How to install and use Zsh on Ubuntu

The command line is a powerful tool in the hands of a Linux user. However, the default shell, known as Bash, can sometimes lack the features or user-friendliness that some users desire. Enter Zsh: a shell designed to be interactive, user-friendly, and highly customizable. With features such as spell correction, improved auto completions, and a rich set of options for customizing its behavior, Zsh has gained popularity among developers and system administrators alike.
