Commit to multiple branches at the same time with git
You could:
- make all your commits on
A - rebase
Bon top ofA(if you haven't pushed B already, that is)
That way, B will include all commits from A, plus its single commit.
If you have shared B (pushed to a common remote repo), the idea is more to add any commit made on A to B (that is, "on top of B).
The simplest way would be to merge A on B, if you don't mind having only one commit on B representing all commits from A.
I would prefer that to any solution involving cherry-picking would mean different SHA1 for each commit recreated on B, which would make any future merge back to A complicated (because Git would go back a long way to find a common ancestor)
the cherry-pick feature is a better way to do this, check answer at
