如何在batch file中获取昨天的date

我知道如何在Windows 7中获得今天的date。下面是我正在使用的命令:

%DATE:~6,4%%DATE:~3,2%%DATE:~0,2% 

但是我想得到昨天,我不知道如何。

如果你只限于cmd.exe ,那么其他解决方案,尽管它们的大小,可能是你会得到的好。 但是,现代Windows(例如Win7)附带了很多其他工具,可以使工作变得更容易。

只需按如下所示创建一个VBScript yester.vbs脚本:

 d = date() - 1 wscript.echo year(d) * 10000 + month(d) * 100 + day(d) 

然后你可以从你的cmd脚本中调用它:

 for /f %%a in ('cscript //nologo yester.vbs') do set yesterday=%%a 

yesterday变量将以yyyymmdd的形式创建,供您操作,但是您的愿望。

找到一个脚本,将确保您获得前一天即使年份或月份更改昨天批次 。

这里有一个解决方案,可以即时创建earlierday.vbs文件,然后使用它并删除它。

它将结果存储在NewDate变量中

此示例计算1天前,但可以通过更改Offset变量的值来轻松计算日期。

 @echo off set Offset=1 echo d = date() - WScript.Arguments.Item(0) > earlierday.vbs echo wscript.echo year(d) * 10000 + month(d) * 100 + day(d) >> earlierday.vbs for /f %%a in ('cscript //nologo earlierday.vbs %Offset%') do set NewDate=%%a del earlierday.vbs echo %NewDate% pause 

您可以通过使用%temp%\ earlierday.vbs来稍微改善这一点,以在用户的​​临时文件夹中创建该文件。

感谢paxdiablo,因为这是对他之前发表的一个简单的调整。

编辑:这是一个循环的东西,接近我真正需要它做的。 这将需要14天的日期,并返回该日期。 然后它会一直保持7天,直到一天到达35天。

 @echo off SETLOCAL EnableDelayedExpansion set BackDaysFrom=14 Set BackDaysTo=35 Set BackDaysStep=7 echo d = date() - WScript.Arguments.Item(0) > earlierday.vbs echo wscript.echo year(d) * 10000 + month(d) * 100 + day(d) >> earlierday.vbs for /L %%i in (%BackDaysFrom%, %BackDaysStep%, %BackDaysTo%) do ( for /f %%a in ('cscript //nologo earlierday.vbs %%i') do set NewDate=%%a echo !NewDate! ) del earlierday.vbs pause
