Show git diff on file in staging area
提问by arod
Is there a way I can see the changes that were made to a fileafter I have done git add file?
有没有办法可以看到file我完成后对 a 所做的更改git add file？
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. I guess there's a way to see the differences since the last commit but I don't know what that is.
没有显示差异。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。

You can show changes that have been staged with the --cachedflag:
您可以显示已使用--cached标志暂存的更改：
$ git diff --cached
In more recent versions of git, you can also use the --stagedflag (--stagedis a synonym for --cached):
在最新版本的 git 中，您还可以使用--staged标志（--staged是 的同义词--cached）：
$ git diff --staged

In order to see the changes that have been staged already, you can pass the -–stagedoption to git diff(in pre-1.6 versions of Git, use –-cached).
为了查看已经暂存的更改，您可以将-–staged选项传递给git diff（在 Git 1.6 之前的版本中，使用–-cached）。
git diff --staged
git diff --cached

You can also use git diff HEAD fileto show the diff for a specific file.
您还可以git diff HEAD file用于显示特定文件的差异。
