SYNOPSIS

chgrp [OPTION]… GROUP FILE…
chgrp [OPTION]… –reference=RFILE FILE…

DESCRIPTION

group of each FILE to that of RFILE.

-c, –changes

-f, –silent, –quiet

-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

only on systems that can change the ownership of a symlink)

–no-preserve-root
do not treat ‘/’ specially (the default)

–preserve-root

–reference=RFILE
use RFILE’s group rather than specifying a GROUP value

-R, –recursive

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
