instead of os.system(), you want to use the subprocess module if you are using Python 2.4+: http://docs.python.org/lib/module-subprocess.html calling subprocess.Popen(["/bin/mycmd", "myarg"]) is "no wait." to save the PID: pid = subprocess.Popen(["/bin/mycmd", "myarg"]).pid if you are using Python 2.3.x and older, you have to use spawn*(): pid = os.spawnlp(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg") hope this helps! -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - "Core Python Programming", Prentice Hall, (c)2007,2001 http://corepython.com wesley.j.chun :: wescpy-at-gmail.com python training and technical consulting cyberweb.consulting : silicon valley, ca http://cyberwebconsulting.com _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
