Running Yiiic.php

I am begining the first tutorial from Yii, I have no experience with this framework.

i’m using an IBM I box and i’m running a qshell cmd.

here is the command:

php /www/zendsvr6/htdocs/yii/framework/yiic.php webapp /www/zendsvr6/htdocs/blog

Create a Web application under ‘/www/zendsvr6/htdocs/blog’? (yes|no) [no]:

the problema is how i reply to this?

i have tried y, yes, yes;

and nothing happens.

one question? can I change the default to yes? and if I can How?

thanks in advance!
