Show HN: An eBook with hundreds of GNU Awk one-liners Hi, I recently published my ebook on GNU awk one-liners [1]. It starts from the basics of awk syntax and then discusses one-liner examples. There's a chapter on regular expressions as well. The github repo has the details on how to get the PDF version, all the example files and code snippets used in the book, sample chapters as well the markdown source used to generate the PDF. I made all my ebooks [2] free last month amidst the pandemic fears. These include GNU grep & ripgrep, GNU sed and three books on regular expressions (Python, Ruby, JavaScript). I'd appreciate your feedback and hope the books are useful. Happy learning :) [1] https://bit.ly/3dItzBn [2] https://bit.ly/2Jyt0Mt April 2, 2020 at 01:28PM
