sfdupes dwim, as sneak ordered: with no arguments it runs what scan / runs with no flags, default excludes on, then what trees runs, printing the duplicate trees largest first on stdout. Its last line, on stderr, says that sfdupes trees prints the report again. It needs no setup beyond what scan creates. SIGINT or SIGTERM during the scan stops it as it stops scan, exit 1, with no report; during the report a signal ends it at once, as it ends trees. A positional argument is a usage error, exit 2.
