在Git中，origin / master vs origin master有什么区别？

问题描述

我知道， origin 是远程存储库的一个术语， master 是分支。

我故意忽略这里的背景，我希望答案不应该取决于背景。所以在git命令行中， origin / master 和 origin master 有什么区别。是否有一种非模糊的方式来了解何时使用 origin / master 以及何时使用原始主人？

origin master 是两件独立的事情， origin / master 是一回事。共有三件事。

两个分支：

master 是一个本地分支

origin / master 是一个远程分支（它是一个远程名为origin的分支名为master的本地副本）

一个远程：

>

• origin 是一个远程

示例：分两步拉

因为 origin / master 是一个分支，你可以合并它。这里有两步：

第一步，从远程原点获取 master 。将获取 origin 上的 master 分支，并将本地副本命名为 origin / master 。

  git fetch origin master 
  

然后，将 origin / master 合并到 master 中。

  git merge origin / master 
  

然后，您可以将 master 中的新更改推回到 origin ：

  git push origin master 
  

更多示例

您可以按名称获取多个分支...

  git fetch origin master stable oldstable 
  

您可以合并多个分支... p>

  git merge origin / master hotfix-2275 hotfix-2276 hotfix-2290 
  

I know, origin is a term for the remote repository and master is the branch there.

I am purposely omitting the "context" here and I am hoping that the answer should not depend upon the context. So in git command lines, what is the difference between origin/master and origin master. Is there a non-ambiguous way to understand when to use origin/master and when I should use origin master?

解决方案

There are actually three things here: origin master is two separate things, and origin/master is one thing. Three things total.

Two branches:

• master is a local branch
• origin/master is a remote branch (which is a local copy of the branch named "master" on the remote named "origin")

One remote:

• origin is a remote

Example: pull in two steps

Since origin/master is a branch, you can merge it. Here's a pull in two steps:

Step one, fetch master from the remote origin. The master branch on origin will be fetched and the local copy will be named origin/master.

git fetch origin master

Then you merge origin/master into master.

git merge origin/master

Then you can push your new changes in master back to origin:

git push origin master

More examples

You can fetch multiple branches by name...

git fetch origin master stable oldstable

You can merge multiple branches...

git merge origin/master hotfix-2275 hotfix-2276 hotfix-2290
