How to apply a patch generated with git format-patch?
GitPatchGit Problem Overview
I have two local git repositories, both pointing to the same remote repository.
In one git repository, if I do git format-patch 1
, how can I apply that patch to the other repository?
Git Solutions
Solution 1 - Git
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.
Solution 2 - Git
git apply name-of-file.patch
Solution 3 - Git
Or, if you're kicking it old school:
cd /path/to/other/repository
patch -p1 < 0001-whatever.patch
Solution 4 - Git
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
Solution 5 - Git
If you want to apply it as a commit, use [git am][git-am].
[git-am]: http://www.kernel.org/pub/software/scm/git/docs/git-am.html "git-am(1) Manual Page - Apply a series of patches from a mailbox"
Solution 6 - Git
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.
