Here is a way:

First get the previous two days

Code:
# suppose today is 20080229 (date + %Y%m%d)
# then to get two days before you can write

yesterday1=`TZ=$TZ+24 date +%Y%m%d`
yesterday2=`TZ=$TZ+48 date +%Y%m%d`

# Then yesterday1 = 20080228  yesterday2 = 20080227

now you can perform a lot of things like
Code:
cp XX_${yesterday1}*.zip 1.zip
cp XX_${yesterday2}*.zip 2.zip

rm XX*

mv 1.zip XX_${yesterday1}*.zip
mv 2.zip XX_${yesterday2}*.zip


hope you get the point Smilie
