Howto show system directories in Finder

Apple is hiding a lot of the directory structure from the regular user.
If for some reason you need to see everything in Finder you can configure this with the following:
defaults write com.apple.finder AppleShowAllFiles True; killall Finder
To revert to the default setting:
defaults write com.apple.finder AppleShowAllFiles False; killall Finder
