Wonder when that crept in. I've been using it for at least a decade, so it's probably been around at least twice that long. ...So probably came out about twenty years after the sed and awk feature sets were frozen. :) > I'm not entirely sure how I feel about that -- in terms of > readability, I'm not sure if the following is more readable: > > /(a[^z]*z)/ Wait till you see the other PCRE stuff. There are lots of things that really make it much more powerful. perlre(1) covers it all, sketchily and not really in order. I've said elsewhere, and will repeat again: "Mastering Regular Expressions" by Jeffrey E. F. Friedl (the owl book) is amazing. My first edition (1997) does not have some of the newer Perl stuff, but it's now up to a third edition: http://shop.oreilly.com/product/9780596528126.do
