# Git操作记录

本文档记录了在仓库中执行的主要Git操作步骤和结果。

## 1. 初始化本地Git仓库

**操作命令：**
```bash
git init
```

**执行结果：**
```
Initialized empty Git repository in D:/工作/笔记/.git/
```

## 2. 设置远程仓库链接

**操作命令：**
```bash
git remote add origin https://git.tsama.cn/bb/BiJi.git
```

**执行结果：** 成功添加远程仓库引用

## 3. 添加并提交文件

**操作命令：**
```bash
git add .
```

**执行结果：**
```

```

**提交命令：**
```bash
git commit -m "初始化提交"
```

**执行结果：**
```
[master (root-commit) 5b02c1a] 初始化提交

```

## 4. 推送到远程仓库

**操作命令：**
```bash
git push -u origin master
```

**执行结果：**
```

remote:
remote: . Processing 1 references
remote: Processed 1 references in total
To https://git.tsama.cn/bb/BiJi.git
 * [new branch]      master -> master
branch 'master' set up to track 'origin/master'.
```

## 5. 分支管理操作

### 查看分支状态

**操作命令：**
```bash
git branch -a
```

**初始状态：**
```
* master
  remotes/origin/HEAD -> origin/main
  remotes/origin/main
  remotes/origin/master
```

### 尝试删除默认分支（失败）

**操作命令：**
```bash
git push origin --delete main
```

**失败结果：**
```
remote:
remote: error:
remote: error: branch main is the default branch and cannot be deleted
remote: error:
To https://git.tsama.cn/bb/BiJi.git
 ! [remote rejected] main (pre-receive hook declined)
error: failed to push some refs to 'https://git.tsama.cn/bb/BiJi.git'
```

### 更改本地远程HEAD引用

**操作命令：**
```bash
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master
```

### 通过Web界面更改默认分支

在Git服务器Web界面执行以下操作：
1. 登录到Git服务器（https://git.tsama.cn）
2. 进入BiJi仓库设置
3. 将默认分支从main更改为master

### 成功删除远程main分支

**操作命令：**
```bash
git push origin --delete main
```

**执行结果：**
```
remote: . Processing 1 references
remote: Processed 1 references in total
To https://git.tsama.cn/bb/BiJi.git
 - [deleted]         main
```

## 6. 最终分支状态确认

**操作命令：**
```bash
git branch -a
```

**最终状态：**
```
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
```

## 总结

通过以上操作，我们成功地：
1. 初始化了本地Git仓库并与远程仓库关联
2. 提交并推送了初始代码
3. 成功将远程仓库结构简化为仅保留master分支

现在仓库结构更加清晰，所有开发工作都将在master分支上进行。
