如何分离Git中的子目录，但保留所有分支 [英] How to detach subdirectory in Git but keep all branches

问题描述

我一直在关注这个问题的答案将子目录分离为单独的Git存储库

a>，并且有一些很好的成功，只有一个分支上有简单的子目录，但现在我面临的是一个分散在多个分支上的子目录，所以一个简单的

  git filter-branch --subdirectory-filter SUBDIRECTORY HEAD 
  

不做

我是否必须切换到每个分支并运行filter-branch命令，或者是否有可以通过完整历史记录完成空白更改的内容？

解决方案

命令末尾的 HEAD 处理。你可以给它任意数量的其他命令，包括 - all 来指定绝对的一切， - branches 指定只是分支，或 - 遥控器来指定遥控器。您可能必须在 - 前加上这些选项以告诉filter-branch这些是rev-list参数。请注意， - all 会尝试显式处理标签，这可能不是您想要的。您可以使用 - branches --remotes 来指定所有非标记参考。您可能还想添加 - tag-name-filter cat 来重写指向重写提交的标记 - 原始命令将使这些标记保持不变。

I have been following the Answers to this question Detach subdirectory into separate Git repository and had some good successes with simple Subdirectories that are only on one branch but now I am confronted with a Subdirectory that is littered over multiple branches so a simple

git filter-branch --subdirectory-filter SUBDIRECTORY HEAD

does not do the job.

Do I have to switch into each and every branch and run the filter-branch command or is there something that can do a blanked change through the complete history ?

解决方案

The HEAD at the end of your command is specifying the ref to process. You can give it any number of other commands, including --all to specify absolutely everything, --branches to specify just branches, or --remotes to specify just remotes. You may have to prefix these options with -- to tell filter-branch that these are rev-list args. Note that --all will try to process tags explicitly, which may not be what you want. You could use --branches --remotes to specify all non-tag refs instead. You may also want to add --tag-name-filter cat to rewrite tags that point to rewritten commits - your original command will leave those tags unchanged.
