NAME
tcopy
- copy and/or verify mag tapes
SYNOPSIS
tcopy
[-cvx]
[-s maxblk]
[src[ dest]]
DESCRIPTION
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.
Options:
- -c
-
Copy
src
to
dest
and then verify that the two tapes are identical.
- -s maxblk
-
Specify a maximum block size,
maxblk.
- -v
-
Given the two tapes,
src
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
.
