DF(1)                   COMMAND REFERENCE                   DF(1)



NAME
     df - disk free

SYNOPSIS
     df [ -i ] [ filesystem...][ filename...]

DESCRIPTION
     Df prints out the amount of free disk space available on the
     specified filesystem, e.g. ``/dev/rp0a'', or on the
     filesystem in which the specified file, e.g. ``$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.

     There are two output formats.  The following columns are
     listed normally:



          Filesystem  kbytes  used  avail  capacity  Mounted on


     The Filesystem column lists the name of the device for the
     filesystem, such as /dev/hp0a. The kbytes column lists the
     number of kilobytes on the device.  The used column lists
     the number of kilobytes allocated to files.  The avail
     column lists the number of kilobytes still available for
     files.  The capacity column lists the percentage of the
     filesystem space that is allocated.  The Mounted on column
     lists the name of the root of the filesystem, such as /.

     When the -i option is given, the following columns are also
     given:



          iused   ifree  %iused


     The iused column lists the number of inodes allocated.  The
     ifree column lists the number of inodes still available.
     The %iused column lists the percentage of the total number
     of inodes that are allocated.

OPTIONS
     -i  Causes df to also report the number of inodes used and
         free.

EXAMPLES
     The following example prints a report of the free and used
     disk space and inodes in the file system /tmp.

          df -i /tmp


FILES
     /etc/fstab               File containing the list of
                              normally mounted filesystems.

     /etc/mtab                File containing the mounted
                              filesystem table.

RETURN VALUE
     [NO_ERRS]      Command completed without error.

     [USAGE]        Incorrect command line syntax. Execution
                    terminated.

     [NP_WARN]      An error warranting a warning message
                    occurred. Execution continues.

     [P_WARN]       A system error occurred. Execution continues.
                    See intro(2) for more information on system
                    errors.

     [P_ERR]        A system error occurred. Execution
                    terminated.  See intro(2) for more
                    information on system errors.

CAVEATS
     The capacity of a file system can be reported as more than
     100% because swap space may be being used.  The swap space
     is not normally included in the statistics.
