* src/dd.c (parse_integer): Use recursion to support more than two
multipliers. Also protect suffix[-1] access to ensure we don't
inspect before the passed string.

* doc/coreutils.texi (dd invocation): Note the support for specifying
many multipliers in a number.
* NEWS: Mention the bug fix.
Fixes https://bugs.debian.org/1037275
* doc/coreutils.texi (od invocation): Remove mention of ASCII,
as all printable characters in unibyte locales are output.
* src/od.c (usage): Clarify that only NUL terminated strings
are displayed, and that it's printable chars, not only graphic chars
that are output. I.e., spaces are output also if part of the string.
Reported at https://bugs.ddebian.org/1037217
Add --update=none which is equivalent to the --no-clobber behavior
from before coreutils 9.2. I.e. existing files are unconditionally
skipped, and them not being replaced does not affect the exit status.
* src/copy.h [enum Update_type]: A new type to support parameters
to the --update command line option.
[enum Interactive]: Add I_ALWAYS_SKIP.
* src/copy.c: Treat I_ALWAYS_SKIP like I_ALWAYS_NO (-n),
except that we don't fail when skipping.
* src/system.h (emit_update_parameters_note): A new function
to output the description of the new --update parameters.
* src/cp.c (main): Parse --update arguments, ensuring that
-n takes precedence if specified.
(usage): Describe the new option. Also allude that
-u is related in the -n description.
* src/mv.c: Accept the new --update parameters and
update usage() accordingly.
* doc/coreutils.texi (cp invocation): Describe the new --update
parameters. Also reference --update from the --no-clobber description.

(input_file_size): Use it to split larger files when sizes cannot
easily be determined via fstat or lseek. See Bug#61386#235.

(lines_chunk_split, bytes_chunk_extract):
Be consistent with new byte_split.
* tests/split/b-chunk.sh, tests/split/l-chunk.sh: Test new behavior.
* src/tee.c (usage): Change from describing one (non pipe) aspect
to the more general point of being the option to use if working with
pipes, and referencing the more detailed info below.
* doc/coreutils.texi (tee invocation): s/standard/appropriate/ since
the standard operation with pipes is to exit immediately upon write
error. s/early/immediately/ as it's ambiguous as to what "early"
is in relation to.
If input is intermittent (a tty, pipe, or socket), and all remaining
outputs are pipes (eg, >(cmd) process substitutions), exit early when
they have all become broken pipes (and thus future writes will fail),
without waiting for more input to become available, as future write
attempts to these outputs will fail (SIGPIPE/EPIPE).
Only provide this enhancement when pipe errors are ignored (-p mode).
Note that only one output needs to be monitored at a time with iopoll(),
as we only want to exit early if _all_ outputs have been removed.
* src/tee.c (pipe_check): New global for iopoll mode.
(main): enable pipe_check for -p, as long as output_error ignores EPIPE,
and input is suitable for iopoll().
(get_next_out): Helper function for finding next valid output.
(fail_output, tee_files): Break out write failure/output removal logic
to helper function.
(tee_files): Add out_pollable array to track which outputs are suitable
for iopoll() (ie, that are pipes); track first output index that is
still valid; add iopoll() broken pipe detection before calling read(),
removing an output that becomes a broken pipe.
* src/local.mk (src_tee_SOURCES): include src/iopoll.c.
* NEWS: Mention tee -p enhancement in Improvements.
* doc/coreutils.texi: Mention the new early exit behavior in the nopipe
modes for the tee -p option.

How a file is copied is dependent on the sparseness of the file,
what file system it is on, what file system the destination is on,
the attributes of the file, and whether they're being copied or not.
Also the --reflink and --sparse options directly impact the operation.
Given it's hard to reason about the combination of all of the above,
the --debug option is useful for users to directly identify if
copy offloading, reflinking, or sparse detection are being used.
It will also be useful for tests to directly query if
these operations are supported.
The new output looks as follows:
$ src/cp --debug src/cp file.sparse
'src/cp' -> 'file.sparse'
copy offload: yes, reflink: unsupported, sparse detection: no
$ truncate -s+1M file.sparse
$ src/cp --debug file.sparse file.sparse.cp
'file.sparse' -> 'file.sparse.cp'
copy offload: yes, reflink: unsupported, sparse detection: SEEK_HOLE
$ src/cp --reflink=never --debug file.sparse file.sparse.cp
'file.sparse' -> 'file.sparse.cp'
copy offload: avoided, reflink: no, sparse detection: SEEK_HOLE

* src/cp.c: if ("--debug") x->debug=true;
* src/install.c: Likewise.
* src/mv.c: Likewise.
* tests/cp/debug.sh: Add a new test.
* tests/local.mk: Reference the new test.
* NEWS: Mention the new feature.
--raw output is the most composable format, and also is a
robust way to discard the file name without parsing (escaped) output.
Examples:
$ cksum --raw -a crc "$afile" | basenc --base16

$ cksum --raw -a crc "$afile" | basenc --base2msbf

Addresses https://bugs.gnu.org/59262
Problem reported by Antonio Diaz Diaz (bug#59262).
* doc/coreutils.texi: Use markup in menus to prevent
‘--’ from turning into an em dash, and to be more
consistent.
Note using iconv(1) rather than recode(1) is not appropriate
for this example, as the required functionality is only
available on libiconv's iconv implementation, which is
not installed on most systems.
* doc/coreutils.texi (printf invocation): Use env rather than
/usr/local/bin for the printf command. Escape '%' so more robust.
Also use a locale that exists on modern systems.
Previously this was restricted to the C99 universal character subset,
which restricted most values <= 0x9F, as that simplifies the C lexer.
However printf(1) doesn't need this restriction.
Note also the bash builtin printf already supports all values <= 0x9F.
* src/printf.c (main): Relax the restriction on points <= 0x9F.
* doc/coreutils.texi (printf invocation): Adjust description.
* tests/misc/printf-cov.pl: Adjust accordingly. Add new cases.
* NEWS: Mention the change in behavior.
Reported at https://bugs.debian.org/1022857
* doc/coreutils.texi (sort invocation): Mention in the
multi invocation sort example that the -V GNU extension
could be used to sort IPv4 addresses, and thus simplify
to a single invocation.
* src/system.h (emit_exec_status): A new function to
output standard "Exit status:" info for commands that exec others.
* doc/coreutils.texi (Exit status): Add "ls" and "runcon"
to the list of commands with non standard exit status.
* src/numfmt.c (main): Call initialize_exit_failure() explicitly
to better indicate this utility may exit with something other than
EXIT_FAILURE.
* src/timeout.c (usage): Use more consistent capitalization.
* src/chroot.c: Call emit_exec_status().
* src/env.c: Likewise.
* src/nice.c: Likewise.
* src/nohup.c: Likewise.

without this option, control of when the total is output
is quite awkward. Consider trying to suppress the total line,
which could be achieved with something like:
wc-no-total() { wc "$@" /dev/null | head -n-2; }
As well as being non obvious, it's also non general.
It would give a non failure, but zero count if passed a file on stdin.
Also it doesn't work in conjunction with the --files0-from option,
which would need to be handled differently with something like:
{ find files -print0; printf '%s\0' /dev/null; } |
wc --files0-from=- |
head -n2
Also getting just the total can be awkward as file names
are only suppressed when processing stdin, and
also a total line is only printed if processing more than one file.
For completness this might be achieved currently with:
wc-only-total() {
wc "$@" |
tail -n1 |
sed 's/^ *//; s/ [^ 0-9]*$//'
}
* src/wc.c: Add new --total option.
* tests/misc/wc-total.sh: New test suite for the new option.

* doc/coreutils.texi (wc invocation): Document the new option.
* THANKS.in: Add suggestor.
* NEWS: Mention the new feature.
* doc/coreutils.texi (stty invocation): Say that "drain"
is treated as an option, rather than a line setting,
and so option processing rules apply to it.
Reported in https://bugs.debian.org/1018803
* src/comm.c (compare_files): Handle the single character
--output-delimeter case separately so that NUL is appropriately
handled.
* doc/coreutils.texi (comm invocation): Fix the description
of --output-delimiter to say an empty delimeter is treated
as a NUL separator, rather than being disallowed.
* tests/misc/comm.pl: Add a test case.
Reported at https://bugs.debian.org/1014008
* src/runcon.c: Use EXIT_CANCELED (125) instead of EXIT_FAILURE (1),
so that errors specific to runcon can be distinguished,
from those of the invoked program.
* doc/coreutils.texi (runcon invocation): Fix the Exit status
description to say we return 125 (not 127) for internal errors.
* tests/misc/runcon-no-reorder.sh: Add a test case.
* src/ls.c (usage): Don't mention "modification" in the
description of ctime (-c), as it's confusing with mtime.
Mention "metadata" when discussing "change" time to
disambiguate from data change time.
* doc/coreutils.texi (ls invocation): State that --time=creation
falls back to using mtime where not available.
This behaviour is correctly documented when doing `cp --help`.
There is no `--reflink=when` option.
* doc/coreutils.texi (cp invocation): Fix document stating
that `--reflink` is equivalent to `--reflink=always`.
It's useful to treat empty and missing arguments differently.
Missing means all signals, while empty means no signals and
so is a no-op. It's useful to treat empty arguments like
this, so that dynamically specified arguments like the following
are supported
env --ignore-signals "$SIGS_TO_IGNORE"
Note `env --ignore-signals=` is treated as an empty argument.
* doc/coreutils.texi (env invocation): Empty args are treated
differently to missing arguments, so call that out explicitly.
* src/env.c (usage): Likewise.
Addresses https://bugs.debian.org/1016049
* src/date.c (usage): Specify that --date, --file, --reference,

documentation to group similar options.
