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

我的别名设置在~/。git的Bashrc文件:

alias gdca='git diff --cached' # diff between your staged file and the last commit
alias gdcc='git diff HEAD{,^}' # diff between your latest two commits

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

在比较提交中阅读更多信息

为了比较12345和abcdef作为补丁的两个git提交，可以使用diff命令作为

diff <(git show 123456) <(git show abcdef)

假设您想查看提交012345和abcdef之间的差异。以下内容可以达到你的目的:

$ git checkout 012345
$ git cherry-pick -n abcdef
$ git diff --cached

你可以简单地将2个提交传递给git diff，就像这样:

-> git diff 0da94be  59ff30c > my.patch
-> git apply my.patch
