Customize your Chrome OS Terminal

Intro

Hey 👋 I already had a post written about my WSL setup, but I had uninstalled it like two weeks after writing the thing, so I don't really have any screenshots. But I recently purchased a Chromebook and upon getting it I was keen on testing its Linux features. I formatted it and why not provide a step by step guide on how to make your Chromebook terminal look like this. This also applies to most Linux terminals. For benchmarking reasons, I'm running a Lenovo C

Installing Zsh and Oh My Zsh

Linux on Chrome OS does not ask for a password whenever you use commands with super user access, so we first need to do this:

sudo su && passwd pushp.vashisht

In the same terminal window, we can install Zsh by writing 👇

sudo apt install zsh && chsh -s $(which zsh)

After we have Zsh, we need to install Oh My Zsh, which is a framework for managing Zsh. We already have curl, so just paste this on your terminal:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Type 'Y' to set your Oh My Zsh as your default bash. This command always creates a ~/.zshrc file on your home directory, which we'll alter soon. For now, your terminal should already look like this:

echo 'exec /usr/bin/zsh' >>~/.bashrc

Powerlevel9k Theme

I use the much lighter Powerlevel 10k Theme, which is also very easy to configure, however I wasn't able to install its required font, Meslo LG S, therefore, we're going with its older cousin P9K, which is a great theme, just a little harder to configure. To install it run this command:

git clone https://github.com/bhilburn/powerlevel9k.git ~/.oh-my-zsh/custom/themes/powerlevel9k

To change our zsh configuration we need to install a text editor, if you're like me and don't know how to vim, 👉 sudo apt install nano . After this, let's create and change our zsh config and tell it to use our Powerlevel 10k theme. Hit nano ./zshrc and change the ZSH_THEME line to the following 👉 ZSH\_THEME="powerlevel9k/powerlevel9k" . Hit Ctrl + X and 'Y' to save and exit. Press Ctrl + T to open a new terminal window and type zsh . You should already notice some differences.

Setting Terminal Theme & Font

As of this writing, it is no longer possible to add transparency or change custom fonts on the Chrome OS terminal. I've tried several methods, like installing gnome-terminal and terminator, but the result was a downgraded version of both terminals with anti-aliasing disabled. So I've settled for one of the built themes, Dusk, which in my opinion looks better than most 'stock' themes I usually see in terminals.

term_.prefs_.set('font-family', '"Source Code Pro", monospace');

In the end, you should end up with something like this 👇
