If you’re a geek, you probably know how to use the command line interface. This is the way it used to be prior to the GUI (graphical user interface). Most real CLIs don’t work with a mouse, you just type text into the computer. Try it here (you can use your mouse for some things with this version).
kukukuan has written a WordPress plugin (so I don’t have to manually change the code in CLI 2.3) that allows readers of this blog to use a command line interface using Rod McFarland’s CLI 2.3 WordPress theme.
