Beautify Your Terminal: Embrace the Colors of the Rainbow with Lolcat

For anyone who spends a significant amount of time in the terminal, having a visually appealing workspace can make a big difference. Enter lolcat - the fun, colorful utility that outputs text in rainbow colors, turning your plain terminal into a vibrant display. Whether you're a seasoned developer or a complete beginner, if you're on the hunt for a way to inject some whimsy into your command line sessions, lolcat is a great choice. In this blog post, we'll explore what lolcat is, how to install it using various package managers, and some amusing examples of how to use it.

What is Lolcat?

Lolcat is a utility for Linux and Unix-like systems that concatenates similar to the cat command but adds a rainbow coloring effect to the output text. It's written in Ruby, and while it doesn't add any functional advantage, it does make the output more delightful and visually stimulating. It can be used in a variety of ways to brighten up the scripts, output, or even to just echo everyday commands.

Lolcat is not just limited to echoing plain text. It can be piped with commands and scripts to give you a colorful output which can be very handy for distinguishing between different sections of output or just to liven up standard gray text.

Installing Lolcat

Lolcat is available in the repositories of most Linux distributions and can be installed with just a few commands. Below, find the instructions tailored for various package managers.
