DF(1)                        BSD Reference Manual                        DF(1)

NAME
     df - display free disk space

SYNOPSIS
     df [-in] [file | filesystem ...]

DESCRIPTION
     Df displays statistics about the amount of free disk space on the speci-
     fied filesystem or on the filesystem of which file is a part.  Values are
     displayed in 512-byte per block block counts.  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.

     -n      Print out the previously obtained statistics from the filesys-
             tems.  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 filesys-
             tems, but will respond with the possibly stale statistics that
             were previously obtained.

ENVIRONMENTAL VARIABLES
     BLOCKSIZE  If the environmental variable BLOCKSIZE is set, the block
                counts will be displayed in units of that size block.

BUGS
     The -n flag is ignored if a file or filesystem is specified.
