Summary

In this chapter, I introduced you to the sacred mysteries of using awk. We started by looking at the numerous implementations of awk, and at how a basic awk command is constructed. Next, we saw how to use awk to process information either from a text file or from another program. Then, we saw how to run awk commands from within a normal shell script. Finally, we turned an awk command into a function, and added it to our function library file.

In the next chapter, we’ll look at how to create awk program scripts. I’ll see you there.
