Awk 是一种非常好的语言，同时有一个非常奇怪的名称。在本系列（共三篇文章）的第一篇文章中，Daniel Robbins 将使您迅速掌握 awk 编程技巧。随着本系列的进展，将讨论更高级的主题，最后将演示一个真正的高级 awk 演示程序。 捍卫 awk (Awk is a very good language, at the same time have a very strange name. In this series (a total of three articles) in the first article, Daniel Robbins will quickly grasp your awk programming skills. With the progress of this series will discuss more advanced subject, and finally will demonstrate a real demonstration of advanced awk program. Defend awk)
