 NAME
      df - report number of free disk blocks on a VxFS file system

 SYNOPSIS
      /usr/bin/df [-F vxfs] [-V] [-egiklnvtfb] [-o s]
	   [special | directory ...]

 DESCRIPTION
      df prints the number of free 512-byte blocks and free inodes available
      for file systems by examining the counts kept in the superblock or
      superblocks. If a special or a directory is not specified, the free
      space on all of the mounted file systems is printed.  If the arguments
      to df are pathnames, df produces a report on the file system
      containing the named file.  If the argument to df is a special, the
      file system can be an unmounted or mounted file system.

      On a Version 2 disk layout extents smaller than 8 kilobytes may not be
      usable for all types of allocation, so df does not count free blocks
      in extents below 8 kilobytes when reporting the total number of free
      blocks.

      On a Version 2 or greater disk layout, VxFS dynamically allocates
      inodes from the pool of free blocks, so the number of free inodes and
      blocks reported by df is an estimate based on the number of free
      extents and the current ratio of allocated inodes to allocated blocks.
      Allocating additional blocks may therefore decrease the count of free
      inodes, and vice versa.

    Options
      df recognizes the following options:

	   -b		  Report only the number of kilobytes free.

	   -e		  Report the number of files free.

	   -f		  Report only an actual count of the blocks in the
			  free list (free inodes are not reported).  When
			  this option is specified, df reports on raw
			  devices.

	   -F vxfs	  Specifies the file system type (vxfs).

	   -g		  Report the entire statvfs(2) structure.

	   -i		  Report the total number of inodes, the number of
			  free inodes, number of used inodes and the
			  percentage of inodes in use.

	   -k		  Report the allocation in kilobytes.

	   -l		  Report on local file systems only.

	   -n		  Report the file system name.	If invoked with no
			  other options this option prints a list of mounted
			  file system types.

	   -o s		  Print the number of free extents of each size.
			  Free extents are always an integral power of 2 in
			  length, ranging from a minimum of 1 block to the
			  maximum extent size supported by the file system.
			  (VxFS-specific option).

	   -t		  Report the total allocated block figures and the
			  number of free blocks.

	   -v		  Report the percentage of blocks used, the number
			  of blocks used and the number of blocks free. This
			  option cannot be used with other options.

	   -V		  Echo the completed command line, but performs no
			  other action.	 The command line is generated by
			  incorporating the user-specified options and other
			  information derived from /etc/fstab.	This option
			  allows the user to verify the command line.

      There are a number of options that specify output formats, some
      combinations of which are incompatible.  If an incompatible
      combination is specified, one of the options will override the
      other(s).

 EXAMPLES
      Report the number of free disk blocks for all mounted file systems:

	   df

      Report the number of free extents of each size, for all mounted VxFS
      file systems:

	   df -F vxfs -o s

      Report the number of free files for all mounted VxFS file systems:

	   df -F vxfs -e

      Report the total allocated block figures and the number of free
      blocks, for all mounted file systems:

	   df -t

      Report the total allocated block figures and the number of free
      blocks, for the file system mounted as /usr:
