### name : greater_of_2_numbers.ksh

#! /bin/ksh

### If you won't supply 2 numbers then it will prompt you to 2 numbers. ###

if [ $# -ne 2 ] ($# : number of positional parameters)
then
echo "Usage: $0 <Enter 2 numbers>" ($0 : name of script)

then
echo "$2 is greater than $1"
else
echo "Two numbers are equal"
fi
