How to kill when "kill" doesnt work

[Fondor]

How do i kill a process when "kill <pid>" doesnt work? Thanks in advance.

are you root?
are you just typing it in or are you using the top utility? this may be easier, just run top, spot the item you wish to terminate, press the k key and it will ask you for the pid, and it will kill it for you. You may be trying to kill something you shouldn't or you may not have sufficient permissions, in which case you will have to su to root.

Try kill -9 <process number>
as far as I know this is something like "kill it now".
Also - if you are not root, you can kill only processes created by you
(ps axu gives you info about who initiated the process)

Hope that helps

'killall app_name' is another command you could try.
