.Sh DESCRIPTION
|
|
.Nm
|
|
is designed to copy magnetic tapes.
|
|
The only assumption made
|
|
about the tape is that there are two tape marks at the end.
|
|
.Nm
|
|
with only a source tape
|
|
.Pf ( Ar /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.
