How to kill Process In Linux

Some time we fire stop command on particular process using “service” command but it doesn’t stop. In such case we need to stop the process using ps command.

Follow below steps to kill process:

Step 1 :  Before killing the process we need identify which process to kill. Use below command to find particular process:

ps -ef  | grep java

Note: Here all wunning java processes will be listed. change java to other process name as per needed.

-e : select all  running processes

-f :  list down all the process

Description: ps -ef will get all the running process list which is given to grep commnad which will only show java processes.

Step 2: Identify the process id (pid ) from above command result and use below command to kill the process:

kill pid

if above command does not work.Then use below command

kill -9 pid

-9 is special Kill signal, which will kill the process. There is very less chance of failing single with option -9.

step 3 : verify process is killed or not using step 1

Note*: use command man ps and man kill  for more options for ps and kill command.


E.g.  click to see example for find and kill tomcat process
