* doc/coreutils.texi (mv invocation): Add a sentence to clarify that
mv(1) will only replace empty directories in the target, and fail with
a diagnostic otherwise. Discussed at:

The character 'K' representing numeric user input can be confusing,
especially in the context where it can be suffixed by the multipliers
K, M, G, etc.
Use NUM instead.
* doc/coreutils.texi (head invocation): Replace @var{k} by @var{num}.
Also change @var{count} in the paragraph about the obsolete option
syntax.
(tail invocation): Likewise. Furthermore, adjust the option order to
alphabetical sorting.
* src/head.c (usage): s/K/NUM/ in as placeholder in the -c and -n
options. Furthermore, print the actual DEFAULT_NUMBER instead of the
hard-coded 10.
* src/tail.c (usage): s/K/NUM/ in as placeholder in the -c and -n
options. Add "[+]" to clarify that NUM may optionally be preceded by
this sign. Remove the redundant explanation of the optional '+' prefix
for NUM, as that is now clear from the option description above.

* doc/local.mk (constants.texi): Avoid calling makeinfo unless
the constants derived from tail and shred have changed.
This avoids a dependence on makeinfo from patched sources,
and avoids an expensive makeinfo call for developers.
|
|
* doc/coreutils.texi (uniq invocation): Fix the description of
problematic input to say "blank lines" rather than "two or more
blank lines".
(tr invocation): Clarify that -s only works with SET1 when
not translating (when SET2 not specified). Also explicitly
state in examples where blank lines are deleted.
Also add "deleting" to the menu item.
* src/tr.c (usage): Improve the -s summary to say it always
operates on the last specified SET.

* doc/coreutils.texi (tail invocation): Provide an example using awk
to convert tail ==> file <== headers to file: prefixes on each line.

* doc/coreutils.texi (du invocation): Remove 'like' from
mentions of ISO-8601 as the components are individually conformant.
(ls invocation): Likewise, except for --time-style=iso for recent
files, where the MM-DD component is not a valid ISO-8601 timestamp.
|
|
* src/date.c (main): Use %:z rather than %z with --iso-8601
as the standard states to consistently use extended format.

It was a little confusing as to whether the SQUFOF algorithm was
enabled, and in fact there were no options available to enable it.
Therefore clarify the 3 configurable behaviors for the code to
3 defines at the top of the program, and only include the SQUFOF
code if enabled at compile time.
$ size src/factor-before
text data bss
93997 1412 2504
$ size src/factor-after
text data bss
87885 1404 2504
* src/factor.c: Only include the SQUFOF factor code
when enabled via the USE_SQUFOF define.
* doc/coreutils.texi (factor invocation): Update note about
factor limits, as we can factor 128 bit numbers without GMP.

sha512sum can be faster than sha256sum.
E.g., ‘dd if=/dev/zero bs=1024k count=1024 | time sha256sum’
reports 8.16 user CPU seconds on my host, whereas sha512sum
consumes 5.45 seconds (Fedora x86-64 on an AMD Phenom II X4 910e).
Although sha512sum is still considerably slower on x86, a good
chunk of uses are on 64-bit hosts and anyway there’s little point
to scaring people away from sha512sum nowadays.
* doc/coreutils.texi (sha2 utilities): Remove obsolete comment.

* src/numfmt.c: Replace field handling code with logic that understands
field range specifiers. Instead of processing a single field and
printing line prefix/suffix around it, process each field in the line
checking whether it has been included for conversion. If so convert and
print, otherwise just print the unaltered field.

* src/numfmt.c (unit_to_umax): Support SI (power of 10) suffixes
with the --from-unit and --to-unit options. Treat suffixes like
is done with --from=auto, which for example will change the meaning
of --to-unit=G to that of --to-unit=Gi. The suffix support was
previously undocumented and it's better to avoid the traditional
coreutils suffix handling in numfmt by default.

tee is very often used with pipes and this gives better control
when writing to them. There are 3 classes of file descriptors
that tee can write to: files(1), pipes(2), and early close pipes(3).
Handling write errors to 1 & 2 is supported at present with the caveat
that failure writing to any pipe will terminate tee immediately.
Handling write errors to type 3 is not currently supported.
To improve the supported combinations we add these options:
--write-error=warn
Warn if error writing any output including pipes.
Allows continued writing to still open files/pipes.
Exit status is failure if any output had error.
--write-error=warn-nopipe, -p
Warn if error writing any output except pipes.
Allows continued writing to still open files/pipes.
Exit status is failure if any non pipe output had error.
--write-error=exit
Exit if error writing any output including pipes.
--write-error=exit-nopipe
Exit if error writing any output except pipes.
Use the "nopipe" variants when files are of types 1 and 3, otherwise
use the standard variants with types 1 and 2. A caveat with the above
scheme is that a combination of pipe types (2 & 3) is not supported
robustly. I.e. if you use the "nopipe" variants when using both type
2 and 3 pipes, then any "real" errors on type 2 pipes will not be
diagnosed.
Note also a general issue with type 3 pipes that are not on tee's
stdout, is that shell constructs don't allow to distinguish early
close from real failures. For example `tee >(head -n1) | grep -m1 ..`
can't distinguish between an error or an early close in "head" pipe,
while the fail on the grep part of the pipe is distinguished
independently from the resulting pipe errors. This is a general
issue with the >() construct, rather than with tee itself.
* NEWS: Mention the new feature.
* doc/coreutils.texi (tee invocation): Describe the new option.
* src/tee.c (usage): Likewise.
(main): With --write-error ignore SIGPIPE, and handle
the various exit, diagnostics combinations.
* tests/misc/tee.sh: Tess all the new options.

Since v5.2.1-1247-g8dafbe5, tee(1) treated '-' as stdout while POSIX
explicitly requires to treat this as a file name. Revert this change,
as the interleaved output - due to sending another copy of input to
stdout - is not considered to be useful. Discussed in

To align with all other places (and correct grammar), change all
upper-case "I.E." to "I.e.". Furthermore, ensure that "i.e." is

old ChangeLog files):

The equivalent of this is 'flush', but that was never documented

the more descriptive name, also generally used on BSD systems.
Note even though this setting seems ineffective on Linux, supporting
the setting is useful to allow terminal programs to receive
