问题
I am trying to find how to reference branch start commit from script. I mean the commit sha at which branch was forked.
Moreover I expect it work for history made from svn repo.
This post just gives first commit of repo creation and not feature branch start commit.
回答1:
What you're looking for is the command merge-base:
git merge-base master feature-branch
will print the best common ancestor of those two branches, i.e. where they forked apart. (The documentation has pretty pretty pictures to clarify some of the interesting cases)
