Git relative revision numbers

Question

Is it possible (somehow) to have in Git (local) relative revision (commit) numbers, like in Mercurial 0, 1, 2, 3, ... instead of short hashes?

Answer 1

You can always refer to a commit by using a prefix of its SHA-1 hash, as long as it is unique. E.g., if you want to checkout 980e3ccdaac54a0d4de358f3fe5d718027d96aae, you can use git checkout 980e as long as no other commits start with 980e.
