what does your system give you when you type:

Code:
date --date="yesterday" '+%Y%m%d'

and/or
Code:
DATE=$(date -d yesterday +"%Y%m%d")
echo $DATE

?

the command
Code:
date

GNU at least on 6.9 works with the --date switch
it might help if you give us the result of:
Code:
man date | grep GNU

hi,

so now you can use as below code...

YDAY=`TZ=MYT+16 date '+%y%m%d%'`
Last edited by sandeep909; 10-06-2009 at 01:03 AM.. Reason: consider TZ as GMT
