I need to use ssh to connect different target boxes using Public and

Is there is any way in ssh where we can check weather the keys are
already set or not.
Generally if the key based authentication fails it will prompt for
*password*. But in my script I don't want SSH to prompt for password,
just it has to return with failure message.

If you're using OpenSSH: ssh -opreferredauthentications=publickey server.
(or if you're using Protocol 1, PasswordAuthentication=no and/or
ChallengeResponseAuthentication=no). The ssh_config(5) man page has
the details.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
