TMUX is very useful for me to switch between multiple sessions on a node. TMUX is also good for creating a persistent session that we can reattach to when we reconnect later.
Ctrl + b c is creating a session 1
Ctrl + b 0/1 switching between session 0 and session 1
Ctrl d exit the current session
Ctrl + b + [ to enter copy mode, where you scroll up and down to see text outside of your current screen.
Ctrl + b + ] for paste
tmux ls (sees all existing tmux sessions)
Ctrl + b + D (detach without exiting the session)
Ctrl + D (exit the session)
By default, each TMUX session is given a number as name, such as 0,1. As a result, when you try to attach to a specific tmux session, do
tmux attach -t 0/1/2…
But you can also give it a custom name
tmux new -s myname Split Panes on Emacs is also incredibly useful
% vertical split " horizontal split o swap panes q show pane numbers x kill pane + break pane into window (e.g. to select text by mouse to copy) - restore pane from window ⍽ space - toggle between layouts
