Teach me wget or cURL

I have been reading FAQ's and tutorials but I still can't get what I need. As a hypothetical example, I want to be able to run a .bat file in Windows, that will retreive my Paypal account balance whenever the .bat file is run. After that, I want to be able to provide an email address or ebay item number, and the .bat file will output a file that contains the resulting webpage in paypal (but of course it would be a local file). I think this needs to be done in wget or using [login to view URL] -- but if you have an easier method let me know. I want you to teach me how to do this so I can experiment further on my own. Thus, I need to know which parameters to send and when (i.e. if/why I need to use "send header" "use cookie" etc parameters). This should be a quick project and I gladly reward a good teacher! :) ## Deliverables 1) Basically I would need to have about 15 minutes of interaction via instant message (MSN). I would give you scenario (i.e. above) and you would walk me through it. You may also send me an email of the steps, then I would ask you any questions via instant message. ## Platform Windows XP
