Thank you. I actually realized after posting this that my approach was completely wrong. First of all, there is --no-progress which I should have been using. Second, I should have changed the output format to json so that I can use jq to parse instead of awk. I've made those adjustments and I no longer have any issues. Thanks so much for the help!

Some things still don't add up. You said to avoid the untrusted modals I have to sign and notarize it. However, as I stated, I only signed my application and I did not get any untrusted modals. So my questions still apply: Is code signing all I need? If so, in what scenarios is notarization needed? I'd still love to hear from others for a more detailed explanation, or perhaps there's some documentation I can be linked to. The docs I've read so far haven't explained this well enough for me.
