[英]Git: how to rebase onto previous commit
I'm working on branch C which is based on branch B, then branch A:我正在处理基于分支 B 的分支 C,然后是分支 A:
A---B---C
Is there any commands that can make branch C directly based on branch A like this:有没有什么命令可以直接基于分支A创建分支C,像这样:
A---B \\ --C
I have tried git rebase A
but it does not work.我试过git rebase A
但它不起作用。
git rebase --onto A B C
Explanation:解释:
In rebase command, you can define:在 rebase 命令中,您可以定义:
and the command is命令是
git rebase --onto TargetBranchToRebaseTo UpstreamBranch BranchToRebase
In fact you can almost an exact example in git help rebase
事实上,你几乎可以在git help rebase
一个确切的例子
Here's what I would do:这是我会做的:
git checkout C
git checkout -b rebaseTemp
git rebase -i A
In the interactive rebase, delete all of the commits that correspond to branch B, but aren't a part of branch C (ie the commits that are shared between the two).在交互式 rebase 中,删除与分支 B 对应但不属于分支 C 的所有提交(即在两者之间共享的提交)。 Complete the rebase, then you will have a new branch (rebaseTemp) that contains what I think you want.完成 rebase,然后您将拥有一个包含我认为您想要的内容的新分支 (rebaseTemp)。 You can then merge A into rebaseTemp (which will result in a fast-forward merge).然后您可以将 A 合并到 rebaseTemp (这将导致快进合并)。
A branch visualization tool (ie gitk
) is really useful for this scenario, so you can see what commits are shared.分支可视化工具(即gitk
)对于这种情况非常有用,因此您可以查看共享的提交。
Git has a builtin option to rebase
that does just that: Git 有一个内置选项来rebase
做到这一点:
git checkout C
git rebase --onto A B
This rebases all of the commits after B up to C such that they start on A instead of B.这会将 B 之后的所有提交重新设置为 C,以便它们从 A 而不是 B 开始。
