在批处理文件进行比较的修改的文件的日期与当前日期 [英] Comparing a modified file date with the current date in a batch file

问题描述

我需要编写一个批处理文件做了几件事情。

I'm required to write a batch file to do a few things

起初我还以为我的问题很简单 - 抓住位于指定目录中的txt文件的修改日期，该日期比较当前日期，如果它们是相同的做一些事情。如果他们不那么做别的事情。

Initially I thought my problem was very simple - capture the modified date of a txt file located in a specified directory, compare that date to the current date and if they are the same do something. If they are not then do something else.

我来捕获当前日期的行是：

The line I use to capture the current date is:

%date%

我来捕获我的指定文件的修改日期的台词是：

The lines I use to capture the modified date of my specified file is:

SET filename="C:\New Folder\New.txt"
FOR %%f IN (%filename%) DO SET filedatetime=%%~tf
ECHO %filedatetime:~0,-6% >> %destination%

在上述情况下，我只需要使用回声来看看有什么被返回，它好像日返回，但我得到额外的信息：

In the above case I'm simply using echo to see what is returned and it seems as if the date is returned but I get extra information:

02 2012/02/19

2012/02/19 02

我想知道如何获得他们在哪里可比上述值，以及如何将它们正确地进行比较。

I would like to know how to get the above values where they are comparable as well as how to compare them properly.

推荐答案

我喜欢 dbenham的的方式，但如果你想您code工作，你可以这样做：

I like dbenham's way, but if you want to make your code work you can do like this:

set currentDate=%date%
SET filename="C:\MyFile.txt"

FOR %%f IN (%filename%) DO SET filedatetime=%%~tf
IF %filedatetime:~0, 10% == %currentDate% goto same

goto notsame

:same
echo Dates the same, do some code here

goto next

:notsame
echo Dates NOT the same, do some code here
goto end

:next

认为这将是值得知道如何使你的情况下，只是工作，你又需要它。

Thought it would be worth knowing how to make yours work just in case you need it again.
