[ Here's an improved announcement, this time with a blurb about what
`coreutils' is, no MIME, and a list of the changes rather than a link. ]
I am happy to announce a stable release of the GNU coreutils.
The GNU coreutils package is the combination of and replacement
for the fileutils, sh-utils, and textutils packages.
This package contains the following programs:
[ basename cat chgrp chmod chown chroot cksum comm cp csplit cut date
dd df dir dircolors dirname du echo env expand expr factor false fmt
fold groups head hostid hostname id install join kill link ln logname
ls md5sum mkdir mkfifo mknod mv nice nl nohup od paste pathchk pinky pr
printenv printf ptx pwd readlink rm rmdir seq sha1sum shred sleep sort
split stat stty su sum sync tac tail tee test touch tr true tsort tty
uname unexpand uniq unlink uptime users vdir wc who whoami yes

the previous stable release. For the more details and attributions,
see the various ChangeLog files.
=================================================================
* Major changes in release 5.2.0 (2004-02-19) [stable]
** Bug fixes
none
* Major changes in release 5.1.3 (2004-02-08): candidate to become stable 5.2.0
** Bug fixes
`cp -d' now works as required even on systems like OSF V5.1 that
declare stat and lstat as `static inline' functions.
time stamps output by stat now include actual fractional seconds,
when available -- or .0000000 for files without that information.
seq no longer infloops when printing 2^31 or more numbers.
For reference, seq `echo 2^31|bc` > /dev/null takes about one hour
on a 1.6 GHz Athlon 2000 XP. Now it can output 2^53-1 numbers before
misbehaving.
* Major changes in release 5.1.2 (2004-01-25):
** Bug fixes
rmdir -p exits with status 1 on error; formerly it sometimes exited
with status 0 when given more than one argument.
nohup now always exits with status 127 when it finds an error,
as POSIX requires; formerly it sometimes exited with status 1.
Several programs (including cut, date, dd, env, hostname, nl, pr,
stty, and tr) now always exit with status 1 when they find an error;
formerly they sometimes exited with status 2.
factor no longer reports a usage error if stdin has the wrong format.
paste no longer infloops on ppc systems (bug introduced in 5.1.1)
* Major changes in release 5.1.1 (2004-01-17):
** Configuration option
You can select the default level of POSIX conformance at configure-time,
e.g., by ./configure DEFAULT_POSIX2_VERSION=199209
** Bug fixes
fold -s works once again on systems with differing sizes for int
and size_t (bug introduced in 5.1.0)
** New features
touch -r now specifies the origin for any relative times in the -d
operand, if both options are given. For example, "touch -r FOO -d
'-5 seconds' BAR" sets BAR's modification time to be five seconds
before FOO's.
join: The obsolete options "-j1 FIELD", "-j2 FIELD", and
"-o LIST1 LIST2..." are no longer supported on POSIX 1003.1-2001 systems.
Portable scripts should use "-1 FIELD", "-2 FIELD", and
"-o LIST1,LIST2..." respectively. If join was compiled on a
POSIX 1003.1-2001 system, you may enable the old behavior
by setting _POSIX2_VERSION=199209 in your environment.
* Major changes in release 5.1.0 (2003-12-21):
** New features
chgrp, chmod, and chown can now process (with -R) hierarchies of virtually
unlimited depth. Before, they would fail to operate on any file they
encountered with a relative name of length PATH_MAX (often 4096) or longer.
chgrp, chmod, chown, and rm accept the new options:
--preserve-root, --no-preserve-root (default)
chgrp and chown now accept POSIX-mandated -L, -H, and -P options
du can now process hierarchies of virtually unlimited depth.
Before, du was limited by the user's stack size and it would get a
stack overflow error (often a segmentation fault) when applied to
a hierarchy of depth around 30,000 or larger.
du works even when run from an inaccessible directory
du -D now dereferences all symlinks specified on the command line,
not just the ones that reference directories
du now accepts -P (--no-dereference), for compatibility with du
of NetBSD and for consistency with e.g., chown and chgrp
du's -H option will soon have the meaning required by POSIX
(--dereference-args, aka -D) rather then the current meaning of --si.
Now, using -H elicits a warning to that effect.
When given -l and similar options, ls now adjusts the output column
widths to fit the data, so that output lines are shorter and have
columns that line up better. This may adversely affect shell
scripts that expect fixed-width columns, but such shell scripts were
not portable anyway, even with old GNU ls where the columns became
ragged when a datum was too wide.
du accepts a new option, -0/--null, to make it produce NUL-terminated
output lines
** Bug fixes
printf, seq, tail, and sleep now parse floating-point operands
and options in the C locale. POSIX requires this for printf.
od -c -w9999999 no longer segfaults
csplit no longer reads from freed memory (dumping core on some systems)
csplit would mistakenly exhaust virtual memory in some cases
ls --width=N (for very large N) is no longer subject to an address
arithmetic bug that could result in bounds violations.
ls --width=N (with -x or -C) no longer allocates more space
(potentially much more) than necessary for a given directory.
dd `unblock' and `sync' may now be combined (e.g., dd conv=unblock,sync)
* Major changes in release 5.0.91 (2003-09-08):
** New features
date accepts a new option --rfc-2822, an alias for --rfc-822.
split accepts a new option -d or --numeric-suffixes.
cp, install, mv, and touch now preserve microsecond resolution on
file timestamps, on platforms that have the 'utimes' system call.
Unfortunately there is no system call yet to preserve file
timestamps to their full nanosecond resolution; microsecond
resolution is the best we can do right now.
sort now supports the zero byte (NUL) as a field separator; use -t '\0'.
The -t '' option, which formerly had no effect, is now an error.
sort option order no longer matters for the options -S, -d, -i, -o, and -t.
Stronger options override weaker, and incompatible options are diagnosed.
`sha1sum --check' now accepts the BSD format for SHA1 message digests
in addition to the BSD format for MD5 ones.
who -l now means `who --login', not `who --lookup', per POSIX.
who's -l option has been eliciting an unconditional warning about
this impending change since sh-utils-2.0.12 (April 2002).
** Bug fixes
Mistakenly renaming a file onto itself, e.g., via `mv B b' when `B' is
the same directory entry as `b' no longer destroys the directory entry
referenced by both `b' and `B'. Note that this would happen only on
file systems like VFAT where two different names may refer to the same
directory entry, usually due to lower->upper case mapping of file names.
Now, the above can happen only on file systems that perform name mapping and
that support hard links (stat.st_nlink > 1). This mitigates the problem
in two ways: few file systems appear to be affected (hpfs and ntfs are),
when the bug is triggered, mv no longer removes the last hard link to a file.
*** ATTENTION ***: if you know how to distinguish the following two cases
without writing to the file system in question, please let me know:
1) B and b refer to the same directory entry on a file system like NTFS
(B may well have a link count larger than 1)
2) B and b are hard links to the same file
stat no longer overruns a buffer for format strings ending in `%'
fold -s -wN would infloop for N < 8 with TABs in the input.
E.g., this would not terminate: printf 'a\t' | fold -w2 -s
`split -a0', although of questionable utility, is accepted once again.
`df DIR' used to hang under some conditions on OSF/1 5.1. Now it doesn't.
seq's --width (-w) option now works properly even when the endpoint
requiring the larger width is negative and smaller than the other endpoint.
seq's default step is 1, even if LAST < FIRST.
paste no longer mistakenly outputs 0xFF bytes for a nonempty input file
without a trailing newline.
`tail -n0 -f FILE' and `tail -c0 -f FILE' no longer perform what amounted
to a busy wait, rather than sleeping between iterations.
tail's long-undocumented --allow-missing option now elicits a warning
* Major changes in release 5.0.90 (2003-07-29):
** New features
sort is now up to 30% more CPU-efficient in some cases
`test' is now more compatible with Bash and POSIX:
`test -t', `test --help', and `test --version' now silently exit
with status 0. To test whether standard output is a terminal, use
`test -t 1'. To get help and version info for `test', use
`[ --help' and `[ --version'.
`test' now exits with status 2 (not 1) if there is an error.
wc count field widths now are heuristically adjusted depending on the input
size, if known. If only one count is printed, it is guaranteed to
be printed without leading spaces.
Previously, wc did not align the count fields if POSIXLY_CORRECT was set,
but POSIX did not actually require this undesirable behavior, so it
has been removed.
** Bug fixes
kill no longer tries to operate on argv[0] (introduced in 5.0.1)
Why wasn't this noticed? Although many tests use kill, none of
them made an effort to avoid using the shell's built-in kill.
`[' invoked with no arguments no longer evokes a segfault
rm without --recursive (aka -r or -R) no longer prompts regarding
unwritable directories, as required by POSIX.
uniq -c now uses a SPACE, not a TAB between the count and the
corresponding line, as required by POSIX.
expr now exits with status 2 if the expression is syntactically valid,
and with status 3 if an error occurred. POSIX requires this.
expr now reports trouble if string comparison fails due to a collation error.
split now generates suffixes properly on EBCDIC hosts.
split -a0 now works, as POSIX requires.
`sort --version' and `sort --help' fail, as they should
when their output is redirected to /dev/full.
`su --version > /dev/full' now fails, as it should.
** Fewer arbitrary limitations
cut requires 97% less memory when very large field numbers or
byte offsets are specified.
* Major changes in release 5.0.1 (2003-07-15):
** New programs
- - new program: `[' (much like `test')
** New features
- - head now accepts --lines=-N (--bytes=-N) to print all but the
N lines (bytes) at the end of the file
- - md5sum --check now accepts the output of the BSD md5sum program, e.g.,
MD5 (f) = d41d8cd98f00b204e9800998ecf8427e
- - date -d DATE can now parse a DATE string like May-23-2003
- - chown: `.' is no longer recognized as a separator in the OWNER:GROUP
specifier on POSIX 1003.1-2001 systems. If chown *was not* compiled
on such a system, then it still accepts `.', by default. If chown
was compiled on a POSIX 1003.1-2001 system, then you may enable the
old behavior by setting _POSIX2_VERSION=199209 in your environment.
- - chown no longer tries to preserve set-user-ID and set-group-ID bits;
on some systems, the chown syscall resets those bits, and previous
versions of the chown command would call chmod to restore the original,
pre-chown(2) settings, but that behavior is problematic.
1) There was a window whereby a malicious user, M, could subvert a
chown command run by some other user and operating on files in a
directory where M has write access.
2) Before (and even now, on systems with chown(2) that doesn't reset
those bits), an unwary admin. could use chown unwittingly to create e.g.,
a set-user-ID root copy of /bin/sh.
** Bug fixes
- - chown --dereference no longer leaks a file descriptor per symlink processed
- - `du /' once again prints the `/' on the last line
- - split's --verbose option works once again [broken in 4.5.10 and 5.0]
- - tail -f is no longer subject to a race condition that could make it
delay displaying the last part of a file that had stopped growing. That
bug could also make tail -f give an unwarranted `file truncated' warning.
- - du no longer runs out of file descriptors unnecessarily
- - df and `readlink --canonicalize' no longer corrupt the heap on
non-glibc, non-solaris systems
- - `env -u UNSET_VARIABLE' no longer dumps core on non-glibc systems
- - readlink's --canonicalize option now works on systems like Solaris that
lack the canonicalize_file_name function but do have resolvepath.
- - mv now removes `a' in this example on all systems: touch a; ln a b; mv a b
This behavior is contrary to POSIX (which requires that the mv command do
nothing and exit successfully), but I suspect POSIX will change.
- - date's %r format directive now honors locale settings
- - date's `-' (no-pad) format flag now affects the space-padded-by-default
conversion specifiers, %e, %k, %l
- - fmt now diagnoses invalid obsolescent width specifications like `-72x'
- - fmt now exits nonzero when unable to open an input file
- - tsort now fails when given an odd number of input tokens,
as required by POSIX. Before, it would act as if the final token
appeared one additional time.
** Fewer arbitrary limitations
- - tail's byte and line counts are no longer limited to OFF_T_MAX.
Now the limit is UINTMAX_MAX (usually 2^64).
- - split can now handle --bytes=N and --lines=N with N=2^31 or more.
** Portability
- - `kill -t' now prints signal descriptions (rather than `?') on systems
like Tru64 with __sys_siglist but no strsignal function.
- - stat.c now compiles on Ultrix systems
- - sleep now works on AIX systems that lack support for clock_gettime
- - rm now works around Darwin6.5's broken readdir function
Before `rm -rf DIR' would fail to remove all files in DIR
if there were more than 338.
