How can i get a specific commit changes form other branch?

1. Find the commit hash from test-1:

   git checkout test-1 git log --oneline

   Example output:

   a1b2c3d Commit A d4e5f6g Commit B h7i8j9k Commit C

   Suppose you need only d4e5f6g.

2. Switch to your current branch (test-2):

   git checkout test-2

3. Cherry-pick the commit:

   git cherry-pick d4e5f6g

   This applies the changes from that commit onto test-2.

1. Switch to your target branch

   git switch test-2
   

2. Find the commit hash from the other branch

   git log test-1 --oneline
   

    Copy the required commit hash (e.g. a1b2c3d)

3. Cherry-pick that commit

   git cherry-pick a1b2c3d
   

4. If conflicts occur

   git add .
   git cherry-pick --continue 

 Only that specific commit’s changes from test-1 will be applied to test-2.

you can achieve this by : Temporary Branch + Merge

Use this method when you want to take only one commit from another branch, test it in isolation and then merge it cleanly.

# Switch to the source branch (where the commit exists)
git switch test-1
# Makes sure you're on the branch containing the desired commit.

# Create a temporary branch from that specific commit
git checkout -b temp-pick a1b2c3d
# Creates a new branch "temp-pick" that starts exactly from that commit.

# Switch to your target branch
git switch test-2
# Moves to the branch where you want to apply the commit.

# Merge the temporary branch into the target branch
git merge temp-pick --no-ff -m "Merged commit a1b2c3d from test-1" 
# Applies the isolated commit to test-2 and creates a merge commit for clear history.

# Delete the temporary branch after successful merge
git branch -d temp-pick
# Cleans up the helper branch since it’s no longer needed. 

The specific commit from test-1 is safely merged into test-2, keeping both branches clean, traceable, and easy to revert if needed.
