git(1)
======
v0.1, May 2005
NAME
----
git - the stupid content tracker
SYNOPSIS
--------
'git-<command>' <args>
DESCRIPTION
-----------
This is reference information for the core git commands.
The link:README[] contains much useful definition and clarification
info - read that first. And of the commands, I suggest reading
'git-update-cache' and 'git-read-tree' first - I wish I had!

Updated by Junio C Hamano <junkio@cox.net> on 2005-05-05 to
reflect recent changes.
Commands Overview

the repository, the cache and the working fileset and those that
interrogate and compare them.

Terminology
-----------
see README for description
Identifier terminology
----------------------
<object>::
Indicates any object sha1 identifier
<blob>::
Indicates a blob object sha1 identifier
<tree>::
Indicates a tree object sha1 identifier
<commit>::
Indicates a commit object sha1 identifier
<tree-ish>::
Indicates a tree, commit or tag object sha1 identifier.
A command that takes a <tree-ish> argument ultimately
wants to operate on a <tree> object but automatically
dereferences <commit> and <tag> that points at a
<tree>.
<type>::
Indicates that an object type is required.
Currently one of: blob/tree/commit/tag
<file>::
Indicates a filename - always relative to the root of
the tree structure GIT_INDEX_FILE describes.
Terminology
-----------
Each line contains terms used interchangeably
object database, .git directory
directory cache, index
id, sha1, sha1-id, sha1 hash
type, tag
blob, blob object
tree, tree object
commit, commit object
parent
root object
changeset
Environment Variables
---------------------
Various git commands use the following environment variables:
- 'GIT_AUTHOR_NAME'
- 'GIT_AUTHOR_EMAIL'
- 'GIT_AUTHOR_DATE'
- 'GIT_COMMITTER_NAME'
- 'GIT_COMMITTER_EMAIL'
- 'GIT_DIFF_OPTS'
