问题：
Possible Duplicate: 可能重复：
How do I show the changes which have been staged? 如何显示已上演的更改？
Is there a way I can see the changes that were made to a file after I have done git add file ? 有没有办法可以看到我完成git add file后对file所做的更改？
That is, when I do: 也就是说，当我这样做时：
git add file
git diff file
no diff is shown. 没有显示差异。 I guess there's a way to see the differences since the last commit but I don't know what that is. 我想有一种方法可以看到自上次提交以来的差异，但我不知道那是什么。
