What is Cherry Pick in Git – Guidelines and examples
Today in this article, we will see in detail what is Cherry Pick in Git.
Cherry-pick in Git (Version Control System) is a technique of picking up a commit from a branch and applying it to another branch.
Cherry-pick can address multiple use cases like bug fixing or patching purposes or undoing the changes.
Today in this article, we will cover below aspects,
Cherry-pick concept is common to services like GitHub, Git Lab, or Bit Bucket or using Azure DevOps services which are built on top of Git open-source VCS( Version Control System).
What is Cherry Pick in Git
Cherry-pick in Git (Version Control System) is a technique of picking up a commit from a branch and applying it to another branch.
In Git, you do a cherry-pick for any of the below use cases. This characteristic could be any of the below and not limited to,
- Picking a commit and applying it at the appropriate place typically a branch.
- Bug Fix/Patch on a released branch.
- Undoing the changes previously committed causes issues
- Cherry-pick with the intention of code reuse.
- Collaboration in a team with the intention of code sharing.
- Reverting to the previous best version of code (as it was a good code before someone introduced a bug).
Perform cherry-pick
Performing cherry-pick is a two-step process.
Step 1 – Checkout branch
Check out the Target Branch where cherry-pick needs to be applied. You can reuse the existing branch also if needed. If you check out an existing branch then cherry-pick can be applied the to target branch
git checkout -b R1
Step 2 – Perform cherry-pick
Do a cherry-pick for a given commit hash ID. One can pick a commit ID from any branch to any branch.
So let’s get the relevant commit ID hash.
As we know @7 the code has been checked into git with a commit ID.
So we shall use the same commit hash ID and cherry-pick it as shown below,
The last commit ID is as below from the master branch
Or
you can use the complete commit ID,
git cherry-pick [commit hash-id]
Example
git cherry-pick -x 17784261c69c95649c24c86b52ca35a353e8504e
Cherry Pick in Git – Cherry pick commits from another branch
Cherry pick commits from another branch are similar and you just need to provide the proper commit hash ID with the command.
Command :
git cherry-pick [commit hash-id]
Examples:
git cherry-pick -x 17784261c69c95649c24c86b52ca35a353e8504e
Or
git cherry-pick -x 1778426
Cherry-pick multiple commit ID
Command:
git cherry-pick [commit hash1] [commit hash2] [commit hash3]
Examples:
git cherry-pick 12caab 67qwtr 78tyer
After successful execution, the code based on the above commit ID will be integrated and applied to your existing code base i.e R1 branch.
