Hello, I'm trying to run tar -tvf /dev/tape > /tmp/tar.out using os.spawn with the P_NOWAIT option. Howerver when I do pid = os.spawnvp(os.P_NOWAIT,'tar',('tar','-tvf','/dev/tape','>','/tmp/tar.out')) tar errors out because it gets '>' and '/dev/tape' as an argument. I need to start this in the background, and also need the process id. Any ideas? Thanks, Cipo
