HardlinkPy

Scan for and hardlink identical files.

Effectively works to hardlink all indentical files where previous implementations of the hardlink command have failed with clusters of hardlinks.

Rewritten in Python 3 object-oriented code: new database structure and algorithm development for complete single-pass hardlinking, persistent database file option for testing, data collection on dry-run passes, and incremental scans.

Install (Linux)

sudo python3 ./hardlink.py --install
