Zsh

We'll install zsh for all the features offered by oh-my-zsh. The installation and usage is really intutive. The env.sh is a config file we maintain so as to not pollute the ~/.zshrc too much. env.sh holds aliases, exports, path changes etc.

Zsh

Install zsh and zsh completions using homebrew

brew install zsh zsh-completions

Now you can customize your shell using two frameworks Prezto or Oh My Zsh. So you should follow one of the two sections below. I personally prefer Prezto as that seems to have slightly better performance.

Prezto

Install prezto on top of zsh to get additional functionality

git clone --recursive https://github.com/sorin-ionescu/prezto.git "${ZDOTDIR:-$HOME}/.zprezto"

Next create the ~/.zshrc file by running

setopt EXTENDED_GLOB
for rcfile in "${ZDOTDIR:-$HOME}"/.zprezto/runcoms/^README.md(.N); do
  ln -s "$rcfile" "${ZDOTDIR:-$HOME}/.${rcfile:t}"
done

edit the ~/.zpreztorc file and add

zstyle ':prezto:load' pmodule \
  'environment' \
  'terminal' \
  'editor' \
  'history' \
  'directory' \
  'spectrum' \
  'utility' \
  'completion' \
  'git' \
  'syntax-highlighting' \
  'history-substring-search' \
  'prompt'

zstyle ':prezto:module:prompt' theme 'paradox'

edit the .zshrc by opening the file in a text editor and adding the following below

# Add env.sh
source ~/Projects/config/env.sh

Oh My Zsh

Note: You don't need this section if you installed Prezto.

Install oh-my-zsh on top of zsh to get additional functionality

curl -L https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh | sh

if you're still in the default shell, change default shell to zsh manually

chsh -s /usr/local/bin/zsh

edit the .zshrc by opening the file in a text editor

ZSH_THEME=pygmalion
