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 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.

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. Reader feedback is essential and especially so for self-published authors.

Happy learning :)

Thank you so much for this! I will check it out as soon as I have more time. Up until now I have relied on ChatGPT for my sed needs but I would prefer to learn it myself. Sed always felt pretty complicated to me.

Good professional work!
I've been doing a lot with sed recently and I found some helpful/handy examples in your doc.

I'd forgotten about the use of braces for commanp grouping and put it to use after reading your doc.

Thank you for your work.
