C-R was one of a few watershed moments for me. I discovered it over a decade a go as a cow-orker was flying through commands way faster than was humanly possible. "How did you do that?". And so I learned.
It, along with other readline functionality, shell functions, substitutions, expansions, scripts, and the bazillion utilities are what make Linux (and Unix) shell so much more than just "it's like DOS, right?".
Yeah, kind of, in the same way that ... a cross between a Prius, a Mack Truck, an Lamborghini, an F-16 fighter, a helicopter, and a freight train are like a pushcart. It's an interface that helps you manage your computers, the things on them, and the things they're connected to. It's also a hugely efficient and effective way to process information and issue commands and controls in a useful way.
