git - find files changed in branch, since created

Question

I would like to get a list of files which were changed in branch, since branch was created.

Example:

• create branch B1

• commit change in file_1

• commit change in file_2

Result should be: file_1 file_2

How to do that?

I'm NOT interested in difference between Master and B1.

I'm interested in difference between current state of B1 and primary state of B1.

Thanks for responses

Answer 1

First, find the diverge point using

git merge-base master b1

Then use

git diff --stat <commit-id>..b1
