Re: bitwise AND against a variable containing Fnctl constants not returning desired results

In Your code:

return unless $dirStats[2] & $mask == $mask;
[download]

Do you mean:

 return unless ($dirStats[2]) & ($mask == $mask);
[download]

 return unless ($dirStats[2] & $mask) == $mask;
[download]

or something else entirely?

Parenthetical aside: the Perl interpreter makes guesses about intent based on the Precedence Rules. You can use parentheses to explicitly say what you want and remove the guess-work.
