Question

My python script needs to start a background process and then continue processing to completion without waiting for a return.

The background script will process for some time and will not generate any screen output.

There is no inter-process data required.

I have tried using various methods subprocess, multiprocessing but am clearly missing something.

Does anyone have a simple example?

TIA

Answer 1

how about this:

import subprocess
from multiprocessing import Process

Process(target=subprocess.call, args=(('ls', '-l', ), )).start()

It’s not all that elegant, but it fulfils all your requirements.
