Nice code. I saw something in your code that I was doing, and lately converted. These lines: 

  #use default directory if argument not set on command line
  find(\&fileop, $opts{'directory'}) unless @ARGV;
  find(\&fileop, @ARGV) if @ARGV;

Your use of if and unless are creating a more compact form of if (...){} else {} for calling &find. I love statement modifiers, but I now use the following form: 
  #use default directory if argument not set on command line
  find(\&fileop, @ARGV ? @ARGV
                       : $opts{'directory'});

That way, with a true if/else variant, I never screw up the logic and inadvertently create overlapping conditions, which were difficult to debug.

Yes, Aristotle said the same thing, but the key, I think, is not the needless redundancy of the code, but the danger of creating those overlapping conditions.
