[tmux] Share a tmux session for pair programming with ssh

By using ssh, you can share a tmux session, making pair programming much easier. We'll learn how to share a tmux session with another user.

 

For one developer:

tmux new-session -s pair

 

For the other developer:

tmux ls  # list all the session
tmux a -t pair # join the pair session

 

Now two developers share the same session.
