I need to add days to a variable which stores the date.

Eg: If my variable date is 2/19/2009,I need to add 7 days so my output date should be 2/26/2009.

vdt2= $vdt2 + 7 (where $vdt2 is the variable date).

Im having errors when I try the same syntax with the input variable.

vdt2=/opt/freeware/bin/$vdt2 -d "+7 day" +"%D"

Any help?

Thanks,
Sud.

Look at the "--date" option of the date command. (info date). I think you can use that but I couldn't quickly figure out how to get it to take input in mm/dd/yy format.
Code:
date1='2009-02-19 00:00:00 +0000'
date2=$(/opt/freeware/bin/date --date="$date1" -d "+5 day" +"%D")
echo $date2

Thanks for your input hard_aix but
date2=$(/opt/freeware/bin/date --date="$date1" -d "+5 day" +"%D") isnt working,I tried exploring the --date but Im still having issues converting string to the required date format.
Any light here will be greatly appreciated.

Can you copy/paste and post what happens when you execute those 3 lines of code on your system?
