for循环在Windows批处理中不起作用

Question

I want to execute this in a Windows batch:

for /F %%A In ('PowerShell Get-Date -UFormat %V') do copy "D:\Versand\Test\OrdersOffers.xlsm" "D:\Versand\Test\OrdersOffersWeek%%A.xlsm"

But nothing is happening. It works if I do it in CMD like this:

for /F %A In ('PowerShell Get-Date -UFormat %V') do copy "D:\Versand\Test\NL_OrdersOffers.xlsm" "D:\Versand\Test\NL_OrdersOffers%A.xlsm"

What could be the problem?

Answer 1

 -UFormat %V

becomes

 -UFormat %%V

because % is a special character that needs to be escaped by % itself
