The only assumption made 23about the tape is that there are two tape marks at the end. 24.Nm Tcopy 25with only a source tape 26.Pf ( Ar rmt0 27by default) specified will print 28information about the sizes of records and tape files. If a destination 29is specified a copy will be made of the source tape. The blocking on the 30destination tape will be identical to that used on the source tape. Copying 31a tape will yield the same output as if just printing the sizes. 32.Pp 33Options: 34.Bl -tag -width s_maxblk 35.It Fl c 36Copy 37.Ar src 38to 39.Ar dest 40and then verify that the two tapes are identical. 41.It Fl s Ar maxblk 42Specify a maximum block size, 43.Ar maxblk . 44.It Fl v 45Given the two tapes, 46.ar src 47and 48.Ar dest 49verify that they are identical. 50.It Fl x 51Output all informational messages to the standard error. 52This option is useful when 53.Ar dest 54is 55.Pa /dev/stdout . 56.El 57.Sh SEE ALSO 58.Xr mtio 4 59.Sh HISTORY 60The 61.Nm 62command appeared in 63.Bx 4.3 . 64
