How to Get Out of 'Screen' Without Typing 'Exit'

How do I get out of 'screen' without typing 'exit'?

Ctrl-a d or Ctrl-a Ctrl-d. See the screen manual # Detach.

gnu screen: exit without prompt?

I had originally gotten screen from the standard Ubuntu repo, and apparently, that version of screen makes use of this exit confirmation prompt, while the git version does not. Therefore, I uninstalled screen from the Ubuntu repo and built screen from the code in its git repo: https://git.savannah.gnu.org/git/screen.git . That is version 4.99.0 .

Now, I am not prompted when exiting via C-a \

Kill detached screen session

"kill" will only kill one screen window. To "kill" the complete session, use quit.

Example

$ screen -X -S [session # you want to kill] quit

For dead sessions use:
$ screen -wipe

how can i force screen to detach *instead of* exit/logout?

The main problem isn't screen, it's the shell inside of it. You can make it ignore Ctrl+D or handle it differently. For BASH, try

export IGNOREEOF=4

which means you'll have to press Ctrl+D 4 times to exit the shell.

how to detach an inner screen session

Use ctrl+a, a to send ctrl+a to the inner screen. That is, to detach the inner screen press ctrl+a, a, d. Alternatively press ctrl+a, a, and write :detach.

I also work with the same screen setup as you and found it more convenient to change the ctrl+a shortcut to ctrl+l (lower case "L") on my local machine. That way you can access the inner screen directly with ctrl+a instead of the tedious ctrl+a, a. To do that add this to your local ~/.screenrc:

escape ^La

exit python program without close Tkinter window

control-z doesn't force quit a program. It is more like putting it to sleep, or suspending it. You can cause the program to resume by typing the command fg (foreground) or bg (background).

fg brings it to the foreground, which makes it as if you never typed control-z.

bg places the job in the background and lets it continue running while allowing you to type additional commands in the terminal.

Close console without exit

C++ has no idea of the console. If you need to manipulate the console then you are going to need to use the API for the system you are running on to do that.

To do that on your own you could provide a common interface and then using the preprocessor to conditionally compile the API calls you need to make based on the OS symbols.

How do I force detach Screen from another SSH session?

As Jose answered, screen -d -r should do the trick. This is a combination of two commands, as taken from the man page.

screen -d detaches the already-running screen session, and screen -r reattaches the existing session. By running screen -d -r, you force screen to detach it and then resume the session.

If you use the capital -D -RR, I quote the man page because it's too good to pass up.

Attach here and now. Whatever that means, just do it.

Note: It is always a good idea to check the status of your sessions by means of "screen -list".
