hey shamrock if i wanted to use your code from above and exclude blank lines as well as lines with # at the beginning how would i add that functionality?

For all those interested I ended up going with a code that looks like this:

I added the egrep to filter out any blank or commented lines. This way is so much faster than my original post. Thanks shamrock.

Code:
#check CENTRAL for duplicate ips or hostnames#
        centcheck=`egrep -v '^#|^$' $CENTRAL | $AWK -v me=$ME '{
                ip[$1]++
                h[$2]++
                } END {
                for(i in ip) if(ip[i]>1) print me ":Duplicate IP in hosts.central " i
                for(j in h) if(h[j]>1) print me ":Duplicate hostname in hosts.central " j
                }'`
        if [ "$centcheck" != "" ]
        then
                echo "$centcheck"
                error=true
        fi
