NAME
df
- display free disk space
SYNOPSIS
df
[-ikn
]
[file | filesystem ...
]
DESCRIPTION
Df displays statistics about the amount of free disk space on the specified
filesystem
or on the filesystem of which
file
is a part.
If neither a file or a filesystem operand is specified,
statistics for all mounted filesystems are displayed.
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.
- -n
-
Print out the previously obtained statistics from the filesystems.
This option should be used if it is possible that one or more
filesystems 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 filesystems, but will respond
with the possibly stale statistics that were previously obtained.
BUGS
The
-n
flag is ignored if a file or filesystem is specified.
