Problem with module "subproccess" in Kali-Linux Python3

Question

I have this code:

import subprocess as sp
sp.call("echo 1 > /proc/sys/net/ipv4/ip_forward")

after execution I have next problem:
raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'echo 1 > /proc/sys/net/ipv4/ip_forward' .

BUT if I call this command in cmd line it works! I want this to work in the python script. Please help!

Answer 1

Since its just one string you pass to the function, add the parameter: shell=True.

# like
sp.call("echo 1 > /proc....", shell=True)

Answer 7

Niiice, no problem at all! Oh, and Андрей Пермяков , a warning. Keep that code to yourself. Using the shell=True parameter allows for arbiturary code to be ran in your shell wich has big potential damage to your system. (as long as it's just you, you'll be fine) Just be careful who you let around this one and I wouldn't delete anything, it WILL work haha
