I've been experimenting with a workflow where I only run long-running
processes in tmux. Examples:
tmux (or screen) are good at that: maintaining a long-running process
across shell sessions.
Instead of opening another tmux pane for vim and another for git
commands, Rails generators, test runs, etc., I do all of that outside of
tmux in my normal shell window. Those are all targeted, quick, actions.
They are what I am doing *right now*. It's my workspace.
While experimenting with this process, I noticed, I do jump into tmux
more often. Therefore, I wanted a shorter command for attaching to the
tmux session with the same name as the current directory.
