After doing some research, I believe the only way you'll be able to use the Tableau Data Extract Command-Line Utility in combination with a batch script is to run some form of an emulator such as Wine, Crossover, or a virtual machine. (4+ Ways to Run Windows Software on Linux)
This probably isn't the answer you were hoping for but I have't been able to find anything else promising.
Good luck and I'd love to hear if you found another method,
