@option{-d} option, duperemove will submit those extents for deduplication
using the Linux kernel extent-same @code{ioctl}.

Duperemove can store the hashes it computes in a @dfn{hash file}.  If given an
existing hash file, duperemove will only compute hashes for those files which
have changed since the last run.  Thus you can run duperemove repeatedly on
your data as it changes, without having to re-checksum unchanged data.

Duperemove can also take input from the @command{fdupes} program.")
