What does git cherry-pick <commit> do?
HEAD, merging the diff of that commit into it, then fast-forward HEAD." Or in simple words: "Merging a single commit". - anyone Cherry-picking in Git means choosing a commit from one branch and applying it to another.
This contrasts with other ways such as merge and rebase which normally apply many commits to another branch.
It's also possible to cherry-pick multiple commits but merge is the preferred way over cherry-picking.
Make sure you are on the branch you want to apply the commit to.
git switch master
Execute the following:
git cherry-pick <commit-hash>
N.B.:
If you cherry-pick from a public branch, you should consider using
git cherry-pick -x <commit-hash>
This will generate a standardized commit message. This way, you (and your co-workers) can still keep track of the origin of the commit and may avoid merge conflicts in the future.
If you have notes attached to the commit they do not follow the cherry-pick. To bring them over as well, You have to use:
git notes copy <from> <to>

"cherry-pick commit applies the changes introduced by the named commit on the current branch" Most ppl tend to think of commit as changes (like svn was iirc), but it is not, each commit refers to the complete working tree. Though this doesn't make a difference in this case, it can help in understanding why git works like it does. - anyone git cherry-pick command was able to bring over my commit message as well. Are you talking about something else? I didn't need to run git notes command at all to accomplish it. - anyone -x option: 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. git-scm.com/docs/git-cherry-pick - anyone This quote is taken from: Version Control with Git
Using git cherry-pick The command git cherry-pick commit applies the changes introduced by the named commit on the current branch. It will introduce a new, distinct commit. Strictly speaking, using git cherry-pick doesn’t alter the existing history within a repository; instead, it adds to the history. As with other Git operations that introduce changes via the process of applying a diff, you may need to resolve conflicts to fully apply the changes from the given commit . The command git cherry-pick is typically used to introduce particular commits from one branch within a repository onto a different branch. A common use is to forward- or back-port commits from a maintenance branch to a development branch.
$ git checkout rel_2.3
$ git cherry-pick dev~2 # commit F, below

Cherry picking in Git is designed to apply some commit from one branch into another branch. It can be done if you eg. made a mistake and committed a change into wrong branch, but do not want to merge the whole branch. You can just eg. revert the commit and cherry-pick it on another branch.
To use it, you just need git cherry-pick hash, where hash is a commit hash from other branch.

I prepared step-by-step illustrations what cherry-pick does — and an animation of these illustrations (near the end).
L from the branch feature):
git cherry-pick feature~2feature~2 is the 2nd commit beforefeature, i.e. the commit L):
git cherry-pick feature~2):
The same animated:
Note:
The commit L' is from the user's point of view (commit = snapshot) the exact copy of the commit L.
Technically (internally), it's a new, different commit (because e.g. L contains a pointer to K (as its parent), while L' contains a pointer to E).
Answered 2023-09-20 20:18:50
L' is from the user's point of view (commit = snapshot) the exact copy of the commit L.« – No, it's not the same snapshot (unless the snapshots K and E were already the same), just the same difference (i.e. E→L' = K→L). - anyone Short example of situation, when you need cherry pick
Consider following scenario. You have two branches.
a) release1 - This branch is going to your customer, but there are still some bugs to be fixed.
b) master - Classic master branch, where you can for example add functionality for release2.
NOW: You fix something in release1. Of course you need this fix also in master. And that is a typical use-case for cherry picking. So cherry pick in this scenario means that you take a commit from release1 branch and include it into the master branch.
Answered 2023-09-20 20:18:50
release1 is expected to be merged into master later, it might not make sense to cherry-pick (IMHO). You would also want to rebase master1 after having cherry-picked, I guess. - anyone cherry-pick is a Git feature. If someone wants to Commit specific commits in one branch to a target branch, then cherry-pick is used.
git cherry-pick
steps are as below.
git cherry-pick <commit id>
Here commit id is activity id of another branch.Eg.

You can think if a cherry pick as similar to a rebase, or rather it's managed like a rebase. By this, I mean that it takes an existing commit and regenerates it taking, as the starting point, the head of the branch you're currently on.
A rebase takes a commit that had a parent X and regenerates the commit as if it actually had a parent Y, and this is precisely what a cherry-pick does.
Cherry pick is more about how you select the commits. With pull (rebase), git implicitly regenerates your local commits on top of what's pulled to your branch, but with cherry-pick you explicitly choose some commit(s), and implicitly regenerate it (them) on top of your current branch.
So the way you do it differs, but under the hood they are very similar operations - the regeneration of commits.

cherry-pick behaves the way it does when the target branch is later merged back into the source branch. Thank you, sir. - anyone It will apply a particular commit to your current branch.
This means :
Ex: Consider commit A
added newFileA
modified main:
+ import './newFileA'
commit B
added newFileB
modified main:
+ import './newFileB'
If you cherry-pick commit B on another branch, you'll end up with :
/newFileB
/main :
import './newFileA'
import './newFileB'
since commit B contains newFileB and main, but no newFileA, resulting in a bug, so use with caution.

It's kind of like Copy (from somewhere) and Paste (to somewhere), but for specific commits.
If you want to do a hot fix, for example, then you can use the cherry-pick feature.
Do your cherry-pick in a development branch, and merge that commit to a release branch. Likewise, do a cherry-pick from a release branch to master. Voila

When you are working with a team of developers on a project, managing the changes between a number of git branches can become a complex task. Sometimes you don't want to merge a whole branch into another, and only need to pick one or two specific commits. This process is called 'cherry picking'.

If you want to merge without commit ids you can use this command
git cherry-pick master~2 master~0
The above command will merge last three commits of master from 1 to 3
If you want to do this for single commit just remove last option
git cherry-pick master~2
This way you will merge 3rd commit from the end of master.

Here you can perform the cherry pick step by step
Pick only specific commit(s) and raise PR for only those changes:
Step 1: Select those commit hash (Click on commit id and get the complete hash):
https://bitbucket.org/project-name/repo-name/commits/52597fbcc7010e3d4e1ccbdeb5b325331bd3c26
In the above URL, commit hash is: 52597fbcc7010e3d4e1ccbdeb5b325331bd3c26
Step 2: Collect all commit hash that need to have in PR, Suppose, I need 3 commits and its code to have in master and I need raise the PR:
https://bitbucket.org/project-name/repo-name/commits/52597fbcc7010e3d4e1ccbdeb5b32
https://bitbucket.org/project-name/repo-name/commits/ed0e2169ca0f2c69687999977773cc100938185
https://bitbucket.org/project-name/repo-name/commits/5e770f730bacb9ee6e4804b5e66df90b6493139
Step 3: Go to the Repo and run following commands:
git stash
git checkout master
git pull origin master
git checkout -b "my-new-branch"
git cherry-pick 52597fbcc7010e3d4e1ccbdeb5b325331bd3c26
git cherry-pick ed0e2169ca0f2c69687999977773cc100938185
git cherry-pick 5e770f730bacb9ee6e4804b5e66df90b6493139
git push origin my-new-branch
Step 4: Raise the PR against master

Excerpt from the official docs:
Given one or more existing commits, apply the change each one introduces, recording a new commit for each. This requires your working tree to be clean (no modifications from the HEAD commit).
When it is not obvious how to apply a change, the following happens:
The current branch and HEAD pointer stay at the last commit successfully made.
The CHERRY_PICK_HEAD ref is set to point at the commit that introduced the change that is difficult to apply.
Paths in which the change applied cleanly are updated both in the index file and in your working tree.
For conflicting paths, the index file records up to three versions, as described in the "TRUE MERGE" section of git-merge. The working tree files will include a description of the conflict bracketed by the usual conflict markers <<<<<<< and >>>>>>>.
No other modifications are made.
