A number of months back I switched from Linux (Gentoo) to a Mac at work. Over the months I have been slowly tweaking settings to make it work the way I like my environment to be. I however should have been making notes on what I have changed/found. I will now start trying to do this.
The below is taken from Terminal Tips: Enable “path view” in Finder
To make directory paths visible atop Finder windows, open Terminal.app (/Applications/Utilities/) and type the following command:
defaults write com.apple.finder _FXShowPosixPathInTitle -bool YES
You then will need to restart the Finder.
