| ### Parent of the _n (_p) The _p variable holds the parent of the name stored in _n . The _n variable holds the name or list of names used in the argument to the most recent operation (see Most Recent Operation Argument Name (_n) ). The _p variable holds the name or list of names that are hierarchically above the name in _n (closer to the cell root). One use of the _p variable is in traversing up a CDS hierarchy of directories. Another use is showing the access control list (ACL) of a parent object. For example the following operations view the ACLs of a server configuration object and of its parent object (/.:/hosts/krypton/config/srvrconf ). dcecp> acl show /.:/hosts/krypton/config/srvrconf/video_clip {appl_admin cdfrwx} {unauthenticated r} {any_other r} dcecp> acl show $_p {appl_admin criI} {unauthenticated r} {any_other r} dcecp>
