Give a directory, find all transitive subdirectories of which two or more duplicates exist.
Two directories are considered a duplicate of each other if their sha256 checksums are equal. A directory's sha256 checksum is calculated from the concatenation of the following content of the directory:
- all file names
- all file contents
- the targets of all symlinks (links are not followed)
- all direct subdirectory names
- the sha256 of its direct subdirectories
To avoid clutter, only those duplicate directories are printed for which at least one parent directory has a different hash from the others. This avoids printing duplicate directories for which their parents are also all the exact duplicate of each other.
The output format has 4 or more columns separated by tabs. The first column
lists the diskusage as it would be returned by
du -b. The second column lists
the amount of elements in this sub directory tree as it would be returned by
find | wc -l. All subsequent columns list the duplicate directories with the
