NAME
     tcopy - copy a magnetic tape

SYNOPSIS
     tcopy source [destination]


DESCRIPTION
     The tcopy utility copies the magnetic tape  mounted  on  the
     tape  drive  specified  by  the  source  argument.  The only
     assumption made about the contents of a tape is  that  there
     are two tape marks at the end.


     When only a source drive is specified, tcopy scans the tape,
     and displays information about the sizes of records and tape
     files. If a destination is specified, tcopy makes  a  copies
     the  source  tape  onto  the destination tape, with blocking
     preserved. As it copies, tcopy produces the same  output  as
     it does when only scanning a tape.


     The tcopy utility requires the  use  of  Berkeley-compatible
     device names. For example,

       example% tcopy /dev/rmt/1b /dev/rmt/2b
