I found a video of the children having a good time in their computer classroom. I don't know where they are, but I guess it's in Indonesia or Malaysia. Video please take your own ladder: Https://youtu.be/z8taQPomp0Y

Run the train under the Linux terminal

There is no magic here. Just a command-line tool called "SL". I think it was developed for fun in the case of LS wrong. If you have ever worked on a Linux command line, you will know that LS is one of the most commonly used commands, and perhaps one of the most frequently-missed commands.

If you want to get some fun from the train under this terminal, you can install it using the command below.

1.sudo Apt-get Install SL

To run a terminal train, simply enter SL in the terminal. It has the following options:
-a: Unexpected mode. You will see the cry of the rescued masses
-l: show a smaller train but there are more carriages
-f: A flying train
-e: Allow CTRL + C to pass. Use other modes you cannot use CTRL + C to interrupt the train. However, it cannot be run for long periods of time.

Under normal circumstances, you should hear the whistle but it doesn't work on most Linux systems, and Ubuntu is one of them. This is an unexpected terminal train.
