3 * date -d 'last friday' print a date/time that was one hour off
4 (e.g., 23:00 on *thursday* rather than 00:00 of the preceding friday)
5 when run such that the current time and the target date/time fall on
6 opposite sides of a daylight savings time transition.
7 This problem arises only with relative date strings like `last monday'.
8 It is not a problem with strings that include absolute dates.
10 * setting the date now works properly, even when using -u
11 * `date -f - < /dev/null' no longer dumps core
12 * some DOS/Windows portability changes
14 * `date -d DATE' now parses certain relative DATEs correctly
16 * fixed a bug introduced in 2.0h that made many programs fail with a
17 `write error' when invoked with the --version option
19 * all programs fail when printing --help or --version output to a full device
20 * printf exits nonzero upon write failure
21 * yes now detects and terminates upon write failure
22 * date --rfc-822 now always emits day and month names from the `C' locale
23 * portability tweaks for Solaris8, Ultrix, and DOS
25 * date now handles two-digit years with leading zeros correctly.
26 * printf interprets unicode, \uNNNN \UNNNNNNNN, on systems with the
27 required support; from Bruno Haible.

29 * seq's --equal-width option works more portably
31 * fix build problems with ut_name vs. ut_user
33 * stty: fix long-standing bug that caused test failures on at least HPUX
34 systems when COLUMNS was set to zero
35 * still more portability fixes
36 * unified lib/: now that directory and most of the configuration framework
37 is common between fileutils, textutils, and sh-utils
39 * fix portability problem with sleep vs lib/strtod.c's requirement for -lm
41 * fix portability problems with nanosleep.c and with the new code in sleep.c
43 * Regenerate lib/Makefile.in so that nanosleep.c is distributed.
45 * sleep accepts floating point arguments on command line
46 * sleep's clock continues counting down when sleep is suspended
47 * when a suspended sleep process is resumed, it continues sleeping if
48 there is any time remaining
49 * who once again prints whatever host information it has, even without --lookup
50 Changes in release 2.0
51 * disable stty tests (otherwise they fail) when `make check' is run via rsh
53 * false and true now ignore --help and --version when POSIXLY_CORRECT is set
55 * false and true are now C programs rather than shell scripts
57 * fix typos in my version of AC_SEARCH_LIBS.
58 * fix dates on config files so builders don't need autoconf/automake
60 * work around problems with my use of AC_SEARCH_LIBS
63 * portability tweaks for lib/readutmp.[ch] and src/date.c
65 * seq with no arguments now elicits a useful diagnostic rather than a segfault
66 * portability tweaks to work around utmpname differences
67 * who works on Solaris
69 * factor now uses uintmax_t, so the largest number it can factor is now 2^64 - 1
70 on systems with type `long long'.
71 * nohup no longer modifies the shell's search path
72 * `basename /' now prints `/', per the single unix spec
73 * `who --lookup' no longer erroneously reports `localhost' for IP addresses
74 for which it could not do a reverse lookup.
75 * `id user' wouldn't report a group id in some situations. Now it always does.
77 * chroot now calls chdir ("/") after chroot.
78 * `date -s' now exits with nonzero status upon failure
79 * new autoconf tests detect bugs in vendor mktime from Irix-6.4 and SunOS4.1.4
80 Your executables will be a little larger on such systems because you'll use
81 GNU's mktime function, but date will work more reliably.
83 * `yes --help' and `yes --version' print those strings when the POSIXLY_CORRECT
84 environment variable is set
85 * who no longer does DNS lookups by default -- the new option, --lookup (-l),
88 * pinky: new lightweight finger-style program
90 * the groups script now exits non-zero and doesn't print anything more
93 * date -u -d DATE now prints the correct date

99 * expr now returns 0 for failed matches where pattern contained e.g., `\\('

116 Changes in release 1.14
117 * fix bug in getdate.y that broke date's --date=DATE option on systems
119 * expr treats unadorned ? and + as literals. To make expr treat them as
120 operators you have to use \? and \+.
122 Changes in release 1.13
123 * two patches for ISC
124 * Regenerate all Makefile.in using a patched version of automake-1.1l.

142 * uses automake-generated Makefile templates
143 * date accepts new %V format
144 * date's %U and %W formats work properly
145 * nice option handling works with 2-digit old-style-option adjustments.
146 Now, `nice -18 -- nice' prints `18'. Before it printed `8'.
147 * internationalized diagnostic messages
148 * `date -d "01/01/1998 3 years" +%Y' now works properly. It prints 2001.
149 * New programs: chroot, factor, seq, uptime.
150 * date accepts new option: --rfc-822 (-R)
151 * date accepts new format, %z, for RFC-822 style numeric timezone (-0500)
152 * date: fix bugs in the handling of date -u +'%s %Z'.
153 * date accepts new option --reference=FILE (-r FILE) analogous to the

159 * date accepts new option: (-f) --file=DATEFILE
160 * skeletal texinfo documentation (mainly just the `invoking' nodes)

166 User visible changes in release 1.10
167 * change package name from shellutils to sh-utils
168 * add hostname, pwd, and users commands
169 * --version outputs the name of the utility as well as the package name
171 * Configure properly determines options for stty on SCO ODT 3.0 systems.
172 * `date -d' works better. Before, `date -d '4apr94'' produced
173 `Sun Apr 3 23:00:00 CDT 1994'.
174 User visible changes in release 1.9.4
175 * Repair stty option handling.
176 User visible changes in release 1.9.3
177 * `stty -a -g' gets a diagnostic
178 * `stty {-a|-g} any-other-argument' gets a diagnostic
179 * stty no longer ignores some of its arguments
180 * basename and dirname no longer treat `--' specially
181 * `basename -- file.c .c' generates a usage error. Before, it output `file'.
182 * `basename file-dist -dist' outputs `file'. Before it output `file-dist'.
183 * stty defaults `swtch' to undefined for Solaris so `susp' (^Z) will work.
184 Before, with the default settings ^Z did nothing.
185 * stty no longer gives an error message when it finds a spurious difference
186 (due to buggy tcgetattr/tcsetattr) between requested and current tty
187 modes under SunOS 4.1.x.
188 * stty no longer fails if the ioctl to determine the display width fails
189 when displaying settings.

195 * expr '' == 0 works (before, it printed 1)
196 * stty no longer fails on telnet sessions to Solaris systems
197 * `cd /etc; who utmp' now works. Before, any filename argument had to be

221 * configure uses config.h, so DEFS won't exceed preprocessor limits of
222 some compilers on the number of symbols defined via -D.
223 * work around problem where $(srcdir)/config.h was used instead of
224 ../config.h -- this happened only when building in a subdirectory
225 and when config.h remained in $(srcdir) from a previous ./configure.
226 * make may be run from the subdirectories
228 Major changes in release 1.8:
230 * fix some incorrect warnings in pathchk
