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.

Perl One-Liners Guide with plenty of examples and exercises (learnbyexample.github.io)

submitted 1 year ago by [email protected] to c/[email protected]

Hello!

I am pleased to announce a new version of my Perl One-Liners Guide ebook.

Perl has a feature rich regular expression engine, plenty of builtin modules and a thriving ecosystem. Another advantage is that Perl is more portable. This book will show examples for filtering and substitution features, field processing, using standard and third-party modules, 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.

Links:

PDF/EPUB versions: https://learnbyexample.gumroad.com/l/perl-oneliners or https://leanpub.com/perl-oneliners/c/new_perl_release (free till 07-October-2023)
Web version: https://learnbyexample.github.io/learn_perl_oneliners/
Markdown source, example files, etc: https://github.com/learnbyexample/learn_perl_oneliners

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 :)

This is fantastic! 👏

I use Perl one-liners for record and text processing a lot and this will be definitely something I will keep coming back to - I've already learned a trick from "Context Matching" (9) 🙂
