How do I add X days to date and get new date?

I need to add/calculate 10 days plus date so then I will get new date (expiration date))

for example

# date 

 Sun Sep 11 07:59:16 IST 2012

So I need to get

NEW_expration_DATE = Sun Sep 21 07:59:16 IST 2012

Please advice how to calculate the new expiration date ( with bash , ksh , or manipulate date command ?)

shell-script bash linux

You can just use the -d switch and provide a date to be calculated

date

Sun Sep 23 08:19:56 BST 2012

NEW_expration_DATE=$(date -d "+10 days")

echo $NEW_expration_DATE

Wed Oct 3 08:12:33 BST 2012

This is quite a powerful tool as you can do things like

date -d "Sun Sep 11 07:59:16 IST 2012+10 days"

Fri Sep 21 03:29:16 BST 2012
