Installing and configuring the Oh My ZSH shell

Installation

I love using Oh My ZSH in my terminal to use with GIT. This works faster than GIT UI programs like Tower. First of all you need to install ZSH and afterwards install Oh My ZSH. The minimum zsh version required for Oh My ZSH is 4.3.9

Install ZSH first:

Git is required. If you don’t have git installed you can download it from this location http://git-scm.com/downloads

git clone git://zsh.git.sf.net/gitroot/zsh/zsh

Installing Oh My ZSH via CURL

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

Or install Oh My ZSH via WGET

wget --no-check-certificate https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | sh

If you don’t already have a ~/.zshrc file. You can create a file with that filename

Afterwards you can set ohmyzsh as your default shell:

chsh -s /bin/zsh

 All you need to do then is restart your terminal and it should be using ohmyzsh than. You can tweak your ohmyzsh in the .zshrc file. This is what my .zshrc file looks like:

# Path to your oh-my-zsh configuration.
ZSH=$HOME/.oh-my-zsh

# Set name of the theme to load.
# Look in ~/.oh-my-zsh/themes/
# Optionally, if you set this to "random", it'll load a random theme each
# time that oh-my-zsh is loaded.
ZSH_THEME="afowler"

# Example aliases
# alias zshconfig="mate ~/.zshrc"
# alias ohmyzsh="mate ~/.oh-my-zsh"

# Set to this to use case-sensitive completion
# CASE_SENSITIVE="true"

# Comment this out to disable weekly auto-update checks
# DISABLE_AUTO_UPDATE="true"

# Uncomment following line if you want to disable colors in ls
# DISABLE_LS_COLORS="true"

# Uncomment following line if you want to disable autosetting terminal title.
# DISABLE_AUTO_TITLE="true"

# Uncomment following line if you want red dots to be displayed while waiting for completion
COMPLETION_WAITING_DOTS="true"

# Which plugins would you like to load? (plugins can be found in ~/.oh-my-zsh/plugins/*)
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
plugins=(git)

source $ZSH/oh-my-zsh.sh

# Customize to your needs...
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin:/opt/local/bin
ZSH_THEME_GIT_PROMPT_PREFIX=" on %{$fg[magenta]%}"
ZSH_THEME_GIT_PROMPT_SUFFIX="%{$reset_color%}"
ZSH_THEME_GIT_PROMPT_DIRTY="%{$fg[green]%}!"
ZSH_THEME_GIT_PROMPT_UNTRACKED="%{$fg[green]%}?"
ZSH_THEME_GIT_PROMPT_CLEAN=""

 Here you can find a list of plugins to enable in your oh-my-zsh: https://github.com/robbyrussell/oh-my-zsh/wiki/Plugins 

I just used the git plugin here. Your terminal should now look something like this

• Git & Capistrano
• Mac and Apple stuff
