	# 2024-06-26 - AWK Recipe

	I manage a collection of about 80,000 or so recipes. Most of them
	are in a plain-text format used by the Meal-Master recipe manager.
	The top line is supposed to be something like:

	MMMMM----- Recipe via Meal-Master (tm) v8.06

	The other day i found one that had a few unwanted lines on top. It
	was probably a "copy paste" error from years ago. I hand fixed the
	recipe format, but wanted to search my collection to see whether any
	other recipes needed to be fixed.

	I wrote a quick awk script to report whether a file has lines before
	the Meal-Master signature, then i ran it on the whole database. To
	my surprise, it took less than 10 seconds to search all 80k recipes.

	$ find moar/ascii -type f \| xargs awk '
	/via [Mm]eal-[Mm]aster/ { if (FNR > 1) found[FILENAME] = 1 }
	END { for (fn in found) print fn }' >rlis

	It found a total of 35 other recipes that needed to be fixed.

	What's my point? I got a kick out of how quickly i arrived at a
	solution using awk. It was easy and effective.

	By the way, i tried it using gawk, mawk, and nawk, and got the
	same results in all three.
