kill doesn't kill

[callkalpa]

I'm using Fedora 10.
I have a process of avidemux2_qt4 (a video editing tool) and I want to kill it.

I tried with

kill

kill -9

kill -15

each one with/without sudo

still the process is there. How can I kill this process ?

Have you tried killing the parent process? In UNIX, if you kill the parent process of some other process, all of the parent's child processes will die with it. You can check what the parent process is by running:

ps -ef | grep avidemux2_qt4 | grep -v grep | awk '{print $3}' | xargs ps -p

If the parent process is init or /sbin/init (parent process ID of 1), do not kill it or even try. The kernel probably won't let you but your system will halt if you manage to do it successfully. That also means that the process has probably become a zombie because init will automatically reclaim zombied processes.

If you still can't kill it, what about rebooting your computer? That's the only guaranteed way to do it.

I didn't try to kill the parent process.
I reboot the PC. so that there are no such processes now. So I can't check with the command you have provided. Thanks for the command.

In case of a same situation I'll try this and will let you know the result.
