I'm horrible at shell scripting, but what I'd do in perl is:

#!/usr/bin/perl
use strict;

my $process = `ps aux | grep test`;  ## where 'test' is the name of the
process;
(my $owner, my $pid, my $junk) = split(' ',$process); # get the pid from
that process listing
my $killed = system ("kill -s HUP $pid"); #kill the process


You might want to parse the exit status of the kill command, which will
be in $killed.

I'm sure that a shell scripter (as well as a better perl coder) could
come up with a much more elegant solution...
