How to discard all changes made to a branch?
提问by Will
I'm working in a branch (i.e. design) and I've made a number of changes, but I need to discard them all and reset it to match the repository version. I thought git checkout designwould do it, but it just tells me I'm already in branch designand that I have 3 modified files.
我在一个分支（即design）中工作，并且我进行了一些更改，但是我需要将它们全部丢弃并重置以匹配存储库版本。我以为git checkout design会这样做，但它只是告诉我我已经在分支中design并且我有 3 个修改过的文件。
How would I discard those changes and get the branch as it stands now on the remote server?
我将如何放弃这些更改并获得现在在远程服务器上的分支？

If you don't want anychanges in designand definitely want it to just match a remote's branch, you can also just delete the branch and recreate it:
如果您不希望进行任何更改design并且绝对希望它仅与远程分支匹配，您也可以删除该分支并重新创建它：
# Switch to some branch other than design
$ git br -D design
$ git co -b design origin/design # Will set up design to track origin's design branch

When you want to discard changes in your local branch, you can stash these changes using git stash command.
当您想放弃本地分支中的更改时，您可以使用 git stash 命令隐藏这些更改。
git stash save "some_name"
git stash 保存“some_name”
Your changes will be saved and you can retrieve those later,if you want or you can delete it. After doing this, your branch will not have any uncommitted code and you can pull the latest code from your main branch using git pull.
您的更改将被保存，您可以稍后检索，如果需要，您也可以将其删除。执行此操作后，您的分支将没有任何未提交的代码，您可以使用 git pull 从主分支中提取最新代码。

In the source root:
git reset ./ HEAD <--un-stage any staged changes
git checkout ./ <--discard any unstaged changes
在源根目录中：
git reset ./ HEAD <--un-stage any staged changes
git checkout ./ <--discard any unstaged changes

git checkout -f
git checkout -f
This is suffice for your question. Only thing is, once its done, its done. There is no undo.
这足以回答你的问题。唯一的事情是，一旦完成，它就完成了。没有撤消。
