@tivasyk thank you for kind words! Reading marketing books made me make this dubious claim. 🤣
But yeah, I agree. I would say that the blog post should've at least talked about #sed -n "${i}p" to use files as arrays in a for loop.
I would say that using #cut to extract data extremely important too.
What would you say should be added there too?
@jonn not sure if you really _need_ to add anything, i like the article as it is.
i think there can be no «complete» list of «must do's», since shell scripting is supposed to be a flexible tool fit for tasks ranging from very simple one-liners to more complex «stage zero» prototyping…
but here's another addition to my «review often» list that you could maybe like:

also, csv with bash could be useful:
