Usage Examples

Various ways to connect to a screen session.

Reconnect to the most recently detached session

screen -r

If there is only one detached session, it reconnects to that session.

Reconnect using a specific session ID

screen -r 12345

Connects to a specific session using the session ID obtained from the `screen -ls` command.

Reconnect using a specific session name

screen -r my_session_name

Connects using the name specified with the `-S` option when creating the session.

Multi-attach to an already attached session

screen -x

Simultaneously connects to a session that is already attached from another terminal.

Force detach and reconnect a session connected elsewhere

screen -D -r

If the session is already connected, it disconnects the existing connection and connects to the current terminal.

Managing Multiple Sessions

When using multiple screen sessions, assign a unique name to each session (`screen -S my_session`) for easy reconnection using `screen -r my_session`.
