There's nothing wrong with using os.popen. Some of them are Unix specific though. And that module's functionality along with os.system, os.spawn and commands have all be integrated into the subprocess module, which I think is much less confusing. The only places I've seen a fairly coherent run-down of the os.popen modules is the "Python in a Nutshell" book and maybe (I can't remember for sure) "Core Python Programming". See http://pydoc.org/2.4.1/subprocess.html for more info on the subprocess module. Mike -- http://mail.python.org/mailman/listinfo/python-list
