Life isn't beautiful without terminal commands. There are some funny commands in Linux terminal. These commands will make us smile and keep away our stress at work.

1. sl

No, it is not ls (list) command. The command is really sl. We use the ls command on a daily basis. Many times we mistype ls to sl. We don't know about you guys but it happens lots of times with us.
Code:
sudo apt-get install sl

sl stands for Steam Locomotive. After installing we typed sl. A steam locomotive engine passes through our terminal.
