no output. This change was in 6.0 but inadvertently unmentioned.
* doc/coreutils.texi (df invocation): df exits nonzero if it outpus
nothing.
* src/df.c (file_systems_processed): Renamed from n_valid_args, and now
a boolean.
(show_dev): Don't set it until we actually output something.
Print the header if this is the first output.
(main): Don't print a header, as that is now show_dev's job.
* tests/misc/Makefile.am (TESTS): Add df.
* tests/misc/df: New file.
stat for a symlink, even though it wasn't always needed.
In some cases, that unnecessary stat would cause ls to fail.
* src/ls.c (gobble_file): Don't treat symlinks specially (in
requiring a stat syscall). Remove the offending exclusion.
* NEWS: Mention the fix.
* tests/ls/stat-dtype: New file/test, for the above fix.
Also exercises the new df feature, below.
of directories alone unless you specify them explicitly.
install and mkdir now implement X correctly.
install now creates parent directories with mode 755, without
changing their owner or group.
information if seq's operands are all fixed point decimal numbers.
You no longer need the `-f%.f' in `seq -f%.f 1048575 1024 1050623',
for example, since the default format now has the same effect.
seq now lets you use %a, %A, %E, %F, and %G formats.
seq now uses long double internally rather than double.
* src/remove.c (remove_cwd_entries): If we can't open a directory,
and the failure is not being ignored, try to remove the directory
with rmdir (aka unlinkat-with-AT_REMOVEDIR), in case it's empty.
Problem report and test case from Paul Eggert in
<http://article.gmane.org/gmane.comp.gnu.core-utils.bugs/7425>.
* tests/rm/empty-inacc: New test, for the above.
contains a list of NUL-separated file names.
* src/wc.c: Include "readtokens.h".
(usage): Describe the new option, and adjust the `Usage':
with this option, no FILE may be specified on the command line.
(main): Handle the new option.
* tests/misc/wc-files0: New tests, for the above.
* tests/misc/wc-files0-from: Likewise.
* tests/misc/Makefile.am (TESTS): Add wc-files0.
when applied to files in /proc and /sys, even when the FIONREAD
ioctl produces nonsensical results. Before this change, cat would
produce no output (or truncated output), for some linux kernels.
* src/cat.c (write_pending): New function, factored out of cat.
(cat): Also interpret a negative ioctl/FIONREAD count as indicating
that there are bytes to read. Some versions of linux-2.6.16 do that.
Write any pending output before returning.
Reported by Dan Jacobson in <http://bugs.debian.org/370583>.
* NEWS: Mention this bug fix.
* tests/misc/cat-proc: New file. Test for the above.
* tests/misc/Makefile.am (TESTS): Add cat-proc.
