Sh NAME
Nm tcopy
Nd copy and/or verify mag tapes
Sh SYNOPSIS
Nm
Op Fl cvx
Op Fl s Ar maxblk
Oo Ar src Op Ar dest
Oc
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.
Pp
Options:
Bl -tag -width s_maxblk
It Fl c
Copy
Ar src
to
Ar dest
and then verify that the two tapes are identical.
It Fl s Ar maxblk
