Getting IP in a script

[Alan Dayley]

This is good.  I had thought of this, though I would have had to study to
figure out how to pull the address out of the rest.  Now I will have to
study to make sure I understand how this script does it.  ;^)

I was hoping for something more like a function call in perl or grabbing a
system parameter somewhere that simply "gave" me the address.  Is there
nothing "cleaner" than grepping ifconfig output?
