A powerful duplicate file finder and an enhanced fork of fdupes.

# To search a single directory:
jdupes <directory>

# To search multiple directories:
jdupes <directory1> <directory2>

# To search all directories recursively:
jdupes --recurse <directory>

# To search directory recursively and let user choose files to preserve:
jdupes --delete --recurse <directory>

# To search multiple directories and follow subdirectores under directory2, not directory1:
jdupes <directory1> --recurse: <directory2>

# To search multiple directories and keep the directory order in result:
jdupes -O <directory1> <directory2> <directory3>
