Difference between git branch --set-upstream-to vs git remote add origin
提问by dev02
I find it little confusing to know the difference between git branch --set-upstream-tovs git remote add originor even git remote add upstream
我发现了解git branch --set-upstream-tovsgit remote add origin或 even之间的区别并不令人困惑git remote add upstream
Basically I have a bare repository created with git init --barewhich is shared on network so that other developers could also push to it so that we have our projects versioned locallybut not sure which command should I run amongst above three (or if there is some other) to track that central repo eg we push our changes from all projets to that central bare repo and pull/fetch from it too.
基本上，我创建了git init --bare一个在网络上共享的裸存储库，以便其他开发人员也可以推送到它，以便我们在本地对我们的项目进行版本控制，但不确定我应该在以上三个命令中运行哪个命令（或者如果有其他命令）跟踪中央仓库，例如我们将所有项目的更改推送到中央裸仓库并从中拉取/获取。
Can anyone please enlighten on this?
任何人都可以请教一下吗？

git remote addcreates a remote, which is a shorthand name for another repository. git branch --set-upstream-tosets a branch to be tracked by the branch in the remote repository specified.
git remote add创建一个远程，这是另一个存储库的简写名称。 git branch --set-upstream-to设置要由指定远程存储库中的分支跟踪的分支。
What you are wanting to do is track a remote branch, which is done with git branch --set-upstream-toor more simply git branch -u.
您想要做的是跟踪远程分支，这是使用git branch --set-upstream-to或更简单的方式完成的git branch -u。
when you clone a repository from another, a remote is created named originand the branch masteris checked out. The command to have your local branch master track the remote branch master is git branch -u origin/master, and is executed from the local master branch.
当您从另一个存储库克隆一个存储库时，会创建一个名为的远程存储库origin并master签出该分支。让本地分支 master 跟踪远程分支 master 的命令是git branch -u origin/master，并从本地 master 分支执行。

In order to set the remote tracking branch with set-upstream-to, you need to define a remote repo.
为了使用 设置远程跟踪分支set-upstream-to，您需要定义一个远程仓库。
When your developers are cloning the bare repo, a remote named originis automatically defined for them. I.e, on each local clone, a git remote -vwould list a remote repo named origin, referencing the bare repo. They don't need to define a remote named upstream.
当您的开发人员克隆裸存储库时，origin会自动为他们定义一个远程命名。即，在每个本地克隆上， agit remote -v将列出一个名为 的远程仓库origin，引用裸仓库。他们不需要定义一个名为upstream.
However, that doesn't mean all the branches from that remote are tracked by a local branch.
That is where git branch --set-upstream-tocan come into play.
但是，这并不意味着来自该远程的所有分支都由本地分支跟踪。
这就是git branch --set-upstream-to可以发挥作用的地方。
