The sl command allows the train to run on the Linux Desktop

The sl command is an interesting command for running trains on Linux desktops.

A common mistake you make is to input ls into sl. I have set an alias, that is, alias sl = ls. However, you may have missed this steam train with a whistle.

Sl is a funny software or Unix game. It will show a Steam train passing through your screen after you mistakenly input "ls" into "sl" (Steam Locomotive.

It also exists on Freebsd and other Unix-like operating systems.

Next, let's mistake ls to sl:

$ Sl

Figure: If you enter "ls" as "sl", the steam train will go through your screen.

It also supports the following options:

-A: It seems that an accident has occurred. You will feel sad for those who cry for help.
-L: displays a smaller train.
-F: it actually flew away.
-E: Ctrl + C interrupt allowed
