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, 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.

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 des-
       tination  is  specified,  tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
       duces 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
