sl: The train burns, people scream.
$ sl -a

The command "sl -a" is a playful command in Unix-based systems that displays a simple animation of a train (Steam Locomotive) moving across the terminal. The "sl" stands for "steam locomotive," and the "-a" option is used to enable the animation.
When you run "sl -a" in the terminal, a small ASCII art representation of a steam locomotive will appear, complete with smoke, moving from left to right across the screen. It is just a fun command and doesn't serve any specific practical purpose.

never run a command you are not sure if it is safe.
