I just needed to store the LAN IP (for ipv4) in a variable for a specific task in a bash script. I figured I'd share. I sent it to a variable with VAR=$(stuff) and used it later on. I put the exit 0 in the if statement to make it so that it breaks if there are more than one IPv4 addresses assigned. I only wanted the first one. Edit: Bear in mind, my network mask is a double digit number so if you have a smaller nw mask you'd need to edit the sed statement. Show Sample Output
0ip addr show | grep "inet " | while read INET IP TRASH; do if [ $IP != "127.0.0.1/8" ]; then echo $IP; exit 0; fi; done | sed s:/[1-9][1-9]:"": -
