[Request] Notification from console/commandline

Is there a package that provides a console/commandline utililty for generating a notification?

When I plug in my iPhone to my linux machine, the linux machine spawns a number of tasks to connect iproxy, ssh, etc, to the iPhone. I find that sometimes usbmuxd is locked up and needs a restart for these tasks to work properly.

It'd be nice to be able to generate a notification from the iOS console/commandline to indicate that these tasks were successful on the iPhone. I already have an inotify message that appears on the linux machine.
