 bdf(1M)                                                             bdf(1M)




 NAME
      bdf - report number of free disk blocks (Berkeley version)

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

 DESCRIPTION
      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
      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).

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

 RETURN VALUE
      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
      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.

 AUTHOR
      bdf was developed by the University of California, Berkeley.

 FILES
      /etc/fstab          Static information about the file systems.
      /etc/mnttab         Mounted file system table.
