通过java代码执行Linux命令查询声卡和显卡 型号

package test;

import java.io.BufferedReader;

public class ExcuteLinux {

    public static String exeCmd(String commandStr) {

        String result = null;
        try {
            String[] cmd = new String[]{"/bin/sh", "-c",commandStr};
            Process ps = Runtime.getRuntime().exec(cmd);

            BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream()));
            StringBuffer sb = new StringBuffer();
            String line;
            while ((line = br.readLine()) != null) {
                //执行结果加上回车
                sb.append(line).append("\n");
            }
            result = sb.toString();

        } catch (Exception e) {
            e.printStackTrace();
        }

        return result;
    }
    
    public static void main(String[] args) {
　　　　　//查询显卡型号，传入参数为需要执行的命令
        String result = ExcuteLinux.exeCmd("lspci  | grep -i vga");
　　　　　//查询声卡型号
        String result1 = ExcuteLinux.exeCmd("lspci  | grep -i audio");
    }
