I\'m trying to port a shell script to the much more readable python version. The original shell script starts several processes (utilities, monitors, etc.) in the background
You probably want the answer to "How to call an external command in Python".
The simplest approach is to use the os.system function, e.g.:
import os
os.system("some_command &")
Basically, whatever you pass to the system function will be executed the same as if you'd passed it to the shell in a script.
