How to find primary ip address on linux machine?

@benny_schoen 

To find the primary IP address on a Linux machine, you can use one of the following commands:

1. Using the "ip" command: ip addr show | grep "inet " | awk '{print $2}' | grep -v 127.0.0.1
2. Using the "ifconfig" command: ifconfig | grep "inet " | awk '{print $2}' | grep -v 127.0.0.1

Both commands will display the primary IP address of your Linux machine, excluding the loopback address (127.0.0.1).
