545598 Google Keyword Script

I need a simple script that will take a list of keywords in csv format and return the number of pages in google for the keyword in quotes. For example: "keyword one" 245,000 results in google. "keyword two" 200,000 results in google. etc, etc. I would like to be able to filter it with 3 or 4 different options. For example, return only those results with less than 300K results, 250K results, 100K results, etc. It does not need to have a developed gui, just something basic for my own use. I would like to be able to run it on my linux VPS.
