How to log out of su and another user

Question

So when I am logged in as a standard user in an ssh session and then su to root, how can I log out of both accounts with a single command?

Rather than:

root@host:/exit
user@host:/exit

something like:

root@host:/magicallyLogEveryoneOut -bladow

Answer 1

Seeing that any command you type takes more keystrokes I recommend CTRL D , CTRLD, which takes you out of both sessions.

Answer 2

For your exact question about doing this in one command: on one of my RHEL boxes this command works:

fuser -k `tty`

Which SIGKILL's (aka -9) any PID attached to the terminal. Your system's getty program should respawn on its own. I just tried it and it kicked me out of a session where I had sudo'd to root.

I'd be hesitant to do this though, since I run a lot of background jobs and I'd be paranoid that I'd leave one of them running. Also, this is pretty lazy (no offense).

I'd suggest you just have a habit of doing a CTRL-C followed by a bunch of CTRL-D' until the window closes.
