How to install Fish shell in Fedora Linux?

A Unix shell is a program that interprets the command or script and acts as an intermediary between the user and kernel of the system. Bash, zshcsh, and fish are some examples of Unix shells.

The fish (friendly interactive shell) is a smart and user-friendly Unix shell. Its syntax is derived neither from the bourne shell nor from the c shell, so it is considered an exotic shell.

Unlike many other shells that disable many features by default to save system resources, the fish shell enables many of them to provide more features to its users.

In this article, I will discuss how to install and use the Fish shell in Fedora Linux.
