You probably should consider using the Popen class in the new
subprocess module. It makes all previous mechanisms (system,
popen, commands, fork, execv etc) obsolescent.
There are basic instructions for using Popen to replace popen[n]
etc in my new OS topic on the web site and the documentation
gives some rather terse examples too...
