Switching to Zsh is not about abandoning familiar concepts, but rather about upgrading to a more powerful and user-friendly terminal experience. Let's get started with the installation process.

Basic Installation

The installation process for Zsh is straightforward and varies slightly depending on your operating system. Here are common methods for macOS and Linux:

macOS

macOS usually comes with Zsh pre-installed, especially in recent versions. You can verify this by opening your terminal and typing:

        zsh --version
    

If Zsh is not installed or you need a newer version, you can use package managers like Homebrew or MacPorts.

Using Homebrew:

        brew install zsh
    

Using MacPorts:

        sudo port install zsh
    

Linux (Debian/Ubuntu)

On Debian-based distributions like Ubuntu, you can install Zsh using apt:

        sudo apt update
sudo apt install zsh
    

Linux (Fedora/CentOS)

For Fedora or CentOS based systems, use yum or dnf:

        sudo dnf install zsh
    

or

        sudo yum install zsh
    

Setting Zsh as Default Shell

After installation, you'll likely want to make Zsh your default shell. This ensures that every new terminal window or tab you open uses Zsh.

Use the chsh command (change shell) to set Zsh as your default. You'll typically need to provide the path to the Zsh executable, which is often /bin/zsh or /usr/bin/zsh. To find the exact path, you can use the which zsh command.

        which zsh
    

This will output the path to your Zsh executable, for example: /usr/bin/zsh.

Now, use chsh with the output path:

        chsh -s /usr/bin/zsh
    

After running this command, you'll likely need to enter your user password. Once done, close your current terminal and open a new one. Zsh should now be your default shell!

Next Steps

With Zsh installed and set as your default shell, you've completed the initial setup! In the following sections, we'll explore customization options, themes, plugins, and tips to truly unlock the power of Zsh and tailor it to your workflow.

Basic Setup

Ready to unlock the power of Zsh? Getting started is simpler than you might think. This section will guide you through the initial setup, ensuring you have Zsh up and running as your default terminal shell. Let's dive in!

Is Zsh Installed?

First things first, let's check if Zsh is already installed on your system. Most macOS systems come with Zsh pre-installed, but it might not be the default shell. Open your terminal application and type the following command:

    
zsh --version
    
  

If Zsh is installed, you'll see the version number printed in the terminal. If you get an error message like "zsh: command not found", you'll need to install it.

Installing Zsh

The installation process varies slightly depending on your operating system. Here are instructions for common systems:

macOS

If you're on macOS and Zsh isn't already installed or you want to ensure you have the latest version, you can use Homebrew, a popular package manager. If you don't have Homebrew installed, follow the instructions on their website to install it first. Once Homebrew is set up, open your terminal and run:

    
brew install zsh
    
  

Linux (Debian/Ubuntu)

On Debian-based Linux distributions like Ubuntu, you can install Zsh using apt:

    
sudo apt install zsh
    
  

Linux (Fedora/CentOS)

For Fedora, CentOS, and other Red Hat-based distributions, use yum or dnf:

    
sudo dnf install zsh
    
  

Windows (using WSL)

If you are using Windows Subsystem for Linux (WSL), you can install Zsh within your Linux distribution just like you would on a native Linux system. Follow the Linux instructions above based on your WSL distribution (e.g., Ubuntu).

Setting Zsh as Default Shell

After installing Zsh, you'll likely want to make it your default shell. This means that every time you open a new terminal window, Zsh will be the shell that starts.

You can change your default shell using the chsh command (change shell). To set Zsh as your default, type:

    
chsh -s $(which zsh)
    
  

You'll be prompted to enter your password. After entering your password, close your current terminal window and open a new one. To verify that Zsh is now your default shell, run:

    
echo $SHELL
    
  

This should output the path to your Zsh executable, confirming that it's now your default shell.

First Run and Configuration

When you run Zsh for the first time as your default shell, it might present you with a configuration wizard, especially if there's no existing Zsh configuration file in your home directory (usually ~/.zshrc).

The wizard typically offers a few options to initialize your Zsh configuration. For a basic setup, you can usually choose to create a default configuration file. You can always customize it further later.

Congratulations! You've completed the basic setup of Zsh. In the next sections, we'll explore customization options, themes, and plugins to truly unleash the power of Zsh.
