git log

1.git init //初始化本地库
.git目录的简要说明:
===========================================================
表 1 .git 目录简要说明

子目录名 简要描述
branches Git 项目分支信息，新版 Git 已经不再使用该目录。
config Git 项目配置信息
description Git 项目描述信息
HEAD 指向 Git 项目当前分支的头指针
hooks 默认的"hooks"脚本，被特定事件发生前后触发。
info 里面含一个 exclude 文件，指 Git 项目要忽略的文件。
objects Git 的数据对象，包括：commits, trees, blobs, tags。
refs 指向所有 Git 项目分支的指针
====================================================================
2.git clone 版本库名称 //检出库内容
[针对第二类 Git 仓库，我们不需要 git init 初始化仓库，取而代之的是，使用 git clone 直接将远程镜像克隆到本地仓库。

3.//创建用户&mail
[如果是第一次使用 Git，均需要配置用户信息，包括用户名与 Email（如下所示），以便以后每次 Git 提交时都可以自动引用这两条信息，说明是谁更新与提交了代码。http://www.ibm.com/developerworks/cn/opensource/os-cn-tourofgit/ ]
git config --global user.email "usermail@xxx"
git config --global user.name "username"
4.//增加修改到本地缓存
git add filename //add file ,* is ok
git commit -m "xxxx" //提交修改到本地缓存
5.//推送修改到远端库
git push orign master //master为本地要推送的分支名称
add test

[popexizhi:ok,pope常犯的错误命令应该是
git push origin master
自己写成了:git push origin master
]
[参考:http://www.ibm.com/developerworks/cn/opensource/os-cn-tourofgit/]
6.//拉取修改版本
[popexizhi:git 这个很帅,pope执行时提示如下
E:\pc\other\thinking\learning\testgit\xizhi>git push origin master

hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
之后直接尝试]
git pull 再次尝试git push origin master 就ok 了。
----------------------------
而要将远程仓库抓取数据到本地，可以使用 git fetch 命令，从而获取所有本地仓库中还没有的数据。
$ git fetch [remote-name]
如果设置了某个分支用于跟踪某个远端仓库的分支，可以使用 git pull 命令自动抓取数据下来，然后将远端分支自动合并到本地仓库中当前分支。从这个角度，git pull 等价于 git fetch + git merge 的功能。
$ git pull [remote-name]

[popexizhi:
1.log写的好乱，应该找个好方法更新记录结构了:)
2.http://www.ibm.com/developerworks/cn/opensource/os-cn-tourofgit/
IBM的这个内容写的很不错哟，好好阅读一下写写笔记吧
3.popexizhi计划的git使用方案，和其他代码的迁移是否要做thinking
