假设你有这些从06年到10年的提交。

您希望将06年后的提交合并为一个提交Id。

commit 10
commit 09  
commit 08  
commit 07  
commit 06

你可以软复位git。

git reset --soft "06"

然后，运行下面的命令将这些更改推送到远程分支。

git push origin HEAD --force

现在，您之前所做的所有提交都应该作为您的本地更改可用，您可以将所有这些提交合并到单个提交中。

现在，新的提交结构应该如下所示:

commit <new_commit_containing_all_7_8_9_10>
commit 06

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。

从git 1.6.2开始，你可以使用git rebase——root -i

对于除第一次提交外的每个提交，将pick更改为squash。

一行6个字:

git checkout --orphan new_root_branch  &&  git commit

echo "message" | git commit-tree HEAD^{tree}

这将创建一个带有HEAD树的孤立提交，并在stdout上输出其名称(SHA-1)。然后重置你的分支。

git reset SHA-1

要在一个步骤中完成上述工作:

git reset $(git commit-tree HEAD^{tree} -m "Initial commit.")

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
