Windows批处理脚本：在日志中显示日期、时间和所有输出

windowsdateloggingtimebatch-file
3

我制作了一个脚本，将使用Windows计划任务程序来备份我创建的Ruby on Rails应用程序。

当我在命令窗口正常调用该命令时，输出如下：

C:\Users\admin\Desktop\app>heroku db:pull --confirm app

以下是我的 .bat 文件：

heroku db:pull --confirm app >> log.txt

如果我运行两次，这就是输出结果，会被写入到一个名为log.txt的文件中。

有没有办法包含精确的控制台输出，并包括脚本运行的日期和时间？提前感谢。

使用%date%和%time%很容易添加日期和时间。

您可以尝试将stderr（2）重定向到stdout（&1），也许这样就能捕获缺失的输出。

echo Start: %date% %time% >>log.txt
heroku db:pull --confirm app >>log.txt 2>&1
echo Stop: %date% %time% >>log.txt
谢谢您的帮助，似乎仍然存在一些问题。请查看更新。 - user1720381
不太清楚如何解释出现了什么问题，但我认为这只是日志文件格式的问题。你能看到有什么方法可以修复它吗？ - user1720381
@Jamie - 看起来 heroku 在将状态信息打印到 stderr 时会修改屏幕上的位置。我认为如果不付出荒谬的努力，就无法获得好看的日志。我建议保留丑陋的日志，或者回到没有 stderr 的原始日志。如果绝对必要，您可以将 stderr 重定向到另一个文件，然后从中处理和提取所需信息，然后附加到常规日志中，但我不知道您需要什么。根据您尝试提取的内容，这可能会很棘手。 - dbenham
好的，谢谢。我可能会回到我的旧日志，但会包括日期。感谢您的帮助。 - user1720381
