Good point. That grep could be changed to
grep '[c]ommand'
or something similar that won't match itself.

Yes, hmm... I can't see any nice way to get around this with
shell hackery on $1. If the script is called with (say)
kill_foo '[^.]\<java\>'
to avoid killing javac processes, and java_vms (or whatever), and
editors editting .java files, then the grep wouldn't work on
itself, but to prevent it from working on itself in general, you
need to do some tomfoolery to restrict the class of regexps it
can take. Hmmm...
Good point.
Cheers,
Dave.
