Could this help you ?
Code:
paste - - < Filename| while read line
do
dt2=$(echo $line | awk '{print $4" "$5}')
dt1=$(echo $line | awk '{print $1" "$2}')
echo -n $(echo $line | awk '{print $4,$5","$1,$2","$3","}')
echo $(($(date -d"$dt2" '+%s') - $(date -d"$dt1" '+%s')))
done

Hi Pravin,

Thanks much for your quick response. I'm receiving the following errors, when executing this code :
Code:
$ transpose.log | while read line
> do
> (dt2=$(echo $line | awk '{print $4" "$5}')
> dt1=$(echo $line | awk '{print $1" "$2}')
> echo -n $(echo $line | awk '{print $4,$5","$1,$2","$3","}')
> echo $(($(date -d"$dt2" '+%s') - $(date -d"$dt1" '+%s')))
> done
ksh: 0403-057 Syntax error: `done' is not expected.

Thanks,
NK
