BONUS: here’s some command-line toys that are not useful or necessary, but are just real fun to take a look at especially if you’re new to linux:

• cmatrix (does the matrix code rain thing)
• cowsay (ascii cow with speech bubble)
• sl (steam locomotive in your terminal)
• cbonsai (generate bonsai tree)
• neofetch (this one is actually very useful and will print system information in an aesthetically pleasing way)
