Identifier Terminology
File/Directory Structure
------------------------
-The git-core manipulates the following areas in the directory:
-
- .git/ The base (overridden with $GIT_DIR)
- objects/ The object base (overridden with $GIT_OBJECT_DIRECTORY)
- ??/ 'First 2 chars of object' directories.
- pack/ Packed archives.
- refs/ Directories containing symbolic names for objects
- (each file contains the hex SHA1 + newline)
- heads/ Commits which are heads of various sorts
- tags/ Tags, by the tag name (or some local renaming of it)
- */ Any other subdirectory of refs/ can be used to store
- files similar to what are under refs/heads/.
- HEAD Symlink to refs/heads/<current-branch-name>
+Please see link:repository-layout.html[repository layout] document.
Higher level SCMs may provide and manage additional information in the
GIT_DIR.
