What does git branch -rd remote/branch delete?

Question

git branch -rd remote_name/branch_name
After deletion, the prompt is successful.
Use
git branch -r
to get the remote branch list. There is no branch remote_name/branch. _name,
and then use
git pull
to find that branch branch_name was obtained from the remote end,
then what did
git branch -rd remote_name/branch_name
delete?

My git version is given here:
git version
git version 2.7.0.windows.1

git branch -r 操作的是 remote-tracking branch 这个branch依然是你本地的，不过它不能被编辑。
譬如当你从一个remote上fetch时，如果在此之前其他人在remote上提交了一个新的分支somebranch, you may see the following message:

git fetch origin
remote: Counting objects: 1, done.
remote: Compressing objects: 100% (1/1), done.
remote: Total 1 (delta 0), reused 1 (delta 0)
Unpacking objects: 100% (1/1), done.
[new branch]      somebranch    -> origin/somebranch

At this time, you have one more local branchorigin/somebranchThis is a remote-tracking branch, and then you can checkout one from it to do your work:

git checkout -b sbranch origin/somebranch

Remote branches can only be deleted through git push.
