in thread Detect common lines between two files, one liner from shell

I understand. But apparently, b hasn't read your book, and you shouldn't assume everyone who wants to/knows perl has. Since it's such a short, useful program, I'd think you wouldn't mind explainning it to those who don't understand it. After all, it's not like he was asking about a Shwartzian Transfom (though I doubt you'd mind explainning that).
