Dearest Monks,

I have near-duplicate files in deeply nested directories. The duplicates are appended with " 1" as in "Mack the Knife 1.mp3". The duplicates are found together in the same directories. I would like to be able to locate potential duplicates (with regex), then check to see if a counterpart (without the " 1" is located in the directory. If the counterpart exists, rename. If not, then it's not a "duplicate", so do nothing. The best I can do is find the " 1.mp3" files and move them. How can I check for the counterpart? TIA.

#!/usr/bin/perl -w
use strict;

use File::Find;
find(\&process, '/Users/Shared/Music');

sub process {
    if (/[\d\D]*(?<!No\.)\s+1.mp3$/) {
        rename "$File::Find::name", "/Users/wrinkles/dupes/$_"
        or die $!;
        print "$File::Find::name removed. \n";
    }
}

The regex checks for a trailing " 1" that is not preceded with "No.". If I can check against the counterpart file, the look-behind check for "No." won't be necessary.
