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
