Using Spider.php in command Lines

[bazarin]

My apologies for this very simple question, but I need help.
I am using Apache2 and Php4 in a Windows XP environment.
PhpDig is working fine (it's great) for unique URI (using the PhpDig console), but I would like to use it with the command line.
I tryed a lot without success using the Windows shell, and using a Telnet shell.
I used in both cases the command:

C:\Php4>php -f C:\Program Files\Apache Group\Apache2\htdocs\phpdig\admin\spider.php http://www.nga.gov

and received from both the message:

No input file specified.

What am I doing wrong?

Thang you for your help!

Hi:

I could find my error. I included in the Windows XP the path to the php4 directory and PhpDig is working fine now with command line.

Thank you, and I apologies for this dummy question.
