It's pretty common for a modern developer to have a database console, web server, and a text editor running at the same time. Switching between these with the mouse takes up valuable time and can break your concentration. By using tmux, you can improve your productivity and regain your focus. This book will show you how. You'll learn how to manage multiple terminal sessions within tmux using only your keyboard. You'll see how to manage and run programs side-by-side in panes, and you'll learn how to create the perfect development environment with custom scripts so that when you're ready to work, your programs are waiting for you.
