## Pulling a Subtree from an existing git
|
||
|
|
|
||
|
|
The project has subdirectories `sub-1`, `sub-2`, `sub-3`.
|
||
|
|
The first should be its own repository, but should also retain its own history.
|
||
|
|
|
||
|
|
First, we extract its history as an independent item, and make that into a seprate branch.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
git subtree split --prefix=sub-1 -b sub
|
||
|
|
```
|
||
|
|
|
||
|
|
If you want something a few directories deep, you can use `--prefix=sub-1/dir-2/dir-3
|
||
|
|
|
||
|
|
Then go and create a new git somewhere else:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cd ..;mkdir sub-1;cd sub-1;git init --bare
|
||
|
|
```
|
||
|
|
|
||
|
|
Then go back to your initial git repo, and do the following:
|
||
|
|
|
||
|
|
git push ../subtest sub:master
|
||
|
|
|
||
|
|
Finally, you can clone this repo from your original.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
git clone ../subtest
|
||
|
|
```
|
||
|
