TCOPY(1)                     BSD Reference Manual                     TCOPY(1)

NAME
     tcopy - copy and/or verify mag tapes

SYNOPSIS
     tcopy [-cv] [-s maxblk] [src [dest]]

DESCRIPTION
     Tcopy is designed to copy magnetic tapes.  The only assumption made about
     the tape is that there are two tape marks at the end.  Tcopy with only a
     source tape (rmt0 by default) specified will print information about the
     sizes of records and tape files.  If a destination is specified a copy
     will be made of the source tape.  The blocking on the destination tape
     will be identical to that used on the source tape.  Copying a tape will
     yield the same output as if just printing the sizes.

     Options:

     -c        Copy src to dest and then verify that the two tapes are identi-
               cal.

     -s maxblk
               Specify a maximum block size, maxblk.

     -v        Given the two tapes, and dest verify that they are identical.
