Home: Perl Programming Help: Regular Expressions: Clarification with $+

perllearner Novice Aug 11, 2009, 11:17 PM Post #1 of 3 (4886 views) Clarification with $+ Can't Post Hi, Can any one please clarify what is meaning of the following 1.$& 2.$` 3.$' 4. In pattern matching I have seen they use this =~ /\b[A-Z]\S+/g, what is the meaning of \b.

spider User Aug 12, 2009, 1:01 AM Post #2 of 3 (4883 views) Re: [perllearner] Clarification with $+ [In reply to] Can't Post Subject: $+ returns whatever the last bracket match matched. 1. $& returns the entire matched string. 2. $` returns everything before the matched string. 3. $' returns everything after the matched string. 4. The \b is word boundary. Take a look at http://perldoc.perl.org/perlre.html
