Thanks a lot for the feedback :)

Well, if you are comfortable with Python scripts, there’s not much reason to switch to awk. Unless perhaps you are equating awk to Python as scripting languages instead of CLI usage (like grep, sed, cut, etc) as my ebook focuses on. For example, if you have space separated columns of data, awk '{print $2}' will give you just the second column (no need to write a script when a simple one-liner will do). This of course also allows you to integrate with shell features (like globs).

As a practical example, I use awk to filter and process particular entries from financial data (which is in csv format). Just a case of easily arriving at a solution in a single line of code (which I then save it for future use).

Not my site, just sharing a link I saw on HN.

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

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.
