introduction to awk

Awk may sound funny but actually it is an extremely powerful command line tool. Awk or variations of awk (gawk, nawk) can be found on most modern linux & unix distrobutions by default. Awk can be used as a programming language which can nearly turn text files into something more like a database. I am not going to elaborate that extensively on the awk programming language. This article will be addressing many uses for the awk command. Hopefully by the end of this article you will be confident using awk in your day to day command line adventures.I use the awk command for all kinds of things such as trimming down output, restructuring output, & mathmatical computations.
