Minus 1 day from current date in batch file?

[dfwcharles]

I'm using a batch file to delete files based on the file name. The file name is formatted like this: "log07-14-2004.txt"
I need a way to take the current date in DOS and minus it by one day. Here's what i got so far:

@echo on
set currdate=%date%
set mm=%currdate:~4,2%
set dd=%currdate:~7,2%
set yyyy=%currdate:~10,4%

del C:\testlogs\log%mm%-%dd%-%yyyy%.txt

this works for the current day, but i want to run this everyday to delete the file from the previous day. Is there a way to minus one day from the date?

Thanks

Use VBScript. There are plenty of FAQ's about things like this in the VBScript forum. Besides, .bat's are fine for 98, but you can do so much more with scripts that .bat's.
