Unknown options lead to program exiting silently without action

[laurentseal]

Commander version 2.13.0

Calling commander.js with an unknown option or an unknown command leads to the program exiting silently with an exit status of 0.

Ex.
./commanderjsbinary --option1 "argument1" --boolean-option-1 this-command-doesnt-exist cmd "cmdargs"

Note: The following example is minimal, but in bigger projects with existing options it causes the program to exit without warning if for example the user mistypes an argument. This behaviour is certainly unexpected.

A working minimal example:

const program = require('commander');

program.command('existingOption <argument>').description('bla').action(() => {
});

program.parse(process.argv);

A previous issue which might cover your case is #561

This seems to be a duplicate, ok
