Take care that set -o pipefail will not work on older dash (including IIRC the current Ubuntu LTS), and neither will set -o pipefail || true if set -e is in effect. (For some reason that I’m too lazy to investigate, a failing set invocation will crash the script immediately rather than proceed into the second branch.) The best I could think of to opportunistically enable it was to use a subshell:

  if (set -o pipefail 2>/dev/null); then set -o pipefail; fi

Or you can just target bash, I guess.

(I rather dislike shellcheck because it combines genuine smells with opinions, such as insisting on $(...) instead of `...`. For the same reason, with Python I regularly use pyflakes but can’t stand flake8. But to each their own.)

Only one of those can be (sanely) nested. Why would you ever want to use backticks?

		Looks slick. Works on older shells too
