using PW api in shell script - "no site configuration or install.php available"

[valan]

I'm trying to do: exactly the same as described here - http://processwire.com/api/include/

I get: "404 page not found (no site configuration or install.php available)"

Q: why?

Note 1: may be it is because of multi-site config in index.config.php? I have read thread below but have not find the answer -

As it usually happens, I found answer myself.)

"*" => mysite

has been commented in index.config.php.

Let me than ask another Q - how to run shell script for non-default site?
