也许最简单的方法是用工作副本的当前状态创建一个新的存储库。如果你想保留所有的提交消息，你可以先执行git log > original.log，然后在新的存储库中编辑你的初始提交消息:

rm -rf .git
git init
git add .
git commit

or

git log > original.log
# edit original.log as desired
rm -rf .git
git init
git add .
git commit -F original.log

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

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

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。

最简单的方法是使用'plumbing'命令update-ref删除当前分支。

你不能使用git branch -D，因为它有一个安全阀来阻止你删除当前的分支。

这会让你回到“初始提交”状态，在那里你可以开始一个新的初始提交。

git update-ref -d refs/heads/master
git commit -m "New initial commit"
