chgrp - Man Page

change group ownership

Examples (TL;DR)


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


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)


change the ownership of each file only if its current owner and/or group match those specified here. Either may be omitted, in which case a match is not required for the omitted attribute


do not treat '/' specially (the default)


fail to operate recursively on '/'


use RFILE's ownership rather than specifying values RFILE is always dereferenced if a symbolic link.

-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. '-P' is the default.


if a command line argument is a symbolic link to a directory, traverse it


traverse every symbolic link to a directory encountered


do not traverse any symbolic links


display this help and exit


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".
