RE: OT: shell script to compare nos.

But this does not work for real numbers, ex: 2.51 ot 2.01, it compares only integers

Why not simply do the following passing two parameters to the script eg. call the script test.sh and call it so

test.sh 2 1

This results in output "VAR1 is greater than VAR2"

then

test.sh 1 2

this results in output "VAR2 is greater than VAR1"

Cheers.

#!/bin/ksh
VAR1=$1
VAR2=$2
if [ "$VAR1" -gt "$VAR2" ]
then
echo "VAR1 is greater than VAR2"
else
echo "VAR2 is greater than VAR1"
fi

Hi
I'm sure there are better ways but awk does the trick

echo $var1 $var2 | awk '{ if ( $1 > $2 ) { print "1"} else { print"0" } }'

cheers alex
