 NAME    [Toc]    [Back]
      bdf - report number of free disk blocks (Berkeley version)

 SYNOPSIS    [Toc]    [Back]
      /usr/bin/bdf [-b] [-i] [-l] [-s] [-t type | [filesystem|file] ... ]

 DESCRIPTION    [Toc]    [Back]
      The bdf command displays the amount of free disk space available
      either on the specified filesystem (/dev/dsk/c0d0s0, for example) or
      on the file system in which the specified file (such as $HOME), is
      contained.  If no file system is specified, the free space on all of
      the normally mounted file systems is printed.  The reported numbers
      are in kilobytes.

    Options    [Toc]    [Back]
      The bdf command recognizes the following options:

           -b             Display information regarding file system
                          swapping.

           -i             Report the number of used and free inodes.

           -l             Display information for local file systems only
                          (for example, HFS and CDFS file systems).

           -s             Do not sync the file system data on the disk
                          before reporting the usage.

           -t type        Report on the file systems of a given type (for
                          example, nfs or hfs).

 RETURN VALUE    [Toc]    [Back]
      The bdf command returns 0 on success (able to get status on all file
      systems), or returns 1 on failure (unable to get status on one or more
      file systems).

 WARNINGS    [Toc]    [Back]
      If file system names are too long, the output for a given entry is
      displayed on two lines.

      The bdf command does not account for any disk space reserved for swap
      space, or used for the HFS boot block (8 KB, 1 per file system), HFS
      superblocks (8 KB each, 1 per disk cylinder), HFS cylinder group
      blocks (1 KB - 8 KB each, 1 per cylinder group), and inodes (currently
      128 bytes reserved for each inode).  Non-HFS file systems may have
      other items not accounted for by this command.
