Thanks Wesley,

 I lokked for subprocess.Popen.

os.spawnlp(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg") was to complicated for me based on the manual.


Yours sincerely,

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!
