AWK Programming

AWK text-processing language is useful for such tasks as:

Tallying information from text files and creating reports from the results.

Adding additional functions to text editors like "vi".

Translating files from one format to another.

Creating small databases.

Performing mathematical operations on files of numeric data.

    仔细想想，在编程的过程中，遇到的最多的问题还是字符串，不管是分析字符中、变换字符串，还是别的什么。在LINUX下，有许多处理字符串的语言和工具，比如PERL，SED，AWK等。这次就从AWK开始，毕竟，学习它是很容易的。

    抽出几个小时来学一下吧，这里是一个很好的开始：http://www.vectorsite.net/tsawk.html
