xxSherly
A fork of Sherly, using xxHash.
This fork is faster, but has less features and may produce false-positives.
Introduction
Sherly is a Multithreaded Duplicate File Finder for your Terminal, written in java. You can Easily find duplicate Images, videos as well as any other type of Data. That can be helpful if you run on small storage or just want to keep regular housekeeping.
Instead of md5, this fork uses xxHash + the filesize to find duplicates, for performance reasons (see Speed comparison). Note that xxHash is not a cryptographic hash function and therefore may produce collisions (false-positives). For this reason, since version 2.1, the program no longer offers the option to delete duplicates. You should delete them by yourself.

Speed comparison
I let Sherly and xxSherly find duplicates in my Music Library (containing .wav files) using the following commands:
time java -jar Bin/sherly.jar -n -f ~/Music/
time java -jar target/xxSherly-x.y-jar-with-dependencies.jar -n -f ~/Music/
The timings are measured using the Linux tool time (real).
