The world of Linux is full of fun and surprises!
Today, let’s explore three amazing “Easter eggs” hidden in the Linux terminal: the Tropical Fish Tank, the Shell Train, and the Talking Cow.
These seemingly nonsensical little gadgets not only make your terminal lively and interesting but also allow you to show off your “geeky” side in front of your friends.
Have you ever thought about keeping a tropical fish tank in your boring terminal?
Yes, Linux can fulfill this wish! Just install a little tool called `asciiquarium`, and your terminal will instantly turn into a vibrant aquarium.
### Installation and Usage
First, you need to install `asciiquarium`. On Debian/Ubuntu systems, first, add the PPA so that apt can find the software:
sudo add-apt-repository ppa:ytvwld/asciiquarium
sudo apt update
You can install it with the following command:
sudo apt-get install asciiquarium
Once installed, just type in the terminal:
Then you will see an aquarium made of ASCII characters, with swimming fish, swaying plants, and even bubbles!
`asciiquarium` is not just a simple animation; it showcases the power of the Linux terminal—creating stunning visual effects through plain text.
Imagine, when you’re working in the terminal, suddenly switching to this little fish tank, doesn’t it instantly make you feel much more relaxed?
Of course, if you find it not enough, there’s an even more powerful aquarium – `xfishtank`, which is more realistic.
However, I haven’t found a way to “close the program” (only can “kill -9” it, haha)!
2. Train in the Terminal: `sl`
If you’ve ever accidentally typed `sl` instead of `ls` (list directory contents) in the terminal, you might have been “hit” by a sudden train!
Yes, there’s a steam train hidden in the Linux terminal, and its name is `sl`.
### Installation and Usage
On Debian/Ubuntu systems, you can install `sl` with the following command:
Once installed, just type:
Then, a steam train made of ASCII characters will slowly pass from the right side of your terminal, accompanied by a “toot toot” sound (if your terminal supports sound).
`sl` was originally designed to punish those who often mistyped `ls`, but it quickly became a classic Easter egg among Linux users.
Every time you see this train, it brings a smile.
It reminds you: be careful when typing!
3. The Cow in the Terminal: `cowsay`
In the Linux terminal, you can even make a cow talk to you!
Yes, this is `cowsay`, a tool that allows a cow (or other animals) to display custom text in the terminal.
### Installation and Usage
On Debian/Ubuntu systems, you can install `cowsay` with the following command:
sudo apt-get install cowsay
Once installed, try typing:
cowsay "Hello, Linux World!"
Then, you will see a cow talking to you in the terminal:
`cowsay` not only supports cows but also other animals and characters. You can check all available characters with the following command:
Then, choose a character you like, such as a dinosaur:
cowsay -f stegosaurus "Wakaka!"
4. Conclusion: The Fun and Power of Linux
Through `asciiquarium`, `sl`, and `cowsay`, we can see that Linux is not just a serious operating system; it is also a world full of fun and creativity.
These little “Easter eggs” not only make the terminal more vibrant but also let us feel the humor and wisdom of the Linux community.
Next time you are working in the terminal, why not try these little tools and add some fun to your work?
Who says geeks can’t have a childlike heart?
The world of Linux is far more colorful than you can imagine!
