git撤消所有未提交或未保存的更改 [英] git undo all uncommitted or unsaved changes

问题描述

我试图撤消自上次提交以来发生的所有更改。我在查看后尝试了 git reset --hard 和 git reset --hard HEAD /stackoverflow.com/questions/7999259/git-how-to-perform-the-tfs-equivalent-of-undo-pending-changes\">这篇文章。我现在回复的头是18c3773 ...但是当我看到我的本地源时，所有的文件仍然存在。我错过了什么？

解决方案

• git add ：

    git reset 
   > 




• 这将恢复所有本地未提交的更改（应以repo root身份执行）：
  
  

    git checkout。 
    

  您也可以将未提交的更改仅恢复到特定文件或目录：
  
  

    git checkout [some_dir | file.txt] 
    

  还有另一种方式来恢复所有未提交的更改（更长的输入，但可以从任何子目录中运行）：
  
  

    git reset --hard HEAD 
    




• 这将删除所有本地未跟踪文件， / em> git跟踪的文件仍然存在：

    git clean -fdx 
    

  警告：

总结一下：执行下面的命令基本上等于fresh git clone from original source（但它不会重新下载任何东西，所以速度要快得多）：

  git reset 
 git checkout。 
 git clean -fdx 
  

这个的典型用法是在构建脚本时，必须确保你的树是绝对干净的 - 没有任何修改或本地创建的对象文件或构建工件，并且你想让它工作得非常快，并且不会每次都重新克隆整个存储库。

I'm trying to undo all changes since my last commit. I tried git reset --hard and git reset --hard HEAD after viewing this post. I responds with head is now at 18c3773... but when I look at my local source all the files are still there. What am I missing?

解决方案

• This will unstage all files you might have staged with git add:

  git reset
  

• This will revert all local uncommitted changes (should be executed in repo root):

  git checkout .
  

  You can also revert uncommitted changes only to particular file or directory:

  git checkout [some_dir|file.txt]
  

  Yet another way to revert all uncommitted changes (longer to type, but works from any subdirectory):

  git reset --hard HEAD
  

• This will remove all local untracked files, so only git tracked files remain:

  git clean -fdx
  

  WARNING: -x will also remove all ignored files!

To sum it up: executing commands below is basically equivalent to fresh git clone from original source (but it does not re-download anything, so is much faster):

git reset
git checkout .
git clean -fdx

Typical usage for this would be in build scripts, when you must make sure that your tree is absolutely clean - does not have any modifications or locally created object files or build artefacts, and you want to make it work very fast and to not re-clone whole repository every single time.
