NAME

chgrp − change file group

SYNOPSIS

­chgrp [ ­-ou ] ­group file ... 

DESCRIPTION

The group of each named file is changed to group, which should be a name known to the server holding the file.

A file’s group can be changed by the file’s owner, if the owner is a member of the new group, or by the leader of both the file’s current group and the new group. 

The ­-o and ­-u option are synonyms; they specify that the ­owner is to be set, rather than the group.  They are ineffectual unless the file server is in the bootstrap state that permits changing file ownership.
