Install zsh on Manjaro i3

This is how to quickly and easily get up and running with zsh on Manjaro i3. First, check the shell you are currently using:

[manjaro@manjaro ~]$ echo $SHELL
/bin/bash

Install zsh:

[manjaro@manjaro ~]$ sudo pacman -S zsh

However this might not be necessary because it looks like as of Manjaro 20.0.1, zsh is installed now by default, and looks pretty good

Switch to zsh:

[manjaro@manjaro ~]$ zsh
manjaro@manjaro Linux 5.6.12-1-MANJARO x86_64 20.0.1 Lysia
~ >>> 

Then exit to quit again.

~ >>> exit                                                                              
[manjaro@manjaro ~]$

To install Oh My Zsh, you’ll find it in the AUR:

~ >>> pamac search --aur oh-my-zsh
oh-my-zsh-git                                                               r5620.31eca46ee-1       AUR 
    A community-driven framework for managing your zsh configuration.
    Includes 180+ optional plugins and over 120 themes to spice up your
    morning, and an auto-update tool so that makes it easy to keep up with
    the latest updates from the community

And then install it with:

~ >>> pamac build oh-my-zsh-git

However to use it, you have to copy /usr/share/oh-my-zsh/zshrc to ~/.zshrc. First we backup the original one:

~ >>> cp -v .zshrc .bkp_zshrc-orig                                                                     
'.zshrc' -> '.bkp_zshrc-orig'
~ >>> cp -v /usr/share/oh-my-zsh/zshrc .zshrc                                                          
cp: overwrite '.zshrc'? yes
'/usr/share/oh-my-zsh/zshrc' -> '.zshrc'

Then exit, and then zsh again:

~ >>> exit                                                                                             
[manjaro@manjaro ~]$ zsh
➜  ~ 

To enable zsh-syntax-highlighting and zsh-autosuggestions, first make sure they are installed and then add the following two lines to your ~/.zshrc.

source /usr/share/zsh/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
source /usr/share/zsh/plugins/zsh-autosuggestions/zsh-autosuggestions.zsh

Lastly, you;ll want to make sure you change your default shell:

➜  ~ chsh -s $(which zsh)
Changing shell for manjaro.
Password: 
Shell changed.
