create a script on a windows box that retrieves data from the Linux box by executing cmds

How can i create a script on a windows box that retrieves data from the Linux box by executing cmds against the remote Linux box?

I have got putty and Plink on the win box but not sure how to fire the cmds from a script eg a bat file and get the results written back to a txt file on the win box.

Any ideas how i would do this for something simple like a grep or LS cmd for example?
