## Session Management

Sessions are useful for completely separating work environments. I have a ‘Work’ session and a ‘Play’ session; in ‘Work’, I keep everything open that I need during my day-to-day development, while in ‘Play’, I keep open current open-source gems or other work I hack on at home.

	tmux new -s session_name
creates a new tmux session named session_name
	tmux attach -t session_name
attaches to an existing tmux session named session_name
	tmux switch -t session_name
switches to an existing session named session_name
	tmux list-sessions
lists existing tmux sessions
	tmux detach (prefix + d)
detach the currently attached session

## Windows

tmux has a tabbed interface, but it calls its tabs “Windows”. To stay organized, I rename all the windows I use; if I’m hacking on a gem, I’ll name the window that gem’s name. The same thing goes for client applications. That way, I can recognize windows by context and not what application it’s running.

	tmux new-window (prefix + c)
create a new window
	tmux select-window -t :0-9 (prefix + 0-9)
move to the window based on index
	tmux rename-window (prefix + ,)
rename the current window

## Panes

Panes take my development time from bland to awesome. They’re the reason I was able to uninstall MacVim and develop solely in iTerm2. I don’t have to switch applications to switch contexts (editing, reading logs, IRB, etc.) - everything I do, I do in a terminal now. People argue that OS X’s Cmd+Tab is just as fast, but I don’t think so.

	tmux split-window (prefix + ")
splits the window into two vertical panes
	tmux split-window -h (prefix + %)
splits the window into two horizontal panes
	tmux swap-pane -[UDLR] (prefix + { or })
swaps pane with another in the specified direction
	tmux select-pane -[UDLR]
selects the next pane in the specified direction
	tmux select-pane -t :.+
selects the next pane in numerical order
