How to safely close Intellij from command line?

I'm using Intellij on my Rhel machine. I often use remote login to work from home. But since Intellij allows only one instance at a time, it needs to be killed to start a new instance remotely. However, this is not a clean close & many times I end up losing some recent changes. So, my question is - Is there a way to cleanly kill the currently running Intellij from command line?
