And,
ifconfig eth0 | grep inet | awk '{print $2}' | awk -F : '{print $2}'
The bash var substitution (Johnson) is promising; I'll have to try that. (The
exact one provided fails on ipv6 enabled ifconfig--notably all of Ubuntu--but
once working, looks neater than the sed greps awk and does curls. (Though,
OpenBSD might not like it as much as the sed greps awk deal.)
