disable interactive prompting

Hi,

Waiting for git-push synchronously slows me down, so I have a bash alias/function to do this in the background. But when my origin is https, I get an undesired interactive prompt. I've tried to disable by redirecting stdin:

git push ${REMOTE} ${BRANCH} &>/dev/null </dev/null

but I still get an interactive prompt.

Is there a way to either

1. disable interactive prompting
2. programmatically determine whether a git command (or at least a git
push) would interactively prompt

Thanks,

Ernesto
