Setting up the scenario:

• User Beyonce has branch "dance"
  • branch dance has most recent commit "move hips" and second most recent commit "stretch"
• User Batman has branch "flying"
  • branch flying has most recent commit "flap arms" and second most recent commit "untangle cape"

Cherry-Pick a Commit

Let's say that you are Batman on your flying branch, and you want to add the code changes that are in the commit "stretch", on Beyonce's dance branch.

1. Checkout Beyonce's dance branch.

2. gitk in terminal

3. Click on the commit you want to cherry-pick, i.e. the one with the comment "stretch"

4. Copy the SHA1 ID (with ctrl-c only)

5. KEEP THE gitk terminal window open!!!

6. In a new terminal window, checkout your own flying branch - i.e. where you want to cherry-pick to.

7. Type git cherry-pick <SHA1 ID>, which you get the from ctrl-shift-v

8. Check out the cherry-pick with gitk to make sure it is correct!

9. You are done! You may close all terminal windows now.
