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.

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

Interactive TUI app for exercises: https://github.com/learnbyexample/TUI-apps/blob/main/SedExercises

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 :)

 

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.

Check out my chapter on GNU grep BRE/ERE for those wanting to learn this regex flavor: https://learnbyexample.github.io/learn_gnugrep_ripgrep/breere-regular-expressions.html (there's also another chapter for PCRE)

I use Vim ;)

Python itself provides IDLE, which is good enough for beginners. https://thonny.org/ is another good one for beginners.

As mentioned by others, Jetbrains is good for many languages. https://www.kdevelop.org/ is another option.

I wish you success. I'm happy to use SimpleScreenRecorder(https://github.com/MaartenBaert/ssr).

I'm not the site author, just submitting the link.

Not sure which part you need to be logged in to view - I'm seeing links to different articles and exercises and they are all visible without logging (I checked in an incognito window).

I have a list of learning resources for CLI tools and scripting here: https://learnbyexample.github.io/curated_resources/linux_cli_scripting.html

I've also written a few TUI interactive apps to practice text processing commands like grep, sed, awk, coreutils, etc: https://github.com/learnbyexample/TUI-apps

Why do you think it is a phishing link? Gumroad is a well known platform to sell digital goods.

I mention it is free up to some date because it will go back to being a paid product after that.

I started reading progression fantasy on Royal Road earlier this year (a site for posting web serials). Here's my current follow list (excluding stories that are on hiatus):

  • The Runic Artist — isekai, rune-based crafting, good mix of action and slice-of-life
  • The Broken Knife — Kobold MC with a dragon companion, dark but compelling read, excellent worldbuilding
  • Demon World Boba Shop — cozy isekai, nice characters
  • Dual Wielding — slow burn, tale of two friends (both very talented), writing is good, action scenes get dark and intense
  • Legends and Librarians — cozy romance, magical library (not litrpg/progression), plenty of cute creatures
  • An Otherworldly Scholar — isekai, teacher MC, good worldbuilding, nice romance, great characters, plenty of twists, adventure and danger, especially enjoyed the slice-of-life stuff
  • Archmage from Another World: Gaining Administrator Access — isekai from another fantasy world, lighthearted fun with good set of characters, no looming world-level threats so far
  • Underkeeper — MC is a recent magical academy graduate, good at magic but works as underkeeper (no money/connections to join adventurer groups), got darker than I'm comfortable with, but loved the characters and the demon companion
  • Immovable Mage — good worldbuilding, characters, plot twists and detailed magic system, clever use of plot events pushes MC towards OP, would suggest to read at least till the end of 2nd arc
  • Level One God — likeable MC, cool magic stuff I haven't seen before, some bad moments are really dark, good writing
  • Spire's Spite — criminally underrated with only 100+ followers, mostly been spire climbing so far, good magic system, dark and has some stuff I don't like but overall I've enjoyed it
  • Blood Curse Academia — overall I enjoyed the combination of action, learning and mystery, but a lot of weird coincidences and stuff didn't make sense
  • Mana Mirror — loved the concept of mana garden and the myriad customization options, writing and plot was easy to follow, third volume is the best so far
  • The Maid Is Not Dead — writing felt like traditionally published epic fantasy with progression elements, slow burn but events are starting to escalate
  • Dark Lord's Last Call — MC's soul is swapped with the dark lord, plans to open a tavern, enjoyable light-hearted read
  • Orphan — I usually ignore the litrpg math but this one takes it a bit too far! characters all have flaws (though sometimes it becomes a bit too irritating), good worldbuilding and mystery
  • Rules of Biomancy — 70 year old herbalist MC with a secret past comes across two isekai-ed people in danger of dying and decides to help, enjoying a lot

Not my blog, just sharing it here.

That said, I don't see that broken rectangle on Chromium.

Is it regex or sed/awk syntax (or both) that gives you trouble?

I had similar reaction and didn't even try to learn them for years - then I caught the stackoverflow craze of answering CLI questions (and learning from others).
