chgrp - change group ownership

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

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

chgrp staff /u

Change the group of /u to “staff”.

chgrp -hR staff /u

Change the group of /u and subfiles to “staff”.
