Show hidden files in OS X Finder

Mac OS X Finder does not show hidden (.dot) files and folders. Usually administrator will go in the Terminal and browses those hidden files and folders. This command will display all hidden files and folders.

defaults write com.apple.Finder AppleShowAllFiles -bool true

To make the command take effect, you need to restart the Finder.

killall Finder

Revert to the default setting:

defaults write com.apple.Finder AppleShowAllFiles -bool false

Restart Finder
