LOLcat: Terminals with rainbow colors

Below we will see why Linux can stand out by simply allowing any customization in the system. We will use the lolcat packet to convert the commands displayed in the terminal to a rainbow. Yes the commands will appear in rainbow colors in slow motion.

Interesting; Let's see how it works:lolcat

As I mentioned earlier, we will use the LOLcat application. The cat commands come with enhanced color and Rainbow-like colors.

The LOTcat application is available in virtually all modern Linux distributions by default at their repository. Alternatively, you can install the latest version of LOLcat from the git repository.

apt-get install ruby ​​[for systems with APT] yum install ruby ​​[for systems with Yum] dnf install ruby ​​[for DNF systems]
