Hello Linux Geeksters.

In this article I will show you some Ubuntu / Linux / Unix Easter Eggs. No, I do not refer to the coloured eggs we smash on Easter, but some terminal entertainment.
1. SL:
sl stands for Steam Locomotive.
When you type sl, accidentally instead of ls, you get a Locomotive, if you install the sl package:
$ sudo apt-get install sl
$ sl
2. Moo:
You sure know moo, don’t you?
$ sudo apt-get moo
3. If you like the cow thingy, do this: Cowsay.
$ sudo apt-get install cowsay fortune-mod
$ fortune | cowsay
Output:
4. Aptitude moo:
