If your shell script is called myexit.sh, try calling it like this:
. myexit.sh
rather than just
myexit.sh

Hope this helps.

Hi,

Insert the following statement in your script where you want to exit the system:

kill -9 `ps -fp $PPID|awk '{print $2}'|tail -1`

Hope this helps. Regards.

using 'logout' instead of 'exit' should work too.

Hi,

Actually the following is sufficient in your script:

kill -9 $PPID

PPID (parent process id) is PID (process id) of the login shell (parent) spawning off your shell script (child process)

Hope this helps. Regards.

Only root has rights to do this. How can a user do it?
