Find the primary IP of local machine

Get the IP of all interfaces:

ifconfig | grep -Eo 'inet (addr:)?([0-9]*\.){3}[0-9]*' | grep -Eo '([0-9]*\.){3}[0-9]*' | grep -v ''

Get the IP of a specific interface:

For eg (wlo1)

ifconfig wlo1 | grep -Eo 'inet (addr:)?([0-9]*\.){3}[0-9]*' | grep -Eo '([0-9]*\.){3}[0-9]*' | grep -v ''
