Trying to do a nmap scan on a list of ip's. It won't go through the list with $-CodePudding

Please help I'm very new to this. Any help or references where i can get help are greatly appreciated. Shouldn't the $ be replaced with the ip's in the iplist?

for ip in $(cat iplist.txt); do sudo nmap -sS -p 80 -T4 $ip & done

Not sure what your & is doing there. You might want to replace it with ;. So it reads - for ip in $(cat iplist.txt); do sudo nmap -sS -p 80 -T4 $ip; done
