Here is one liner that will add the current IP address in the console login screen (if you are not running X as is case for servers): (ip -o -4 a| awk '$2 !="lo" {print "\nIP Address ::"$4}' |tr '\n' ',';echo)>>/etc/issue Just execute the above command as root.

Now I can quick edit this file to create this as shell script as well if required. Continue reading
