CHGRP(1)                      User Commands                     CHGRP(1)

NAME         top

       chgrp - change group ownership

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

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

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