How to detach a screen on a terminal?

Question

Maybe this is a dumb question. I know how to start a screen or how to list different screens.

screen -ls

or to attached..

There are screens on:
        2477.pts-0.server1      (Detached)
        2522.pts-0.server1      (Detached)
2 Sockets in /var/run/screen/S-root.
screen -r 2477.pts-0.server1

but I keep forgeting how to detach a screen.

Can anyone give me and answer? I want you to show me the exact keys (really don't remember)

This is a good way to have an easy way to keep it simple to search in the future

Answer 1

Ctrl+A followed by D. The [screen manpage] has a long list of these shortcuts under "DEFAULT KEY BINDINGS".

Answer 2

You'll probably see it listed like this in the screen man page:

^a - d

It's important the note the case of the letters as uppercase and lowercase will do different functions.

Answer 3

Some systems remove certain bindings by default. So it is best to look at the online keybinding page: Ctrl-a ?. You can also use the command prompt in screen: Ctrl-a :detach. Myself, I generally remove the key bindings for 'detach' and 'powerdetach', except on remote systems.
