* tests/chown/basic.sh: Add a case ensuring that "chown
--no-dereference" on a symlink to a directory operates on the link
itself and does not dereference it to change the owner of the target
directory.

We currently prefer the 'tty: link' style for representing URIs
in man pages, as this falls back to _not_ displaying the URI
where not supported, whereas the .UR macro generally does fall back
to showing the URI, which has these disadvantages:
- They're long, redundant, and interfere when reading text
- With wrapping enabled with \: in the URI, it can become unclickable
- Without wrapping enabled it interferes in adjacent text justification
Note with groff >= 1.24 (March 2026), the .UR macro results
in OSC 8 hyperlinks being used, and thus the awkward URI is not
displayed.
* man/viewman: Configure groff 1.23 to display .UR macros
with OSC 8 hyperlinks.
See: https://lists.gnu.org/r/coreutils/2026-05/msg00080.html
* tests/sort/sort-merge.pl: Add 'long-lines' case ensuring that
merging input whose lines exceed the read buffer does not split
lines on buffer boundaries.
https://github.com/coreutils/coreutils/pull/270
The default shell-escape quoting style escapes control characters in
file names (e.g. newlines) as $'...' sequences, but no test exercised
this; only the single-quote character was covered.

* tests/stat/stat-fmt.sh: Add a case with a file name containing
contiguous and separated newlines.

This patch only improves some error messages. Here is the behavior
before the patch:
$ printenv -i
Try 'printenv --help' for more information.
$ printenv -u
printenv: option requires an argument -- 'u'
Try 'printenv --help' for more information.
$ printenv -u a
Try 'printenv --help' for more information.
Here is the behavior after:
$ ./src/printenv -i
./src/printenv: invalid option -- 'i'
Try './src/printenv --help' for more information.
$ ./src/printenv -u
./src/printenv: invalid option -- 'u'
Try './src/printenv --help' for more information.
$ ./src/printenv -u a
./src/printenv: invalid option -- 'u'
Try './src/printenv --help' for more information.
* src/printenv.c (main): Remove 'i' and 'u' from the short options given
to getopt_long.
* src/tail.c (write_header): Use quotef() to quote
file names when needed.
* src/head.c (write_header): Likewise.
* tests/head/quote-headers.sh: Add a new test.
* tests/tail/quote-headers.sh: Add a new test.
* tests/local.mk: Reference the new test.

This fixes an issue in unreleased commit f77f365ef (shred: don't block
when opening FIFOs with no readers, 2026-05-09).
* src/shred.c: Save the errno before calling stat and use it in the
error message.
* tests/shred/fifo.sh: Call getlimits_ and uses_strace_. Add a test
case.
* tests/tee/short-write.sh: Check that all the required strace
options are supported, which is not the case with strace 5.10 at least.
* tests/tee/write-eagain.sh: Likewise.
* NEWS: Mention the bug fixes.
* THANKS.in: Add Bernhard M. Wiedemann for reporting the bugs.
* src/iopoll.c (close_wait): Remove function.
(write_wait): Don't call wait_for_nonblocking_write if write is
successful. Handle errors more robustly.
* src/iopoll.h (close_wait): Remove declaration.
* src/tee.c (tee_files): Use close instead of close_wait.
* tests/tee/short-write.sh: New test for the bug.
* tests/tee/write-eagain.sh: Likewise.
* tests/local.mk (all_tests): Add the new tests.
Fixes https://bugs.gnu.org/81060
This test failure was seen on NetBSD 10.0 machine, where ulimit failed
with EINVAL.
* tests/dd/bytes.sh: Don't fail the test case if ulimit fails.
Reported by Bruno Haible.
The only use of this header was removed in commit d52092958 (chroot:
call chroot() unconditionally to handle bind mounted "/", 2014-10-15).
* src/chroot.c: Don't include root-dev-ino.h.
The only use of this header was removed in commit 97d8dcc5c (basenc:
prefer signed to unsigned integers, 2021-08-27).
* src/basenc.c: Don't include xdectoint.h.
It has not been needed since commit 9fd2c631b (Remove all uses of
signals; modern hosts have /dev/random and don't need this gorp.,
2005-04-09).
* src/shred.c: Don't include setjmp.h.
* src/shred.c (usage): Mention the behavior of 'shred' on FIFOs,
sockets, and terminals.
* doc/coreutils.texi (shred invocation): Likewise.

This mostly either removes casts if they are always no-ops, or
replaces casts (TYPE)(EXPR) with compound literals (TYPE){EXPR}.
Compound literals are a bit safer anyway, as casts are too
powerful in C.
* src/cksum_avx2.c (cksum_avx2):
* src/cksum_avx512.c (cksum_avx512):
* src/cksum_crc.c (cksum_slice8):
* src/cksum_pclmul.c (cksum_pclmul):
* src/cp-hash.c (remember_copied):
* src/numfmt.c (simple_strtod_float):
* src/system.h (x_timestyle_match):
Omit no-op casts.
* src/cp-hash.c (src_to_dest_hash):
* src/dd.c (dd_copy):
* src/df.c (devlist_hash):
* src/env.c (splitbuf_append_byte):
* src/getlimits.c (print_int, main):
* src/ls.c (dev_ino_hash):
* src/truncate.c (do_ftruncate):
Replace casts with compound literals.
* src/factor.c: Ignore -Wuseless-cast, as we include the imported
longlong.h file, which has many of them.
* src/numfmt.c (powerld): 2nd arg is now ptrdiff_t, not int, so
that integers are not silently mishandled in outlandish cases.
* NEWS: Mention the bug fix.
* src/shred.c (wipefile): Open the file with O_NONBLOCK.
* tests/shred/fifo.sh: New file.
* tests/local.mk (all_tests): Add the new test.
This is useful in many man pages like date , dd, od, tr, ...
where there are tables presented, where extraneous lines
between each entry are best avoided.
* man/help2man: Use .PD 0 (Paragraph Distance)
to avoid extraneous blank lines within .TP delineated tables.
Also use explicit widths with .TP in such tables,
to preserve the alignment from the --help output.
On an AMD Ryzen 7 3700X running GNU/Linux:
$ timeout 30 taskset 1 ./src/shuf-prev \
-r -i 1000000-1000000 | pv -r > /dev/null
[ 302MiB/s]
$ timeout 30 taskset 1 ./src/shuf \
-r -i 1000000-1000000 | pv -r > /dev/null
[ 434MiB/s]
* src/shuf.c (print_number): New function.
(write_permuted_numbers, write_random_numbers): Use it.
* tests/shuf/shuf.sh: Add a test case to run 'shuf -i' with varying
numbers of digits to check that the string conversion is correct.
* tests/ls/acl.sh: Check that the gap between the '+' indicator and
the link count is the same whether the listing contains one or
several ACL entries.
https://github.com/coreutils/coreutils/pull/251
* src/ls.c (calculate_columns): Treat width as inclusive max.
(print_with_separator): Likewise. Also handle commas explicitly,
since they're not catered for by an implicit newline in the count.
* tests/ls/w-option.sh: Adjust exact-fit column tests.
Note this change also makes the existing `ls -w4 -x -T0 a b` test
behave consistently with other output width limits.
Also add the test case from:
https://github.com/coreutils/coreutils/pull/213
* tests/ls/m-option.sh: Add a test case to ensure appropriate
wrapping when trailing comma at the line limit.
* NEWS: Mention the change in behavior.
In the edge case where the right most column would
consist of only files taking 1 or 2 cells, we accounted
for 3 cells, which would result in using 1 column too few.
This should have been part of commit v8.24-59-ge71be1292
* src/ls.c (init_column_info): Don't account for separator
in the the final column.
* tests/ls/w-option.sh: Add a test case.
Note were links are not supported (like on Solaris or FreeBSD),
the text still displays normally.
* man/chmod.x: Link from "numeric mode" in chmod man page,
to more detailed online info.
Previously the string from strerror would only be printed for some
algorithms:
$ cksum -a sha2 -l 256 /dev/null > /dev/full
cksum: write error: No space left on device
$ cksum -a sysv /dev/null > /dev/full
cksum: write error
This patch fixes it so that the error information is always printed:
$ ./src/cksum -a sha2 -l 256 /dev/null > /dev/full
cksum: write error: No space left on device
$ ./src/cksum -a sysv /dev/null > /dev/full
cksum: write error: No space left on device
* src/cksum.c (output_file): Don't check for a write error here.
(main): Check for it here instead.
* tests/misc/io-errors.sh: Add a 'cksum' invocation for each supported
algorithm.
https://github.com/coreutils/coreutils/issues/258
This matches the manual, as well as the -u option,
and should help reduce confusion.
* src/test.c (usage): Fix -g documentation to match the structure of -u
* src/unexpand.c (unexpand): Use xinmalloc() to gracefully
handle overflow. Also use the runtime locale specific MB_CUR_MAX
rather than the worst case MB_LEN_MAX.
* tests/unexpand/mb.sh: Add a test case that fails in a default
glibc build with either MB_CUR_MAX or MB_LEN_MAX.
* NEWS: Mention the bug fix.
