This might be a symptom of a more generic problem: report more clearly if our parameters don't make sense. (Not sure if we should attempt to solve the more generic problem tho. It may only be realistic to solve specific cases, such as the one logged here)

[amishra-dev]

@JohnRusk i am not sure what you mean by this. The thing I want fixed here is that azcopy should not exit without an error/message or some indication to the user about why we exit. This feels like azcopy crashed.

[JohnRusk]

Makes sense. Ignore my earlier comment

The command got treated as a piping scenario, and there was an error with the URL. So an error message should be written to Stderr, since the Stdout is used for content output.

[JohnRusk]

I'd like is to actually introduce a parameter, that must be specified, to invoke pipe mode. It would avoid these kinds of confusing situations, because we could give an error message on input like that described above, if the pipe-mode parameter wasn't set.

(But this would be at the expense of being a breaking change).
