pdupes – Perl duplicate file finder and deduper

abstract

pdupes is a duplicate file detector that is inspired by jdupes, while having different design goals:

• jdupes has many configuration options and operation modes. pdupes is designed to do exactly one thing: dedupe rsnapshot backup archives.

• jdupes is designed to be extremely fast while using little memory. pdupes favors a small and simple codebase and more expensive higher language constructs over resource usage.

• pdupes functionality should be verified by automated tests.

usage

pdupes <directory> [<directory> ...]

pdupes will scan all files in the given directories and will then hardlink duplicate files to each other to consume disk space.

#TODO

• add deduplication: hardlink duplicate files, don't just print them

• add tangled POD

• add test cases

• add license/copyright

• add project URL and license badge
