Why, oh WHY, do those #?@! nutheads use vi? The VI Gang Sign by Jon Beltran de Heredia, May 16th, 2007 Yes, even if you can't believe it, there are a lot fans of the 30-years-old vi editor (or its more recent, just-15-years-old, best clone & great improvement, vim).
Efficient Editing With vim - Jonathan McPherson. Vim Recipes - Free cookbook for the Vim text editor. Vim Introduction and Tutorial - IMHO. I often tried to learn the great Emacs editor/IDE/operating system.
The last time I tried it, I spent some time getting comfortable with it until I wanted to customize my .emacs file. That was the point when I entered vi .emacs. As soon as I realized what I’ve done, I knew that Vim has won me over a long time ago. So, here I am – using Vim as my editor of choice. Another big motivational boost came after I discovered that my preferred shell (ZSH) has an awesome vi-mode including the command mode (yes, you can switch between command and insert mode!).
