Dear friend
write a few lines in the shell as follows:
bye using date format command store today's date value in variable dt
hence if todays date is 09282001 in mmddyyyy format
dt='09282001'
now store value of dt to a file
echo $dt>file1
now cut value of today's date in variable v1
v1=`cut -c3-4 file1`
now find out value of previous date by using expr command
v2=`expr $v1 -1`
now prepare the full date by replacing 3rd and 4th chr of file1 by value of v1
Of course you will also have to add validations for last date of months and for february also
hope expr command will help you
Wish you all the best
yours friendly
