On Windows, subprocess.Popen.terminate calls win32's TerminalProcess. However, the behavior I see is that child processes of the process I am trying to terminate are still running. Why is that? How do I ensure all child processes started by the process are killed?

For killing a child process after a given timeout, we can use the timeout command. It runs the command passed to it and kills it with the SIGTERM signal after the given timeout. In case we want to send a different signal like SIGINT to the process, we can use the –signal flag.
Many of these programs are easily executable as a command from the shell in Unix/Linux and command prompt on windows. Python provides a module named subprocess which lets us execute these programs by creating an independent child process.
By using psutil:
import psutil, os def kill_proc_tree(pid, including_parent=True): parent = psutil.Process(pid) children = parent.children(recursive=True) for child in children: child.kill() gone, still_alive = psutil.wait_procs(children, timeout=5) if including_parent: parent.kill() parent.wait(5) me = os.getpid() kill_proc_tree(me) If you love us?
