The 6th edition of Learning the vi Editor brings the book into the late 1990s. In particular, besides the 'original' version of vi that comes as a standard part of every UNIX system, there are now a number of freely available 'clones,' or work-alike editors. Many of them have improvements over the original vi. One could thus say that there is now a 'family' of vi editors, and this book's goal is to teach you what you need to know to use them.
