if there are multiple java processes and you wish to kill them with one command try the below command

kill -9 $(ps -ef | pgrep -f "java")

replace "java" with any process string identifier , to kill anything else.

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  lt MainClass gt    awk   print  1      MainClass is a class in your running java program which contains the main method

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

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

pkill -f for whatever reason does not work for me  Whatever that does  it seems very finicky about actually grepping through what ps aux shows me clearly is there   After an afternoon of swearing I went for putting the following in my start script     ps aux   grep -v -e  grep     grep MainApp   tr -s       cut -d     -f 2   xargs kill -9      true
