REmux The Tmux
ssh
tux:tmuxwithremux
Starting tmux "Sessions" and default tmux "prefix"
The first session create will have the name "0". By default, tmux status bar will be green. With session name on the left. Windows in the middle and window names in the middle. Hostname, time, and date on the right of the bottom green bar.
Tmux doesn't allow to create of a nested tmux within a tmux unless you force it to.
To change the session name from "0" -> "box-dev". Must first learn how tmux is called. All commands within a tmux session all start with the tmux prefix is. By default, the tmux prefix is "Ctrl b".
After the tmux prefix. To the hotkeys to change the current tmux session's name is "shift $". ctrl b shift $ Retype the new name and then enter-key to save the new session name.
If there is a need to create another tmux session within the current one. Use the -d argument with the tmux command. To spawn a new tmux session without attaching to it. In the example image below. The -s argument is used to specify the session name for the new session.
To list all active tmux sessions.
Exiting a tmux session without closing it can be done with the prefix. Followed by d ctrl b d Checking again with the tmux ls command. "(attached)" is missing from both sessions. This means the sessions are active but we are detached and are unable to interact with either session.
To reattach to an active tmux session. Run tmux with the attach option and -t followed by the desired session name.
Delete a single session by its session name. Is done with the kill-session option with tmux. Followed by -t and the target-session-name-to-delete

ctrl b shift #
==Note. Even though the text might look broken don't worry it will paste as it was copied within a terminal file editor. To quit back to the terminal. Hit the q key once.==
