Installing zsh

zsh is now the default shell in os X Catalina). You will only need to install it if you have an older OS version, or have upgraded.

Install

• Install Homebrew (if you haven’t already)

  /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  brew doctor
  

• Install zsh

  brew install zsh
  

• Set zsh as your default shell

  sudo sh -c "echo $(which zsh) >> /etc/shells" && chsh -s $(which zsh)
  

Migrating from Bash

If you are coming changing over from bash, you should make sure that your paths from bash are available in zsh.

in your zshrc (~/zshrc):

# PATH
export PATH=$HOME/bin:/usr/local/bin:$PATH

# JAVA
export JAVA_HOME=$(/usr/libexec/java_home)

# Python
export PATH=~/Library/Python/3.6/bin:$PATH

# RVM (Ruby version Manager)
# Add RVM to PATH for scripting. Make sure this is the last PATH variable change.
export PATH="$PATH:$HOME/.rvm/bin"
