jadupes – Java duplicate file finder and deduper

abstract

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

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

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

• jadupes functionality should be verified by automated tests.

It also also a direct descendant of my own, unfinished Perl variant of jdupes called pdupes: It turns out that currently I like Java and Eclipse refactoring tools more than cool classic Perl ;-)

usage

java jadupes.jar <directory> [<directory> ...]

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