How to print command helpscreen

[unera]

From time to time I want to show an error and then command helpscreen.

if args.Len() < 3 {
   fmt.Printf("You must choose at least 3 files!\")
   
  // --- the place 
   
   return cli.Exit("some text", 3)
}

How can I print the same screen as prints ./program help or ./program module help?

@unera Depending on whether the command is a root command or is a subcommand you could use one of the following
ShowAppHelpAndExit or ShowSubcommandHelpAndExit
