Notice how the author had looked up how to do his example in Stack Overflow. I found that foraging through different man pages looking for a specific thing to do only once is just very time consuming. Luckily looking up information on places like Stack Exchange or even different blogs and forums (which I usually land on after using a search engine) is much more efficient. Yes, the information contained might not be completely up-to-date or accurate, but at least it sets you up on the right path to search further.
