UNIX for Dummies Questions & Answers

i need help! can someone help me please?
i try to calculate date under unix (ksh)...AIX operating system.

I have to find the date 200 days from today's date.
then the script should loop 200 times and display on command line every day's date until the current date.


example:

todays date: 2009-08-12
(calculate date 5 days from current date and loop and display until the date is current date)

Display:

2009-08-07
2009-08-08
2009-08-09
2009-08-10
2009-08-11

how can i do calculate?
i know that it is not possible with the date command!

Thanks in advance
Mark
