copy and/or verify mag tapes
tcopy is designed to copy magnetic tapes.
The only assumption made about the tape is that there are two tape marks at
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.
- 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.
