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

SPLIT(1) User Commands SPLIT(1)NAME
split - split a file into pieces
SYNOPSIS
split [OPTION]... [INPUT [PREFIX]]
DESCRIPTION
Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, ...; default size is 1000 lines, and default PREFIX is 'x'. With no INPUT, or
when INPUT is -, read standard input.
Mandatory arguments to long options are mandatory for short options too.
-a, --suffix-length=N
generate suffixes of length N (default 2)
--additional-suffix=SUFFIX
append an additional SUFFIX to file names
-b, --bytes=SIZE
put SIZE bytes per output file
-C, --line-bytes=SIZE
put at most SIZE bytes of lines per output file
-d, --numeric-suffixes[=FROM]
use numeric suffixes instead of alphabetic; FROM changes the start value (default 0)
-e, --elide-empty-files
do not generate empty output files with '-n'
--filter=COMMAND
write to shell COMMAND; file name is $FILE
-l, --lines=NUMBER
put NUMBER lines per output file
-n, --number=CHUNKS
generate CHUNKS output files; see explanation below
-u, --unbuffered
immediately copy input to output with '-n r/...'
--verbose
print a diagnostic just before each output file is opened
--help display this help and exit
--version
output version information and exit
SIZE is an integer and optional unit (example: 10M is 10*1024*1024). Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB, ...
(powers of 1000).
CHUNKS may be: N split into N files based on size of input K/N output Kth of N to stdout l/N split into N files without
splitting lines l/K/N output Kth of N to stdout without splitting lines r/N like 'l' but use round robin distribution r/K/N like-
wise but only output Kth of N to stdout
