Thanks for the help. Your pointers certainly have helped made my code run better.

But the real problem I am having is with this part of code

Code:
#Some debug code for a select group of hosts.
echo "-----------------------------------------------------------\n"
echo "DEBUG: VARIABLE (IP) IS: " $IP 
echo "DEBUG: VARIABLE (host) IS: " $host

output="$IP $host\n$output"
done
echo "$output"

Instead of outputting to the terminal on the echo command what is intended I get the following:

Code:
Hostname.10.2

when it should be:

Hostname 192.168.10.2

I have over 600 addresses and host names and it only does this weird output for 8 of them. I want to say its an overflow but I can't convince my self that is what is happening.

Thanks again!
