linux script to kill java process

Question

I want linux script to kill java program running on console.

Following is the process running as jar.

[rapp@s1-dlap0 ~]$ ps -ef |grep java rapp    9473    1  0 15:03 pts/1    00:00:15 java -jar wskInterface-0.0.1-SNAPSHOT-jar-with-dependencies.jar rapp   10177  8995  0 16:00 pts/1    00:00:00 grep java [rapp@s1-dlap0 ~]$ 

Answer 1

You can simply use pkill -f like this:

pkill -f 'java -jar' 

EDIT: To kill a particular java process running your specific jar use this regex based pkill command:

pkill -f 'java.*lnwskInterface' 

Answer 2

If you just want to kill any/all java processes, then all you need is;

killall java 

If, however, you want to kill the wskInterface process in particular, then you're most of the way there, you just need to strip out the process id;

PID=`ps -ef | grep wskInterface | awk '{ print $2 }'` kill -9 $PID 

Should do it, there is probably an easier way though...
