## What it is
Rdfind is a command line utility that finds duplicate files by comparing file content rather than names. It can help reclaim disk space by identifying redundant data, e.g. in backup directories.

## Use cases
- find duplicate files on disk
- clean up backup directories with redundant copies
- free up disk space by detecting identical files
- compare files by content not filename
- deduplicate a photo or media collection

## When to choose
- you need a fast, mature CLI tool for content-based duplicate detection
- you want a simple Unix-style tool available in distro package managers
- you are cleaning up backups or large file trees

## When to avoid
- you need a GUI duplicate finder
- you need fuzzy/similar (not exact) duplicate matching
- you need automatic deduplication with dedup filesystem features

## Facets
- artifact type: cli-tool
- maturity: stable
- function: file-system, cli, compression
- domain: files, developer-tools
- platform: cli, cross-platform
- tags: duplicate-files, disk-cleanup, deduplication, command-line, linux, macos
