session

tmux has session. this session will be persistent as long as the remote computer is alive. You can completely restore your context-command histroy, current directory, running progrm.

tmux new -s default # new session
tmux ls 

tmux attach -t <session>
tmux> quit # terminate session
tmux> tmux detach # detach current session. session is not terminated

window can be splitted into several panes. tmux can store/restore panes.

prefix + \" : split active pane horizontally
prefix + arrow key : switch to another pane
prefix + o : move to next pane

shortcut
