Command:   dosdir - list an MS-DOS directory [IBM]
Syntax:    dosdir [-lr] drive
Flags:     -l  Long listing
           -r  Recursively descend and print subdirectories
Examples:  dosdir -l A              # List root directory on drive A
           dosdir -r C x/y          # Recursively list directory x/y
           dosdir -r fd1            # List device /dev/fd1

     Dosdir reads standard IBM PC diskettes or hard disk  partitions  in
MS-DOS  format  and  lists their contents on standard output.  Directory
names should contain slashes to separate components, even though  MS-DOS
uses backslashes.  The names dosdir, dosread, and doswrite are all links
to the same program.  The program sees  which  function  to  perform  by
seeing  how  it was called.  A drive code of A causes the program to use
/dev/dosA, for example, a link to /dev/fd0.   Similarly,  to  have  hard
disk  partition 1 be DOS drive C, /dev/dosC could be a link to /dev/hd1,
and so on for other drive codes.  A normal device name may also be  used
instead of a drive code.
