Part of the series: Learning Awk

Episodes about using Awk, the text manipulation language. It comes in various forms called awk, nawk, mawk and gawk, but the standard version on Linux is GNU Awk (gawk). It's a programming language optimised for the manipulation of delimited text.

Introduction

This is the fourteenth episode of the “Learning Awk” series which is being produced by b-yeezi and myself.

In this episode and the next I want to start looking at redirection within Awk programs. I had originally intended to cover the subject in one episode, but there is just too much.

So, in the first episode I will be starting with output redirection and then in the next episode will spend some time looking at the getline command used for explicit input, often with redirection.

Long notes

I have provided detailed notes as usual for this episode, and these can be viewed here.
