Hi I am developing a application in linux for which I am writing a shell script to run ffmpeg and it was working fine but when i want to kill the process of ffmpeg it was not working
kill 2628
where 2628 is my process id
you can use pkill command to force kill the process it will definitely kill the process just try it

When I want to kill a process using the pid in linux, its subprocess still existes. I hope to kill all process using one command.
Suggesting command pkill -p PID pattern .
See more documentation here.
Check out process groups:
https://en.wikipedia.org/wiki/Process_group
Assuming you want to do this from a shell?
If you do a kill and make the top process negative it does a killpg under the covers and sends the signal to all the processes in the group.
I wanna stop Node server on linux but when I try to stop it, It automatically starts with new PID how can I stop this completely. Here you can see I tried to stop Nginx and Node.
How can I check if it is a linux zombie process? If yes then How can I kill it? otherwise
I have tried tried these commands.
kill pid
Kill -9 pid
killall node <<command not working
This was spawn by it's parent process, I search out parent process after killing that this stop as well.
So how can I close the terminal where the process is in with killall.
I have tried this:
In 1st terminal:
killall node
In 2nd terminal:
Ready
Terminated
But I want only the 2nd terminal to close after the node is killed.
You can use the -t option:
killall -t $(tty)
will call all processes started from the terminal session (even with nohup), including the shell. So, your terminal will get closed.
You need to also kill the process which runs the terminal, which is usually the parent process of the node process.
The question How do I get the parent process ID of a given child process? is a good place to start. You can find the PIDs of the node processes via How to find the Process ID of a running terminal program.
I run a shell script inside php (using shell_exec). I want to kill it and all processes it created when it is in operation. I know the shell script pid. Do you have any suggestion?
I am using ubuntu, php as apache module.
Thank you.
Example:
#!/bin/bash
echo hello
sleep 20
When I kill my script (shell_exec("sudo kill -9 $pid")), the sleep process is not killed which is not desired.
use
pkill -TERM -P pid
will kill the child processes
see this answer
Use this kill command instead:
kill -- -$pid
to kill the running script and all its spawned children.
I run a few processes that I created myself on my Ubuntu Server, and to kill them I run:
sudo fuser -n tcp PORT
kill -9 PID-DISPLAYED
Is there any way I can obtain the PID from a port using a shell script, then kill it by running the shell script.
Thanks.
fuser can kill it:
-k, --kill
Kill processes accessing the file. Unless changed
with -SIGNAL, SIGKILL is sent. An fuser process
never kills itself, but may kill other fuser processes.
The effective user ID of the process executing fuser is
set to its real user ID before attempting to kill.
Try using either killall, or pkill, either of which will close all processes of the type of argument you describe, for example:
killall firefox
Will kill all running instances of firefox.
See
this link of pkill.
