This code was posted here by someone else to determine yesterday:

Code:

#!/usr/bin/ksh
date '+%m %d %Y' | 
{ 
read MONTH DAY YEAR
DAY=`expr "$DAY" - 1` 
case "$DAY" in 
        0) 
           MONTH=`expr "$MONTH" - 1` 
                case "$MONTH" in 
                        0) 
                           MONTH=12 
                           YEAR=`expr "$YEAR" - 1` 
                        ;; 
                esac 
        DAY=`cal $MONTH $YEAR | grep . | fmt -1 | tail -1` 
esac 
echo "Yesterday was: $MONTH $DAY $YEAR" 
}

It can probably be modified to do what you ask,

or use perl method:

print scalar localtime (time() - 86400 * n);
it will substract n from current date and print the date

To get date seven days from now:
print scalar localtime (time() + 86400 * 7);

7 days before current date:
print scalar localtime (time() - 86400 * 7);
