How can I tell whether I'm in a screen?

Question

When using screen in linux, how can I tell if I\'m in a screen or not? I could do exit and I\'ll exit a screen if I was in one, but if I wasn\'t, then I\'ll end

Answer 1

Alternative approach to check if you are in screen.

type:

Ctrl-a ?

If you see the screen help you are in screen.

Otherwise you'll get a question mark '?' on the prompt.
