Updating perl howto

You can define more than one range inside a list, for example, [0-9A-C] means check for 0 to 9 and A to C (but not a to c).NOTE: To test for - inside brackets (as a literal) it must come first or last, that is, [-0-9] will test for - and 0 to 9.For example, [12] means match the target to 1 and if that does not match then match the target to 2 while [0123456789] means match to any character in the range 0 to 9.The - (dash) inside square brackets is the 'range separator' and allows us to define a range, in our example above of [0123456789] we could rewrite it as [0-9].From doing a little research: FLEXnet Connect is a solution that Acresso sells to software vendors that is designed to help you stay connected with your customers after they install your applications.

Most applications, utilities and laguages that implement RE's, especially PERL, extend the ERE capabilities and what are typically called PERL Compatible Regular Expressions (PCREs) have, largely, become a de facto standard.These are Browser ID Strings and appear as the Apache Environmental variable HTTP_USER_AGENT (full list of Apache environmental variables).We are going to try some simple matching against our example target strings: Note: You can also experiment as you go through the examples.You are either into hieroglyphics big time - in which case you will love this stuff - or you need to use regular expression, in which case your only reward may be a headache. Here is a definition of our terms: A literal is any character we use in a search or matching expression, for example, to find ind in windows the ind is a literal string - each character plays a part in the search, it is literally the string we want to find.A metacharacter is one or more special characters that have a unique meaning and are NOT used as literals in the search expression, for example, the character ^ (circumflex or caret) is a metacharacter.
