Periscope is a command-line duplicate file finder that helps you organize storage and safely remove redundant files without losing data.
Instead of only producing a static report, it is designed for interactive use from the shell, letting you inspect duplicates while navigating the filesystem with familiar commands. Its workflow makes it easier to understand where duplicate copies live, review them, and delete only files that have another copy elsewhere.
This is free and open source software.
Key Features
- Interactive duplicate file finder designed for use from the command line.

- Provides duplicate-aware commands such as ls, info, tree, report, and summary.
