Hi SIFA,you try the following script to do your task.

Code:
i=0
while read line
do
arr[$i]=`echo $line | cut -d ' ' -f 1`
let i+=1
done < input

val=0
for((j=0;j<$i;j++))
do
if [[ ${arr[$j]} -gt $val ]];then
val=${arr[$j]}
fi
done

sed -rn "s/${val} (.*)/\1/p" input

In my code,input is the input file which contains the input as you described in your question.
