UNIX – Terminal – Oh My Zsh Setup

# If on something other than Mac you may need to do 'apt install git zsh' or the equivalent 

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

cat .zshrc | grep ZSH_THEME
sed -i '.original' 's/ZSH_THEME="robbyrussell"/ZSH_THEME="avit"/gp' ~/.zshrc
cat .zshrc | grep ZSH_THEME

As much as I like Oh My Zsh sometimes you have to go back to original terminal as not all things are supported.

cd ~/
sh .oh-my-zsh/tools/uninstall.sh
rm -rf .oh-my-zsh
rm -rf .zsh-update
rm -rf .zsh_history
rm -rf .zshrc
rm -rf .zshrc.*
rm -rf .zcompdump*
chsh -s /bin/bash

NOTE: This is part of a setup I do for new computers, see HomeBrew – Mac OS Setup
