      Hi,
      $s='finding related pages finding on the world wide web'; my $count=$s=~ m/finding/g; print $count;

      I expect the result as 2.. becus "finding" exists two times in $s. but the output is 1. Why??

      thanks

        It is because you don't know how to copy/paste

        The extra  ( ) = are required --- probably the worst syntax in all of perl, but its what you need if you have built-in regexes without objects, and you don't store matches in an array.
