duperemove
Finds duplicate filesystem extents and optionally schedule them for deduplication. An extent is small part of a file inside the filesystem. On some filesystems one extent can be referenced multiple times, when parts of the content of the files are identical. More information: <https://markfasheh.github.io/duperemove/>.
