Regular Expressions

I just looked it up, you are way off. The regular expression to find an email address (may vary slightly between implementations) is:

NPC Code:

---

\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b

---

In this instance using grep

That technically doesn't match the RFC 2822 specifications for an e-mail address.


Anyways, like I said, 90% of people who use regex don't actually understand what the hell it does or how it works, even if they understand the syntax.

This results in a lot of copying-and-pasting into your codebase from other places, and therefore a lot of potential edge-cases where your script could grind to a halt.
