.IP "-f/--fail"
(HTTP) Fail silently (no output at all) on server errors. This is mostly done
like this to better enable scripts etc to better deal with failed attempts. In
-normal cases when a HTTP server fails to deliver a document, it returns a HTML
-document stating so (which often also describes why and more). This flag will
-prevent curl from outputting that and fail silently instead.

If this option is used twice, the second will again disable silent failure.
