Just a side note: I understand that [1] recommended adding the "$" inside arithmetic expressions, but by chance I happened to be browsing the history of CodingGuidelines and ran across 32b5fe7f0e (CodingGuidelines: drop arithmetic expansion advice to use "$x", 2020-05-04) which dropped[2] the recommendation to use "$" inside the expression. Anyhow, certainly not worth a re-roll. By the way, since you've removed Bashisms, do you still need the `#!/bin/bash` at the top of the script?
