Tips & Notes

Tips and notes for using tmux attach more effectively.

Checking Session List

To check the list of available sessions to attach to, use the 'tmux ls' or 'tmux list-sessions' command.

tmux ls: Displays a list of all currently active tmux sessions. You can see the name and status of each session.
tmux new -s <session-name>: Creates a new session and attaches to it immediately. Naming sessions makes them easier to manage.

How to Detach from a Session

Within a session, press 'Ctrl+b' followed by 'd' to detach from the current session. The session will continue to run in the background.

Importance of Naming Sessions

When using multiple sessions, assigning meaningful names to each session allows you to easily connect to and manage specific sessions using the 'tmux attach -t ' command.
