I would use NR instead of FNR here simply because FNR has the additional complexity that it will reset to 1 when working on the next file, but when used to process a pipe stream it is in-essence working on a single file (/dev/stdin) and thus NR and FNR are always aligned making the use of FNR a bit of a bogon
