  1. I added this for OSX

    OSX) LOCALIP=`ifconfig | grep ‘inet’| grep -v ‘’ | cut -d: -f2 | awk ‘{ print $2}’`;;

  2. Can be useful on another alerting script in which you are sending the IP of the server is having some problem….
    This is my opinion….

  3. bsr,
    can any1 plzzzzz tell me wat’s the utility of this script (it gives the local address i know!! but y know my local address?!!!!!).

  4. Stefan, why would you give a partial answer? Why not take .1 of a second more and post an example that actually works? It amazes me how stupid smart people can be.

    “Here’s part of an answer to something but I can’t be bothered to actually post a working example. You should see my code comments, they suck.”
