10 Fun Linux Command-Line Programs You Should Try When Bored

The Linux terminal is a powerful utility. You can use it to control the whole system, crafting and typing commands as you go about doing your everyday tasks. But it can quickly become overwhelming to keep staring at a command line and carry on with your work.

Lucky for you, the terminal is also a source of fun. You can play around with commands, listen to music, and even play games. Although expecting a great deal of entertainment from a window full of commands would be carrying it too far, you can find utilities to bind some time when bored.

Here are some fun and entertaining commands every Linux user should try at least once.

1. CMatrix

Starting off the list with a fun tool every Linux user loves, CMatrix is a command-line utility that generates the classic “The Matrix” animation from the popular movie franchise of the same name. You can expect to see some great animations in different colors that you also get to customize.

Albeit CMatrix uses regular fonts instead of the original Japanese characters, you’ll definitely enjoy every moment you spend with the tool. Either use it as your desktop screensaver or include the program in your window manager rice screenshots, the choice is yours. You can even go to the extremes and set up a CMatrix server on a laptop that runs the program 24/7.

To install Cmatrix on Debian-based distros like Ubuntu:

sudo apt install cmatrix

On Arch Linux and its derivatives:

sudo pacman -S cmatrix

On RHEL-based distros like Fedora:

sudo dnf install cmatrix

2. cowsay

What does the cow say? Definitely, not just “moo.”

cowsay is an ASCII-art-based command-line utility that displays the specified input with a neat ASCII cow art. While there’s not much to this program, you can use it as a Bash prompt by invoking the program with random quotes whenever you launch a terminal instance.
