It's probably worth refactoring this into its own function (something like is_aarch64_setup).

I'll look into that refactoring.

There was one issue I saw with the code that may be due to my ignorance of some bash idioms. When I copied the change into my C:\git-sdk-64\etc\profile.d\git-sdk.sh (where this is installed), I found that I'd get a syntax error at startup, probably due to the way the double quotes and || (or) interact with the # comment.

In the original 257a670 (git-extra: really only add the aarch64 repository for git-sdk-arm64, 2023-02-11) there is only a single opening 'double quote' for the "$(find ...), which looks 'odd' to me - is that (the possible use of the || as an alternate close quote) an idiom I'm not aware of?

If I 'correct' the conditional to either add an echo "here", or a : (colon) just after the || (or), then the error disappears (obvs. fixed in two places).

What am I missing?

No, the reason is that the || should not be here. That's a logical "or" operator, and there is no expression to "or it against". You need to remove it.

That was a bug, hence fixed ("View git blame" can help you find such answers).
