1. 危险操作二次确认 删除文件、结束进程、关机/重启、睡眠/休眠等高危操作 执行前需输入 /cmd confirm 二次确认 30 秒超时自动取消，防止误操作
2. PowerShell 危险命令拦截 内置危险命令黑名单（格式化磁盘、删除文件、修改注册表等） 自动拦截高风险 PowerShell 命令，防止误操作或恶意利用
3. 服务端自动禁用 模组仅限客户端使用 在专用服务器上自动禁用，不会产生任何影响
4. 权限要求 需要游戏内 4 级权限（单人需开启作弊，服务器需管理员） 管理员权限命令会触发系统 UAC 弹窗，需手动确认 命令使用 前置要求 需要游戏 4 级权限（单人模式需开启作弊，服务器需为管理员） 仅支持 Windows 系统（Linux/Mac 不支持） 常用命令速览 /cmd help # 查看完整帮助 /cmd exec <命令> # 执行 CMD 命令 /cmd pwsh <命令> # 执行 PowerShell 命令（推荐） /cmd pwsh-admin <命令> # 管理员执行 PowerShell /cmd sysinfo # 系统总览 /cmd cpu # CPU 详情 /cmd gpu # 显卡信息 /cmd ps [关键词] # 进程列表 /cmd ls [路径] # 列目录 /cmd screenshot # 截取屏幕 /cmd volume set 50 # 设置音量 50% /cmd lock # 锁屏 /cmd why # 失败原因分析 /cmd alias add <名> <命> # 添加命令别名 /cmd script run <路径> # 执行脚本文件 /cmd history # 历史记录 /cmd confirm # 确认危险操作 /cmd cancel # 取消待确认操作 /cmd help # 查看完整帮助 /cmd exec <命令> # 执行 CMD 命令 /cmd pwsh <命令> # 执行 PowerShell 命令（推荐） /cmd pwsh-admin <命令> # 管理员执行 PowerShell /cmd sysinfo # 系统总览 /cmd cpu # CPU 详情 /cmd gpu # 显卡信息 /cmd ps [关键词] # 进程列表 /cmd ls [路径] # 列目录 /cmd screenshot # 截取屏幕 /cmd volume set 50 # 设置音量 50% /cmd lock # 锁屏 /cmd why # 失败原因分析 /cmd alias add <名> <命> # 添加命令别名 /cmd script run <路径> # 执行脚本文件 /cmd history # 历史记录 /cmd confirm # 确认危险操作 /cmd cancel # 取消待确认操作 安装方法 安装 Fabric Loader ≥ 0.15.0 和 Fabric API 将 mc2cmd-1.3.jar 放入 .minecraft/mods 文件夹 启动游戏，模组自动加载 注意事项 仅限 Windows 系统：Linux / macOS 暂不支持 UAC 弹窗：管理员权限命令会触发系统 UAC 窗口，需要手动确认 谨慎操作：执行高风险命令前请三思，避免数据丢失 仅限客户端：服务端安装无效，模组会自动禁用 本模组仅供学习和个人使用

Core Features

Dual Command System
CMD Execution: Supports both normal execution and raw execution modes, automatically escaping special characters to prevent errors.
PowerShell Execution: Utilizes EncodedCommand encoding technology to completely resolve issues with Chinese character garbling and special character escaping.
Administrator Privileges: Executes commands as administrator via UAC prompt, supporting PowerShell in admin mode.

System Information Query
Gain full control over your system status—all from within the game:
CPU Details (model, clock speed, physical/logical cores, load)
Graphics Card Info (model, VRAM, current resolution, driver version)
Memory Details (JVM heap memory + total/free system memory)
Disk Space (visualized usage rates across all drives)
Network Information (hostname, IP address, network adapter list)
Process Management (process list, keyword filtering, force termination)

Environment Variables Inquiry
Network Connectivity Testing (ping) File Management Direct local file operations within the game:
Directory browsing (list view with folder/file icons)
File content viewing (with line numbers displayed)
File writing and creation
Directory creation
File/directory deletion (requires secondary confirmation)
File search (supports deep traversal and keyword matching)

Utility Toolbox
Screenshot: Capture main screen with one click and auto-save
Lock screen: Quickly lock your computer screen
Sleep/Hibernate: One-click sleep or hibernate mode (requires confirmation)
Volume control: View and adjust system volume, mute instantly
Clipboard: Copy text to system clipboard quickly
Open file/webpage: Directly open local files or launch browser to access web pages
Scheduled shutdown/restart: Supports custom countdown, can be canceled at any time

Command Alias System
Save frequently used complex commands as short aliases
Aliases are persistently saved—no data loss after game restart
Supports full operations: add, delete, list, execute

Script Execution
Run .ps1 PowerShell scripts directly
Run .bat / .cmd batch scripts directly
Automatically detects script type and provides a unified execution interface

Output Saving
Command execution results can be saved directly as text files
Supports saving output from both CMD and PowerShell commands
Automatically saves to mc2cmd_output directory

Smart Failure Analysis
After command failure, enter /cmd why to get detailed analysis
Automatically identifies common error types: command not found, insufficient permissions, path errors, encoding issues, network problems, etc.
Provides specific solution recommendations for each error type

Command History
Automatically records the last 50 executed commands
Supports searching history by keywords
Quickly review and reuse previous commands

Security Mechanisms

1. Double Confirmation for High-Risk Operations
   High-risk actions such as file deletion, process termination, shutdown/restart, sleep/hibernate require /cmd confirm before execution
   30-second timeout automatically cancels operation to prevent accidental execution

2. PowerShell Risk Command Blocking
   Built-in blacklist of dangerous commands (e.g., disk formatting, file deletion, registry modification)
   Automatically blocks high-risk PowerShell commands to prevent accidents or malicious use

3. Server-Side Auto-Disable
   Mod is client-only
   Automatically disabled on dedicated servers with no impact

4. Permission Requirements
   Requires level 4 in-game permissions (cheats enabled in single-player, admin status required on server)
   Administrator-level commands trigger UAC pop-up requiring manual confirmation

Command Usage
Prerequisites
Level 4 in-game permissions required (cheats enabled in single-player, admin on server)
Windows only (Linux/Mac unsupported)
