What is the deal with cut Vs awk?

[BenTheElder]

cut takes a specific delimeter
awk with print like that is reading the args and selecting the nth arg.
if your input is not just say space delimited, but perhaps varying whitespace, they are not equivilant.

I didn't look too deeply at what happened yet, I just tested reverting the entrypoint because it was the smallest and most trivial thing to test of the two suspect changes. Then I looked at the diff and it dawned on me that they are not the same for all inputs so 🙃
