This question already has an answer here:
Sometimes I'll start doing something fast. I've got something to do, and I need to get it done now.
Then of course i realize that I need to do something else to help me finish what I started, so I want to add a new shell using tmux (or screen)... but I forgot to start tmux right off....
My question is this:
How can I put a task to the background, start a tmux (or screen) session, and then resume my original task in tmux?
