Learn GNU Awk with hundreds of examples and exercises | Aug 2023

Hello! Author here.

I am pleased to announce a new version of my "CLI text processing with GNU awk" ebook.

Learn the `GNU awk` command step-by-step from beginner to advanced levels with hundreds of examples and exercises. This book will dive deep into field processing, show examples for filtering features, multiple file processing, how to construct solutions that depend on multiple records, how to compare records and fields between two or more files, how to identify duplicates while maintaining input order and so on. Regular Expressions will also be discussed in detail.

I would highly appreciate it if you'd let me know how you felt about this book. It could be anything from a simple thank you, pointing out a typo, mistakes in code snippets, which aspects of the book worked for you (or didn't!) and so on. Reader feedback is essential and especially so for self-published authors. Happy learning :)
