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

一行6个字:

git checkout --orphan new_root_branch  &&  git commit

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.

# edit original.log as desired
rm -rf .git

git commit -F original.log

要做到这一点，你可以将本地git存储库重置为第一个commit标签，这样你在提交后的所有更改都将被取消，然后你可以使用——modify选项提交。

git reset your-first-commit-hashtag
git add .
git commit --amend

然后编辑第一个提交nam如果需要和保存文件。

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。
