I have two shell programs - one that launches the other in the

normal circumstances) will shut down gracefully.
However, if things don't work fine, the background process sticks around
to plague me later.
I'd like to end my main script by killing the background process (if
it's still around), but I'm having a helluva time figuring out HOW.
I can use "kill $!" in the main script, but that only kills the
background bash process, leaving the utility program running.
Questions:
1) Is "kill %?name" supposed to work in this environment?
2) Is there a simple way to kill a process along with its children?
'kill -SIGHUP <process>'? Or if the child is a bash script, you might be
able to re-write it to trap a signal (e.g. SIGUSR1) that instructs the
child to kill /its/ child (the assumption being that the child knows its
own child's PID).
