+# Crontab UI (macOS)
+
+網頁版的排程與程序管理面板，直接操作 macOS 的系統 `crontab`，並整合 PM2、Node.js 程序、Docker 與 log 檢視。
+
+單一 Node.js 伺服器（Express）+ 單一 HTML 前端，無框架、無建置步驟。
+
+> Windows 移植版請見 `master` 分支。
+
+## 功能
+
+| 頁籤 | 說明 |
+|---|---|
+| ⏰ Crontab | 讀寫**系統 crontab**（`crontab -l` / `crontab <file>`），支援新增、編輯、啟用／停用、刪除、任務備註（label） |
+| 🟢 PM2 | 列出 PM2 程序（狀態、PID、CPU、記憶體、重啟次數、監聽 port），可啟動／停止／重啟／刪除 |
+| 🟡 Node.js | 列出系統上所有 node / bun 程序（`ps aux`），可結束程序（`kill -15` / `kill -9`） |
+| 🐳 Docker | 列出容器並可啟動／停止／重啟（需安裝 Docker） |
+| 📋 Log | 瀏覽 log 目錄下的 `.log` 檔案，支援 tail 與自動刷新 |
+
+## 安裝與執行
+
+需求：Node.js 18+、macOS（或其他有 crontab 的 Unix 系統）
+
+```bash
+npm install
+node server.js
+```
+
+開啟 <http://localhost:3789>
+
+### 用 PM2 背景常駐（建議）
+
+```bash
+npm install -g pm2
+pm2 start server.js --name crontab-ui
+pm2 save
+pm2 startup   # 依照輸出的指令設定開機自動啟動（launchd）
+```
+
+## 環境變數
+
+| 變數 | 預設值 | 說明 |
+|---|---|---|
+| `PORT` | `3789` | 網頁伺服器 port |
+| `LOG_DIR` | `/Volumes/HDD/Claude/logs` | Log 頁籤讀取的目錄 |
+
+## 運作方式
+
+- 排程任務由**系統 cron** 執行，本工具只負責讀寫 crontab 內容；伺服器停止不影響排程執行
+- 任務上方緊鄰的 `#` 註解行會被視為該任務的備註（label），在 UI 中一併顯示與編輯
+- 停用任務 = 在該行前面加 `#`，啟用 = 移除
+- 監聽 port 以 `lsof -iTCP -sTCP:LISTEN` 偵測後對應到 PM2 程序
