From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hello!

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.

PDF/EPUB versions: https://learnbyexample.gumroad.com/l/gnu_awk (free till 31-August-2023)
Web version: https://learnbyexample.github.io/learn_gnuawk/
Markdown source, example files, etc: https://github.com/learnbyexample/learn_gnuawk
Interactive TUI app for exercises: https://github.com/learnbyexample/TUI-apps/blob/main/AwkExercises

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 :)
