Description of issue

If I understand correctly, Homebrew binaries are located at /opt/homebrew/bin. Is there a way to get this path programmatically, e.g., maybe Homebrew provide a built-in variable for it?

[SMillerDev]

echo "$(brew --prefix)/bin

Thanks, Sean. I also discovered that I can use $HOMEBREW_PREFIX/bin for it. Is "$(brew --prefix)/bin" a more "correct" solution?

[SMillerDev]

$HOMEBREW_PREFIX/bin only works if those variables are exported somehow. $(brew --prefix)/bin works as long as there is a brew install that is in PATH.
