Find and kill a process in one line using bash

For operation and other pusposes, we need to kill process in linux system. For this purpose, at first we find the process id then we kill the process with the process id. i.e

[agentrpt@localhost ~]$ ps -ef | grep 'jar'
agentrpt 13131     1  0 16:49 ?        00:00:00 java -jar ABS_ALERT_MIDDLEWARE.jar
agentrpt 13278     1  0 16:54 ?        00:00:00 java -jar SMSMailClient.jar
agentrpt 13402 13367  0 16:58 pts/0    00:00:00 grep jar

For killing process of java -jar SMSMailClient.jar, We need to executge command as:
kill 13278

We can do it in a simple way. For the using the script regulary we can create a script with the below command.

In bash, you should be able to do:

kill $(ps aux | grep '[SMS]MailClient.jar' | awk '{print $2}')

Details on its workings are as follows:

The ps gives you the list of all the processes.
The grep filters that based on your search string, [SMS] is a trick to stop you picking up the actual grep process itself.
The awk just gives you the second field of each line, which is the PID.
