hi

i am having a script in which i am supposed to extract data for three different dates...first date is current date
second date is 15 days back
third date is 40 days back

for eg consider todays date 26062006 as first date then
second date is 11062006
third date is 17052006

now in my script i can get first date using date command. but for second & third date i need to give values manually.due to this i am not able to automate my script. resently i got following commands...

NOW_DATE=$(date)
DATE_15=$(perl -e 'print scalar localtime(time-1296000)')
DATE_40=$(perl -e 'print scalar localtime(time-3456000)')

they do work but the problem in them is that format of month is in alphabets... i.e. month come as Aug or Sep.. etc....
where as i req it in numerical format as 08 or 09 etc ...

Thanks in advance
