2013-11-06 - Regular Expressions Fundamentals, Moe Nasser
18:45, Suspenders Bar and Restaurant
Abstract

This meeting will cover regex basics, and based on audience participation, it may go well beyond.

A regular expression (regex) is a sequence of characters describing a search pattern. Regular expressions can match just about anything. Their power can shorten code, turbo-charge your use of interactive UNIX shells, and change the way you use your text editor. And, they're fun. Regular expressions are everywhere. Regular expression processors exist in every programming language, and they are fundamental to grep(1), sed(1), awk(1)- as well as UNIX shells. Classic text editors have regex processing at their core, vi(1), emacs(1), based on ed(1). You may even use regular expressions without consciously knowing it!
