    Great, thanks! Just one thing - I want the third input - STRING , to be the word that I look for and not replace with. If I don't put anything there I want the code to work as it is, and if I do I need it to look for STRING instead of looking for QUALIFIED_CLOCK...

      I was trying to replace the line mentioned with 
        next if ( $find_flag and ( if ($replacement == "") { /\s+QUALIFIED_C
+LOCK/ } else { /\s+$replacement/ } ));

      But it writes me "syntax error". I cant understand why... What I'm trying to do is check whether I entered a string and then look for it, and If not, look for QUALIFIED_CLOCK .

        like that? 
        my ($iFile, $oFile, $searchFor) = @ARGV;

$searchFor = quotemeta( $searchFor || 'QUALIFIED_CLOCK );
....

next if $find_flag and /\s+$searchFor/;
