Kill Process by name?

[RobinVossen]

I need a button that destorys all the VNC sessions on the box.
And thus logs the Entire system off nicely..
Is there a way to do this nicely?
Like:

ps aux

or

ps -C vnc

and then add some Kill Function behind it?

Already thanks a lot =)

Cheers,
Robin

You can just use the killall command. This will look up all PIDs by app name and kill them off.

heh thanks but it aint that easy
Since there are some Deamons running that NEVER may stop..
So, killall aint a option..

My 'stop' script still serves a good purpose. It searches for patterns, not just names of processes. So you can kill by user, or any other pattern in the output of <ps aux>. Note! That it's buggy as hell and that it has caused discussing wetter or not it should work in theoretical terms. I keep it as a last resort.

#!/bin/bash
# Stop v0.03

if [ ! $1 ] ; then
        echo "Stop what?"
else
        for i in `ps aux | grep -i $1 | grep -v grep | awk '{print $2}' ` ; do
        kill -9 $i
done
exit 0
fi

EDIT: Oh! I thought you said VLC. To kill it if it's not responding. I wouldn't know how a system responds when all VNC sessions receive the kill -9 signal. But it wont end nicely.

Yes it will this is great =)
Since if all the VNC close I wont have problems with VNC on Display 2 and stuff ^^

Thanks

I did Deploy it now, and it works WONDERFULL!! =)
Thanks a lot... but.. for some reason my PC cant count anymore..
It starts the vnc server now on xvnc:2 instead of 1..
Weird stuff.. And when I try to start with vncserver:1 I get the value returned 127..
