chgrp - change group ownership

Synopsis

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

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

--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 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 ‘/’

-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 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

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

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