ip: get current ip address getip

inet0 is my Net device; adjust to suit. Obviously, I'm generally only interested in this ip, because it's the only one that changes.

This simple script is useful in getting that IP address for other scripts that need to know it e.g. those that update my dynamic DNS.

 

#!/bin/bash

ifconfig eth0

sed -n 's/.*inet addr:\([0-9.]*\).*/\1/p'

 

ping 127.0.0.1 loop

#!/bin/bash
#ping internal loopback address
ping 127.0.0.1

#!/bin/bash

echo "Looking up Mt. San Jacinto College..."
nslookup msjc.edu
