====== 基本的な使い方  ======


ディレクトリ作成
<code>
[root@a3 tmp]# mkdir test.git
[root@a3 tmp]# cd test.git/
</code>
git 初期化
<code>
[root@a3 test.git]# git init
Initialized empty Git repository in /tmp/test.git/.git/
</code>
テストデータ作成
<code>
[root@a3 test.git]# echo "This is test page" > test.html
[root@a3 test.git]# cat test.html 
This is test page
</code>
git 状態確認\\ gitの管理対象外（Untracked files）のファイルとして「test.html」が確認できる
<code>
[root@a3 test.git]# git status
# On branch master
#
# Initial commit
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       test.html
nothing added to commit but untracked files present (use "git add" to track)
</code>
「test.html」をgitの管理下に含める
<code>
[root@a3 test.git]# git add test.html
</code>
git 状態確認\\ gitの管理下・コミット候補（Changes to be committed）のファイルとして「test.html」が確認できる
<code>
[root@a3 test.git]# git status
# On branch master
#
# Initial commit
#
# Changes to be committed:
#   (use "git rm --cached <file>..." to unstage)
#
#       new file:   test.html
#
</code>
git コミットメッセージをつけてコミット\\ ユーザの設定をしていないので、ログインユーザで自動的に設定
<code>
[root@a3 test.git]# git commit -m "first commit"
[master (root-commit) 69c480c] first commit
 Committer: root <root@a3.clown.jp>
Your name and email address were configured automatically based
on your username and hostname. Please check that they are accurate.
You can suppress this message by setting them explicitly:

    git config --global user.name "Your Name"
    git config --global user.email you@example.com

After doing this, you may fix the identity used for this commit with:

    git commit --amend --reset-author

 1 file changed, 1 insertion(+)
 create mode 100644 test.html
</code>
ユーザの設定
<code>
[root@a3 test.git]# git config --global user.name "taro"
[root@a3 test.git]# git config --global user.email taro@mail.com
[root@a3 test.git]# git config --global --list
user.name=taro
user.email=taro@mail.com
</code>
ユーザの設定は実行するたびに上書きされる
<code>
[root@a3 test.git]# git config --global user.name "hanako"
[root@a3 test.git]# git config --global user.email hanako@mail.com
[root@a3 test.git]# git config --global --list
user.name=hanako
user.email=hanako@mail.com
</code>
git コミットログを確認する
<code>
[root@a3 test.git]# git log

例えば、nginxの最新ソースを取得。

<code>
[root@a3 tmp]# mkdir nginx.git
[root@a3 tmp]# cd nginx.git/
[root@a3 nginx.git]# git clone git://github.com/git-mirror/nginx.git
