一个嵌入fio依赖的golang库(A golang library with embedded fio dependencies)

这个库提供了对FIO存储性能基准测试工具的Go语言封装。FIO是一个用于测试存储设备性能的综合性基准测试工具，可以测试磁盘的IOPS、带宽和延迟等关键性能指标。

This library provides a Go wrapper for the FIO storage performance benchmark tool. FIO is a comprehensive benchmark tool for testing storage device performance, capable of measuring key performance metrics such as IOPS, bandwidth, and latency of disks.

• 支持多平台：Linux (amd64, arm64, 386, arm等), macOS (amd64, arm64), Windows (amd64, 386), FreeBSD (amd64)
• 自动检测并使用系统安装的fio，或使用嵌入的二进制文件
• 自动清理临时文件
• 支持root权限检测和sudo执行
• Multi-platform support: Linux (amd64, arm64, 386, arm, etc.), macOS (amd64, arm64), Windows (amd64, 386), FreeBSD (amd64)
• Automatically detects and uses system-installed fio, or uses embedded binaries
• Automatic cleanup of temporary files
• Support for root permission detection and sudo execution

获取可用的fio命令路径。该函数会首先尝试使用系统安装的fio，如果没有找到则使用嵌入的二进制文件。

Get the available fio command path. This function will first try to use the system-installed fio, and if not found, it will use the embedded binary.

返回值 Returns:

• string: fio命令的路径或命令字符串 (Path to the fio command or command string)
• string: 临时文件路径（如果使用了嵌入的二进制文件）(Temporary file path if using embedded binary)
• error: 错误信息 (Error information)

执行逻辑 Execution Logic:

1. 检查系统是否已安装fio
2. 如果有root权限，优先尝试sudo fio
3. 尝试直接运行fio
4. 如果系统没有fio，则提取嵌入的二进制文件到临时目录

执行fio命令。

Execute the fio command.

参数 Parameters:

• fioCmd: fio命令的路径或字符串 (Path or string for the fio command)
• args: 传递给fio的参数 (Arguments to pass to fio)

清理临时文件。

Clean up temporary files.

参数 Parameters:

• tempFile: 需要清理的临时文件路径 (Path to temporary file to clean up)
