What is better? Starting with awk or sed?

This is, unless you are running on an embedded environment, but in that case you are stuck with something like busybox's Awk which is way more limited than gawk...
Awk is fine and dandy but, like wity Sed, I think that it's almost always replaceable with Perl which is way nicer to use, and ubiquitous. Every OS (except Windows) I laid my hands on in the last 15 years has had Perl installed in either its default install or pulled in as a dependency almost immediately (a LOT of stuff depends on Perl in any Unix system). This is, unless you are running on an embedded environment, b…
On Windows, you use PowerShell.
I have been using ChatGPT for generating these kind of small CLI like this. My prompts look like this: - use jq to count a nested array "a.b.c.d" - find and delete empty folders using `find` - find and replace text using sed/awk I found that using ChatGPT for these purposes boosted my productivity tremendously.
Just an example, I saw someone come up with a great awk line to change some text in a nested directory. He then pasted into bash. Only once the server went down did anybody realize that he forgot to cd into the proper directory and he wiped out not only the server config but also all the user-uploaded data as well.
The server config was not version controlled and the user data had not been backed up in almost a week.

Soon to be followed by the ones saying nobody should be writing shell scripts at all anymore.

Hello! Author here. I am pleased to announce a new version of my "CLI text processing with GNU awk" ebook. Learn the `GNU awk` command step-by-step from beginner to advanced levels with hundreds of examples and exercises. 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…
I ask because it's the kind of thing that I can imagine finding useful enough to pay $5 (or $15) for, but I can also imagine it being something that contains nothing I don't already have saved in my personal "one liners" file, so I'm not really interested in paying to find out.
