Question

Is there a way to retrieve all the SHA1’s for all objects (blobs and trees) inside of a particular commit in git?

Answer 1

I’m pretty sure that git rev-list will do what you want:

git rev-list --no-walk <commit> --objects

See the documentation on git rev-list for more information at http://www.kernel.org/pub/software/scm/git/docs/git-rev-list.html.

Edit: Added --no-walk as per Paŭlo Ebermann’s suggestion; this will only show the objects for the given ref, without the ancestor commits.
