+.Sh NAME
+.Nm tcopy
+.Nd copy and/or verify mag tapes
+.Sh SYNOPSIS
+.Nm tcopy
+.Op Fl cvx
+.Op Fl s Ar maxblk
+.Oo Ar src Op Ar dest
+.Oc
+.Sh DESCRIPTION
+.Nm Tcopy
+is designed to copy magnetic tapes.  The only assumption made
+about the tape is that there are two tape marks at the end.
+.Nm Tcopy
+with only a source tape
+.Pf ( Ar 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.
+.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
+Specify a maximum block size,
+.Ar maxblk .
+.It Fl v
+Given the two tapes,
+.ar src
+and
+.Ar dest
+verify that they are identical.
+.It Fl x
+Output all informational messages to the standard error.
+This option is useful when
+.Ar dest
+is
+.Pa /dev/stdout .
+.El
+.Sh SEE ALSO
+.Xr mtio 4
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.3 .
