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 (/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: -c Copy src to dest and then verify that the two tapes are identi- cal. -s maxblk Specify a maximum block size, maxblk. -v Given the two tapes, src and dest, verify that they are identi- cal. -x Output all informational messages to the standard error. This op- tion is useful when dest is /dev/stdout.
The tcopy command appeared in 4.3BSD. MirOS BSD #10-current April 17, 1994 1
