     ID.

     -R   Recursively change the group ownership  of  directories
          and their contents.  (And continue even when errors are
          encountered.)


GNU OPTIONS

     -c, --changes
          Verbosely describe the action for each file whose group
          actually changes.

     -f, --silent, --quiet
          Do not print error messages  about  files  whose  group
          cannot be changed.

     -h, --no-dereference
          Act on symbolic links themselves instead of  what  they
          point  to.  Only available if the lchown system call is
          provided.

     -v, --verbose
          Verbosely describe the action or non-action  taken  for
          every file.

     -R, --recursive

          cessfully.

     --version
          Print version information on standard output, then exit
          successfully.
