"d:\Program Files\7-Zip\7z.exe" a -r code_%date:~10,4%-%date:~4,2%-%date:~7,2%.zip

我也遇到过类似的问题。我每天都会从FTP服务器上自动下载一个加密文件。我想使用gpg解密文件，将文件重命名为当前日期(YYYYMMDD格式)，并将解密文件放入正确部门的文件夹中。

我根据日期查看了几个重命名文件的建议，直到我偶然发现了这个简单的解决方案。

for /f "tokens=1-5 delims=/ " %%d in ("%date%") do rename "decrypted.txt" %%g-%%e-%%f.txt

它工作得很好(例如，文件名显示为“2011-06-14.txt”)。

就用这句话:

PowerShell -Command "get-date"

在Windows 7中，这段代码适用于我:

SET DATE=%date%
SET YEAR=%DATE:~0,4%
SET MONTH=%DATE:~5,2%
SET DAY=%DATE:~8,2%
ECHO %YEAR%
ECHO %MONTH%
ECHO %DAY%

SET DATE_FRM=%YEAR%-%MONTH%-%DAY% 
ECHO %DATE_FRM%
