如何从 git 存储库中删除源

Question

基本问题：如何将 git repo 与其克隆的来源解除关联？

git branch -a 显示：

* master
  remotes/origin/HEAD -> origin/master

我想删除所有原始知识以及相关的修订。

更长的问题：我想利用现有的颠覆回购并从中制作一些较小的 git 回购。每个新的 git 存储库都应该只包含相关分支的完整历史记录。我可以使用以下命令将 repo 修剪为所需的子树：

git filter-branch --subdirectory-filter path/to/subtree HEAD

但生成的 repo 仍然包含 origin/master 分支下现在丢弃的子树的所有修订。

我意识到我可以首先使用 git-svn 的 -T 标志来克隆 subversion repo 的相关子树。我不确定这是否比以后在 git repo 的副本上运行多个 git filter-branch --subdirectory-filter 实例更有效，但无论如何，我仍然想断开与源的链接。

Answer 1

相当简单：

git remote rm origin

---

至于filter-branch 问题 - 只需将--prune-empty 添加到您的过滤器分支命令中，它就会删除实际上不包含您生成的存储库中任何更改的任何修订：

git filter-branch --prune-empty --subdirectory-filter path/to/subtree HEAD

Answer 2

删除现有源并将新源添加到您的项目目录

>$ git remote show origin

>$ git remote rm origin

>$ git add .

>$ git commit -m "First commit"

>$ git remote add origin Copied_origin_url

>$ git remote show origin

>$ git push origin master

Answer 3

感谢 mandeep 提供的 git remote show origin 命令。

在我的情况下 git branch -r 将继续在本地存储库上显示 origin/master（在我在远程和本地重命名 master 之后）

这解决了它：

E:\SourceCode\PascalCoinGit\PascalCoin>git remote prune origin
Pruning origin
URL: https://github.com/SkybuckFlying/PascalCoin
 * [pruned] origin/master

E:\SourceCode\PascalCoinGit\PascalCoin>

命令：

git remote show origin

（以前看过但完全忘记了）

结果：

E:\SourceCode\PascalCoinGit\PascalCoin>git remote show origin
* remote origin
  Fetch URL: https://github.com/SkybuckFlying/PascalCoin
  Push  URL: https://github.com/SkybuckFlying/PascalCoin
  HEAD branch: PascalCoinMaster

是的，git branch -r 现在显示它已经消失了！

（我的）案子解决了！ =D
