Hello!

I am pleased to announce a new version of my CLI text processing with GNU awk ebook. 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.

Book links

To celebrate the new release, you can download the PDF/EPUB versions for free till 06-April-2025.

Or, you can read it online at https://learnbyexample.github.io/learn_gnuawk/

Feedback

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.

Happy learning :)

    I’m not expert in sed or awk. I always have to Google. For me though, it’s generally that you can do a great deal in just one line of awk or sed.

    Same here ! I recently used a one liner awk piped into sed, piped into another command to find duplicated lines and merge both files.

    Writing a python script would have taken an unknown amount of time !
