SYNOPSIS

ddup [OPTION] PATH

DESCRIPTION

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.

OPTIONS

-d, --debug LEVEL

Set verbosity level. LEVEL can be one of: fatal, err, warn, info, dbg.

-v, --verbose

Run in verbose mode.

-q, --quiet

Run tool silently. No output is printed.

-h, --help

Print the command usage, and the list of options available.

EXAMPLES

  1. To report any duplicate files under a directory tree:

mpirun -np 128 ddup /path/to/haystack
