I'm voting to close this question as off-topic because "*write a script that does X for me*" is not a question. Hire a programmer. — melpomene, May 05 '17 at 07:28

I would vote to reopen, but the question still needs to state clearly what the actual problem with the existing attempt is. — chepner, May 05 '17 at 12:03

 nmap -sn $1"/"$2 | awk '/report for/ { print $5 }' > ipadds

This will give you an easy list of all the active hosts on the network using a given ip address and sbnet prefix.
