Setup a beautiful terminal using zsh and ohmyzsh

ZSH = Z Shell is an extended version of the Bourne Shell (sh), with plenty of new features, and support for plugins and themes.

Oh-My-Zsh = is a plugin for zsh, it include many themes and addons.

1. Installing zsh

Debian:

$ sudo apt install zsh

Fedora

$ sudo dnf install zsh

2. Setup zsh

You will see this

This is the Z Shell configuration function for new users,
zsh-newuser-install.
You are seeing this message because you have no zsh startup files
(the files .zshenv, .zprofile, .zshrc, .zlogin in the directory
~).  This function can help you with a few settings that should
make your use of the shell easier.

You can:

(q)  Quit and do nothing.  The function will be run again next time.

(0)  Exit, creating the file ~/.zshrc containing just a comment.
     That will prevent this function being run again.

(1)  Continue to the main menu.

(2)  Populate your ~/.zshrc with the configuration recommended
     by the system administrator and exit (you will need to edit
     the file by hand, if so desired).

--- Type one of the keys in parentheses --- 

Input ‘2’ and it will create a file “~/.zshrc”

3. Installing Oh-my-zsh

$ sh -c "$(wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh -O -)"
