Hide subcommands unless command is selected?

[synfinatic]

So I have some commands which have many sub-commands. When a user runs exec -h they see a lot of noise because each sub-command is listed. Is there a way to hide the sub-commands for command unless the user does exec command -h?

example showing the ecs command which has many sub-commands I'd like to hide:

It would make sense

There are a whole bunch of options you can use to configure how the help is displayed. Play around and see if anything works for your use case. I typically use HelpOptions{Compact: true}

[alecthomas]

Barring that, you can actually write your own custom help formatter, though that is obviously significantly more work.

Thanks for your feedback. It's indeed interesting.

Your "Read The F ~~u…~~antastic Manual" was very polite. Maybe the kindest one I read for a while. I appreciate.😁
