Could somebody provide a command to use the date command and subtract 1 day from current date. I want to create a script to grab a log file that uses the date as filename. For example, today I manually copied log filename 20070117, tomorrow I need to grab log filename 20070118.

Additionally if anyone could provide pointers on how I can use the date output filename from the above command in my script. I think I have research a way to complete the rest of the script.

Thanks for your input.
