Plain dnf with no command, options, or arguments

[hrismarin]

dnf and dnf5 operate differently when running plain dnf with no command, options, or arguments.

In case of dnf (dnf 4) it outputs the version info and the exit code is 0.

In case of dnf5 the output is Missing command. Add "--help" for more information about the arguments. and the exit code is 2. See https://dnf5.readthedocs.io/en/latest/dnf5.8.html#exit-codes.

In the case of dnf5 is it expected (intentional) or an oversight (bug)? If it's the latter, where is the best place to file it?

See osbuild/bootc-image-builder#651

In my opinion, the error is a feature. Why should "dnf5" display its version? Why not e.g. to display a usage help? Or perform a system upgrade instead? Or display nothing and return exit code 0? Current behavior is consistent with tools which require more arguments. E.g. "cp" command from GNU coreutils.

Thanks for the clarification. The issue is resolved in osbuild/bootc-image-builder#658.
