a script to match 2 ip strings

nass · 05-30-2007, 03:06 PM

hello everyone,
shouldn't this script return true if the ip addresses match?

Code:

#!/bin/bash

TESTIP=192.168.0.1
echo "=$TESTIP"
HOSTIP=`host synthnassizer.no-ip.org | grep -Eo \([0-9]\{1,3\}.\)\{3\}[0-9]\{1,3
\}`
echo "=$HOSTIP"
if [ TESTIP = HOSTIP ]; then
        echo "they are the same"
else
        echo "they are different"
fi

it always returns 'they are different' to me even though echoing them makes them look alike...
thank you for your help

Bah, just saw it:

Code:

if [ TESTIP = HOSTIP ]; then

should be

Code:

if [ $TESTIP = $HOSTIP ]; then

Common mistake, I make it all the time
