一行6个字:

git checkout --orphan new_root_branch  &&  git commit

一个衬套

你可以直接从HEAD创建一个squash-all commit，完全不需要rebase，只需要运行:

git reset $(git commit-tree HEAD^{tree} -m "A new start")

在~/.gitconfig中创建别名

[alias]
  squash-all = "!f(){ git reset $(git commit-tree HEAD^{tree} \"$@\");};f"

然后只要运行:git squash-all -m“一个全新的开始”

注意:要么从标准输入提供提交消息，要么通过-m/-F选项，就像git commit命令一样。参见git-commit-tree手册。

或者，您也可以使用以下命令创建别名:

git config --global alias.squash-all '!f(){ git reset $(git commit-tree HEAD^{tree} "$@");};f'

解释

create a single commit via git commit-tree What git commit-tree HEAD^{tree} -m "A new start" does is: Creates a new commit object based on the provided tree object and emits the new commit object id on stdout. The log message is read from the standard input, unless -m or -F options are given. The expression HEAD^{tree} represents the tree object corresponding to HEAD, namely the tip of your current branch. see Tree-Objects and Commit-Objects. reset the current branch to the new commit Then git reset simply reset the current branch to the newly created commit object. This way, nothing in the workspace is touched, nor there's need for rebase/squash, which makes it really fast. And the time needed is irrelevant to the repository size or history depth.

变体:项目模板中的新回购

这对于在新项目中使用另一个存储库作为模板/原型/种子/框架创建“初始提交”非常有用。例如:

cd my-new-project
git init
git fetch --depth=1 -n https://github.com/toolbear/panda.git
git reset --hard $(git commit-tree FETCH_HEAD^{tree} -m "initial commit")

这避免了将模板回购作为远程(源或其他)添加，并将模板回购的历史记录折叠到初始提交中。

创建备份

git branch backup

重置为指定提交

git reset --soft <#root>

然后将所有文件添加到登台

git add .

提交而不更新消息

git commit --amend --no-edit

推送新分支与压缩提交到回购

git push -f

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

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
