Firstly, the parameter should be either shell=True or shell=False, not shell="True". However, I don't believe that's making any difference here (although shell="False" would act as shell=True, and confuse you greatly). But secondly, you're already splitting the argument (or rather, taking it from your own parameters, already split), so you don't want to go through the shell. In fact, going through the shell would only make your life harder. Change that to shell=False and you'll see everything work. Meta-comment: Rather than attaching your code, please just include it in-line. It's much easier to work with - especially when I want to quote a line and respond to it. Thanks! ChrisA
