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.

since it's already included from sys2.h via system.h.
|
|
`exit (1)' to `exit (EXIT_FAILURE)', and
`usage (1)' to `usage (EXIT_FAILURE)'.
|
|
its heading, even when -P is used with -h or -H.
|
|
This fixes a bug where df would report Size < Used.
(df_readable): Omit last arg; we always round up now.
All callers changed.
|
|
|
|
(long_options, usage, main): Add -B.
(usage): Deprecate --kilobytes, -m, --megabytes.
Document size suffixes.
(print_header, show_dev): Enlarge column widths for trailing "B".
|
|
instead of hard-coding --help and --version descriptions.
|
|
for short options too.''
|
|
Use fputs, not printf.
|
|
[HAVE_RESOLVEPATH], [!HAVE_RESOLVEPATH]: Use malloc, not alloca,
so that these two paths also produce `resolved' in malloc'd storage.
Free that memory when done with it.
|
|
(find_mount_point): No need to strip trailing
slashes before invoking new dir_name.
|
|
the mount directory exists and has the required device number.
Before, e.g., `df /floppy' would mistakenly report on the root
partition if /floppy were not listed in /etc/mtab but / was.
Patch from Eirik Fuller (http://bugs.debian.org/76923).

corresponding argument in a `quote (...)' call.
|
|
Use integer arithmetic if it's easy.
Fix bug when converting twos-complement negative values to floating point.
|
|
Round negative numbers correctly.
(show_dev): Round disk usage up and disk free space down.
|
|
Cast undeclared `realpath' to char* to avoid warning.
|
|
|
|
prefixes that are loop file system mount points, since they
yield undesirable output.
|
|
Print the header line only if there is at least one valid argument.

|
|
(path-concat.h): Include.
(show_point): If HAVE_REALPATH or HAVE_RESOLVEPATH is defined,
find the real absolute path for PATH, and use that to find the
mount point.
(show_point): Prefer non-dummy entries in shortcuts, too.
Disable bogus mount dirs instead of restatting them each time.
|
|
(show_dev): Avoid overflow problems when calculating percent.
Do not display negative percents.
|
|
these and use them instead of `CHAR_MAX + n'.
|
|
New arg NEGATIVE.
(ceil_percent): Now returns double, not int.
Be more careful about adding 1 to a wild value.
(show_dev): Don't filter out wild sizes from the underlying operating
system; instead, show them to the user as faithfully as possible.
|
|
|
|
Use IF_LINT macro instead of #ifdef lint...
|
|
(df_readable): Take ceiling if posix_format.
(ceil_percent): New function.
(show_dev): Take ceiling of percent if posix_format.
Align with POSIX-conforming header if posix_format.
|
|
just warn rather than failing if the table of mounted filesystems
cannot be read.
|
|
via sys2.h.
|
|
Include version-etc.h instead.
(PROGRAM_NAME, AUTHORS): Define.
[long_options]: Add entries for --help and --version.
Remove parse_long_options call.
(main) [getopt switch]: Add a case for each of --help and --version.
|
|
[long_options]: Remove the "help" and "version" entries.
(main): Use parse_long_options, including author name(s).
Remove the show_version and show_help blocks.

let the device path and the file system type share a single (wider)
field if their combined lengths allow it. From Andries Brouwer.
|

|

Revert to boolean value; the old negative value is
now in show_local_fs.
(show_local_fs): New variable.
(show_dev): New args me_dummy and me_class. Use show_local_fs
and boolean show_all_fs in combination with these new args
to decide whether to show a device.
(show_disk): Pass flags to show_dev.
(show_point): Use a non-dummy mount entry if possible.
(show_all_entries): Pass flags to show_dev.
(main): --local sets show_local_fs now. Ask for file system types if
show_local_fs is nonzero, since ME_REMOTE might need them.
From Paul.

{"all", no_argument, &show_all_fs, 1},
but rather this form:
{"all", no_argument, NULL, 'a'},
Using the latter, all the option handling in one place: the getopt loop.
|
|
(show_all_fs): If negative, omit non-local filesystems.
All uses of (all_fs != 0) changed to (all_fs > 0).
(long_options, usage, main): Add -l or --local option.
(main): When asking for df of an explicit file name, get all
the mount points, so that we're more likely to find it when
we look it up.

up out of if-block -- code in the else-block depends on it too.

replace with new variable output_block_size. All uses changed.
(long_options, usage, main): Add --block-size.
(main, decode_switches): Use new human_block_size function to
initialize output block size consistently with other programs.
(print_header, show_dev): Shrink some columns and expand
others, to squeeze in support for today's larger filesystems.
(print_header): Print output block size using power-of-1024 SI format.
(df_readable): Coalesce last two args into one, for convenience.
All callers changed.
(main): Remove check for portable output format and larger
or human-readable block sizes.
From Paul Eggert.
