This was a funny post that only my nerd friends are even going to understand. Sorry you poor people on windows. None of this will work.
This was found here. http://www.tecmint.com/20-funny-commands-of-linux-or-linux-is-fun-in-terminal/
I will just list a few
Command: sl (Steam Locomotive)
You might be aware of command ‘ls‘ the list command and use it frequently to view the contents of a folder but because of miss-typing sometimes you would result in ‘sl‘, how about getting a little fun in terminal and not “command not found“.
Install sl
root@tecmint:~# apt-get install sl (In Debian like OS)
root@tecmint:~# yum -y install sl (In Red Hat like OS)
Output
root@tecmint:~# sl
sl command
This command works even when you type ‘LS‘ and not ‘ls‘.
Command: rev (Reverse)
It reverse every string given to it, is not it funny.
root@tecmint:~# rev
123abc
cba321
xuniL eb ot nrob
born to be Linux
Command: Cowsay
An ASCII cow in terminal that will say what ever you want.
Install Cowsay
root@tecmint:~# apt-get install cowsay (for Debian based OS)
root@tecmint:~# yum install cowsay (for Red Hat based OS)
Output
root@tecmint:~# cowsay I Love nix
____________
< I Love nix >

How about pipelineing ‘fortune command‘, described above with cowsay?
root@tecmint:~# fortune | cowsay

Note: ‘|‘ is called pipeline instruction and it is used where the output of one command needs to be the input of another command. In the above example the output of ‘fortune‘ command acts as an input of ‘cowsay‘ command. This pipeline instruction is frequently used in scripting and programming.
