Viewing Hidden Files and Folders in Mac OS X
Introduction
By default Mac OS X doesn’t show any hidden files or folders. If you want to see everything, follow these steps.
Usage
Show all hidden objects:
$ defaults write com.apple.Finder AppleShowAllFiles TRUE
Swap TRUE with FALSE to turn it off again. Note: Finder must be relaunched afterwards to see the effect. For example like this:
$ killall Finder && open /System/Library/CoreServices/Finder.app
