How do you find who merged a git commit into a branch?

Question

There is a file in our git repository in work, I want to find out who merged this file into a branch.

I have the commit hash that identifies the commit (lets say 552a976f1a25f9bad57efb9455e951f6b7b3367f) that introduced the file, and I know that the file is on the branch staging.

How can I find the hash of the commit that merged the commit above into the staging branch? I want to find the user who merged, and the date of the merge.

Answer 1

git log -1 --merges <hash>

Will show the most recent merge commit log since the <hash> commit (including itself).
