       df_hfs:	df  - report number of free CDFS, HFS, or NFS file system disk

       FStype] specific_options] [special|directory]...

       The 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	speci‐
       fied,  the free space on all mounted file systems is displayed.	If the
       arguments to are path names, reports on the file systems containing the
       named files.  If the argument to is a special of an unmounted file sys‐
       tem, the free space in the unmounted file system is displayed.

       recognizes the following options:

	      Report only the number of kilobytes (KB) free.

	      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.

	      Report the number of files free.

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

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

	      Report the entire structure described in

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

	      Report the allocation in kilobytes (KB).

	      Report on local file systems only.

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

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

			     The available suboption is:

				  Report the number of used and free inodes.

	      Report the total allocated block figures and the number of  free

	      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.

	      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 This option allows the user to ver‐
			     ify the command line.

       When 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

       Unreported reserved blocks are available only to users who have	appro‐
       priate privileges.  See tunefs(1M) for information about

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

	      ·	 HFS superblocks (8K bytes each, 1 per disk cylinder),
	      ·	 HFS  cylinder	group blocks (1K-8K bytes each, 1 per cylinder
	      ·	 Inodes (currently 128 bytes reserved for each inode).

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