## What it is
FDUPES is a command-line program written in C for identifying duplicate files within specified directories, with options to recursively search, compare by signature cache, and interactively delete duplicates. It supports filtering by size, hidden files, symlinks, and hardlinks.

## Use cases
- find duplicate files in a directory tree
- delete duplicate files to free disk space
- recursively scan folders for identical files
- summarize how much space duplicates consume
- exclude empty or hidden files from duplicate search
- speed up repeated duplicate scans with a signature cache

## When to choose
- you need a fast, lightweight CLI tool to find or remove duplicate files on Unix-like systems
- you want interactive selection of which duplicates to keep
- you need recursive scanning with size, symlink, and hardlink controls

## When to avoid
- you need a GUI duplicate finder
- you need fuzzy or near-duplicate detection (e.g., similar images)
- you are on a platform without a C compiler or POSIX environment

## Facets
- artifact type: cli-tool
- maturity: stable
- function: cli, file-system, developer-tools
