NAME

chgrp − Changes the group ownership of a file or directory

SYNOPSIS

chgrp [−fR] group file

The chgrp command changes the group associated with the specified file or directory to group. 

DESCRIPTION

If you do not own the file and do not belong to the new group, you must have superuser authority to change the group name or group ID. 

The group argument must be either a valid group name or a valid group ID that exists in the group database. 

FLAGS

−fSuppresses all error reporting. 

−RCauses chgrp to descend recursively through its directory arguments, setting the specified group ID.  When symbolic links are encountered, their group is changed, but they are not traversed. 

EXAMPLES

To change the group ownership of the file or directory named proposals to staff, enter:

chgrp staff proposals

The group access permissions for proposals now apply to staff. See chmod for details.
