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.

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).

oxipng, pngquant and svgcleaner for optimizing images

auto-editor for removing silent portions from video recordings

Not my blog, just sharing it here. Saw it on HN (https://news.ycombinator.com/item?id=40419325)

What’s the difference between two_percent and skim?

Yeah, it is uncommon spelling, but if you google, you’ll find it’s not that rare ;)

You’re welcome, happy learning :)

I’m self-published and haven’t worked for other publications. Sometimes, my submissions reach HN front page, so you might have seen there or because others picked it up from there and shared around elsewhere.

As per the manual, “Mappings are set up to work like most click-and-type editors” - which is best suited with GUI Vim.

While Vim doesn’t make sense to use without the modes, there are plugins like https://github.com/tombh/novim-mode!

I had to learn Linux CLI tools, Vim and Perl at my very first job. Have a soft spot for Perl, despite not using it much these days other than occasional one-liners (mainly for advanced regex features).

Thanks a lot for the kind words! Means a lot to me :)

Thanks! 😊

I have a book for Perl One-Liners as well, which I’m currently revising :)

I’ve written books on regex too, if you are interested in learning ;)

Thanks a lot for the feedback on Coreutils book! It’s so nice to hear that it helped in your thesis.

Regarding the ebook versions, I use pandoc to convert GitHub style Markdown to PDF/EPUB (wrote a blog post about my process here: https://learnbyexample.github.io/customizing-pandoc/). I had to search through stackexchange threads to customize the few things I could. I don’t know how to fix the kind of page breaks you mentioned. But, I’ll try to find a solution. Thanks again for the feedback :)

Hope you find the book useful :)
