NAME
	  DF - Display statistics on free disk space.

     SYNTAX
	  df [ -ikn ] [	-t type	] [ file | file_system ]

     ARGUMENTS
	  -i	    Includes statistics	on the number of free inodes.

	  -k	    Causes the numbers to be reported in kilobytes. By
		    default, all reported numbers are in 512-byte
		    blocks.

	  -n	    Prints out the previously obtained statistics from
		    all	mounted	file systems. Use this flag 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 (for example, a
		    remote file	system on a server that	has crashed).

		    When this flag is specified, df does not request
		    new	statistics from	the file systems; for some
		    remote file	systems, the statistics	displayed may
		    be too old to be useful.

	  -t type   Displays statistics	for the	specified file system
		    type only. If the -t flag is specified and a file
		    or filesystem is specified,	the -t flag is
		    ignored. Available file system types include the
		    following:

		      ufs	  UNIX File System (Berkeley Fast File
				  System) (default)

		      pfs	  Parallel File	System (PFS)

		      nfs	  Network File System

		    If the -t flag is specified	and a file or
		    file_system	argument is specified, the -t flag is
		    ignored.

	  file	    Pathname of	a file.

	  file_system
		    Pathname of	a mounted file system.

     DESCRIPTION
	  Using	the df command on a PFS	file system gives information
	  about	the single disk	partition on which the PFS file	system
	  is mounted. The df command does not give information about
	  how much cumulative space is actually	available for PFS file
	  striping. Use	the showfs command to get information about
	  the cumulative amount	of free	space in a PFS file system.

	  If neither a file nor	a file system is specified, statistics
	  for all mounted file systems are displayed.

	  When file system disk	usage exceeds 100% of the allowed
	  space	for users, the df command displays a negative number
	  of free blocks. The allowed space for	users is typically 90%
	  of disk capacity, with 10% reserved for use by root only.
	  However, system administrators may specify either less or
	  more reserved	space for use by root.

     LIMITATIONS AND WORKAROUNDS
	  For information about	limitations and	workarounds, see the
	  release notes	files in /usr/share/release_notes.
