Answer Posted / md. imran

if [ $# -eq 0 ]
then
echo "$: numbers are not given" >&2
exit 1
fi
LARGEST=$(echo $* |xargs -n1 |sort |head -1)
echo $LARGEST is largest number"

or if you want to take input from a file so type following
cat <filename>|xargs -n1|sort|head -1

Note : In first scipt mistake was in tail -1
right answer is head -1 which i have mentioned there.

thanks
