NAME

       df - display free disk space and disk usage statistics


SYNOPSIS

       df [-k] [-t FST list ] devnum | vol | file...


DESCRIPTION

       displays  statistics  about the amount of free disk space on the speci-
       fied device number devnum (.d##), on the specified volume vol or on the
       volume  of  which file is a part.  More than one device number, volume,
       or file may be listed, and types can be mixed in the argument list.

       Values are displayed in 512-byte per block block counts.  If neither  a
       file  or  a filesystem operand is specified, statistics for all mounted
       filesystems are displayed.  Devices without valid media  (e.g.  a  3.5"
       disk drive with no disk in the drive) are not included in the output.


OPTIONS

       The following options are available:

       -k     Use  1024-byte  (1-Kbyte)  blocks rather than the default.  Note
              that this overrides the BLOCKSIZE specification from  the  envi-
              ronment.

       -t fst1,...,fstN
              Only  print  out  statistics  for  filesystems  of the specified
              types.  More than one type may be specified in a comma separated
              list.   The  list of filesystem types can be prefixed with no to
              specify the filesystem types for  which  action  should  not  be
              taken.

       For example, the df command:
            df -t nohfs,msdos
       lists all filesystems except those of type HFS and MS-DOS

       Acceptable filesystem types are as follows:

              prodos,  dos33, dos32, pascal, mfs, hfs, lisa, cpm, msdos, high-
              sierra, iso9660, appleshare.


ENVIRONMENT VARIABLES

       BLOCKSIZE
              If the environment variable BLOCKSIZE is set, the  block  counts
              will be displayed in units of that size block.


HISTORY

       df for GNO/ME was originally built-in to gsh(1).  The implementation of
       df is based on FreeBSD source code and distributed with GNO/ME v2.0.6
