Cd Deluxe - improved cd command for *nix and windows
Hello, Take a look at this free cd replacement - "cd deluxe" a.k.a. "cdd". It is a free open source (GPLv3) application that I have created. As a long time command line enthusiast I have always been frustrated with the limited capabilities of the humble "cd" command. Especially since that is the most commonly used command line utility! See http://www.plan10.com/cdd for the full details and download information. Thanks, -Mike
