Hello!

I recently released a new version of my CLI text processing with GNU sed ebook. This book heavily leans on examples to present features one by one and there are plenty of exercises to help test your understanding of this tool. In addition to sed commands and options, regular expressions are also discussed in detail.

Links:

• Web version: https://learnbyexample.github.io/learn_gnused/ (always free)
• PDF/EPUB: https://learnbyexample.gumroad.com/l/gnu_sed (free for a few days)
• Markdown source, example files, etc: https://github.com/learnbyexample/learn_gnused
• Interactive TUI app for exercises: https://github.com/learnbyexample/TUI-apps/blob/main/SedExercises

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 :)
