[git] Partly cherry-picking a commit with Git

I'm working on 2 different branches: release and development.

I noticed I still need to integrate some changes that were committed to the release branch back into the development branch.

The problem is I don't need all of the commit, only some hunks in certain files, so a simple

git cherry-pick bc66559

does not do the trick.

When I do a

git show bc66559

I can see the diff but don't really know a good way of applying that partially to my current working tree.

If "partly cherry picking" means "within files, choosing some changes but discarding others", it can be done by bringing in git stash:

1. Do the full cherry pick.
2. git reset HEAD^ to convert the entire cherry-picked commit into unstaged working changes.
3. Now git stash save --patch: interactively select unwanted material to stash.
4. Git rolls back the stashed changes from your working copy.
5. git commit
6. Throw away the stash of unwanted changes: git stash drop.

Tip: if you give the stash of unwanted changes a name: git stash save --patch junk then if you forget to do (6) now, later you will recognize the stash for what it is.

Building on Mike Monkiewicz answer you can also specify a single or more files to checkout from the supplied sha1/branch.

git checkout -p bc66559 -- path/to/file.java 

This will allow you to interactively pick the changes you want to have applied to your current version of the file.

If you want to specify a list of files on the command line, and get the whole thing done in a single atomic command, try:

git apply --3way <(git show -- list-of-files)

--3way: If a patch does not apply cleanly, Git will create a merge conflict so you can run git mergetool. Omitting --3way will make Git give up on patches which don't apply cleanly.

Use git format-patch to slice out the part of the commit you care about and git am to apply it to another branch

git format-patch <sha> -- path/to/file
git checkout other-branch
git am *.patch

I know I'm answering an old question, but it looks like there's a new way to do this with interactively checking out:

git checkout -p bc66559

Actually, the best solution for this question is to use checkout commend

git checkout <branch> <path1>,<path2> ..

For example, assume you are in master, you want to the changes from dev1 on project1/Controller/WebController1.java and project1/Service/WebService1.java, you can use this:

git checkout dev1 project1/Controller/WebController1.java project1/Service/WebService1.java

That means the master branch only updates from dev1 on those two paths.

Assuming the changes you want are at the head of the branch you want the changes from, use git checkout

for a single file :

git checkout branch_that_has_the_changes_you_want path/to/file.rb

for multiple files just daisy chain :

git checkout branch_that_has_the_changes_you_want path/to/file.rb path/to/other_file.rb
