The command git-name-rev satisfies this need partially by listing symbolic names for given commits. Is there a command that can do this more generally? In particular, I am looking for a command that will return a list of commits that point to a particular tree. Right now I plan to brute force it. Basically, I will call git-rev-list to list the commits and, for each commit, map it to a tree. Then, I will reverse the map in order to be able to look up a commit based on the tree. I was thinking, though, that it might be somewhat useful in general to, at least, provide a command for the following: - Given a blob, list the tree and/or tag objects that reference that blob. - Given a tree, list the tree, commit and/or tag objects that reference it. - Given a commit, list the commit and/or tag objects that reference it.

You might want to explain what problem you are trying to solve, by knowing which commit contains a particular tree object. There might be a solution to that unstated problem which does not require the reverse lookup. ```
