CHGRP(1) CHGRP(1) NAME chgrp - change file's group or owner SYNOPSIS chgrp [ -uo ] id file ... DESCRIPTION Chgrp changes the group ownership of each file to the given id, if the file's server permits it. The -u and -o options are equivalent and cause chgrp to change file ownership instead, if the file's server permits it. Normally, 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, but var- ious underlying devices, file servers and host operating systems might not permit the operation at all. Group and ownership changes allowed by a given device are documented by the device's manual page. See sys-stat(2) for the varia- tions amongst host operating systems.
