TCOPY(1)                    General Commands Manual                   TCOPY(1)

NAME
     tcopy - copy and/or verify mag tapes

SYNOPSIS
     tcopy [-cvx] [-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 (/dev/rst0 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
               identical.

     -s maxblk
               Specify a maximum block size, maxblk.

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

     -x        Output all informational messages to the standard error.  This
               option is useful when dest is /dev/stdout.
