It can be good to write things down for yourself, to think them through. But I agree that to actually teach others Linus describes it much better, without the sprinkling of errors this post has. Like for example the author confuses the terminal for the shell. ctrl-w very much is passed right through to bash. But the author is correct if the user types "cat\n". Now it's the terminal handling ctrl-w. But note that cat doesn't handle ctrl-a. It's more complex than the author seems to think. tl;dr: read the other post, not this one.
