Correct your habit of incorrectly typing "ls" using the program "sl"

Almost everyone of us would have made the mistake of incorrectly typing “sl” or “LS” instead of a simple “ls”. Seriously! how difficult could it be to type those two letters? But we keep making the same mistake over and over. In order to correct this problem, there is a wonderful program name “sl”. It shows a small animation of a steam locomotive(abbr. sl) every time we type “sl” or “LS”. It may sound funny as of now, but trust me, its really annoying when you are doing some serious work and suddenly a locomotive comes out of nowhere, running across the terminal.

The  annoying part is that it doesn't respond to Ctrl-C and there is nothing one can do in such a short time other than viewing it get past. Now that I'm thinking, it'd be fun to pull a prank on someone who isn't aware of sl.

Here is how you install the package.

[shredder12]$ sudo apt-get install sl

Well, its annoying nature does makes it work. Sooner or later you stop making the mistakes. Here are two different versions of the locomotive.

[shredder12]$ sl -a

[shredder12]$ sl -l
