Git - rollback to a previous commit
提问by Ben Aston
I committed my work (note notpushed) in a known good state. I have since made unwanted local changes (without committing or pushing them). What is the command to undo these changes and revert to my previous commit state?
我以已知的良好状态提交了我的工作（注意不是推送）。从那以后，我进行了不需要的本地更改（没有提交或推送它们）。撤消这些更改并恢复到我以前的提交状态的命令是什么？
Please accept my apologies for the beginner question but the suggestions turned up by my googling seem arcane and I would like to be confident in my actions.
请接受我对初学者问题的道歉，但我的谷歌搜索提出的建议似乎很神秘，我想对自己的行为充满信心。

From Pro Git Commnuity book:
来自Pro Git 社区书籍：
Fixing mistakes
If you've messed up the working tree, but haven't yet committed your mistake, you can return the entire working tree to the last committed state with
$ git reset --hard HEAD
修正错误
如果你搞砸了工作树，但还没有犯你的错误，你可以将整个工作树返回到最后提交的状态
$ git reset --hard HEAD
