Dupster is a terminal-first duplicate file finder built for developers, system administrators, and power users who live in the command line.
Inspired by Vim’s keyboard-driven workflow, it delivers a fast, distraction-free way to find and clean duplicate files.
This is free and open source software.
Key Features
- Content-Based Detection – Uses SHA-256 hashing—not filenames or sizes—to find true duplicates.
- ZIP Archive Scanning – Detects duplicates inside ZIP files without extracting.
- Interactive TUI – Full-screen terminal interface with keyboard shortcuts.
- Safe Deletion – Preview deletion plan and potential space reclaim before executing.
- Bulk Operations – Keep one per group or bulk delete with confirmation.
- Open in Viewer – Launch files in default application directly from TUI.
- Progress Tracking – Real-time scanning progress with file counts.
- Async Scanning – Non-blocking file system traversal for responsiveness.
- Cross-platform support – Runs under Linux and macOS.
