The
df
utility
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 block counts are displayed with an assumed block size of
512 bytes.
If neither a file or a file system operand is specified,
statistics for all mounted file systems are displayed
(subject to the
-t
option below).
The following options are available:
|
| --libxo
|
| |
Generate output via
libxo(3)
in a selection of different human and machine readable formats.
See
xo_parse_args(3)
for details on command line arguments.
|
| -a
|
| |
Show all mount points, including those that were mounted with the
MNT_IGNORE
flag.
This is implied for file systems specified on the command line.
|
| -b
|
| |
Explicitly use 512 byte blocks, overriding any
BLOCKSIZE
specification from the environment.
This is the same as the
-P
option.
The
-k
option overrides this option.
|
| -c
|
| |
Display a grand total.
|
| -g
|
| |
Use 1073741824 byte (1 Gibibyte) blocks rather than the default.
This overrides any
BLOCKSIZE
specification from the environment.
|
| -h
|
| |
"Human-readable"
output.
Use unit suffixes: Byte, Kibibyte, Mebibyte, Gibibyte, Tebibyte and
Pebibyte (based on powers of 1024) in order to reduce the number of
digits to four or fewer.
|
| -H -, -si
|
| |
"Human-readable"
output.
Use unit suffixes: Byte, Kilobyte, Megabyte,
Gigabyte, Terabyte and Petabyte (based on powers of 1000) in order to
reduce the number of
digits to four or fewer.
|
| -i
|
| |
Include statistics on the number of free and used inodes.
In conjunction with the
-h
or
-H
options, the number of inodes is scaled by powers of 1000.
|
| -k
|
| |
Use 1024 byte (1 Kibibyte) blocks rather than the default.
This overrides the
-P
option and any
BLOCKSIZE
specification from the environment.
|
| -l
|
| |
Only display information about locally-mounted file systems.
|
| -m
|
| |
Use 1048576 byte (1 Mebibyte) blocks rather than the default.
This overrides any
BLOCKSIZE
specification from the environment.
|
| -n
|
| |
Print out the previously obtained statistics from the file systems.
This option should be used if it is possible that one or more
file systems are in a state such that they will not be able to provide
statistics without a long delay.
When this option is specified,
df
will not request new statistics from the file systems, but will respond
with the possibly stale statistics that were previously obtained.
|
| -P
|
| |
Explicitly use 512 byte blocks, overriding any
BLOCKSIZE
specification from the environment.
This is the same as the
-b
option.
The
-k
option overrides this option.
|
| -t
|
| |
Only print out statistics for file systems of the specified types.
More than one type may be specified in a comma separated list.
The list of file system types can be prefixed with
"no"
to specify the file system types for which action should
not
be taken.
For example, the
df
command:
df -t nonfs,nullfs
lists all file systems except those of type
NFS
and
NULLFS.
The
lsvfs(1)
command can be used to find out the types of file systems
that are available on the system.
|
| -T
|
| |
Include file system type.
|
| -,
|
| |
(Comma) Print sizes grouped and separated by thousands using the
non-monetary separator returned by
localeconv(3),
typically a comma or period.
If no locale is set, or the locale does not have a non-monetary separator, this
option has no effect.
