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

ence, 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, rather
than the symbolic link itself (this is the
default)
-h, --no-dereference
affect each symbolic link instead of any refer-
enced 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 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 tra-
versed 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
