CHGRP(1)           User Commands                  CHGRP(1)

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

       --dereference
          affect the referent of each symbolic link (this is the default),
          rather than the symbolic link itself

       -h, --no-dereference
          affect each symbolic link 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 ‘/’

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

       --reference=RFILE
          use RFILE’s group rather than specifying a 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

       --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".
