My script doesn't yet exist, although when created it would, yes. I was thinking of just making a BASH script and using dd to extract 512 byte chunks of files, pipe through md5sum and save the result in a large index file. Next just iterate through the index file looking for duplicate hashes. In fact that sounds so easy I might do it right now... (only to proof of concept stage - a real utility would probably want to be written in a compiled language and use proper trees for faster searching) -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
