DF 1 ""
C 4 NAME
df - disk free
SYNOPSIS
df [
-ikn ] [ file | filesystem ... ]
DESCRIPTION
Df displays statistics on the amount of free disk space on the
filesystem
filesystem or on the filesystem of which
file is a part.
If neither a file or a filesystem 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 reported numbers are in 512-byte blocks. This causes the numbers to be reported in kilobytes.
-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.
