for example from bash:
kill -9 -PID
os.kill(pid, signal.SIGKILL) kill only parent process.

A process can be killed by calling the Process. kill() function. The call will only terminate the target process, not child processes.
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.
We can kill or terminate a process immediately by using the terminate() method. We will use this method to terminate the child process, which has been created with the help of function, immediately before completing its execution.
You can use ps aux | grep python to determine the running Python processes and then use kill <pid> command for sending a SIGTERM signal to the system. To kill the program by file name: pkill -f python-script-name.
you should use signal parameter 9 to kill the process tree. root@localhost:~$ python >>> import os >>> os.kill (pid, 9) if you should use signal.SIGKILL constant, you should use os.killpg (pgid, signal.SIGKILL) to kill the process tree.
If you want to kill all processes which includes in process group then you should use parent process id. Like that:
When you pass a negative PID to kill, it actually sends the signal to the process group by that (absolute) number. You do the equivalent with os.killpg () in Python. Show activity on this post. Another solution if your process is not a process group and you don't want to use psutil, is to run this shell command: Show activity on this post.
I use SIGKILL on Linux, to kill process immediatly, and SIGTERM on Windows, because there is no SIGKILL on it. Also I used killpg () to kill the whole group of processes on Linux. P.S. Check on Linux, but still doesn't check on Windows, so maybe we need one more additional command for Windows (for example CTRL_C_EVENT or use another answer .)
If the parent process is not a "process group" but you want to kill it with the children, you can use psutil (https://psutil.readthedocs.io/en/latest/#processes). os.killpg cannot identify pid of a non-process-group.
import psutil parent_pid = 30437 # my example parent = psutil.Process(parent_pid) for child in parent.children(recursive=True): # or parent.children() for recursive=False child.kill() parent.kill() If you love us?
