如何打印分支从主分支分支出来的子树？

Question

We have a project in git with lots of branches/tags.

We have a branch master and a branch b1 off master.

How do I get git to show me the commit where branch b1 branched off master. Can I get to print something like:

A
|
B <--E<--F<--b1
|
C
|
D <-- master

or just the tree below B

Answer 1

To get the tree below b1 you could do git log b1 --not master .

Useful when comparing branches is git log --graph b1 master to see your picture as a graph.
