That sounds like an abuse of SIGHUP*. SIGHUP is supposed to be sent by the OS when the controlling terminal disconnects (as would happen when someone on a modem Hangs UP). What you are describing is more suited to SIGTERM** which is sent to processes to politely tell them to stop when possible (as in TERMinate). * http://en.wikipedia.org/wiki/SIGHUP ** http://en.wikipedia.org/wiki/SIGTERM -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
