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 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.
- 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
