[plug] getting IP address in a shell script

[Craig Ringer]

Hi all
Any ideas about a non-ugly (ie pref not /sbin/ifconfig eth0 | awk ... ) 
method of getting the local machine's IP address into a variable in a 
shell script? There's probably something obvious I'm missing but apropos 
and google haven't helped on a quick glance.
