df
displays statistics about the amount of free disk
space on the specified file_system or on the file system
of which file is a part. By default, all sizes are
reported in 512-byte block counts. If neither a file or a
file_system operand is specified, statistics for all
mounted file systems are displayed (subject to the -l
and -t
options below).
Note that the printed count of available blocks takes minfree into account, and thus will be negative when the number of free blocks on the filesystem is less than minfree.
The following options are available:
-a
MNT_IGNORE
flag.-G
-i
or
-P
options, and it is modelled after the Solaris
-g
option. This option will override the
-g
, -h
,
-k
, and -m
options, as
well as any setting of BLOCKSIZE
.-g
-g
option causes the numbers to be reported in
gigabytes (1024*1024*1024 bytes).-h
-i
-k
-k
option causes the numbers to be reported in
kilobytes (1024 bytes).-l
MNT_LOCAL
flag set. If a non-local file system is
given as an argument, a warning is issued and no information is given on
that file system.-m
-m
option causes the numbers to be reported in
megabytes (1024*1024 bytes).-n
df
will
not request new statistics from the file systems, but will respond with
the possibly stale statistics that were previously obtained.-P
If both the -P
and
-k
option are specified, the output will be
preceded by the following header line, formatted to match the data
following it:
"Filesystem 1024-blocks Used Available Capacity Mounted on\n"
If the -P
option is specified without
the -k
options, the output will be preceded by
the following header line, formatted to match the data following it:
"Filesystem <blksize>-blocks Used Available Capacity Mounted on\n"
The header line is followed by data formatted as follows:
"%s %d %d %d %d%% %s\n", <file system name>, <total space>, <space used>, <space free>, <percentage used>, <file system root>
Note that the -i
option may not be
specified with -P
.
-t
typeBLOCKSIZE
BLOCKSIZE
is set, and
the -g
, -h
,
-k
and -m
options are not
specified, the block counts will be displayed in units of that size
