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}

简单解决方案解决方案可行：如果您的HEAD提交与远程提交同步。

在本地工作区中再创建一个分支，并使其与远程分支保持同步。Cherry从新创建的分支上执行的分支（gitcommit--modify）中选择HEAD提交。

精心挑选的提交将只包含最新的更改，而不包含旧的更改。您现在可以重命名此提交。

这晚了将近9年，但没有看到这个变体提到完成相同的事情（这是其中一些的组合，类似于顶级答案(https://stackoverflow.com/a/1459264/4642530).

搜索分支上所有分离的标头

git reflog show origin/BRANCH_NAME--date=相对

然后找到SHA1哈希

重置为旧SHA1

git reset—硬SHA1

然后将其向后推。

git推送原点BRANCH_NAME

完成。

这将使您完全恢复到原来的提交状态。

（包括先前覆盖的分离提交头的日期）

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
