never done regex in bash before, what im bascially trying to do is this perl/php regex
/(\d+)_\d+_\d+[_a-z]*\.jpg/i
what is gets is the facebook profile id, from a facebook image.
http://a1.sphotos.ak.fbcdn.net/hphot...20 4038_n.jpg
would get 80329313253
in php
preg_match('/(\d+)_\d+_\d+[_a-z]*\.jpg/i',$url,$matches);
match[1] would be the fb id
