When I apply the above patch it is getting stuck at app/design/frontend/rwd/default/template/checkout/cart/shipping.phtml at line 120. I have looked at the patch file and the code is
diff --git
app/design/frontend/rwd/default/template/checkout/cart/shipping.phtml

Why is the error appearing?
Edit: Question is asking in the case of identical files.
