## git-tips
> git小贴士：git常用命令集合（git的'奇技淫巧'？😱）

## 所有人看过来
1. Fork于[tips](https://github.com/git-tips/tips)项目

2. **一定要先测试命令的效果后，再用于工作环境中，以防造成不能弥补的后果！**

3. 所有的命令都在`git version 2.7.4 (Apple Git-66)`下测试通过（安全可食用😊）

## 统一概念
1. 工作区：改动（增删文件和文本）
2. 暂存区：输入命令：`git add 改动的文件名`，此次改动就放到了‘暂存区’
3. 本地仓库：输入命令：`git commit 此次修改的描述`，此次改动就放到了’本地仓库’，每个commit，我叫它为一个‘版本’
4. 远程仓库：输入命令：`git push 远程仓库`，此次改动就放到了‘远程仓库’（github等)

## Everyday Git in twenty commands or so
```sh
git help everyday
```

## Show helpful guides that come with Git
```sh
git help -g
```

## 回到远程仓库的状态
抛弃本地仓库的所有版本(commit)，回到远程仓库的状态。  
```sh
git fetch --all && git reset --hard origin/master
```

## 重设第一个commit
也就是把所有的改动都重新放回工作区，并**清空所有的commit**，这样就可以重新提交第一个commit了
```sh
git update-ref -d HEAD
```

## 展示工作区和最近版本的不同
输出**工作区**和本地中最近的版本(commit)的different(不同)。
```sh
git diff
```

## 展示暂存区和最近版本的不同
输出**暂存区**和本地最近的版本(commit)的different(不同)。
```sh
git diff --cached
```

## 展示暂存区、工作区和最近版本的不同
输出**工作区**、**暂存区** 和本地最近的版本(commit)的different(不同)。
```sh
git diff HEAD
```

```

## 展示所有的分支关联的远程仓库
```sh
git branch -vv
```

## 关联远程分支
关联之后，`git branch -vv`就可以展示关联的远程分支名了，同时推送到远程仓库直接：`git push`，不需要指定远程仓库了。
```sh
git branch -u origin/mybranch
```

## 删除本地分支
```sh
git branch -d <local_branchname>
```

## 删除远程分支
```sh
git push origin --delete <remote_branchname>
```

git checkout -- <file_name>
```

git remote set-url origin <URL>
```

```sh
git remote
```

## 列出本地和远程分支
-a参数相当于：all
```sh

git branch -r
```

```sh
git add -p
```

curl http://git.io/vfhol > ~/.git-completion.bash && echo '[ -f ~/.git-completion.bash ] && . ~/.git-completion.bash' >> ~/.bashrc
