I need to calculate the Yesterday's date and received a good code from Unix forum. I need to assign the yesterdays Date (MONTH and DATE eg. 1229 for Dec 29)to a Variable ,say myvar. $myvar can be used in any where of the program after that !
#!/bin/ksh GetDate () { set -A DAYS Sat Sun Mon Tue Wed Thu Fri Sat set -A MONTHS Dec Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec YESTERDAY=$((`date +%d` -1)) MONTH=`date +%m` YEAR=`date +%Y` NDAY=`date +%u` WEEKDAY=${DAYS[`date +%u`]} if [ $YESTERDAY -eq "0" ] then MONTH=$((MONTH-1)) if [ $MONTH -eq "0" ] then MONTH=12 YEAR=$((YEAR-1)) fi
set `cal $MONTH $YEAR` shift $(($# - 1)) YESTERDAY=$1 fi TMONTH=${MONTHS[MONTH]} $YEAR echo $MONTH$YESTERDAY return 0 }
