i need to give super user permission to the user to write(echo) into a particular file, but when I try the following its still showing permission is denied.

any leads will be helpful.

import subprocess
import os, sys

def main():

    subprocess.run("adb shell cat /sy/bu/mm_subsys/devices/subsy/name", shell= False)
    subprocess.run(['adb shell', 'sudo'], shell =False)
    subprocess.run('adb shell "echo related > /ss/bu/mm_subsys/devices/subsy/rest_level"\n', shell= False)



if __name__ == "__main__":
    main()

    The redirection has to be done in the subshell created by `sudo`, not in the original shell. – Barmar Feb 25 '20 at 01:44
