While I'm not sold on this particular concept, it does highlight a feature of modern Unices which bears pointing out: the command-line environment isn't some dreadful primitive thing that should only be relied on as a last resort.<p>Rather, it's the evolutionary end-point of some 40+ years of continuous improvement in issuing and processing text-based information streams (both commands and outputs), in a very powerful, highly flexible, extremely adaptable manner.<p>The age of "Oh, Linux, that's like DOS" are far beyond us. But it bears pointing out that this is much like comparing a pogo stick to an F-22 / Boeing 777 / Mercedes E-class. Yeah, the both get you places. How, how much, at what speed, and in what style ... differ.
