oh-my-zsh with PowerLevel9k on Arch Linux

Attention: This is DEPRECATED in favor of PowerLevel10K, I wrote an article about it:

Change default shell on Arch Linux

Install oh-my-zsh with powerlevel9k theme on Arch Linux

This gist aims to facilitate the switching from bash to zsh as our defaut shell. We will be using oh-my-zsh with the powerful theme: Powerlevel9k. You will find all the links below. This process applies mainly for Arch Linux, but can be setup for any other distro (in theory :)). I'm also using Gnome Terminal and pacaur as package manager.

Resources

Zsh: https://wiki.archlinux.org/index.php/zsh
Default shell: https://wiki.archlinux.org/index.php/Command-line_shell#Changing_your_default_shell
Oh-my-zsh: https://ohmyz.sh/
Oh-my-zsh plugins: https://github.com/robbyrussell/oh-my-zsh/wiki/Plugins
Powerlevel9k theme: https://github.com/bhilburn/powerlevel9k
Nerd Fonts: https://nerdfonts.com/

Here is how the result looks like

Step 1: Install Zsh (if not currently using it)

pacaur -S zsh oh-my-zsh-git

Step 2: Make Zsh your default shell (restart so your shell change takes effect)

chsh -l
chsh -s /usr/bin/zsh

Step 3: Install the Powerlevel9k theme

$ sudo git clone https://github.com/bhilburn/powerlevel9k.git /usr/share/oh-my-zsh/themes/powerlevel9k

Step 4: Install Nerd Fonts Hack

pacaur -S nerd-fonts-hack

Step 5: Migrate from Bash (skip if you are already using it)

You will have to move some content from your files .bash_profile and .bashrc to .zshrc and .zprofile respectively.

Step 6: Theme configuration in .zshrc file (copy and paste :))

Step 7: Add more plugins if you want, here are mine

Step 8: Setup font in GNOME (skip if not a GNOME user)

Install GNOME Tweaks in case you have GNOME
Set the system monospace font to "Hack Nerd Font Regular"
In the Terminal's Font Preference, I leave the Custom Font option unchecked, .i.e use system font.
