Stop an application through terminal [closed]

Question

I am using Ubuntu and i would like to stop a running application from terminal, more precisely through a script. One way is to get the pid of the process and issue a kill command with the pid of the process. But how do i get the pid of running applications? Or is there any better way to do this?

Answer 1

you can use

ps -ax | grep application name if your searching for firefox type below command

ps -ax | grep firefox

it shows the processing id of corresponding applications you can stop that application by kill command if process id=1317,

kill -9 1317 

Answer 2

How to stop an application from opening at start?

You will have to type ps -A and Enter.

After that you will get a list of every app that that is starting by itself.

kill -9  (the number of the app)
