Here’s an example of using regex in Perl effectively:


        <![CDATA[
        # Perl regex example
        my $text = "The quick brown fox jumps over the lazy dog.";
        if ($text =~ /quick.*fox/) {
            print "Match found!";
        } else {
            print "No match.";
        }
        ]]>
