Have a geeky terminal environment with ZSH

What is Zsh?

Zsh is a Unix shell used for command-line interpreting. It’s an alternative to the standard bash shell. One of the key features of Zsh is its advanced completion system, which can automatically complete commands, options, and filenames based on context and history. Zsh also provides a powerful syntax-highlighting feature that can highlight commands and arguments as you type them. Zsh is highly configurable and can be customized with many plugins and themes. It is often used as an alternative to the default shell on Unix-based systems, such as Bash or the Bourne shell.
