It's very rarely best to use a range expression as it makes trivial programs very slightly briefer than using a flag but then causes you to have duplicate conditions (as in this case) or a complete rewrite if the problem gets the tiniest bit more complicated. See also awk.freeshell.org/AllAboutGetline for when/how to use getline.
