UPDATE options COMPONENTS name-component
This command is unimplemented. Its form is not final; this section on it has not been significantly revised in about two years. If you wish to implement it in your server or have a need for it, please contact info-prospero@ISI.EDU.
This command tells the server to check each of the named components in the current directory for forwarding pointers. If the referenced object has moved, the link will be updated. The server will send Prospero protocol messages across the network to the targets of links to Prospero objects in order to check whether the target of a link has moved. (External links and symbolic links will not be checked.) If no components were specified, all components in the directory will be checked. Each name-component may contain wild cards.
On success, the UPDATE command returns the number of links that were modified.
UPDATED number LINKS
On failure, the UPDATE command returns the number of links it was unable to update.
FAILED TO UPDATE number LINKS
