I needed a quick way to determine my IP address for a script. If you run the ip addr show command it outputs a lot of information I don’t need. I settled on using grep, awk, and cut to get the information I want

ip addr show <interface name> |egrep 'inet '| awk '{print $2}'| cut -d '/' -f1

The result is a clean IP address. Beautiful. Thanks to this site for insight into how to use cut.
