如何使git diff显示与github的pull request diff相同的结果？

问题描述

分支合并后，github不再显示差异，但我尝试提出pull请求，但git diff仍会显示差异。

例如，我有分支D，在分支H上创建了修补程序，将H合并到了D，然后在D上创建了更多的东西。现在，git hub将reuqest从H移动到D显示没有区别，但git diff显示区别。

我试图做的是创建一个命令行工具来查看哪些旧分支（可能有很多）没有代码差异来开发。现在我必须去github，做一个pull reuqest并选择每个分支来查看是否有区别。

谢谢

解决方案

语法：

  git diff D ... H 
  

另见

After branches are merged, and github no longer show difference when i try to make a pull request, but git diff will still show differences.

For example I have branch D, created hotfix on branch H, merged H to D, then created more stuff on D. Now git hub pull reuqest from H to D shows no difference but git diff H D show differences.

What I am trying to do is to create a commandline tool to see which old branches (there can be a lot) don't have code differences to develop. right now I have to go to github, do a pull reuqest and select each branch to see if there are difference.

Thanks

You probably want the "triple-dot" syntax:

git diff D...H
