pkill MyAppName

If your app runs under a different user account than what you use for ssh, then you can add the -u switch like so:

pkill -u username MyAppName

And you can further automate this if your local machine is a Mac or Linux box (may be possible on Windows with some utility) by running ssh with the above command:

ssh root@yourdomain.com pkill -u username MyAppName

Of course, change “root” to whatever account you use to connect with ssh. ssh will prompt for your password, then run the command and disconnect.
