Securely Empty The Trash By Default

You can empty the OS X trash securely by choosing the Secure Empty Trash option from the Finder menu. However, you can configure the empty trash option to be a Secure Empty Trash operation. To do so, write an EmptyTrashSecurely key into the com.apple.finder.plist. Use defaults to write the key into this plist as follows:

defaults write com.apple.finder EmptyTrashSecurely -bool true
