BASH Arrays and randomization

I have a function with nested loops that takes IP, port, packetsize and source port and needs to shuffle it.

I've tried to get the below code to work.

nmapcommandscreator(){
printf "53\n80\n443\n67\n20" > randomport
shuf -i 50-100  > pcktsize
if [[ -f ./targets1 && -f ./ports ]];then
readarray -t dstarray < ports
readarray -t srcarray < randomport
readarray -t pcktsizearry < pcktsize
RANDOM=$$$(date +%s)

srcports=${srcarray[$RANDOM % ${#srcarray[@]}]}
rndmdatalgnth=${pcktsizearry[$RANDOM % ${#pcktsizearry[@]}]}

for ip in $(cat targets1 ) ;
    do for port in "${dstarray[@]}";
        do for sourceip in "${srcarray[@]}";
            do for pcktsize in "${pcktsizearry[@]}";
                do printf "nmap $ip -p $port -Pn --source-port $srcports  --data-length $rndmdatalgnth -oA nmap_result_$ip-$port\n"; done ;done;done;done > nmapCommands-EvasionSorted_4 && sort -R nmapCommands-EvasionSorted_4| shuf > nmapCommands-Evasion_4-ready && rm nmapCommands-EvasionSorted_4

else
    echo "targets or ports missing"
fi
}

What i expected to get is lines as followed.

instead, what im getting is this:

what im obviously doing to do here, is to read arrays of destination port, source port, and packet size, from files using the "readarray" in bash4, and print the destination port for each IP, and only use a random value from the packetsize and source port arryes in each line.

Could someone please enlighten me as to how i would do that.

Thanks ! Roy
