df(1M)                 UNIX System V(386 Computer Only)                  df(1M)


NAME
      df (generic), dfspace - report number of free disk blocks and files/free
      disk space

SYNOPSIS
      df [-F FSType] [-befgiklntV] [current_options] [-o specific_options]
            [directory | special | resource...]
      dfspace [-F FSType]

DESCRIPTION
      The df command prints the allocation portions of the generic superblock
      for mounted or unmounted file systems, directories or mounted resources.
      directory represents a valid directory name.  If directory is specified,
      df reports on the device that contains the directory.  special represents
      a special device (e.g., /dev/dsk/0s1).  resource is an RFS/NFS resource
      name.  If arguments to df are pathnames, df produces a report on the file
      system containing the named file.

      The df command reports sizes in 512 byte blocks.  It will report 2 blocks
      less free space, rather than 1 block, since the file uses one system
      block of 1-24 bytes.

      The directory /etc/fscmd.d/TYPE contains programs for each filesystem
      type; df invokes the appropriate binary.  /etc/fscmd.d is linked to
      /etc/fs.

      current_options are options supported by the s5-specific module of df.
      Other FSTypes do not necessarily support these options.  specific_options
      indicate suboptions specified in a comma-separated list of suboptions
      and/or keyword-attribute pairs for interpretation by the FSType-specific
      module of the command.

      The generic options are:

      -F          Specify the FSType on which to operate.  This is only needed
                  if the file system is unmounted.  The FSType should be
                  specified here or are determined from /etc/vfstab by matching
                  the mount_point, special, or resource with an entry in the
                  table.

      -b          Print only the number of kilobytes free.

      -e          Print only the number of files free.

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

      -g          Print the entire statvfs structure.  Used only for mounted
                  file systems.  Can not be used with current_options or with
                  the -o option.  This option will override the -b, -e, -k, -n,
                  and -t options.

df(1M)                 UNIX System V(386 Computer Only)                  df(1M)


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

      -k          Print allocation in kilobytes. This option should be invoked
                  by itself because its output format is different from that of
                  the other options.

      -l          Report on local file systems only.  Used only for mounted
                  file systems.  Can not be used with current_options or with
                  the -o option.

      -n          Print only the FSType name.  Invoked with no arguments this
                  option prints a list of mounted file system types.  Used only
                  for mounted file systems.  Can not be used with
                  current_options or with the -o option.

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

      -V          Echo the complete command line, but do not execute the
                  command.  The command line is generated by using the options
                  and arguments provided by the user and adding to them
                  information derived from /etc/mnttab or /etc/vfstab.  This
                  option should be used to verify and validate the command
                  line.

      -o          Specify FSType-specific options.

      -v          Reports percent of blocks used as well as the number of
                  blocks used and free.  The -v option cannot be used with
                  other options.

      If no arguments or options are specified, the free space on all local and
      remotely mounted file systems is printed.

      dfspace is a shell script that uses the df command.  dfspace reports the
      available disk space for all mounted file systems with the exception of
      pseudo file systems such as /proc. dfspace reports the free disk space in
      mega bytes and also as a percentage of total disk space.

      Without arguments, dfspace reports the free disk space on all file
      systems.

      The option for dfspace is:

      -F FSType   find free disk space on FSType file system.

NOTES
      The -F option is intended for use with unmounted file systems.

      This command may not be supported for all FSTypes.

      If options -g or -n are used when there are remotely mounted resources,
      df will try to determine the remote resource's file system type. If it
      can be determined, df will print the file system type; otherwise, it will
      print unknown.
