    Set up RSA or DSA authentication keys, and then there's no problem at

    imadev:~$ cp .ssh/ .ssh/authorized_keys
    imadev:~$ ssh vandev ps -fu wooledg | sed 1d
     wooledg 3825 3823 0 09:05:23 ? 0:00 sshd: wooledg@notty
     wooledg 3826 3825 5 09:05:23 ? 0:00 ps -fu wooledg

    That sort of thing. The "log off gracefully" part is a no-op. The ssh
    command's output goes to stdout, so you can pipe it (as shown above),
    save it in a variable, save it to a file, or whatever you need to do.
