Hi Panyam,

i don't think the issue is with grep, as i am getting the data if the else part of the code is executed.
The only issue is with first part of the code which i am using to get the yesterday's data, if the current time is less than 5 am.(as i njeed to get 5 hrs back data)
The first part also is printing the $ express correctly. There should an issue with the space somewhere which is causing ultimately grep not to pick any data.

Code:
if (( $stime < 5 ))
then
stime=`expr $stime \+ 18`
export express=`TZ=CST+24 date '+%m/%d/%Y'`\ $stime
