TCOPY(1) BSD Reference Manual TCOPY(1)
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 (rmt0 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.
-c Copy src to dest and then verify that the two tapes are identi-
Specify a maximum block size, maxblk.
-v Given the two tapes, and dest verify that they are identical.
-x Output all informational messages to the standard error. This
option is useful when dest is /dev/stdout.
The tcopy command appeared in 4.3BSD.
