This option will disable URIs getting from command-line.
If '-' is given as < FILE> , URIs will be read from stdin.
URIs are used in this order for each client. All URIs
are used, then first URI is used and then 2nd URI, and
so on. The scheme, host and port in the subsequent
URIs, if present, are ignored. Those in the first URI
are used solely.< / p >
