git - Check if a commit is merged to another branch, and if so, what is the merge commit? -

suppose git repo has 2 branches, master , test. commita made on test branch. want check:

whether commita has been merged master branch? if so, sha of merge commit?

i want check these programmatically (not using gitk).

by example, branch test @ commit commita. can check commita has been merged master command:

git branch --contains test

this should list branches contains commita, check see if master in list.

for getting sha of commita type:

git rev-parse test

the sha of merge commit , commita same.

git merge
