我之前正好做了一个java 调用shell 脚本或者bat脚本的工具类，供楼主参考
为了防止命令进程阻塞，添加两线程处理输出信息

package utils;

	private static Logger logger = Logger.getLogger(CallCmdUtils.class);
	
	public static void executeCmd(String cmd){
		if(cmd == null || cmd.equals("")){
			return;
		}
		logger.info("执行命令："+cmd);

		String[] cmds = new String[]{"/bin/sh","-c",cmd};
		try {
			Runtime.getRuntime().exec(cmds);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

	/**
	 * 执行本地命令 cmd格式 windows 环境下查询360运行exe程序： cmd /c tasklist | findstr
	 * "360.*[.exe]"

	 * @param cmd

	 */
	public static ResponseData executeLocalCmd(String cmd) {
		if(cmd == null || cmd.equals("")){
			return ResponseData.FAIL_NO_DADA;
		}
		logger.info("执行命令："+cmd);

		String[] cmds = new String[]{"/bin/sh","-c",cmd};
		StringBuffer sb = new StringBuffer(255);
		ResponseData data = ResponseData.FAIL_NO_DADA;
		try {
			Process process = Runtime.getRuntime().exec(cmds);
			process.waitFor();
			int  result = process.exitValue();
			if(result == 0){
				data.setSuccess(true);
				InputStream in = process.getInputStream();
				BufferedReader br = new BufferedReader(new InputStreamReader(in));
				String dataline = null;
				while ((dataline = br.readLine()) != null) {
					sb.append(dataline).append("\n");
				}
				br.close();
				in.close();
				data.setResult(sb.toString().trim());
			}else{
				InputStream in = process.getErrorStream();
				BufferedReader br = new BufferedReader(new InputStreamReader(in));
				String dataline = null;
				while ((dataline = br.readLine()) != null) {
					sb.append(dataline).append("\n");
				}
				br.close();
				in.close();
				data.setErrorMsg(sb.toString().trim());
			}
			
		} catch (Exception e) {
			e.printStackTrace();
		}
		return data;
	}

貌似有个开源的框架可以实现类似的功能，名字我不记得了，你可以查一下

可以的， 给你一个简单的ping google的吧

import java.io.BufferedReader;
import java.io.InputStreamReader;
 
public class ExecuteShellComand {
 
	public static void main(String[] args) {
 
		ExecuteShellComand obj = new ExecuteShellComand();
 
		String domainName = "google.com";
 
		String command = "ping -c 3 " + domainName;
 
 
		String output = obj.executeCommand(command);
 
		System.out.println(output);
 
	}
 
	private String executeCommand(String command) {
 
		StringBuffer output = new StringBuffer();
 
		Process p;
		try {
			p = Runtime.getRuntime().exec(command);
			p.waitFor();
			BufferedReader reader = 
                            new BufferedReader(new InputStreamReader(p.getInputStream()));
 
                        String line = "";			
			while ((line = reader.readLine())!= null) {
				output.append(line + "\n");
			}
 
		} catch (Exception e) {
			e.printStackTrace();
		}
 
		return output.toString();
 
	}
 
}
