C 6 tcopy - copy and/or verify mag tapes tcopy [ -cv ] [ -s maxblk ] [src [ dest ]]

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.

The -s option allows you to specify a maximum block size. The -v option verifies that two tapes are identical. The -c option does the copy and then verifies that the two tapes are identical.
