How do I create a subprocess in Python?

Question

I would like to create a subprocess of a process.

What would be a working example which shows how to accomplish this?

Answer 1

This is what worked for me if you want to run a simple command instead of giving a seperate file

import subprocess
process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)
process.wait()
print process.returncode

To get returncode of process you can use process.returncode To get response you can use process.communicate()

in case if you are confuse you can just test this code by using command="ls"

if you are getting returncode other than 0 then you can check here what that error code means: http://tldp.org/LDP/abs/html/exitcodes.html
