Or another way that's perhaps a bit more robust under Linux (it
handles secondary IP addresses, scoped sub-routing tables, etc)
DEVICE=eth0
IPADDR=$(/sbin/ip addr show dev $DEVICE scope global primary | \
awk '$1=="inet" {print $2}' | \
cut -d/ -f1)
use "inet6" if you want IPv6 addresses instead.
Also, I find it more readable to use the bash $(xxxx) shell syntax
rather than backticks `xxxxx`. You can do that even for
you ifconfig solution.
