I am a new Linux system user. How do I kill a process on Linux based server using command line options? How can I kill running process on Unix?

First check the pid of target process. for example, we want to kill firefox process then run below command

pidof firefox

now on output you will see process IDs/ID. next run a command to kill this process

kill -9  type_here_pid_of_firefox

done
