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.

and available columns from 7 to 8.

assume the original value corresponding to fsu_bavail was negative.

last column of `df -i' output. From Andreas Schwab.
|

with the rest of the output.
|
|
(show_dev): If a value consists entirely of 1 bits, or is derived
from some other value that consists entirely of 1 bits, report "-".
Check inode and block counts more carefully for plausibility,
to avoid arithmetic overflow when computing percentages.
|
|
Include "closeout.h".
|
|
just like `fsu.fsu_blocks == 0' as an indicator that usage information
is invalid. This happens with Solaris-5.5.1 CD-ROM partitions.

not e.g., -a) back up to precede first print stmt.

blocks_used etc. and blocks_percent_used,
inodes_used etc. and inodes_percent_used into respective branches
of the `if (inode_format)' statement where they're actually used.
|

("human.h"): Include.
(LONGEST_HUMAN_READABLE_1K_BYTE_BLOCKS): Remove.
(human_readable_base): Renamed from human_blocks; value is now
zero or positive integer, not just zero or nonzero.
(output_units): New variable;
replaces booleans kilobyte_blocks and megabyte_blocks.
(long_options): Add --si or -H.
(print_header): Adjust to renamed option variables.
(human_readable_1k_blocks): Remove.
(show_dev): Count blocks using uintmax_t, not long.
Calculate percentages using double, not long; this still isn't
perfect as it suffers double rounding, but it's more likely to
round correctly in practice than using long did.
Adjust to renamed option variables.
Use new human_readable library function to format uintmax_t values.
(usage): Add -H, --si.
(main): Adjust to renamed option variables.
Use -H if BLOCKSIZE is SI. Add -H.
