change local_ip_v4 variable

[ehrenmann1977]

hi
i have in my server multiple ip addresses, the main one is not the correct ip address that the server has to listen to. I need to create a new variable, that should get the bridge 0 ip, how can i write a command. I tried to do it, but i don't understand { and $ in the variable, sometimes there are two $$. Can somebody help me .

I believe you can set it in default settings as a $$ (global) $ is a single channel variable so per call or something

i tried to read on it but found that it is set internally upon starting, do you know can i set it in vars?
lets say i want to set a new variable called x, but i want to assign it to the ip of my br0,i use this

ip addr show br0 | grep 'inet '

to get the ip, how can i set this variable to run this command.
