# Cherry Picking
A cherry-pick takes the patch that was introduced in a commit and tries to reapply it on the branch you’re currently on.
# Copying a commit from one branch to another
git cherry-pick <commit-hash> will apply the changes made in an existing commit to another branch, while recording a new commit. Essentially, you can copy commits from branch to branch.
Given the following tree (Source) (opens new window)
dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master] \ 76cada - 62ecb3 - b886a0 [feature]
Let's say we want to copy
b886a0 to master (on top of
We can run
git checkout master git cherry-pick b886a0
Now our tree will look something like:
dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 - a66b23 [master] \ 76cada - 62ecb3 - b886a0 [feature]
Where the new commit
a66b23 has the same content (source diff, commit message) as
b886a0 (but a different parent). Note that cherry-picking will only pick up changes on that commit(
b886a0 in this case) not all the changes in feature branch (for this you will have to either use rebasing or merging).
# Copying a range of commits from one branch to another
git cherry-pick <commit-A>..<commit-B> will place every commit after A and up to and including B on top of the currently checked-out branch.
git cherry-pick <commit-A>^..<commit-B> will place commit A and every commit up to and including B on top of the currently checked-out branch.
# Checking if a cherry-pick is required
Before you start the cherry-pick process, you can check if the commit you want to cherry-pick already exists in the target branch, in which case you don't have to do anything.
git branch --contains <commit> lists local branches that contain the specified commit.
git branch -r --contains <commit> also includes remote tracking branches in the list.
# Find commits yet to be applied to upstream
git cherry shows the changes which haven't yet been cherry-picked.
git checkout master git cherry development
... and see output a bit like this:
+ 492508acab7b454eee8b805f8ba906056eede0ff - 5ceb5a9077ddb9e78b1e8f24bfc70e674c627949 + b4459544c000f4d51d1ec23f279d9cdb19c1d32b + b6ce3b78e938644a293b2dd2a15b2fecb1b54cd9
The commits that being with
+ will be the ones that haven't yet cherry-picked into
git cherry [-v] [<upstream> [<head> [<limit>]]]
-v Show the commit subjects next to the SHA1s.
< upstream > Upstream branch to search for equivalent commits. Defaults to the upstream branch of HEAD.
< head > Working branch; defaults to HEAD.
< limit > Do not report commits up to (and including) limit.

|-e, --edit||With this option, |
|-x||When recording the commit, append a line that says "(cherry picked from commit …)" to the original commit message in order to indicate which commit this change was cherry-picked from. This is done only for cherry picks without conflicts.|
|--ff||If the current HEAD is the same as the parent of the cherry-pick’ed commit, then a fast forward to this commit will be performed.|
|--continue||Continue the operation in progress using the information in .git/sequencer. Can be used to continue after resolving conflicts in a failed cherry-pick or revert.|
|--quit||Forget about the current operation in progress. Can be used to clear the sequencer state after a failed cherry-pick or revert.|
|--abort||Cancel the operation and return to the pre-sequence state.|
