Support two easy programming solution

Durs

Hallo everybody,

I am just an hobby VPS'ler. I am running some rented Servers here. For automatation reason I try to find a solution for me.
Please help me out.

First is I want automate update script the firewall ufw. For this reason I am stuck with the port of wireguard.

I want combine two linux command. I dont know how

command wg show | grep port
output is
listening port: 50 #the port is different in every of my VPS.

hope the get the command
ufw allow 50

Second is extend very common github wireguard script

After first configuration i want create 10 user with one command or one bash script.

I have try
wget https://git.io/wireguard -O wireguard-install.sh && bash wireguard-install.sh -1 -13 -3
but it is not really working.

Please excuse my easy question, but as mechanical engineer. I am not quite skilled in the IT. Google or other Investigation I could not find a solution.

Maybe this ? This will tell awk to find line with port in it, then print last field.

ufw allow $(wg show | awk '/port/{ print $NF }')

This assume port always located in last field, I don't use wireguard so I don't know.
