撤消git过滤器分支 [英] Undo git filter-branch

问题描述

使用git filter-branch意外地从我的回购库中删除了一个文件：

  git filter-branch -f --index -filter'git rm --cached --ignore-unmatch images / thumb / a.JPG'HEAD 
  

我该如何解决这个问题？可能吗？也就是文件被永久删除了？

解决方案

当您使用 git filter-branch
$ b

  refs / original / refs / heads / master 
  

如果您在分支 master 中使用了该命令。您可以检查是否在 .git / refs 目录中有备份。考虑到这一点，你可以使用这个备份来恢复你的文件：

  git reset --hard refs / original / refs / heads / master 
  




I accidentally delete a file from my repo using git filter-branch:

git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch images/thumb/a.JPG' HEAD

How can I undo this? Is it possible? i.e. is the file permanently deleted?

解决方案

When you use git filter-branch, a backup file is created in

refs/original/refs/heads/master

If you used the command in branch master. You can check if you have the backup in .git/refs directory. With this in mind, you can use this backup to recover your files with:

git reset --hard refs/original/refs/heads/master
