Thank you so much for that, But the problem is. It removes the (.) and then sorts it, Fine till there.

Quote:
1.2.3.9
1.2.3.4
1.2.3.11
1.2.3.10
1.0.0.1

This should do

Code:
#! /bin/sh

maxversion=$(sed 's/\.//g' ver.txt | sort -n | tail -1)

echo $maxversion

while read line
do
        [ "${line//\./}" -eq "$maxversion" ] && echo "$line" && exit 0
done < ver.txt

Uses a sh only sed like construct.

A non-sed non-tail non-sort solution

Code:
#! /bin/sh
BASE=0

while read line
do
        VER=${line//\./}
        [ $VER -ge $BASE ] && BASE=$VER && high=$line
done < ver.txt
echo $high
