## What it is
rmlint is an extremely fast command-line tool written in C that finds duplicate files and directories, broken symlinks, empty files, nonstripped binaries, and other filesystem lint. It offers many output formats, caching/replay, and BTRFS support to help remove space waste.

## Use cases
- find and remove duplicate files on my disk
- free up disk space by deduplicating files
- find broken symlinks and empty directories
- fdupes alternative that is faster
- detect duplicate directories in a filesystem
- clean up filesystem lint like broken ownership

## When to choose
- you need a very fast, scriptable duplicate finder on Linux
- you want non-interactive cleanup with many output formats
- you need BTRFS-aware deduplication

## When to avoid
- you need an interactive GUI duplicate cleaner
- you primarily work on Windows
- you want automatic deletion without reviewing generated scripts
