調用shell指令碼，判斷是否正常執行，如果正常結束，Process的waitFor()方法返回0

public static void callShell(String shellString) {      try {          Process process = Runtime.getRuntime().exec(shellString);          int exitValue = process.waitFor();          if (0 != exitValue) {              log.error("call shell failed. error code is :" + exitValue);          }      } catch (Throwable e) {          log.error("call shell failed. " + e);      }  }
