Answer 1

How to use shift in batch:

:Loop
if "%1"=="" goto End
  use %1 here
shift
goto Loop
:End

Answer 2

Although giving this obvious answer tends to annoy people, it's really not bad advice and totally solves the bash-portability problem: install Cygwin on the TA's machine.

Yes, installing Cygwin is way overkill for many of the little problems posted. But the install is quick, easy, and online, and the installer gets years of small and large problems solved. It seems like a win to me.

My apologies to the Cygwin-suspicious.
