I need to use this command every once in awhile and I always forget how to do it off the top of my head.
grep -lr --exclude-dir=".git" -e "oldword" . | xargs sed -i '' -e 's/oldword/newword/g'
If you're on Windows you'll need unix command-line tools installed. The easiest way to do that is with Gow.
Here's what each piece does:
This is a slightly edited response I recently wrote to someone who asked how to learn skills that would be useful at a hackathon. It's my usual response when someone asks how to get started programming.
You should start by approaching the problem from a different perspective. You should be thinking "I want to build X. Now what do I need to learn to build that?" not "I want to learn to build stuff. What can I learn?"
Update, October 2013: I wrote a book, Game Development with Three.js, that goes into much more detail on the concepts discussed in this article and much more about how to build a fuller in-browser game. Check it out if you'd like to learn more!
A lot of people think about programming as some huge, difficult discipline that you sit down and learn like you would learn History or Math. I think I'll learn how to code today, one might say, and I've really been looking forward to that quantum physics class.
Here's the thing: almost no one learns how to code in a classroom, by hearing about it or by reading about it. People learn how to code by doing it, like driving a car. But most people learn how to drive a car because it gets them from Point A to Point B, not because driving is fun. Lots of people drive for fun, but hundreds of millions of people slog through traffic on their way to work every day.
