DPNS-CHOWN(1)							DPNS User Commands						     DPNS-CHOWN(1)

NAME
dpns-chown - change owner and group of a DPNS directory/file in the name server SYNOPSIS
dpns-chown [-h] [-R] owner[:group] path... dpns-chown [-h] [-R] :group path... DESCRIPTION
dpns-chown sets the owner and/or the group of a DPNS directory/file in the name server to the values in owner and group respectively. To change the owner ID, if the group ID does not change and if the caller and the new owner ID belong to that group, GRP_ADMIN privilege is needed, otherwise the caller must have ADMIN privilege in the Cupv database. To change the group ID, the effective user ID of the process must match the owner ID of the file and the new group must be in the list of groups the caller belong to or the caller must have ADMIN privilege in the Cupv database. owner is either a valid username or a valid numeric ID. group is either a valid group name or a valid numeric ID. path specifies the DPNS pathname. If path does not start with /, it is prefixed by the content of the DPNS_HOME environment variable. OPTIONS
The following options are supported: -h If path is a symbolic link, changes the ownership of the link itself. -R Recursive mode. EXIT STATUS
This program returns 0 if the operation was successful or >0 if the operation failed. SEE ALSO
