GIT跨repo查找分支上提交的历史记录

Question

我使用多个存储库(比如repo-1、repo-2、repo-3)，所有的存储库都有共同的分支名称(分支-1、分支-2、分支-3)。有没有办法在‘commit-A’(在repo-1上，分支-1)和'commit-E‘(在repo-3上，分支-1)之间的所有存储库上找到提交到分支-1的历史记录。

你可以在任何git repo中做到这一点。但是，为了保持所有内容的整洁和清晰，让我们在临时回购中进行。

git init temp
cd temp
#If you have already known exactly the sha1 values of commit_A and commit_E, 
#":repo1" and ":repo3" in the following two commands can be omitted.
git fetch <repo1_url> branch_1:repo1
git fetch <repo3_url> branch_1:repo3
#If you haven't, find them out first.

#History between commit-A and commit-E is ambiguous.
#It may have three different meanings:
#1.History of commits that are reachable from commit_A but not reachable from commit_E
git log commit_E..commit_A

#2.History of commits that are reachable from commit_E but not reachable from commit_A
git log commit_A..commit_E

#3.History of commits that are either reachable from commit_A or reachable from commit_E, 
#but not reachable from both at the sam time.
git log commit_A...commit_E
#or
git log commit_E...commit_A

#Finally remove the temporary repo.
cd ..
rm -rf temp
