    do not discard the stderr output so that we can also see what the ssh process reports.

        That means that the remote server doesn't like that key!

        What happens when you run the following command from the command line? 

        ssh -i /export/home/secbatch/.ssh/id_rsa -o PreferredAuthentications=p
+ublickey -v sftp.bloomberg.com

        Check your $PATH in order to ensure you run the same ssh binary as the script and also that you are logged as the same user.
