Hi,
There are already some scripts posted in this forum reg date manipulations.This one is a addition to that.Go thro this script..
I didn't do any error checking (assuming that could be done in ano script)
# **** Finding date for a day after ****
#Add 1 to month, set date to 1 for the foll:
#if the date is 31
#if the date is 30, if the months are Apr, July, Sep or Nov
#if the date is 29, month is feb
#if the date is 29, month is feb and the year is leap year
#After addition, if the month is 13
#add 1 to year, set month to 1
#supply your date here
echo "28 02 4000"|
{
read DATE MONTH YEAR
incrementdate()
{
DATE=01
MONTH=`expr $MONTH + 1`
}
#check for date
case $DATE in
31)
incrementdate
;;
30)
if [ $MONTH -eq '04' -o $MONTH -eq '06' -o $MONTH -eq '09' -o $MONTH -eq '11' ]
then
incrementdate
fi
;;
29)
if [ $MONTH -eq '02' ]
then
incrementdate
fi
;;
28)
leapyr=`expr $YEAR % 4`
if [ $MONTH -eq '02' -a $leapyr -eq '0' ]
then
incrementdate
fi
;;
*)
DATE=`expr $DATE + 1`
;;
esac
#check for month
case $MONTH in
13)
#due to the above additions
MONTH=1
YEAR=`expr $YEAR + 1`
;;
esac
echo $DATE $MONTH $YEAR
}
