exit from unix

Hi All,

How can i exit from "unix"?. Looks silly , but still , i logged in to the unix box , then i did a "su - other user" , then " su - other user" , and i end up in the unix as a some 10th user. If i exist i will come to the previous user/account. I want to exit from unix in a single shot.

Regards

I can only think in one way. killall gnome-terminal

that will close all terminal windows..

I know it's not the same as exit but it's the only thing I can think about

I don't know of a good way to do that. Even if you kill all the terminals you'd still be leaving the login processes out there which would be a mess to clean out. Exiting each of the user shells you logged into is a much better idea so you don't have stranded processes.
