听起来好像你想要一个远程存储库的镜像:

git clone --mirror url://to/remote.git local.git

该命令创建一个裸存储库。如果您不想要一个裸露的存储库，事情就会变得更加复杂。

如果你正在谈论同步一个分叉回购，那么你可以按照这些步骤。

如何从git同步一个fork存储库

check your current git branch git branch checkout to master if you are not on master git checkout master Fetch the upstream repository if you have correct access rights git fetch upstream If you are getting below error then run git remote add upstream git@github.com:upstream_clone_repo_url/xyz.git fatal: 'upstream/master' does not appear to be a git repository fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. Now run the below command. git fetch upstream Now if you are on master then merge the upstream/master into master branch git merge upstream/master That's it!! Crosscheck via git remote command, more specific git remote -v If I also have commit rights to the upstream repo, I can create a local upstream branch and do work that will go upstream there.

你可以使用git钩子。只需创建一个钩子，在更新后将更改推到另一个回购。

当然，您可能会遇到合并冲突，因此您必须弄清楚如何处理它们。

以下步骤可以做到:

git reset --hard HEAD
git clean -f -x -d -n

然后没有-n

这将处理所有本地更改。现在提交。

git status

注意下面这句话:

Your branch is ahead of 'xxxx' by N commits.

记下数字“N” 现在:

git reset --hard HEAD~N
git pull

最后:

git status

应该没有显示要添加/提交的内容。 所有的清洁。

然而，一个新的克隆也可以做到这一点(但速度要慢得多)。

= = = = = =更新

随着时间的推移，我的git知识略有提高，我想出了另一种更简单的方法来做同样的事情。下面是如何做的(并加以解释)。在你的工作部门:

git fetch # This updates 'remote' portion of local repo. 
git reset --hard origin/<your-working-branch>
# this will sync your local copy with remote content, discarding any committed
# or uncommitted changes.

虽然您的本地提交和更改将在此之后从视野中消失，但如果需要，可以恢复已提交的更改。

重置本地存储库并将其与远程分支同步

命令: 请记住用您想要同步的远程和分支来替换原点和主节点。

git fetch origin && git reset --hard origin/master && git clean -f -d

还是一步一步:

git fetch origin
git reset --hard origin/master
git clean -f -d

您的本地分支现在是远程分支的精确副本(提交和全部)。

命令输出:

下面是在Forge git存储库的本地克隆上运行该命令的示例。

sharkbook:forge lbaxter$ git fetch origin && git reset --hard origin/master && git clean -f -d
HEAD is now at 356cd85 FORGE-680
Removing forge-example-plugin/
Removing plugin-container-api/
Removing plugin-container/
Removing shell/.forge_settings

我也在学习，所以这可能不是问题的确切答案，但它可能会帮助一些人:

When a remote repository is initially cloned copies of all branches are stored in your local repository (view them with git branch -r) To update these copies and make them current (i.e. sync them with the remote branch) use git fetch. This will not effect any of you existing, custom created branches. To override your local branch checkout a fresh version of whatever branch you are working on (Assuming that you have already executed git add origin /path/to/repository) use git checkout origin/branch_name, this will override your locals changes on branch branch_name
