pub(crate) fn main()Expand description
Scans one or more directories for duplicate files and prints groups sorted by total disk space used (size × occurrence count).
Each group lists the human-readable total size, the SHA-256 hash, and every path sharing that hash.
§Errors
Exits with a non-zero status if fewer than one directory argument is provided. Individual file-hashing errors are printed to stderr and do not halt the scan.
