dupd - A fast and convenient CLI tool for finding duplicate files

dupd is a file duplicate detection CLI utility.

The build currently supports Linux (tested on Debian), Solaris (tested on OpenIndiana), OpenBSD, FreeBSD and Mac OS X. Other UNIX variants should work with minimal effort.

dupd seeks to be fast and efficient. For most file sets it performs better than other popular tools.

Aside from performance, the other primary advantage of dupd is that it enables a more exploratory style of discovering duplicate files instead of simply dumping out a big list as the other popular duplicate finder tools do (although dupd can also do that, if you really want).

For older released versions, refer to the archived releases on github.

Latest development snapshot

Check out the source from github and refer to the BUILDING file for more info.

Most of the time the latest sources should be buildable but bear in mind the master branch is a work in progress so it might not always work.

For most use cases, I recommend using the latest released version (see above) unless you really need the very latest changes.
