Commander.js: Show help when command is unknown

[0505gonzalez]

Hello,

What would be the best way of printing help output when the command is unknown? E.g. program unknownCommand

[goldcaddy77]

This should work:

    program.on('*', function () {
      console.log('Unknown Command: ' + program.args.join(' '))
      program.help()
    })

It would be good to get this documented in the readme.
