It's kind of like "git peek-remote", but works only locally (and thus avoids the whole overhead of git_connect()) and has some extra verification features. For example, it allows you to filter the results, and to choose whether you want the tag dereferencing or not. You can also use it to just test whether a particular ref exists. For example: git show-ref master will show all references called "master", whether tags or heads or anything else, and regardless of how deep in the reference naming hierarchy they are (so it would show "refs/heads/master" but also "refs/remote/other-repo/master"). When using the "--verify" flag, the command requires an exact ref path: git show-ref --verify refs/heads/master will only match the exact branch called "master". If nothing matches, show-ref will return an error code of 1, and in the case of verification, it will show an error message. For scripting, you can ask it to be quiet with the "--quiet" flag, which allows you to do things like git-show-ref --quiet --verify -- "refs/heads/$headname" || echo "$headname is not a valid branch" to check whether a particular branch exists or not (notice how we don't actually want to show any results, and we want to use the full refname for it in order to not trigger the problem with ambiguous partial matches). To show only tags, or only proper branch heads, use "--tags" and/or "--heads" respectively (using both means that it shows tags _and_ heads, but not other random references under the refs/ subdirectory). To do automatic tag object dereferencing, use the "-d" or "--dereference" flag, so you can do git show-ref --tags --dereference to get a listing of all tags together with what they dereference.
