The only assumption made 51about the tape is that there are two tape marks at the end. 52.Nm 53with only a source tape 54.Pf ( Ar /dev/rst0 55by default) specified will print 56information about the sizes of records and tape files. If a destination 57is specified a copy will be made of the source tape. The blocking on the 58destination tape will be identical to that used on the source tape. Copying 59a tape will yield the same output as if just printing the sizes. 60.Pp 61Options: 62.Bl -tag -width s_maxblk 63.It Fl c 64Copy 65.Ar src 66to 67.Ar dest 68and then verify that the two tapes are identical. 69.It Fl s Ar maxblk 70Specify a maximum block size, 71.Ar maxblk . 72.It Fl v 73Given the two tapes, 74.ar src 75and 76.Ar dest 77verify that they are identical. 78.It Fl x 79Output all informational messages to the standard error. 80This option is useful when 81.Ar dest 82is 83.Pa /dev/stdout . 84.El 85.Sh SEE ALSO 86.Xr mtio 4 87.Sh HISTORY 88The 89.Nm 90command appeared in 91.Bx 4.3 . 92
