bash script to email updated ip


Hi all. There is my problem. Everyone once in a great while I will need to restart my Redhat server. For now I have been relying on a dynamic DNS issued by my school: helios.resnet.nmu.edu (server address). Because the admins here are retards, they sometimes drops my hostname from the DNS.
I have tried using dynamic dns accounts at various free places, but I cannot for the life of me get the clients to work.

Anyways, I was talking with a friend who said writing a bash script to email me anytime the IP changes (that includes when I restart it).
Cool... but I have 0 experience with bash scripting. I know this would be a good place to start, but its still a little over my head.

So I was wondering if anyone out there had sometime smiliar, or the same as this, and wouldnt mind sharing it.
Thanks for your time.

Eric

If anyone would like to do the same, here is what I used. It works great:

ifconfig | head | grep "inet addr" | mail -s newip emailaddress
