Efficient symlink removal script #2

I need to delete subdirectories up to the $dir if the file deleted was the last one in the particular subdir

in other words, if /base/a/c contains only aa.zip and it's outdated, delete the file, rmdir /base/a/c, if there are no more files/directories in /base/a, delete /base/a


Here is the script:

#!/usr/bin/perl
                                                                               
use strict;
use File::Find;

my $now = time;
my $hours = 10; # how old a file gets before it is deleted
my $age = $hours * 60 * 60; # $hours in seconds

my $dir = '/base'; # where to start from

find(\&wanted, $dir);

sub wanted {
return unless -l; # only handle symlinks

my $file_age = (lstat)[8];

 if ($file_age < $now - $age) {
   print "Deleting old file: $_ (", scalar localtime $file_age, ")\n";
   unlink;
 } else {
   print "Not deleting new: $_ (", scalar localtime $file_age, ")\n";
 }
}
