Or you can learn regexes interactively: http://weitz.de/regex-coach/ http://weitz.de/regex-coach/ I personally use Emacs' regex-builder mode to get quick visual feedback on what a pattern matches on a given input data before I set it loose. (regex-coach is Perl compatible but emacs is not; I frequently type [0-9]+ in emacs to mean \d+)

The thing that drives me crazy about Emacs regexes (which I use nearly every day) is how their escaping behavior is opposite to everybody else's.
