BrowserUK's solution implies that you want to do something with a file if it contains one of the words 'PASS', 'sweeps', 'Final', but from your post, I take it a file should match all three of them. The following code snippet should do that. 

   open(FILE, "$some_dirr/$file")
       or die("can't open $file");
   my ($PASSmatch, $sweepsmatch, $Finalmatch);
   while (<FILE>) {
       if (/\bPASS\b/) {
           $PASSmatch = 1;
       } elsif (/\bsweeps\b/) {
           $sweepsmatch = 1;
       } elsif (/\bFinal\b) {
           $Finalmatch = 1;
       }
   }
   close(FILE);
   if ($PASSmatch && $sweepsmatch && $Finalmatch) {
       # do whatever with this file.
   }

This is not going to win a prize for elegance or generality, but it should be along the lines you want.

Hope this helps, -gjb-

Update: graff makes two good points about the code above: 1) one shouldn't die in a directory scan when a file can't be read and 2) it would be more efficient to last out of the while as soon as the three words have been found for efficiency's sake.
