Installing oh-my-zsh on Raspberry Pi

How to install oh-my-zsh on Rasbian Buster and a few useful plugins to get started

Installing oh-my-zsh on Raspberry Pi

Why ZSH?

oh my zsh is wonderful, and really makes the rest of life better when ssh-ing into your Raspberry Pi.

How do I explain it... bash is to zsh as a regular, original unconfigured vi is to a nicely configured modern vim.

To put it in MIB venacular, bash isn't "old and busted" - but zsh is definitely the new hotness.

All I can say, is if you haven't tried it - it's difficult to explain just how much better life is with ZSH than without it.

Those who have tried it know exactly what I'm talking about - so I'll shutup and get to how to make it happen quickly.

It's actually quite simple and straight forward.

Overview

Okay, so this is actually really easy. You're doing three things.

  1. Making sure the latest version of zsh is installed
  2. Installing oh-my-zsh
  3. Installing and tweaking a few plugins

How to install oh-my-zsh

Install zsh

1. Update your Raspberry Pi

... if you haven't recently (like... within the last hour or so, even then it's probably still a good idea.)

sudo apt-get update && sudo apt-get upgrade
sudo apt-get update && sudo apt-get upgrade

2. Install git and zsh

sudo apt-get install git zsh

(To Answer "Yes" when it asks, hit enter... I always type the answer I want, I don't know why.)

sudo apt-get install git zsh

3. Make zsh your default shell

chsh -s /bin/zsh
chsh -s /bin/zsh
Password:

It will ask for your password... type it in.

Okay, we're close, but we're not done yet. You have zsh sure... but oh-my-zsh is basically a package manager for a bunch of super great improvements and basic zsh configuration.

If you were to log out and log back in right at this particular moment, you will see something like 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 ---

If you do, just type q and hit enter.

When you install oh-my-zsh it will configure your zsh for you. So let's do that now.

4. Install oh-my-zsh

Feel free to check out the installation line at -> https://github.com/robbyrussell/oh-my-zsh we're just use the curl method to install oh-my-zsh.

Here's the install line as of today:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

... Congratulations! and Welcome to the New Hotness!

We're almost done. Just a few plugins to get you started and you're off to the races.


Install and tweak a few plugins

Okay, so most guides on how to do this stop here... but I'm cooler than them - so I'm going to show you what oh-my-zsh is all about and give you a few oh-my-zsh plugins that are really worth having.

  1. zsh-syntax-highlighting
  2. zsh-autosuggestions
  3. zsh-completions

TODO: clean up the installation instructions for all three of these plugins - and a few tweaks for zsh-syntax-highlighting.

Open ~/.zshrc in your favorite editor

vi .zshrc

Uncomment the 2nd line where it sets your path.

# export PATH=$HOME/bin:/usr/local/bin:$PATH

Becomes

export PATH=$HOME/bin:/usr/local/bin:$PATH

And replace the line that says

plugins=(git)

With this:

plugins=(git zsh-completions zsh-autosuggestions zsh-syntax-highlighting)
autoload -U compinit && compinit

Now quit vim :wq then hit enter

Now logout.

exit

(you may have to type exit again)

exit
uberbuilder% exit
Connection to uberbuilder.local closed.

Now login again to your Pi, and you're done!

Enjoy.


Now, welcome to your super new and improved zsh shell.

... your welcome :)
