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.
file system is processed. This makes it easy to test whether
a specified directory is on a file system of a given type or types.
Otherwise, applications would have had to parse df's output.
E.g., is "." either ext3 or reiserfs: df -t ext3 -t reiserfs .
show_listed_fs, posix_format, require_sync, print_type,
selected_fstype, excluded_fstype, show_dev, show_point, main):
Use bool for booleans.
(df_readable, show_dev): Use UINTMAX_MAX instead of -1.
(show_dev, show_point, main):
Use EXIT_SUCCESS/EXIT_FAILURE instead of 0/1.
Don't assume disk name lengths are <= INT_MAX.
Rewrite pct calculation to avoid cast.
(show_point): Don't assume resolved length is <= SSIZE_MAX.
mounted on the same mount point, prefer the last one, not the first.
Problem reported by Christian Jones in
<http://mail.gnu.org/archive/html/bug-coreutils/2004-04/msg00200.html>.
(show_disk): Remove unused statp arg. Return bool, not int.
(show_point): Rewrite to avoid gotos. Use the same algorithm
for lofs and dummies for each pass through the mount table,
rather than subtly different algorithms (which are probably
inadvertent).
of 2003-09-19. Now, AUTHORS is a comma-separated list of strings.
Update the call to parse_long_options so that `AUTHORS, NULL' are the
last parameters.
* src/true.c (main): Append NULL to version_etc argument list.
* src/sys2.h (case_GETOPT_VERSION_CHAR): Likewise.
failed syscall, rather than relying on caller to do that.
The caller couldn't do a good job, anyhow -- too many different
ways to fail (each with a different referent).
Give a diagnostic upon failed save_cwd, now that that function
no longer calls `error'.
(show_point): Don't diagnose find_mount_point's errors, now that
it handles them itself.
listed mount point under `Filesystem'. Before, for an unmounted
block- or character-special file argument, it would display the
command-line argument instead.
(show_disk): Return a value indicating whether
there was a match. Don't try to find a mount point here.
(show_entry): If show_disk doesn't find a match, call show_point.
string of spaces matching the length of the English `...Type' header,
output the right number of spaces to match the selected translation.
Reported by Yann Dirson and Jean Charles Delepine as Debian bug 131113.
the name of the file system on which the file resides, usually `/'.
Before, it would leave the `Mounted on' field blank.
(show_disk): Add parameter: STATP.
If we don't find a matching device name, then resort to calling
find_mount_point.
human.h, to print large numbers simply.
(human_output_opts): New var.
(output_block_size): Now uintmax_t, not int, to handle larger
block sizes. All uses changed.
(print_header): In the header line, prefer SI to human
representation if it's shorter; if neither is shorter, try to
intuit what the user would prefer.
