A good starting point is: type ?regex in your console. Furthermore search in the net for "regular expression". http://en.wikipedia.org/wiki/Regular_expression http://en.wikipedia.org/wiki/Regular_expression_examples http://www.regular-expressions.info/ There are some variants of regexp engine on the market but the core syntax should be the same.
