Try --always, or create some tags. $ git describe --always cfbc47ee2d 83adac3c57:checkout-cache.c That first output confused me for a moment. We can't produce a nice descriptive name for the commit in question, so we punt on the whole thing. Anyway. I have found your diff --find-object to be more useful in practice. I.e.: git log --find-object=cfbc47ee2d because I usually care less about a succinct name, and more about digging into the history (so adding "-p", etc). -Peff
