How to scan IP range using nmap?

Scripting language : Bash Shell Script

1. problem statement
I have to create function in which read IP addresses one by one from one file (iplist.txt) and scan these IP using nmap. This scan IP's output is saved in output.txt file and parse output.txt to save only open ports with particular IP in parse.txt file.
format of parse.txt file:

Code:
Code:
ip             port
x.x.x.x        x

2. My goal:
1. Find all ports open on a whole range.
2. Save only open ports with IP address in another file. Don't save filtered or closed ports in this file.

eg. Format of file:
IP_address Open_port
Code:
192.168.0.1         21
192.168.0.1         80
....

so I have write the script which scan IP range. I just want script of second option.
I have attached the script. Please help me if possible to implement second option. In second option, my script take open port/tcp and all other details but i want only ip address with open port.

NAME
mac-vendor - Ethernet vendor file for arp-scan SYNOPSIS
mac-vendor.txt DESCRIPTION
The mac-vendor.txt contains Ethernet MAC to vendor string mappings for arp-scan. It is used in addition to the IEEE OUI and IAB listings in ieee-oui.txt and ieee-iab.txt. It is for MAC-vendor mappings that are not covered by the IEEE manufacturer listings. Each line in the mac-vendor.txt file contains a MAC-vendor mapping in the form: <MAC-Prefix><TAB><Vendor> Where <MAC-Prefix> is the prefix of the MAC address in hex, and <Vendor> is the name of the vendor. The prefix can be of any length from two hex digits (one octet) to twelve hex digits (six octets, the entire Ethernet hardware address). The alphabetic hex characters [A-F] must be entered in upper case. For example: 012345 would match 01:23:45:xx:xx:xx, where xx represents any value; 0123456 would match 01:23:45:6x:xx:xx; and 01234567 would match 01:23:45:67:xx:xx. Blank lines and lines beginning with "#" are ignored. The order of entries in the file is not important. arp-scan will attempt to match larger prefixes before trying to match smaller ones, and will stop at the first match. FILES
