Use "configure --help" for information + on what the options do (they are basicly the same as what was in the + options.h file). Shell can be configured as a (almost) plain bourne + shell using the --enable-shell=sh (also generates appropriate man page). + Installed name of program (ksh or sh) can be modified using configure's + --program-* options. + +* ulimit: added -p (maxproc) option. + +* case statements can use the old syntax of {,} instead of in,esac. + +* extended file globbing added (eg, f*(bar|Bar) matches f, fbar fBarbar, etc). + +* trim expressions can be of the form ${parameter#pattern1|pattern2|...}. + +* if compiled as sh, $ENV included only if posix option is set. + +* vi: U command added (undo all changes on line). + +* the Bugs script has been replaced by a new regression testing system, kept + in the tests/ directory (contains a perl script which sets up a test + environment and runs tests, and a bunch of tests). + + +Version 5.2.3 + +* bug fixes + * arrays: set -A and unset now unset whole array. + * history(complex version): fixed core caused by uninitialized hist_source. + * getopts: will continue parsing options if called after error. + * getopts: doesn't print shell name twice in error message. + * posix: if posix option is set, $0 is always the name of the shell. + * history: "fc -s foo" now finds foo if it is the most recent command. + * let: expression errors no longer cause scripts to exit. + * PS1: does not go into infinite loop if there is an expansion error. + * configure: memmove/bcopy test has a change of working now. + * configure: check for flock(), undefine COMPLEX_HISTORY if not found. + * substitution: tilde substitution works in word part of ${var[-+=?]word}. + * history: "fc <number>" now edits <number>, not <number> to most recent. + * cd: two argument form works again. + * special commands taking assignments (alias,set,etc.): field splitting, + file globbing, etc. suppressed only for args that look like assignments. + * command: -V now finds reserved words. + +* added support for Korn's /dev/fd tests + +* 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. + +Version 5.2.2 + +* bug fixes + * included c_test.h in distribution (opps). + +Version 5.2.1 + +* bug fixes + * emacs: buffer no longer overflowed when completing file names/commands. + * emacs: <ESC><tty-erase-char> now bound to delete-back-word (was ...-char). + * emacs: ignores a space char after ^V (version), as in at&t ksh. + * emacs: ^O bound to newline-and-next, ^X^Y bound to list-file. + * emacs: emacs words now include underscore. + * vi: set -o markdirs, directories and ^[= now get along. + * cd: -P no longer leaves .. and . in PWD. + * cd: if CDPATH set and can't cd, error doesn't contain any of CDPATH. + * cd: sets PWD properly, on machines without getwd(). + * configuration: unistd.h test fixed (include sys/types before dirent.h). + * configuration: detects memmove/bcopy's that don't handle overlaps. + * [[ ... ]] does lazy evaluation (eg, [[ ! -f foo || $(<foo) = bar ]] does + not evaluate $(<foo) if foo doesn't exist). + + +Version 5.2.0 + +* bug fixes + * vi: completion now allows globbing characters. + * vi: can deal with very long prompts. + * vi: .
