How to apply a patch generated with git format-patch?

I have two local git repositories, both pointing to the same remote repository.

In one git repository, if I do git format-patch 1, 开发者_如何学JAVAhow can I apply that patch to the other repository?

Note: You can first preview what your patch will do:

First the stats:

git apply --stat a_file.patch

Then a dry run to detect errors:

git apply --check a_file.patch

Finally, you can use git am to apply your patch as a commit. This also allows you to sign off an applied patch.
This can be useful for later reference.

git am --signoff < a_file.patch 

See an example in this article:

In your git log, you’ll find that the commit messages contain a “Signed-off-by” tag. This tag will be read by Github and others to provide useful info about how the commit ended up in the code.

---

git apply name-of-file.patch

---

Or, if you're kicking it old school:

cd /path/to/other/repository
patch -p1 < 0001-whatever.patch

---

First you should take a note about difference between git am and git apply

When you are using git am you usually wanna to apply many patches. Thus should use:

git am *.patch

or just:

git am

Git will find patches automatically and apply them in order ;-)

UPD
Here you can find how to generate such patches

If you want to apply it as a commit, use git am.

If you're using a JetBrains IDE (like IntelliJ IDEA, Android Studio, PyCharm), you can drag the patch file and drop it inside the IDE, and a dialog will appear, showing the patch's content. All you have to do now is to click "Apply patch", and a commit will be created.

Another way is to add one of the local repositories as a remote to another one.

$ cd repo1
$ git remote add repo2 file:///path/to/repo2/.git

So that you can fetch branches, rebase local branches, or cherry-pick commits from one local repo to another.

$ git remote update repo2
$ git fetch repo2 branch:branch-from-repo2
$ git log branch-from-repo2
