  • Encrypted storage: Works with encryption keys for secure storage

Prerequisites

The CLI automatically checks for required tools (ImageMagick, FFmpeg) and prompts for installation if needed.

Error Handling

  • All commands provide colored output for better readability
  • Progress indicators show real-time status
  • Safe interruption (Ctrl-C) with graceful cleanup
  • Detailed error messages with verbose logging option

  4. List database contents: psi list --db ~/my-photos (or psi ls --db ~/my-photos)
  5. Verify database integrity: psi verify --db ~/my-photos (or psi ver --db ~/my-photos)
  6. Create backup/replica: psi replicate --db ~/my-photos --dest ~/backup/photos (or psi rep --db ~/my-photos --dest ~/backup/photos)
  7. Configure cloud storage (optional): psi configure (or psi cfg)
  8. Analyze specific files: psi info photo.jpg (or psi inf photo.jpg)

  10. Remove unwanted assets: psi remove --db ~/my-photos <asset-id> (or psi rm --db ~/my-photos <asset-id>)

This CLI provides a complete workflow for managing media databases from initialization through replication, verification, analysis, export, and removal.
