Between cat, cut, grep, sort, join, uniq, tr, and awk there is so much data processing one can do with text files if only one has: 1. some text files to process, 2. the patience to read through their man and info pages, 3. and a healthy appreciation of unix philosophy. For learning awk at the highest level, the man page will not be enough, and I suggest reading this book: http://www.amazon.com/AWK-Programming-Language-Alfred-Aho/dp/020107981X http://www.amazon.com/AWK-Programming-Language-Alfred-Aho/dp...
