Setting Up ZSH on FreeBSD

In this tutorial, I show you how to install ZSH and how to extend the ZSH shell with ohmyzsh.

What is ZSH

ZSH is the Swiss army knife of shells. It combines the most popular features of all other shells and can be customized to our needs. Users of Bourne and C-style shells will feel right at home. ZSH offers smart completion, and spell checking and is fully extensible through plug-ins.

We can install ZSH with the following command:

$: doas pkg install zsh

To be able to use ZSH as the default shell we have to do the following:

$: chsh -s zsh <username>

What is ohmyzsh

ohmyzsh is an open-source community-driven framework for managing our zsh configuration.

It provides plugins for things like ansible, bazel, git, tmux, etc. It is fully customizable and offers dozens of different themes.

Sounds boring. Let's try it again.

ohmyzsh won't make us a 10 times faster developer.... but it will make us feel like one.

Here's how we can install it:

$: doas pkg install ohmyzsh

If we have an existing ZSH configuration file, we will back up it first with the following command:

$: cp ~/.zshrc ~/.zshrc.orig

Then we create a fresh ZSH configuration file:

$: cp /usr/local/share/ohmyzsh/templates/zshrc.zsh-template ~/.zshrc

You are welcome to take a closer look at the configuration file, it's pretty well documented, and please have no hesitation to customize it to your liking.

ohmyzsh also comes with many pre-made themes, just have a look here, and you can easily change it in the configuration file.

Furthermore, ohmyzsh can be extended by plug-ins. Currently, there are about 270 plug-ins available. You can see the list here. Just have a look, there are many useful plug-ins available.

My ZSH shell currently looks like this.
