NAME
df
- display free disk space
SYNOPSIS
[-ikln
]
[-t type
]
[file | file_system ...
]
DESCRIPTION
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.
Values are displayed in 512-byte per block 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).
The following options are available:
- -i
-
Include statistics on the number of free inodes.
- -k
-
By default, all sizes are reported in 512-byte block counts.
The
-k
option causes the numbers to be reported in kilobyte counts.
- -l
-
Display statistics only about mounted file systems with the 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.
- -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,
will not request new statistics from the file systems, but will respond
with the possibly stale statistics that were previously obtained.
- -t type
-
Is used to indicate the actions should only be taken on
filesystems of the specified type.
More than one type may be specified in a comma separated list.
The list of filesystem types can be prefixed with
``no''
to specify the filesystem types for which action should
not
be taken. If a file system is given on the command line that is not of
the specified type, a warning is issued and no information is given on
that file system.
ENVIRONMENT VARIABLES
- BLOCKSIZE
-
If the environment variable
BLOCKSIZE
is set, and the
-k
option is not specified, the block counts will be displayed in units of that
size block.
