Which commit has this blob?

Question

Given the hash of a blob, is there a way to get a list of commits that have this blob in their tree?

Answer 1

Unfortunately scripts were a bit slow for me, so I had to optimize a bit. Luckily I had not only the hash but also the path of a file.

git log --all --pretty=format:%H --  | xargs -n1 -I% sh -c "git ls-tree % --  | grep -q  && echo %"
