How many pages are indexed by google?

How to know for sure...

Hi everyone,

I was wondering if there is a way to know exactly how many pages of my site are spidered by google? What command do you guys use to find this out? The reason I'm asking is because all of the following commands display different results when I type them at google, so which one should I rely on?

site:mysite.com +www.mysite.com
site:mysite.com
site:mysite.com +ExactKeywordThatShouldBeOnEveryPage

I would really appreciate some help on this :)

Not an answer really, and maybe just adding to the confusion.

I only use www.mysite.com on active pages and have always used site:www.mysite.com

This shows a few more pages than just site:mysite.com and loads more than any other of your methods.
