Everyone makes mistakes while typing at the terminal, but have you ever thought to make fun out of your mistakes? sl is a program that shows a little animation in the terminal for people who type the ls command backwards. 'Hi, you are in the wrong place', this is the message this nice simple program gives to the user that wanted to list files in his directory with the ls command.
What happens when I type sl at the terminal?
Ok, the sl program is not installed but we can install it with the following command.
sudo apt-get install sl
After the program is installed, type the following command in your terminal and see what happens.
Oww guys, a train in our terminal. This is cool, isn't it? We need to do something with this train, how about an accident?
Type the following command to make an accident happen and watch people cry for help. I am kidding, this is not a real accident.
What else can we do? How about flying?
You can also make the train look smaller with the -l option.
The sl program is a nice tool for correcting users who accidentally enter sl instead of ls. Making mistakes is not always bad, sometimes it is alot of fun.
