 -d action, --directories=action
         Specify the demanded action for directories.  It is `read' by default, which means that the directories
         are read in the same manner as normal files.  Other possible values are `skip' to silently ignore the
         directories, and `recurse' to read them recursively, which has the same effect as the -R and -r option.

 -s, --no-messages
         Silent mode.  Nonexistent and unreadable files are ignored (i.e. their error messages are suppressed).
