Very Computer

       I have a small problem executing a shell program which
    contains a menu for the users (using ultrix Operating system
    4.2 on MICROVAX II Machine).  I added an option for them to
    logout in the menu using "logout;;" command in the program.
    This command doesn't work and gives me the following
    error message:  "sh: logout not found".

      Even if I include the path for the shell, it still does the
    same thing.  I couldn't find any other command to logout
    in the system, but takes the "exit" or "logout" command
    if typed at the prompt anyhow.

      NOTE:

      One of the systems administrator here suggested, to get the
    process ID # for the shell and do a "kill -9" on that #.

      Is there any easy or better way to do this, other than
    killing the process ID?  Any help will be appreciated.

      Thanks in advance.
