以下脚本未通过crontab运行。请告诉我解决此问题需要哪个步骤。当我手动触发时，此脚本运行正常。

Crontab： - 

### Repack Restart

编辑： cron在服务器定义的时区上运行。您需要检查您的服务器时区，然后设置自己的cron。假设您的服务器时区是GMT：

double a; double b; while (fin_average >> a && fin_rainFall >> b){ fout <<"\t" << (a-b) << endl; }

cron格式如下：

33 01 * * 1-5 command-to-be-executed

检查更多cron格式示例here

请提供有关cron运行脚本的频率的更多信息，然后我们可以帮助确定输出应该是什么样的。

与命令行中运行的作业不同的cron作业的问题源于这样一个事实：环境以不同的方式设置。

错误消息表明，pgrep在某处使用不正确的用户名调用，可能是因为缺少环境变量。由于您要发布的代码中没有~repackpr/server，我想这是在您的cron作业调用的某个脚本中调用的，该脚本必须是/apps/repack/jetty/start.sh或pgrep。尝试找到<script type="text/javascript" src="//code.jquery.com/jquery-migrate-1.2.1.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#frmCalc input:button").on("click", function() { var par = $(this).val(); $("#result").val($("#result").val() + par); }); }); </script> <form action="calculator.php" id="frmCalc" method="POST"> <input type="text" name="result" id="result"> <br> <input type="button" name="one" value="1"> <input type="button" name="two" value="2"> <input type="button" name="three" value="3"> <input type="button" name="four" value="4"> <input type="button" name="five" value="5"> <input type="button" name="six" value="6"> <input type="button" name="seven" value="7"> <input type="button" name="eight" value="8"> <input type="button" name="nine" value="9"> <input type="button" name="0" value="0"> <input type="button" name="+" value="+"> <input type="button" name="-" value="-"> <input type="button" name="*" value="*"> </form> 被调用的地方，并从那里向后工作。
