Guide: Baby steps - Python

Run the code in chapters/compute/processes/guides/create-process/support/popen.py. It simply spawns a new process running the ls command using subprocess.Popen(). Do not worry about the huge list of arguments that Popen() takes. They are used for inter-process-communication. You’ll learn more about this in the [Application Interaction chapter].

Note that this usage of Popen() is not entirely correct. You’ll discover why later, but for now focus on simply understanding how to use Popen() on its own.

Now change the command to anything you want. Also give it some arguments. From the outside, it’s as if you were running these commands from the terminal.
