Background: Using unix, codeigniter from localhost.

I’d like to run a controllers via a command-line (CLI).
Consequently I’m following this CodeIgniter tutorial and the example works fine.

However when I use it with functions which need to connect to the database, then it appears the following error in the command-line.

Unable to connect to your database server using the provided settings.
Filename: core/Loader.php
Line Number: 347

The strange thing is when I access to the same function via URL it works.
How that’s possible?

Note: The function I pretend to introduce in the command-line is to update the database (it doesn’t print anything).

EDIT:
I’m getting closer.
I’ve changed the hostname from ‘localhost’ to ‘127.0.0.1’ and it works. Why?
