I have an NFS server running with VCS 1.3. The resources( filesystems) on
this server is shared by many of the clients systems . I need to add another
client system in the resource which can access all the shared filesystem
on the server. Is there anyway I can add the client for all the resources
by one modify command rather than modifying each of the available resource
and adding the client to it.

hares -modify xxx options "%-o rw,ro=new client machine"

where xxx are all the shared resources on the system
