|
|
|
|
|
Version 5.2.3
|
|
|
|
* bug fixes
|
|
* arrays: set -A and unset now unset whole array.

|
|
|
|
* new compile time option: DEFAULT_ENV - if defined, it names a file to
|
|
include if $ENV is not set.
|
|
|
|
* test -o option: if option starts with a !, the test is negated. The test
|
|
always fails if the option doesn't exist (so [ -o foo -o -o !foo ] is true
|
|
iff option foo exists).
|
|
|
|
* new option: set -o nohup (currently on by default) - if set, running jobs
|
|
are not kill -HUP'd when a login shell exits; if clear, they are. In
|
|
future, this will be clear by default (to act like at&t ksh) - if you don't
|
|
(won't) like this, add "[ -o !nohup ] && set -o nohup" to your .profile.

|
|
* configuration: look for clock_t in sys/times.h.
|
|
* configuration: use _SIGMAX, if available, for # of signals.
|
|
* SIGHUP now causes builtin read command to exit.
|
|
* wait builtin now returns whenever a trapped signal occurs as per POSIX.
|
|
|
|
* v command now works in vi; anchored searches now work in vi mode (/^ptrn);
|
|
multi-line commands displayed correctly by history.
|
|
|
|
* echo is now schizophrenic: accepts -n/-e/-E and backslash sequences.
|
|
|
|
* test -H file added (checks for context dependent files on HPs).
|
|
|
|
* set -o gmacs and markdirs honoured.
|
|
|
|
* ansi arrow keys in default emacs key bindings.
|
|
|
|
* ulimit now takes arithmetic expression (as per Korn book).
|
|
|
|
* co-processes changed to be more compatible with at&t ksh.
|
|
|
|
Version 5.0.9
|
|
|
|
* bug fixes
|
|
* FOO is put in the environment for FOO=bar exec blah.
|
|
* compiles under QNX and with dmake.
|
|
* the file pattern [!a--]* is now invalid (POSIX) (used to match everything)
|
|
* echo "${foo:-"a"}*" no longer the same as echo a*.
|
|
* alternation (brace expansion) fixes:
|
|
* brace expansion done after variable expansion, as in csh/at&t ksh.
|
|
* `echo a{b,c' no longer gives "Missing }" error (it echos a{b,c).
|
|
* expansion only done if there is a comma (ie, `echo {a}' prints {a}).
|
|
* globbing/expansion code passes 0x80 unharmed.
|
|
* "echo ${XX=a*b}" no longer sets XX to "a\200*b".
|
|
* "echo ${unset-a*b}" no longer has \200 in the error message.
|
|
* bad substitution error generated for things like ${x:a}, ${x^a}, etc.
|
|
* `x="a cdef"; echo ${x#a c}' now prints "def" instead of "a a cdef".
|
|
* on systems where /etc/passwd//// is a valid name, echo /etc/pass*/ no
|
|
longer matches /etc/passwd.
|
|
* trace output (set -x) flushed correctly, PS4 initialized.
|
|
* ulimit output ungarbled, code to use {set,get}ulimit (if available)
|
|
enabled.
|
|
* tilde expansion done in word part of ${foo-~/bar}
|
|
* when reading stdin (ie, ksh -s), no longer reads too much.
|
|
* shell handles i/o redirection and errors in builtin commands as per
|
|
POSIX (still have to sort out variable assignment errors).
|
|
* starting jobs that save/change/restore tty settings in the background
|
|
no longer messes up tty settings when job finishes.
|
|
* the pattern [a'-'z] now matches three characters, not 26, and
|
|
the pattern [ab']'] also matches three characters.
|
|
|
|
* a mostly complete man page! (work is still in progress)
|
|
|
|
* quoting inside $(..) mostly works.
|
|
|
|
* error reporting has been orthogonalized.
|
|
|
|
* brace expansion on by default (can be disabled with set +o braceexpand, or
|
|
set -o posix).
|
|
|
|
* output of "set -o" now fits on a normal screen.
|
|
|
|
* co-processes added (|&, read -p, print -p, etc.).
|
|
|
|
* restricted mode added (for what its worth).
|
|
|
|
* vi now prints meta characters with M- prefix, unless vi-show8 option is on.
|
|
|
|
Version 5.0.8
|
|
|
|
* bug fixes
|
|
* two problems in fc (introduced in 5.0.7)
|
|
* install target in Makefile missing a dollar
|
|
|
|
Version 5.0.7
|
|
|
|
* POSIX command command added
|
|
|
|
* a few bug fixes
|
|
* now compiles with various options undefined (eg, VI, EMACS, JOBS).
|
|
* fixed typos in Makefile.in (maxext -> manext) and ksh.1 (\f -> \fP).
|
|
* CLK_TCK defined to correct value for FreeBSD 1.1.5 (and earlier?).
|
|
* original process group restored when an exec is done.
|
|
* the exit value of set is that of the last $(...) on the command line.
|
|
* ditto for a command with no command (eg, x=`false`).
|
|
* command variable assignments done before path search (so PATH=... x works)
|
|
and are added as they are processed (so A=1 B=$A works).
|
|
* variable assignments infront of function calls are exported to programs
|
|
inside the function.
|
|
* aliases with trailing space are only honoured in command contexts
|
|
if in posix mode.
|
|
|
|
* make depend target added; install target warns if ksh not in /etc/shells.
|
|
|
|
* set -o bgnice now does something.
|
|
|
|
* vi mode: ESC is no longer a file completion command (too annoying).
|
|
|
|
Version 5.0.6
|
|
|
|
* most reported bugs/problems fixed (all but two).
|
|
|
|
* temporary files now created in $TMPDIR (if it is a sane path).
|
|
|
|
Version 5.0.5
|
|
|
|
* function parsing POSIXized (function bodies can be any compound command,
|
|
redirections after functions effect function invocation, not the
|
|
instantiation, the () in a function definition now parsed as two tokens).
|
|
|
|
* exit bultin now does stopped jobs check.
|
|
|
|
* set -p/-o priviliged supported.
|
|
|
|
* test builtin now believed to be completely posix.
|
|
|
|
* a default path is now used when PATH is not set (defined in options.h).
|
|
|
|
Version 5.0.4
|
|
|
|
* configuration checks for buggy opendir()s and setpgrp()s.
|
|
|
|
* autoloading functions now supported.
|
|
|
|
* functions can safely redefine themselves.
|
|
|
|
Version 5.0.3
|
|
|
|
* hash command changed to "alias -t"; whence -p added; print -s added
|
|
(all as in at&t ksh); unalias -a added (POSIX).
|
|
|
|
* test builtin POSIX complient
|
|
|
|
* TMOUT parameter supported (at&t ksh: timeout interactive shells)
|
|
|
|
Version 5.0.2
|
|
|
|
* trap/error handling changed to eliminate longjmp()s from signal handlers;
|
|
trap ERR added.
|
|
|
|
* ksh conditional expressions ([[ .. ]]) supported.
|
|
|
|
* arithmetic expressions (let, $((..)), etc.) now understand full C
|
|
integer expressions (except ++/-- and sizeof()).
|
|
|
|
* typeset -L -R -Z -u -l added (as in at&t ksh)
|
|
|
|
* at&t/posix $(( .. )) arithmetic expansions supported.
|
|
|
|
Version 5.0.1
|
|
|
|
* set -e no longer effects commands executed as part of if/while/until/&&/||/!
|
|
condition.
|
|
|
|
* posix ! keyword now recognized.
|
|
|
|
* posix getopts; if not in posix mode, getopts will accept options starting
|
|
with + (at&t kshism)
|
|
|
|
* syntax error messages improved (says what was unexpected/unmatched)
|
|
|
|
Version 4.9+mun.5
|
|
|
|
* all known bugs related to job control fixed:
|
|
* fg,bg,jobs,wait,kill commands fully POSIX complient
|
|
* signals are no longer reported for foreground jobs killed by SIGINT and
|
|
SIGPIPE
|
|
* pipeline process groups now created more reliablely (was a problem
|
|
if first process exited before second process exec'd).
|
|
* "(: ; cat /etc/termcap) | sleep" nolonger hangs
|
|
|
|
* save/restore tty mode if command succeeds/fails, respectively. Edit
|
|
mode (emacs,vi) no longer use old tty mode information
|
|
|
|
* test command: added -h
|
|
|
|
* alternations option renamed to braceexpand (eg, use set -o braceexpand).
|
|
Old usage (set -o alternations) still accepted (will disappear in next
|
|
version).
|
|
|
|
* trap/kill now accept upper and lower case signal names.
|
|
|
|
Version 4.9+mun.3
|
|
|
|
* here documents in functions now work properly
|
|
|
|
* read command: added -s option, use REPLY if no variable specified
|
|
|
|
* don't accept "while command; done" as a valid command
|
|
|
|
* fg,bg,jobs,wait,kill commands mostly POSIX complient.
|
|
|
|
* unset command: added POSIX -v option
|
|
|
|
* set command: added -A option
|
|
|
|
* handle ${array[@]} and ${array[*]}
|
|
|
|
* compiles with old bsd 4.2 compiler (pcc)
|
|
|
|
* new versions of etc/profile and etc/ksh.profile
|
|
|
|
Version 4.9+mun.2 (versus 4.9)

|
|
|
* directory/file structure has been re-arranged:
|
|
* moved files from sh directory up a level, deleted sh directory
|
|
* created misc directory, old ChangeLog,README,.. files moved to misc
|
|
|
|
* now uses GNU autoconf for compilation.
|
|
|
|
* no longer uses stdio FILE *'s for I/O redirection (most stdio
|
|
usage has been removed). Solves many porting problems caused by
|
|
dup'd file descriptors, forked processes and exiting.
|
|
|
|
* removed lint from code (compiles with very few warning with gcc -O -Wall
|
|
-Wno-comment)
|
|
|
|

|
|
* ulimit command now more functional on more machines. Compatible with at&t ksh.
|
