RPi Wheezy Fortune
Ok prepare yourself for one of the oldest pices of command line fun that comes from the days of UNIX
This will run at the commannd line prompt and is a nice little test for them thats running a putty connection before the go to a full blown VNC
sudo apt-get install fortune-mod
Once its finnished just enter fortune at the prompt (it does not like being run from root)
use your up arrow to save typing and run it again and you get another quote fom the achive theres loads.
You can use it to test script when you come to learn that, and it can be embedded in other stuff.
Basically it's a bit of fun that will kill hours if you are not carefull.
