Thanks for the defense, ++ikegami. :-) I was at least ambiguous: in the modern world of Microsoft pushing PowerShell and de-emphasizing (even taking it out of extended context menus) cmd.exe, I need to train myself to be explicit about testing in cmd (though in this case, the cmd vs ps behavior was effectively the same), so I also ++footpad :-). (Besides, my "in windows" mindset is still often muddied by using gnuwin32 ports to make cmd.exe more usable, and I have to be careful to not include that in pure-windows advice without pointing it out. :-) )
edit: And yes, I understand ikegami's main point wasn't just my defense / validating my ego. ;-) I love the back and forth, with the additional information, and corrections when things are incomplete, ambiguous, or downright wrong. I have learned from this thread, and hope the OP has as well. (When I think I can help the OP, or when I want something clarified to help me learn, or both, are my usual times to participate.)
