I would take a look at expect.

It is intended for that sort of scripted
response to a prompt etc. Expect should be
able to tell ufsdump the tape is ready however
it expects to be told.

You will need tcl to use it AFAIK. I would
expect you could find it at sunsite.

The best way to do this is to decide which file systems go
with each tape. Hopefully you don't have any file systems that are
larger than 8Gig otherwise your only option is to use a product that
understands jukeboxes like Legato or Bud tool or Amanda or something
like that. If your filesystems are small enough to get 1 or more per
tape then all you need is to create a script that does a ufsdump of
each filesystem with a mt /dev/rmt/0 rewoffl (or whatever device it is)
between each ufsdump. The rewoffl will rewind the tape, eject it
and the juke should automatically load the next tape.

|I'm using Solaris 2.5 and an 8mm Exabyte jukebox.

See the l option in "man ufsdump".
