How could I know the PID of those childs from any other ruby interpreter? This is, I just know the PID of the parent (1000). Of course I could do some hack as inspecting the output of "ps" and inspecting the pid/ppid, but I'd prfer a ppure Ruby method for this. Thanks for any suggestion. -- Iñaki Baz Castillo
