ABP Suite doesn't have command line interface, basically you use it from its local website. But as it's a local website running in your computer, it is also possible to use it via command line with HTTP requests.
Capture the HTTP request from your browser and save it as PowerShell or cURL command or any other command type. Then use it via command line...
In the screenshot you can see how I add a new solution from the website and how I get the Id of the solution from the response. (All the metadata of the solution comes with the reponse)
I can copy this request as Powershell script:

This is the Powershell script:
Invoke-WebRequest -Uri "http://localhost:20000/api/abpSuite/addSolution" `
-Method "POST" `
-Headers @{
"Accept"="application/json, text/javascript, */*; q=0.01"
"X-Requested-With"="XMLHttpRequest"
"User-Agent"="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.141 Safari/537.36"
"Origin"="http://localhost:20000"
"Sec-Fetch-Site"="same-origin"
"Sec-Fetch-Mode"="cors"
"Sec-Fetch-Dest"="empty"
"Referer"="http://localhost:20000/?solutionId=fb88d059-305a-4960-a888-50a7fe822e18&solution=Mvc.EfCoreTier01153035"
"Accept-Encoding"="gzip, deflate, br"
"Accept-Language"="en-US,en;q=0.9,tr-TR;q=0.8,tr;q=0.7"
"Cookie"="cookieconsent_status=dismiss; .AspNetCore.Antiforgery.aU7BqYCchuM=CfDJ8CGbzqjAwCVHiX1EJkoJOY28ASegiwslrUiaPPgq3PzOOM_NTNwDfpkBfg5z9PfS_ffRh9l5QR-86TysvdERAGuaMOJ9LHtnYEYKiEKWZ404NAHi43-jAWyi0GiOiM3BkLHjBXGYTiLP-DWO2rZFjtA; ActiveSolution=Mvc.EfCoreTier01153035%24fb88d059-305a-4960-a888-50a7fe822e18"
} `
-ContentType "application/json" `
-Body "{`"path`":`"C:\\MyProjects\\4\\4.2.0-preview\\Mvc.EfCoreNonTierPublic01212715`"}"
And I can run this Powershell command to add my solution from command line

With the same steps you can do anything that Suite does, from command line...

@Anthony_Albutt thanks for your detailed feedback. I've created an issue for this. Let the team fix if there's this problem. If it's a bug, probably will be fixed in the next preview version.
Did you add OrLoginWith and AreYouANewUser to the en.json file? If not, add it.

Suite allows you to set a database table name but doesn't allow to change the schema. This should be done manually.
So uncheck the Update database checkbox and modify the generated migration file.
