    preventing double logins:

    put this in profile

    [ `who -i |grep -c -w ^$LOGNAME` -gt 1 ] && logout

    This goes for *every user* including you yourself........
    might want to exclude your self by using an if construct...... ;)

    timed log out:
    there is a timed-logout variable for the shell.
    does not log you out if you run another program in that shell ( like vi
    or whatever )

    try the 'w' command and check the output.

    you can script around that info, of course.

    *please note: it is not safe to blindly kill user sessions, they might
    loose data.
    *
    regards Rens

      ... In the 'old' days, when a user typed in a command, the interactive shell would immediately pass it off to 'exec' to execute. ...

As a result of the above, it was hard to tell whether the script was a Bourne shell or C shell, so the convention was introduced of using the Bourne shell no op command, as the first line in a Bourne shell script. ...
