如何添加日期和时间，在DOS下文件名？ [英] How to add date and time to filename in DOS?

问题描述

我要在文件名添加日期和时间值，然后我想通过文件夹，该文件移动到附近。

I want to add date and time value in filename and then I want to move that file to near by folder.

下面我用下面的命令来捕获日期和时间：

Here I'm using below commands to capture date and time :

set dt=%date:~7,2%-%date:~4,2%-%date:~10,4%_%time:~,8%

echo %dt%

然后我使用copy命令如下：

Then I am using copy command as below :

copy result_accnum.txt C:\ramki_windows\batch_practise\Query_stored\result_accnum_%dt%.txt

但没有用。我得到的错误是文件名，目录名或卷标签语法不正确。

but nothing useful. I am getting error as "The filename, directory name, or volume label syntax is incorrect.".

推荐答案

冒号（：）是不允许的文件名。它保留划定的驱动器盘符等，在DOS路径名。你可以使用下划线（ _ ），而不是：

The colon (:) isn't allowed in a file name. It's reserved for delimiting drive letters, etc, in DOS path names. You could use underscore (_) instead:

set dt=%date:~7,2%-%date:~4,2%-%date:~10,4%_%time:~0,2%_%time:~3,2%_%time:~6,2%

请注意，没有前导零的时间上午10点之前。如果这是你的文件名的格式重要，那么它可以做如下：

Note that there is no leading zero for times before 10 am. If this is important for your file name format, then it could be done as follows:

set hh=%time:~0,2%
if "%time:~0,1%"==" " set hh=0%hh:~1,1%   

set dt=%date:~7,2%-%date:~4,2%-%date:~10,4%_%hh%_%time:~3,2%_%time:~6,2%
