Zsh (Z Shell) is a powerful shell that provides interactive features and improvements over Bash, the default shell in most Linux distributions. In this blog post, we will explore how to set up and customize Zsh in Linux.

Installing Zsh

Before you can start configuring Zsh, you need to install it on your Linux system. The installation process may vary depending on your Linux distribution, but most distributions provide Zsh in their package repositories.

Ubuntu/Debian

Open a terminal and run the following command to install Zsh:

sudo apt-get install zsh

Fedora

To install Zsh on Fedora, run the following command:

sudo dnf install zsh

Arch Linux

On Arch Linux, you can install Zsh with the following command:

sudo pacman -S zsh

Setting Zsh as the Default Shell

After installing Zsh, you can set it as your default shell by running the following command:

chsh -s $(which zsh)

This command will change the login shell to Zsh for the current user. You will need to log out and log back in for the changes to take effect.

Look for the ZSH_THEME line and change the value to your desired theme. For example, to set the theme to agnoster, update the line to:

ZSH_THEME="agnoster"

Save the changes and restart the terminal to apply the new theme.
