Hi experts,
I have a Windows script that is setting the name of a file with extension of date format as yyyymmdd.

It is working but I am wondering how I could modify it to make the date that of yesterday's instead of todays. Here is part of the script

set today=%date:~-4%%date:~4,2%%date:~7,2%
set spt_file_name=SPT.%today%

The command above works to make the file name for example SPT.20071030
I would like it to be SPT.20071029
