Linux and Unix nischown command
Change the owner of a NIS+ object.
nischown [-A] [-f] [-L] [-P] owner name
|-A||Modify all entries in all tables in the concatenation path that match the search criteria specified in name. It implies the -P option.|
|-f||Force the operation and fail silently if it does not succeed.|
|-L||Follow links and change the owner of the linked object or entries rather than the owner of the link itself.|
|-P||Follow the concatenation path within a named table. This option is only meaningful when either name is an indexed name or the -L option is also specified and the named object is a link pointing to entries.|
