git修改分支名称

假设分支名称为oldName
想要修改为 newName

1. 本地分支重命名(还没有推送到远程)

git branch -m oldName newName

2. 远程分支重命名 (已经推送远程-假设本地分支和远程对应分支名称相同)
a. 重命名远程分支对应的本地分支

git branch -m oldName newName

b. 删除远程分支

git push --delete origin oldName

c. 上传新命名的本地分支

git push origin newName

d.把修改后的本地分支与远程分支关联

git branch --set-upstream-to origin/newName

注意：如果本地分支已经关联了远程分支，需要先解除原先的关联关系：

git branch --unset-upstream 

1.修改本地分支名称

git branch -m beforeBranchName afterBranchName

2.删除远程分支

git push origin :beforeBranchName

3.将改名后的本地分支推送到远程，并将本地分支与之关联

git push --set-upstream origin afterBranchName

场景：将分支名称为 oldbranch 改为 newbranch 

步骤：

1、将本地分支oldbranch切一个分支到本地

     git branch -m oldbranch newbranch

 2、删除远程分支

　   git push --delete origin oldbranch

3、将本地新分支推送到远程

　  git push origin newbranch
