hpux 10.20 - df (1)

 NAME
      df (generic) - report number of free file system disk blocks

 SYNOPSIS
      /usr/bin/df [-F FStype] [-befgiklnv] [-t|-P] [-o specific_options] [-V]
           [special|directory]...

 DESCRIPTION
      The df 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
      specified, the free space on all mounted file systems is displayed.
      If the arguments to df are path names, df reports on the file systems
      containing the named files.  If the argument to df is a special of an
      unmounted file system, the free space in the unmounted file system is
      displayed.

    Options
      df recognizes the following options:

           -b             Report only the number of kilobytes (KB) free.

           -e             Report the number of files free.

           -f             Report only the actual count of the blocks in the
                          free list (free inodes are not reported).

           -F FStype      Report only on the FStype file system type (see
                          fstyp(1M)).

           -g             Report the entire structure described in
                          statvfs(2).

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

           -k             Report the allocation in kilobytes (KB).

           -l             Report on local file systems only.

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

           -o specific_options
                          Specify options specific to each file system type.
                          specific_options is a comma-separated list of
                          suboptions intended for a specific FStype module
                          of the command.  See the file-system-specific
                          manual entries for further details.

           -P             Report the name of the file system, the size of
                          the file system, the number of blocks used, the
                          number of blocks free, the percentage of blocks
                          used and the directory below which the file system
                          hierarchy appears.

           -t             Report the total allocated block figures and the
                          number of free blocks.

           -v             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.

           -V             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 /etc/fstab.  This option
                          allows the user to verify the command line.

 EXTERNAL INFLUENCES
    Environment Variables
      LC_MESSAGES determines the language in which messages are displayed.

      If LC_MESSAGES is not specified in the environment or is set to the
      empty string, the value of LANG is used as a default for each
      unspecified or empty variable.  If LANG is not specified or is set to
      the empty string, a default of "C" (see lang(5)) is used instead of
      LANG.

      If any internationalization variable contains an invalid setting, df
      behaves as if all internationalization variables are set to "C".  See
      environ(5).

    International Code Set Support
      Single-byte and multi-byte character code sets are supported.
