Introduction

As someone who spends a lot of time in the terminal, I know how powerful it can be for developers, system administrators, and tech enthusiasts like myself. The terminal provides a direct interface to the operating system, but the default experience can often feel plain and lacking in features that boost productivity and ease of use. Thankfully, I discovered tools and customizations that transformed my terminal into a visually appealing and highly functional workspace.

One of the first tools I came across was Oh My Zsh, an open-source framework that makes managing Zsh configurations incredibly easy. Zsh, or Z shell, is a powerful alternative to the default Bash shell on macOS, offering enhanced features like better tab completion, command history, and scripting capabilities. Oh My Zsh takes it a step further with a vast array of plugins and themes that have made my terminal sessions more efficient and enjoyable.

To further enhance my workflow, I added Zsh Autosuggestions. This handy tool provides intuitive command suggestions, allowing me to quickly recall and reuse commands without typing them out completely. It's been a game-changer, saving me time and reducing the repetitive strain of retyping frequent commands.

Finally, I discovered Powerlevel10k, a theme that not only makes my terminal look great but also provides a wealth of information at a glance. From showing the current git branch to displaying system load, Powerlevel10k has become an essential part of my terminal setup.

In this article, I'll walk you through how I set up Oh My Zsh on macOS, integrated Zsh Autosuggestions to improve my command-line experience, and installed Powerlevel10k to give my terminal a sleek, functional appearance. Whether you're a terminal pro or just starting out, these tools can revolutionize your command-line experience, making it more efficient, visually appealing, and tailored to your needs.

Setting Up Oh My Zsh on macOS

Step 1: Install Zsh

To get started, I first needed to ensure I had the latest version of Zsh installed. While Zsh comes pre-installed on macOS, I used Homebrew to update it to the latest version. Here's how I did it:

brew install zsh
Enter fullscreen mode Exit fullscreen mode

Step 2: Install Oh My Zsh

Next, I installed Oh My Zsh using a simple installation script. I chose to use curl, but wget works just as well:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
Enter fullscreen mode Exit fullscreen mode

Step 3: Set Zsh as the Default Shell

After installing Oh My Zsh, I set Zsh as my default shell:

chsh -s $(which zsh)
Enter fullscreen mode Exit fullscreen mode

I then restarted my terminal for the changes to take effect.

Step 4: Customize Oh My Zsh

I opened my .zshrc file to customize my Zsh setup, including themes and plugins:

nano ~/.zshrc
Enter fullscreen mode Exit fullscreen mode

I set the theme to something I liked and added a few plugins to enhance my terminal's functionality. Once done, I reloaded my configuration with:

source ~/.zshrc
Enter fullscreen mode Exit fullscreen mode

Enhancing Zsh with Autosuggestions

Step 1: Install zsh-autosuggestions Plugin

To add autosuggestions, I cloned the zsh-autosuggestions repository into the Oh My Zsh custom plugins directory:

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
Enter fullscreen mode Exit fullscreen mode

Step 2: Enable the Plugin

I then enabled the plugin by editing my .zshrc file:

nano ~/.zshrc
Enter fullscreen mode Exit fullscreen mode

I added zsh-autosuggestions to the list of plugins:

plugins=(git zsh-autosuggestions)
Enter fullscreen mode Exit fullscreen mode

Step 3: Apply the Changes

Finally, I reloaded my Zsh configuration to activate the plugin:

source ~/.zshrc
Enter fullscreen mode Exit fullscreen mode

Now, I get helpful command suggestions as I type, which has sped up my workflow significantly.

Installing and Configuring Powerlevel10k

Step 1: Install Powerlevel10k

For a visually stunning terminal, I installed Powerlevel10k by cloning its repository:

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/themes/powerlevel10k
Enter fullscreen mode Exit fullscreen mode

Step 2: Set Powerlevel10k as the Theme

I then updated my .zshrc file to set Powerlevel10k as my theme:

nano ~/.zshrc
Enter fullscreen mode Exit fullscreen mode

I changed the theme line to:

ZSH_THEME="powerlevel10k/powerlevel10k"
Enter fullscreen mode Exit fullscreen mode

Step 3: Apply the Changes

After saving the file, I reloaded my Zsh configuration:

source ~/.zshrc
Enter fullscreen mode Exit fullscreen mode

Step 4: Configure Powerlevel10k

The first time I loaded the theme, Powerlevel10k launched a configuration wizard that helped me customize my prompt. If the wizard didn’t start automatically, I could trigger it manually with:

p10k configure
Enter fullscreen mode Exit fullscreen mode

This wizard allowed me to set up a prompt that displays essential information, making my terminal both beautiful and highly functional.

Conclusion

With Oh My Zsh, Zsh Autosuggestions, and Powerlevel10k, I’ve turned my macOS terminal into a powerful and aesthetically pleasing workspace. These tools have enhanced my productivity, made my workflow smoother, and added a personal touch to my terminal sessions. If you’re looking to improve your terminal experience, I highly recommend trying these tools out for yourself.
