Need to pull Yesterdays Date...
I tried this and it works for the most part, but if the date is 20090301, it displays 20090300.

YESTERDAY=$((`date +%Y%m%d` -1))

Hammer & Screwdriver Here is a section of code I use to find a previous date
All of the following may not be needed for what you are doing, but commands are such that I can modify DAYS to set a variable CUTOFF so I can match on records.

Code:
> touch file005            
> DAYS=1
> FT=`stat -c %Z file005`
> DT=`echo ${DAYS}*24*60*60 | bc`
> PT=`echo $FT - $DT | bc`
> CUTOFF=`echo $(date '+%Y%m%d' -d @$PT)`
> echo $CUTOFF
20090303
