-v0.99.4, Aug 2005
NAME
----
SYNOPSIS
--------
-'git-<command>' <args>
+'git' [--version] [--exec-path[=GIT_EXEC_PATH]] [--help] COMMAND [ARGS]
DESCRIPTION
-----------
+Git is a fast, scalable, distributed revision control system with an
+unusually rich command set that provides both high-level operations
+and full access to internals.
+
+See this link:tutorial.html[tutorial] to get started, then see
+link:everyday.html[Everyday Git] for a useful minimum set of commands, and
+"man git-commandname" for documentation of each command. CVS users may
+also want to read link:cvs-migration.html[CVS migration].
+
+OPTIONS
+-------
+--version::
+ Prints the git suite version that the 'git' program came from.
+
+--help::
+ Prints the synopsis and a list of the most commonly used
+ commands. If a git command is named this option will bring up
+ the man-page for that command. If the option '--all' or '-a' is
+ given then all available commands are printed.
+
+--exec-path::
+ Path to wherever your core git programs are installed.
+ This can also be controlled by setting the GIT_EXEC_PATH
+ environment variable. If no path is given 'git' will print
+ the current setting and then exit.
+
+
+FURTHER DOCUMENTATION
+---------------------
-This is reference information for the core git commands.
-
-Before reading this cover to cover, you may want to take a look
-at the link:tutorial.html[tutorial] document.
-
-The Discussion section below contains much useful definition and
-clarification info - read that first. And of the commands, I suggest
-reading link:git-update-cache.html[git-update-cache] and
-link:git-read-tree.html[git-read-tree] first - I wish I had!
+See the references above to get started using git. The following is
+probably more detail than necessary for a first-time user.
-After you get the general feel from the tutorial and this
-overview page, you may want to take a look at the
-link:howto-index.html[howto] documents.
+The <<Discussion,Discussion>> section below and the
+link:core-tutorial.html[Core tutorial] both provide introductions to the
+underlying git architecture.
+See also the link:howto-index.html[howto] documents for some useful
+examples.

+GIT COMMANDS
+------------
-Updated by Junio C Hamano <junkio@cox.net> on 2005-05-05 to
-reflect recent changes.
+We divide git into high level ("porcelain") commands and low level
+("plumbing") commands.
-Commands Overview
------------------
-The git commands can helpfully be split into those that manipulate
-the repository, the cache and the working fileset, those that
-interrogate and compare them, and those that moves objects and
-references between repositories.
+Low-level commands (plumbing)
+-----------------------------
-In addition, git itself comes with a spartan set of porcelain
-commands. They are usable but are not meant to compete with real
-Porcelains.
+Although git includes its
+own porcelain layer, its low-level commands are sufficient to support
+development of alternative porcelains. Developers of such porcelains
+might start by reading about gitlink:git-update-index[1] and
+gitlink:git-read-tree[1].
-There are also some ancillary programs that can be viewed as useful
-aids for using the core commands but which are unlikely to be used by
-SCMs layered over git.
+We divide the low-level commands into commands that manipulate objects (in
+the repository, index, and working tree), commands that interrogate and
+compare objects, and commands that move objects and references between
+repositories.

+Configuration Mechanism
+-----------------------
+
+Starting from 0.99.9 (actually mid 0.99.8.GIT), `.git/config` file
+is used to hold per-repository configuration options. It is a
+simple text file modelled after `.ini` format familiar to some
+people. Here is an example:
+
+------------
+#
+# A '#' or ';' character indicates a comment.
+#
+
+; core variables
+[core]
+ ; Don't trust file modes
+ filemode = false
+
+; user identity
+[user]
+ name = "Junio C Hamano"
+ email = "junkio@twinsun.com"
+
+------------
+
+Various commands read from the configuration file and adjust
+their operation accordingly.
Identifier Terminology
----------------------
<object>::
- Indicates the sha1 identifier for any type of object
+ Indicates the object name for any type of object.
<blob>::
- Indicates a blob object sha1 identifier
+ Indicates a blob object name.
<tree>::
- Indicates a tree object sha1 identifier
+ Indicates a tree object name.
<commit>::
- Indicates a commit object sha1 identifier
+ Indicates a commit object name.
<tree-ish>::
- Indicates a tree, commit or tag object sha1 identifier. A
+ Indicates a tree, commit or tag object name. A
command that takes a <tree-ish> argument ultimately wants to
operate on a <tree> object but automatically dereferences
<commit> and <tag> objects that point at a <tree>.
<type>::
Indicates that an object type is required.
- Currently one of: blob/tree/commit/tag
+ Currently one of: `blob`, `tree`, `commit`, or `tag`.
<file>::
- Indicates a filename - always relative to the root of
- the tree structure GIT_INDEX_FILE describes.
+ Indicates a filename - almost always relative to the
+ root of the tree structure `GIT_INDEX_FILE` describes.
Symbolic Identifiers
--------------------
symbolic notation:
HEAD::
- indicates the head of the repository (ie the contents of
- `$GIT_DIR/HEAD`)
+ indicates the head of the current branch (i.e. the
+ contents of `$GIT_DIR/HEAD`).
+
<tag>::
- a valid tag 'name'+
- (ie the contents of `$GIT_DIR/refs/tags/<tag>`)
+ a valid tag 'name'
+ (i.e. the contents of `$GIT_DIR/refs/tags/<tag>`).
+
<head>::
- a valid head 'name'+
- (ie the contents of `$GIT_DIR/refs/heads/<head>`)
-<snap>::
- a valid snapshot 'name'+
- (ie the contents of `$GIT_DIR/refs/snap/<snap>`)
+ a valid head 'name'
+ (i.e. the contents of `$GIT_DIR/refs/heads/<head>`).
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)
