Using awk – Part 2

In this chapter, we’ll continue the discussion about awk, but from a different perspective. In the previous chapter, I showed you the basics of creating one-line awk commands that you can use in your normal shell scripts. In this chapter, I’ll show you a bit about how to write awk scripts in the awk language. Topics in this chapter include:

  • Basic awk script construction
  • Using conditional statements
  • Using a while construct and setting variables
  • Using for loops and arrays
  • Using floating point math and printf
  • Working with multi-line records

If you’re ready, let’s dig in.
