java执行shell或者cmd命令

Shell: http://blog.csdn.net/bhq2010/article/details/7414788
Java执行Linux命令并返回命令结果 http://blog.csdn.net/jiafu1115/article/details/6941245
使用Java中的Runtime.exec()执行Windows命令 http://walsh.iteye.com/blog/449051

Java 可以通过 Runtime 调用Linux命令，形式如下：
Runtime.getRuntime().exec(command)
但是这样执行时没有任何输出，因为调用 Runtime.exec 方法将产生一个本地的进程，并返回一个Process子类的实例（注意：Runtime.getRuntime().exec（command）返回的是一个Process类的实例）该实例可用于控制进程或取得进程的相关信息。
由于调用 Runtime.exec 方法所创建的子进程没有自己的终端或控制台，因此该子进程的标准IO（如stdin,stdou,stderr）都通过 Process.getOutputStream()，Process.getInputStream()， Process.getErrorStream() 方法重定向给它的父进程了。

/**

	 * @param shell 需要运行的shell脚本

	public static void execShell(String shell){
		try {
			Runtime rt = Runtime.getRuntime();
			rt.exec(shell);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}


/**
	 * 运行shell
	 * 
	 * @param shStr
	 *            需要执行的shell
	 * @return
	 * @throws IOException
	 */
	public static List runShell(String shStr) throws Exception {
		List<String> strList = new ArrayList();

		Process process;
		process = Runtime.getRuntime().exec(new String[]{"/bin/sh","-c",shStr},null,null);
		InputStreamReader ir = new InputStreamReader(process
				.getInputStream());
		LineNumberReader input = new LineNumberReader(ir);
		String line;
		process.waitFor();
		while ((line = input.readLine()) != null){
		    strList.add(line);
		}
		
		return strList;
	}
