If you understand everything in this article, you should be well on your way to use regex in other environments. Although the syntax may vary slightly in different environments, the principle is the same. Many of the regex information you will be learning here is also transferable. But they are the ones that I find very useful. In fact, I'll be honest right now, that this article probably contains less than a third of what Vim regex can do. This article is by no means a complete regex tutorial. In this article, we will focus on learning and understanding regexes in Vim. You'll unlock more powerful commands using programs like sed, awk, grep, find, vim, and more. Third, it is fun (once you get to a certain proficiency). Many powerful programs (like parsers) are built on top of regexes. Regex allows you to search and modify texts efficiently. Programming is all about creating and updating text. Second, regex is powerful and knowing it can save you a lot of time. Regex knowledge in one domain will transfer everywhere. Sure, there are different regex flavors, but the basic principle is the same across all flavors. To a programmer, regex (regular expression) is a tool.
Many desired to learn them but a few actually did. People who master them are hailed as gods. They are incredibly useful but also hard to read. It is not pleasant but it is good for your soul. Learning regular expressions is like learning latin.
