我写了一个在两次提交之间显示差异的脚本，在Ubuntu上工作得很好。

从Git 2.19开始，你可以简单地使用:

Git range-diff rev1 -比较两个提交树，从它们的共同祖先开始

或 Git range-diff rev1~..rev1 rev2 ~ . . rev2 -比较2个提交所带来的变化

让我来介绍一个简单的GUI/傻瓜证明方法，你可以在这些情况下采取。

克隆另一个副本到新文件夹，例如myRepo_temp 签出您想要与原始回购(myRepo_original)中的提交进行比较的提交/分支。 现在你可以使用不同的工具，(如超越比较等)与这两个文件夹(myRepo_temp和myRepo_original)

这是有用的，例如，如果你想部分逆转一些更改，因为你可以复制东西从一个文件夹到另一个文件夹。

那么这个呢:

git diff abcdef 123456 | less

如果你想要在运行中比较许多不同的差异，将它管道到less是很方便的。

直接在GitHub上查看差异;您可以- https://github.com/<username>/<reponame>/compare/<commit1>..<commit2> .

commit1和commit2可以是分支名或commit哈希值

为例:

比较gs/add-explicit-paths-to-js-files分支和gs/add-history-helper - https://github.com/twbs/bootstrap/compare/gs/add-explicit-paths-to-js-files..gs/add-history-helper 比较commit 75e09b1c0f5ae5f51078c7a25fe36d892c5cfcfe和585146a6a7aa70faf25442d7d28636ce57e29588 - https://github.com/twbs/bootstrap/compare/75e09b1c0f5ae5f51078c7a25fe36d892c5cfcfe..585146a6a7aa70faf25442d7d28636ce57e29588

假设你有这个

A
|
B    A0
|    |
C    D
\   /
  |
 ...

你要确保A等于A0。

这样就可以了:

$ git diff B A > B-A.diff
$ git diff D A0 > D-A0.diff
$ diff B-A.diff D-A0.diff
