最好使用git branch -f或git update-ref来快速转发现有分支? [英] Is it better to use git branch -f or git update-ref to fast-forward existing branch?

问题描述

我意识到我可以使用 git update-ref快速转发我不在的现有分支.然后，我发现git branch -f可以完成类似的操作.我知道git update-ref更加灵活(它可以移动任何引用)，无论多么危险.那么使用git branch -f更好吗?在这种特定情况下，这两个命令是否有任何区别? (除此之外，我可以指定自定义引用日志消息.)

I have realized that I can use git update-ref to fast-forward existing branch that I am not on. Then I have found that similar thing can be done by git branch -f. I understand that git update-ref is much more flexible (it can move any ref), however it could be dangerous. So is it better to use git branch -f? Are there any differences in these two commands in this particular scenarios? (Except of that I can specify custom ref log message.)

推荐答案

使用 git branch -f ，如果该分支是已检出的分支，则它将拒绝更新(因此，如果它是当前分支")

With git branch -f, it would refuse to update the branch if it is the one checked out (so if it is the "current branch")

git update-ref 没有该限制.

git update-ref has not that limitation.

Qqwy 添加了另一个区别 如果

git branch -f <branchname> [<start-point>]不存在，它将创建一个名为<branchname>的新分支.

在这种情况下，

git update-ref <branchname> <newvalue>将不执行任何操作.

• git branch -f <branchname> [<start-point>] will create a new branch called <branchname> if it did not exist.
• git update-ref <branchname> <newvalue> will do nothing in this case.
