How to Detach a Linux Screen Session

Screen is a powerful tool that allows you to manage multiple terminal sessions within a single window. It is especially useful for remote server administration, as it allows you to detach and reattach sessions at will. In this article, we will discuss how to detach a screen session in Linux.

What is a Screen Session?

A screen session is a virtual terminal that runs in the background on a Linux server. It allows you to run multiple terminal sessions within a single window, which can be useful when working on remote servers or running long-running processes.

Detaching a Screen Session

To detach a screen session, you first need to open a terminal window and start a screen session. You can do this by simply typing the following command:

screen

This will start a new screen session and open a new terminal window. You can now run any commands or processes within this session.

To detach the screen session, you need to press a specific key combination. By default, this key combination is Ctrl + A, followed by d. So, to detach the screen session, you would press Ctrl + A, release the keys, and then press d.

Reattaching a Screen Session

Once you have detached a screen session, it will continue to run in the background. To reattach the session, open a new terminal window and type the following command:

screen -r

This will reattach the most recently detached screen session. If you have multiple detached sessions, you can specify which session to reattach by providing the session ID. You can view a list of all detached sessions by running the following command:

screen -ls

This will display a list of all screen sessions, along with their session IDs. To reattach a specific session, you can use the following command:

screen -r session_id

Replace session_id with the actual ID of the session you want to reattach.

Conclusion

Screen is a powerful tool that allows you to manage multiple terminal sessions within a single window. Detaching and reattaching screen sessions can be extremely useful when working on remote servers or running long-running processes. By following the steps outlined in this article, you should now be able to detach and reattach screen sessions with ease.
