Batch mode does not require ssh-agent.

Useful in non-interactive scripts (you don't want a any questions blocking your script).

It also supresses the "host key not found, are you sure you want to continue connecting?" question. (basically fails instead unless some conf variable is set to ignore it).

I assume you're talking about OpenSSH....  (there's no such option in
the 'scp' that comes with SSH-3.1.0)

     -B      Selects batch mode (prevents asking for passwords or passphras-

Yup, seems so.....

I dunno -- have you tried it (I never use ssh-agent in the first place
so I wouldn't know if it's still needed with 'scp -B' or not).
