tcopy
copy and/or verify mag tapes

tcopy [-cvx] [-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 (/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.

The options are as follows:

Copy src to dest and then verify that the two tapes are identical.
maxblk
Specify a maximum block size, maxblk.
Given the two tapes, src and dest, verify that they are identical.
Output all informational messages to the standard error. This option is useful when dest is /dev/stdout.
