That doesn't work for me (git 1.7.10.4 as per Fedora 18 rpms) in git.git. But the idea is sound -- git can give you the sha1 trivially. You don't need additional glue.

But any ref definition can be turned into a sha1 with this snippet:

    git show --pretty=format:%H HEAD

If you want to get the last 10 sha1s, use the same "pretty" with git log

   git log --pretty=format:%H HEAD | head

This is all predicated on passing the info to something else. For git commands, you can always use the rich ref notation git supports.

cheers,
