Both of these will stage all files, including new files (which git commit -a misses) and deleted files.

The difference is that git add -A also stages files in higher directories that still belong to the same git repository. Here's an example:

/my-repo
  .git/
 subfolder/

##Steps

$ rails g model User

belongs_to

has_one

These are a list of usages of shell commands I can't live without on UNIX-based systems.

Using Homebrew (yes, I am opinionated) you can install the following tools with the following packages:

	# Usage:
	# * export-chrome-cookie.sh
	# * export-chrome-cookie.sh <domain>
	# <domain> examples:
	# .google.com
	# %.google.com (SQLite wildcard)

	#Model

	@user.should have(1).error_on(:username) # Checks whether there is an error in username
	@user.errors[:username].should include("can't be blank") # check for the error message

	#Rendering
	response.should render_template(:index)

	#Redirecting
	response.should redirect_to(movies_path)

	'select host_key, "TRUE", path, "FALSE", expires_utc, name, value from cookies'
