> Could be an interesting topic however this article feels very AI generated. It’s just questions and straight up answers without additional insight. Just like a ChatGPT thread. Very disappointing.

> Not good content. I found an error in the article with question 16. I'm sure there are more and many of the answers feel like they could be improved upon a lot:

> >[[ $string == “efg*” ]] > checks if string is efg)

> Question number 17. Isn't a question. Question 14. is a repitition of question number 1.  These are just the most obvious issues I saw in the article. I'm sure there are more.
