JAVA利用Runtime执行多条linux命令

public static void execPythonShell(File file) throws IOException {
  String path = Utils.class.getClassLoader().getResource(“/import.py”)
    .getPath();
  Runtime runtime = Runtime.getRuntime();
  BufferedReader br = null;
  try {
   String[] cmds = new String[] {
     "/bin/sh",
     "-c",
     "cd " + path + "&&python edit_support_export_infor.py "
       + file.getPath() };
   Process process = runtime.exec(cmds);
   br = new BufferedReader(new InputStreamReader(
     process.getInputStream(), "GBK"));
   String tmp = null;
   while ((tmp = br.readLine()) != null) {
    System.out.println("Shell Message : " + tmp);
   }
  } catch (IOException e) {
   logger.error(e);
  } finally {
   br.close();
  }
 }

// -c 意思是执行完成自动关闭，这里多条linux命令通过&&连接到一起
