使用上次提交签出到临时分支git分支临时HEAD@｛1｝重置上次提交数字复位温度现在，您将拥有您提交的所有文件以及以前提交的文件。检查所有文件的状态。git状态从git阶段重置提交文件。git重置myfile1.js（依此类推）重新附加此提交gitcommit-C HEAD@｛1｝将文件添加并提交到新提交。

您需要做的是创建一个新的提交，其详细信息与当前HEAD提交相同，但父级与先前版本的HEAD相同。gitreset-soft将移动分支指针，以便下一次提交发生在与当前分支头所在位置不同的提交之上。

# Move the current head so that it's pointing at the old commit
# Leave the index intact for redoing the commit.
# HEAD@{1} gives you "the commit that HEAD pointed at before 
# it was moved to where it currently points at". Note that this is
# different from HEAD~1, which gives you "the commit that is the
# parent node of the commit that HEAD is currently pointing to."
git reset --soft HEAD@{1}

# commit the current tree using the commit details of the previous
# HEAD commit. (Note that HEAD@{1} is pointing somewhere different from the
# previous command. It's now pointing at the erroneously amended commit.)
# The -C option takes the given commit and reuses the log message and
# authorship information.
git commit -C HEAD@{1}

也许可以使用git-relog在修改前和修改后获得两个提交。

然后使用git diff before_commit_id after_commit_id>d.diff获取修正前和修正后的差异。

接下来使用git checkout before_commit_id返回提交前

最后使用git-apply.diff应用您所做的真正更改。

这解决了我的问题。

如果您将提交推到远程，然后错误地修改了对该提交的更改，这将解决您的问题。在提交之前发出git日志以查找SHA。（这假设remote被命名为origin）。现在使用SHA发出这些命令。

git reset --soft <SHA BEFORE THE AMMEND>
#you now see all the changes in the commit and the amend undone

#save ALL the changes to the stash
git stash

git pull origin <your-branch> --ff-only
#if you issue git log you can see that you have the commit you didn't want to amend

git stash pop
#git status reveals only the changes you incorrectly amended

#now you can create your new unamended commit

使用ref日志：

git branch fixing-things HEAD@{1}
git reset fixing-things

然后，您应该只在工作副本中保存所有以前修改过的更改，然后可以再次提交

要查看以前索引的完整列表，请键入git-relog
