as a reserved word
+ only at the beginning of a pipeline.
+
+nn. The pathname canonicalization code was changed so that `//' is converted
+ into `/', but all other pathnames beginning with `//' are left alone, as
+ POSIX.2 specifies.
+
+oo. The `logout' builtin will no longer exit a non-interactive non-login
+ shell.
+
+2. Changes to Readline
+
+a. Fixed a problem in the readline test program rltest.c that caused a core
+ dump.
+
+b. The code that handles parser directives in inputrc files now displays
+ more error messages.
+
+c. The history expansion code was fixed so that the appearance of the
+ history comment character at the beginning of a word inhibits history
+ expansion for that word and the rest of the input line.
+
+3. New Features in Bash
+
+a. A new version of malloc, based on the older GNU malloc, that has many
+ changes, is more page-based, is more conservative with memory usage,
+ and does not `orphan' large blocks when they are freed.
+
+b. A new version of gmalloc, based on the old GLIBC malloc, with many
+ changes and range checking included by default.
+
+c. A new implementation of fnmatch(3) that includes full POSIX.2 Basic
+ Regular Expression matching, including character classes, collating
+ symbols, equivalence classes, and support for case-insensitive pattern
+ matching.
+
+d. ksh-88 egrep-style extended pattern matching ([@+*?!](patlist)) has been
+ implemented, controlled by a new `shopt' option, `extglob'.
+
+e. There is a new ksh-like `[[' compound command, which implements
+ extended `test' functionality.
+
+f. There is a new `printf' builtin, implemented according to the POSIX.2
+ specification.
+
+g. There is a new feature for command substitution: $(< filename) now expands
+ to the contents of `filename', with any trailing newlines removed
+ (equivalent to $(cat filename)).
+
+h. There are new tilde prefixes which expand to directories from the
+ directory stack.
+
+i. There is a new `**' arithmetic operator to do exponentiation.
+
+j. There are new configuration options to control how bash is linked:
+ `--enable-profiling', to allow bash to be profiled with gprof, and
+ `--enable-static-link', to allow bash to be linked statically.
+
+k. There is a new configuration option, `--enable-cond-command', which
+ controls whether or not the `[[' command is included. It is on by
+ default.
+
+l. There is a new configuration option, `--enable-extended-glob', which
+ controls whether or not the ksh extended globbing feature is included.
+ It is enabled by default.
+
+m. There is a new configuration #define in config.h.top that, when enabled,
+ will cause all login shells to source /etc/profile and one of the user-
+ specific login shell startup files, whether or not the shell is
+ interactive.
+
+n. There is a new invocation option, `--dump-po-strings', to dump
+ a shell script's translatable strings ($"...") in GNU `po' format.
+
+o. There is a new `shopt' option, `nocaseglob', to enable case-insensitive
+ pattern matching when globbing filenames and using the `case' construct.
+
+p. There is a new `shopt' option, `huponexit', which, when enabled, causes
+ the shell to send SIGHUP to all jobs when an interactive login shell
+ exits.
+
+q. `bind' has a new `-u' option, which takes a readline function name as an
+ argument and unbinds all key sequences bound to that function in a
+ specified keymap.
+
+r. `disown' now has `-a' and `-r' options, to limit operation to all jobs
+ and running jobs, respectively.
+
+s. The `shopt' `-p' option now causes output to be displayed in a reusable
+ format.
+
+t. `test' has a new `-N' option, which returns true if the filename argument
+ has been modified since it was last accessed.
+
+u. `umask' now has a `-p' option to print output in a reusable format.
+
+v. A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...'
+ translation code. It expands to the character whose ascii code is NNN
+ in hexadecimal.
+
+w. The prompt string expansion code has a new `\r' escape sequence.
+
+x. The shell may now be cross-compiled for the CYGWIN32 environment on
+ a Unix machine.
+
+4. New Features in Readline
+
+a. There is now an option for `iterative' yank-last-arg handline, so a user
+ can keep entering `M-.', yanking the last argument of successive history
+ lines.
+
+b. New variable, `print-completions-horizontally', which causes completion
+ matches to be displayed across the screen (like `ls -x') rather than up
+ and down the screen (like `ls').
+
+c. New variable, `completion-ignore-case', which causes filename completion
+ and matching to be performed case-insensitively.
+
+d. There is a new bindable command, `magic-space', which causes history
+ expansion to be performed on the current readline buffer and a space to
+ be inserted into the result.
+
+e. There is a new bindable command, `menu-complete', which enables tcsh-like
+ menu completion (successive executions of menu-complete insert a single
+ completion match, cycling through the list of possible completions).
+
+f. There is a new bindable command, `paste-from-clipboard', for use on Win32
+ systems, to insert the text from the Win32 clipboard into the editing
+ buffer.
+
+g. The key sequence translation code now understands printf-style backslash
+ escape sequences, including \NNN octal escapes. These escape sequences
+ may be used in key sequence definitions or macro values.
+
+h. An `$include' inputrc file parser directive has been added.
+

+b. A bug was fixed that prevented `time' from timing commands correctly
+ when supplied as an argument to `bash -c'.
+
+c. A fix was made to the mail checking code to keep from adding the same
+ mail file to the list of files to check multiple times when parsing
+ $MAILPATH.
+
+d. Fixed an off-by-one error in the tilde expansion library.
+
+e. When using the compound array assignment syntax, the old value of
+ the array is cleared before assigning the new value.
+
+f. Fixed a bug that could cause a core dump when a trap handler was reset
+ to the default in the trap command associated with that signal.
+
+g. Fixed a bug in the locale code that occurred when assigning a value
+ to LC_ALL.
+
+h. A change was made to the parser so that words of the form xxx=(...)
+ are not considered compound assignment statements unless there are
+ characters before the `='.
+
+i. A fix was made to the command tracing code to correctly quote each
+ word of output.
+
+j. Some changes were made to the bash-specific autoconf tests to make them
+ more portable.
+
+k. Completion of words with globbing characters now correctly quotes the
+ result.
+
+l. The directory /var/spool/mail is now preferred to /usr/spool/mail when
+ configure is deciding on the default mail directory.
+
+m. The brace completion code was fixed to not quote the `{' and `}'.
+
+n. Some fixes were made to make $RANDOM more random in subshells.
+
+o. System-specific changes were made to configure for: SVR4.2
+
+p. Changes were made so that completion of words containing globbing chars
+ substitutes the result only if a single filename was matched.
+
+q. The window size is now recomputed after a job is stopped with SIGTSTP if
+ the user has set `checkwinsize' with `shopt'.
+
+r. When doing substring expansion, out-of-range substring specifiers now
+ cause nothing to be substituted rather than an expansion error.
+
+s. A fix was made so that you can no longer trap `SIGEXIT' or `SIGDEBUG' --
+ only `EXIT' and `DEBUG' are accepted.
+
+t. The display of trapped signals now uses the signal number if signals
+ for which bash does not know the name are trapped.
+
+u. A fix was made so that `bash -r' does not turn on restricted mode until
+ after the startup files are executed.
+
+v. A bug was fixed that occasionally caused a core dump when a variable
+ found in the temporary environment of export/declare/readonly had a
+ null value.
+
+w. A bug that occasionally caused unallocated memory to be passed to free()
+ when doing arithmetic substitution was fixed.
+
+x. A bug that caused a buffer overrun when expanding a prompt string
+ containing `\w' and ${#PWD} exceeded PATH_MAX was fixed.
+
+y. A problem with the completion code that occasionally caused it to
+ refer to a character before the beginning of the readline line buffer
+ was fixed.
+
+z. A bug was fixed so that the `read' builtin restarts reads when
+ interrupted by signals other than SIGINT.
+
+aa. Fixed a bug that caused a command to be freed twice when there was
+ an evaluation error in the `eval' command.
+
+2. Changes to Readline
+
+a. Added a missing `extern' to a declaration in readline.h that kept
+ readline from compiling cleanly on some systems.
+
+b. The history file is now opened with mode 0600 when it is written for
+ better security.
+
+c. Changes were made to the SIGWINCH handling code so that prompt redisplay
+ is done better.
+
+d. ^G now interrupts incremental searches correctly.
+
+e. A bug that caused a core dump when the set of characters to be quoted
+ when completing words was empty was fixed.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-release,
+and the previous version, bash-2.01-beta2.
+
+1. Changes to Bash
+
+a. The `distclean' target should remove the `printenv' executable if it
+ has been created.
+
+b. The test suite was changed slightly to ensure that the error messages
+ are printed in English.
+
+c. A bug that caused the shell to dump core when a filename containing a
+ `/' was passed to `hash' was fixed.
+
+d. Pathname canonicalization now leaves a leading `//' intact, as POSIX.1
+ requires.
+
+e. A memory leak when completing commands was fixed.
+
+f. A memory leak that occurred when checking the hash table for commands
+ with relative paths was fixed.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-beta2,
+and the previous version, bash-2.01-beta1.
+
+1. Changes to Bash
+
+a. The `ulimit' builtin translates RLIM_INFINITY to the hard limit only if
+ the current (soft) limit is less than or equal to the hard limit.
+
+b. Fixed a bug that caused the bash emulation of strcasecmp to produce
+ incorrect results.
+
+c. A bug that caused memory to be freed twice when a trap handler resets
+ the trap more than once was fixed.
+
+d. A bug that caused machines where sizeof (pointer) > sizeof (int) to
+ fail (and possibly dump core) when trying to unwind-protect a null
+ pointer was fixed.
+
+e. The startup files should not be run with job control enabled. This fix
+ allows SIGINT to once again interrupt startup file execution.
+
+f. Bash should not change the SIGPROF handler if it is set to something
+ other than SIG_DFL.
+
+g. The completion code that provides bash-specific completions for readline
+ now quotes characters that the readline code would treat as word break
+ characters if they appear in a file name.
+
+h. The completion code now correctly quotes filenames containing a `!',
+ even if the user attempted to use double quotes when attempting
+ completion.
+
+i. A bug that caused the shell to dump core when `disown' was called without
+ arguments and there was no current job was fixed.
+
+j. A construct like $((foo);bar) is now processed as a command substitution
+ rather than as a bad arithmetic substitution.
+
+k. A couple of bugs that caused `fc' to not obey the `cmdhist' and `lithist'
+ shell options when editing and re-executing a series of commands were
+ fixed.
+
+l. A fix was made to the grammar -- the list of commands between `do' and
+ `done' in the body of a `for' command should be treated the same as a
+ while loop.
+
+2. Changes to Readline
+
+a. A couple of bugs that caused the history search functions to attempt to
+ free a NULL pointer were fixed.
+
+b. If the C library provides setlocale(3), readline does not need to look
+ at various environment variables to decide whether or not to go into
+ eight-bit mode automatically -- just check whether the current locale
+ is not `C' or `POSIX'.
+
+c. If the filename completion function finds that a directory was not closed
+ by a previous (interrupted) completion, it closes the directory with
+ closedir().
+
+3. New Features in Bash
+
+a. New bindable readline commands: history-and-alias-expand-line and
+ alias-expand-line. The code was always in there, there was just no
+ way to execute it.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-beta1,
+and the previous version, bash-2.01-alpha1.
+
+1. Changes to Bash

+ substitution to conflict with those used explicitly in redirections.
+
+b. Made it easier to regenerate configure if the user changes configure.in.
+
+c. ${GROUPS[0]} should always be the primary group, even on systems without
+ multiple groups.
+
+d. Spelling correction is no longer enabled by default.

+g. OS-specific code changes were made for: QNX.
+
+h. A more meaningful message is now printed when the file in /tmp for a
+ here document cannot be created.
+
+i. Many changes to the shell's variable initialization code to speed
+ non-interactive startup.
+
+j. Changes to the non-job-control code so that it does not try to open
+ /dev/tty.
+
+k. The output of `set' and `export' is once again sorted, as POSIX wants.
+
+l. Fixed a problem caused by a recursive call reparsing the value of
+ $SHELLOPTS.
+
+m. The tilde code no longer calls getenv() when it's compiled as part of
+ the shell, which should eliminate problems on systems that cannot
+ redefine getenv(), like the NeXT OS.
+
+n. Fixed a problem that caused `bash -o' or `bash +o' to not list all
+ the shell options.
+
+o. Fixed `ulimit' to convert RLIM_INFINITY to the appropriate hard limit
+ only if the hard limit is greater than the current (soft) limit.
+
+p. Fixed a problem that arose when building bash in a different directory
+ than the source and y.tab.[ch] were remade with something other than
+ bison. This came up most often on NetBSD.
+
+q. Fixed a problem with completion -- it thought that `pwd`/[TAB] indicated
+ an unfinished command completion (`/), which generated errors.
+
+r. The bash special tilde expansions (~-, ~+) are now attempted before
+ calling the standard tilde expansion code, which should eliminate the
+ problems people have been seeing with this on Solaris 2.5.1.
+
+s. Added support for <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.
+
+u. A number of changes to speed up export environment creation were made.
+
+v. A number of memory leaks were fixed as the result of running the test
+ scripts through Purify.
+
+w. Fixed a bug that caused subshells forked to interpret executable
+ scripts without a leading `#!' to not reinitialize the values of
+ the shell options.
+
+2. Changes to Readline
+
+a. History library has less `#ifdef SHELL' code -- abstracted stuff out
+ into application-specific function hooks.
+
+b. Readline no longer calls getenv() if it's compiled as part of the shell,
+ which should eliminate problems on systems that cannot redefine getenv(),
+ like the NeXT OS.
+
+c. Fixed translation of ESC when `untranslating' macro values.
+
+d. The region kill operation now fixes the mark if it ends up beyond the
+ boundaries of the line after the region is deleted.
+
+3. New Features in Bash
+
+a. New argument for `configure': `--with-curses'. This can be used to
+ override the selection of the termcap library on systems where it is
+ deficient.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-alpha1,
+and the previous version, bash-2.0-release.
+
+1. Changes to Bash
+
+a. System-specific configuration changes for: FreeBSD, SunOS4, Irix,
+ MachTen, QNX 4.2, Harris Night Hawk, SunOS5.
+
+b. System-specific code changes were made for: Linux, 4.4 BSD, QNX 4.2,
+ HP-UX, AIX 4.2.
+
+c. A bug that caused the exec builtin to fail because the full pathname of
+ the command could not be found was fixed.
+
+d. The code that performs output redirections is now more resistant to
+ race conditions and possible security exploits.
+
+e. A bug that caused the shell to dump core when performing pattern
+ substitutions on variable values was fixed.
+
+f. More hosts are now recognized by the auto-configuration mechanism
+ (OpenBSD, QNX, others).
+
+g. Assignments to read-only variables that attempt to convert them to
+ arrays are now errors.
+
+h. A bug that caused shell scripts using array assignments in POSIX mode
+ to exit after the assignment was performed was fixed.
+
+i. The substring expansion code is now more careful about running off the
+ ends of the expanded variable value.
+
+j. A bug that caused completion to fail if a backquoted command substitution
+ appeared anywhere on the line was fixed.
+
+k. The `source' builtin no longer turns off history if it has been enabled
+ in a non-interactive shell.
+
+l. A bug that caused the shell to crash when `disown' was given a pid
+ instead of a job number was fixed.
+
+m. The `cd' spelling correction code will not try to change to `.' if no
+ directory entries match a single-character argument.
+
+n. A bad variable name supplied to `declare', `export', or `readonly' no
+ longer causes a non-interactive shell in POSIX mode to exit.
+
+o. Some fixes were made to the test suite to handle peculiarities of
+ various Unix versions.
+
+p. The bash completion code now quotes characters that readline would
+ treat as word breaks for completion but are not shell metacharacters.
+
+q. Bad options supplied at invocation now cause a usage message to be
+ displayed.
+
+r. Fixes were made to the code that handles DEBUG traps so that the trap
+ string is not freed inappropriately.
+
+s. Some changes were made to the bash debugger in examples/bashdb -- it
+ should be closer to working now.
+
+t. A problem that caused the default filename used for mail checking to be
+ wrong was fixed.
+
+u. A fix was made to the `echo' builtin so that NUL characters printed with
+ `echo -e' do not cause the output to be truncated.
+
+v. A fix was made to the job control code so that the shell behaves better
+ when monitor mode is enabled in a non-interactive shell.
+
+w. Bash no longer catches all of the terminating signals in a non-
+ interactive shell until a trap is set on EXIT, which should result in
+ quicker startup.
+
+x. A fix was made to the command timing code so that `time' can be used in
+ a loop.
+
+y. A fix was made to the parser so that `((cmd); cmd2)' is now parsed as
+ a nested subshell rather than strictly as an (erroneous) arithmetic
+ command.
+
+z. A fix was made to the globbing code so that it correctly matches quoted
+ filenames beginning with a `.'.
+
+aa. A bug in `fc' that caused some multi-line commands to not be stored as
+ one command in the history when they were re-executed after editing
+ (with `fc -e') was fixed.
+
+bb. The `ulimit' builtin now attempts to catch some classes of integer
+ overflows.
+
+cc. 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
+ was fixed.
+
+ee. A bug that caused the shell to crash when an unset variable appeared
+ in the body of a here document after `set -u' had been executed was
+ fixed.
+
+ff. Implicit input redirections from /dev/null for asynchronous commands
+ are now handled better.
+
+gg. A bug that caused the shell to fail to compile when configured with
+ `--disable-readline' was fixed.
+
+hh. The globbing code should now be interruptible.
+
+ii. Bash now notices when the `kill' builtin is used to send SIGCONT to a
+ stopped job and adjusts the data structures accordingly, as if `bg' had
+ been executed instead.
+
+jj. A bug that caused the shell to crash when mixing calls to `getopts'
+ and `shift' on the same set of positional parameters was fixed.
+
+kk. The command printing code now preserves the `-p' flag to `time'.
+
+ll. The command printing code now handles here documents better when there
+ are other redirections associated with the command.
+
+mm. The special glibc environment variable (NNN_GNU_nonoption_argv_flags_)
+ is no longer placed into the environment of executed commands -- users
+ of glibc had too many problems with it.
+
+nn. Reorganized the code that generates signames.h. The signal_names list
+ is now more complete but may be slightly different (SIGABRT is favored
+ over SIGIOT, for example). The preferred signal names are those
+ listed in the POSIX.2 standard.
+
+oo. `bashbug' now uses a filename shorter than 14 characters for its
+ temporary file, and asks for confirmation before sending the bug
+ report.
+
+pp. A bug that caused TAB completion in vi editing mode to not be turned
+ off when `set -o posix' was executed or back on when `set +o posix'
+ was executed was fixed.
+
+qq. A bug in the brace expansion code that caused brace expansions appearing
+ in new-style $(...) command substitutions to be inappropriately expanded
+ was fixed.
+
+rr. A bug in the readline hook shell-expand-line that could cause memory to
+ be inappropriately freed was fixed.
+
+ss. A bug that caused some arithmetic expressions containing `&&' and `||'
+ to be parsed with the wrong precedence has been fixed.
+
+tt. References to unbound variables after `set -u' has been executed now
+ cause the shell to exit immediately, as they should.
+
+uu. A bug that caused the shell to exit inappropriately when `set -e' had
+ been executed and a command's return status was being inverted with the
+ `!' reserved word was fixed.
+
+vv. A bug that could occasionally cause the shell to crash with a
+ divide-by-zero error when timing a command was fixed.
+
+ww. A bug that caused parameter pattern substitution to leave stray
+ backslashes in the replacement string when the expression is in
+ double quotes was fixed.
+
+xx. The `break' and `continue' builtins now break out of all loops when an
+ invalid count argument is supplied.
+
+yy. Fixed a bug that caused PATH to be set to the empty string if
+ `command -p' is executed with PATH unset.
+
+zz. Fixed `kill -l signum' to print the signal name without the `SIG' prefix,
+ as POSIX specifies.
+
+aaa. Fixed a bug that caused the shell to crash while setting $SHELLOPTS
+ if there were no shell options set.
+
+bbb. Fixed `export -p' and `readonly -p' so that when the shell is in POSIX
+ mode, their output is as POSIX.2 specifies.
+
+ccc. Fixed a bug in `readonly' so that `readonly -a avar=(...)' actually
+ creates an array variable.
+
+ddd. Fixed a bug that prevented `time' from correctly timing background
+ pipelines.
+
+2. 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.

by a signal. Currently not called for SIGHUP or SIGTERM.
+
--- /dev/null
+This is a terse description of the new features added to bash-4.3 since
+the release of bash-4.2. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. The `helptopic' completion action now maps to all the help topics, not just
+ the shell builtins.
+
+b. The `help' builtin no longer does prefix substring matching, so `help read'
+ does not match `readonly'.
+
+c. The shell can be compiled to not display a message about processes that
+ terminate due to SIGTERM.
+
+d. Non-interactive shells now react to the setting of checkwinsize and set
+ LINES and COLUMNS after a foreground job exits.
+
+e. There is a new shell option, `globasciiranges', which, when set to on,
+ forces globbing range comparisons to use character ordering as if they
+ were run in the C locale.
+
+f. There is a new shell option, `direxpand', which makes filename completion
+ expand variables in directory names in the way bash-4.1 did.
+
+g. In Posix mode, the `command' builtin does not change whether or not a
+ builtin it shadows is treated as an assignment builtin.
+
+h. The `return' and `exit' builtins accept negative exit status arguments.
+
+i. The word completion code checks whether or not a filename containing a
+ shell variable expands to a directory name and appends `/' to the word
+ as appropriate. The same code expands shell variables in command names
+ when performing command completion.
+
+j. In Posix mode, it is now an error to attempt to define a shell function
+ with the same name as a Posix special builtin.
+
+k. When compiled for strict Posix conformance, history expansion is disabled
+ by default.
+
+l. The history expansion character (!) does not cause history expansion when
+ followed by the closing quote in a double-quoted string.
+
+m. `complete' and its siblings compgen/compopt now takes a new `-o noquote'
+ option to inhibit quoting of the completions.
+
+n. Setting HISTSIZE to a value less than zero causes the history list to be
+ unlimited (setting it 0 zero disables the history list).
+
+o. Setting HISTFILESIZE to a value less than zero causes the history file size
+ to be unlimited (setting it to 0 causes the history file to be truncated
+ to zero size).
+
+p. The `read' builtin now skips NUL bytes in the input.
+
+q. There is a new `bind -X' option to print all key sequences bound to Unix
+ commands.
+
+r. When in Posix mode, `read' is interruptible by a trapped signal. After
+ running the trap handler, read returns 128+signal and throws away any
+ partially-read input.
+
+s. The command completion code skips whitespace and assignment statements
+ before looking for the command name word to be completed.
+
+t. The build process has a new mechanism for constructing separate help files
+ that better reflects the current set of compilation options.
+
+u. The -nt and -ot options to test now work with files with nanosecond
+ timestamp resolution.
+
+v. The shell saves the command history in any shell for which history is
+ enabled and HISTFILE is set, not just interactive shells.
+
+w. The shell has `nameref' variables and new -n(/+n) options to declare and
+ unset to use them, and a `test -R' option to test for them.
+
+x. The shell now allows assigning, referencing, and unsetting elements of
+ indexed arrays using negative subscripts (a[-1]=2, echo ${a[-1]}) which
+ count back from the last element of the array.
+
+y. The {x}<word redirection feature now allows words like {array[ind]} and
+ can use variables with special meanings to the shell (e.g., BASH_XTRACEFD).
+
+z. There is a new CHILD_MAX special shell variable; its value controls the
+ number of exited child statues the shell remembers.
+
+aa. There is a new configuration option (--enable-direxpand-default) that
+ causes the `direxpand' shell option to be enabled by default.
+
+bb. Bash does not do anything special to ensure that the file descriptor
+ assigned to X in {x}<foo remains open after the block containing it
+ completes.
+
+cc. The `wait' builtin has a new `-n' option to wait for the next child to
+ change status.
+
+dd. The `printf' %(...)T format specifier now uses the current time if no
+ argument is supplied.
+
+ee. There is a new variable, BASH_COMPAT, that controls the current shell
+ compatibility level.
+
+ff. The `popd' builtin now treats additional arguments as errors.
+
+gg. The brace expansion code now treats a failed sequence expansion as a
+ simple string and will continue to expand brace terms in the remainder
+ of the word.
+
+hh. Shells started to run process substitutions now run any trap set on EXIT.
+
+2. New Features in Readline
+
+a. Readline is now more responsive to SIGHUP and other fatal signals when
+ reading input from the terminal or performing word completion but no
+ longer attempts to run any not-allowable functions from a signal handler
+ context.
+
+b. There are new bindable commands to search the history for the string of
+ characters between the beginning of the line and the point
+ (history-substring-search-forward, history-substring-search-backward)
+
+c. Readline allows quoted strings as the values of variables when setting
+ them with `set'. As a side effect, trailing spaces and tabs are ignored
+ when setting a string variable's value.
+
+d. The history library creates a backup of the history file when writing it
+ and restores the backup on a write error.
+
+e. New application-settable variable: rl_filename_stat_hook: a function called
+ with a filename before using it in a call to stat(2). Bash uses it to
+ expand shell variables so things like $HOME/Downloads have a slash
+ appended.
+
+f. New bindable function `print-last-kbd-macro', prints the most-recently-
+ defined keyboard macro in a reusable format.
+
+g. New user-settable variable `colored-stats', enables use of colored text
+ to denote file types when displaying possible completions (colored analog
+ of visible-stats).
+
+h. New user-settable variable `keyseq-timout', acts as an inter-character
+ timeout when reading input or incremental search strings.
+
+i. New application-callable function: rl_clear_history. Clears the history list
+ and frees all readline-associated private data.
+
+j. New user-settable variable, show-mode-in-prompt, adds a characters to the
+ beginning of the prompt indicating the current editing mode.
+
+k. New application-settable variable: rl_input_available_hook; function to be
+ called when readline detects there is data available on its input file
+ descriptor.
+
+l. Readline calls an application-set event hook (rl_event_hook) after it gets
+ a signal while reading input (read returns -1/EINTR but readline does not
+ handle the signal immediately) to allow the application to handle or
+ otherwise note it.
+
+m. If the user-settable variable `history-size' is set to a value less than
+ 0, the history list size is unlimited.
+
+n. New application-settable variable: rl_signal_event_hook; function that is
+ called when readline is reading terminal input and read(2) is interrupted
+ by a signal. Currently not called for SIGHUP or SIGTERM.
+
+-------------------------------------------------------------------------------
+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 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 and 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-
+ 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.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-4.1 since
+the release of bash-4.0. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. 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 if the compatibility level
+ is greater than 40.
+
+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.
+
+u. The read builtin has a new `-N nchars' option, which reads exactly NCHARS
+ characters, ignoring delimiters like newline.
+
+v. The mapfile/readarray builtin no longer stores the commands it invokes via
+ callbacks in the history list.
+
+w. There is a new `compat40' shopt option.
+
+2. 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.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-4.0 since
+the release of bash-3.2. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. 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. The name `readarray' is a synonym.
+
+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.
+
+ll. A value of 0 for the -t option to `read' now returns success if there is
+ input available to be read from the specified file descriptor.
+
+mm. CDPATH and GLOBIGNORE are ignored when the shell is running in privileged
+ mode.
+
+nn. New bindable readline functions shell-forward-word and shell-backward-word,
+ which move forward and backward words delimited by shell metacharacters
+ and honor shell quoting.
+
+oo. New bindable readline functions shell-backward-kill-word and shell-kill-word
+ which kill words backward and forward, but use the same word boundaries
+ as shell-forward-word and shell-backward-word.
+
+2. 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.
+
+j. If the kernel supports it, readline displays special characters
+ corresponding to a keyboard-generated signal when the signal is received.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-3.2 since
+the release of bash-3.1. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. 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.
+
+2. New Features in Readline
+
+a. Calling applications can now set the keyboard timeout to 0, allowing
+ poll-like behavior.
+
+b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
+ the default last-ditch startup file.
+
+c. The history file reading functions now allow windows-like \r\n line
+ terminators.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-3.1 since
+the release of bash-3.0. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. Bash now understands LC_TIME as a special variable so that time display
+ tracks the current locale.
+
+b. BASH_ARGC, BASH_ARGV, BASH_SOURCE, and BASH_LINENO are no longer created
+ as `invisible' variables and may not be unset.
+
+c. In POSIX mode, if `xpg_echo' option is enabled, the `echo' builtin doesn't
+ try to interpret any options at all, as POSIX requires.
+
+d. The `bg' builtin now accepts multiple arguments, as POSIX seems to specify.
+
+e. Fixed vi-mode word completion and glob expansion to perform tilde
+ expansion.
+
+f. The `**' mathematic exponentiation operator is now right-associative.
+
+g. The `ulimit' builtin has new options: -i (max number of pending signals),
+ -q (max size of POSIX message queues), and -x (max number of file locks).
+
+h. A bare `%' once again expands to the current job when used as a job
+ specifier.
+
+i. The `+=' assignment operator (append to the value of a string or array) is
+ now supported for assignment statements and arguments to builtin commands
+ that accept assignment statements.
+
+j. BASH_COMMAND now preserves its value when a DEBUG trap is executed.
+
+k. The `gnu_errfmt' option is enabled automatically if the shell is running
+ in an emacs terminal window.
+
+l. New configuration option: --single-help-strings. Causes long help text
+ to be written as a single string; intended to ease translation.
+
+m. The COMP_WORDBREAKS variable now causes the list of word break characters
+ to be emptied when the variable is unset.
+
+n. An unquoted expansion of $* when $IFS is empty now causes the positional
+ parameters to be concatenated if the expansion doesn't undergo word
+ splitting.
+
+o. Bash now inherits $_ from the environment if it appears there at startup.
+
+p. New shell option: nocasematch. If non-zero, shell pattern matching ignores
+ case when used by `case' and `[[' commands.
+
+q. The `printf' builtin takes a new option: -v var. That causes the output
+ to be placed into var instead of on stdout.
+
+r. By default, the shell no longer reports processes dying from SIGPIPE.
+
+s. Bash now sets the extern variable `environ' to the export environment it
+ creates, so C library functions that call getenv() (and can't use the
+ shell-provided replacement) get current values of environment variables.
+
+t. A new configuration option, `--enable-strict-posix-default', which will
+ build bash to be POSIX conforming by default.
+
+u. If compiled for strict POSIX conformance, LINES and COLUMNS may now
+ override the true terminal size.
+
+2. New Features in Readline
+
+a. The key sequence sent by the keypad `delete' key is now automatically
+ bound to delete-char.
+
+b. A negative argument to menu-complete now cycles backward through the
+ completion list.
+
+c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
+ readline will bind the terminal special characters to their readline
+ equivalents when it's called (on by default).
+
+d. New bindable command: vi-rubout. Saves deleted text for possible
+ reinsertion, as with any vi-mode `text modification' command; `X' is bound
+ to this in vi command mode.
+
+e. A new external application-controllable variable that allows the LINES
+ and COLUMNS environment variables to set the window size regardless of
+ what the kernel returns: rl_prefer_env_winsize
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-3.0 since
+the release of bash-2.05b. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. ANSI string expansion now implements the \x{hexdigits} escape.
+
+b. There is a new loadable `strftime' builtin.
+
+c. New variable, COMP_WORDBREAKS, which controls the readline completer's
+ idea of word break characters.
+
+d. The `type' builtin no longer reports on aliases unless alias expansion
+ will actually be performed.
+
+e. HISTCONTROL is now a colon-separated list of values, which permits
+ more extensibility and backwards compatibility.
+
+f. HISTCONTROL may now include the `erasedups' option, which causes all lines
+ matching a line being added to be removed from the history list.
+
+g. `configure' has a new `--enable-multibyte' argument that permits multibyte
+ character support to be disabled even on systems that support it.
+
+h. New variables to support the bash debugger: BASH_ARGC, BASH_ARGV,
+ BASH_SOURCE, BASH_LINENO, BASH_SUBSHELL, BASH_EXECUTION_STRING,
+ BASH_COMMAND
+
+i. FUNCNAME has been changed to support the debugger: it's now an array
+ variable.
+
+j. for, case, select, arithmetic commands now keep line number information
+ for the debugger.
+
+k. There is a new `RETURN' trap executed when a function or sourced script
+ returns (not inherited child processes; inherited by command substitution
+ if function tracing is enabled and the debugger is active).
+
+l. New invocation option: --debugger. Enables debugging and turns on new
+ `extdebug' shell option.
+
+m. New `functrace' and `errtrace' options to `set -o' cause DEBUG and ERR
+ traps, respectively, to be inherited by shell functions. Equivalent to
+ `set -T' and `set -E' respectively. The `functrace' option also controls
+ whether or not the DEBUG trap is inherited by sourced scripts.
+
+n. The DEBUG trap is run before binding the variable and running the action
+ list in a `for' command, binding the selection variable and running the
+ query in a `select' command, and before attempting a match in a `case'
+ command.
+
+o. New `--enable-debugger' option to `configure' to compile in the debugger
+ support code.
+
+p. `declare -F' now prints out extra line number and source file information
+ if the `extdebug' option is set.
+
+q. If `extdebug' is enabled, a non-zero return value from a DEBUG trap causes
+ the next command to be skipped, and a return value of 2 while in a
+ function or sourced script forces a `return'.
+
+r. New `caller' builtin to provide a call stack for the bash debugger.
+
+s. The DEBUG trap is run just before the first command in a function body is
+ executed, for the debugger.
+
+t. `for', `select', and `case' command heads are printed when `set -x' is
+ enabled.
+
+u. There is a new {x..y} brace expansion, which is shorthand for {x.x+1,
+ x+2,...,y}. x and y can be integers or single characters; the sequence
+ may ascend or descend; the increment is always 1.
+
+v. New ksh93-like ${!array[@]} expansion, expands to all the keys (indices)
+ of array.
+
+w. New `force_fignore' shopt option; if enabled, suffixes specified by
+ FIGNORE cause words to be ignored when performing word completion even
+ if they're the only possibilities.
+
+x. New `gnu_errfmt' shopt option; if enabled, error messages follow the `gnu
+ style' (filename:lineno:message) format.
+
+y. New `-o bashdefault' option to complete and compgen; if set, causes the
+ whole set of bash completions to be performed if the compspec doesn't
+ result in a match.
+
+z. New `-o plusdirs' option to complete and compgen; if set, causes directory
+ name completion to be performed and the results added to the rest of the
+ possible completions.
+
+aa. `kill' is available as a builtin even when the shell is built without
+ job control.
+
+bb. New HISTTIMEFORMAT variable; value is a format string to pass to
+ strftime(3). If set and not null, the `history' builtin prints out
+ timestamp information according to the specified format when displaying
+ history entries. If set, bash tells the history library to write out
+ timestamp information when the history file is written.
+
+cc. The [[ ... ]] command has a new binary `=~' operator that performs
+ extended regular expression (egrep-like) matching.
+
+dd. `configure' has a new `--enable-cond-regexp' option (enabled by default)
+ to enable the =~ operator and regexp matching in [[ ... ]].
+
+ee. Subexpressions matched by the =~ operator are placed in the new
+ BASH_REMATCH array variable.
+
+ff. New `failglob' option that causes an expansion error when pathname
+ expansion fails to produce a match.
+
+gg. New `set -o pipefail' option that causes a pipeline to return a failure
+ status if any of the processes in the pipeline fail, not just the last
+ one.
+
+hh. printf builtin understands two new escape sequences: \" and \?.
+
+ii. `echo -e' understands two new escape sequences: \" and \?.
+
+jj. The GNU `gettext' package and libintl have been integrated; the shell's
+ messages can be translated into different languages.
+
+kk. The `\W' prompt expansion now abbreviates $HOME as `~', like `\w'.
+
+ll. The error message printed when bash cannot open a shell script supplied
+ as argument 1 now includes the name of the shell, to better identify
+ the error as coming from bash.
+
+mm. The parameter pattern removal and substitution expansions are now much
+ faster and more efficient when using multibyte characters.
+
+nn. The `jobs', `kill', and `wait' builtins now accept job control notation
+ even if job control is not enabled.
+
+oo. The historical behavior of `trap' that allows a missing `action' argument
+ to cause each specified signal's handling to be reset to its default is
+ now only supported when `trap' is given a single non-option argument.
+
+2. New Features in Readline
+
+a. History expansion has a new `a' modifier equivalent to the `g' modifier
+ for compatibility with the BSD csh.
+
+b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
+ modifier, which performs a substitution once per word.
+
+c. All non-incremental search operations may now undo the operation of
+ replacing the current line with the history line.
+
+d. The text inserted by an `a' command in vi mode can be reinserted with
+ `.'.
+
+e. New bindable variable, `show-all-if-unmodified'. If set, the readline
+ completer will list possible completions immediately if there is more
+ than one completion and partial completion cannot be performed.
+
+f. There is a new application-callable `free_history_entry()' function.
+
+g. History list entries now contain timestamp information; the history file
+ functions know how to read and write timestamp information associated
+ with each entry.
+
+h. Four new key binding functions have been added:
+
+ rl_bind_key_if_unbound()
+ rl_bind_key_if_unbound_in_map()
+ rl_bind_keyseq_if_unbound()
+ rl_bind_keyseq_if_unbound_in_map()
+
+i. New application variable, rl_completion_quote_character, set to any
+ quote character readline finds before it calls the application completion
+ function.
+
+j. New application variable, rl_completion_suppress_quote, settable by an
+ application completion function. If set to non-zero, readline does not
+ attempt to append a closing quote to a completed word.
+
+k. New application variable, rl_completion_found_quote, set to a non-zero
+ value if readline determines that the word to be completed is quoted.
+ Set before readline calls any application completion function.
+
+l. New function hook, rl_completion_word_break_hook, called when readline
+ needs to break a line into words when completion is attempted. Allows
+ the word break characters to vary based on position in the line.
+
+m. New bindable command: unix-filename-rubout. Does the same thing as
+ unix-word-rubout, but adds `/' to the set of word delimiters.
+
+n. When listing completions, directories have a `/' appended if the
+ `mark-directories' option has been enabled.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05b since
+the release of bash-2.05a. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. If set, TMOUT is the default timeout for the `read' builtin.
+
+b. `type' has two new options: `-f' suppresses shell function lookup, and
+ `-P' forces a $PATH search.
+
+c. New code to handle multibyte characters.
+
+d. `select' was changed to be more ksh-compatible, in that the menu is
+ reprinted each time through the loop only if REPLY is set to NULL.
+ The previous behavior is available as a compile-time option.
+
+e. `complete -d' and `complete -o dirnames' now force a slash to be
+ appended to names which are symlinks to directories.
+
+f. There is now a bindable edit-and-execute-command readline command,
+ like the vi-mode `v' command, bound to C-xC-e in emacs mode.
+
+g. Added support for ksh93-like [:word:] character class in pattern matching.
+
+h. The $'...' quoting construct now expands \cX to Control-X.
+
+i. A new \D{...} prompt expansion; passes the `...' to strftime and inserts
+ the result into the expanded prompt.
+
+j. The shell now performs arithmetic in the largest integer size the
+ machine supports (intmax_t), instead of long.
+
+k. If a numeric argument is supplied to one of the bash globbing completion
+ functions, a `*' is appended to the word before expansion is attempted.
+
+l. The bash globbing completion functions now allow completions to be listed
+ with double tabs or if `show-all-if-ambiguous' is set.
+
+m. New `-o nospace' option for `complete' and `compgen' builtins; suppresses
+ readline's appending a space to the completed word.
+
+n. New `here-string' redirection operator: <<< word.
+
+o. When displaying variables, function attributes and definitions are shown
+ separately, allowing them to be re-used as input (attempting to re-use
+ the old output would result in syntax errors).
+
+p. There is a new configuration option `--enable-mem-scramble', controls
+ bash malloc behavior of writing garbage characters into memory at
+ allocation and free time.
+
+q. The `complete' and `compgen' builtins now have a new `-s/-A service'
+ option to complete on names from /etc/services.
+
+r. `read' has a new `-u fd' option to read from a specified file descriptor.
+
+s. Fix the completion code so that expansion errors in a directory name
+ don't cause a longjmp back to the command loop.
+
+t. Fixed word completion inside command substitution to work a little more
+ intuitively.
+
+u. The `printf' %q format specifier now uses $'...' quoting to print the
+ argument if it contains non-printing characters.
+
+v. The `declare' and `typeset' builtins have a new `-t' option. When applied
+ to functions, it causes the DEBUG trap to be inherited by the named
+ function. Currently has no effect on variables.
+
+w. The DEBUG trap is now run *before* simple commands, ((...)) commands,
+ [[...]] conditional commands, and for ((...)) loops.
+
+x. The expansion of $LINENO inside a shell function is only relative to the
+ function start if the shell is interactive -- if the shell is running a
+ script, $LINENO expands to the line number in the script. This is as
+ POSIX-2001 requires.
+
+y. The bash debugger in examples/bashdb has been modified to work with the
+ new DEBUG trap semantics, the command set has been made more gdb-like,
+ and the changes to $LINENO make debugging functions work better. Code
+ from Gary Vaughan.
+
+z. New [n]<&word- and [n]>&word- redirections from ksh93 -- move fds (dup
+ and close).
+
+aa. There is a new `-l' invocation option, equivalent to `--login'.
+
+bb. The `hash' builtin has a new `-l' option to list contents in a reusable
+ format, and a `-d' option to remove a name from the hash table.
+
+cc. There is now support for placing the long help text into separate files
+ installed into ${datadir}/bash. Not enabled by default; can be turned
+ on with `--enable-separate-helpfiles' option to configure.
+
+dd. All builtins that take operands accept a `--' pseudo-option, except
+ `echo'.
+
+ee. The `echo' builtin now accepts \0xxx (zero to three octal digits following
+ the `0') in addition to \xxx (one to three octal digits) for SUSv3/XPG6/
+ POSIX.1-2001 compliance.
+
+
+2. New Features in Readline
+
+a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both
+ be bound to readline functions. Now the arrow keys may be used in vi
+ insert mode.
+
+b. When listing completions, and the number of lines displayed is more than
+ the screen length, readline uses an internal pager to display the results.
+ This is controlled by the `page-completions' variable (default on).
+
+c. New code to handle editing and displaying multibyte characters.
+
+d. The behavior introduced in bash-2.05a of deciding whether or not to
+ append a slash to a completed name that is a symlink to a directory has
+ been made optional, controlled by the `mark-symlinked-directories'
+ variable (default is the 2.05a behavior).
+
+e. The `insert-comment' command now acts as a toggle if given a numeric
+ argument: if the first characters on the line don't specify a
+ comment, insert one; if they do, delete the comment text
+
+f. New application-settable completion variable:
+ rl_completion_mark_symlink_dirs, allows an application's completion
+ function to temporarily override the user's preference for appending
+ slashes to names which are symlinks to directories.
+
+g. New function available to application completion functions:
+ rl_completion_mode, to tell how the completion function was invoked
+ and decide which argument to supply to rl_complete_internal (to list
+ completions, etc.).
+
+h. Readline now has an overwrite mode, toggled by the `overwrite-mode'
+ bindable command, which could be bound to `Insert'.
+
+i. New application-settable completion variable:
+ rl_completion_suppress_append, inhibits appending of
+ rl_completion_append_character to completed words.
+
+j. New key bindings when reading an incremental search string: ^W yanks
+ the currently-matched word out of the current line into the search
+ string; ^Y yanks the rest of the current line into the search string,
+ DEL or ^H deletes characters from the search string.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05a since
+the release of bash-2.05. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. Added support for DESTDIR installation root prefix, so you can do a
+ `make install DESTDIR=bash-root' and do easier binary packaging.
+
+b. Added support for builtin printf "'" flag character as per latest POSIX
+ drafts.
+
+c. Support for POSIX.2 printf(1) length specifiers `j', `t', and `z' (from
+ ISO C99).
+
+d. New autoconf macro, RL_LIB_READLINE_VERSION, for use by other applications
+ (bash doesn't use very much of what it returns).
+
+e. `set [-+]o nolog' is recognized as required by the latest POSIX drafts,
+ but ignored.
+
+f. New read-only `shopt' option: login_shell. Set to non-zero value if the
+ shell is a login shell.
+
+g. New `\A' prompt string escape sequence; expands to time in 24 HH:MM format.
+
+h. New `-A group/-g' option to complete and compgen; does group name
+ completion.
+
+i. New `-t' option to `hash' to list hash values for each filename argument.
+
+j. New [-+]O invocation option to set and unset `shopt' options at startup.
+
+k. configure's `--with-installed-readline' option now takes an optional
+ `=PATH' suffix to set the root of the tree where readline is installed
+ to PATH.
+
+l. The ksh-like `ERR' trap has been added. The `ERR' trap will be run
+ whenever the shell would have exited if the -e option were enabled.
+ It is not inherited by shell functions.
+
+m. `readonly', `export', and `declare' now print variables which have been
+ given attributes but not set by assigning a value as just a command and
+ a variable name (like `export foo') when listing, as the latest POSIX
+ drafts require.
+
+n. `bashbug' now requires that the subject be changed from the default.
+
+o. configure has a new `--enable-largefile' option, like other GNU utilities.
+
+p. `for' loops now allow empty word lists after `in', like the latest POSIX
+ drafts require.
+
+q. The builtin `ulimit' now takes two new non-numeric arguments: `hard',
+ meaning the current hard limit, and `soft', meaning the current soft
+ limit, in addition to `unlimited'
+
+r. `ulimit' now prints the option letter associated with a particular
+ resource when printing more than one limit.
+
+s. `ulimit' prints `hard' or `soft' when a value is not `unlimited' but is
+ one of RLIM_SAVED_MAX or RLIM_SAVED_CUR, respectively.
+
+t. The `printf' builtin now handles the %a and %A conversions if they're
+ implemented by printf(3).
+
+u. The `printf' builtin now handles the %F conversion (just about like %f).
+
+v. The `printf' builtin now handles the %n conversion like printf(3). The
+ corresponding argument is the name of a shell variable to which the
+ value is assigned.
+
+2. New Features in Readline
+
+a. Added extern declaration for rl_get_termcap to readline.h, making it a
+ public function (it was always there, just not in readline.h).
+
+b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402,
+ RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d. New bindable boolean readline variable: match-hidden-files. Controls
+ completion of files beginning with a `.' (on Unix). Enabled by default.
+
+e. The history expansion code now allows any character to terminate a
+ `:first-' modifier, like csh.
+
+f. New bindable variable `history-preserve-point'. If set, the history
+ code attempts to place the user at the same location on each history
+ line retrived with previous-history or next-history.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05 since
+the release of bash-2.04. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. Added a new `--init-file' invocation argument as a synonym for `--rcfile',
+ per the new GNU coding standards.
+
+b. The /dev/tcp and /dev/udp redirections now accept service names as well as
+ port numbers.
+
+c. `complete' and `compgen' now take a `-o value' option, which controls some
+ of the aspects of that compspec. Valid values are:
+
+ default - perform bash default completion if programmable
+ completion produces no matches
+ dirnames - perform directory name completion if programmable
+ completion produces no matches
+ filenames - tell readline that the compspec produces filenames,
+ so it can do things like append slashes to
+ directory names and suppress trailing spaces
+
+d. A new loadable builtin, realpath, which canonicalizes and expands symlinks
+ in pathname arguments.
+
+e. When `set' is called without options, it prints function defintions in a
+ way that allows them to be reused as input. This affects `declare' and
+ `declare -p' as well. This only happens when the shell is not in POSIX
+ mode, since POSIX.2 forbids this behavior.
+
+f. Bash-2.05 once again honors the current locale setting when processing
+ ranges within pattern matching bracket expressions (e.g., [A-Z]).
+
+2. New Features in Readline
+
+a. The blink timeout for paren matching is now settable by applications,
+ via the rl_set_paren_blink_timeout() function.
+
+b. _rl_executing_macro has been renamed to rl_executing_macro, which means
+ it's now part of the public interface.
+
+c. Readline has a new variable, rl_readline_state, which is a bitmap that
+ encapsulates the current state of the library; intended for use by
+ callbacks and hook functions.
+
+d. New application-callable function rl_set_prompt(const char *prompt):
+ expands its prompt string argument and sets rl_prompt to the result.
+
+e. New application-callable function rl_set_screen_size(int rows, int cols):
+ public method for applications to set readline's idea of the screen
+ dimensions.
+
+f. New function, rl_get_screen_size (int *rows, int *columns), returns
+ readline's idea of the screen dimensions.
+
+g. The timeout in rl_gather_tyi (readline keyboard input polling function)
+ is now settable via a function (rl_set_keyboard_input_timeout()).
+
+h. Renamed the max_input_history variable to history_max_entries; the old
+ variable is maintained for backwards compatibility.
+
+i. The list of characters that separate words for the history tokenizer is
+ now settable with a variable: history_word_delimiters. The default
+ value is as before.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.04 since
+the release of bash-2.03. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. The history builtin has a `-d offset' option to delete the history entry
+ at position `offset'.
+
+b. The prompt expansion code has two new escape sequences: \j, the number of
+ active jobs; and \l, the basename of the shell's tty device name.
+
+c. The `bind' builtin has a new `-x' option to bind key sequences to shell
+ commands.
+
+d. There is a new shell option, no_empty_command_completion, which, when
+ enabled, disables command completion when TAB is typed on an empty line.
+
+e. The `help' builtin has a `-s' option to just print a builtin's usage
+ synopsis.
+
+f. There are several new arithmetic operators: id++, id-- (variable
+ post-increment/decrement), ++id, --id (variable pre-increment/decrement),
+ expr1 , expr2 (comma operator).
+
+g. There is a new ksh-93 style arithmetic for command:
+ for ((expr1 ; expr2; expr3 )); do list; done
+
+h. The `read' builtin has a number of new options:
+ -t timeout only wait timeout seconds for input
+ -n nchars only read nchars from input instead of a full line
+ -d delim read until delim rather than newline
+ -s don't echo input chars as they are read
+
+i. The redirection code now handles several filenames specially:
+ /dev/fd/N, /dev/stdin, /dev/stdout, and /dev/stderr, whether or
+ not they are present in the file system.
+
+j. The redirection code now recognizes pathnames of the form
+ /dev/tcp/host/port and /dev/udp/host/port, and tries to open a socket
+ of the appropriate type to the specified port on the specified host.
+
+k. The ksh-93 ${!prefix*} expansion, which expands to the names of all
+ shell variables with prefix PREFIX, has been implemented.
+
+l. There is a new dynamic variable, FUNCNAME, which expands to the name of
+ a currently-executing function. Assignments to FUNCNAME have no effect.
+
+m. The GROUPS variable is no longer readonly; assignments to it are silently
+ discarded. This means it can be unset.
+
+n. A new programmable completion facility, with two new builtin commands:
+ complete and compgen.
+
+o. configure has a new option, `--enable-progcomp', to compile in the
+ programmable completion features (enabled by default).
+
+p. `shopt' has a new option, `progcomp', to enable and disable programmable
+ completion at runtime.
+
+q. Unsetting HOSTFILE now clears the list of hostnames used for completion.
+
+r. configure has a new option, `--enable-bash-malloc', replacing the old
+ `--with-gnu-malloc' (which is still present for backwards compatibility).
+
+s. There is a new manual page describing rbash, the restricted shell.
+
+t. `bashbug' has new `--help' and `--version' options.
+
+u. `shopt' has a new `xpg_echo' option, which controls the behavior of
+ `echo' with respect to backslash-escaped characters at runtime.
+
+v. If NON_INTERACTIVE_LOGIN_SHELLS is defined, all login shells read the
+ startup files, even if they are not interactive.
+
+w. The LC_NUMERIC variable is now treated specially, and used to set the
+ LC_NUMERIC locale category for number formatting, e.g., when `printf'
+ displays floating-point numbers.
+
+2. New features in Readline
+
+a. Parentheses matching is now always compiled into readline, and enabled
+ or disabled when the value of the `blink-matching-paren' variable is
+ changed.
+
+b. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+c. MS-DOS systems now use ~/_history as the default history file.
+
+d. history-search-{forward,backward} now leave the point at the end of the
+ line when the string to search for is empty, like
+ {reverse,forward}-search-history.
+
+e. history-search-{forward,backward} now leave the last history line found
+ in the readline buffer if the second or subsequent search fails.
+
+f. New function for use by applications: rl_on_new_line_with_prompt, used
+ when an application displays the prompt itself before calling readline().
+
+g. New variable for use by applications: rl_already_prompted. An application
+ that displays the prompt itself before calling readline() must set this to
+ a non-zero value.
+
+h. A new variable, rl_gnu_readline_p, always 1. The intent is that an
+ application can verify whether or not it is linked with the `real'
+ readline library or some substitute.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.03 since
+the release of bash-2.02. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. New `shopt' option, `restricted_shell', indicating whether or not the
+ shell was started in restricted mode, for use in startup files.
+
+b. Filename generation is now performed on the words between ( and ) in
+ array assignments (which it probably should have done all along).
+
+c. OLDPWD is now auto-exported, as POSIX.2 seems to require.
+
+d. ENV and BASH_ENV are read-only variables in a restricted shell.
+
+e. A change was made to the startup file code so that any shell begun with
+ the `--login' option, even non-interactive shells, will source the login
+ shell startup files.
+
+2. New Features in Readline
+
+a. Many changes to the signal handling:
+ o Readline now catches SIGQUIT and cleans up the tty before returning;
+ o A new variable, rl_catch_signals, is available to application writers
+ to indicate to readline whether or not it should install its own
+ signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+ SIGTTIN, and SIGTTOU;
+ o A new variable, rl_catch_sigwinch, is available to application
+ writers to indicate to readline whether or not it should install its
+ own signal handler for SIGWINCH, which will chain to the calling
+ applications's SIGWINCH handler, if one is installed;
+ o There is a new function, rl_free_line_state, for application signal
+ handlers to call to free up the state associated with the current
+ line after receiving a signal;
+ o There is a new function, rl_cleanup_after_signal, to clean up the
+ display and terminal state after receiving a signal;
+ o There is a new function, rl_reset_after_signal, to reinitialize the
+ terminal and display state after an application signal handler
+ returns and readline continues
+
+b. There is a new function, rl_resize_terminal, to reset readline's idea of
+ the screen size after a SIGWINCH.
+
+c. New public functions: rl_save_prompt and rl_restore_prompt. These were
+ previously private functions with a `_' prefix.
+
+d. New function hook: rl_pre_input_hook, called just before readline starts
+ reading input, after initialization.
+
+e. New function hook: rl_display_matches_hook, called when readline would
+ display the list of completion matches. The new function
+ rl_display_match_list is what readline uses internally, and is available
+ for use by application functions called via this hook.
+
+f. New bindable function, delete-char-or-list, like tcsh.
+
+g. A new variable, rl_erase_empty_line, which, if set by an application using
+ readline, will cause readline to erase, prompt and all, lines on which the
+ only thing typed was a newline.
+
+h. New bindable variable: `isearch-terminators'.
+
+i. New bindable function: `forward-backward-delete-char' (unbound by default).
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.02 since
+the release of bash-2.01.1. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. A new version of malloc, based on the older GNU malloc, that has many
+ changes, is more page-based, is more conservative with memory usage,
+ and does not `orphan' large blocks when they are freed.
+
+b. A new version of gmalloc, based on the old GLIBC malloc, with many
+ changes and range checking included by default.
+
+c. A new implementation of fnmatch(3) that includes full POSIX.2 Basic
+ Regular Expression matching, including character classes, collating
+ symbols, equivalence classes, and support for case-insensitive pattern
+ matching.
+
+d. ksh-88 egrep-style extended pattern matching ([@+*?!](patlist)) has been
+ implemented, controlled by a new `shopt' option, `extglob'.
+
+e. There is a new ksh-like `[[' compound command, which implements
+ extended `test' functionality.
+
+f. There is a new `printf' builtin, implemented according to the POSIX.2
+ specification.
+
+g. There is a new feature for command substitution: $(< filename) now expands
+ to the contents of `filename', with any trailing newlines removed
+ (equivalent to $(cat filename)).
+
+h. There are new tilde prefixes which expand to directories from the
+ directory stack.
+
+i. There is a new `**' arithmetic operator to do exponentiation.
+
+j. There are new configuration options to control how bash is linked:
+ `--enable-profiling', to allow bash to be profiled with gprof, and
+ `--enable-static-link', to allow bash to be linked statically.
+
+k. There is a new configuration option, `--enable-cond-command', which
+ controls whether or not the `[[' command is included. It is on by
+ default.
+
+l. There is a new configuration option, `--enable-extended-glob', which
+ controls whether or not the ksh extended globbing feature is included.
+ It is enabled by default.
+
+m. There is a new configuration #define in config.h.top that, when enabled,
+ will cause all login shells to source /etc/profile and one of the user-
+ specific login shell startup files, whether or not the shell is
+ interactive.
+
+n. There is a new invocation option, `--dump-po-strings', to dump
+ a shell script's translatable strings ($"...") in GNU `po' format.
+
+o. There is a new `shopt' option, `nocaseglob', to enable case-insensitive
+ pattern matching when globbing filenames and using the `case' construct.
+
+p. There is a new `shopt' option, `huponexit', which, when enabled, causes
+ the shell to send SIGHUP to all jobs when an interactive login shell
+ exits.
+
+q. `bind' has a new `-u' option, which takes a readline function name as an
+ argument and unbinds all key sequences bound to that function in a
+ specified keymap.
+
+r. `disown' now has `-a' and `-r' options, to limit operation to all jobs
+ and running jobs, respectively.
+
+s. The `shopt' `-p' option now causes output to be displayed in a reusable
+ format.
+
+t. `test' has a new `-N' option, which returns true if the filename argument
+ has been modified since it was last accessed.
+
+u. `umask' now has a `-p' option to print output in a reusable format.
+
+v. A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...'
+ translation code. It expands to the character whose ascii code is NNN
+ in hexadecimal.
+
+w. The prompt string expansion code has a new `\r' escape sequence.
+
+x. The shell may now be cross-compiled for the CYGWIN32 environment on
+ a Unix machine.
+
+2. New Features in Readline
+
+a. There is now an option for `iterative' yank-last-arg handline, so a user
+ can keep entering `M-.', yanking the last argument of successive history
+ lines.
+
+b. New variable, `print-completions-horizontally', which causes completion
+ matches to be displayed across the screen (like `ls -x') rather than up
+ and down the screen (like `ls').
+
+c. New variable, `completion-ignore-case', which causes filename completion
+ and matching to be performed case-insensitively.
+
+d. There is a new bindable command, `magic-space', which causes history
+ expansion to be performed on the current readline buffer and a space to
+ be inserted into the result.
+
+e. There is a new bindable command, `menu-complete', which enables tcsh-like
+ menu completion (successive executions of menu-complete insert a single
+ completion match, cycling through the list of possible completions).
+
+f. There is a new bindable command, `paste-from-clipboard', for use on Win32
+ systems, to insert the text from the Win32 clipboard into the editing
+ buffer.
+
+g. The key sequence translation code now understands printf-style backslash
+ escape sequences, including \NNN octal escapes. These escape sequences
+ may be used in key sequence definitions or macro values.
+
+h. An `$include' inputrc file parser directive has been added.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.01 since
+the release of bash-2.0. As always, the manual page (doc/bash.1) is the
+place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. There is a new builtin array variable: GROUPS, the set of groups to which
+ the user belongs. This is used by the test suite.
+
+2. New Features in Readline
+
+a. If a key sequence bound to `universal-argument' is read while reading a
+ numeric argument started with `universal-argument', it terminates the
+ argument but is otherwise ignored. This provides a way to insert multiple
+ instances of a digit string, and is how GNU emacs does it.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.0 since
+the release of bash-1.14.7. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. There is a new invocation option, -D, that dumps translatable strings
+ in a script.
+
+b. The `long' invocation options must now be prefixed with `--'.
+
+c. New long invocation options: --dump-strings, --help, --verbose
+
+d. The `nolineediting' invocation option was renamed to `noediting'.
+
+e. The `nobraceexpansion' and `quiet' long invocation options were removed.
+
+f. The `--help' and `--version' long options now work as the GNU coding
+ standards specify.
+
+g. If invoked as `sh', bash now enters posix mode after reading the
+ startup files, and reads and executes commands from the file named
+ by $ENV if interactive (as POSIX.2 specifies). A login shell invoked
+ as `sh' reads $ENV after /etc/profile and ~/.profile.
+
+h. There is a new reserved word, `time', for timing pipelines, builtin
+ commands, and shell functions. It uses the value of the TIMEFORMAT
+ variable as a format string describing how to print the timing
+ statistics.
+
+i. The $'...' quoting syntax expands ANSI-C escapes in ... and leaves the
+ result single-quoted.
+
+j. The $"..." quoting syntax performs locale-specific translation of ...
+ and leaves the result double-quoted.
+
+k. LINENO now works correctly in functions.
+
+l. New variables: DIRSTACK, PIPESTATUS, BASH_VERSINFO, HOSTNAME, SHELLOPTS,
+ MACHTYPE. The first three are array variables.
+
+m. The BASH_VERSION and BASH_VERSINFO variables now include the shell's
+ `release status' (alpha[N], beta[N], release).
+
+n. Some variables have been removed: MAIL_WARNING, notify, history_control,
+ command_oriented_history, glob_dot_filenames, allow_null_glob_expansion,
+ nolinks, hostname_completion_file, noclobber, no_exit_on_failed_exec, and
+ cdable_vars. Most of them are now implemented with the new `shopt'
+ builtin; others were already implemented by `set'.
+
+o. Bash now uses some new variables: LC_ALL, LC_MESSAGES, LC_CTYPE,
+ LC_COLLATE, LANG, GLOBIGNORE, HISTIGNORE.
+
+p. The shell now supports integer-indexed arrays of unlimited length,
+ with a new compound assignment syntax and changes to the appropriate
+ builtin commands (declare/typeset, read, readonly, etc.). The array
+ index may be an arithmetic expression.
+
+q. ${!var}: indirect variable expansion, equivalent to eval \${$var}.
+
+r. ${paramter:offset[:length]}: variable substring extraction.
+
+s. ${parameter/pattern[/[/]string]}: variable pattern substitution.
+
+t. The $[...] arithmetic expansion syntax is no longer supported, in
+ favor of $((...)).
+
+u. Aliases can now be expanded in shell scripts with a shell option
+ (shopt expand_aliases).
+
+v. History and history expansion can now be used in scripts with
+ set -o history and set -H.
+
+w. All builtins now return an exit status of 2 for incorrect usage.
+
+x. Interactive shells resend SIGHUP to all running or stopped children
+ if (and only if) they exit due to a SIGHUP.
+
+y. New prompting expansions: \a, \e, \H, \T, \@, \v, \V.
+
+z. Variable expansion in prompt strings is now controllable via a shell
+ option (shopt promptvars).
+
+aa. Bash now defaults to using command-oriented history.
+
+bb. The history file ($HISTFILE) is now truncated to $HISTFILESIZE after
+ being written.
+
+cc. The POSIX.2 conditional arithmetic evaluation syntax (expr ? expr : expr)
+ has been implemented.
+
+dd. Each builtin now accepts `--' to signify the end of the options, except
+ as documented (echo, etc.).
+
+ee. All builtins use -p to display values in a re-readable format where
+ appropriate, except as documented (echo, type, etc.).
+
+ff. The `alias' builtin has a new -p option.
+
+gg. Changes to the `bind' builtin:
+ o has new options: -psPSVr.
+ o the `-d' option was renamed to `-p'
+ o the `-v' option now dumps variables; the old `-v' is now `-P'
+
+hh. The `bye' synonym for `exit' was removed.
+
+ii. The -L and -P options to `cd' and `pwd' have been documented.
+
+jj. The `cd' builtin now does spelling correction on the directory name
+ by default. This is settable with a shell option (shopt cdspell).
+
+kk. The `declare' builtin has new options: -a, -F, -p.
+
+ll. The `dirs' builtin has new options: -c, -p, -v.
+
+mm. The new `disown' builtin removes jobs from the shell's jobs table
+ or inhibits the resending of SIGHUP when the shell receives a
+ SIGHUP.
+
+nn. The `echo' builtin has a new escape character: \e.
+
+oo. The `enable' builtin can now load new builtins dynamically from shared
+ objects on systems with the dlopen/dlsym interface. There are a number
+ of examples in the examples/loadables directory. There are also
+ new options: -d, -f, -s, -p.
+
+pp. The `-all' option to `enable' was removed in favor of `-a'.
+
+qq. The `exec' builtin has new options: -l, -c, -a.
+
+rr. The `hash' builtin has a new option: -p.
+
+ss. The `history' builtin has new options: -c, -p, -s.
+
+tt. The `jobs' builtin has new options: -r, -s.
+
+uu. The `kill' builtin has new options: -n signum, -l signame.
+
+vv. The `pushd' and `popd' builtins have a new option: -n.
+
+ww. The `read' builtin has new options: -p prompt, -e, -a.
+
+xx. The `readonly' builtin has a new -a option, and the -n option was removed.
+
+yy. Changes to the `set' builtin:
+ o new options: -B, -o keyword, -o onecmd, -o history
+ o options removed: -l, -d, -o nohash
+ o options changed: +o, -h, -o hashall
+ o now displays variables in a format that can be re-read as input
+
+zz. The new `shopt' builtin controls shell optional behavior previously
+ done by setting and unsetting certain shell variables.
+
+aaa. The `test' builtin has new operators: -o option, s1 == s2, s1 < s2,
+ and s1 > s2, where s1 and s2 are strings.
+
+bbb. There is a new trap, DEBUG, executed after every simple command.
+
+ccc. The `trap' builtin has a new -p option.
+
+ddd. The `ulimit' builtin has a new -l option on 4.4BSD-based systems.
+
+eee. The PS1, PS2, PATH, and IFS variables may now be unset.
+
+fff. The restricted shell mode has been expanded and is now documented.
+
+ggg. Security improvements:
+ o functions are not imported from the environment if running setuid
+ or with -p
+ o no startup files are sourced if running setuid or with -p
+
+hhh. The documentation has been overhauled: the texinfo manual was
+ expanded, and HTML versions of the man page and texinfo manual
+ are included.
+
+iii. Changes to Posix mode:
+ o Command lookup now finds special builtins before shell functions.
+ o Failure of a special builtin causes a non-interactive shell to
+ exit. Failures are defined in the POSIX.2 specification.
+ o If the `cd' builtin finds a directory to change to using $CDPATH,
+ the value assigned to PWD when `cd' completes does not contain
+ any symbolic links.
+ o A non-interactive shell exits if a variable assignment error
+ occurs when no command name follows the assignment statements.
+ o A non-interactive shell exits if the interation variable in a
+ `for' statement or the selection variable in a `select' statement
+ is read-only or another variable assignment error occurs.
+ o The `<>' redirection operator now opens a file for both stdin and
+ stdout by default, not just when in posix mode.
+ o Assignment statements preceding special builtins now persist in
+ the shell's environment when the builtin completes.
+
+ Posix mode is now completely POSIX.2-compliant (modulo bugs). When
+ invoked as sh, bash should be completely POSIX.2-compliant.
+
+jjj. The default value of PS1 is now "\s-\v\$ ".
+
+kkk. The ksh-like ((...)) arithmetic command syntax has been implemented.
+ This is exactly equivalent to `let "..."'.
+
+lll. Integer constants have been extended to base 64.
+
+mmm. The `ulimit' builtin now sets both hard and soft limits and reports the
+ soft limit by default.
+
+2. New Features in Readline
+
+a. New variables: enable-keypad, input-meta (new name for meta-flag),
+ mark-directories, visible-stats (now documented), disable-completion,
+ comment-begin.
+
+b. New bindable commands: kill-region, copy-region-as-kill,
+ copy-backward-word, copy-forward-word, set-mark, exchange-point-and-mark,
+ character-search, character-search-backward, insert-comment,
+ glob-expand-word, glob-list-expansions, dump-variables, dump-macros.
+
+c. New emacs keybindings: delete-horizontal-space (M-\),
+ insert-completions (M-*), possible-completions (M-=).
+
+d. The history-search-backward and history-search-forward commands were
+ modified to be the same as previous-line and next-line if point is at
+ the start of the line.
+
+e. More file types are available for the visible-stats mode.
+
+3. Changes of interest in the Bash implementation
+
+a. There is a new autoconf-based configuration mechanism.
+
+b. More things have been moved from Posix mode to standard shell behavior.
+
+c. The trace output (set -x) now inserts quotes where necessary so it can
+ be reused as input.
+
+d. There is a compile-time option for a system-wide interactive shell
+ startup file (disabled by default).
+
+e. The YACC grammar is smaller and tighter, and all 66 shift-reduce
+ conflicts are gone. Several parsing bugs have been fixed.
+
+f. Builtin option parsing has been regularized (using internal_getopt()),
+ with the exception of `echo', `type', and `set'.
+
+g. Builtins now return standard usage messages constructed from the
+ `short doc' used by the help builtin.
+
+h. Completion now quotes using backslashes by default, but honors
+ user-supplied quotes.
+
+i. The GNU libc malloc is available as a configure-time option.
+
+j. There are more internationalization features; bash uses gettext if
+ it is available. The $"..." translation syntax uses the current
+ locale and gettext.
+
+k. There is better reporting of job termination when the shell is not
+ interactive.
+
+l. The shell is somewhat more efficient: it uses a little less memory and
+ makes fewer system calls.
+
+4. Changes of interest in the Readline implementation
+
+a. There is now support for readline `callback' functions.
+
+b. There is now support for user-supplied input, redisplay, and terminal
+ preparation functions.
+
+c. Most of the shell-specific code in readline has been generalized or
+ removed.
+
+d. Most of the annoying redisplay bugs have been fixed, notably the problems
+ with incremental search and excessive redrawing when special characters
+ appear in the prompt string.
+
+e. There are new library functions and variables available to application
+ writers, most having to do with completion and quoting.
+
+f. The NEWLINE character (^J) is now treated as a search terminator by the
+ incremental search functions.

+This is a terse description of the new features added to bash-4.3 since
+the release of bash-4.2. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. The `helptopic' completion action now maps to all the help topics, not just
+ the shell builtins.
+
+b. The `help' builtin no longer does prefix substring matching, so `help read'
+ does not match `readonly'.
+
+c. The shell can be compiled to not display a message about processes that
+ terminate due to SIGTERM.
+
+d. Non-interactive shells now react to the setting of checkwinsize and set
+ LINES and COLUMNS after a foreground job exits.
+
+e. There is a new shell option, `globasciiranges', which, when set to on,
+ forces globbing range comparisons to use character ordering as if they
+ were run in the C locale.
+
+f. There is a new shell option, `direxpand', which makes filename completion
+ expand variables in directory names in the way bash-4.1 did.
+
+g. In Posix mode, the `command' builtin does not change whether or not a
+ builtin it shadows is treated as an assignment builtin.
+
+h. The `return' and `exit' builtins accept negative exit status arguments.
+
+i. The word completion code checks whether or not a filename containing a
+ shell variable expands to a directory name and appends `/' to the word
+ as appropriate. The same code expands shell variables in command names
+ when performing command completion.
+
+j. In Posix mode, it is now an error to attempt to define a shell function
+ with the same name as a Posix special builtin.
+
+k. When compiled for strict Posix conformance, history expansion is disabled
+ by default.
+
+l. The history expansion character (!) does not cause history expansion when
+ followed by the closing quote in a double-quoted string.
+
+m. `complete' and its siblings compgen/compopt now takes a new `-o noquote'
+ option to inhibit quoting of the completions.
+
+n. Setting HISTSIZE to a value less than zero causes the history list to be
+ unlimited (setting it 0 zero disables the history list).
+
+o. Setting HISTFILESIZE to a value less than zero causes the history file size
+ to be unlimited (setting it to 0 causes the history file to be truncated
+ to zero size).
+
+p. The `read' builtin now skips NUL bytes in the input.
+
+q. There is a new `bind -X' option to print all key sequences bound to Unix
+ commands.
+
+r. When in Posix mode, `read' is interruptible by a trapped signal. After
+ running the trap handler, read returns 128+signal and throws away any
+ partially-read input.
+
+s. The command completion code skips whitespace and assignment statements
+ before looking for the command name word to be completed.
+
+t. The build process has a new mechanism for constructing separate help files
+ that better reflects the current set of compilation options.
+
+u. The -nt and -ot options to test now work with files with nanosecond
+ timestamp resolution.
+
+v. The shell saves the command history in any shell for which history is
+ enabled and HISTFILE is set, not just interactive shells.
+
+w. The shell has `nameref' variables and new -n(/+n) options to declare and
+ unset to use them, and a `test -R' option to test for them.
+
+x. The shell now allows assigning, referencing, and unsetting elements of
+ indexed arrays using negative subscripts (a[-1]=2, echo ${a[-1]}) which
+ count back from the last element of the array.
+
+y. The {x}<word redirection feature now allows words like {array[ind]} and
+ can use variables with special meanings to the shell (e.g., BASH_XTRACEFD).
+
+z. There is a new CHILD_MAX special shell variable; its value controls the
+ number of exited child statues the shell remembers.
+
+aa. There is a new configuration option (--enable-direxpand-default) that
+ causes the `direxpand' shell option to be enabled by default.
+
+bb. Bash does not do anything special to ensure that the file descriptor
+ assigned to X in {x}<foo remains open after the block containing it
+ completes.
+
+cc. The `wait' builtin has a new `-n' option to wait for the next child to
+ change status.
+
+dd. The `printf' %(...)T format specifier now uses the current time if no
+ argument is supplied.
+
+ee. There is a new variable, BASH_COMPAT, that controls the current shell
+ compatibility level.
+
+ff. The `popd' builtin now treats additional arguments as errors.
+
+gg. The brace expansion code now treats a failed sequence expansion as a
+ simple string and will continue to expand brace terms in the remainder
+ of the word.
+
+2. New Features in Readline
+
+a. Readline is now more responsive to SIGHUP and other fatal signals when
+ reading input from the terminal or performing word completion but no
+ longer attempts to run any not-allowable functions from a signal handler
+ context.
+
+b. There are new bindable commands to search the history for the string of
+ characters between the beginning of the line and the point
+ (history-substring-search-forward, history-substring-search-backward)
+
+c. Readline allows quoted strings as the values of variables when setting
+ them with `set'. As a side effect, trailing spaces and tabs are ignored
+ when setting a string variable's value.
+
+d. The history library creates a backup of the history file when writing it
+ and restores the backup on a write error.
+
+e. New application-settable variable: rl_filename_stat_hook: a function called
+ with a filename before using it in a call to stat(2). Bash uses it to
+ expand shell variables so things like $HOME/Downloads have a slash
+ appended.
+
+f. New bindable function `print-last-kbd-macro', prints the most-recently-
+ defined keyboard macro in a reusable format.
+
+g. New user-settable variable `colored-stats', enables use of colored text
+ to denote file types when displaying possible completions (colored analog
+ of visible-stats).
+
+h. New user-settable variable `keyseq-timout', acts as an inter-character
+ timeout when reading input or incremental search strings.
+
+i. New application-callable function: rl_clear_history. Clears the history list
+ and frees all readline-associated private data.
+
+j. New user-settable variable, show-mode-in-prompt, adds a characters to the
+ beginning of the prompt indicating the current editing mode.
+
+k. New application-settable variable: rl_input_available_hook; function to be
+ called when readline detects there is data available on its input file
+ descriptor.
+
+l. Readline calls an application-set event hook (rl_event_hook) after it gets
+ a signal while reading input (read returns -1/EINTR but readline does not
+ handle the signal immediately) to allow the application to handle or
+ otherwise note it.
+
+m. If the user-settable variable `history-size' is set to a value less than
+ 0, the history list size is unlimited.
+
+n. New application-settable variable: rl_signal_event_hook; function that is
+ called when readline is reading terminal input and read(2) is interrupted
+ by a signal. Currently not called for SIGHUP or SIGTERM.
+
+-------------------------------------------------------------------------------
+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 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 and 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-
+ 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.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-4.1 since
+the release of bash-4.0. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. 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 if the compatibility level
+ is greater than 40.
+
+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.
+
+u. The read builtin has a new `-N nchars' option, which reads exactly NCHARS
+ characters, ignoring delimiters like newline.
+
+v. The mapfile/readarray builtin no longer stores the commands it invokes via
+ callbacks in the history list.
+
+w. There is a new `compat40' shopt option.
+
+2. 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.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-4.0 since
+the release of bash-3.2. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. 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. The name `readarray' is a synonym.
+
+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.
+
+ll. A value of 0 for the -t option to `read' now returns success if there is
+ input available to be read from the specified file descriptor.
+
+mm. CDPATH and GLOBIGNORE are ignored when the shell is running in privileged
+ mode.
+
+nn. New bindable readline functions shell-forward-word and shell-backward-word,
+ which move forward and backward words delimited by shell metacharacters
+ and honor shell quoting.
+
+oo. New bindable readline functions shell-backward-kill-word and shell-kill-word
+ which kill words backward and forward, but use the same word boundaries
+ as shell-forward-word and shell-backward-word.
+
+2. 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.
+
+j. If the kernel supports it, readline displays special characters
+ corresponding to a keyboard-generated signal when the signal is received.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-3.2 since
+the release of bash-3.1. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. 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.
+
+2. New Features in Readline
+
+a. Calling applications can now set the keyboard timeout to 0, allowing
+ poll-like behavior.
+
+b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
+ the default last-ditch startup file.
+
+c. The history file reading functions now allow windows-like \r\n line
+ terminators.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-3.1 since
+the release of bash-3.0. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. Bash now understands LC_TIME as a special variable so that time display
+ tracks the current locale.
+
+b. BASH_ARGC, BASH_ARGV, BASH_SOURCE, and BASH_LINENO are no longer created
+ as `invisible' variables and may not be unset.
+
+c. In POSIX mode, if `xpg_echo' option is enabled, the `echo' builtin doesn't
+ try to interpret any options at all, as POSIX requires.
+
+d. The `bg' builtin now accepts multiple arguments, as POSIX seems to specify.
+
+e. Fixed vi-mode word completion and glob expansion to perform tilde
+ expansion.
+
+f. The `**' mathematic exponentiation operator is now right-associative.
+
+g. The `ulimit' builtin has new options: -i (max number of pending signals),
+ -q (max size of POSIX message queues), and -x (max number of file locks).
+
+h. A bare `%' once again expands to the current job when used as a job
+ specifier.
+
+i. The `+=' assignment operator (append to the value of a string or array) is
+ now supported for assignment statements and arguments to builtin commands
+ that accept assignment statements.
+
+j. BASH_COMMAND now preserves its value when a DEBUG trap is executed.
+
+k. The `gnu_errfmt' option is enabled automatically if the shell is running
+ in an emacs terminal window.
+
+l. New configuration option: --single-help-strings. Causes long help text
+ to be written as a single string; intended to ease translation.
+
+m. The COMP_WORDBREAKS variable now causes the list of word break characters
+ to be emptied when the variable is unset.
+
+n. An unquoted expansion of $* when $IFS is empty now causes the positional
+ parameters to be concatenated if the expansion doesn't undergo word
+ splitting.
+
+o. Bash now inherits $_ from the environment if it appears there at startup.
+
+p. New shell option: nocasematch. If non-zero, shell pattern matching ignores
+ case when used by `case' and `[[' commands.
+
+q. The `printf' builtin takes a new option: -v var. That causes the output
+ to be placed into var instead of on stdout.
+
+r. By default, the shell no longer reports processes dying from SIGPIPE.
+
+s. Bash now sets the extern variable `environ' to the export environment it
+ creates, so C library functions that call getenv() (and can't use the
+ shell-provided replacement) get current values of environment variables.
+
+t. A new configuration option, `--enable-strict-posix-default', which will
+ build bash to be POSIX conforming by default.
+
+u. If compiled for strict POSIX conformance, LINES and COLUMNS may now
+ override the true terminal size.
+
+2. New Features in Readline
+
+a. The key sequence sent by the keypad `delete' key is now automatically
+ bound to delete-char.
+
+b. A negative argument to menu-complete now cycles backward through the
+ completion list.
+
+c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
+ readline will bind the terminal special characters to their readline
+ equivalents when it's called (on by default).
+
+d. New bindable command: vi-rubout. Saves deleted text for possible
+ reinsertion, as with any vi-mode `text modification' command; `X' is bound
+ to this in vi command mode.
+
+e. A new external application-controllable variable that allows the LINES
+ and COLUMNS environment variables to set the window size regardless of
+ what the kernel returns: rl_prefer_env_winsize
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-3.0 since
+the release of bash-2.05b. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. ANSI string expansion now implements the \x{hexdigits} escape.
+
+b. There is a new loadable `strftime' builtin.
+
+c. New variable, COMP_WORDBREAKS, which controls the readline completer's
+ idea of word break characters.
+
+d. The `type' builtin no longer reports on aliases unless alias expansion
+ will actually be performed.
+
+e. HISTCONTROL is now a colon-separated list of values, which permits
+ more extensibility and backwards compatibility.
+
+f. HISTCONTROL may now include the `erasedups' option, which causes all lines
+ matching a line being added to be removed from the history list.
+
+g. `configure' has a new `--enable-multibyte' argument that permits multibyte
+ character support to be disabled even on systems that support it.
+
+h. New variables to support the bash debugger: BASH_ARGC, BASH_ARGV,
+ BASH_SOURCE, BASH_LINENO, BASH_SUBSHELL, BASH_EXECUTION_STRING,
+ BASH_COMMAND
+
+i. FUNCNAME has been changed to support the debugger: it's now an array
+ variable.
+
+j. for, case, select, arithmetic commands now keep line number information
+ for the debugger.
+
+k. There is a new `RETURN' trap executed when a function or sourced script
+ returns (not inherited child processes; inherited by command substitution
+ if function tracing is enabled and the debugger is active).
+
+l. New invocation option: --debugger. Enables debugging and turns on new
+ `extdebug' shell option.
+
+m. New `functrace' and `errtrace' options to `set -o' cause DEBUG and ERR
+ traps, respectively, to be inherited by shell functions. Equivalent to
+ `set -T' and `set -E' respectively. The `functrace' option also controls
+ whether or not the DEBUG trap is inherited by sourced scripts.
+
+n. The DEBUG trap is run before binding the variable and running the action
+ list in a `for' command, binding the selection variable and running the
+ query in a `select' command, and before attempting a match in a `case'
+ command.
+
+o. New `--enable-debugger' option to `configure' to compile in the debugger
+ support code.
+
+p. `declare -F' now prints out extra line number and source file information
+ if the `extdebug' option is set.
+
+q. If `extdebug' is enabled, a non-zero return value from a DEBUG trap causes
+ the next command to be skipped, and a return value of 2 while in a
+ function or sourced script forces a `return'.
+
+r. New `caller' builtin to provide a call stack for the bash debugger.
+
+s. The DEBUG trap is run just before the first command in a function body is
+ executed, for the debugger.
+
+t. `for', `select', and `case' command heads are printed when `set -x' is
+ enabled.
+
+u. There is a new {x..y} brace expansion, which is shorthand for {x.x+1,
+ x+2,...,y}. x and y can be integers or single characters; the sequence
+ may ascend or descend; the increment is always 1.
+
+v. New ksh93-like ${!array[@]} expansion, expands to all the keys (indices)
+ of array.
+
+w. New `force_fignore' shopt option; if enabled, suffixes specified by
+ FIGNORE cause words to be ignored when performing word completion even
+ if they're the only possibilities.
+
+x. New `gnu_errfmt' shopt option; if enabled, error messages follow the `gnu
+ style' (filename:lineno:message) format.
+
+y. New `-o bashdefault' option to complete and compgen; if set, causes the
+ whole set of bash completions to be performed if the compspec doesn't
+ result in a match.
+
+z. New `-o plusdirs' option to complete and compgen; if set, causes directory
+ name completion to be performed and the results added to the rest of the
+ possible completions.
+
+aa. `kill' is available as a builtin even when the shell is built without
+ job control.
+
+bb. New HISTTIMEFORMAT variable; value is a format string to pass to
+ strftime(3). If set and not null, the `history' builtin prints out
+ timestamp information according to the specified format when displaying
+ history entries. If set, bash tells the history library to write out
+ timestamp information when the history file is written.
+
+cc. The [[ ... ]] command has a new binary `=~' operator that performs
+ extended regular expression (egrep-like) matching.
+
+dd. `configure' has a new `--enable-cond-regexp' option (enabled by default)
+ to enable the =~ operator and regexp matching in [[ ... ]].
+
+ee. Subexpressions matched by the =~ operator are placed in the new
+ BASH_REMATCH array variable.
+
+ff. New `failglob' option that causes an expansion error when pathname
+ expansion fails to produce a match.
+
+gg. New `set -o pipefail' option that causes a pipeline to return a failure
+ status if any of the processes in the pipeline fail, not just the last
+ one.
+
+hh. printf builtin understands two new escape sequences: \" and \?.
+
+ii. `echo -e' understands two new escape sequences: \" and \?.
+
+jj. The GNU `gettext' package and libintl have been integrated; the shell's
+ messages can be translated into different languages.
+
+kk. The `\W' prompt expansion now abbreviates $HOME as `~', like `\w'.
+
+ll. The error message printed when bash cannot open a shell script supplied
+ as argument 1 now includes the name of the shell, to better identify
+ the error as coming from bash.
+
+mm. The parameter pattern removal and substitution expansions are now much
+ faster and more efficient when using multibyte characters.
+
+nn. The `jobs', `kill', and `wait' builtins now accept job control notation
+ even if job control is not enabled.
+
+oo. The historical behavior of `trap' that allows a missing `action' argument
+ to cause each specified signal's handling to be reset to its default is
+ now only supported when `trap' is given a single non-option argument.
+
+2. New Features in Readline
+
+a. History expansion has a new `a' modifier equivalent to the `g' modifier
+ for compatibility with the BSD csh.
+
+b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
+ modifier, which performs a substitution once per word.
+
+c. All non-incremental search operations may now undo the operation of
+ replacing the current line with the history line.
+
+d. The text inserted by an `a' command in vi mode can be reinserted with
+ `.'.
+
+e. New bindable variable, `show-all-if-unmodified'. If set, the readline
+ completer will list possible completions immediately if there is more
+ than one completion and partial completion cannot be performed.
+
+f. There is a new application-callable `free_history_entry()' function.
+
+g. History list entries now contain timestamp information; the history file
+ functions know how to read and write timestamp information associated
+ with each entry.
+
+h. Four new key binding functions have been added:
+
+ rl_bind_key_if_unbound()
+ rl_bind_key_if_unbound_in_map()
+ rl_bind_keyseq_if_unbound()
+ rl_bind_keyseq_if_unbound_in_map()
+
+i. New application variable, rl_completion_quote_character, set to any
+ quote character readline finds before it calls the application completion
+ function.
+
+j. New application variable, rl_completion_suppress_quote, settable by an
+ application completion function. If set to non-zero, readline does not
+ attempt to append a closing quote to a completed word.
+
+k. New application variable, rl_completion_found_quote, set to a non-zero
+ value if readline determines that the word to be completed is quoted.
+ Set before readline calls any application completion function.
+
+l. New function hook, rl_completion_word_break_hook, called when readline
+ needs to break a line into words when completion is attempted. Allows
+ the word break characters to vary based on position in the line.
+
+m. New bindable command: unix-filename-rubout. Does the same thing as
+ unix-word-rubout, but adds `/' to the set of word delimiters.
+
+n. When listing completions, directories have a `/' appended if the
+ `mark-directories' option has been enabled.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05b since
+the release of bash-2.05a. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. If set, TMOUT is the default timeout for the `read' builtin.
+
+b. `type' has two new options: `-f' suppresses shell function lookup, and
+ `-P' forces a $PATH search.
+
+c. New code to handle multibyte characters.
+
+d. `select' was changed to be more ksh-compatible, in that the menu is
+ reprinted each time through the loop only if REPLY is set to NULL.
+ The previous behavior is available as a compile-time option.
+
+e. `complete -d' and `complete -o dirnames' now force a slash to be
+ appended to names which are symlinks to directories.
+
+f. There is now a bindable edit-and-execute-command readline command,
+ like the vi-mode `v' command, bound to C-xC-e in emacs mode.
+
+g. Added support for ksh93-like [:word:] character class in pattern matching.
+
+h. The $'...' quoting construct now expands \cX to Control-X.
+
+i. A new \D{...} prompt expansion; passes the `...' to strftime and inserts
+ the result into the expanded prompt.
+
+j. The shell now performs arithmetic in the largest integer size the
+ machine supports (intmax_t), instead of long.
+
+k. If a numeric argument is supplied to one of the bash globbing completion
+ functions, a `*' is appended to the word before expansion is attempted.
+
+l. The bash globbing completion functions now allow completions to be listed
+ with double tabs or if `show-all-if-ambiguous' is set.
+
+m. New `-o nospace' option for `complete' and `compgen' builtins; suppresses
+ readline's appending a space to the completed word.
+
+n. New `here-string' redirection operator: <<< word.
+
+o. When displaying variables, function attributes and definitions are shown
+ separately, allowing them to be re-used as input (attempting to re-use
+ the old output would result in syntax errors).
+
+p. There is a new configuration option `--enable-mem-scramble', controls
+ bash malloc behavior of writing garbage characters into memory at
+ allocation and free time.
+
+q. The `complete' and `compgen' builtins now have a new `-s/-A service'
+ option to complete on names from /etc/services.
+
+r. `read' has a new `-u fd' option to read from a specified file descriptor.
+
+s. Fix the completion code so that expansion errors in a directory name
+ don't cause a longjmp back to the command loop.
+
+t. Fixed word completion inside command substitution to work a little more
+ intuitively.
+
+u. The `printf' %q format specifier now uses $'...' quoting to print the
+ argument if it contains non-printing characters.
+
+v. The `declare' and `typeset' builtins have a new `-t' option. When applied
+ to functions, it causes the DEBUG trap to be inherited by the named
+ function. Currently has no effect on variables.
+
+w. The DEBUG trap is now run *before* simple commands, ((...)) commands,
+ [[...]] conditional commands, and for ((...)) loops.
+
+x. The expansion of $LINENO inside a shell function is only relative to the
+ function start if the shell is interactive -- if the shell is running a
+ script, $LINENO expands to the line number in the script. This is as
+ POSIX-2001 requires.
+
+y. The bash debugger in examples/bashdb has been modified to work with the
+ new DEBUG trap semantics, the command set has been made more gdb-like,
+ and the changes to $LINENO make debugging functions work better. Code
+ from Gary Vaughan.
+
+z. New [n]<&word- and [n]>&word- redirections from ksh93 -- move fds (dup
+ and close).
+
+aa. There is a new `-l' invocation option, equivalent to `--login'.
+
+bb. The `hash' builtin has a new `-l' option to list contents in a reusable
+ format, and a `-d' option to remove a name from the hash table.
+
+cc. There is now support for placing the long help text into separate files
+ installed into ${datadir}/bash. Not enabled by default; can be turned
+ on with `--enable-separate-helpfiles' option to configure.
+
+dd. All builtins that take operands accept a `--' pseudo-option, except
+ `echo'.
+
+ee. The `echo' builtin now accepts \0xxx (zero to three octal digits following
+ the `0') in addition to \xxx (one to three octal digits) for SUSv3/XPG6/
+ POSIX.1-2001 compliance.
+
+
+2. New Features in Readline
+
+a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both
+ be bound to readline functions. Now the arrow keys may be used in vi
+ insert mode.
+
+b. When listing completions, and the number of lines displayed is more than
+ the screen length, readline uses an internal pager to display the results.
+ This is controlled by the `page-completions' variable (default on).
+
+c. New code to handle editing and displaying multibyte characters.
+
+d. The behavior introduced in bash-2.05a of deciding whether or not to
+ append a slash to a completed name that is a symlink to a directory has
+ been made optional, controlled by the `mark-symlinked-directories'
+ variable (default is the 2.05a behavior).
+
+e. The `insert-comment' command now acts as a toggle if given a numeric
+ argument: if the first characters on the line don't specify a
+ comment, insert one; if they do, delete the comment text
+
+f. New application-settable completion variable:
+ rl_completion_mark_symlink_dirs, allows an application's completion
+ function to temporarily override the user's preference for appending
+ slashes to names which are symlinks to directories.
+
+g. New function available to application completion functions:
+ rl_completion_mode, to tell how the completion function was invoked
+ and decide which argument to supply to rl_complete_internal (to list
+ completions, etc.).
+
+h. Readline now has an overwrite mode, toggled by the `overwrite-mode'
+ bindable command, which could be bound to `Insert'.
+
+i. New application-settable completion variable:
+ rl_completion_suppress_append, inhibits appending of
+ rl_completion_append_character to completed words.
+
+j. New key bindings when reading an incremental search string: ^W yanks
+ the currently-matched word out of the current line into the search
+ string; ^Y yanks the rest of the current line into the search string,
+ DEL or ^H deletes characters from the search string.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05a since
+the release of bash-2.05. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. Added support for DESTDIR installation root prefix, so you can do a
+ `make install DESTDIR=bash-root' and do easier binary packaging.
+
+b. Added support for builtin printf "'" flag character as per latest POSIX
+ drafts.
+
+c. Support for POSIX.2 printf(1) length specifiers `j', `t', and `z' (from
+ ISO C99).
+
+d. New autoconf macro, RL_LIB_READLINE_VERSION, for use by other applications
+ (bash doesn't use very much of what it returns).
+
+e. `set [-+]o nolog' is recognized as required by the latest POSIX drafts,
+ but ignored.
+
+f. New read-only `shopt' option: login_shell. Set to non-zero value if the
+ shell is a login shell.
+
+g. New `\A' prompt string escape sequence; expands to time in 24 HH:MM format.
+
+h. New `-A group/-g' option to complete and compgen; does group name
+ completion.
+
+i. New `-t' option to `hash' to list hash values for each filename argument.
+
+j. New [-+]O invocation option to set and unset `shopt' options at startup.
+
+k. configure's `--with-installed-readline' option now takes an optional
+ `=PATH' suffix to set the root of the tree where readline is installed
+ to PATH.
+
+l. The ksh-like `ERR' trap has been added. The `ERR' trap will be run
+ whenever the shell would have exited if the -e option were enabled.
+ It is not inherited by shell functions.
+
+m. `readonly', `export', and `declare' now print variables which have been
+ given attributes but not set by assigning a value as just a command and
+ a variable name (like `export foo') when listing, as the latest POSIX
+ drafts require.
+
+n. `bashbug' now requires that the subject be changed from the default.
+
+o. configure has a new `--enable-largefile' option, like other GNU utilities.
+
+p. `for' loops now allow empty word lists after `in', like the latest POSIX
+ drafts require.
+
+q. The builtin `ulimit' now takes two new non-numeric arguments: `hard',
+ meaning the current hard limit, and `soft', meaning the current soft
+ limit, in addition to `unlimited'
+
+r. `ulimit' now prints the option letter associated with a particular
+ resource when printing more than one limit.
+
+s. `ulimit' prints `hard' or `soft' when a value is not `unlimited' but is
+ one of RLIM_SAVED_MAX or RLIM_SAVED_CUR, respectively.
+
+t. The `printf' builtin now handles the %a and %A conversions if they're
+ implemented by printf(3).
+
+u. The `printf' builtin now handles the %F conversion (just about like %f).
+
+v. The `printf' builtin now handles the %n conversion like printf(3). The
+ corresponding argument is the name of a shell variable to which the
+ value is assigned.
+
+2. New Features in Readline
+
+a. Added extern declaration for rl_get_termcap to readline.h, making it a
+ public function (it was always there, just not in readline.h).
+
+b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402,
+ RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d. New bindable boolean readline variable: match-hidden-files. Controls
+ completion of files beginning with a `.' (on Unix). Enabled by default.
+
+e. The history expansion code now allows any character to terminate a
+ `:first-' modifier, like csh.
+
+f. New bindable variable `history-preserve-point'. If set, the history
+ code attempts to place the user at the same location on each history
+ line retrived with previous-history or next-history.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05 since
+the release of bash-2.04. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. Added a new `--init-file' invocation argument as a synonym for `--rcfile',
+ per the new GNU coding standards.
+
+b. The /dev/tcp and /dev/udp redirections now accept service names as well as
+ port numbers.
+
+c. `complete' and `compgen' now take a `-o value' option, which controls some
+ of the aspects of that compspec. Valid values are:
+
+ default - perform bash default completion if programmable
+ completion produces no matches
+ dirnames - perform directory name completion if programmable
+ completion produces no matches
+ filenames - tell readline that the compspec produces filenames,
+ so it can do things like append slashes to
+ directory names and suppress trailing spaces
+
+d. A new loadable builtin, realpath, which canonicalizes and expands symlinks
+ in pathname arguments.
+
+e. When `set' is called without options, it prints function defintions in a
+ way that allows them to be reused as input. This affects `declare' and
+ `declare -p' as well. This only happens when the shell is not in POSIX
+ mode, since POSIX.2 forbids this behavior.
+
+f. Bash-2.05 once again honors the current locale setting when processing
+ ranges within pattern matching bracket expressions (e.g., [A-Z]).
+
+2. New Features in Readline
+
+a. The blink timeout for paren matching is now settable by applications,
+ via the rl_set_paren_blink_timeout() function.
+
+b. _rl_executing_macro has been renamed to rl_executing_macro, which means
+ it's now part of the public interface.
+
+c. Readline has a new variable, rl_readline_state, which is a bitmap that
+ encapsulates the current state of the library; intended for use by
+ callbacks and hook functions.
+
+d. New application-callable function rl_set_prompt(const char *prompt):
+ expands its prompt string argument and sets rl_prompt to the result.
+
+e. New application-callable function rl_set_screen_size(int rows, int cols):
+ public method for applications to set readline's idea of the screen
+ dimensions.
+
+f. New function, rl_get_screen_size (int *rows, int *columns), returns
+ readline's idea of the screen dimensions.
+
+g. The timeout in rl_gather_tyi (readline keyboard input polling function)
+ is now settable via a function (rl_set_keyboard_input_timeout()).
+
+h. Renamed the max_input_history variable to history_max_entries; the old
+ variable is maintained for backwards compatibility.
+
+i. The list of characters that separate words for the history tokenizer is
+ now settable with a variable: history_word_delimiters. The default
+ value is as before.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.04 since
+the release of bash-2.03. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. The history builtin has a `-d offset' option to delete the history entry
+ at position `offset'.
+
+b. The prompt expansion code has two new escape sequences: \j, the number of
+ active jobs; and \l, the basename of the shell's tty device name.
+
+c. The `bind' builtin has a new `-x' option to bind key sequences to shell
+ commands.
+
+d. There is a new shell option, no_empty_command_completion, which, when
+ enabled, disables command completion when TAB is typed on an empty line.
+
+e. The `help' builtin has a `-s' option to just print a builtin's usage
+ synopsis.
+
+f. There are several new arithmetic operators: id++, id-- (variable
+ post-increment/decrement), ++id, --id (variable pre-increment/decrement),
+ expr1 , expr2 (comma operator).
+
+g. There is a new ksh-93 style arithmetic for command:
+ for ((expr1 ; expr2; expr3 )); do list; done
+
+h. The `read' builtin has a number of new options:
+ -t timeout only wait timeout seconds for input
+ -n nchars only read nchars from input instead of a full line
+ -d delim read until delim rather than newline
+ -s don't echo input chars as they are read
+
+i. The redirection code now handles several filenames specially:
+ /dev/fd/N, /dev/stdin, /dev/stdout, and /dev/stderr, whether or
+ not they are present in the file system.
+
+j. The redirection code now recognizes pathnames of the form
+ /dev/tcp/host/port and /dev/udp/host/port, and tries to open a socket
+ of the appropriate type to the specified port on the specified host.
+
+k. The ksh-93 ${!prefix*} expansion, which expands to the names of all
+ shell variables with prefix PREFIX, has been implemented.
+
+l. There is a new dynamic variable, FUNCNAME, which expands to the name of
+ a currently-executing function. Assignments to FUNCNAME have no effect.
+
+m. The GROUPS variable is no longer readonly; assignments to it are silently
+ discarded. This means it can be unset.
+
+n. A new programmable completion facility, with two new builtin commands:
+ complete and compgen.
+
+o. configure has a new option, `--enable-progcomp', to compile in the
+ programmable completion features (enabled by default).
+
+p. `shopt' has a new option, `progcomp', to enable and disable programmable
+ completion at runtime.
+
+q. Unsetting HOSTFILE now clears the list of hostnames used for completion.
+
+r. configure has a new option, `--enable-bash-malloc', replacing the old
+ `--with-gnu-malloc' (which is still present for backwards compatibility).
+
+s. There is a new manual page describing rbash, the restricted shell.
+
+t. `bashbug' has new `--help' and `--version' options.
+
+u. `shopt' has a new `xpg_echo' option, which controls the behavior of
+ `echo' with respect to backslash-escaped characters at runtime.
+
+v. If NON_INTERACTIVE_LOGIN_SHELLS is defined, all login shells read the
+ startup files, even if they are not interactive.
+
+w. The LC_NUMERIC variable is now treated specially, and used to set the
+ LC_NUMERIC locale category for number formatting, e.g., when `printf'
+ displays floating-point numbers.
+
+2. New features in Readline
+
+a. Parentheses matching is now always compiled into readline, and enabled
+ or disabled when the value of the `blink-matching-paren' variable is
+ changed.
+
+b. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+c. MS-DOS systems now use ~/_history as the default history file.
+
+d. history-search-{forward,backward} now leave the point at the end of the
+ line when the string to search for is empty, like
+ {reverse,forward}-search-history.
+
+e. history-search-{forward,backward} now leave the last history line found
+ in the readline buffer if the second or subsequent search fails.
+
+f. New function for use by applications: rl_on_new_line_with_prompt, used
+ when an application displays the prompt itself before calling readline().
+
+g. New variable for use by applications: rl_already_prompted. An application
+ that displays the prompt itself before calling readline() must set this to
+ a non-zero value.
+
+h. A new variable, rl_gnu_readline_p, always 1. The intent is that an
+ application can verify whether or not it is linked with the `real'
+ readline library or some substitute.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.03 since
+the release of bash-2.02. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. New `shopt' option, `restricted_shell', indicating whether or not the
+ shell was started in restricted mode, for use in startup files.
+
+b. Filename generation is now performed on the words between ( and ) in
+ array assignments (which it probably should have done all along).
+
+c. OLDPWD is now auto-exported, as POSIX.2 seems to require.
+
+d. ENV and BASH_ENV are read-only variables in a restricted shell.
+
+e. A change was made to the startup file code so that any shell begun with
+ the `--login' option, even non-interactive shells, will source the login
+ shell startup files.
+
+2. New Features in Readline
+
+a. Many changes to the signal handling:
+ o Readline now catches SIGQUIT and cleans up the tty before returning;
+ o A new variable, rl_catch_signals, is available to application writers
+ to indicate to readline whether or not it should install its own
+ signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+ SIGTTIN, and SIGTTOU;
+ o A new variable, rl_catch_sigwinch, is available to application
+ writers to indicate to readline whether or not it should install its
+ own signal handler for SIGWINCH, which will chain to the calling
+ applications's SIGWINCH handler, if one is installed;
+ o There is a new function, rl_free_line_state, for application signal
+ handlers to call to free up the state associated with the current
+ line after receiving a signal;
+ o There is a new function, rl_cleanup_after_signal, to clean up the
+ display and terminal state after receiving a signal;
+ o There is a new function, rl_reset_after_signal, to reinitialize the
+ terminal and display state after an application signal handler
+ returns and readline continues
+
+b. There is a new function, rl_resize_terminal, to reset readline's idea of
+ the screen size after a SIGWINCH.
+
+c. New public functions: rl_save_prompt and rl_restore_prompt. These were
+ previously private functions with a `_' prefix.
+
+d. New function hook: rl_pre_input_hook, called just before readline starts
+ reading input, after initialization.
+
+e. New function hook: rl_display_matches_hook, called when readline would
+ display the list of completion matches. The new function
+ rl_display_match_list is what readline uses internally, and is available
+ for use by application functions called via this hook.
+
+f. New bindable function, delete-char-or-list, like tcsh.
+
+g. A new variable, rl_erase_empty_line, which, if set by an application using
+ readline, will cause readline to erase, prompt and all, lines on which the
+ only thing typed was a newline.
+
+h. New bindable variable: `isearch-terminators'.
+
+i. New bindable function: `forward-backward-delete-char' (unbound by default).
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.02 since
+the release of bash-2.01.1. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. A new version of malloc, based on the older GNU malloc, that has many
+ changes, is more page-based, is more conservative with memory usage,
+ and does not `orphan' large blocks when they are freed.
+
+b. A new version of gmalloc, based on the old GLIBC malloc, with many
+ changes and range checking included by default.
+
+c. A new implementation of fnmatch(3) that includes full POSIX.2 Basic
+ Regular Expression matching, including character classes, collating
+ symbols, equivalence classes, and support for case-insensitive pattern
+ matching.
+
+d. ksh-88 egrep-style extended pattern matching ([@+*?!](patlist)) has been
+ implemented, controlled by a new `shopt' option, `extglob'.
+
+e. There is a new ksh-like `[[' compound command, which implements
+ extended `test' functionality.
+
+f. There is a new `printf' builtin, implemented according to the POSIX.2
+ specification.
+
+g. There is a new feature for command substitution: $(< filename) now expands
+ to the contents of `filename', with any trailing newlines removed
+ (equivalent to $(cat filename)).
+
+h. There are new tilde prefixes which expand to directories from the
+ directory stack.
+
+i. There is a new `**' arithmetic operator to do exponentiation.
+
+j. There are new configuration options to control how bash is linked:
+ `--enable-profiling', to allow bash to be profiled with gprof, and
+ `--enable-static-link', to allow bash to be linked statically.
+
+k. There is a new configuration option, `--enable-cond-command', which
+ controls whether or not the `[[' command is included. It is on by
+ default.
+
+l. There is a new configuration option, `--enable-extended-glob', which
+ controls whether or not the ksh extended globbing feature is included.
+ It is enabled by default.
+
+m. There is a new configuration #define in config.h.top that, when enabled,
+ will cause all login shells to source /etc/profile and one of the user-
+ specific login shell startup files, whether or not the shell is
+ interactive.
+
+n. There is a new invocation option, `--dump-po-strings', to dump
+ a shell script's translatable strings ($"...") in GNU `po' format.
+
+o. There is a new `shopt' option, `nocaseglob', to enable case-insensitive
+ pattern matching when globbing filenames and using the `case' construct.
+
+p. There is a new `shopt' option, `huponexit', which, when enabled, causes
+ the shell to send SIGHUP to all jobs when an interactive login shell
+ exits.
+
+q. `bind' has a new `-u' option, which takes a readline function name as an
+ argument and unbinds all key sequences bound to that function in a
+ specified keymap.
+
+r. `disown' now has `-a' and `-r' options, to limit operation to all jobs
+ and running jobs, respectively.
+
+s. The `shopt' `-p' option now causes output to be displayed in a reusable
+ format.
+
+t. `test' has a new `-N' option, which returns true if the filename argument
+ has been modified since it was last accessed.
+
+u. `umask' now has a `-p' option to print output in a reusable format.
+
+v. A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...'
+ translation code. It expands to the character whose ascii code is NNN
+ in hexadecimal.
+
+w. The prompt string expansion code has a new `\r' escape sequence.
+
+x. The shell may now be cross-compiled for the CYGWIN32 environment on
+ a Unix machine.
+
+2. New Features in Readline
+
+a. There is now an option for `iterative' yank-last-arg handline, so a user
+ can keep entering `M-.', yanking the last argument of successive history
+ lines.
+
+b. New variable, `print-completions-horizontally', which causes completion
+ matches to be displayed across the screen (like `ls -x') rather than up
+ and down the screen (like `ls').
+
+c. New variable, `completion-ignore-case', which causes filename completion
+ and matching to be performed case-insensitively.
+
+d. There is a new bindable command, `magic-space', which causes history
+ expansion to be performed on the current readline buffer and a space to
+ be inserted into the result.
+
+e. There is a new bindable command, `menu-complete', which enables tcsh-like
+ menu completion (successive executions of menu-complete insert a single
+ completion match, cycling through the list of possible completions).
+
+f. There is a new bindable command, `paste-from-clipboard', for use on Win32
+ systems, to insert the text from the Win32 clipboard into the editing
+ buffer.
+
+g. The key sequence translation code now understands printf-style backslash
+ escape sequences, including \NNN octal escapes. These escape sequences
+ may be used in key sequence definitions or macro values.
+
+h. An `$include' inputrc file parser directive has been added.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.01 since
+the release of bash-2.0. As always, the manual page (doc/bash.1) is the
+place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. There is a new builtin array variable: GROUPS, the set of groups to which
+ the user belongs. This is used by the test suite.
+
+2. New Features in Readline
+
+a. If a key sequence bound to `universal-argument' is read while reading a
+ numeric argument started with `universal-argument', it terminates the
+ argument but is otherwise ignored. This provides a way to insert multiple
+ instances of a digit string, and is how GNU emacs does it.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.0 since
+the release of bash-1.14.7. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. There is a new invocation option, -D, that dumps translatable strings
+ in a script.
+
+b. The `long' invocation options must now be prefixed with `--'.
+
+c. New long invocation options: --dump-strings, --help, --verbose
+
+d. The `nolineediting' invocation option was renamed to `noediting'.
+
+e. The `nobraceexpansion' and `quiet' long invocation options were removed.
+
+f. The `--help' and `--version' long options now work as the GNU coding
+ standards specify.
+
+g. If invoked as `sh', bash now enters posix mode after reading the
+ startup files, and reads and executes commands from the file named
+ by $ENV if interactive (as POSIX.2 specifies). A login shell invoked
+ as `sh' reads $ENV after /etc/profile and ~/.profile.
+
+h. There is a new reserved word, `time', for timing pipelines, builtin
+ commands, and shell functions. It uses the value of the TIMEFORMAT
+ variable as a format string describing how to print the timing
+ statistics.
+
+i. The $'...' quoting syntax expands ANSI-C escapes in ... and leaves the
+ result single-quoted.
+
+j. The $"..." quoting syntax performs locale-specific translation of ...
+ and leaves the result double-quoted.
+
+k. LINENO now works correctly in functions.
+
+l. New variables: DIRSTACK, PIPESTATUS, BASH_VERSINFO, HOSTNAME, SHELLOPTS,
+ MACHTYPE. The first three are array variables.
+
+m. The BASH_VERSION and BASH_VERSINFO variables now include the shell's
+ `release status' (alpha[N], beta[N], release).
+
+n. Some variables have been removed: MAIL_WARNING, notify, history_control,
+ command_oriented_history, glob_dot_filenames, allow_null_glob_expansion,
+ nolinks, hostname_completion_file, noclobber, no_exit_on_failed_exec, and
+ cdable_vars. Most of them are now implemented with the new `shopt'
+ builtin; others were already implemented by `set'.
+
+o. Bash now uses some new variables: LC_ALL, LC_MESSAGES, LC_CTYPE,
+ LC_COLLATE, LANG, GLOBIGNORE, HISTIGNORE.
+
+p. The shell now supports integer-indexed arrays of unlimited length,
+ with a new compound assignment syntax and changes to the appropriate
+ builtin commands (declare/typeset, read, readonly, etc.). The array
+ index may be an arithmetic expression.
+
+q. ${!var}: indirect variable expansion, equivalent to eval \${$var}.
+
+r. ${paramter:offset[:length]}: variable substring extraction.
+
+s. ${parameter/pattern[/[/]string]}: variable pattern substitution.
+
+t. The $[...] arithmetic expansion syntax is no longer supported, in
+ favor of $((...)).
+
+u. Aliases can now be expanded in shell scripts with a shell option
+ (shopt expand_aliases).
+
+v. History and history expansion can now be used in scripts with
+ set -o history and set -H.
+
+w. All builtins now return an exit status of 2 for incorrect usage.
+
+x. Interactive shells resend SIGHUP to all running or stopped children
+ if (and only if) they exit due to a SIGHUP.
+
+y. New prompting expansions: \a, \e, \H, \T, \@, \v, \V.
+
+z. Variable expansion in prompt strings is now controllable via a shell
+ option (shopt promptvars).
+
+aa. Bash now defaults to using command-oriented history.
+
+bb. The history file ($HISTFILE) is now truncated to $HISTFILESIZE after
+ being written.
+
+cc. The POSIX.2 conditional arithmetic evaluation syntax (expr ? expr : expr)
+ has been implemented.
+
+dd. Each builtin now accepts `--' to signify the end of the options, except
+ as documented (echo, etc.).
+
+ee. All builtins use -p to display values in a re-readable format where
+ appropriate, except as documented (echo, type, etc.).
+
+ff. The `alias' builtin has a new -p option.
+
+gg. Changes to the `bind' builtin:
+ o has new options: -psPSVr.
+ o the `-d' option was renamed to `-p'
+ o the `-v' option now dumps variables; the old `-v' is now `-P'
+
+hh. The `bye' synonym for `exit' was removed.
+
+ii. The -L and -P options to `cd' and `pwd' have been documented.
+
+jj. The `cd' builtin now does spelling correction on the directory name
+ by default. This is settable with a shell option (shopt cdspell).
+
+kk. The `declare' builtin has new options: -a, -F, -p.
+
+ll. The `dirs' builtin has new options: -c, -p, -v.
+
+mm. The new `disown' builtin removes jobs from the shell's jobs table
+ or inhibits the resending of SIGHUP when the shell receives a
+ SIGHUP.
+
+nn. The `echo' builtin has a new escape character: \e.
+
+oo. The `enable' builtin can now load new builtins dynamically from shared
+ objects on systems with the dlopen/dlsym interface. There are a number
+ of examples in the examples/loadables directory. There are also
+ new options: -d, -f, -s, -p.
+
+pp. The `-all' option to `enable' was removed in favor of `-a'.
+
+qq. The `exec' builtin has new options: -l, -c, -a.
+
+rr. The `hash' builtin has a new option: -p.
+
+ss. The `history' builtin has new options: -c, -p, -s.
+
+tt. The `jobs' builtin has new options: -r, -s.
+
+uu. The `kill' builtin has new options: -n signum, -l signame.
+
+vv. The `pushd' and `popd' builtins have a new option: -n.
+
+ww. The `read' builtin has new options: -p prompt, -e, -a.
+
+xx. The `readonly' builtin has a new -a option, and the -n option was removed.
+
+yy. Changes to the `set' builtin:
+ o new options: -B, -o keyword, -o onecmd, -o history
+ o options removed: -l, -d, -o nohash
+ o options changed: +o, -h, -o hashall
+ o now displays variables in a format that can be re-read as input
+
+zz. The new `shopt' builtin controls shell optional behavior previously
+ done by setting and unsetting certain shell variables.
+
+aaa. The `test' builtin has new operators: -o option, s1 == s2, s1 < s2,
+ and s1 > s2, where s1 and s2 are strings.
+
+bbb. There is a new trap, DEBUG, executed after every simple command.
+
+ccc. The `trap' builtin has a new -p option.
+
+ddd. The `ulimit' builtin has a new -l option on 4.4BSD-based systems.
+
+eee. The PS1, PS2, PATH, and IFS variables may now be unset.
+
+fff. The restricted shell mode has been expanded and is now documented.
+
+ggg. Security improvements:
+ o functions are not imported from the environment if running setuid
+ or with -p
+ o no startup files are sourced if running setuid or with -p
+
+hhh. The documentation has been overhauled: the texinfo manual was
+ expanded, and HTML versions of the man page and texinfo manual
+ are included.
+
+iii. Changes to Posix mode:
+ o Command lookup now finds special builtins before shell functions.
+ o Failure of a special builtin causes a non-interactive shell to
+ exit. Failures are defined in the POSIX.2 specification.
+ o If the `cd' builtin finds a directory to change to using $CDPATH,
+ the value assigned to PWD when `cd' completes does not contain
+ any symbolic links.
+ o A non-interactive shell exits if a variable assignment error
+ occurs when no command name follows the assignment statements.
+ o A non-interactive shell exits if the interation variable in a
+ `for' statement or the selection variable in a `select' statement
+ is read-only or another variable assignment error occurs.
+ o The `<>' redirection operator now opens a file for both stdin and
+ stdout by default, not just when in posix mode.
+ o Assignment statements preceding special builtins now persist in
+ the shell's environment when the builtin completes.
+
+ Posix mode is now completely POSIX.2-compliant (modulo bugs). When
+ invoked as sh, bash should be completely POSIX.2-compliant.
+
+jjj. The default value of PS1 is now "\s-\v\$ ".
+
+kkk. The ksh-like ((...)) arithmetic command syntax has been implemented.
+ This is exactly equivalent to `let "..."'.
+
+lll. Integer constants have been extended to base 64.
+
+mmm. The `ulimit' builtin now sets both hard and soft limits and reports the
+ soft limit by default.
+
+2. New Features in Readline
+
+a. New variables: enable-keypad, input-meta (new name for meta-flag),
+ mark-directories, visible-stats (now documented), disable-completion,
+ comment-begin.
+
+b. New bindable commands: kill-region, copy-region-as-kill,
+ copy-backward-word, copy-forward-word, set-mark, exchange-point-and-mark,
+ character-search, character-search-backward, insert-comment,
+ glob-expand-word, glob-list-expansions, dump-variables, dump-macros.
+
+c. New emacs keybindings: delete-horizontal-space (M-\),
+ insert-completions (M-*), possible-completions (M-=).
+
+d. The history-search-backward and history-search-forward commands were
+ modified to be the same as previous-line and next-line if point is at
+ the start of the line.
+
+e. More file types are available for the visible-stats mode.
+
+3. Changes of interest in the Bash implementation
+
+a. There is a new autoconf-based configuration mechanism.
+
+b. More things have been moved from Posix mode to standard shell behavior.
+
+c. The trace output (set -x) now inserts quotes where necessary so it can
+ be reused as input.
+
+d. There is a compile-time option for a system-wide interactive shell
+ startup file (disabled by default).
+
+e. The YACC grammar is smaller and tighter, and all 66 shift-reduce
+ conflicts are gone. Several parsing bugs have been fixed.
+
+f. Builtin option parsing has been regularized (using internal_getopt()),
+ with the exception of `echo', `type', and `set'.
+
+g. Builtins now return standard usage messages constructed from the
+ `short doc' used by the help builtin.
+
+h. Completion now quotes using backslashes by default, but honors
+ user-supplied quotes.
+
+i. The GNU libc malloc is available as a configure-time option.
+
+j. There are more internationalization features; bash uses gettext if
+ it is available. The $"..." translation syntax uses the current
+ locale and gettext.
+
+k. There is better reporting of job termination when the shell is not
+ interactive.
+
+l. The shell is somewhat more efficient: it uses a little less memory and
+ makes fewer system calls.
+
+4. Changes of interest in the Readline implementation
+
+a. There is now support for readline `callback' functions.
+
+b. There is now support for user-supplied input, redisplay, and terminal
+ preparation functions.
+
+c. Most of the shell-specific code in readline has been generalized or
+ removed.
+
+d. Most of the annoying redisplay bugs have been fixed, notably the problems
+ with incremental search and excessive redrawing when special characters
+ appear in the prompt string.
+
+e. There are new library functions and variables available to application
+ writers, most having to do with completion and quoting.
+
+f. The NEWLINE character (^J) is now treated as a search terminator by the
+ incremental search functions.
