linux script to kill java process

问题:

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 ~]$

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'

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...

Use jps to list running java processes. The command returns the process id along with the main class. You can use kill command to kill the process with the returned id or use following one liner script.

kill $(jps | grep <MainClass> | awk '{print $1}') 

MainClass is a class in your running java program which contains the main method.
