A ksh solution :

Code:

#!/usr/bin/ksh
# Usage: $0 version1 version2

set -o nounset

oIFS="$IFS" ;IFS='.'
set -A v1 $1
set -A v2 $2
IFS="${oIFS}"

cnt1=${#v1[*]}
cnt2=${#v2[*]}
(( cnt1 > cnt2 )) && cnt=$cnt1 || cnt=$cnt2;

i=0
result="EQUAL"
while (( i <= cnt ))
do
    (( n1 = ${v1[$i]-} + 0 ))
    (( n2 = ${v2[$i]-} + 0 ))
    if (( n1 > n2 ))
    then
        result="GREATER"
        break
    elif (( n1 < n2 ))
    then
        result="LOWER"
        break
    fi
    (( i += 1 ))
done

print ${result} $1 $2

Examples:

Code:

$ ./cmpv.ksh 1.2.3 1.2.3
EQUAL 1.2.3 1.2.3
$ ./cmpv.ksh 1.2.4 1.2.3
GREATER 1.2.4 1.2.3
$ ./cmpv.ksh 1.2.4 1.2.4.1
LOWER 1.2.4 1.2.4.1
