- copy a magnetic tape
tcopy source [destination]
The tcopy utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the contents of a tape is that there are two tape marks at the end.
When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a destination is specified, tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy produces the same output as it does when only scanning a tape.
The tcopy utility requires the use of Berkeley-compatible device names. For example,
example% tcopy /dev/rmt/1b /dev/rmt/2b
