He accumulated vast wealth working as a Design Engineer at Analog Devices and retired from the corporate world at the ripe age of twenty-eight. Unfortunately, he squandered his savings within a few years and had to scramble trying to earn a living. Against all odds, selling programming ebooks saved his lazy self from having to look for a job again. He can now afford all the fantasy ebooks he wants to read and spends unhealthy amount of time browsing the internet.<p>When the creative muse strikes, he can be found working on yet another programming ebook (which invariably ends up having at least one example with regular expressions). Researching materials for his ebooks and everyday social media usage drowned his bookmarks, so he maintains curated resource lists for sanity sake. He is thankful for free learning resources and open source tools. His own contributions can be found at <a href=https://github.com/learnbyexample>https://github.com/learnbyexample</a>.<p><strong>List of books:</strong> <a href=https://learnbyexample.github.io/books/>https://learnbyexample.github.io/books/</a><h2 id=license><a class=header href=#license>License</a></h2><p>This work is licensed under a <a href=https://creativecommons.org/licenses/by-nc-sa/4.0/>Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License</a><p>Code snippets are available under <a href=https://github.com/learnbyexample/cli_text_processing_coreutils/blob/main/LICENSE>MIT License</a><p>Resources mentioned in Acknowledgements section above are available under original licenses.<h2 id=book-version><a class=header href=#book-version>Book version</a></h2><p>1.0<p>See <a href=https://github.com/learnbyexample/cli_text_processing_coreutils/blob/main/Version_changes.md>Version_changes.md</a> to track changes across book versions.</main><nav class=nav-wrapper aria-label="Page navigation"><a rel=prev href=buy.html class="mobile-nav-chapters previous"title="Previous chapter"aria-label="Previous chapter"aria-keyshortcuts=Left> <i class="fa fa-angle-left"></i> </a><a rel=next href=introduction.html class="mobile-nav-chapters next"title="Next chapter"aria-label="Next chapter"aria-keyshortcuts=Right> <i class="fa fa-angle-right"></i> </a><div style="clear: both"></div></nav></div></div><nav class=nav-wide-wrapper aria-label="Page navigation"><a rel=prev href=buy.html class="nav-chapters previous"title="Previous chapter"aria-label="Previous chapter"aria-keyshortcuts=Left> <i class="fa fa-angle-left"></i> </a><a rel=next href=introduction.html class="nav-chapters next"title="Next chapter"aria-label="Next chapter"aria-keyshortcuts=Right> <i class="fa fa-angle-right"></i> </a></nav></div><script>
