       chgrp - change group ownership

       chgrp [OPTION]... GROUP FILE...
       chgrp [OPTION]... --reference=RFILE FILE...

       Change  the group of each FILE to GROUP.  With --reference, change the
       group of each FILE to that of RFILE.

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

              affect the referent of each symbolic link, rather than the sym-
              bolic link itself

       -h, --no-dereference
              affect  each symbolic link instead of any referenced file (use-
              ful only on systems that can change the ownership of a symlink)

       --no-preserve-root do not treat '/' specially (the default)

              fail to operate recursively on '/'

       -f, --silent, --quiet
              suppress most error messages

              use RFILE's group rather than the specifying GROUP value

       -R, --recursive
              operate on files and directories recursively

       -v, --verbose
              output a diagnostic for every file processed

       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

              output version information and exit
