[2.0.15] * date no longer accepts e.g., September 31 in the MMDDhhmm syntax * fix a bug in this package's .m4 files and in configure.ac [2.0.14] * nohup's behavior is changed as follows, to conform to POSIX 1003.1-2001: - nohup no longer adjusts scheduling priority; use "nice" for that. - nohup now redirects stderr to stdout, if stderr is not a terminal. - nohup exit status is now 126 if command was found but not invoked, 127 if nohup failed or if command was not found. [2.0.13] * uname and uptime work better on *BSD systems * pathchk now exits nonzero for a path with a directory component that specifies a non-directory [2.0.12] * kill: new program * who accepts new options: --all (-a), --boot (-b), --dead (-d), --login, --process (-p), --runlevel (-r), --short (-s), --time (-t), --users (-u). The -u option now produces POSIX-specified results and is the same as the long option `--users'. --idle is no longer the same as -u. * The following changes apply on systems conforming to POSIX 1003.1-2001, and are required by the new POSIX standard: - `date -I' is no longer supported. Instead, use `date --iso-8601'. - `nice -NUM' is no longer supported. Instead, use `nice -n NUM'. * New 'uname' options -i or --hardware-platform, and -o or --operating-system. 'uname -a' now outputs -i and -o information at the end. New uname option --kernel-version is an alias for -v. Uname option --release has been renamed to --kernel-release, and --sysname has been renamed to --kernel-name; the old options will work for a while, but are no longer documented. * 'expr' now uses the LC_COLLATE locale for string comparison, as per POSIX. * 'expr' now requires '+' rather than 'quote' to quote tokens; this removes an incompatibility with POSIX. * date -d 'last friday' would print a date/time that was one hour off (e.g., 23:00 on *thursday* rather than 00:00 of the preceding friday) when run such that the current time and the target date/time fall on opposite sides of a daylight savings time transition. This problem arose only with relative date strings like `last monday'. It was not a problem with strings that include absolute dates. * factor is twice as fast, for large numbers [2.0.11] * setting the date now works properly, even when using -u * `date -f - < /dev/null' no longer dumps core * some DOS/Windows portability changes [2.0j] * `date -d DATE' now parses certain relative DATEs correctly [2.0i] * fixed a bug introduced in 2.0h that made many programs fail with a `write error' when invoked with the --version option [2.0h] * all programs fail when printing --help or --version output to a full device * printf exits nonzero upon write failure * yes now detects and terminates upon write failure * date --rfc-822 now always emits day and month names from the `C' locale * portability tweaks for Solaris8, Ultrix, and DOS [2.0g] * date now handles two-digit years with leading zeros correctly. * printf interprets unicode, \uNNNN \UNNNNNNNN, on systems with the required support; from Bruno Haible. * stty's rprnt attribute now works on HPUX 10.20 * seq's --equal-width option works more portably [2.0f] * fix build problems with ut_name vs. ut_user [2.0e] * stty: fix long-standing bug that caused test failures on at least HPUX systems when COLUMNS was set to zero * still more portability fixes * unified lib/: now that directory and most of the configuration framework is common between fileutils, textutils, and sh-utils [2.0d] * fix portability problem with sleep vs lib/strtod.c's requirement for -lm [2.0c] * fix portability problems with nanosleep.c and with the new code in sleep.c [2.0b] * Regenerate lib/Makefile.in so that nanosleep.c is distributed. [2.0a] * sleep accepts floating point arguments on command line * sleep's clock continues counting down when sleep is suspended * when a suspended sleep process is resumed, it continues sleeping if there is any time remaining * who once again prints whatever host information it has, even without --lookup Changes in release 2.0 * disable stty tests (otherwise they fail) when `make check' is run via rsh [1.16m] * false and true now ignore --help and --version when POSIXLY_CORRECT is set [1.16l] * false and true are now C programs rather than shell scripts [1.16k] * fix typos in my version of AC_SEARCH_LIBS. * fix dates on config files so builders don't need autoconf/automake [1.16j] * work around problems with my use of AC_SEARCH_LIBS * fix a bug in id [1.16i] * portability tweaks for lib/readutmp.[ch] and src/date.c [1.16h] * seq with no arguments now elicits a useful diagnostic rather than a segfault * portability tweaks to work around utmpname differences * who works on Solaris [1.16g] * factor now uses uintmax_t, so the largest number it can factor is now 2^64 - 1 on systems with type `long long'. * nohup no longer modifies the shell's search path * `basename /' now prints `/', per the single unix spec * `who --lookup' no longer erroneously reports `localhost' for IP addresses for which it could not do a reverse lookup. * `id user' wouldn't report a group id in some situations. Now it always does. [1.16f] * chroot now calls chdir ("/") after chroot. * `date -s' now exits with nonzero status upon failure * new autoconf tests detect bugs in vendor mktime from Irix-6.4 and SunOS4.1.4 Your executables will be a little larger on such systems because you'll use GNU's mktime function, but date will work more reliably. * hostid: new program * `yes --help' and `yes --version' print those strings when the POSIXLY_CORRECT environment variable is set * who no longer does DNS lookups by default -- the new option, --lookup (-l), enables lookups [1.16e] * pinky: new lightweight finger-style program [1.16d] * the groups script now exits non-zero and doesn't print anything more when `id' fails [1.16c] * date -u -d DATE now prints the correct date * don't remove already-installed su unless it is possible to install the new one setuid root. [1.16b] [1.16a] * expr accepts new unary operator, quote. * expr now returns 0 for failed matches where pattern contained e.g., `\\(' * date -d DATE now works on Unicos systems * add tests for factor and more for date. * factor runs a lot faster for large 64-bit inputs * date works with relative offsets involving the `next' keyword Changes in release 1.16 * stty -tabs works properly * add tests for date * date --date "02/29/1996 - 1 year" now works properly Changes in release 1.15 * nice works with very recently-changed GNU libc getopt * fix several bugs in m4 macros used to create `configure' script * id works on systems with disfunctional getgroups function * uptime configure test detects /proc/uptime on Linux Changes in release 1.14 * fix bug in getdate.y that broke date's --date=DATE option on systems like SunOS4. * expr treats unadorned ? and + as literals. To make expr treat them as operators you have to use \? and \+. Changes in release 1.13 * two patches for ISC * Regenerate all Makefile.in using a patched version of automake-1.1l. [1.12s] * lots of little bug fixes -- see ChangeLog [1.12r] * uname --processor (-p) works on systems that have sysinfo and define SI_ARCHITECTURE. * stty works better on systems like i386-pc-isc3.0 * date --date=DATE accepts dates like those in an RCS log listing, e.g., `1992/11/01 05:44:34'. * printf now warns if excess arguments are ignored. * tee no longer fails immediately upon receipt of SIGPIPE [1.12q] * running `make check' runs tests of nice * lots of configuration-related improvements * nice allows `+' in options like -+8 and -+13. * when matching, expr warns about non-portability when the first character of the basic regular expression is `^' * `id user' no longer prints bogus group list * uses automake-generated Makefile templates * date accepts new %V format * date's %U and %W formats work properly * nice option handling works with 2-digit old-style-option adjustments. Now, `nice -18 -- nice' prints `18'. Before it printed `8'. * internationalized diagnostic messages * `date -d "01/01/1998 3 years" +%Y' now works properly. It prints 2001. * New programs: chroot, factor, seq, uptime. * date accepts new option: --rfc-822 (-R) * date accepts new format, %z, for RFC-822 style numeric timezone (-0500) * 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 ======================================================================== Copyright (C) 1992-2003, 2009-2010 Free Software Foundation, Inc.
