+# 常用 Screen 命令大全
+
+## 创建会话（最常用）
+
+- `screen -U -S vllm_server` → 新建并命名
+- `screen -U -dmS vllm_server` → **新建后立即分离**（最推荐！直接后台启动）
+- `screen -U -dmS vllm_server "python -m vllm serve …"` → 新建 + 直接执行命令（一键启动服务）
+
+## 管理会话
+
+- `screen -U -ls` 或 `screen -U -list` → 列出所有会话（你现在用的）
+- `screen -U -r` → 进入最后一个会话
+- `screen -U -r vllm_server` → 按名字进入（推荐，比数字更稳）
+- `screen -U -r 89505` → 只输入数字也可以（简写）
+- `screen -U -S vllm_server -X quit` → 杀死指定会话（你现在用的）
+- `screen -wipe` → 清理已死亡的会话记录（偶尔用）
+
+# 在 screen 里面的快捷键（记住这几个就够用 90%）
+
+| 快捷键 | 功能 |
+|--------|------|
+| `Ctrl-a ?` | 显示帮助（所有快捷键列表） |
+| `Ctrl-a c` | 新建一个窗口（像 tab） |
+| `Ctrl-a n` / `Ctrl-a p` | 切换到下一个/上一个窗口 |
+| `Ctrl-a 0~9` | 直接跳到第几个窗口 |
+| `Ctrl-a d` | 分离（退出） |
+| `Ctrl-a k` | 杀死当前窗口（确认 y） |
+| `Ctrl-a A` | 重命名当前窗口（好认） |
+| `Ctrl-a "` | 显示窗口列表，选择切换 |
+
+# 高级实用技巧
+
+- 滚动屏幕：`Ctrl-a [` → 进入复制模式，用上下键翻历史，按 `Esc` 退出
+- 发送命令给后台会话：`screen -S vllm_server -X stuff "echo hello\n"`
+- 自动启动 vLLM（推荐写进脚本）：
+
+  ```bash
+  screen -U -dmS vllm_server
+  screen -S vllm_server -X stuff "python -m vllm serve --model /root/autodl-tmp/DeepSeek-R1-1.5B --port 8000\n"
+  ```
