The screen command is helpful to keep terminal sessions running in the background, even after logging out.

Usage

To join an existing screen session or create a new one, use:

screen -R session_name

Delete a Screen Session

To delete a screen session, first list all active sessions with:

screen -ls

Then, to terminate a specific session, use:

screen -X -S session_name quit

• -X: sends a command to the specified screen session
• -S: specifies the session name to target
• quit: command to terminate the session

or alternative method is to reattach to the session and exit from within:

screen -r session_name
exit

This will also close the session properly.

Detach from a Screen Session

To detach from a screen session without terminating it, press:

Ctrl + A, then D

This will leave the session running in the background, allowing you to reattach later.
