        List Disk Usage Statistics

Usage:  du [-acdxvh-] [ disk1 disk2 ... ] 

   du prints statistics showing the total, used and free space on
   each disk partition.  If no disk partitions are specified, du
   looks for a DRIVEMASK environmental variable that can be used
   to mask off just the drives you want reported.  The DRIVEMASK
   is specified as a list of drive letters; ranges are allowed.
   Otherwise, all partitions beginning with c: are reported.
   The current disk's statistics are highlighted.  Sizes are
   normally reported in binary (1000*1024) megabytes.


   -a    If no disks are specified, report on all disks.
   -c    If no disks are specified, report on just the current disk.
   -d    Report in decimal (1,000,000) megabytes.
   -x    Report in hex (1024*1024) megabytes.
   -v    Verbose.  Give detailed cluster information.
   -h    Help.
   --    End of options.


   You may set your own choices for screen colors using these
   environmental variables:

      Name         Use                             Default
      COLORS       Normal screen colors            <null string>
      HIGHLIGHT    Current disk                    Bright

   Colors recognized are black, red, green, yellow, blue, magenta
   (or red blue), cyan (or blue green) or white.  Foreground and
   background colors may also be bright, dim or reverse.  The names
   of the colors and the words bright, dim, reverse and on may be
   in either upper or lower or mixed case.

   Either or both the foreground and background colors may be
   specified; if you don't specify a value, it's considered
   transparent and inherits the color underneath it.   HIGHLIGHT
   inherits from COLORS.  If COLORS is null, du uses the current
   screen colors it finds at startup.  Specifying COLORS=none
   turns off all use of color.
