  -c, --changes
          like verbose but report only when a change is made
      --from <CURRENT_OWNER:CURRENT_GROUP>
          change the owner and/or group of each file only if its
          current owner and/or group match those specified here.
          Either may be omitted, in which case a match is not required
          for the omitted attribute
      --preserve-root
          fail to operate recursively on '/'
      --no-preserve-root
          do not treat '/' specially (the default)
      --quiet
          suppress most error messages
  -R, --recursive
          operate on files and directories recursively
      --reference <RFILE>
          use RFILE's owner and group rather than specifying OWNER:GROUP values
  -f, --silent

  -v, --verbose
          output a diagnostic for every file processed
  -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)
      --dereference
          affect the referent of each symbolic link (this is the default), rather than the symbolic
          link itself
  -h, --no-dereference
          affect symbolic links instead of any referenced file (useful only on systems that can
          change the ownership of a symlink)
  -V, --version
          Print version
