Hello python devs!

Question here is to practically execute and external command like a system command, and get the output in a variable to work with.

Do do such, use subprocess import:

#!/usr/bin/env python
import subprocess
import pprint
 

cmd = "cd /opt;ls -l"

p = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)

(output, err) = p.communicate()
 
p_status = p.wait()

pprint(output)


exit()

Note the "shell=True" option:https://docs.python.org/3/library/subprocess.html

You can now work on the output itself.

Even if you are supposed to get json as output, you'll probably need to delete unwanted characters like "\n":

output = output.replace("\n", "")

  Or transform dict like ouput into real dict:   add import ast at the beginning of the file +   

dictresult = ast.literal_eval(output)

Hope it helps friends, see you!
