Umm, the original poster (Tony Rhodes?) specifically asked for an HP-UX
solution. In that case, altho' /etc/ttys exists, /etc/inittab would be the
most appropriate solution since it avoids getty clones, and allows you to
automatically respawn the app. [Oracle, etc.] if it aborts. One possible
disadvantage is stty settings may not be correct if getty/login don't run
first. (I've been bit by this on HP-UX.) However, since the original poster
mentioned the need for several different Oracle apps., this could be
handled by embedding the appropriate command tail option in a script that
also runs stty (, and probably should also do something like 'trap "exit" 2
3' to prevent breaking out before Oracle starts - the inittab respawn will
then restart it). At a minimum on HP-UX, you will need to do an 'stty icrnl
ocrnl ixon'. One more point - as of HP-UX 7.0 (6.5?) if you need to do a
set[gu]id on the script, the first line MUST be '#!/bin/ksh' (or what ever
shell you want).
