Both behave in the same way as their find(1) equivalents.

Avoids returning results from inside any directory called <dirname>

--dir=<dir>

Add a directory to search. May be repeated multiple times. For backwards

compatibility, if no --dir argument is provided then all but the last entry

in <filenames> are treated as directories.
