extracting characters from file name

[mbourgeault]

I am looking for a way to extract a 2 digit year and 2 digit month that is in a file name and save them off to a text file named 'test<2digityear><2digitmonth>.txt'.

ie: test0905.txt

want to extract the 0905 and store is as the content of LoadDate.txt

Any help would be greatly appreciated
Thank you

Your post is confusing. Is testYYMM.txt always the filename that you want to extract the YYMM from? Then:

Code: Select all

set filename=test0905.txt
:: Or you could pass the filename with set filename=%~1
:: Or you could do a for loop and then set filename=%%~a
:: with the for loop you'll have to use enabledelayedexpansion
set year=%filename:~4,2%
set month=%filename:~6,2%

:: or like this
echo.%filename:~4,4%>loaddate.txt

If that's not what you mean, then please elaborate.
