$ git config --list
初次使用推荐配置
$ git config --global user.name "xxx"
$ git config --global user.email xxx@xxx.com
配置默认文本编辑器
$ git config --global core.editor emacs [可选vim, vi等]
配置默认差异比较工具
$ git config --global merge.tool vimdiff [可选kdiff3，tkdiff，meld，xxdiff，emerge，vimdiff，gvimdiff，ecmerge，和 opendiff 等]

$ git help config

初始化，将当前项目纳入版本控制
$ git init
添加文件到版本控制
$ git add *.js
$ git add README
$ git add --all
查看当前版本状态
$ git status
提交变更
$ git commit -m "comment"

克隆仓库项目至本地,默认新建repo目录
$ git clone git://git.repo.com/repo.git
克隆仓库至本地指定目录
$ git clone https://github.com/dyfeelme/dyfeelme.github.io blog

用户级别的gitignore,一般存放在用户目录下，当然也可以在.gitconfig中指定其他位置。项目自定义的则存放于项目根目录（与.git目录同级），如下：
$ cat ~/.gitignore
*.swp
build
.DS_store
如上为用户级别的gitignore,指定了所有以.swp为后缀的文件，build目录和.DS_store目录。
$ cat project/.gitignore
.settings
build
*.iso
如上为项目级别的gitignore,其中指定了.settings目录,build目录和所有以.iso为后缀的镜像文件。

$ git diff 比较当前文件和暂存区域快照的差异
$ git diff --cache 或 --staged 比较暂存区域和上次提交版本快照的差异

移除
$ git rm file 将文件从已跟踪文件清单中移除，区别于直接rm命令删除
重命名
$ git mv file newfile 重名名文件，虽然git不像svn等会记录文件改名操作，但git通过以下命令组合完成了改名操作
$ mv file newfile && git rm file && git add newfile

$ git log 查看提交日志
可选参数
-p 按补丁格式显示每个更新之间的差异。
--stat 显示每次更新的文件修改统计信息。
--shortstat 只显示 --stat 中最后的行数修改添加移除统计。
--name-only 仅在提交信息后显示已修改的文件清单。
--name-status 显示新增、修改、删除的文件清单。
--abbrev-commit 仅显示 SHA-1 的前几个字符，而非所有的 40 个字符。
--relative-date 使用较短的相对时间显示（比如，“2 weeks ago”）。
--graph 显示 ASCII 图形表示的分支合并历史。
--pretty 使用其他格式显示历史提交信息。可用的选项包括 oneline，short，full，fuller 和 format（后跟指定格式）。
