git备忘（长久更新）
一直想了解一下git，正好最近的有一个问题就是，实验室写的代码，怎么同步到自己宿舍的笔记本上面来。最开始想用dropbox，但是用VS的人都知道，工程文件里面会给你生成乱七八糟的很多东西，很占空间，dropbox好像没有选择同步某个文件的功能，只能同步某个文件夹。以前看过git，但是好久没用，隔了一俩个月就忘了。这里把常用的概念、命令做个笔记。
资料大部分来源于这里
1.文件的三种状态：已提交（committed），已修改（modified）和已暂存（staged）。已提交表示该文件已经被安全地保存在本地数据库中了；已修改表示修改了某个文件，但还没有提交保存；已暂存表示把已修改的文件放在下次提交时要保存的清单中。
2. git config --global user.name
git config --global user.email --//设置账号
git config --list --//查看配置列表
git clone [url] --//获取仓库
git status --//检查当前文件文件状态
git add --//1)添加某个文件 2）将文件从已修改的状态变到已暂存的状态
--//在整个工程文件夹下，git init 了之后，设置好.gitignore规则之后输入命令 git add . 就可以添加所有的工程文件。
git commit -m "init first project" --//这个是提交，从已暂存的状态转变到已提交的状态 -m 参数 后面跟此次提交的说明
git commit -a --//此命令跳过git add过程，即跳过已暂存的状态 直接从已修改--》已提交
git remote -v --//显示远程仓库的名字和位置
git remote add [shortname] [url] --//添加远程仓库
git remote rename a b --//将仓库名字a改为b
git push -u origin master --//将本地的分支push到远程仓库里面
git rm [filename] --//删除文件
3. .gitignore 在这个文件里面，git会根据文件里面的规则忽略指定文件。下面是一个从网上淘来的VS工程的模版
