They are fully described in books like "Programming Perl" by Wall, Christiansen and Orwant (pub. O'Reilly), known as "The Camel Book". Alternatively, you can find online descriptions by searching for "Perl regular expression", "Perl regex" or "pcre". There are several flavours of regular expression in use, so its important to learn about the right one. Martin
