bat date 取年时，只取到周

备份数据库文件时，发现备份生成的文件名为 【vipsoft_周三】，发现是系统的日期格式问题。需调整日期格式，生成 【vipsoft_20220601.sql】

mysqldump -uroot -p110 vipsoft > D:\DBBackup\MySQL\vipsoft%Date:~0,4%%date:~5,2%%date:~8,2%.sql 

 

C:\Users\Administrator>date
The current date is: 周三 2022/06/01
Enter the new date: (yy-mm-dd)

C:\Users\Administrator>

 

 

 

@echo off


echo 年月日：%Date:~0,4%%date:~5,2%%date:~8,2%

echo 提取年：%Date:~0,4%
echo 提取月：%Date:~5,2%
echo 提取日：%Date:~8,2%
set /a a=%Date:~0,4%+1
echo 年份加1处理：%a%
echo 组装年月日(-号分割)：%a%-%Date:~5,2%-%Date:~8,2%
echo 组装时分秒(,号分割)：%time:~0,2%,%time:~3,2%,%time:~6,2%
