How to kill a process in Ubuntu

1.Type Top and check all the processes running

2. If you dont' get your process name there.

Then if you know what process you kill.

Use:

(here I want to check any processes with 'jet)

ps -aef | grep mine

You would get something like this:

sony@ubuntu:~$ ps -aef | grep mine
