This example uses istioctl as the formula, but this may come in handy for kubernetes-cli, kubernetes-helm, etc.

1. Find the formula for your executable, e.g. istioctl, and click on the link to GitHub:

   brew info istioctl | grep Formula
   

2. Click "Blame" button ("History" will be too large to display).
3. Hopefully, you can find an earlier versioned commit message... click on it.
4. Click ... in upper-right of next page, select "View File" from drop-down.
5. Right-click "Raw" button, and Copy URL Address.

If you use elasticsearch-curator on AWS (or possibly other hosted or self-hosted Elasticsearch installations that use SSL,) and you get this when curating:

elasticsearch.exceptions.ElasticsearchException: Unable to create client connection to Elasticsearch. Error: Root certificates are missing for certificate validation. Either pass them in using the ca_certs parameter or install certifi to use it automatically.

Then make sure the client.use_ssl key is present and True. This is a non-obvious error that led me down a rathole of Googling. Don't bother specifying root certificates, or installing certifi (it's probably already installed, if you installed elasticsearch-curator with pip.)
