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 identi‐
	       cal.

     -s maxblk
	       Specify a maximum block size, maxblk.

     -v	       Given the two tapes, 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.
