How to kill specific java process?

Question

ps -aux | less displays

java -jar /var/appname.jar

Now I'm killing it by

killall -9 java

But if there is also another java process java -jar /var/anotherappname.jar how to kill only the first one?

Answer 1

I'd suggest using pkill, with the -f flag to match against the whole command:

pkill -f /var/appname.jar

Test first with

pgrep -af /var/appname.jar

From man pkill:

   -f, --full
          The pattern is normally only matched against the  process  name.
          When -f is set, the full command line is used.
