I made this console emulator for children to get used to the black screen.
I actually wrote this console for my 5 year old brother. I decided to put the code on Github as I thought others might benefit as well.
Teaching
When you type ls command, you will see two and three letter commands listed. Ask the child to perceive the listed commands and find and type them on the keyboard.
