Pushing a commit from one repository into another repository

Question

Is it possible for me to push a commit from one Git repository into a branch of another Git repository?

So for example, I have a commit aaaa in Repository A. Commit aaaa is in a branch called "Testing". I want to push commit aaaa into a branch called "Stable" which is in another repository called Repository B. When pushed into Repository B from A, the new commit to Repository B should be an exact image of commit aaaa, ie, replacing all of the files in the branch "Stable" in Repository B with the ones from A.

If this is possible, how can I do it?

Answer 1

Try this:

git push repositoryb aaaa:Stable

I am assuming repositoryb is a remote pointing to the other repo. And if you haven't come to grips with git, the above pushes the commits upto aaaa and not just aaaa.
