 ### Scheduled Tasks
 
 <details>
-<summary markdown="span">Set up scheduled tasks to run automatically</summary>
+<summary markdown="span">Use built-in task command to set up scheduled tasks (checks IP every 5 minutes by default for automatic updates)</summary>
 
-This tool itself does not include loop and scheduled execution functions (to reduce code complexity). You can use system scheduled tasks to run regularly.
+DDNS provides a built-in `task` subcommand for managing scheduled tasks with cross-platform automated deployment:
 
-#### Windows
+#### Basic Usage
 
-- [Recommended] Run as system identity, right-click "Run as administrator" on `task.bat` (or run in administrator command line)
-- Run scheduled task as current user, double-click or run `task.bat` (a black window will flash during execution)
+```bash
+# Install scheduled task (default 5-minute interval)
+ddns task --install --dns dnspod --id your_id --token your_token --ipv4 your.domain.com
+
+# Check task status
+ddns task --status
+
+# Uninstall scheduled task
+ddns task --uninstall
+```
 
-#### Linux
+#### Supported Systems
 
-- Using init.d and crontab:
+- **Windows**: Uses Task Scheduler
+- **Linux**: Automatically selects systemd or crontab
+- **macOS**: Uses launchd
 
-  ```bash
-  sudo ./task.sh
-  ```
+#### Advanced Management
 
-- Using systemd:
+```bash
+# Install with custom interval (minutes)
+ddns task --install 10 -c /etc/ddns/config.json
+
+# Enable/disable tasks
+ddns task --enable
+ddns task --disable
+```
 
-  ```bash
-  Install:
-  sudo ./systemd.sh install
-  Uninstall:
-  sudo ./systemd.sh uninstall
-  ```
+> **New Feature Advantages**:
+>
+> - ✅ Cross-platform automatic system detection
+> - ✅ Automatically overwrites existing tasks without manual uninstallation
+> - ✅ Supports all DDNS configuration parameters
+> - ✅ Unified command-line interface
 
-  Files installed by this script comply with [Filesystem Hierarchy Standard (FHS)](https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard):
-  Executable files are located in `/usr/share/DDNS`
-  Configuration files are located in `/etc/DDNS`

 5. **Regular Expressions**: When using regular expressions, special characters need to be properly escaped. It's recommended to use quotes, for example: `--index4 "regex:192\\.168\\..*"`.
 
+## Task Management
+
+DDNS supports managing scheduled tasks through the `task` subcommand, which automatically detects the system and selects the appropriate scheduler to install scheduled update tasks.
+
+### Key Features
+
+- **Smart Installation**: The `--install` command automatically overwrites existing tasks, simplifying the installation process
+- **Cross-Platform Support**: Automatically detects system and selects the best scheduler
+- **Complete Configuration**: Supports all DDNS configuration parameters
+
+### Task Subcommand Usage
+
+```bash
+# View help
+ddns task --help
+
+# Check task status
+ddns task --status
+
+# Install scheduled task (default 5-minute interval)
+ddns task --install
+
+# Install scheduled task with custom interval (minutes)
+ddns task --install 10
+ddns task -i 15
+
+# Specify scheduler type for installation
+ddns task --install 5 --scheduler systemd
+ddns task --install 10 --scheduler cron
+ddns task --install 15 --scheduler auto
+
+# Enable installed scheduled task
+ddns task --enable
+
+# Disable installed scheduled task
+ddns task --disable
+
+# Uninstall installed scheduled task
+ddns task --uninstall
+```
+
+### Supported Schedulers
+
+DDNS automatically detects the system and chooses the most appropriate scheduler:
+
+- **Linux**: systemd (preferred) or cron
+- **macOS**: launchd (preferred) or cron  
+- **Windows**: schtasks
+
+### Scheduler Selection Guide
+
+| Scheduler | Supported Systems | Description | Recommendation |
+|-----------|-------------------|-------------|----------------|
+| `auto` | All systems | Automatically detects system and selects the best scheduler | ⭐⭐⭐⭐⭐ |
+| `systemd` | Linux | Modern Linux standard timer with complete functionality | ⭐⭐⭐⭐⭐ |
+| `cron` | Unix-like | Traditional Unix scheduled tasks with good compatibility | ⭐⭐⭐⭐ |
+| `launchd` | macOS | macOS native task scheduler | ⭐⭐⭐⭐⭐ |
+| `schtasks` | Windows | Windows Task Scheduler | ⭐⭐⭐⭐⭐ |
+
+### Parameter Description
+
+| Parameter | Description |
+|-----------|-------------|
+| `--status` | Show scheduled task installation status and running information |
+| `--install [minutes]`, `-i [minutes]` | Install scheduled task with update interval (default: 5 minutes). **Automatically overwrites existing tasks** |
+| `--uninstall` | Uninstall installed scheduled task |
+| `--enable` | Enable installed scheduled task |
+| `--disable` | Disable installed scheduled task |
+| `--scheduler` | Specify scheduler type. Supports: auto, systemd, cron, launchd, schtasks |
+
+> **Installation Behavior**:
+>
+> - The `--install` command always executes installation directly, without prior checking or uninstalling.
+> - Any existing DDNS scheduled task in the system will be automatically replaced with the new configuration.
+> - This design simplifies task management and avoids the hassle of manual uninstallation, enabling one-click task updates.
+>
+> **Configuration Parameter Support**: The `task` subcommand supports all DDNS configuration parameters, which will be passed to the scheduled task for execution.
+
+### Permission Requirements
+
+Different schedulers require different permissions:
+
+- **systemd**: Requires root privileges (`sudo`)
+- **cron**: Regular user privileges
+- **launchd**: Regular user privileges
+- **schtasks**: Administrator privileges required
+
+### Task Management Examples
+
+```bash
+# Check current status
+ddns task --status
+
+# Quick install (automatically overwrites existing tasks)
+ddns task --install
+
+# Install 10-minute interval scheduled task with specified config file
+ddns task --install 10 -c /etc/ddns/config.json
+
+# Install scheduled task with direct DDNS parameters (no config file needed)
+ddns task --install 5 --dns cloudflare --id [email protected] --token API_TOKEN --ipv4 example.com
+
+# Install scheduled task with advanced configuration parameters
+ddns task --install 10 --dns dnspod --id 12345 --token secret \
+          --ipv4 example.com --ttl 600 --proxy http://proxy:8080 \
+          --log_file /var/log/ddns.log --log_level INFO
+
+# Specify scheduler type for installation
+ddns task --install 5 --scheduler systemd --dns cloudflare --id [email protected] --token API_TOKEN --ipv4 example.com
+
+# Force use cron scheduler (for Linux systems without systemd)
+ddns task --install 10 --scheduler cron -c config.json
+
+# Force use launchd on macOS
+ddns task --install 15 --scheduler launchd --dns dnspod --id 12345 --token secret --ipv4 example.com
+
+# Use schtasks on Windows
+ddns task --install 5 --scheduler schtasks --dns cloudflare --id [email protected] --token API_TOKEN --ipv4 example.com
+
+# Install systemd timer on Linux with sudo
+sudo ddns task --install 5 -c /etc/ddns/config.json
+
+# Update task configuration (automatic overwrite)
+ddns task --install 15 --dns cloudflare --id [email protected] --token NEW_TOKEN --ipv4 example.com
+
+# Enable installed task
+ddns task --enable
+
+# Disable task (doesn't delete, just stops execution)
+ddns task --disable
+
+# Completely uninstall scheduled task
+ddns task --uninstall
+```
+
+### Using with Configuration Files
+
+The `task` subcommand works perfectly with configuration files, supporting multiple configuration methods:
+
+```bash
+# Use local configuration file
+ddns task --install 10 -c config.json
+
+# Use multiple configuration files
+ddns task --install 5 -c cloudflare.json -c dnspod.json
+
+# Use remote configuration file
+ddns task --install 15 -c https://config.example.com/ddns.json
+
+# Configuration file + command line parameter override
+ddns task --install 10 -c config.json --debug --ttl 300
+
+# Specify scheduler type + configuration file
+ddns task --install 5 --scheduler cron -c config.json
+
+# Use remote configuration file + specify scheduler
+ddns task --install 10 --scheduler systemd -c https://config.example.com/ddns.json
+```
+
+### Scheduler Usage Examples
+
+Choose the appropriate scheduler based on different systems and requirements:
+
+```bash
+# Automatic selection (recommended, let system choose the best scheduler)
+ddns task --install 5 --scheduler auto
+
+# Linux system choices
+ddns task --install 5 --scheduler systemd  # Preferred choice, full functionality
+ddns task --install 5 --scheduler cron     # Backup choice, good compatibility
+
+# macOS system choices
+ddns task --install 5 --scheduler launchd  # Preferred choice, system native
+ddns task --install 5 --scheduler cron     # Backup choice, good compatibility
+
+# Windows system choices
+ddns task --install 5 --scheduler schtasks # Only choice, Windows Task Scheduler
+```
+
+### Debugging Installation Issues
+
+```bash
+# Enable debug mode to view detailed installation process
+ddns task --install 5 --debug
+
+# View task status and configuration
+ddns task --status --debug
+
+# View status of specified scheduler
+ddns task --status --scheduler systemd --debug
+```
+
+# Configuration file + command line parameter override
+
+ddns task --install 10 -c config.json --debug --ttl 300
+
+```
+
+### Debugging Installation Issues
+
+```bash
+# Enable debug mode to see detailed installation process
+ddns task --install 5 --debug
+
+# View task status and configuration
+ddns task --status --debug
+```

+## Task Management (定时任务管理)
+
+DDNS 支持通过 `task` 子命令管理定时任务，可自动根据系统选择合适的调度器安装定时更新任务。
+
+### 重要特性
+
+- **智能安装**: `--install` 命令自动覆盖已有任务，简化安装流程
+- **跨平台支持**: 自动检测系统并选择最佳调度器
+- **完整配置**: 支持所有 DDNS 配置参数
+
+### Task 子命令用法
+
+```bash
+# 查看帮助
+ddns task --help
+
+# 检查任务状态
+ddns task --status
+
+# 自动安装（如果未安装）或显示状态（如果已安装）
+ddns task
+
+# 安装定时任务（默认5分钟间隔）
+ddns task --install
+
+# 安装定时任务并指定间隔时间（分钟）
+ddns task --install 10
+ddns task -i 15
+
+# 指定调度器类型安装任务
+ddns task --install 5 --scheduler systemd
+ddns task --install 10 --scheduler cron
+ddns task --install 15 --scheduler auto
+
+# 启用已安装的定时任务
+ddns task --enable
+
+# 禁用已安装的定时任务
+ddns task --disable
+
+# 卸载已安装的定时任务
+ddns task --uninstall
+```
+
+### 支持的调度器
+
+DDNS 会自动检测系统并选择最合适的调度器：
+
+- **Linux**: systemd (优先) 或 cron
+- **macOS**: launchd (优先) 或 cron  
+- **Windows**: schtasks
+
+### 调度器选择说明
+
+| 调度器 | 适用系统 | 描述 | 推荐度 |
+|--------|----------|------|--------|
+| `auto` | 所有系统 | 自动检测系统并选择最佳调度器 | ⭐⭐⭐⭐⭐ |
+| `systemd` | Linux | 现代 Linux 系统的标准定时器，功能完整 | ⭐⭐⭐⭐⭐ |
+| `cron` | Unix-like | 传统 Unix 定时任务，兼容性好 | ⭐⭐⭐⭐ |
+| `launchd` | macOS | macOS 系统原生任务调度器 | ⭐⭐⭐⭐⭐ |
+| `schtasks` | Windows | Windows 任务计划程序 | ⭐⭐⭐⭐⭐ |
+
+### 参数说明
+
+| 参数 | 描述 |
+|------|------|
+| `--status` | 显示定时任务安装状态和运行信息 |
+| `--install [分钟]`, `-i [分钟]` | 安装定时任务，可指定更新间隔（默认5分钟）。**自动覆盖已有任务** |
+| `--uninstall` | 卸载已安装的定时任务 |
+| `--enable` | 启用已安装的定时任务 |
+| `--disable` | 禁用已安装的定时任务 |
+| `--scheduler` | 指定调度器类型，支持：auto、systemd、cron、launchd、schtasks |
+
+> **安装行为说明**:
+>
+> - `--install` 命令直接执行安装，无需事先检查或卸载
+> - 自动替换系统中已有的 DDNS 定时任务
+> - 简化任务管理流程，一键完成任务更新
+
+> **配置参数支持**: `task` 子命令支持所有 DDNS 配置参数，这些参数将被传递给定时任务执行时使用。
+
+### 权限要求
+
+不同调度器需要不同的权限：
+
+- **systemd**: 需要 root 权限 (`sudo`)
+- **cron**: 普通用户权限即可
+- **launchd**: 普通用户权限即可
+- **schtasks**: 需要管理员权限
+
+### 使用示例
+
+```bash
+# 检查当前状态
+ddns task --status
+
+# 安装 10 分钟间隔的定时任务，使用指定配置文件
+ddns task --install 10 -c /etc/ddns/config.json
+
+# 安装定时任务并直接指定 DDNS 参数（无需配置文件）
+ddns task --install 5 --dns cloudflare --id [email protected] --token API_TOKEN --ipv4 example.com
+
+# 安装定时任务，包含高级配置参数
+ddns task --install 10 --dns dnspod --id 12345 --token secret \
+          --ipv4 example.com --ttl 600 --proxy http://proxy:8080 \
+          --log_file /var/log/ddns.log --log_level INFO
+
+# 指定调度器类型安装任务
+ddns task --install 5 --scheduler systemd --dns cloudflare --id [email protected] --token API_TOKEN --ipv4 example.com
+
+# 强制使用 cron 调度器（适用于没有 systemd 的 Linux 系统）
+ddns task --install 10 --scheduler cron -c config.json
+
+# 在 macOS 上强制使用 launchd
+ddns task --install 15 --scheduler launchd --dns dnspod --id 12345 --token secret --ipv4 example.com
+
+# 在 Windows 上使用 schtasks
+ddns task --install 5 --scheduler schtasks --dns cloudflare --id [email protected] --token API_TOKEN --ipv4 example.com
+
+# 在 Linux 上使用 sudo 安装 systemd 定时器
+sudo ddns task --install 5 -c /etc/ddns/config.json
+
+# 更新任务配置（自动覆盖）
+ddns task --install 15 --dns cloudflare --id [email protected] --token NEW_TOKEN --ipv4 example.com
+
+# 启用已安装的任务
+ddns task --enable
+
+# 禁用任务（不删除，仅停止执行）
+ddns task --disable
+
+# 完全卸载定时任务
+ddns task --uninstall
+```
+
+### 与配置文件结合使用
+
+`task` 子命令可以与配置文件完美结合，支持多种配置方式：
+
+```bash
+# 使用本地配置文件
+ddns task --install 10 -c config.json
+
+# 使用多个配置文件
+ddns task --install 5 -c cloudflare.json -c dnspod.json
+
+# 使用远程配置文件
+ddns task --install 15 -c https://config.example.com/ddns.json
+
+# 配置文件 + 命令行参数覆盖
+ddns task --install 10 -c config.json --debug --ttl 300
+
+# 指定调度器类型 + 配置文件
+ddns task --install 5 --scheduler cron -c config.json
+
+# 使用远程配置文件 + 指定调度器
+ddns task --install 10 --scheduler systemd -c https://config.example.com/ddns.json
+```
+
+### 调度器选择指南
+
+根据不同系统和需求选择合适的调度器：
+
+```bash
+# 自动选择（推荐，让系统选择最佳调度器）
+ddns task --install 5 --scheduler auto
+
+# Linux 系统选择
+ddns task --install 5 --scheduler systemd  # 优先选择，功能完整
+ddns task --install 5 --scheduler cron     # 备用选择，兼容性好
+
+# macOS 系统选择
+ddns task --install 5 --scheduler launchd  # 优先选择，系统原生
+ddns task --install 5 --scheduler cron     # 备用选择，兼容性好
+
+# Windows 系统选择
+ddns task --install 5 --scheduler schtasks # 唯一选择，Windows 任务计划
+```
+
+### 调试安装问题
+
+```bash
+# 启用调试模式查看详细安装过程
+ddns task --install 5 --debug
+
+# 查看任务状态和配置
+ddns task --status --debug
+
+# 查看指定调度器的状态
+ddns task --status --scheduler systemd --debug
