When possible, I like to test for functionality rather than platform. Is there a way to, say, run sed --help and differentiate the Mac version from regular sed?

[ashley-cui]

Sure, sed --help doesn't work on a mac so i can base it off of the exit code for sed --help ?

[edsantiago]

That's really alarming! But yes, I think it would be safe to correlate "sed --help fails" with "this is not GNU sed, therefore it needs a special invocation of -i".

Oops! Forgot to mention: if you edit the PR title, adding [CI:DOCS], you receive a get-out-of-CI-hell-free card. I don't know if you also need to change the subject of your git commit, but if you're going to re-push, might as well.
