Summary

In this chapter, we learned about the features which are available in GAWK but not in AWK. We began with features such as handling non-decimal input, two-way inter-process communication, sorting of arrays, network programming and the GAWK built-in command line debugger. Finally, we learned about profiling using GAWK, for optimizing GAWK programs.

In our next chapter, we will cover some use case examples of text-processing using AWK for system administrators and programmers.
