Now what i want is that somehow i only get responce code line ( which i have set as italic ) between certain time stamps like since yesterdays 04:00 pm till todays 03:00 AM

i have tried something like this

function while_read_LINE
{
cat $FILENAME | while read LINE
do
find "RESPONCE" $LINE > responce.txt
:
done
}

but i donno how to cater time stamp

Regards and Thanks
