Problem with Cron Job and WP plugin

I don't know if it's the best category here, but I don't know where else should I have posted it.

So I am using SmartRSS plugin for Wordpress, which fetches RSS feed items and posts them in a Wordpress blog. The file that needs to be run is wp_smartrss.php which is placed in the root of the blog. Specifically to my blog it's found here:

http://myspace.unbanyoutube.info/wp_smartrss.php

The problem is that I set a cron job to run it every 15 minutes, but I get errors for the job. Maybe I'm messing something with the paths.

If I set up this command:
/myspace/wp_smartrss.php
I get this error:

/bin/sh: /myspace/wp_smartrss.php: No such file or directory

PHP:

If I set up this path:
/home/mrgee/public_html/myspace/wp_smartrss.php
I get:

/home/mrgee/public_html/myspace/wp_smartrss.php: line 1: ?php: No such file or directory
/home/mrgee/public_html/myspace/wp_smartrss.php: line 2: /*: No such file or directory
/home/mrgee/public_html/myspace/wp_smartrss.php: line 3: Plugin: command not found
/home/mrgee/public_html/myspace/wp_smartrss.php: line 4: Plugin: command not found

/home/mrgee/public_html/myspace/wp_smartrss.php: line 10: `require_once('wp-config.php');'

PHP:

But if I run the file throug my browser:
http://myspace.unbanyoutube.info/wp_smartrss.php
It works.

What path should I enter to be able to run the cron job correctly?

 

Hi,

suppose it would work with either

wget http://myspace.unbanyoutube.info/wp_smartrss.php

Code (markup):

or, much better:

php /home/mrgee/public_html/myspace/wp_smartrss.php

Code (markup):

Oh, and by the way, thanks for the name of the plugin. Was looking for that recently

 

I will try this now.
PS: It's a great plugin for automated blogs.
