我如何从git索引获取文件的内容？ [英] How can I get content of a file from git index?

问题描述

我有一个已经添加到我的本地存储库的文件。我在工作树中修改了它，所以 git status 显示我修改的文件。我想知道在执行文件之前，索引中保存了什么文件内容。

我可以想到两种做法那：

1. 恢复 git diff ，并将其应用到工作树中的文件中
   
2. 使用< a href =https://git-scm.com/docs/git-checkout-index =nofollow noreferrer> git checkout-index ，指向一个临时文件并从那里读取内容

是否有更简单的方法？
<使用：前缀来访问当前索引中的对象（暂存但尚未提交）。

  git show：file 
  

有关更多信息，请参阅 gitrevisions手册 。

I have a file which has been already added to my local repository. I've modified it in the working tree, so git status shows me the file as modified. I would like to know what is the file content kept in the index before I stage the file.

I can think of two ways of doing that:

1. revert a patch generated by git diff, and apply it on the file in the working tree
2. use git checkout-index, point to a temporary file and read the content from there

Is there an easier way?

解决方案

Use the : prefix to access objects in the current index (staged but not yet commited).

git show :file

See the gitrevisions manual for more information.
