                                                DU [DUAL MODE]
     
     NAME DU - Show disk usage.
     
     SYNTAX
     
     DU [Drive(s)]  [Files(s)]  [/NOD|/S]  [+A|+R|+S|+H|+D|+A]
     [/H | /?]
     
     
     USAGE
     
     DU shows  how many  bytes each  specified file takes, its
     attributes, how much the files in the same directory take
     and  finally  how  much  all  the  specified  files  take
     together. The  amount shown is the actual number of bytes
     written  to  the  file.  Since  OS/2  reserves  space  in
     multiple of  block size,  the amount  the files take from
     the total amount of free space is bigger.
     
     DU can  be given  a list of drives e.g C: D:. DU searches
     these drives  for the  given files.  Each drive specifier
     can contain  also a directory specifier e.g c:\test, then
     DU searches starting from the test directory. Normally DU
     starts its search from the default directory.
     
     Normally DU  finds files with attribute bit, readonly bit
     or no  bits set.  You can  disable the default attributes
     with the /NOD (=No Default) switch.
     
     Files are  specified using normal OS/2 rules with ? and *
     acting as wild cards.
     
     There is  a /TEST-switch,  which is  not too sensible for
     DU.
     
     With the /S -option DU shows also all subdirectories.
     
     The following options are recongnized:
     
     
     +H include also hidden files.
     +S include system files
     +R include read-only files
     +A include files with attribute-bit.
     +D include directories (does not make too much sense with
     SCAN).
     +N include  normal files.  This is  the  default.  Normal
     files include  files with read-only or archive or no bits
     at all set.
     /NOD No  Default. Do  not include  any files  by default.
     SOme combination of attributes must be given.
     /TEST Show no files.
     /S = Include subdirectories also.
