Python 2.7 Run linux command and get output
This is one of the common requirement to run linux command and get output in the variable. Here is the sample code to achieve it. You need to import subprocess library for this and call the Popen method of subprocess.
Python 3.5+, subprocess library is having the support of run() method which is using to run linux command and get output.
Program:
import sys import subprocess command = "ls -lh" sys.stdout.flush() p = subprocess.Popen(command, stdout=subprocess.PIPE, shell=True) (output, err) = p.communicate() print ("output = {}".format(output)) print ("type(output) = {}".format(type(output)))
