This page describes the syntax of regular expressions in Perl. If you haven't used regular expressions before, a quick-start introduction is available in perlrequick, and a longer tutorial introduction is available in perlretut. For reference on how regular expressions are used in matching operations, plus various examples of the same, see discussions of m//, s///, qr// and ?? in "Regexp Quote-Like Operators" in perlop.
