How to use screen
Description
When using telnet or SSH to log in to Linux remotely, if the connection is abnormally interrupted, the system will open a new session when reconnecting, and the original session cannot be restored. The screen command can solve this problem. The Screen tool is a terminal multiplexer. In essence, this means that you can use a single terminal window to run multi-terminal applications. Use screen to establish a tunnel in the background
