2. Searching for a specific macOS installer
The Apple catalogs maintain multiple versions of the macOS installer. erase-install.sh uses mist, or optionally softwareupdate --list-full-installers, to search for all the installers available. By default it will download the latest version available that is compatible with the hardware on which the script is being run.
If you wish to obtain a different installer, you might want to search the catalog to find the appropriate installer version to download.
To see which versions of the macOS installer app are available, run sudo /path/to/erase-install.sh --list from Terminal. You will see an output something like below:
┌──────────────────┐
│ INPUT VALIDATION │
└──────────────────┘
├─ Search only for latest (first) result will be 'false'...
├─ Include betas in search results will be 'false'...
├─ Only include compatible installers will be 'true'...
├─ Export path will be '/Library/Management/erase-install/mist-list.json'...
├─ Export path file extension is valid...
├─ Output type will be 'ascii'...

Note that no compatibility check is made on the available versions using this method. This is because no Build Version is accessible via this method, so a reliable comparison cannot be made.
When using the --list parameter together with --ffi, you can --seed (or --seedprogram) to search for available versions of the macOS installer app in each seed program. This is commonly used to find beta installers. The available seed programs are PublicSeed, CustomerSeed and DeveloperSeed. These correspond to the Public Beta, AppleSeed and Developer catalogs.
