After installed emacs on a Ubuntu server, I want to use emacs in tmux style.
First SSH to the Ubuntu server, start a emacs daemon with emacs --daemon,
and attach to it with emacsclient -t.
When I need a break, detach from the emacs with C-x 5 0
(means kill the frame), and logout from the Ubuntu server.
When I want to resume,
SSH to the server and attach to emacs again with emacsclient -t.
Finally when the job is done, stop the emacs daemon with M-x kill-emacs.
