Well, I’m not going to even try understanding the various features used in that sed command. I do know how to use basic loops with labels, but I never bothered with all the buffer manipulation stuff. I’d rather use awk/perl/python for those cases.

This might work, but I think it is best to not tinker further if you already have a working script (especially one that you understand and can modify further if needed).

perl -pe 's/\[[^]]+\]\((?!https?)[^#]*#\K[^)]+(?=\))/lc $&=~s:%20|\d\K\.(?=\d):-:gr/ge'

Hmm, OP mentioned “Only edit what’s between parentheses” - don’t see anywhere that whole URL shouldn’t be changed…

Here’s a solution with perl (assuming you don’t want to change http/https after the start of ( instead of start of a line):

perl -pe 's/\[[^]]+\]\(\K(?!https?)[^)]+(?=\))/lc $&=~s|%20|-|gr/ge' ip.txt

• e flag allows you to use Perl code in the substitution portion.
• \[[^]]+\]\(\K match square brackets and use \K to mark the start of matching portion (text before that won’t be part of $&)
• (?!https?) don’t match if http or https is found
• [^)]+(?=\)) match non ) characters and assert that ) is present after those characters
• $&=~s|%20|-|gr change %20 to - for the matching portion found, the r flag is used to return the modified string instead of change $& itself
• lc is a function to change text to lowercase

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’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

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).
