kill itself

mauler123 · #1 (**permalink**) 03-30-2009

Hey I need to write a script that can kill itself. I have to use the command kill within it.

So I have gotten my head around to that I need to use ps to get the PID but I have no idea how to store that PID in a variable to be able to then kill the script.

So is there a way to grab the PID within the script so that I can kill it?

Surely "exit" is easier.
The PID of the current shell is
$$
e.g.
PID=$$
echo "${PID}"
Be careful. It is rarely necessary to kill processes which are under control.

Except I have to use the kill command. One of those pesky requirements.

EDIT: Sorry I didn't see your explanation at first. Thanks a bunch that was giving me a somewhat hard time. I'm fairly new to unix in general and really do not spend that much time with it.
