Hello!

I am pleased to announce a new version of my CLI text processing with GNU grep and ripgrep ebook. Examples, exercises, solutions, descriptions and external links were added/updated/corrected. The chapter on ripgrep was changed significantly to focus mostly on the differences compared to GNU grep.

This book will help you learn these commands step-by-step from beginner to advanced levels with hundreds of examples and exercises.
