Git: show branches that have different commits compared to master?

Question

I have a repo that got quite large with several branches. I rebased some important stuff and merged branches that I might need in future - so far, so good. However, I have the feeling that I am missing some old branch that never got merged into master . Due to the size of the repo and amount of commits it is hard to scroll through and identify the problem with gitg or git log --online --decorate --graph --all .

Is it possible to somehow reduce the graph to just the most recent commit for every branch and preferably only stuff that is different to master ?

Answer 1

You specify the refspec ^master (not reachable from master). That should get you going

git log --all ^master
