1) if you insist on this approach, here's a hint:
  curl -o - http://getip.com/ 2>/dev/null|grep 128
Replace 128 with some part of your IP number that you're confident
will not change. In the example, I used the left 3 digits of my IP
number. Use sed or awk to scrape off the crud that wget will spew out
along with the IP number.

2) why not just use /sbin/ifconfig -a? Your machine knows its own IP
number as well or better than getip.com.

3) why not man curl? That is, read the man page of the command you are
asking about. You don't sound like you've even tried to do your
homework.
