How To: OS X Mavericks show hidden files and folders

Seems Apple has changed showing and hiding files in OS X Mavericks as the casing is a bit different..

Show Hidden:
Filesdefaults write com.apple.finder AppleShowAllFiles TRUE
Then:
killall Finder

and to hide them:
Filesdefaults write com.apple.finder AppleShowAllFiles FALSE
Then:
killall Finder
