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


       prints  the  number of free blocks and free inodes in VxFS file systems
       or directories based on the counts kept in the super-blocks.

       VxFS dynamically allocates inodes from a pool of free blocks.  The num‐
       ber  of	free inodes and blocks reported by is an estimate based on the
       number of free 8K or larger extents and the current ratio of  allocated
       inodes to allocated blocks.  (Extents smaller than 8K may not be usable
       for all types of allocation, so does not count free blocks  in  extents
       smaller	than 8K.)  Allocating additional blocks may therefore decrease
       the count of free inodes and vice versa.

       If the operand to is a special device name, the file system can	be  an
       unmounted  or mounted file system (for example, If you specify a direc‐
       toryname, displays information for the file system at that mount point.
       If neither special nor directory is specified, the free space on all of
       the mounted file systems is printed.

       recognizes the following options:

	      Report only the number of kilobytes free.

	      Report the number of files free.

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

	      Specify the file system type

	      Report the entire
			     statvfs(2) structure.

	      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.

	      Report on local file systems only.

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

	      Print the number of free extents of each size.
			     Free extents are always an integral power of  two
			     in length, ranging from a minimum of one block to
			     the maximum extent size  supported	 by  the  file

	      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 performs 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.

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

       recognizes the following operands:

	      directory	     Name  of the mount point from which the VxFS file
			     system is accessed.

	      special	     Device  name,  which  contains   a	  mounted   or
			     unmounted VxFS file system.

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

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

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

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

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

       File-system devices.
       File-system devices.
       Static information about the file systems.
