smugmug-cli

smugmug-cli (the sm command) uploads photos to SmugMug from the command line. Give it files or whole directories and it files them into albums by the day they were taken, skips anything already uploaded using hash-based deduplication, and uploads concurrently.

It can also run scheduled backups of a library, re-reading only the files that changed. Install it with cargo install smugmug-cli, or run the multi-architecture Docker image from GitHub Container Registry.
