-c, --changes
       like verbose but report only when a change is made

       itself

-v, --verbose

The following options modify how a hierarchy is traversed when the -R option is also specified.  If  more
than one is specified, only the final one takes effect.
-H     if a command line argument is a symbolic link to a directory, traverse it
-L     traverse every symbolic link to a directory encountered
-P     do not traverse any symbolic links (default)
--help display this help and exit
--version
