utility is designed to copy magnetic tapes. The only assumption made about the tape layout is that there are two sequential EOF marks at the end. By default, the
utility will print information about the sizes of records and files found on the
tape, or on the tape specified by the
argument. If a destination tape is also specified by the
argument, a copy of the source tape will be made. The blocking on the destination tape will be identical to that used on the source tape. Copying a tape will yield the same program output as if just printing the sizes.
The following options are available:
dest and then verify that the two tapes are identical.
Specify a maximum block size,
Given the two tapes
dest, verify that they are identical.
Output all informational messages to the standard error instead of the standard output. This option is useful when
dest is given as
