That works perfect until I try to output it from my array. (Which I dearly need).

Code:
#!/bin/bash

if [ 5.21 = $(nmap --version | awk '/Nmap/ { print $3 }') ]; then
    i=5  t=report    # field index and target text
else
    i=2  t=Host
fi

/sbin/ifconfig | awk '/inet addr/ && !/127.0.0.1/ && !a[$2]++ {print substr($2,6)}' |
    while read ip; do
          first+=( "$(nmap -sP ${ip%.*}.0/24 | awk 'index($0,t) { print $i }' t="$t" i="$i" )" )
          sleep 1
    done

echo "${first[@]}"

The above outputs absolutely nothing. Don't bother running it.
