我通常是这样做的:

Make sure everything is committed, and write down the latest commit id in case something goes wrong, or create a separate branch as the backup Run git reset --soft `git rev-list --max-parents=0 --abbrev-commit HEAD` to reset your head to the first commit, but leave your index unchanged. All changes since the first commit will now appear ready to be committed. Run git commit --amend -m "initial commit" to amend your commit to the first commit and change the commit message, or if you want to keep the existing commit message, you can run git commit --amend --no-edit Run git push -f to force push your changes

用嫁接压扁

添加一个文件。git/info/grafts，把你想要成为根的提交散列放在那里

Git日志现在将从该提交开始

要让它“真实”运行git filter-branch

这个答案改进了上面的几个(请投票)，假设除了创建一个提交(no-parents - no-history)，你还想保留该提交的所有提交数据:

作者(姓名及邮箱) 撰写日期 提交人(姓名及邮箱) 提交日期 提交日志消息

当然，新的/single提交的commit- sha会改变，因为它代表了一个新的(非)历史，变成了一个无父/根提交。

这可以通过读取git日志并为git提交树设置一些变量来实现。假设你想在一个新的分支one-commit中从master创建一个单独的提交，保留上面的commit-data:

git checkout -b one-commit master ## create new branch to reset
git reset --hard \
$(eval "$(git log master -n1 --format='\
COMMIT_MESSAGE="%B" \
GIT_AUTHOR_NAME="%an" \
GIT_AUTHOR_EMAIL="%ae" \
GIT_AUTHOR_DATE="%ad" \
GIT_COMMITTER_NAME="%cn" \
GIT_COMMITTER_EMAIL="%ce" \
GIT_COMMITTER_DATE="%cd"')" 'git commit-tree master^{tree} <<COMMITMESSAGE
$COMMIT_MESSAGE
COMMITMESSAGE
')

首先，使用git rebase -interactive将所有提交压缩成一个提交。现在就剩下两个壁球提交了。要做到这一点，请阅读任何一本

如何合并Git存储库的前两次提交? Git:如何压缩前两次提交?

我通常是这样做的:

Make sure everything is committed, and write down the latest commit id in case something goes wrong, or create a separate branch as the backup Run git reset --soft `git rev-list --max-parents=0 --abbrev-commit HEAD` to reset your head to the first commit, but leave your index unchanged. All changes since the first commit will now appear ready to be committed. Run git commit --amend -m "initial commit" to amend your commit to the first commit and change the commit message, or if you want to keep the existing commit message, you can run git commit --amend --no-edit Run git push -f to force push your changes

假设你的分支中有3个提交，并且它已经被推送到远程分支。

例子:

git log -4

将显示如下结果:

<your_third_commit_sha>
<your_second_commit_sha>
<your_first_commit_sha>
<master_branch_commit_sha - your branch created from master>

你想把最后3次提交压缩成一次提交，然后推送到远程分支。以下是步骤。

git reset --soft <master_branch_commit_sha>

现在所有提交的更改都被集成但未提交。验证:

git status

用一条消息提交所有更改:

git commit -m 'specify details'

强制将单次提交推到远程分支:

git push -f
