In the book, I mention that the Cordova CLI doesn't put any output to the console unless something goes wrong or if the -d (debug) parameter is included on the command line. Well, after Cordova 3.0, the development team made me a liar by changing the CLI so it generates output by default instead. So, where I show that nothing goes to the console, that's inaccurate, now all sorts of information is sent to the console for all (most) CLI commands.
