DF(C)                    XENIX System V                     DF(C)



     Name
          df - Report number of free disk blocks.

     Syntax
          df [ -t ] [ -f ] [ -v -i ] [ file-systems ]

     Description
          df prints out the number of free blocks and free inodes
          available for on-line file systems by examining the counts
          kept in the super-blocks; file-systems may be specified by
          device name (e.g., /dev/root).  If the file-systems argument
          is unspecified, the free space on all of the mounted file
          systems is sent to the standard output.  The list of mounted
          file systems is given in /etc/mnttab.

          Options include:

          -t   Causes total allocated block figures to be reported as
               well as number of free blocks.

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

          -v   Reports the percent of blocks used as well as the
               number of blocks used and free.

          -i   Reports the percent of inodes used as well as the
               number of inodes used and free.  Use the -i option with
               the -v option to display counts of blocks and inodes
               free as well as the percentage of inodes and blocks
               used.

          The -v and -i options can not be used with other df options.

          This utility reports sizes in 512 byte blocks.  On systems
          which use 1024 byte blocks, this means a file of 500 bytes
          uses 2 blocks. df will report 2 blocks less free space,
          rather than 1 block, since the file uses one system block of
          1024 bytes.  Refer to the machine(HW) manual page for the
          block size used by your system.
