[ale] Expect?

[Lightner, Jeff]

Have a look at "autoexpect".  It will create an expect script for you by
recording what you do.   You should have a man page for it if you have
expect package installed.

The resulting script sometimes requires tweaking but it is better than
writing from scratch.

Also "kill -9" should be a last resort - it tells programs not to clean
up after themselves so can leave memory hooks, open files, open shared
memory segments etc... that can either impact performance over time or
completely prevent things from starting because the memory address they
want isn't available or there isn't a big enough contiguous chunk of
memory to create the shared memory segment.

Try doing a progressive kill (e.g.  kill <PID>, use ps to see if it went
away, if not kill -1 <PID>, check with ps again and finally "kill -9
<PID>" if that didn't kill it.

Yes.  I've worked with Expect the scripting language and the Perl
module.  Works very well.
