running a command as a super user from a python script

Question

So I\'m trying to get a process to be run as a super user from within a python script using subprocess. In the ipython shell something like

proc = subproces         


        

Answer 1

I used this for python 3.5. I did it using subprocess module.Using the password like this is very insecure.

The subprocess module takes command as a list of strings so either create a list beforehand using split() or pass the whole list later. Read the documentation for more information.

What we are doing here is echoing the password and then using pipe we pass it on to the sudo through '-S' argument.

#!/usr/bin/env python
import subprocess

sudo_password = 'mysecretpass'
command = 'apach2ctl restart'
command = command.split()

cmd1 = subprocess.Popen(['echo',sudo_password], stdout=subprocess.PIPE)
cmd2 = subprocess.Popen(['sudo','-S'] + command, stdin=cmd1.stdout, stdout=subprocess.PIPE)

output = cmd2.stdout.read().decode() 

Answer 2

Try giving the full path to apache2ctl.
