I'm having trouble using "$fileAge = -M $fileName" to determine age of files in a directory. Basically, I need to see if all the files in a directory are more than a day old. If they are, I process them. My problem is that whenever the fileAge is printed out, it's null and looks like this: "Filename=[result.896] file age = []" I should add that all the files I'm currently scanning are less than a day old for now. What am I doing wrong? 

    
# Test output files for age to see if they should be processed
# Start out assuming all output files may be parsed
my $filesAreOldEnough = 1;

if ( $numOutputFiles > 0 )
{
  foreach my $fileName ( @outputFiles )
  {
    my $fileAge = -M $fileName;
    print "Filename=[ $fileName ] file age = [ $fileAge ]\n";
    if ( $fileAge < 1 )
      {
        $filesAreOldEnough = 0;
        #last; # check all files for now
      }
    }
} else {
    # No input files to process, skip directory...
    $filesAreOldEnough = 0;
}
