No Unix-class system administrator or user will get far without learning the basics of Vim, the modern replacement for vi, widespread visual text-mode editor. Contrary to some misinformed opinions spread among users who are new to Unix-class systems, Vim is not difficult to learn. Granted, it is not very friendly to beginners, but once you grasp the basic concepts, you will never have to learn another text editor again, because Vim is available for all standard operating systems, including Microsoft Windows, Mac OS X, Linux, BSD, and many others. This book helps you shorten the time you need to spend learning Vim.
