* Noteworthy changes in release 9.1 (2022-04-15) [stable]
** Bug fixes
chmod -R no longer exits with error status when encountering symlinks.
All files would be processed correctly, but the exit status was incorrect.
[bug introduced in coreutils-9.0]
If 'cp -Z A B' checks B's status and some other process then removes B,
cp no longer creates B with a too-generous SELinux security context
before adjusting it to the correct value.
[bug introduced in coreutils-8.17]
'cp --preserve=ownership A B' no longer ignores the umask when creating B.
Also, 'cp --preserve-xattr A B' is less likely to temporarily chmod u+w B.
[bug introduced in coreutils-6.7]
On macOS, 'cp A B' no longer miscopies when A is in an APFS file system
and B is in some other file system.
[bug introduced in coreutils-9.0]
On macOS, fmt no longer corrupts multi-byte characters
by misdetecting their component bytes as spaces.
[This bug was present in "the beginning".]
'id xyz' now uses the name 'xyz' to determine groups, instead of xyz's uid.
[bug introduced in coreutils-8.22]
'ls -v' and 'sort -V' no longer mishandle corner cases like "a..a" vs "a.+"
or lines containing NULs. Their behavior now matches the documentation
for file names like ".m4" that consist entirely of an extension,
and the documentation has been clarified for unusual cases.
[bug introduced in coreutils-7.0]
On macOS, 'mv A B' no longer fails with "Operation not supported"
when A and B are in the same tmpfs file system.
[bug introduced in coreutils-9.0]
'mv -T --backup=numbered A B/' no longer miscalculates the backup number
for B when A is a directory, possibly inflooping.
[bug introduced in coreutils-6.3]
** Changes in behavior
cat now uses the copy_file_range syscall if available, when doing
simple copies between regular files. This may be more efficient, by avoiding
user space copies, and possibly employing copy offloading or reflinking.
chown and chroot now warn about usages like "chown root.root f",
which have the nonstandard and long-obsolete "." separator that
causes problems on platforms where user names contain ".".
Applications should use ":" instead of ".".
cksum no longer allows abbreviated algorithm names,
so that forward compatibility and robustness is improved.
date +'%-N' now suppresses excess trailing digits, instead of always
padding them with zeros to 9 digits. It uses clock_getres and
clock_gettime to infer the clock resolution.
dd conv=fsync now synchronizes output even after a write error,
and similarly for dd conv=fdatasync.
dd now counts bytes instead of blocks if a block count ends in "B".
For example, 'dd count=100KiB' now copies 100 KiB of data, not
102,400 blocks of data. The flags count_bytes, skip_bytes and
seek_bytes are therefore obsolescent and are no longer documented,
though they still work.
ls no longer colors files with capabilities by default, as file-based
capabilties are very rarely used, and lookup increases processing per file by
about 30%. It's best to use getcap [-r] to identify files with capabilities.
ls no longer tries to automount files, reverting to the behavior
before the statx() call was introduced in coreutils-8.32.
stat no longer tries to automount files by default, reverting to the
behavior before the statx() call was introduced in coreutils-8.32.
Only `stat --cached=never` will continue to automount files.
timeout --foreground --kill-after=... will now exit with status 137
if the kill signal was sent, which is consistent with the behavior
when the --foreground option is not specified. This allows users to
distinguish if the command was more forcefully terminated.
** New Features
dd now supports the aliases iseek=N for skip=N, and oseek=N for seek=N,
like FreeBSD and other operating systems.
dircolors takes a new --print-ls-colors option to display LS_COLORS
entries, on separate lines, colored according to the entry color code.
dircolors will now also match COLORTERM in addition to TERM environment
variables. The default config will apply colors with any COLORTERM set.
** Improvements
cp, mv, and install now use openat-like syscalls when copying to a directory.
This avoids some race conditions and should be more efficient.
On macOS, cp creates a copy-on-write clone if source and destination
are regular files on the same APFS file system, the destination does
not already exist, and cp is preserving mode and timestamps (e.g.,
'cp -p', 'cp -a').
The new 'date' option --resolution outputs the timestamp resolution.
With conv=fdatasync or conv=fsync, dd status=progress now reports
any extra final progress just before synchronizing output data,
since synchronizing can take a long time.
printf now supports printing the numeric value of multi-byte characters.
sort --debug now diagnoses issues with --field-separator characters
that conflict with characters possibly used in numbers.
'tail -f file | filter' now exits on Solaris when filter exits.
root invoked coreutils, that are built and run in single binary mode,
now adjust /proc/$pid/cmdline to be more specific to the utility
being run, rather than using the general "coreutils" binary name.
** Build-related
AIX builds no longer fail because some library functions are not found.
[bug introduced in coreutils-8.32]

Changelog:
* Noteworthy changes in release 9.0 (2021-09-24) [stable]
** Bug fixes
chmod -v no longer misreports modes of dangling symlinks.
[bug introduced in coreutils-5.3.0]
cp -a --attributes-only now never removes destination files,
even if the destination files are hardlinked, or the source
is a non regular file.
[bug introduced in coreutils-8.6]
csplit --suppress-matched now elides the last matched line
when a specific number of pattern matches are performed.
[bug introduced with the --suppress-matched feature in coreutils-8.22]
df no longer outputs duplicate remote mounts in the presence of bind mounts.
[bug introduced in coreutils-8.26]
df no longer mishandles command-line args that it pre-mounts
[bug introduced in coreutils-8.29]
du no longer crashes on XFS file systems when the directory hierarchy is
heavily changed during the run.
[bug introduced in coreutils-8.25]
env -S no longer crashes when given unusual whitespace characters
[bug introduced in coreutils-8.30]
expr no longer mishandles unmatched \(...\) in regular expressions.
[bug introduced in coreutils-6.0]
ls no longer crashes when printing the SELinux context for unstatable files.
[bug introduced in coreutils-6.9.91]
mkdir -m no longer mishandles modes more generous than the umask.
[bug introduced in coreutils-8.22]
nl now handles single character --section-delimiter arguments,
by assuming a second ':' character has been specified, as specified by POSIX.
[This bug was present in "the beginning".]
pr again adjusts tabs in input, to maintain alignment in multi column output.
[bug introduced in coreutils-6.9]
rm no longer skips an extra file when the removal of an empty directory fails.
[bug introduced by the rewrite to use fts in coreutils-8.0]
split --number=K/N will again correctly split chunk K of N to stdout.
Previously a chunk starting after 128KiB, output the wrong part of the file.
[bug introduced in coreutils-8.26]
tail -f no longer overruns a stack buffer when given too many files
to follow and ulimit -n exceeds 1024.
[bug introduced in coreutils-7.5]
tr no longer crashes when using --complement with certain
invalid combinations of case character classes.
[bug introduced in coreutils-8.6]
basenc --base64 --decode no longer silently discards decoded characters
on (1024*5) buffer boundaries
[bug introduced in coreutils-8.31]
** Changes in behavior
cp and install now default to copy-on-write (COW) if available.
cp, install and mv now use the copy_file_range syscall if available.
Also, they use lseek+SEEK_HOLE rather than ioctl+FS_IOC_FIEMAP on sparse
files, as lseek is simpler and more portable.
On GNU/Linux systems, ls no longer issues an error message on a
directory merely because it was removed. This reverts a change
that was made in release 8.32.
ptx -T no longer attempts to substitute old-fashioned TeX escapes
for 8-bit non-ASCII alphabetic characters. TeX indexes should
instead use '\usepackage[latin1]{inputenc}' or equivalent.
stat will use decomposed (major,minor) device numbers in its default format.
This is less ambiguous, and more consistent with ls.
sum [-r] will output a file name, even if only a single name is passed.
This is consistent with sum -s, cksum, and other sum(1) implementations.
** New Features
cksum now supports the -a (--algorithm) option to select any
of the existing sum, md5sum, b2sum, sha*sum implementations etc.
cksum now subsumes all of these programs, and coreutils
will introduce no future standalone checksum utility.
cksum -a now supports the 'sm3' argument, to use the SM3 digest algorithm.
cksum --check now supports auto detecting the digest type to use,
when verifying tagged format checksums.
expr and factor now support bignums on all platforms.
ls --classify now supports the "always", "auto", or "never" flags,
to support only outputting classifier characters if connected to a tty.
ls now accepts the --sort=width option, to sort by file name width.
This is useful to more compactly organize the default vertical column output.
ls now accepts the --zero option, to terminate each output line with
NUL instead of newline.
nl --line-increment can now take a negative number to decrement the count.
stat supports more formats for representing decomposed device numbers.
%Hd,%Ld and %Hr,%Lr will output major,minor device numbers and device types
respectively. %d corresponds to st_dev and %r to std_rdev.
** Improvements
cat --show-ends will now show \r\n as ^M$. Previously the \r was taken
literally, thus overwriting the first character in the line with '$'.
cksum [-a crc] is now up to 4 times faster by using a slice by 8 algorithm,
and at least 8 times faster where pclmul instructions are supported.
A new --debug option will indicate if pclmul is being used.
md5sum --check now supports checksum files with CRLF line endings.
This also applies to cksum, sha*sum, and b2sum.
df now recognizes these file systems as remote:
acfs, coda, fhgfs, gpfs, ibrix, ocfs2, and vxfs.
rmdir now clarifies the error if a symlink_to_dir/ has not been traversed.
This is the case on GNU/Linux systems, where the trailing slash is ignored.
stat and tail now know about the "devmem", "exfat", "secretmem", "vboxsf",
and "zonefs" file system types. stat -f -c%T now reports the file system
type, and tail -f uses polling for "vboxsf" and inotify for the others.
timeout now supports sub-second timeouts on macOS.
wc is up to 5 times faster when counting only new line characters,
where avx2 instructions are supported.
A new --debug option will indicate if avx2 is being used.

* Noteworthy changes in release 8.32 (2020-03-05) [stable]
** Bug fixes
cp now copies /dev/fd/N correctly on platforms like Solaris where
it is a character-special file whose minor device number is N.
[bug introduced in fileutils-4.1.6]
dd conv=fdatasync no longer reports a "Bad file descriptor" error
when fdatasync is interrupted, and dd now retries interrupted calls
to close, fdatasync, fstat and fsync instead of incorrectly
reporting an "Interrupted system call" error.
[bugs introduced in coreutils-6.0]
df now correctly parses the /proc/self/mountinfo file for unusual entries
like ones with '\r' in a field value ("mount -t tmpfs tmpfs /foo$'\r'bar"),
when the source field is empty ('mount -t tmpfs "" /mnt'), and when the
filesystem type contains characters like a blank which need escaping.
[bugs introduced in coreutils-8.24 with the introduction of reading
the /proc/self/mountinfo file]
factor again outputs immediately when stdout is a tty but stdin is not.
[bug introduced in coreutils-8.24]
ln works again on old systems without O_DIRECTORY support (like Solaris 10),
and on systems where symlink ("x", ".") fails with errno == EINVAL
(like Solaris 10 and Solaris 11).
[bug introduced in coreutils-8.31]
rmdir --ignore-fail-on-non-empty now works correctly for directories
that fail to be removed due to permission issues. Previously the exit status
was reversed, failing for non empty and succeeding for empty directories.
[bug introduced in coreutils-6.11]
'shuf -r -n 0 file' no longer mistakenly reads from standard input.
[bug introduced with the --repeat feature in coreutils-8.22]
split no longer reports a "output file suffixes exhausted" error
when the specified number of files is evenly divisible by 10, 16, 26,
for --numeric, --hex, or default alphabetic suffixes respectively.
[bug introduced in coreutils-8.24]
seq no longer prints an extra line under certain circumstances (such as
'seq -f "%g " 1000000 1000000').
[bug introduced in coreutils-6.10]
** Changes in behavior
Several programs now check that numbers end properly. For example,
'du -d 1x' now reports an error instead of silently ignoring the 'x'.
Affected programs and options include du -d, expr's numeric operands
on non-GMP builds, install -g and -o, ls's TABSIZE environment
variable, mknod b and c, ptx -g and -w, shuf -n, and sort --batch-size
and --parallel.
date now parses military time zones in accordance with common usage:
"A" to "M" are equivalent to UTC+1 to UTC+12
"N" to "Y" are equivalent to UTC-1 to UTC-12
"Z" is "zulu" time (UTC).
For example, 'date -d "09:00B" is now equivalent to 9am in UTC+2 time zone.
Previously, military time zones were parsed according to the obsolete
rfc822, with their value negated (e.g., "B" was equivalent to UTC-2).
[The old behavior was introduced in sh-utils 2.0.15 ca. 1999, predating
coreutils package.]
ls issues an error message on a removed directory, on GNU/Linux systems.
Previously no error and no entries were output, and so indistinguishable
from an empty directory, with default ls options.
uniq no longer uses strcoll() to determine string equivalence,
and so will operate more efficiently and consistently.
** New Features
ls now supports the --time=birth option to display and sort by
file creation time, where available.
od --skip-bytes now can use lseek even if the input is not a regular
file, greatly improving performance in some cases.
stat(1) supports a new --cached= option, used on systems with statx(2)
to control cache coherency of file system attributes,
useful on network file systems.
** Improvements
stat and ls now use the statx() system call where available, which can
operate more efficiently by only retrieving requested attributes.
stat and tail now know about the "binderfs", "dma-buf-fs", "erofs",
"ppc-cmm-fs", and "z3fold" file systems.
stat -f -c%T now reports the file system type, and tail -f uses inotify.

----------------------------------------------------------------
* Noteworthy changes in release 8.31 (2019-03-10) [stable]
** Bug fixes
'base64 a b' now correctly diagnoses 'b' as the extra operand, not 'a'.
[bug introduced in coreutils-5.3.0]
When B already exists, 'cp -il A B' no longer immediately fails
after asking the user whether to proceed.
[This bug was present in "the beginning".]
df no longer corrupts displayed multibyte characters on macOS.
[bug introduced with coreutils-8.18]
seq no longer outputs inconsistent decimal point characters
for the last number, when locales are misconfigured.
[bug introduced in coreutils-7.0]
shred, sort, and split no longer falsely report ftruncate errors
when outputting to less-common file types. For example, the shell
command 'sort /dev/null -o /dev/stdout | cat' no longer fails with
an "error truncating" diagnostic.
[bug was introduced with coreutils-8.18 for sort and split, and
(for shared memory objects only) with fileutils-4.1 for shred]
sync no longer fails for write-only file arguments.
[bug introduced with argument support to sync in coreutils-8.24]
'tail -f file | filter' no longer exits immediately on AIX.
[bug introduced in coreutils-8.28]
'tail -f file | filter' no longer goes into an infinite loop
if filter exits and SIGPIPE is ignored.
[bug introduced in coreutils-8.28]
** Changes in behavior
cksum, dd, hostid, hostname, link, logname, sleep, tsort, unlink,
uptime, users, whoami, yes: now always process --help and --version options,
regardless of any other arguments present before any optional '--'
end-of-options marker.
nohup now processes --help and --version as first options even if other
parameters follow.
'yes a -- b' now outputs 'a b' instead of including the end-of-options
marker as before: 'a -- b'.
echo now always processes backslash escapes when the POSIXLY_CORRECT
environment variable is set.
When possible 'ln A B' now merely links A to B and reports an error
if this fails, instead of statting A and B before linking. This
uses fewer system calls and avoids some races. The old statting
approach is still used in situations where hard links to directories
are allowed (e.g., NetBSD when superuser).
ls --group-directories-first will also group symlinks to directories.
'test -a FILE' is not supported anymore. Long ago, there were concerns about
the high probability of humans confusing the -a primary with the -a binary
operator, so POSIX changed this to 'test -e FILE'. Scripts using it were
already broken and non-portable; the -a unary operator was never documented.
wc now treats non breaking space characters as word delimiters
unless the POSIXLY_CORRECT environment variable is set.
** New features
id now supports specifying multiple users.
'date' now supports the '+' conversion specification flag,
introduced in POSIX.1-2017.
printf, seq, sleep, tail, and timeout now accept floating point
numbers in either the current or the C locale. For example, if the
current locale's decimal point is ',', 'sleep 0,1' and 'sleep 0.1'
now mean the same thing. Previously, these commands accepted only
C-locale syntax with '.' as the decimal point. The new behavior is
more compatible with other implementations in non-C locales.
test now supports the '-N FILE' unary operator (like e.g. bash) to check
whether FILE exists and has been modified since it was last read.
env now supports '--default-signal[=SIG]', '--ignore-signal[=SIG]', and
'--block-signal[=SIG], to setup signal handling before executing a program.
env now supports '--list-signal-handling' to indicate non-default
signal handling before executing a program.
** New commands
basenc is added to complement existing base64,base32 commands,
and encodes and decodes printable text using various common encodings:
base64,base64url,base32,base32hex,base16,base2,z85.
** Improvements
ls -l now better aligns abbreviated months containing digits,
which is common in Asian locales.
stat and tail now know about the "sdcardfs" file system on Android.
stat -f -c%T now reports the file system type, and tail -f uses inotify.
stat now prints file creation time when supported by the file system,
on GNU Linux systems with glibc >= 2.28 and kernel >= 4.11.
----------------------------------------------------------------
* Noteworthy changes in release 8.30 (2018-07-01) [stable]
** Bug fixes
'cp --symlink SRC DST' will again correctly validate DST.
If DST is a regular file and SRC is a symlink to DST,
then cp will no longer allow that operation to clobber DST.
Also with -d, if DST is a symlink, then it can always be replaced,
even if it points to SRC on a separate device.
[bugs introduced with coreutils-8.27]
'cp -n -u' and 'mv -n -u' now consistently ignore the -u option.
Previously, this option combination suffered from race conditions
that caused -u to sometimes override -n.
[bug introduced with coreutils-7.1]
'cp -a --no-preserve=mode' now sets appropriate default permissions
for non regular files like fifos and character device nodes etc.,
and leaves mode bits of existing files unchanged.
Previously it would have set executable bits on created special files,
and set mode bits for existing files as if they had been created.
[bug introduced with coreutils-8.20]
'cp --remove-destination file symlink' now removes the symlink
even if it can't be traversed.
[bug introduced with --remove-destination in fileutils-4.1.1]
ls no longer truncates the abbreviated month names that have a
display width between 6 and 12 inclusive. Previously this would have
output ambiguous months for Arabic or Catalan locales.
'ls -aA' is now equivalent to 'ls -A', since -A now overrides -a.
[bug introduced in coreutils-5.3.0]
'mv -n A B' no longer suffers from a race condition that can
overwrite a simultaneously-created B. This bug fix requires
platform support for the renameat2 or renameatx_np syscalls, found
in recent Linux and macOS kernels. As a side effect, ‘mv -n A A’
now silently does nothing if A exists.
[bug introduced with coreutils-7.1]
** Changes in behavior
'cp --force file symlink' now removes the symlink even if
it is self referential.
ls --color now matches file extensions case insensitively.
** New features
cp --reflink now supports --reflink=never to enforce a standard copy.
env supports a new -v/--debug option to show verbose information about
each processing step.
env supports a new -S/--split-string=S option to split a single argument
string into multiple arguments. Used to pass multiple arguments in scripts
(shebang lines).
md5sum accepts a new option: --zero (-z) to delimit the output lines with a
NUL instead of a newline character. This also disables file name escaping.
This also applies to sha*sum and b2sum.
rm --preserve-root now supports the --preserve-root=all option to
reject any command line argument that is mounted to a separate file system.
** Improvements
cut supports line lengths up to the max file size on 32 bit systems.
Previously only offsets up to SIZE_MAX-1 were supported.
stat and tail now know about the "exfs" file system, which is a
version of XFS. stat -f --format=%T now reports the file system type,
and tail -f uses inotify.
wc avoids redundant processing of ASCII text in multibyte locales,
which is especially significant on macOS.

dd: fix nocache regions passed to posix_fadvise()
Previously with oflag=direct the call to invalidate_cache()
was not passed to the kernel, as it was less than a page size,
and a subsequent call was not made to invalidate the pending space.
Similarly with oflag=nocache the pending space at EOF was
not invalidated. Even though these amount to only a single page
in the page cache it can be significant. For example on
XFS before kernel patch v4.9-rc1-4-g0ee7a3f, O_DIRECT files
would have been read inefficiently if any pages were cached,
even if they were already synced to storage.
* src/dd.c (i_nocache_eof, o_nocache_eof): New bools used
to control when we want invalidate_cache(,0) to clear to EOF.
(cache_round): Use IO_BUFSIZE (currently 132KiB) to minimize
calls to the relatively expensive advise function, rather
than page_size. This also makes it clear that while the
kernel function operates on pages, this size is chosen for
performance reasons.
(invalidate_cache): Refactor to share more code between
input and output paths. Use i_nocache_eof and o_nocache_eof
rather than proxying off max_records. Ensure we
invalidate full pages when clearing to EOF as the kernel
will ignore any non complete pages. Fix the offset used
for the output path.
(dd_copy): Invalidate the cache of the input after the
offset is updated, for consistency and so we don't try to
invalidate before the start of the file. When we read
EOF on input, set flags so that we invalidate to EOF.
(main): Invalidate to EOF in more cases, by depending
on the i_nocache_eof and o_nocache_eof flags.
* doc/coreutils.texi (dd invocation): Clarify the alignment
and persisted caveats on the example applying "nocache"
to part of a file.

runcon: revert "disable use of the TIOCSTI ioctl"

the setsid() fallback was not implemented correctly

the advice is to use `runcon ... setsid ...`

df: avoid stat() for dummy file systems with -l
When systemd is configured to automount a remote file system - see
'man systemd.automount(5)', then the mount point is initially
mounted by systemd with the file system type "autofs".
When the resource is used later on, then the wanted file system is
mounted over that mount point on demand.
'df -l' triggered systemd to mount the file system because it called
stat() on the mount point.
Instead of single-casing "autofs" targets, we can avoid stat()ing
all dummy file systems (which includes "autofs"), because those are
skipped later on in get_dev() anyway.
*src/df.c (filter_mount_list): Also skip dummy file systems unless
the -a option or a specific target are given.
* NEWS: Mention the fix.

ptx: fix some integer overflow bugs
Problem reported by Lukas Zachar at:
http://bugzilla.redhat.com/1482445
* src/ptx.c (line_width, gap_size, maximum_word_length)
(reference_max_width, half_line_width, before_max_width)
(keyafter_max_width, truncation_string_length, compare_words)
(compare_occurs, search_table, find_occurs_in_text, print_spaces)
(fix_output_parameters, define_all_fields):
Use ptrdiff_t, not int, for object offsets and sizes.
(WORD, OCCURS): Use ptrdiff_t, not short int.
(WORD_TABLE, number_of_occurs, generate_all_output):
Prefer ptrdiff_t to size_t where either will do.
(total_line_count, file_line_count, OCCURS, fix_output_parameters)
(define_all_fields):
Use intmax_t, not int, for line counts.
(DELTA): Remove. All uses changed.
(OCCURS, find_occurs_in_text, fix_output_parameters):
Use int, not size_t, for file indexes.
(tail_truncation, before_truncation, keyafter_truncation)
(head_truncation, search_table, define_all_fields)
(generate_all_output):
Use bool for booleans.
(digest_word_file, find_occurs_in_text):
Use x2nrealloc instead of checking for overflow by hand.
(find_occurs_in_text, fix_output_parameters, define_all_fields):
Omit unnecessary cast.
(fix_output_parameters): Don�<80><99>t assume integers fit in 11 digits.
(fix_output_parameters, define_all_fields):
Use sprintf return value rather than calling strlen.
(define_all_fields): Do not rely on sprintf to generate a string
that may contain more than INT_MAX bytes.
(main): Use xstrtoimax, not xstrtoul.
Use xnmalloc to catch integer overflow.
nohup: simplify by using fcntl
* src/nohup.c: Do not include cloexec.h.
(main): Use fcntl rather than dup + set_cloexec_flag.
sort: use pthread_sigmask, not sigprocmask
POSIX says sigprocmask has unspecified behavior in a multithreaded
program like �<80><98>sort�<80><99>.
* src/sort.c (pthread_sigmask) [GNULIB_defined_pthread_functions]:
New macro, for use when �<80><98>sort�<80><99> is not multithreaded.
(cs_enter, cs_leave): Use it. Pass address, not value, as
this is typically a tad faster. All callers changed.
sort: minor cleanups
* src/sort.c (move_fd): Rename from move_fd_or_die,
since it no longer can die.
sort: file descriptor discipline
Use O_CLOEXEC when creating file descriptors, so that subsidiary
processes do not inherit file descriptors that they do not need.
This is helpful for �<80><98>sort�<80><99>, as it is a multithreaded program that
forks and execs.
* bootstrap.conf (gnulib_modules): Add mkostemp, open, pipe2.
* src/sort.c (create_temp_file): Open temporary file with O_CLOEXEC.
(stream_open): Open the stream with O_CLOEXEC.
(pipe_fork): Create the pipe with O_CLOEXEC.
(check_output): Open the output file with O_CLOEXEC.

O_CLOEXEC is used properly. This is simpler anyway.

wording.

tests: avoid false failures on AIX
* tests/ln/sf-1.sh: Limit the symlink size to 1MiB

would equal 4294967295, as that's reserved on AIX.
Reported by Michael Felt.
sort: handle musl locale differences in --debug reporting
* src/sort.c (main): Don't assume hard_LC_COLLATE implies
a successful setting of the locale as musl defaults to
UTF8 when failing to set the specified locale.
* tests/misc/sort-debug-warn.sh: Adjust for the now

message back to the common case.

seq: produce consistent error messages upon write error
* src/seq.c (io_error): Use the same error message as would

maint: avoid spurious "make distcheck" failure
When the generated file, doc/constants.texi, happens to be older than
doc/coreutils.info, it will not be updated until/unless its generated
contents change. This is due to way that rule is careful to update
the file, to avoid provoking a pointless rerunning of makeinfo.
Note that this does not happen when one first runs "make distclean",
as recommended in README-release. However, I sometimes run it as
a more-rigorous "make check", and shouldn't have to manually run
"make distclean" first, in that case.
Before this change, one could reproduce the failure by running
`touch -dyesterday doc/constants.texi && make distcheck`. It would
fail with "makeinfo: could not open ../../doc/coreutils.info-t
for writing: Permission denied"

shred: fix invalid pattern generation for certain sizes
* src/shred.c (fillpattern): Fix the "off by one" issue when
testing whether we have enough space to copy the already
written portion of the buffer to the remainder of the buffer.
Specifically for buffer sizes that are (3*(2^x))+1, i.e. 7,13,...
we both use an uninitialized byte and invoke undefined
behavior in memcpy() operation on overlapping memory regions.
* tests/misc/shred-passes.sh: Add an invocation that will
trigger either valgrind UMR, or ASAN like:
ERROR: AddressSanitizer: memcpy-param-overlap: memory ranges
#1 0x403065 in fillpattern src/shred.c:293
A direct test is awkward due to the random writes surrounding
the problematic pattern writes.

2017-03-26 Pádraig Brady <P@draigBrady.com>
split: ensure input is processed when filters exit early
commit v8.25-4-g62e7af0 introduced the issue as it
broke out of the processing loop irrespective of
the value of new_file_flag which was used to indicate
a finite number of filters or not.
For example, this ran forever (as it should):
$ yes | split --filter="head -c1 >/dev/null" -b 1000
However this exited immediately due to EPIPE being propagated
back through cwrite and the loop not considering new filters:
$ yes | split --filter="head -c1 >/dev/null" -b 100000
Similarly processing would exit early for a bounded number of
output files, resulting in empty data sent to all but the first:
$ truncate -s10T big.in
$ split --filter='head -c1 >$FILE' -n 2 big.in
$ echo $(stat -c%s x??)
1 0
I was alerted to this code by clang-analyzer,
which indicated dead assigments, which is often
an indication of code that hasn't considered all cases.
* src/split.c (bytes_split): Change the last condition in
the processing loop to also consider the number of files
before breaking out of the processing loop.

timeout: fix race possibly terminating wrong process
The race is unlikely, as timeout(1) needs to receive a signal
in the few operations between waitpid() returning and exit().
Also the system needs to have reallocated the just released pid
in this time window.
Previously we never disabled the signal handler that sent
the termination signal to the "child" pid. However once waitpid()
has reaped the child, the system is free to allocate that pid,
so we must ensure we don't process any further signals.

Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F

* Noteworthy changes in release 8.26 (2016-11-30) [stable]
** Bug fixes
cp, mv, and install no longer run into undefined behavior when
handling ACLs on Cygwin and Solaris platforms. [bug introduced in
coreutils-8.24]
cp --parents --no-preserve=mode, no longer copies permissions from source
directories, instead using default permissions for created directories.
[bug introduced in coreutils-5.93]
chcon, chgrp, chmod, chown, du, and rm, or specifically utilities
using the FTS interface, now diagnose failures returned by readdir().
[this bug was inherent in the use of fts: thus, for rm the bug was
introduced in coreutils-8.0. du, chmod, chgrp and chown started using
fts in 6.0. chcon was added in coreutils-6.9.91 with fts support. ]
date, du, ls, and pr no longer mishandle time zone abbreviations on
System V style platforms where this information is available only
in the global variable 'tzname'. [bug introduced in coreutils-8.24]
factor again outputs immediately when numbers are input interactively.
[bug introduced in coreutils-8.24]
head no longer tries to process non-seekable input as seekable,
which resulted in failures on FreeBSD 11 at least.
[bug introduced in coreutils-8.24]
install -DZ and mkdir -pZ now set default SELinux context correctly even if
two or more directories nested in each other are created and each of them
defaults to a different SELinux context.
ls --time-style no longer mishandles '%%b' in formats.
[bug introduced in coreutils-7.2]
md5sum --check --ignore-missing no longer treats files with checksums
starting with "00" as missing. This also affects sha*sum.
[bug introduced with the --ignore-missing feature in coreutils-8.25]
nl now resets numbering for each page section rather than just for each page.
[This bug was present in "the beginning".]
pr now handles specified separator strings containing tabs correctly.
Previously it would have output random data from memory.
[This bug was detected with ASAN and present in "the beginning".]
sort -h -k now works even in locales that use blank as thousands separator.
stty --help no longer outputs extraneous gettext header lines
for translated languages. [bug introduced in coreutils-8.24]
stty "sane" again sets "susp" to ^z on Solaris, and leaves "swtch" undefined.
[This bug previously fixed only on some older Solaris systems]
seq now immediately exits upon write errors.
[This bug was present in "the beginning".]
tac no longer crashes when there are issues reading from non-seekable inputs.
[bug introduced in coreutils-8.15]
tail -F now continues to process initially untailable files that are replaced
by a tailable file. This was handled correctly when inotify was available,
and is now handled correctly in all cases.
[bug introduced in fileutils-4.0h]
tail -f - 'untailable file' will now terminate when there is no more data
to read from stdin. Previously it behaved as if --retry was specified.
[This bug was present in "the beginning".]
tail -f 'remote file' will now avoid outputting repeated data on network
file systems that misreport file sizes through stale metadata.
[This bug was present in "the beginning" but exacerbated in coreutils-8.24]
tail -f --retry 'missing file' will now process truncations of that file.
Previously truncation was ignored thus not outputting new data in the file.
[bug introduced in coreutils-5.3.0]
tail -f will no longer continually try to open inaccessible files,
only doing so if --retry is specified.
[This bug was present in "the beginning".]
yes now handles short writes, rather than assuming all writes complete.
[bug introduced in coreutils-8.24]
** Changes in behavior
rm no longer accepts shortened variants of the --no-preserve-root option.
seq no longer accepts 0 value as increment, and now also rejects NaN
values for any argument.
stat now outputs nanosecond information for time stamps even if
they are out of localtime range.
sort, tail, and uniq now support traditional usage like 'sort +2'
and 'tail +10' on systems conforming to POSIX 1003.1-2008 and later.
The 2008 edition of POSIX dropped the requirement that arguments
like '+2' must be treated as file names.
** Improvements
df now filters the system mount list more efficiently, with 20000
mount entries now being processed in about 1.1s compared to 1.7s.
du, shuf, sort, and uniq no longer fail to process a specified file
when their stdin is closed, which would have happened with glibc >= 2.14.
install -Z now also sets the default SELinux context for created directories.
ls is now fully responsive to signals until the first escape sequence is
written to a terminal.
ls now aligns quoted items with non quoted items, which is easier to read,
and also better indicates that the quote is not part of the actual name.
stat and tail now know about these file systems:
"balloon-kvm-fs" KVM dynamic RAM allocation support,
"cgroup2" Linux Control Groups V2 support,
"daxfs" Optical media file system,
"m1fs" A Plexistor file system,
"prl_fs" A parallels file system,
"smb2" Samba for SMB protocol V2,
"wslfs" Windows Subsystem for Linux,
"zsmalloc" Linux compressed swap support,
stat -f --format=%T now reports the file system type, and
tail -f uses polling for "prl_fs" and "smb2", and inotify for others.
stat --format=%N for quoting file names now honors the
same QUOTING_STYLE environment variable values as ls.
** New programs
b2sum is added to support the BLAKE2 digest algorithm with
a similar interface to the existing md5sum and sha1sum, etc. commands.
** New Features
comm now accepts the --total option to output a summary at the end.
date now accepts the --debug option, to annotate the parsed date string,
display timezone information, and warn about potential misuse.
date now accepts the %q format to output the quarter of the year.

Changelog:
* Noteworthy changes in release 8.25 (2016-01-20) [stable]
** Bug fixes
cp now correctly copies files with a hole at the end of the file,
and extents allocated beyond the apparent size of the file.
That combination resulted in the trailing hole not being reproduced.
[bug introduced in coreutils-8.10]
cut --fields no longer outputs extraneous characters on some uClibc configs.
[bug introduced in coreutils-6.11]
install -D again copies relative file names when absolute file names
are also specified along with an absolute destination directory name.
[bug introduced in coreutils-6.2]
ls no longer prematurely wraps lines when printing short file names.
[bug introduced in coreutils-5.1.0]
mv no longer causes data loss due to removing a source directory specified
multiple times, when that directory is also specified as the destination.
[bug introduced in coreutils-8.24]
shred again uses defined patterns for all iteration counts.
[bug introduced in coreutils-5.93]
sort --debug -b now correctly marks the matching extents for keys
that specify an offset for the first field.
[bug introduced with the --debug feature in coreutils-8.6]
tail -F now works with initially non existent files on a remote file system.
[bug introduced in coreutils-7.5]
** New commands
base32 is added to complement the existing base64 command,
and encodes and decodes printable text as per RFC 4648.
** New features
comm,cut,head,numfmt,paste,tail now have the -z,--zero-terminated option, and
tac --separator accepts an empty argument, to work with NUL delimited items.
dd now summarizes sizes in --human-readable format too, not just --si.
E.g., "3441325000 bytes (3.4 GB, 3.2 GiB) copied". It omits the summaries
if they would not provide useful information, e.g., "3 bytes copied".
Its status=progress output now uses the same format as ordinary status,
perhaps with trailing spaces to erase previous progress output.
md5sum now supports the --ignore-missing option to allow
verifying a subset of files given a larger list of checksums.
This also affects sha1sum, sha224sum, sha256sum, sha384sum and sha512sum.
printf now supports the '%q' format to print arguments in a form that
is reusable by most shells, with non-printable characters escaped
with the POSIX proposed $'...' syntax.
stty now supports the "[-]drain" setting to control whether to wait
for transmission of pending output before application of settings.
** Changes in behavior
base64 no longer supports hex or oct --wrap parameters,
thus better supporting decimals with leading zeros.
date --iso-8601 now uses +00:00 timezone format rather than +0000.
The standard states to use this "extended" format throughout a timestamp.
df now prefers sources towards the root of a device when
eliding duplicate bind mounted entries.
ls now quotes file names unambiguously and appropriate for use in a shell,
when outputting to a terminal.
join, sort, uniq with --zero-terminated, now treat '\n' as a field delimiter.
** Improvements
All utilities now quote user supplied arguments in error strings,
which avoids confusing error messages in the presence of '\r' chars etc.
Utilities that traverse directories, like chmod, cp, and rm etc., will operate
more efficiently on XFS through the use of "leaf optimization".
md5sum now ensures a single line per file for status on standard output,
by using a '\' at the start of the line, and replacing any newlines with '\n'.
This also affects sha1sum, sha224sum, sha256sum, sha384sum and sha512sum.
dircolors now supports globbing of TERM entries in its database.
For example "TERM *256color*" is now supported.
du no longer stats all mount points at startup, only doing so
upon detection of a directory cycle.
[issue introduced in coreutils-8.20]
ls -w0 is now interpreted as no limit on the length of the outputted line.
stat -f --format=%T now reports the file system type for new Linux
pseudo file systems "bpf_fs", "btrfs_test", "nsfs", "overlayfs"
and "tracefs", and remote file system "acfs".
wc now ensures a single line per file for counts on standard output,
by quoting names containing '\n' characters; appropriate for use in a shell.
* Noteworthy changes in release 8.24 (2015-07-03) [stable]
** Bug fixes
dd supports more robust SIGINFO/SIGUSR1 handling for outputting statistics.
Previously those signals may have inadvertently terminated the process.
df --local no longer hangs with inaccessible remote mounts.
[bug introduced in coreutils-8.21]
du now silently ignores all directory cycles due to bind mounts.
Previously it would issue a warning and exit with a failure status.
[bug introduced in coreutils-8.1 and partially fixed in coreutils-8.23]
chroot again calls chroot(DIR) and chdir("/"), even if DIR is "/".
This handles separate bind mounted "/" trees, and environments
depending on the implicit chdir("/").
[bugs introduced in coreutils-8.23]
cp no longer issues an incorrect warning about directory hardlinks when a
source directory is specified multiple times. Now, consistent with other
file types, a warning is issued for source directories with duplicate names,
or with -H the directory is copied again using the symlink name.
factor avoids writing partial lines, thus supporting parallel operation.
[the bug dates back to the initial implementation]
head, od, split, tac, tail, and wc no longer mishandle input from files in
/proc and /sys file systems that report somewhat-incorrect file sizes.
mkdir --parents -Z now correctly sets the context for the last component,
even if the parent directory exists and has a different default context.
[bug introduced with the -Z restorecon functionality in coreutils-8.22]
numfmt no longer outputs incorrect overflowed values seen with certain
large numbers, or with numbers with increased precision.
[bug introduced when numfmt was added in coreutils-8.21]
numfmt now handles leading zeros correctly, not counting them when
settings processing limits, and making them optional with floating point.
[bug introduced when numfmt was added in coreutils-8.21]
paste no longer truncates output for large input files. This would happen
for example with files larger than 4GiB on 32 bit systems with a '\n'
character at the 4GiB position.
[the bug dates back to the initial implementation]
rm indicates the correct number of arguments in its confirmation prompt,
on all platforms. [bug introduced in coreutils-8.22]
shuf -i with a single redundant operand, would crash instead of issuing
a diagnostic. [bug introduced in coreutils-8.22]
tail releases inotify resources when unused. Previously it could exhaust
resources with many files, or with -F if files were replaced many times.
[bug introduced in coreutils-7.5]
tail -f again follows changes to a file after it's renamed.
[bug introduced in coreutils-7.5]
tail --follow no longer misses changes to files if those files were
replaced before inotify watches were created.
[bug introduced in coreutils-7.5]
tail --follow consistently outputs all data for a truncated file.
[bug introduced in the beginning]
tail --follow=name correctly outputs headers for multiple files
when those files are being created or renamed.
[bug introduced in coreutils-7.5]
** New features
chroot accepts the new --skip-chdir option to not change the working directory
to "/" after changing into the chroot(2) jail, thus retaining the current wor-
king directory. The new option is only permitted if the new root directory is
the old "/", and therefore is useful with the --group and --userspec options.
dd accepts a new status=progress level to print data transfer statistics
on stderr approximately every second.
numfmt can now process multiple fields with field range specifications similar
to cut, and supports setting the output precision with the --format option.
split accepts a new --separator option to select a record separator character
other than the default newline character.
stty allows setting the "extproc" option where supported, which is
a useful setting with high latency links.
sync no longer ignores arguments, and syncs each specified file, or with the
--file-system option, the file systems associated with each specified file.
tee accepts a new --output-error option to control operation with pipes
and output errors in general.
** Changes in behavior
df no longer suppresses separate exports of the same remote device, as
these are generally explicitly mounted. The --total option does still
suppress duplicate remote file systems.
[suppression was introduced in coreutils-8.21]
mv no longer supports moving a file to a hardlink, instead issuing an error.
The implementation was susceptible to races in the presence of multiple mv
instances, which could result in both hardlinks being deleted. Also on case
insensitive file systems like HFS, mv would just remove a hardlinked 'file'
if called like `mv file File`. The feature was added in coreutils-5.0.1.
numfmt --from-unit and --to-unit options now interpret suffixes as SI units,
and IEC (power of 2) units are now specified by appending 'i'.
tee will exit early if there are no more writable outputs.
tee does not treat the file operand '-' as meaning standard output any longer,
for better conformance to POSIX. This feature was added in coreutils-5.3.0.
timeout --foreground no longer sends SIGCONT to the monitored process,
which was seen to cause intermittent issues with GDB for example.
** Improvements
cp,install,mv will convert smaller runs of NULs in the input to holes,
and cp --sparse=always avoids speculative preallocation on XFS for example.
cp will read sparse files more efficiently when the destination is a
non regular file. For example when copying a disk image to a device node.
mv will try a reflink before falling back to a standard copy, which is
more efficient when moving files across BTRFS subvolume boundaries.
stat and tail now know about IBRIX. stat -f --format=%T now reports the file
system type, and tail -f uses polling for files on IBRIX file systems.
wc -l processes short lines much more efficiently.
References from --help and the man pages of utilities have been corrected
in various cases, and more direct links to the corresponding online
documentation are provided.

* Noteworthy changes in release 8.23 (2014-07-18) [stable]
** Bug fixes
chmod -Rc no longer issues erroneous warnings for files with special bits set.
[bug introduced in coreutils-6.0]
cp -a, mv, and install --preserve-context, once again set the correct SELinux
context for existing directories in the destination. Previously they set
the context of an existing directory to that of its last copied descendent.
[bug introduced in coreutils-8.22]
cp -a, mv, and install --preserve-context, no longer seg fault when running
with SELinux enabled, when copying from file systems that return an error
when reading the SELinux context for a file.
[bug introduced in coreutils-8.22]
cp -a and mv now preserve xattrs of symlinks copied across file systems.
[bug introduced with extended attribute preservation feature in coreutils-7.1]
date could crash or go into an infinite loop when parsing a malformed TZ="".
[bug introduced with the --date='TZ="" ..' parsing feature in coreutils-5.3.0]
dd's ASCII and EBCDIC conversions were incompatible with common practice and
with POSIX, and have been corrected as follows. First, conv=ascii now
implies conv=unblock, and conv=ebcdic and conv=ibm now imply conv=block.
Second, the translation tables for dd conv=ascii and conv=ebcdic have been
corrected as shown in the following table, where A is the ASCII value, W is
the old, wrong EBCDIC value, and E is the new, corrected EBCDIC value; all
values are in octal.
A W E

[These dd bugs were present in "the beginning".]
df has more fixes related to the newer dynamic representation of file systems:
Duplicates are elided for virtual file systems like tmpfs.
Details for the correct device are output for points mounted multiple times.
Placeholder values are output for inaccessible file systems, rather than
than error messages or values for the wrong file system.
[These bugs were present in "the beginning".]
df now outputs all appropriate entries in the presence of bind mounts.
On some systems, entries would have been incorrectly elided due to
them being considered "dummy" mounts.
[bug introduced in coreutils-8.22]
du now silently ignores directory cycles introduced with bind mounts.
Previously it would issue a warning and exit with a failure status.
[bug introduced in coreutils-8.1]
head --bytes=-N and --lines=-N now handles devices more
consistently, not ignoring data from virtual devices like /dev/zero,
or on BSD systems data from tty devices.
[bug introduced in coreutils-5.0.1]
head --bytes=-N - no longer fails with a bogus diagnostic when stdin's
seek pointer is not at the beginning.
[bug introduced with the --bytes=-N feature in coreutils-5.0.1]
head --lines=-0, when the input does not contain a trailing '\n',
now copies all input to stdout. Previously nothing was output in this case.
[bug introduced with the --lines=-N feature in coreutils-5.0.1]
id, when invoked with no user name argument, now prints the correct group ID.
Previously, in the default output format, it would print the default group ID
in the password database, which may be neither real nor effective. For e.g.,
when run set-GID, or when the database changes outside the current session.
[bug introduced in coreutils-8.1]
ln -sf now replaces symbolic links whose targets can't exist. Previously
it would display an error, requiring --no-dereference to avoid the issue.
[bug introduced in coreutils-5.3.0]
ln -sr '' F no longer segfaults. Now works as expected.
[bug introduced with the --relative feature in coreutils-8.16]
numfmt now handles blanks correctly in all unibyte locales. Previously
in locales where character 0xA0 is a blank, numfmt would mishandle it.
[bug introduced when numfmt was added in coreutils-8.21]
ptx --format long option parsing no longer falls through into the --help case.
[bug introduced in TEXTUTILS-1_22i]
ptx now consistently trims whitespace when processing multiple files.
[This bug was present in "the beginning".]
seq again generates correct output with start or end values = -0.
[bug introduced in coreutils-8.20.]
shuf --repeat no longer dumps core if the input is empty.
[bug introduced with the --repeat feature in coreutils-8.22]
sort when using multiple threads now avoids undefined behavior with mutex
destruction, which could cause deadlocks on some implementations.
[bug introduced in coreutils-8.6]
tail -f now uses polling mode for VXFS to cater for its clustered mode.
[bug introduced with inotify support added in coreutils-7.5]
** New features
od accepts a new option: --endian=TYPE to handle inputs with different byte
orders, or to provide consistent output on systems with disparate endianness.
configure accepts the new option --enable-single-binary to build all the
selected programs in a single binary called "coreutils". The selected
programs can still be called directly using symlinks to "coreutils" or
shebangs with the option --coreutils-prog= passed to this program. The
install behavior is determined by the option --enable-single-binary=symlinks
or --enable-single-binary=shebangs (the default). With the symlinks option,
you can't make a second symlink to any program because that will change the
name of the called program, which is used by coreutils to determine the
desired program. The shebangs option doesn't suffer from this problem, but
the /proc/$pid/cmdline file might not be updated on all the platforms. The
functionality of each program is not affected but this single binary will
depend on all the required dynamic libraries even to run simple programs.
If you desire to build some tools outside the single binary file, you can
pass the option --enable-single-binary-exceptions=PROG_LIST with the comma
separated list of programs you want to build separately. This flag
considerably reduces the overall size of the installed binaries which makes
it suitable for embedded system.
** Changes in behavior
chroot with an argument of "/" no longer implicitly changes the current
directory to "/", allowing changing only user credentials for a command.
chroot --userspec will now unset supplemental groups associated with root,
and instead use the supplemental groups of the specified user.
cut -d$'\n' again outputs lines identified in the --fields list, having
not done so in v8.21 and v8.22. Note using this non portable functionality
will result in the delayed output of lines.
ls with none of LS_COLORS or COLORTERM environment variables set,
will now honor an empty or unknown TERM environment variable,
and not output colors even with --colors=always.
** Improvements
chroot has better --userspec and --group look-ups, with numeric IDs never
causing name look-up errors. Also look-ups are first done outside the chroot,
in case the look-up within the chroot fails due to library conflicts etc.
install now allows the combination of the -D and -t options.
numfmt supports zero padding of numbers using the standard printf
syntax of a leading zero, for example --format="%010f".
Also throughput was improved by up to 800% by avoiding redundant processing.
shred now supports multiple passes on GNU/Linux tape devices by rewinding
the tape before each pass, avoids redundant writes to empty files,
uses direct I/O for all passes where possible, and attempts to clear
inode storage used for small files on some file systems.
split avoids unnecessary input buffering, immediately writing input to output
which is significant with --filter or when writing to fifos or stdout etc.
stat and tail work better with HFS+, HFSX, LogFS and ConfigFS. stat -f
--format=%T now reports the file system type, and tail -f now uses inotify,
rather than the default of issuing a warning and reverting to polling.

GNU coreutils's configure script will abort if ran as root. Although
pkgsrc can do that step under an unprivilegied user, there are still
situations, such as pkg_comp bulk builds, where the common usage is
to run as root. We therefore override configure's root check by setting
FORCE_UNSAFE_CONFIGURE in the environement.

Fixes build failure on NetBSD-6.

Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

not use libtool to do so. This is required to correctly depend upon a

There have been 195 commits by 32 people in the 10 months since 8.21
Executive summary: 8.22 is mainly a bug fix and performance improvement release.
tail(1) has fixes for handling initially non existent files, and df now has
better handling of specified disk device nodes. On the performance side,
there have been many improvements to the memory usage of various tools, which
are detailed at http://www.pixelbeat.org/programming/avoiding_large_buffers.html
There have been large throughput improvements in cut(1) and base64 encoding.
Also the md5sum and sha*sum utilities have support for using architecture
specific routines to improve performance, if allowed on your distribution.
There are also new features available, including SELinux "restorecon" support
in various file creation utilities through the -Z option, and shred has a new
--repeat option to continually select random items from the input.
See the NEWS below for more details.

NEWS
* Noteworthy changes in release 8.22 (2013-12-13) [stable]
** Bug fixes
df now processes the mount list correctly in the presence of unstatable
mount points. Previously it may have failed to output some mount points.
[bug introduced in coreutils-8.21]
df now processes symbolic links and relative paths to special files containing
a mounted file system correctly. Previously df displayed the statistics about
the file system the file is stored on rather than the one inside.
[This bug was present in "the beginning".]
df now processes disk device nodes correctly in the presence of bind mounts.
Now df shows the base mounted file system rather than the last one mounted.
[This bug was present in "the beginning".]
install now removes the target file if the strip program failed for any
reason. Before, that file was left behind, sometimes even with wrong
permissions.
[This bug was present in "the beginning".]
ln --relative now updates existing symlinks correctly. Previously it based
the relative link on the dereferenced path of an existing link.
[This bug was introduced when --relative was added in coreutils-8.16.]
ls --recursive will no longer exit with "serious" exit code (2), if there
is an error reading a directory not specified on the command line.
[Bug introduced in coreutils-5.3.0]
mkdir, mkfifo, and mknod now work better when creating a file in a directory
with a default ACL whose umask disagrees with the process's umask, on a
system such as GNU/Linux where directory ACL umasks override process umasks.
[bug introduced in coreutils-6.0]
mv will now replace empty directories in the destination with directories
from the source, when copying across file systems.
[This bug was present in "the beginning".]
od -wN with N larger than 64K on a system with 32-bit size_t would
print approximately 2*N bytes of extraneous padding.
[Bug introduced in coreutils-7.0]
rm -I now prompts for confirmation before removing a write protected file.
[Bug introduced in coreutils-6.8]
shred once again uses direct I/O on systems requiring aligned buffers.
Also direct I/O failures for odd sized writes at end of file are now handled.
[The "last write" bug was introduced in coreutils-5.3.0 but masked
by the alignment bug introduced in coreutils-6.0]
tail --retry -f now waits for the files specified to appear. Before, tail
would immediately exit when such a file is initially inaccessible.
[This bug was introduced when inotify support was added in coreutils-7.5]
tail -F has improved handling of symlinks. Previously tail didn't respond
to the symlink target (re)appearing after being (re)created.
[This bug was introduced when inotify support was added in coreutils-7.5]
** New features
cp, install, mkdir, mknod, mkfifo and mv now support "restorecon"
functionality through the -Z option, to set the SELinux context
appropriate for the new item location in the file system.
csplit accepts a new option: --suppressed-matched, to elide the lines
used to identify the split points.
df --output now accepts a 'file' field, to propagate a specified
command line argument through to the output.
du accepts a new option: --inodes to show the number of inodes instead
of the blocks used.
id accepts a new option: --zero (-z) to delimit the output entries by
a NUL instead of a white space character.
id and ls with -Z report the SMACK security context where available.
mkdir, mkfifo and mknod with -Z set the SMACK context where available.
id can now lookup by user ID, in addition to the existing name lookup.
join accepts a new option: --zero-terminated (-z). As with the sort,uniq
option of the same name, this makes join consume and produce NUL-terminated
lines rather than newline-terminated lines.
uniq accepts a new option: --group to print all items, while separating
unique groups with empty lines.
shred accepts new parameters to the --remove option to give greater
control over that operation, which can greatly reduce sync overhead.
shuf accepts a new option: --repeat (-r), which can repeat items in
the output.
** Changes in behavior
cp --link now dereferences a symbolic link as source before creating the
hard link in the destination unless the -P,--no-deref option is specified.
Previously, it would create a hard link of the symbolic link, even when
the dereferencing options -L or -H were specified.
cp, install, mkdir, mknod and mkfifo no longer accept an argument to the
short -Z option. The --context equivalent still takes an optional argument.
dd status=none now suppresses all non fatal diagnostic messages,
not just the transfer counts.
df no longer accepts the long-obsolescent --megabytes option.
stdbuf now requires at least one buffering mode option to be specified,
as per the documented interface.
** Improvements
base64 encoding throughput for bulk data is increased by about 60%.
md5sum can use libcrypto hash routines where allowed to potentially
get better performance through using more system specific logic.
sha1sum for example has improved throughput by 40% on an i3-2310M.
This also affects sha1sum, sha224sum, sha256sum, sha384sum and sha512sum.
stat and tail work better with EFIVARFS, EXOFS, F2FS, HOSTFS, SMACKFS, SNFS
and UBIFS. stat -f --format=%T now reports the file system type, and tail -f
now uses inotify for files on all those except SNFS, rather than the default
(for unknown file system types) of issuing a warning and reverting to polling.
shuf outputs subsets of large inputs much more efficiently.
Reservoir sampling is used to limit memory usage based on the number of
outputs, rather than the number of inputs.
shred increases the default write block size from 12KiB to 64KiB
to align with other utilities and reduce the system call overhead.
split --line-bytes=SIZE, now only allocates memory as needed rather
than allocating SIZE bytes at program start.
stty now supports configuring "stick" (mark/space) parity where available.
** Build-related
factor now builds on aarch64 based systems [bug introduced in coreutils-8.20]
