How to Merge a Specific Commit in Git
Merging a specific commit from one branch into another in Git involves a few steps. This process typically requires using the cherry-pick command, which applies the changes from a specific commit onto your current branch. Here's a detailed guide on how to achieve this:
Steps to Merge a Specific Commit
1. Identify the Commit
First, identify the commit hash that you want to merge. You can find this by listing the commit history on the branch where the commit exists:
- Replace
<branch-name>with the name of the branch containing the commit. - Note the commit hash (a long alphanumeric string) that you want to merge.
2. Checkout the Target Branch
Switch to the branch where you want to apply the commit. This is the branch where the changes will be merged.
- Replace
<target-branch>with the name of the branch where you want to apply the commit.
3. Cherry-Pick the Commit
Use the cherry-pick command to apply the changes from the specific commit onto the current branch.
- Replace
<commit-hash>with the hash of the commit you want to apply.
4. Resolve Conflicts (if any)
If the commit being cherry-picked causes conflicts with the current branch, Git will pause and prompt you to resolve them. To handle conflicts:
- Check the Conflicted Files: Git will indicate which files have conflicts.
- Resolve Conflicts: Edit the conflicted files to resolve the issues.
Stage the Resolved Files:
Continue Cherry-Pick:
If you want to abort the cherry-pick process:
5. Commit the Changes
If the cherry-pick was successful and there were no conflicts, Git will automatically create a new commit on your target branch. If conflicts were resolved, the changes will be committed as part of the cherry-pick process.
6. Push Changes to Remote (if necessary)
After cherry-picking the commit, you may want to push the changes to a remote repository:
- Replace
<target-branch>with the name of your branch.
Example Workflow
Assume you want to cherry-pick a commit from feature-branch into master.
Find the Commit Hash on
feature-branch:Note the commit hash you want to cherry-pick.
Switch to
master:Cherry-Pick the Commit:
Handle Conflicts (if any):
Resolve conflicts, add resolved files, and continue:
Push the Changes:
Summary
To merge a specific commit from one branch to another in Git:
- Find the Commit Hash: Use
git logto get the hash of the commit you want. - Checkout the Target Branch: Switch to the branch where you want the commit applied.
- Cherry-Pick the Commit: Apply the commit with
git cherry-pick <commit-hash>. - Resolve Conflicts: If there are conflicts, resolve them and continue.
- Push Changes: Push the updated branch to the remote repository if needed.
Using cherry-pick allows you to selectively integrate changes from one branch into another without merging the entire branch.
