Actually, the example has way better discoverability than most CLI software, especially if every option had tooltips illustrating what it's for in more detail.

Actually, the example has way better discoverability than most CLI software, especially if every option had tooltips illustrating what it's for in more detail. For an actually good example of adjacent software, have a look at Keystore Explorer: https://keystore-explorer.org/ https://keystore-explorer.org/ I do manage my own CA for some development servers with it, way less of a headache than trying to remember a bunch of arbitrary commands (though obviously not well suited for any sort of automation, which I don't need in that specific use case). For an example of a pleasant CLI with some good discoverability, I've always liked Docker's approach, where the commands are organized in a tree and entering a command without any arguments will print its usage in a useful format: https://docs.docker.com/reference/cli/docker/ https://docs.docker.com/reference/cli/docker/ $>docker Usage: docker [OPTIONS] COMMAND A self-sufficient runtime for containers Common Commands: run Create and run a new container from an image exec Execute a command in a running container ps List containers build Build an image from a Dockerfile pull Download an image from a registry push Upload an image to a registry images List images login Log in to a registry logout Log out from a registry search Search Docker Hub for images version Show the Docker version information info Display system-wide information ...
