that's an old thread, and Python has grown a few more ways to
deal with shell commands since then.  if os.system isn't good en-
ough for you, subprocess is the preferred alternative:

(also note that most trivial shell commands are better done in
python.  most uses of cat, for example, can be trivially emulated
with one or two lines of python...)
