Question

使用Windows批处理代码

，需要一些帮助才能找到上一年

我正在使用的代码是

:: This is Code for D3
@echo off
set day=-1
echo >"%temp%\%~n0.vbs" s=DateAdd("d",%day%,now) : d=weekday(s)
echo>>"%temp%\%~n0.vbs" WScript.Echo year(s)^& right(100+month(s),2)^& 
right(100+day(s),2)
for /f %%a in ('cscript /nologo "%temp%\%~n0.vbs"') do set "result=%%a"
del "%temp%\%~n0.vbs"
set "YYYY=%result:~0,4%"
SET "PREVYEAR=%result:~0,4%-%1%"
set "MM=%result:~4,2%"
set "DD=%result:~6,2%"
SET YEAR=%DATE:~-4%
set "filename=%mm%%dd%%yyyy%"
echo "E:\Data Loads Folder\SafetyAndSecurity\D3\QVD\*%YYYY%_%filename%.QVD"
echo "E:\Data Loads Folder\SafetyAndSecurity\D3\QVD\*%PREVYEAR%_%filename%.QVD"
pause

这给出了输出

"E:\Data Loads Folder\SafetyAndSecurity\D3\QVD\*2017_11152017.QVD"
"E:\Data Loads Folder\SafetyAndSecurity\D3\QVD\*2017-_11152017.QVD"

我需要一些建议如何找到前一年，变量PREVYEAR的输出应该是2016

Answer 1

根本不需要Vbscript。虽然它确实有帮助，甚至Powershell也是一个好主意，你可以用WMIC和Batch完成所有这些。

@echo off

REM Get Date and Time regardless of regional setttings
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"

REM Set year month and day into its own variables.
set "yyyy=%dt:~0,4%"
set "mm=%dt:~4,2%"
set "dd=%dt:~6,2%"

REM Subtract year
set /a "yyyy-=1"

Answer 2

您可以使用一行批处理

执行此操作

将PREVYEAR设为2016年

与Squashman不同，我不喜欢Powershell，请看一下Ruby替换vbscript。

在Ruby中，这将是

set /a "PREVYEAR=%date:~9,4%-1"
