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

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

我读过一些关于移植的东西，但从来没有深入研究过。

不管怎样，你可以手动压缩最后2次提交，就像这样:

git reset HEAD~1
git add -A
git commit --amend

我用HEAD^{tree}尝试了不同的命令，但从zsh得到了这个错误:

zsh: no matches found: HEAD^{tree}

这是ohmyzsh处理扩展的方式，查看这个问题了解更多细节: https://github.com/ohmyzsh/ohmyzsh/issues/449

最简单的解决方法是运行这个命令:

unsetopt nomatch

当我从git存储库恢复模板时，我通常会压缩整个树，以获得更干净的历史记录，并确保合法合规。我的工作流程是这样的:

git clone https://git.invalid/my-awesome-template.git my-awesome-foo
cd !$

git branch -M master my-awesome-template/master
git checkout --orphan master
git rm -rf /
git commit --allow-empty --allow-empty-message -m 'Initial commit'
git merge --squash --allow-unrelated-histories my-awesome-template/master
git commit
git branch -D my-awesome-template/master
# you can now `drop' that "Initial commit":
git rebase -i --root

这将把整个历史记录压缩到一个大的提交消息中。

在这个例子中:

Master是工作分支 My-awesome-template /master是一个中间分支

这对我来说效果最好。

git rebase -X ours -i master

这将使git更喜欢你的特性分支;避免艰苦的合并编辑。您的分支需要与主机同步。

ours
           This resolves any number of heads, but the resulting tree of the merge is always that of the current
           branch head, effectively ignoring all changes from all other branches. It is meant to be used to
           supersede old development history of side branches. Note that this is different from the -Xours
           option to the recursive merge strategy.
