About:
fdupes is a command-line utility that scans specified directories to identify duplicate files based on their MD5 hash signatures. It compares file sizes and MD5 hashes to find exact duplicates, offering options to list, delete, or link duplicate files. This tool is essential for reclaiming disk space and organizing files by removing redundant copies.

Key Features:

Fast MD5 hash-based duplicate detection
Recursive directory scanning
Interactive or automatic deletion/processing
Hard-linking support to save space without data loss

Use Cases:

Cleaning up large photo or media libraries with duplicate downloads
Reducing backup sizes by identifying redundant files
Organizing shared network drives or file servers

Alternatives:

rmlint – More modern, supports more duplicate types (orphans, reflinks), and includes a safety-focused UI.
jdupes – A fork of fdupes with performance improvements and additional features like btrfs support.
