NAME

   chgrp - change group ownership

SYNOPSIS

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

DESCRIPTION

   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

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

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

   --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)

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

   --preserve-root
          fail to operate recursively on '/'

   --reference=RFILE
          use RFILE's group rather than specifying a GROUP value

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

   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
          output version information and exit

EXAMPLES

   chgrp staff /u
          Change the group of /u to "staff".

   chgrp -hR staff /u
          Change the group of /u and subfiles to "staff".
