ddup [OPTION] PATH
Parallel MPI application to report files under a directory tree having identical content.
ddup reports path names to files having identical content (duplicate files). A top-level directory is specified, and the path name to any file that is a duplicate of another anywhere under that same directory tree is reported. The path to each file is reported, along with a final hash representing its content. Multiple sets of duplicate files can be matched using this final reported hash.
