history
Project history and usage
Periscope is an interactive duplicate-file management tool designed to help users understand where copies reside and remove them without losing the final copy of any data.
Project history
Anish Athalye developed Periscope as a duplicate-file finder focused on safe, interactive organization. The project uses an incremental scan followed by commands for exploring, refreshing, and removing duplicates.
Adoption history
Periscope is distributed as the `psc` command, including through Homebrew. Its shell-oriented design makes it suitable for users who want to inspect duplicate placement before deleting anything.
How it is used
Run `psc scan` over selected folders, inspect the resulting filesystem view with commands such as `psc ls`, and use `psc rm` to remove a file only when another copy exists. Run `psc refresh` after external deletions or another incremental scan after moving or adding files.
Why package nerds care
Periscope is distinctive among duplicate-file utilities because it models deduplication as an interactive filesystem workflow. Its duplicate-aware analogues of familiar commands let users reason about retained copies instead of immediately applying an automatic cleanup policy.
Timeline
- Public project era: Released as the `psc` command with scan, exploration, refresh, and duplicate-aware removal operations.
