    Forward

This will be the steps to setup my (very opinionated) shell
  environment.  Many things may go wrong (environmental variables,
  paths, etc), but this could be a great learning opertunity.
Use the man command for help!  Man pages are viewed in less, try
  man less to learn how to navigate them better!
Setup

Install Nix Package Manager

curl https://nixos.org/nix/install | sh
Restart your shell to refresh the environment.
Install Packages

nix-channel --add https://nixos.org/channels/nixpkgs-unstable
nix-channel --update

nix-env -i coreutils zsh oh-my-zsh
Append the following to ~/.zshrc and restart your shell:
if [ -e $HOME/.nix-profile/etc/profile.d/nix.sh ]; then
    . $HOME/.nix-profile/etc/profile.d/nix.sh
fi
export MANPATH="$MANPATH:$NIX_LINK/share/man"
In your terminal preferences, set /bin/zsh to run at startup and
  restart it.
Edit ~/.zshrc to customize zsh, give it a read.
Theme

The theme I use in zsh is sunrise.
I suggest setting your terminal theme to solarized.  Readable themes
  makes your pair partner happy.
Font

I suggest using Anonymous Pro Bold in terminals (20+ pt) and
  programming (18+ pt).  Large fonts makes your pair partner happy.
About

Zsh

Semi-backwards compatible with Bash, but with much better interactive
  support.
Oh-my-zsh

Community driven framework for managing zsh.  Has many themes,
  plugins, and shortcuts.
Coreutils

The core GNU command line tools. These are shell powertools and make
  your OSX command line more standardized.  Read about them here.
Scripting

Use ~/.zsh_funcs to store functions you write, and ~/.zsh_aliases
  to store your shell aliases.
Aliases

Here is a helpful function (with completion support) for working with
  aliases:
# ~/.zsh_funcs

save_alias () {
    cmd=`alias $1`
    echo alias $cmd >> ~/.zsh_aliases
}


_save_alias () {
    temp=`alias | sed -e 's/=.*//'`
    _arguments "1:alias:($temp)"
}

compdef _save_alias save_alias
Here is is an example:
# Alias a commonly used command
$ alias rl='readlink -f'

# Try it out
$ pwd
/Users/Carl

$ rl symlinkDir
/Users/carl/projects/realDir

# Save it for future use
save_alias rl
