[plug] getting IP address in a shell script

[chris]

something like

ifconfig ppp0 | grep inet | cut -d : -f 2 | cut -d \  -f 1

be careful with spaces, theres 2 spaces towards the end (after the last
\  and before the -f 1 etc) 

this is something I picked up from some dynamic DNS script that I
shamelessly used a lot . 
ppp0 can be any interface eth0 etc - you can stick others in here as
well

something like 

MY_IP = `ifconfig ppp0 | grep inet | cut -d : -f 2 | cut -d \  -f 1`

hope that helps.. )
