Let me know if you have any this time.
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 first, so
`help read' does not match `readonly', but will do it if exact string
matching fails.
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.
ii. The fc builtin now interprets -0 as the current command line.
jj. Completing directory names containing shell variables now adds a trailing
slash if the expanded result is a directory.
kk. `cd' has a new `-@' option to browse a file's extended attributes on
systems that support O_XATTR.
ll. The test/[/[[ `-v variable' binary operator now understands array
references.
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.
o. rl_change_environment: new application-settable variable that controls
whether or not Readline modifies the environment (currently readline
modifies only LINES and COLUMNS).

- [tg] Use new BAFH for hashing
* Fix build on Debian GNU/kFreeBSD 7.3
* Update MASTER_SITES
Changelog:
This is version 5.0.5 of the shell. This is a stable release.
There are minor new features as well as bug fixes since 5.0.2.
5.0.3 and 5.0.4 were short-lived releases with most of the features of
5.0.5 that were replaced owing to significant bugs.
Incompatibilities between 5.0.2 and 5.0.5
-----------------------------------------
The "zshaddhistory" hook mechanism documented in the zshmisc manual page
has been upgraded so that a hook returning status 2 causes a history
line to be saved on the internal history list but not written to the
history file. Previously any non-zero status return would cause
the line not to be saved on the history at all. It is recommended
to use status 1 for this (indeed most shell users would naturally do
so).
Upstream changes:
-----------------
=== v0.9.16 14/08/2013 ===
* Added support to login script. Thank you Laurent Debacker for the patch.

horrors of ISO C Undefined Behaviour which is allowed to delete all your
data
[tg] Unbreak “set -o” (list flags) in lksh on LP64 machines
[tg] Implement Emacs mode PgUp as Vi insert mode Cur↑ for Yofuh
[tg] Allow setting both “set -o sh” and “set -o posix”, if done in the

to fix segmentation fault just after invocation, at least on
NetBSD/amd64 6.1, which is reported as PR pkg/47917.
The problem was also reported by gcc (4.5.3) as:
main.c: In function 'main':
main.c:206:15: warning: assignment makes pointer from integer without a cast
At following location:
203 char *simplified;
....
206 simplified = canonicalize_file_name(current_wd);
to address issues with NetBSD-6(and earlier)'s fontconfig not being
new enough for pango.
While doing that, also bump freetype2 dependency to current pkgsrc
version.
Suggested by tron in PR 47882
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
Should patch the configure script to respect the environment setting
of CC_FOR_GETHOST (or CC_FOR_BUILD or something), but this is less
work and will do for now.
Patch it up to use compile-tests rather than run-tests in autoconf
for many of its tests (OS-independently). Teach it about the few
remaining properties for NetBSD in particular.
ok agc
* [tg] Make “set -x” print the commands run in escaped form

works around a bug in broken software such as GNU tar (really!)
* [tg] Correct and simplify list and categorisation of built-in commands as

Changelog:
Changes since 5.0.0
-------------------
Numeric constants encountered in mathematical expressions (but not other
contexts) can contain underscores as separators that will be ignored on
evaluation, as allowed in other scripting languages. For example,
0xFFFF_FFFF, or 3.141_592_654.
"functions -T" turns on tracing for the specified function(s) only,
similar to "functions -t" except that tracing is turned off for any
functions called from the specified one(s) that don't also have the -t
or -T flag.
In file completion, the recursive-files style can be set to an array of
patterns to match against "$PWD/". In any matched location, it is
possibly to complete files in arbitrarily deep subdirectories without
needing to type the directory prefix. See example in the zshcompsys
manual.
The _user_expand completer now allows expansion functions in the
user-expand files to return a string in REPLY that will be used to name
the set of expansions returned.
Adam Hoka and hugor.
fish is a user friendly command line shell for UNIX-like operating
systems, written mainly with interactive use in mind. It differs
from other shells in that it only provides as few commands as
built-ins as possible and has a daemon which allows it to have
shared variables and command-line history between shell instances.
It also features feature-rich tab-completion and has command-line
syntax highlighting.

don't read-uninitialized for \177 in a here-doc
A DEL (0177, dec 127) byte in a here-document would cause dash to
access uninitialized memory at the end of one of the syntax.c
tables,
since those tables are sized to accommodate a maximum index of
BASESYNTAX + 126. Make the generated tables one byte larger.
printf ':<<\\E\n\200y\nE'|./dash
* src/mksyntax.c (filltable): Use 258, not 257 as the size,
so that BASESYNTAX(=130) + 127 is a valid index.
(print): Likewise.
Don't emit explicit array dimension in declaration.
* Avoid compiler warnings on isdigit.
* Add another missing LC_COLLATE to mkbuiltins.
* Fix NUL termination in readcmd.
* Lookup PWD after going through CDPATH.

* Honor tab as IFS whitespace when splitting fields in readcmd.
* Do not truncate file for FROMTO redirection.
* Fix quoted pattern patch breakage.
* Fix incorrect savefd conversions.
* Fix dowait signal race.

* Allow newlines after var name in for statements.
* Use CHKNL to parse case statements.
* Update manual page to differentiate dash from ash.
a window when the new patch file wasn't committed, and there's no check
for "extra" lines in distinfo, so this clearly identifies the version
with the new patch file included.
This unbreaks at least one of AST/ksh packages.

This source and binary release cleans up a few reported
build problems in the 2009-05-01 release (which has been
removed). The release procedures have been adjusted to avoid
similar problems in the future. (The main problem is
synthesizing external non-ast environments to fully exercise
portions of the build system seen by outside users -- since
we use our stuff for everything, including packaging and
building, setting up an environment that has no ast
components leaking in can be non-trivial).

2009-05-01
This source release contains the official (and hopefully
final) ksh93t+ 2009-05-01, along with updates for the ast
commands and libraries. A lot of work went into cleaning up
the regression tests -- most regressions directly correspond
to unsupported native system features or buggy native system
interfaces that we felt should be fixed rather than worked around.
Of course we could be persuaded otherwise.

Yes -- a new release in only 3 months. This release contains
fixes and features that address the issues raised on the lists.
A summary of recent ksh93 changes:
1. Double precision floating point arithmetic with full C99
arithmetic support on systems that provide the C99
arithmetic functions. The numbers Inf and NaN can be
used in arithmetic expressions.
2. TAB-TAB completion generates a numbered list of
completions which the user can select.
3. Support for processing/handling multibyte locales (e.g.,
en_US.UTF-8, hi_IN.UTF-8, ja_JP.eucJP, zh_CN.GB18030,
zh_TW.BIG5 etc.) has been extensively revised, tested,
and is now supported even on the language level (e.g.
variable and function identifiers may contain locale
specific codeset characters).
4. /dev/(tcp|udp|sctp)/host/sevrice now handles IPv6
addresses on systems that provide getaddrinfo(3).
5. The ability to seek on a file by offset or content with
new redirection operators.
6. A new --showme option which allows portions of a script
to behave as if -x were specified while other parts
execute as usual. This simplifies the coding of make -n
style semantics at the script level by eliminating code
replication. In particular, io redirections are handled
by --showme.
7. The [[...]] operator =~ has been added which compares
the string to an extended regular expression rather than
== which compares against a shell pattern.
8. The printf(1) builtin has been extended to support the =
flag for centering a field. The # flag when used with
%d and %i provides values in units of thousands or 1024
respectively with an appropriate suffix added.
9. Example screenshots from joint work with the Solaris
ksh93 integration project are available here.

This release, almost a year from the last big release,
contains changes based on feedback from the { ast-users
ast-developers uwin-users uwin-developers } lists and the
ongoing ksh93-solaris integration project. Thanks to all
who helped. Our resolution this year is to increase release
frequency to keep internal and external source/binaries
more in sync. See the release change log for details:

This package will install tcsh in the /bin directory (not ${LOCALBASE}/bin).
DragonFly already has tcsh in the base system, so this package will replace
it with no ability to restore the system version. This is not desired.
shells/tcsh still works should there be any need for a pkgsrc version installed
at ${LOCALBASE}/bin.

Changes:
Improved error handling in POSIX emulation, ${NAME:OFFSET:LENGTH}
syntax supports negative LENGTHs, new parameter expansion flag
(g:opts:) which escapes sequences like the echo and print builtins,
the region_highlight array is now updated dynamically as the command
line is edited and the zsh/parameter module has a new array $usergroups
which contains the names of system groups.
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.
to trigger/signal a rebuild for the transition 5.10.1 -> 5.12.1.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.
sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!

* Corrected completion error when using "~/". Thanks to Piotr Minkina for
reporting this.
* Corrected the get_aliases function.
* Corrected interpretation of ~user. Thank you Adrien Urban for reporting
this.

Please use your system's tools to set a user's home directory.
It will be completely removed in the next version of lshell.
* Corrected shell variable and wildcards expansions when checking a command.
Thank you Adrien Urban for reporting this.
* Added possibility to allow/forbid scp upload/download using scp_upload
and scp_download variables.

variable. Thank you Jason Heiss for reporting this.
* Corrected traceback when aliases is not defined in configuration, and
command is sent over SSH. Thank you Jason Heiss for reporting this.
sorry) of 'b', 'e' and 'w' commands in vi editing, when confronted with
a '_' character - this patch makes tcsh consider '_' characters to be part
of the word.
1) osh globbing is now handled by the main osh process, allowing
(for example) `mkdir some_really_long_directory_name... ; cd
some*...' and globbing for other special built-in commands as well.
2) A new, osh history-file-support feature has been added to save
the user's command-line history to the user $h/.osh.history file
if/when this file exists upon shell invocation.
0.9.10
. Corrected minor bug in the aliases function that appeared in the
previous version. Thank you Piotr Minkina for reporting this.
0.9.9
. Added the possibility to configure introduction prompt.
. Replaced "joker" by "warnings" (more elegant)
. Possibility of limiting the history file size.
. Added lpath built-in command to list allowed and denied path.
Thanks to Adrien Urban.
. Corrected bug when using "~" was not parsed as "home directory" when
used in a command other than "cd". Thank you Adrien Urban finding
this.
. Corrected minor typo when warning for a forbidden path.
. If $(foo) is present in the line, check if foo is allowed before
executing the line. Thank you Adrien Urban for pointing this out!
. Added the possibility to list commands allowed to be executed using
sudo.
The new configuration field is sudo_commands.
. Added the clear(1) command as a built-in command.
. Added '$(' and '${' in the forbidden list by default in the
configuration
file.
. Now check the content of curly braces withariables '${}'. Thank you
Adrien Urban for reporting this.
. Added possibility to set history file name using history_file in the
configuration file.
. Corrected the bug when using '|', '&' or ';' over ssh. Over ssh
forbidden
characters refers now to the list provided in the "forbidden" field.
Thank you Jools Wills for reporting this!
. It now possible to use "&&" and "||" even if "&" and/or "|" are in the
forbidden list. In order to forbid them too, you must add them
explicitely in the forbidden list. Thank you Adrien Urban for this
suggestion.
. Fixed aliases bug that replaced part of commands rendering them
unusable.
e.g. aliasei:vim replaced the view command by vimew.
. Added a logrotate file for lshell log files.
. Corrected parsing of commands overssh to be checked by the same
function
used by the lshell CLI.
Thank you Adrien Urban for you security audit and excellent ideas!
0.9.8
. Major bug fix. lshell did not launch on python 2.4 and 2.5
(https://sourceforge.net/projects/lshell/forums/forum/778301/topic/347
4668)
. Added aliases for commands over SSH.
0.9.7
. Cleaned up the Python code
. Corrected crash when directory permission denied
(Closes: https://sourceforge.net/tracker/?func=detail&aid=2875374&grou
p_id=215792&atid=1035093)
. Added possibility to set the home_path option using the '%u' flag.
(e.g. '/var/chroot/%u' where '%u' will be replaced by the user's
username)
. Now replaces "~" by user's home directory.
0.9.6
. Major security fix. User had access to all files located in forbidden
directories
(Closes: https://sourceforge.net/tracker/?func=detail&aid=2838542&grou
p_id=215792&atid=1035093)
. Corrects RPM generation bug
(Closes: https://sourceforge.net/tracker/index.php?func=detail&aid=283
8283&group_id=215792&atid=1035093)
. lshell exits gracefully when user home directory doesn't exist
0.9.5
. Minor release
. Changed lshell's group from lshellg to lshell (this should not have
an impact on older installations)
. Minor typo correction in the lshell.py code
I am pleased to announce that tcsh-6.17 is now available; this is a mainly a
bug fix release with the exception of these three feature additions:
10. always save the whole command, not just the first 80 chars of it.
4. Add autoexpand=onlyhistory (Don Estabrook, m66)
3. Add history in loops (Laurence Darby, m48)
Please consult the Fixes files for a complete list of changes.
Some highlighted changes (for full details, see the ChangeLog):
The command "emulate <mode> -c ..." evaluates an expression in a given
emulation. The emulation is sticky for functions defined within the
expression.
The variable CORRECT_IGNORE gives a pattern that can be ignored
in spelling correction. CORRECT_IGNORE='_*' ignores completion functions.
The option POSIX_ALIASES improves compatibility of aliases with other
shells.
The variable ZSH_PATCHLEVEL can be used to test for unreleased versions of
the shell; it is present but less useful in released versions.
The variables ZLE_REMOVE_SUFFIX_CHARS and ZLE_SPACE_SUFFIX_CHARS allow more
control over the way automatically removed suffixes are treated in
completion.

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.
Changes:
1) This update fixes a compilation problem on AIX caused by not
wrapping WCOREDUMP(s) with #ifdef WCOREDUMP ... #endif.
2) General code cleanup and rechecking w/ splint(1) reduces
unnecessary code duplication and eases future maintenance.
3) This update adds the program name to osh diagnostics (e.g.,
"osh: syntax error") for the sake of user friendliness.

When using the ** globbing operator, bash will incorrectly add an extra
directory name when the preceding directory name ends with `*' or an empty
string when there is no preceding directory name.
If the prompt length exactly matches the screen width, and the prompt ends
with invisible characters, readline positions the cursor incorrectly.
When parsing case statements in command substitutions, the shell did not
note that a newline is a shell metacharacter and can legally be followed
by a reserved word (e.g., `esac').
When not in a locale supporting multibyte characters, readline will
occasionally not erase characters between the cursor position and the end
of the line when killing text backwards.
If a SIGWINCH arrives while bash is performing redisplay, multi-line prompts
are displayed incorrectly due to the display code being called recursively.
Using an external command as part of the DEBUG trap when job control is
enabled causes pipelines to misbehave. The problem has to do with process
groups assigned to the pipeline and terminal.
A missing include file results in an empty function definition and a no-op
when checking whether or not the window size has changed.
Adding a null line to a here-document (e.g., by hitting EOF) causes the
shell to dump core attempting to dereference the NULL pointer.
There are several problems with the handling of $LINENO in an ERR trap.
Deferring handling of signals which should cause the shell to terminate until
it is "safe" to run the handler functions does not work for some terminating
signals.
When the fc builtin is run in a command substitution from a shell with history
enabled, it does not correctly calculate the command on which to operate.
Though references to $@ when there are no positional parameters will now
cause the shell to exit if the `errexit' option has been enabled, constructs
such as ${@:-foo} should not cause an exit.
A case statement using the ;& pattern terminator followed immediately by
"esac" caused a core dump due to a null pointer dereference.
When using the new |& operator following a simple command with a redirection,
the redirection of stderr through the pipe was not performed under certain
circumstances.

OK'd by seb@
Since two people already asked for it, here's the package, but
maintainer is set to pkgsrc-users.
Bash is an sh-compatible shell that incorporates useful features from
the Korn shell (ksh) and C shell (csh). It is intended to conform to
the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard.
It offers functional improvements over sh for both programming and
interactive use; these include command line editing, unlimited size
command history, job control, shell functions and aliases, indexed
arrays of unlimited size, and integer arithmetic in any base from two
to sixty-four. In addition, most sh scripts can be run by Bash without
modification.
This package contains the outdated version 3 of bash.
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.
