How to terminate JVM run from shell script?

Question

I have a shell script starting two java processes. How to ensure that when shell script process is killed, all It's children will be killed too? For example when I try to kill It, java processes remain alive:

kill -9 myscriptID

I hope myscript refers to its process-id here.

You can check for all java processes by running this:

ps -aux | grep *java*

This looks like it can help as well.

Your kill command only kills your script, not other processes that it has spawned. Best way to kill all child processes has some great answers for killing the whole tree.

That said, it seems that a better design would be to keep track of the PIDs of the child processes, and rather than sending the parent SIGKILL, send it SIGTERM (or have some other way) to trigger it to gracefully kill its children.
