Mac OS X Hidden Files in Finder
Once in a while i need to see hidden files in Finder, unfortunately finder does not provide an option to show/hide hidden files. But you can use the following command to make it show/hide hidden files. Fire up a terminal and type,
To Show
defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder
To Hide
defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder
