If you want curl to fail on server errors, like non-existing URL's, use
the --fail switch:

Snippet from the man page:

------------------------------
-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.
