fddf

Fast data dupe finder

This is a small Rust command-line program to find duplicate files in a directory recursively. It uses a thread pool to calculate file hashes in parallel.

Duplicates are found by checking size, then SHA-1 of parts of files of same size, then a byte-for-byte comparison.

Build/install

Directly from crates.io with cargo install fddf.

From checkout: cargo build --release cargo run --release

Usage

``` fddf [-s] [-z]

-s: report dupe groups in a single line -z: report zero-length files a group of dupes ```
