git - Git 分支与提交

Question

我有一个主分支到我提交最后一次更改的地方，然后在我运行之后

git branch test
git checkout test

我删除了项目文件夹中的文件README

然后我跑了

git checkout master

现在没有README文件了。

我认为当你创建一个新分支时，就像创建一个新提交一样。我究竟做错了什么？

Answer 1

Creating a branch is not like creating a new commit. Creating a branch is like creating an easy to read reference to a commit hash.

So by being on the master branch and then going:

git branch test
git checkout test
rm README
git checkout master

You will still have unstaged changes on the master branch, because you didn't actually do anything to test.

If you do git status you should have README missing.

You can get it back by doing git checkout README.
