Zsh Customizations and Useful Packages
I'm using Oh My ZSH (https://github.com/robbyrussell/oh-my-zsh) along with my own customizations.
Feel free to use any or all of these customizations for your command line.
I also use a lot of packages from Homebrew.
Note that the install script is highly customized for my setup.
