in reply to search =~ for /'s

Everyone has advised you to use a regex so far. However, when you know the position in the string to check for, substr is often a better method, as it is clearer and potentially has a lower overhead.

$new .= '/' unless substr $new, -1 eq '/';

    $new .= '/' unless substr $new, -1 eq '/'; can someone explain what -1 does
      see perlman:perlfunc
      # 1st argument given: string to process # 2nd argument given: offset # so here it means regardless of the true length the # last character in the string substr ($new, -1);
