So I just wrote one for personal use. I was looking for a duplicate file/photo finder and read some reviews about losing data so I said why would I trust a third party for my data and wrote a dupe finder. Use a hash (md5) to make a match (it is not perfect but it works) and then sort and print to show me the dupes. The first version was 45 lines of code although I could have reduced lines if I tried. You don't need awk strictly but I used it to prettify my output and add some filters. Current code with lots more bells and whistles is less than 150 lines (including white space) of bash and awk. And it works for me and I trust it. I could set up a database, write multiple layers of code ... but really?
