How to see which commits in one branch aren't in the other?

Question

I have two branches devel and next. In devel I have a more or less huge amount of commits. Some of the commits are cherry picked in next

Answer 1

The little-used command git cherry shows you the commits which haven't yet been cherry-picked. The documentation for git cherry is here, but, in short, you should just be able to do:

git checkout devel
git cherry next

... and see output a bit like this:

+ 492508acab7b454eee8b805f8ba906056eede0ff
- 5ceb5a9077ddb9e78b1e8f24bfc70e674c627949
+ b4459544c000f4d51d1ec23f279d9cdb19c1d32b
+ b6ce3b78e938644a293b2dd2a15b2fecb1b54cd9

The commits that begin with + will be the ones that you haven't yet cherry-picked into next. In this case, I'd only cherry-picked one commit so far. You might want to add the -v parameter to the git cherry command, so that it also outputs the subject line of each commit.
