Hi ,
This is from one post in other shell group .. I forgot who is the poster.

#! /bin/sh

	year=`date +%Y`
	month=`date +%m`
	day=`date +%d`



	# figure out what yesterday was.



	day=`expr "$day" - 1`

	case "$day" in
	0)
		month=`expr "$month" - 1`
		case "$month" in
		0)
			month=12
			year=`expr "$year" - 1`
			;;
		esac



	# figure out the last day of the month

# day=`cal $month $year | grep . | fmt -1 | tail -1`

    :$(cal $month $year)
    day = $_
    ;;

        esac

        echo "$year$month$day"
