Let’s dive into the fun side of Linux – its Easter eggs! Think of them as little surprises the developers baked into the system a playful wink to those who take the time to look.
Over the years I’ve discovered quite a few and I’m happy to share my favorites with you.
We’ll cover everything from quirky commands to hidden games so grab your keyboard and let’s explore!
The “Fortune” Cookie of the Command Line
Ever wished for a little daily inspiration or a good chuckle while working on your Linux machine? The fortune
command is your answer.
It’s a simple yet charming way to inject some humor or wisdom into your terminal sessions.
First you’ll need to install the necessary package.
The exact command depends on your distribution but for most Debian-based systems (like Ubuntu) you’ll likely use sudo apt-get install fortune-mod
. This installs a wide variety of quotes and jokes.
Now simply type fortune
at the command line and hit Enter.
You’ll be presented with a random quote.
It’s a fantastic way to start your day or take a quick refreshing break.
The sheer variety of sayings ensures you’ll encounter something new and interesting every time.
Don’t be surprised if you find yourself running this command multiple times a day – it’s surprisingly addictive! The randomness keeps it fresh and engaging.
You can further customize the experience by exploring different fortune databases.
These databases contain different collections of quotes and sayings.
A simple command like fortune -a
often reveals a list of available databases allowing you to fine-tune your daily dose of wisdom or humor.
You can specify which database to draw from making it even more personalized.
For example if you prefer jokes you might find a database specifically for jokes ensuring a constant stream of laughter in your terminal sessions.
It’s a delightful addition to a potentially monotonous command-line interface.
Meet the ASCII Cow: cowsay
Next on our list is the ever-charming cowsay
. This delightful command lets you generate ASCII art of a cow speaking your chosen message.
It’s incredibly simple to use and adds a splash of personality to your terminal.
Installation similar to fortune
varies by distribution.
For Debian-based systems it’s usually sudo apt-get install cowsay
. Once installed type cowsay "Your message here"
(replacing “Your message here” with your own text). The result is an ASCII cow with a speech bubble containing your message.
It’s pure unadulterated fun a great way to lighten the mood and a surprisingly useful tool for adding a touch of whimsy to your communications – especially in collaborative environments.
The beauty of cowsay
lies not just in its simplicity but in its extensibility.

Numerous extensions add different cow characters or even entirely new animal designs.
Explore these extensions; you might discover a dragon a cat or even a quirky-looking sheep.
Each animal will deliver your message within a speech bubble adding a lot of creative freedom and variation to your communication.
You can have a whole menagerie of talking animals enhancing your terminal experience.
It’s a surprisingly versatile tool that transforms simple text into creative and memorable ASCII art.
Beyond the Basic Cow: cowthink
and More
While cowsay
is entertaining it’s just the beginning.
There’s cowthink
which displays the cow in a thought bubble adding a different tone to your message.
This adds a layer of nuance to the communication suitable for expressing contemplations or uncertainties rather than declarative statements.
It allows for a more subtle and reflective tone.
Many more variations exist.
By searching online forums or your distribution’s package manager you’ll likely uncover a wealth of further options each offering a different animal or a unique graphical representation.
These options extend the creative possibilities of this simple command far beyond what one might initially expect.
It allows you to create customized messages with a variety of animals adding a unique and personal touch to your interaction with the Linux terminal.
Hidden Games: Snake and Tetris in Your Terminal
Who knew your terminal could be a gaming arcade? Linux often includes hidden games including classics like Snake and Tetris.
The installation process and exact command names might vary based on your Linux distribution.
For Debian-based systems you might need to install packages like snake
and tetris
(or equivalent names depending on your package manager’s repository) using the apt-get
package manager.
Then simply running the command name (snake
or tetris
) may launch the game directly.
However it’s not uncommon to need to create aliases for ease of access particularly in some Debian-based systems.
For instance you might need to edit your .bashrc
file (using a text editor like nano
) adding lines like alias snake='caca-snake'
or alias tetris='bastet'
. Save the file and you’ll have convenient access to the games via a simple command.
The game names might be slightly different depending on the available package in the repositories.
The addition of an alias simply provides a shortcut making it easy to access and launch the game in a simple way.
It provides a simple and convenient way to play classic arcade games on your Linux system.
Navigating Game Installations and Variations
The exact package names might differ slightly based on your distribution and its repositories.
It’s crucial to refer to your distribution’s documentation or community forums to confirm the precise package names to install.
Some distributions might even offer graphical front-ends for these games rather than the text-based versions described above.
So research might be required to find and install the correct games for your particular distribution.
Also don’t assume all distributions will have these included – if not a little online searching for alternative terminal-based games may reveal a multitude of options.
It’s important to be flexible and explore any alternative approaches if your initial attempts don’t work as expected.
