Show all files in OS X’s finder

By default the finder in OS X does not show all the files. You can still see the files if you use a terminal and type ls -la but sometimes you may need the finder to point to a particularly file. e.g. you want to load a hidden file in to an application. To force finder to show all files, just type the following into a terminal: defaults write com.apple.Finder AppleShowAllFiles YES
