我有两个 git 存储库，我想将它们合并在一起而不丢失它们的提交历史。我试过这个：
cd firstRepo
git remote add other path/to/otherRepo
git fetch other
git checkout -b otherRepoBranch other/master
echo "`git rev-list otherRepoBranch | tail -n 1` `git rev-list master | head -n 1`" >> .git/info/grafts
git rebase otherRepoBranch master
现在，当我查看提交历史记录时，一切看起来都不错，但我的存储库中的唯一文件现在是 otherRepo 中的文件。
有什么想法吗？

我知道这已经很晚了，但是对于仍在寻找方法的人来说，我在这里收集了很多关于 StackOverFlow 等的信息，并设法将一个脚本放在一起，为我解决了这个问题。
脚本实际上甚至处理功能分支和标签 - 在新项目中重命名它们，以便您知道它们来自哪里。

## Script to merge multiple git repositories into a new repository
## - The new repository will contain a folder for every merged repository
## - The script adds remotes for every project and then merges in every branch
## and tag. These are renamed to have the origin project name as a prefix
##
## Usage: mergeGitRepositories.sh <new_project> <my_repo_urls.lst>
## - where <new_project> is the name of the new project to create
## - and <my_repo_urls.lst> is a file contaning the URLs to the respositories
## which are to be merged on separate lines.

您也可以从http://paste.ubuntu.com/11732805/获取它
首先创建一个包含每个存储库的 URL 的文件，例如：
git@github.com:eitchnet/ch.eitchnet.parent.git
git@github.com:eitchnet/ch.eitchnet.utils.git
git@github.com:eitchnet/ch.eitchnet.privilege.git
然后调用脚本，给出项目名称和脚本路径：
./mergeGitRepositories.sh eitchnet_test eitchnet.lst
脚本本身有很多 cmets 应该解释它的作用。
已编辑以将脚本替换为更高级的脚本。
【讨论】：
在最简单的情况下，您希望合并后来自两个存储库的所有文件，您应该能够简单地使用 git merge：
cd firstRepo
git remote add other path/to/otherRepo
git fetch other
git checkout -b merged
git merge --allow-unrelated-histories other/master
【讨论】：
这篇权威文章讨论了开头段落中的简单案例 - 并将更有可能的案例作为其主要主题：How to use the subtree merge strategy
保留两个存储库的提交历史记录。
这是我的版本——基于上面引用的文章...
git remote add temp staging_path/(reponame)
git fetch temp
git fetch --tags temp ## optional -- may pull in additional history
for remote in $(git branch -r | grep temp/ ) ; do git branch --no-track imported_$(basename $remote) $remote ; done ## create local branches prefixed with 'imported_'
git remote rm temp ## optional -- assumes you no longer plan to use the source repo
git merge -s ours --no-commit imported_master ## mysterious "merge strategy"
git read-tree -u --prefix=(reponame)/ imported_master ## move to sub-folder
git commit
【讨论】：
git merge命令中添加--allow-unrelated-histories：stackoverflow.com/a/37938036/376366
我认为 git 存储库不相关？就像它们是您想要合并在一起以形成组合存储库的单独项目的不同存储库一样？如果是这样，那么以下参考资料可能会有所帮助：
