I'm using scp in a script, which normally should always use private key authentication. If for some reason the private key is missing, I want the script to fail rather than display a password prompt.
Is it possible to disable this prompt, or to somehow specify that private key authentication should always be used?
我一直在寻找的选项是-B

-B Selects batch mode (prevents asking for passwords or passphrases).
