hardlink

Consolidate duplicate files by replacing them with hard links. Part of util-linux, useful for saving disk space when identical files exist across directories. More information: https://manned.org/hardlink.

• Simulate hardlinking duplicate files without modifying them:

hardlink {{[-n|--dry-run]}} {{path/to/directory}}

• Hardlink duplicate files in a directory:

hardlink {{path/to/directory}}

• Hardlink duplicate files in multiple directories:

hardlink {{path/to/directory1 path/to/directory2 ...}}

• Display verbose output while hardlinking:

hardlink {{[-v|--verbose]}} {{path/to/directory}}

• Only consider files with a minimum size:

hardlink {{[-s|--minimum-size]}} {{size}} {{path/to/directory}}
