假设我有一个这样的设置
phd/code/
phd/figures/
phd/thesis/
由于历史原因，这些都有自己的git存储库。但是我想把它们合并成一个，这样可以简化一些。例如，现在我可能要做两组更改，并且必须做一些类似的事情
cd phd/code
git commit
cd ../figures
git commit
(现在)只要能表演就好了
cd phd
git commit
似乎有几种方法可以使用子模块或从我的子存储库中提取，但这比我想要的要复杂一些。至少让我满意的
cd phd
git init
git add [[everything that's already in my other repositories]]
但这似乎不是一句俏皮话。git中有什么可以帮助我的吗?

这个bash脚本可以解决sed制表符问题(例如在MacOS上)和丢失文件的问题。
export SUBREPO="subrepo"; # <= your subrepository name here
export TABULATOR=`printf '\t'`;
FILTER='git ls-files -s | sed "s#${TABULATOR}#&${SUBREPO}/#" |
GIT_INDEX_FILE=$GIT_INDEX_FILE.new \
git update-index --index-info &&
if [ -f "$GIT_INDEX_FILE.new" ]; then mv $GIT_INDEX_FILE.new $GIT_INDEX_FILE; else echo "git filter skipped missing file: $GIT_INXEX_FILE.new"; fi'
git filter-branch --index-filter "$FILTER" HEAD
这是迷你夸克，马里乌斯-布图克和瑞恩的哨子的组合。为他们干杯!

借助IntelliJ IDEA Community Edition中的git集成，我手动将3个git存储库合并为一个。
Create a new repo, add a new commit to the master branch with an empty README.md file. Add three remotes for the new repo, using the name of the 3 repositories and the remote URL of them respectively. Run Git Fetch. Create a new local branch named temp based on the master branch, so we can start over without pollute the master branch. Checkout the temp branch. Select to only show commits of one remote branch(one repository). Select all the commits and right click to Cherry-Pick them. Create directory structure for this repository, then move the files into it and commit. Repeat the step 4 to 6 for the other 2 remote branch(repository). When everything is OK, merge all the changes in the temp branch into master branch.
然后添加主分支的原始远程URL并推送到它。
也许，简单地(类似于前面的答案，但使用更简单的命令)在每个单独的旧存储库中进行提交，将内容移动到一个适当命名的子目录中，例如:
$ cd phd/code
$ mkdir code
# This won't work literally, because * would also match the new code/ subdir, but you understand what I mean:
$ git mv * code/
$ git commit -m "preparing the code directory for migration"
然后将三个单独的回购合并为一个新的，通过这样做SMTH:
$ cd ../..
$ mkdir phd.all
$ cd phd.all
$ git init
$ git pull ../phd/code
...
然后您将保存历史记录，但将继续进行单个回购。
你可以尝试子树合并策略。它可以让你将回购B合并到回购A。相对于git-filter-branch的优点是它不需要你重写回购A的历史记录(破坏SHA1和)。
Actually, git-stitch-repo now supports branches and tags, including annotated tags (I found there was a bug which I reported, and it got fixed). What i found useful is with tags. Since tags are attached to commits, and some of the solutions (like Eric Lee's approach) fails to deal with tags. You try to create a branch off an imported tag, and it will undo any git merges/moves and sends you back like the consolidated repository being near identical to the repository that the tag came from. Also, there are issues if you use the same tag across multiple repositories that you 'merged/consolidated'. For example, if you have repo's A ad B, both having tag rel_1.0. You merge repo A and repo B into repo AB. Since rel_1.0 tags are on two different commits (one for A and one for B), which tag will be visible in AB? Either the tag from the imported repo A or from imported repo B, but not both.
git-stitch-repo helps to address that problem by creating rel_1.0-A and rel_1.0-B tags. You may not be able to checkout rel_1.0 tag and expect both, but at least you can see both, and theoretically, you can merge them into a common local branch then create a rel_1.0 tag on that merged branch (assuming you just merge and not change source code). It's better to work with branches, as you can merge like branches from each repo into local branches. (dev-a and dev-b can be merged into a local dev branch which can then be pushed to origin).
我把解也写在这里。它基本上是一个围绕git过滤器分支的相当简单的bash脚本包装器。像其他解决方案一样，它只迁移主分支，而不迁移标签。但是完整的主提交历史被迁移了，它是一个简短的bash脚本，因此用户应该相对容易检查或调整。
