I think autocomplete and sub commands can help a lot with discoverability. I don't want to praise the Google Cloud CLI, but one nice thing is you can do something along the lines of $ gcloud <tab> -> list of services you want to manipulate $ gcloud servicename <tab> -> list of action you can do to service $ gcloud servicename actionname --help --> detailed information on how to apply that action It isn't perfect - you don't get this behaviour out-of-the-box with every shell - but it is a lot better than reading a man page with a list of a million flags.
