    In the parent, if the fork call succeeds, $pid will contain the process ID of the child. You can then use the kill command to send any sort of signal to it (as you know the PID).
    my $pid = fork(); if ($pid == 0) { # we're the child # exec something or other } else { sleep 10; # give the child a chance kill 1, $pid; # nighty-night }
    Something along those lines will suffice.
