Starting bash with the `-posix' command-line option or setting the variable
POSIXLY_CORRECT while bash is running will cause bash to conform more
closely to the Posix.2 standard by changing the behavior to match that
specified by Posix.2 in areas where the bash default differs.
The following list is what's changed when `posixly_correct' is enabled:
1. When a command in the hash table no longer exists, bash will re-search
$PATH to find the new location.
2. The >& redirection does not redirect stdout and stderr.
3. The message printed by the job control code and builtins when a job
exits with a non-zero status is `Done(status)'.
4. The <> redirection does not open a file for both stdin and stdout, but
rather opens it for read-write on fd 0.
5. Reserved words may not be aliased.
6. The Posix.2 PS1 and PS2 expansions of `!' -> history number and `!!' -> `!'
are enabled.
7. Interactive comments are enabled by default. (Note that this version has
them on by default anyway.)
8. The Posix.2 startup files are executed ($ENV) rather than the normal bash
files.
9. Tilde expansion is only performed on assignments preceding a command name,
rather than on all assignment statements on the line.
10. The default history file is ~/.sh_history (default value of $HISTFILE).
11. The output of `kill -l' prints all the signal names on a single line,
separated by spaces.
12. Non-interactive shells exit if `file' in `. file' is not found.
13. Redirection operators do not perform pathname expansion on the word
in the redirection unless the shell is interactive
14. Function names must be valid shell identifiers. That is, they may not
contain characters other than letters, digits, and underscores, and
may not start with a digit
There is other Posix.2 behavior that bash does not implement. Specifically:
1. There are no `special builtins' and `regular builtins'. All builtins
are equivalent. This means that:
o assignment statements affect the execution environment of all
builtins, not just special ones
o temporary assignments do not persist after Posix.2 special
builtins complete
o Functions are found before Posix.2 special builtins
o The shell does not exit upon errors while executing Posix.2
special builtins
2. $LINENO does not represent the line number of a command within a function
3. The arithmetic evaluator does not implement the `e ? e1 : e2' conditional
expression

Notes:
ISC 386 machines must compile test.c without -O. The resultant shell dumps
core when test is invoked.
There have been reports that SCO 3.2v4.2 requires -DPRGP_PIPE in SCO_CFLAGS,
and that it has too many -D defines for SCO's cc (rcc works).
Contents of this directory:
CWRU.chlog - my change log since the last release

6/2
---
lib/readline/readline.c
- fixed an off-by-one error in the kill ring reallocation code
in rl_kill_text
Makefile
- replaced instances of /bin/sh with $(SHELL)
Makefile, cpp-Makefile, documentation/Makefile
- added a working `uninstall' target
[1.14.0 FCS release made available for FTP]
6/3
---
README
- added note about building with gcc, same as in Makefile
documentation/Makefile
- some versions of make don't understand `$*' in a regular recipe;
replace with features.dvi in the recipe for features.ps
6/4
---
subst.c
- fix up the calls to string_extract_double_quoted and
string_extract_single_quoted in char_is_quoted so the initial
value of the index is *after* the opening quote character
- make sure we only return 1 from char_is_quoted if the index
into the string after a call to string_extract_double_quoted or
string_extract_single_quoted is *greater than* `eindex'
lib/readline/complete.c
- change the order and sense of the quoting tests in
rl_complete_internal so that the expensive char_is_quoted
is only called if `scan' actually is a word break character
shell.c
- fixed a typo in the test for a restricted shell
builtins/exec.def
- need to include flags.h
6/6
---
make_cmd.c
- make sure that we don't try to walk down a null command tree
in connect_async_list (tickled by `(command &) &')
- if a command has the CMD_WANT_SUBSHELL bit set in its flags,
don't even try to walk the command tree and move the `&';
just connect the command with a null command using `&'
execute_cmd.c
- make sure we don't try to reference a command struct without
first checking it (case '&')
6/7
---
machines.h
- fix a typo in the NeXT/i386 description; change the NeXT description
to #define HAVE_RESOURCE if not already defined rather than putting
-DHAVE_RESOURCE into the SYSDEP_CFLAGS
6/9
---
Makefile
- make sure all of the rules that reinvoke `make' have the
`-f bash-Makefile' before the assignment statements; some
versions of make like it that way
variables.c
- make sure that `interactive' is set to 0 before evaluating the
string containing an exported function obtained from the
environment, so that it does not try to execute PROMPT_COMMAND
(this may not be the best fix)
6/13
----
documentation/Makefile
- make sure all of the directories exist before trying to install
doc files into them
lib/readline/history.c
- add a missing O_TRUNC to the open call for writing in
history_truncate_file
trap.c
- run_interrupt_trap should only try to run the trap command if
the value is not IMPOSSIBLE_TRAP_HANDLER
Makefile
- add `realclean'
lib/readline/complete.c
- do the same kind of double-quoting a replacement string if the
user supplies the opening double quote as we would if we were
adding both quotes ourselves
variables.c
- fixed the variable initialization so that history_control/HISTCONTROL
can be inherited from a parent shell
INSTALL, README, cpp-Makefile, documentation/bash.1, documentation/readline.3
- ai.mit.edu -> prep.ai.mit.edu
shell.c
- fixed a problem with setting no_line_editing to the result of the
check for running inside emacs, thereby losing any value
initialized by the `-nolineediting' flag
cpp-Makefile
- `make distclean' will now remove the `installed-bash' link
print_cmd.c
- fixed a problem with undefined variables when HAVE_VARARGS_H is
not defined
6/14
----
lib/readline/history.c
- fixed an error in the csh history expansion code so that the
`-y' word designator now expands to `0-y' rather than `1-y'
lib/readline/isearch.c
- changed an absolute check for a character falling within the
ASCII 32-126 range (printable chars) with checks for CTRL_P
and META_CHAR and a check against the value RUBOUT
- changed a `break' to a `continue' so that the first non-matching
character in the search string does not cause the search to
end abruptly
- initialize prev_line_found to 0 at the top of rl_search_history
to avoid duplicate history lines being saved across searches
lib/readline/rltty.c
- consolidated repeated code for setting special characters into
`SET_SPECIAL' defines
lib/readline/readline.c
- include <sys/ioctl.h> if VSTATUS is defined
- add bindable command rl_tty_status (unbound by default)
lib/readline/funmap.c
- assign bindable command name `tty-status' to rl_tty_status
INSTALL
- add note about compiling with gcc, same text as README
lib/readline/display.c
- many changes and tweaks to make redisplay work better when the
prompt has invisible characters. These changes are non-optimal
in that the prompt is redrawn more than it needs to be, but
things are a hell of a lot better than they were
6/15
----
documentation/Makefile
- make a variable NROFF that people can set to `groff -Tascii' if
they don't have real nroff
- changed the suffix rules to use $<
support/bashbug.sh
- if rmail doesn't exist or fails, save the bug report in
~/dead.bashbug
execute_cmd.c
- in setup_async_signals, only ignore SIGINT and SIGQUIT if job
control is not active. If it is active and the job is restarted,
SIGINT remains ignored, and the now-foregrounded job is not
interruptible
subst.c
- fixed up a problem with char_is_quoted that caused backslash-
escaped characters to cause incorrect results
tests/run-dollars, tests/dollar-at.sh, tests/dollar-star.sh
- since the error messages produced by `cat' vary, changed `cat'
to `recho' and updated the correct answers file
machines.h
- fixes to CRAY_STACKSEG_END definitions for different versions of
Unicos on the YMP (from Bill Jones)
- Motorola SVR4 machines have getcwd() and should not undef
HAVE_GETCWD
- on hpux 9.x, don't try to link with -lPW if compiling with gcc
(for alloca)
parse.y
- an ugly fix for a compiler problem with structure assignment on
the cray
6/16
----
builtins/wait.def
- replaced a call to sscanf with a validity check using all_digits()
and a call to atoi, since a pid_t is not necessarily an int, and
the sscanf clobbered the stack frame on systems where it is shorter
than an int (e.g., SCO)
lib/readline/display.c
- since META_CHAR and the other macros only work with unsigned
chars, make rl_character_len convert its argument to an unsigned
char before testing it
documentation/Makefile
- use $(INSTALL_DATA) instead of $(CP) to install the man pages and
info files
cpp-Makefile
- use INSTALL_PROGRAM and INSTALL_DATA to install binaries and
documentation; pass both values to installs in subdirectories
6/18
----
builtins/ulimit.def
- compensate for systems which define RLIMIT_OFILE instead of
RLIMIT_NOFILE, or don't provide such a compatibility define
themselves
shell.c
- make maybe_execute_file check for directories and print an
appropriate error message, since it's doing an fstat anyway
support/mksysdefs
- added support for a `-s srcdir' option so it can find
cpp-Makefile if ansi-Makefile is to be created
Makefile
- call mksysdefs with -s $(srcdir)
jobs.c
- add the magic #undef lines to avoid redefinition warnings on
SunOS 4 only
6/20
----
cpp-Makefile
- install `bashbug' with `make install'
trap.c
- make sure that `interactive' is set to 0 when running trap
commands
builtins/umask.c
- fixed typo in usage error message
subst.c
- fix process_substitute to set subshell_environment
jobs.c, nojobs.c
- only mess with the terminal settings for an interactive shell
that is not in a subshell environment
6/21
----
lib/readline/history.h
- add extern declaration of history_get
builtins/fc.def
- make history replacement when using `r' or `fc -s' obey the
setting of HISTCONTROL
general.c
- in canonicalize_pathname, preserve a double // at the start
of an absolute pathname, since that means something special
for the network directory system
README, INSTALL
- updated information about submitting bug reports
lib/readline/vi_mode.c, lib/readline/isearch.c
- make sure unistd.h is included before rldefs.h, if
HAVE_UNISTD_H is defined
6/24
----
lib/readline/complete.c
- add `#' to the list of characters which cause a completed filename
to be quoted
execute_cmd.c
- be more careful about closing pipe file descriptors in do_piping;
don't want to have `dup2(i, i); close(i);' problem
lib/readline/{keymaps,readline}.h
- include local copies of include files if READLINE_LIBRARY is
defined, otherwise include the `official, installed' versions
using #include <readline/xxx.h>
lib/readline/*.c
- define READLINE_LIBRARY before including any files
- include only `local' copies of include files using #include "xxx.h"
rather than #include <readline/xxx.h>
6/26
----
execute_cmd.c
- check for clobbering the bash input stream before closing a file
descriptor due to an r_close_this redirection
lib/readline/history.c
- made history_expand inhibit history expansion if the history
expansion char is set to 0
lib/readline/chardefs.h
- moved savestring() definition to rldefs.h
- changed lowercase_p, uppercase_p, to_lower, to_upper defines to
use <ctype.h> macros rather than assume ASCII
lib/readline/bind.c, general.c, general.h
- use strcasecmp, strncasecmp instead of str[n]icmp if
HAVE_STRCASECMP is defined
cpp-Makefile
- pass -DHAVE_STRCASECMP to builds in the libraries, primarily
readline
machines.h
- add HAVE_STRCASECMP to the entries for BSD/386, NetBSD, FreeBSD,
and 4.4 BSD
builtins/hash.def
- add a fourth parameter to remember_filename, the initial value
of times_found (0 if we're just looking it up for `hash', 1
for the command execution code)
execute_cmd.c
- call remember_filename with an initial value of 1 for times_found
builtins/wait.def
- handle a null argument with an error message
builtins/common.c
- parse_and_execute now takes a third parameter: the value for
`interactive' while it is executing commands
bashline.c, jobs.c, parse.y, shell.c, subst.c, trap.c, variables.c
- set the new third argument to parse_and_execute appropriately
builtins/eval.def, builtins/fc.def, builtins/source.def
- set the new third argument to parse_and_execute appropriately
builtins/help.def
- changed a call to strnicmp to strncmp when trying to find what
to give help on; it seems more correct
6/27
----
machines.h
- cleaned up the SunOS section so it no longer relies on
HAVE_SHARED_LIBS being defined; it uses SunOS4 and SunOS5
instead
support/mksysdefs
- define SYSDEF to be SunOS4 or SunOS5 depending on the output
of uname rather than looking for ld.so
6/29
----
machines.h
- minor change to the ardent titan machine description
- move the ardent and stardent descriptions before the
mips riscos description
print_cmd.c
- ardent machines also need the extern declaration for printf
make_cmd.c
- connect_async_list should do its work only if the lists to be
backgrounded are connected with `;'. This makes `;' bind tighter
than `&', so only the last job in the list is backgrounded. All
other lists should have the entire thing put in the background
parse.y
- added a function `print_prompt' to take care of displaying the
prompt string if readline is not being used. This fixes problems
with the prompt being displayed before the status of completed
jobs is printed
6/30
----
builtins/fg_bg.def
- `fg' and `bg' now print error messages if invoked when job control
is disabled
lib/readline/rltty.c
- if not compiled into the shell, make get_tty_settings get and set
the window size. This noop stops the process if it is started in
the background
lib/readline/readline.c
- provide a function version of savestring, if not being compiled
into the shell, since the macro has been removed from the
`public' header files
lib/readline/readline.h
- provide all extern function declarations without checking whether
VI_MODE or PAREN_MATCHING are defined. It does not hurt to define
them if they are not used and not in the library, and other
applications using readline can't tell whether or not VI_MODE was
defined when the library was compiled anyway
7/1
---
machines.h
- add #undef HAVE_DIRENT_H to the ardent titan description
7/2
---
lib/readline/chardefs.h
- removed META_P define, renamed CTRL_P to CTRL_CHAR
lib/readline/bind.c, lib/readline/isearch.c
- changed instances of CTRL_P to CTRL_CHAR
lib/readline/search.c
- include <unistd.h> before rldefs.h, if HAVE_UNISTD_H is defined
lib/readline/readline.c
- declare PC, UP, and BC as extern rather than `local' to the
readline library
7/5
---
bashline.c
- implement command word completion inside of command substitution
with a new function: `command_subst_completion_function'
subst.c
- new function to help with command subst completion: unclosed_pair
lib/readline/complete.c
- new variable rl_filename_quoting_desired, which can be set to 0
to inhibit the quoting of filenames after completion
lib/readline/readline.h
- declare rl_filename_completion_desired and
rl_filename_quoting_desired
builtins/bind.def
- don't save the old value of rl_outstream before initializing
readline -- it saves garbage values and screws up readline
parse.y
- don't have private state telling whether or not readline has
been initialized -- use bash_readline_initialized like other
functions in bashline.c
lib/readline/readline.c
- make the default 8-bit behavior be based on whether LC_CTYPE is
defined and its value (accept iso-8859-1 or iso_8859_1)
7/6
---
variables.c
- fix up the declaration of getenv() for convex machines
7/7
---
lib/readline/readline.c
- fixed up typos in the declaration of `savestring'
lib/readline/history.c
- fixed an off-by-one error in the ADD_CHAR macro which caused one
extra character to be overwritten, causing the gnu malloc to abort
when that one character was at the end of an allocated block
- changed the ADD_STRING macro to avoid some unnecessary xreallocs
lib/readline/display.c
- fixed a problem with move_cursor_relative -- function now returns
immediately if it has nothing to do
- fixed another problem with displaying prompts with invisible chars
lib/readline/chardefs.h
- fixed the CTRL macro to be right (agree with the BSD kernel, for
example)
cpp-Makefile
- fixed typo in the `install' recipe
7/8
---
support/srcdir
- fixed to handle srcdir when it begins with ./ or ../ to handle
$(srcdir) being a relative path better
cpp-Makefile
- changed some include paths to $(BUILTIN_ABSSRC) when building in
`builtins' to handle $(srcdir) being a relative path
- change the `chmod' on bashbug to turn on read and execute for all
- added a couple of definitions to make it easier for a later
`configure' program
support/mksysdefs
- added a -i option to specify an alternate set of directories to
search for include files
lib/readline/bind.c
- in rl_read_init_file, when skipping whitespace at the start of
the line, decrement `i' so that we don't jump past the start
of the next line
machines.h
- SCOv4 has a `robust' opendir that checks that you're actually
opening a directory
7/11
----
lib/readline/complete.c
- make sure a word break character is unquoted before using it to
separate out the current word for completing
machines.h
- new machine description: NetBSD on motorola m68k machines like
the hp300
- undef HAVE_GETWD in the generic svr4 machine description, like
other svr4 descriptions
lib/readline/rltty.c
- make sure to fflush (rl_outstream) after toggling the setting
of the keypad and meta key
portbash/libc.sh
- add a test for OPENDIR_NOT_ROBUST
support/getcppsyms.c
- output __svr4__ if we find __uxps__ (this makes the Fujitsu port of
SVR4 to the sparc build OK)
7/12
----
lib/readline/display.c
- more display-related fixes when the prompt has invisible chars;
this time for screen updates when moving between screen lines
lib/readline/readline.c, lib/readline/display.c
- changes to make readline work with terminals that have auto-wrap
from Per Bothner (new function _rl_update_final, term_xn changes,
some efficiency speedups, new function space_to_eol)
7/13
----
lib/readline/display.c
- after moving up screen lines using term_up in _rl_move_vert, if
the new screen line is 0, _rl_last_c_pos needs to be adjusted
to take invisible characters into account. This was the source
of many bugs
7/14
----
documentation/Makefile
- change instances of `groff' to `${GROFF}', GROFF is set to
`groff' by default
general.c, variables.c
- moved `qsort_string_compare' from variables.c to general.c
general.h, variables.h
- moved declaration of `qsort_string_compare' from variables.h
to general.h
alias.c, lib/readline/funmap.c
- moved qsort auxiliary functions after their use and added
forward declarations to avoid warnings from ANSI C compilers
memalloc.h
- hpux_9 needs alloca declared as `extern void *' if __STDC__
is defined
support/mksysdefs
- removed HAVE_SHARED_LIBS entirely
- make a call to /bin/uname -X for SCO machines to avoid running
a different uname from the $PATH
machines.h
- new descriptions: Intel i860 running SVR4, Tahoe running 4.3 BSD
- changed descriptions: Mips/RiscOS, DG AViiON, unknown machine
jobs.c
- changes to how the shell handles foreground jobs dying of SIGINT:
an interactive shell using job control will no longer
act as if it received a SIGINT if the foreground job
dies from a SIGINT
a non-interactive shell or shell without job control tries
to differentiate between SIGINTs it has seen (in
wait_sigint_handler) and a foreground job dying of a SIGINT
not sent from the keyboard, and runs the normal SIGINT code
only in the former case
7/15
----
support/mksysdefs
- check for ${UNAME}${RELEASE} expanding to `SunOS4*' or `SunOS5*'
to set SYSDEF to SunOS4 or SunOS5, respectively. Apparently
this does not work for Solbourne
7/18
----
lib/readline/rltty.c
- if output is being flushed on termios systems, loop until the
FLUSHO bit is no longer set in the termios struct
support/mksysdefs
- added a -A flag to force creation of ansi-Makefile
machines.h
- new entry for Tandem machines running SVR3
7/19
----
lib/readline/rldefs.h
- include <termcap.h> if HAVE_TERMCAP_H is defined
- use <termio.h> stuff if HAVE_TERMIO_H is defined and _POSIX_VERSION
is not defined
lib/readline/rldefs.h, lib/readline/history.c
- include "config.h" if HAVE_CONFIG_H is defined
lib/readline/{rldefs.h,signals.c,readline.c}
- WINSIZE_IN_IOCTL_H -> GWINSZ_IN_SYS_IOCTL for compatibility with
other GNU programs
lib/readline/doc/Makefile
- fixed up to create the readline and history manuals in dvi and
ps format
lib/readline/Makefile
- changes inspired by the standalone readline-2.0 distribution
7/20
----
lib/readline/history.c
- new function, history_is_stifled (), returns history_stifled
- set history_state flags member in the history state functions
lib/readline/history.h
- reorganized the function declarations, added missing declarations
- history_stifled is no longer exported by the library
- added a `flags' member to the HISTORY_STATE structure
bashline.c
- use history_is_stifled () instead of history_stifled
lib/readline/readline.c, lib/readline/vi_mode.c
- filled in correct argument declarations for functions called via
keymaps (count, key)
lib/readline/complete.c
- efficiency improvement for compare_strings
7/21
----
examples/dirfuncs
- new directory functions from ksh book, contributed by
Ken Konecki (kenk@wfg.com)
machines.h
- hpux_8 and hpux_9 should both #undef HAVE_ALLOCA unless gcc is
being used
7/22
----
bashline.c
- fixed up command_word_completion_function so that filenames with
leading tildes are completed correctly
7/26
----
builtins/read.def
- if -r not given, make sure CTLESC is removed from input string
when reading \<newline>
lib/readline/readline.c
- new function bind_arrow_keys, which binds vt100/ansi arrow key
escape sequences after reading the termcap definition and the
inputrc file
- new function rl_yank_last_arg, which does what insert-last-arg
does in bash
lib/readline/emacs_keymap.c
- remove default bindings to rl_arrow_keys for M-[ and M-O
- rl_yank_last_arg is now bound to `M-.' and `M-_' in
emacs_meta_keymap
subst.c
- when performing process substitution on systems with /dev/fd,
make sure the child clears the slot in dev_fd_list it gets
from its parent so the file descriptor does not get closed
inappropriately if reallocated by, e.g., pipe(2)
bashline.c
- removed insert_last_arg and the calls to bind in to `M-.' and `M-_'.
`insert-last-argument' is now bound to rl_yank_last_arg for
backwards compatibility
lib/readline/funmap.c
- `yank-last-arg' is now a named command for rl_yank_last_arg
documentation/bash.1, documentation/readline.3
- add description of yank-last-arg as one of the readline user
commands
lib/readline/doc/rluser.texinfo
- added description of yank-last-arg
builtins/getopts.def
- fixed a typo in the int-to-string code computing the value to set
OPTIND to: had '\0' instead of '0'
- made getopts handle the case where there are more than 9 dollar
variables (where rest_of_args is non-null) correctly
7/28
----
lib/readline/display.c
- fixes to the display code for single-line-display in the presence
of prompts containing invisible characters
lib/readline/readline.c
- if we are using horizontal scrolling and we have term_xn, decrement
the screenwidth by 1, since we won't be doing any line wrapping
7/31
----
jobs.c
- new variable `freeze_jobs_list' to set when changes to the jobs
list or status of jobs in the list (other than calling something
like `jobs -n') are undesirable. This is set when execuing traps
on SIGCHLD
8/1
---
subst.c
- check that `~' is unquoted before performing tilde expansion in
an assignment statement
8/3
---
bracecomp.c
- keep brace completion from dumping core if there is only one
match
lib/readline/chardefs.h
- add a define for digit_p, which returns the value of isdigit()
lib/readline/readline.c
- added function equivalents for uppercase_p, lowercase_p, to_upper,
to_lower, pure_alphabetic, digit_p, and digit_value
- replaced calls to numeric () with calls to digit_p, removed
definition of numeric ()
lib/readline/history.c
- digit -> digit_p
lib/readline/vi_mode.c
- replaced uses of the `isletter' define to use pure_alphabetic
from chartypes.h
- replaced uses of `numeric' with calls to digit_p
- added do...while(0) to `exchange' define
8/4

- change the `Shell Command Line Options' section to `Invoking
Bash' to be closer to the GNU coding standards
8/5

builtins/read.def
- fixed up a memory leak and made behavior correct when no
variables given and backslash escaped at least one input char
- if we added CTLESC anywhere while reading the input string,
make sure we call dequote_string on each word of the input
before calling bind_variable with that string
subst.c
- made an efficiency improvement to dequote_string -- don't
do anything when we see CTLESC, just `continue' the loop
