Greetings all I have a problem to pass an operator as an argumnt to a sub, like this: 
&checkDir('/usr/tmp', '-w');      #or...
&checkDir('/usr/tmp', '-r')

sub checkDir {

  my ($dir, $perm) = @_;

  ### Check if output dir exists
  if (! defined $path) {
    LOG ("The path where to save the output is not defined using temp 
+instead...", 1);
    $path = '/var/tmp/';
   }
  if (! -d $path) {
    die LOG ("$path is not a valid directory...", 0);
  }
  if (! $perm $path) {
    die LOG ("You do not have $perm to $path directory...", 0);
  }
  LOG ("Using $path as output directory...", 2);
}

I have tried to deref the $perm var, but it does not help either. Is it possible at all to pass an operator as an argument?? Cheers and thanks Pär
