User visible changes in release 1.13
* `date -d "01/01/1998 3 years" +%Y' now works properly. It prints 2001.
* expr's match operator has been corrected to use basic regular expressions
* New programs: factor, seq.
* date accepts new option --rfc-822 (-R) and new %z format.
* date: fix bugs in the handling of date -u +'%s %Z'.
* date accepts new option --reference=FILE (-r FILE) analogous to the
like-named touch option.
* date can now format dates up to and including ones in the year 2037
User visible changes in release 1.12
* None.
User visible changes in release 1.11
* date accepts new option: (-f) --file=DATEFILE
* skeletal texinfo documentation (mainly just the `invoking' nodes)
* `stty werase ^W' works. Before, werase wasn't enabled for AIX-3.2.5.
* su with no arguments works properly
* nice accepts options like `--5' (this is interpreted like `-n -5')
* nice now interprets `-1 -1' like `-1' not like `-11'
* `stty speed' and `stty size' no longer output a spurious newline
User visible changes in release 1.10
* change package name from shellutils to sh-utils
* add hostname, pwd, and users commands
* --version outputs the name of the utility as well as the package name
and version number.
* Configure properly determines options for stty on SCO ODT 3.0 systems.
* `date -d' works better. Before, `date -d '4apr94'' produced
`Sun Apr 3 23:00:00 CDT 1994'.
User visible changes in release 1.9.4
* Repair stty option handling.
User visible changes in release 1.9.3
* `stty -a -g' gets a diagnostic
* `stty {-a|-g} any-other-argument' gets a diagnostic
* stty no longer ignores some of its arguments
* basename and dirname no longer treat `--' specially
* `basename -- file.c .c' generates a usage error. Before, it output `file'.
* `basename file-dist -dist' outputs `file'. Before it output `file-dist'.
* stty defaults `swtch' to undefined for Solaris so `susp' (^Z) will work.
Before, with the default settings ^Z did nothing.
* stty no longer gives an error message when it finds a spurious difference
(due to buggy tcgetattr/tcsetattr) between requested and current tty
modes under SunOS 4.1.x.
* stty no longer fails if the ioctl to determine the display width fails
when displaying settings.
* stty works around SunOS 4.x kernel bug that made `stty rows 0 cols 0' fail.
* who and tee no longer fail gratuitously when continued after an
interrupted read or write system call.
* date accepts new format: %s time in seconds since 1970-01-01 00:00:00 UCT
* date -d can parse dates like `11-JUL-1991'
* expr '' == 0 works (before, it printed 1)
* stty no longer fails on telnet sessions to Solaris systems
* `cd /etc; who utmp' now works. Before, any filename argument had to be
absolute or relative to /dev.
User visible changes in release 1.9.2:
* who output is better formatted on Solaris and other SysVr4 systems
* fix a minor problem in formatting the output from `stty -a'
* yes with arguments outputs newlines again
* partial stty failures are reported
Major changes in release 1.9.1:
* stty can be built on Suns again
* minor fix for who -q
Major changes in release 1.9:
* su fails gracefully when getpass is unable to open /dev/tty.
* printenv and tty detect and report write errors
* fix bug in stty
* stty accepts the new options status and flush on systems that provide them
* `expr 1 / 0' gives an error message rather than trying to divide by zero
* expr's `substr' doesn't overrun malloc'd buffer
* expr recognizes the string `0' as zero
* better support for Linux, Dec Alpha, and SGI Irix
* all programs (even true and false) accept --version and --help options
* uname's --version option is no longer equivalent to its -v option
* configure uses config.h, so DEFS won't exceed preprocessor limits of
some compilers on the number of symbols defined via -D.
* work around problem where $(srcdir)/config.h was used instead of
../config.h -- this happened only when building in a subdirectory
and when config.h remained in $(srcdir) from a previous ./configure.
* make may be run from the subdirectories
Major changes in release 1.8:
* add echo command
* fix some incorrect warnings in pathchk
* look at the right utmp file on 386BSD
* date doesn't dump core on some systems now
Major changes in release 1.7:
* add su, who, true, false commands
* add more tests to expr
* fix printf program handling of \ escapes
* printf can re-use format string for multiple groups of arguments
* printf catches numeric conversion errors with an ANSI C library
* stty nl and -nl were backwards
* date can format an arbitrary date without setting it
