chgrp staff /u

Change the group of /u to "staff".

chgrp -hR staff /u

Change the group of /u and subfiles to "staff".

chgrp byobushared /tmp/byobu-shared.session


Change the group of each FILE to GROUP. With --reference, change the group of each FILE to that of RFILE.
, --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)


do not treat ’/’ specially (the default)


fail to operate recursively on ’/’


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.


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 (default)


display this help and exit


output version information and exit
