In this article, let us review about awk loop statements – while, do while, for loops, break, continue, and exit statements along [...]

This article is part of the on-going Awk Tutorial Examples series. In our earlier awk articles, we discussed about awk print, awk user-defined variables, awk built-in variables, and awk operators. In this awk tutorial, let us review awk conditional if statements with practical examples. Awk supports lot of conditional statements to control the flow of [...]

In the first article of this series we saw how awk could be put to work (or play) for more than just processing text. The simple script demonstrated the use of associative arrays, recursion and how we could use more arrays (more than required to represent the data) to speed up the processing. There were [...]
