Start the Android media scanner from the command line

If you're like me, and let's hope for your sake that you're not, you find it much easier to run an SSH server on your Android device than using something like adb or USB Mass Storage or any of the other crap out there.

With SSH I can simply and easily check logcat, netstat, issue commands, copy files and generally bugger about.

Sometimes you have moved quite a lot of files around and you need your media scanner to launch to update its database. This can be done via the CLI.
