      NAME
           mc - cartridge tape manipulating program

      SYNTAX
           mc [ -f tapename ] command [ count ]

      DESCRIPTION
           Mc passes certain commands to a cartridge tape drive.  If
           tapename is not specified, mc sends the command to the
           cartridge tape device named by the environment variable
           CTAPE. If CTAPE does not exist, commands go to the device
           /dev/nct0.

           By default, mc performs the command once.  Count may be
           entered to perform the command multiple times.

           Only as many characters as are required to uniquely identify
           a command need be specified.  The possible commands are:

           eof, weof
                Write count end-of-file marks at the current position
                on the tape.

           fsf  Forward space count files.

           fsr  Forward space count records.

           eod  Position tape after the end of recorded data (count is
                ignored).

           retension
                Retension the cartridge tape by winding to the end and
                then rewind to the beginning.  This operation takes a
                few minutes and is recommended for all new tapes before
                they are used to record data (count is ignored).

           rewind
                Rewind the tape (count is ignored).

           status
                Print status information about the tape unit.

           Mc returns a 0 exit status when the operation(s) were
           successful, 1 if the command was unrecognized, and 2 if an
           operation failed.
