Bug fixes:
- ls --dereference no longer outputs erroneous "argetm" strings for
dangling symlinks when an 'ln=target' entry is in $LS_COLORS.
[bug introduced in fileutils-4.0]
- ls -lL symlink once again properly prints "+" when the referent has
an ACL. [bug introduced in coreutils-8.13]
- sort -g no longer infloops for certain inputs containing NaNs [bug
introduced in coreutils-8.5]
- chown and chgrp with the -v --from= options, now output the correct
owner. I.E. for skipped files, the original ownership is output,
not the new one. [bug introduced in sh-utils-2.0g]
- cp -r could mistakenly change the permissions of an existing
destination directory. [bug introduced in coreutils-6.8]
- cp -u -p would fail to preserve one hard link for each up-to-date
copy of a src-hard-linked name in the destination tree. I.e., if
s/a and s/b are hard-linked and dst/s/a is up to date, "cp -up s
dst" would copy s/b to dst/s/b rather than simply linking dst/s/b
to dst/s/a. [This bug appears to have been present in "the
beginning".]
- fts-using tools (rm, du, chmod, chgrp, chown, chcon) no longer use
memory proportional to the number of entries in each directory they
process. Before, rm -rf 4-million-entry-directory would consume
about 1GiB of memory. Now, it uses less than 30MB, no matter how
many entries there are. [this bug was inherent in the use of fts:
thus, for rm the bug was introduced in coreutils-8.0. The prior
implementation of rm did not use as much memory. du, chmod, chgrp
and chown started using fts in 6.0. chcon was added in
coreutils-6.9.91 with fts support. ]
- pr -T no longer ignores a specified LAST_PAGE to stop at. [bug
introduced in textutils-1.19q]
- printf '%d' '"' no longer accesses out-of-bounds memory in the
diagnostic. [bug introduced in sh-utils-1.16]
- split --number l/... no longer creates extraneous files in certain
cases. [bug introduced in coreutils-8.8]
- timeout now sends signals to commands that create their own process
group. timeout is no longer confused when starting off with a
child process. [bugs introduced in coreutils-7.0]
- unexpand -a now aligns correctly when there are spaces spanning a
tabstop, followed by a tab. In that case a space was dropped,
causing misalignment. We also now ensure that a space never
precedes a tab. [bug introduced in coreutils-5.3.0]
New features:
- date now accepts ISO 8601 date-time strings with "T" as the
separator. It has long parsed dates like "2004-02-29 16:21:42"
with a space between the date and time strings. Now it also parses
"2004-02-29T16:21:42" and fractional-second and time-zone-annotated
variants like "2004-02-29T16:21:42.333-07:00"
- md5sum accepts the new --strict option. With --check, it makes the
tool exit non-zero for any invalid input line, rather than just warning.
This also affects sha1sum, sha224sum, sha384sum and sha512sum.
- split accepts a new --filter=CMD option. With it, split filters
output through CMD. CMD may use the $FILE environment variable,
which is set to the nominal output file name for each invocation of
CMD. For example, to split a file into 3 approximately equal
parts, which are then compressed:
split -n3 --filter='xz > $FILE.xz' big
Note the use of single quotes, not double quotes. That creates
files named xaa.xz, xab.xz and xac.xz.
- timeout accepts a new --foreground option, to support commands not
started directly from a shell prompt, where the command is
interactive or needs to receive signals initiated from the
terminal.
Improvements:
- md5sum --check now supports the -r format from the corresponding
BSD tool. This also affects sha1sum, sha224sum, sha384sum and
sha512sum.
- pwd now works also on systems without openat. On such systems, pwd
would fail when run from a directory whose absolute name contained
more than PATH_MAX / 3 components. The df, stat and readlink
programs are also affected due to their use of the canonicalize_*
functions.
- join --check-order now prints "join: FILE:LINE_NUMBER: bad_line"
for an unsorted input, rather than e.g., "join: file 1 is not in
sorted order".
- shuf outputs small subsets of large permutations much more
efficiently. For example `shuf -i1-$((2**32-1)) -n2` no longer
exhausts memory.
- stat -f now recognizes the GPFS, MQUEUE and PSTOREFS file system
types.
- timeout now supports sub-second timeouts.
Changes in behavior:
- chmod, chown and chgrp now output the original attributes in
messages, when -v or -c specified.
- cp -au (where --preserve=links is implicit) may now replace newer
files in the destination, to mirror hard links from the source.
