You can use `git rev-parse --verify HEAD`, for example.  Generally
scripted commands (including those in contrib/examples/) are good
sources of inspiration.  Or if you want symbolic name, you can use
`git symbolic-ref HEAD` or `git rev-parse --symbolic-full-name HEAD`.

As for `git show-ref HEAD` - git-show-ref uses its own way of pattern
matching; in new enough version of git-show-ref manpage you can read
that:

  <pattern>...::

        Show references matching one or more patterns. Patterns are matched from
        the end of the full name, and only complete parts are matched, e.g.
        'master' matches 'refs/heads/master', 'refs/remotes/origin/master',
        'refs/tags/jedi/master' but not 'refs/heads/mymaster' nor
        'refs/remotes/master/jedi'.

So `git show-ref HEAD` would match 'refs/.../HEAD`, e.g. `refs/remotes/origin/HEAD`,
but not `HEAD` which is outside `refs/`.

I tripped over strange git-show-ref <pattern> semantic too.

P.S. there is also git-for-each-ref.
