References of Git
Getting Started - With a References of Git
Every object in the Git database that is not referred to may be cleaned up by using a garbage collection command or automatically. An object may be referenced by another object or an explicit reference. Git knows different types of references. The commands to create, move, and delete references vary. "git show-ref" lists all references. Some types are:
heads: refers to an object locally,
Remotes: refers to an object which exists in a remote repository,
Stash: refers to an object not yet committed,
e.g. a configuration in a bare repository, user rights; the refs/meta/config namespace was introduced retrospectively, gets used by Gerrit
tags: see above.
