Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg –verify coreutils-9.6.tar.xz.sig
The signature should match the fingerprint of the following key:
pub rsa4096/0xDF6FD971306037D9 2011-09-23 [SC]
Key fingerprint = 6C37 DC12 121A 5006 BC1D B804 DF6F D971 3060 37D9
uid [ultimate] Pádraig Brady <P@draigBrady.com>
uid [ultimate] Pádraig Brady <pixelbeat@gnu.org>
If that command fails because you don’t have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the ‘gpg –verify’ command.
gpg –locate-external-key P@draigBrady.com
gpg –recv-keys DF6FD971306037D9
wget -q -O- ‘https://savannah.gnu.org/project/release-gpgkeys.php?group=coreutils&download=1’ | gpg –import –
As a last resort to find the key, you can try the official GNU
keyring:
wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
gpg –keyring gnu-keyring.gpg –verify coreutils-9.6.tar.xz.sig

NEWS
* Noteworthy changes in release 9.6 (2025-01-17) [stable]
** Bug fixes
cp fixes support for –update=none-fail, which would have been
rejected as an invalid option.
[bug introduced in coreutils-9.5]
cp,mv –update no longer overrides –interactive or –force.
[bug introduced in coreutils-9.3]
csplit no longer creates empty files given empty input.
[This bug was present in “the beginning”.]
ls and printf fix shell quoted output in the edge case of escaped
first and last characters, and single quotes in the string.
[bug introduced in coreutils-8.26]
ls -l no longer outputs “Permission denied” errors on NFS
which may happen with files without read permission, and which resulted
in inaccurate indication of ACLs (missing ‘+’ flag after mode).
[bug introduced in coreutils-9.4]
ls -l no longer outputs “Not supported” errors on virtiofs.
[bug introduced in coreutils-9.4]
mv works again with macFUSE file systems. Previously it would
have exited with a “Function not implemented” error.
[bug introduced in coreutils-8.28]
nproc gives more consistent results on systems with more than 1024 CPUs.
Previously it would have ignored the affinity mask on such systems.
[bug introduced with nproc in coreutils-8.1]
numfmt –from=iec-i now works with numbers without a suffix.
Previously such numbers were rejected with an error.
[bug introduced with numfmt in coreutils-8.21]
printf now diagnoses attempts to treat empty strings as numbers,
as per POSIX. For example, “printf ‘%d’ ”” now issues a diagnostic
and fails instead of silently succeeding.
[This bug was present in “the beginning”.]
pwd no longer outputs an erroneous double slash on systems
where the system getcwd() was completely replaced.
[bug introduced in coreutils-9.2]
‘shuf’ generates more-random output when the output is small.
[bug introduced in coreutils-8.6]
`tail –follow=name` no longer waits indefinitely for watched
file names that are moved elsewhere within the same file system.
[bug introduced in coreutils-8.24]
`tail –follow` without –retry, will consistently exit with failure status
where inotify is not used, when all followed files become inaccessible.
[This bug was present in “the beginning”.]
`tail –follow –pid=PID` will now exit when the PID dies,
even in the presence of blocking inputs like unopened fifos.
[This bug was present in “the beginning”.]
‘tail -c 4096 /dev/zero’ no longer loops forever.
[This bug was present in “the beginning”.]
** Changes in behavior
‘factor’ now buffers output more efficiently in some cases.
install -C now dereferences symlink sources when comparing,
rather than always treating as different and performing the copy.
kill -l and -t now list signal 0, as it’s a valid signal to send.
ls’s -f option now simply acts like -aU, instead of also ignoring
some earlier options. For example ‘ls -fl’ and ‘ls -lf’ are now
equivalent because -f no longer ignores an earlier -l. The new
behavior is more orthogonal and is compatible with FreeBSD.
stat -f -c%T now reports the “fuseblk” file system type as “fuse”,
given that there is no longer a distinct “ctl” fuse variant file system.
** New Features
cksum -a now supports the “crc32b” option, which calculates the CRC
of the input as defined by ITU V.42, as used by gzip for example.
For performance pclmul instructions are used where supported.
ls now supports the –sort=name option,
to explicitly select the default operation of sorting by file name.
printf now supports indexed arguments, using the POSIX:2024 specified
%<i>$ format, where ‘<i>’ is an integer referencing a particular argument,
thus allowing repetition or reordering of printf arguments.
test supports the POSIX:2024 specified ‘<‘ and ‘>’ operators with strings,
to compare the string locale collating order.
timeout now supports the POSIX:2024 specified -f, and -p short options,
corresponding to –foreground, and –preserve-status respectively.
** Improvements
cksum -a crc, makes use of AVX2, AVX512, and ARMv8 SIMD extensions
for time reductions of up to 40%, 60%, and 80% respectively.
‘head -c NUM’, ‘head -n NUM’, ‘nl -l NUM’, ‘nproc –ignore NUM’,
‘tail -c NUM’, ‘tail -n NUM’, and ‘tail –max-unchanged-stats NUM’
no longer fail merely because NUM stands for 2**64 or more.
sort operates more efficiently when used on pseudo files with
an apparent size of 0, like those in /proc.
stat and tail now know about the “bcachefs”, and “pidfs” file system types.
stat -f -c%T now reports the file system type,
and tail -f uses inotify for these file systems.
wc now reads a minimum of 256KiB at a time.
This was previously 16KiB and increasing to 256KiB was seen to increase
wc -l performance by about 10% when reading cached files on modern systems.
