Describe the Feature

I often will run multiple terminal sessions of the same geodesic container. If I ran a terraform command such as terraform apply in sesson[1] and then ran exit in session[0], my session[1] would terminate and leave me with a half applied terraform state.

Use Case

N/A

Describe Ideal Solution

If multiple sessions are open, prompt the user when they try to exit session[0].

$ exit
Detected additional sessions open
* /bin/bash : terraform apply
* etc

Are you sure you want to exit [y/N] ? N

exit prevented

@nitrocode Do you have any suggestion as to how to implement this? You would have to trap/prevent exit, logout, and ctrl-D. I know you can set IGNOREEOF to give a warning on ctrl-D, but I don't know how you would run a custom hook for it.
