java RunTime.getRuntime.exec()使用外部命令，特殊字符

这样一段java代码：

        // 最初的
	/*private static final String FILE_COMMAND_WIN = "file.exe %s";
	private static final String FILE_COMMAND_LINUX = "file %s";*/
        // 最终的
	private static final String FILE_COMMAND_WIN = "file.exe";
	private static final String FILE_COMMAND_LINUX = "file"

	public static String getFileCommandResult(String file) throws IOException {
		Process process = null;	
		InputStream in = null;
		InputStreamReader reader = null;
		BufferedReader bufferedReader = null;
		String result = null;
		try {
			String command;
			if (Util.isWindows())
				command = FILE_COMMAND_WIN;
			else
				command = FILE_COMMAND_LINUX;
                        
        //(0)最初的设计，不能解决file中特殊字符的问题，path和文件名字有空格或特殊字符，程序会在这里hang住
        //process = Runtime.getRuntime().exec(String.format(command, file));
                        
        //(1)这样程序不会hang住，但是shell命令提示找不到这个文件
			/*File oldFile = new File(file);
			String temp = oldFile.toURI().getRawPath();
			System.out.println(temp);*/
        //(2)这样程序程序也会hang住
			/*String temp = file.replace(" ", "\" \"");
			System.out.println(temp);
			process = Runtime.getRuntime().exec(String.format(command, temp));*/
		        
        //最终的。exec的重载输入可以是个字符数组
        //将命令和参数分开，避免exec自己以空格去划分。
			String[] commands = new String[2];
			commands[0] = command;
			commands[1] = file;
			//System.out.println(commands.toString());
			process = Runtime.getRuntime().exec(commands);
			in = process.getInputStream();
			reader = new InputStreamReader(in);
			bufferedReader = new BufferedReader(reader);
			result = bufferedReader.readLine();
		} finally {					
			if (bufferedReader != null)
				bufferedReader.close();
			
			if (process != null)
				process.destroy();
		}
		
		return result;
	}
