You can read the book online here: https://learnbyexample.github.io/learn_gnuawk/

I don't know if it's the best but this resource is good - https://github.com/learnbyexample/learn_gnuawk

I wrote a book for GNU awk one-liners with plenty of examples and exercises. Free to read here: https://learnbyexample.github.io/learn_gnuawk/

Hello!

I am pleased to announce a new version of my "CLI text processing with GNU sed" ebook. This book heavily leans on examples to present features one by one. In addition to sed commands and options, regular expressions are also discussed in detail.

Links:

* PDF/EPUB versions: https://learnbyexample.gumroad.com/l/gnu_sed (free for a few days)

* Web version: https://learnbyexample.github.io/learn_gnused/ (always free)

* 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 :)

Many commands using `-r` do not need the option for the command used (for ex: `sed -r '/start/q'`). Also, using `-E` is preferred instead of `-r` since some of the other implementations support this option but not `-r`.

I wrote a book on GNU sed with plenty of examples and exercises: https://github.com/learnbyexample/learn_gnused It is free to read online and there's a detailed chapter for learning BRE/ERE regex flavor as well.

Good introduction. But they should've at least mentioned that these tools can read a file input directly.

>For example, the sed man page weighs in at around 1,800 words alone without ever really explaining how regular expressions work or the most common uses of sed itself.

For Linux versions, `info` pages for grep/sed/awk are much more detailed and includes examples too. I use `man` pages only for quick reference. Also, I think I've read that BSD man pages are more detailed and include examples compared to Linux versions.

If you'd like to learn more, I have books on these commands with hundreds of examples and exercises (free to read online):

Hello!

This post links to the free to read online version.

PDF/EPUB versions are available from Leanpub/Gumroad [0]. You can either get it as separate book or part of bundles (which includes grep, awk, etc).

Code snippets, markdown source and other files related to the book is available on GitHub [1].

Hope you find it useful. Happy learning :)
