What does cherry-picking a commit with Git mean?

Question

Recently, I have been asked to cherry-pick a commit.

So what does cherry-picking a commit in git mean? How do you do it?

Answer 1

It will apply a particular commit to your current branch.

This means :

• all files added by this commit will be added
• all files deleted by this commit will be deleted
• all files modified by this commit will be merged. This means the whole file from the commit, not only the changes from this commit!

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.
