 NAME
      df - report number of free CDFS, HFS, or NFS file system disk blocks

 SYNOPSIS
      /usr/bin/df [-F FStype] [-befgiklntv] [-B] [-o specific_options] [-V]
	   [special|directory]...

 DESCRIPTION
      The df command displays 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 mounted file systems is displayed.
      If the arguments to df are path names, df reports on the file systems
      containing the named files.  If the argument to df is a special of an
      unmounted file system, the free space in the unmounted file system is
      displayed.

    Options
      df recognizes the following options:

	   -b		  Report only the number of kilobytes (KB) free.

	   -B		  Report the total number of blocks allocated for
			  swapping to the file system as well as the number
			  of blocks free for swapping to the file system.
			  This option is supported on HFS file systems only.

	   -e		  Report the number of files free.

	   -f		  Report only the 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 FStype	  Report only on the FStype file system type (see
			  fstyp(1M)).  For the purposes of this manual
			  entry, FStype can be one of cdfs, hfs, and nfs,
			  for the CDFS, HFS, and NFS file systems,
			  respectively.

	   -g		  Report the entire structure described in
			  statvfs(2).

	   -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 (KB).

	   -l		  Report on local file systems only.

	   -n		  Report the file system name.	If used with no
			  other options, display a list of mounted file
			  system types.

	   -o specific_options
			  Specify options specific to the HFS file system
			  type.	 specific_options is a comma-separated list
			  of suboptions.

			  The available suboption is:

			       i    Report the number of used and free
				    inodes.

	   -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 perform 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.

      When df is used on an HFS file system, the file space reported is the
      space available to the ordinary user, and does not include the
      reserved file space specified by fs_minfree.

      Unreported reserved blocks are available only to users who have
      appropriate privileges.  See fs(4) for information about fs_minfree.

      When df is used on NFS file systems, the number of inodes is displayed
      as -1 .  This is due to superuser access restrictions over NFS.

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

	   df

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

	   df -F hfs

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

	   df -F nfs -e

 df_hfs(1M)							  df_hfs(1M)




      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:

	   df -t /usr

 WARNINGS
      df does not account for:

	   +  Disk space reserved for swap space,
	   +  Space used for the HFS boot block (8K bytes, 1 per file
	      system),
	   +  HFS superblocks (8K bytes each, 1 per disk cylinder),
	   +  HFS cylinder group blocks (1K-8K bytes each, 1 per cylinder
	      group),
	   +  Inodes (currently 128 bytes reserved for each inode).

      Non-HFS file systems may have other items that this command does not
      account for.

      The -b option, from prior releases, has been replaced by the -B
      option.

 FILES
      /dev/dsk/*	  File system devices.
      /etc/fstab	  Static information about the file systems
      /etc/mnttab	  Mounted file system table
