e. Added a configure-time check for correctly-working asprintf/snprintf.
f. Fixed some problems with line number calculation and display when sourcing
a file in an interactive shell.
g. Fixed a bug that caused the shell to crash when using `declare -A foo=bar'.

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.
------------------------------------------------------------------------------
This document details the changes between this version, bash-4.1-beta,
and the previous version, bash-4.1-alpha.
1. Changes to Bash
a. Fixed a bug in mapfile that caused the shell to crash if it was passed the
name of an associative array.
b. Fixed a bug that caused the shell to incorrectly split case patterns if
they contained characters in $IFS.
c. Fixed a bug that caused the shell to set $? to the wrong value when using
a construct ending with a variable assignment with set -x enabled and PS4
containing a command substitution.
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.

Compatibility with previous versions
====================================

still the `standard' version for a few Linux distributions) and bash-2.x.

compat32 shell options.
42. Bash-4.0 changes the handling of the set -e option so that the shell exits
if a pipeline fails (and not just if the last command in the failing
pipeline is a simple command). This is not as Posix specifies. There is
work underway to update this portion of the standard; the bash-4.0
behavior attempts to capture the consensus at the time of release.
43. Bash-4.0 fixes a Posix mode bug that caused the . (source) builtin to
search the current directory for its filename argument, even if "." is
not in $PATH. Posix says that the shell shouldn't look in $PWD in this
case.
44. Bash-4.1 uses the current locale when comparing strings using the < and
> operators to the `[[' command. This can be reverted to the previous
behavior by setting one of the `compatNN' shopt options.
Shell Compatibility Level
=========================
Bash-4.0 introduced the concept of a `shell compatibility level', specified
as a set of options to the shopt builtin (compat31, compat32, compat40 at
this writing). There is only one current compatibility level -- each
option is mutually exclusive. This list does not mention behavior that is
standard for a particular version (e.g., setting compat32 means that quoting
the rhs of the regexp matching operator quotes special regexp characters in
the word, which is default behavior in bash-3.2 and above).
compat31 set
- the < and > operators to the [[ command do not consider the current
locale when comparing strings
- quoting the rhs of the regexp matching operator (=~) has no
special effect
compat32 set
- the < and > operators to the [[ command do not consider the current
locale when comparing strings
compat40 set
- the < and > operators to the [[ command do not consider the current
locale when comparing strings
- interrupting a command list such as "a ; b ; c" causes the execution
of the entire list to be aborted

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.

Apple ships inadequate dynamic libreadline and libhistory "replacements"
as standard libraries.
20. If you're on a system like SGI Irix, and you get an error about not
being able to refer to a dynamic symbol
(ld: non-dynamic relocations refer to dynamic symbol PC), add
-DNEED_EXTERN_PC to the LOCAL_CFLAGS variable in lib/readline/Makefile.in

42. The `ulimit' builtin uses a block size of 512 bytes for the `-c'
and `-f' options.
43. The arrival of `SIGCHLD' when a trap is set on `SIGCHLD' does not
interrupt the `wait' builtin and cause it to return immediately.
The trap command is run once for each child that exits.
There is other POSIX behavior that Bash does not implement by default
even when in POSIX mode. Specifically:

B1) What's new in version 4.1?
Bash-4.0 is the fourth major release of bash. There are numerous new features,
some experimental. Depending on community reception, the experimental
features will evolve.
Bash-4.1 is the first revision to the fourth major release of bash.
Bash-4.0 contains the following new features (see the manual page for
complete descriptions and the CHANGES and NEWS files in the bash-4.0
Bash-4.1 contains the following new features (see the manual page for
complete descriptions and the CHANGES and NEWS files in the bash-4.1
distribution):
o Here-documents within $(...) command substitutions may once more be
delimited by the closing right paren, instead of requiring a newline.
o Bash's file status checks (executable, readable, etc.) now take file
system ACLs into account on file systems that support them.
o Bash now passes environment variables with names that are not valid
shell variable names through into the environment passed to child
processes.
o 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.
o `printf -v' can now assign values to array indices.
o New `complete -E' and `compopt -E' options that work on the "empty"
completion: completion attempted on an empty command line.
o 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.
o When displaying associative arrays, subscripts are now quoted.
o 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.
o The [[ and (( commands are now subject to the setting of `set -e' and the
ERR trap.
o The source/. builtin now removes NUL bytes from the file before attempting
to parse commands.
o There is a new configuration option (in config-top.h) that forces bash to
forward all history entries to syslog.
o A new variable $BASHOPTS to export shell options settable using `shopt' to
child processes.
o 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.
o 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.
o The < and > operators to the [[ conditional command now do string
comparison according to the current locale.
o Programmable completion now uses the completion for `b' instead of `a'
when completion is attempted on a line like: a $(b c.
o Force extglob on temporarily when parsing the pattern argument to
the == and != operators to the [[ command, for compatibility.
o 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.
o The read builtin has a new `-N nchars' option, which reads exactly NCHARS
characters, ignoring delimiters like newline.
o The mapfile/readarray builtin no longer stores the commands it invokes via
callbacks in the history list.
o There is a new `compat40' shopt option.
o 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).
o New bindable readline function: menu-complete-backward.
o In the readline vi-mode insertion keymap, C-n is now bound to menu-complete
by default, and C-p to menu-complete-backward.
o When in readline 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.
o New bindable readline 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.
o New bindable readline 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.
o 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.
o New bindable readline variable: echo-control-characters. If enabled, and
the tty ECHOCTL bit is set, controls the echoing of characters
corresponding to keyboard-generated signals.
o New bindable readline 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.

E15) Tell me more about the shell compatibility level.
Bash-4.0 introduced the concept of a `shell compatibility level', specified
as a set of options to the shopt builtin (compat31, compat32, compat40 at
this writing). There is only one current compatibility level -- each
option is mutually exclusive. This list does not mention behavior that is
standard for a particular version (e.g., setting compat32 means that quoting
the rhs of the regexp matching operator quotes special regexp characters in
the word, which is default behavior in bash-3.2 and above).
compat31 set

locale when comparing strings
- quoting the rhs of the regexp matching operator (=~) has no
special effect

There is some support for dynamically modifying completions. This is
most useful when used in combination with a default completion speci-
fied with ccoommpplleettee --DD. It's possible for shell functions executed as
completion handlers to indicate that completion should be retried by
returning an exit status of 124. If a shell function returns 124, and
changes the compspec associated with the command on which completion is
being attempted (supplied as the first argument when the function is
executed), programmable completion restarts from the beginning, with an
attempt to find a compspec for that command. This allows a set of com-
pletions to be built dynamically as completion is attempted, rather
than being loaded all at once.
For instance, assuming that there is a library of compspecs, each kept
in a file corresponding to the name of the command, the following
default completion function would load completions dynamically:
_completion_loader()
{
. "/etc/bash_completion.d/$1.sh" >/dev/null 2>&1 && return 124

There is some support for dynamically modifying completions. This is
most useful when used in combination with a default completion specified
with @option{-D}. It's possible for shell functions executed as completion
handlers to indicate that completion should be retried by returning an
exit status of 124. If a shell function returns 124, and changes
the compspec associated with the command on which completion is being
attempted (supplied as the first argument when the function is executed),
programmable completion restarts from the beginning, with an
attempt to find a compspec for that command. This allows a set of
completions to be built dynamically as completion is attempted, rather than
being loaded all at once.
For instance, assuming that there is a library of compspecs, each kept in a
file corresponding to the name of the command, the following default
completion function would load completions dynamically:
