Output will look like this:
eth0 Link encap:Ethernet HWaddr 00:0D:B9:13:14:38
inet addr:192.168.24.99 Bcast:192.168.24.0 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Interrupt:10 Base address:0x1000
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:294 errors:0 dropped:0 overruns:0 frame:0
TX packets:294 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:30124 (29.4 Kb) TX bytes:30124 (29.4 Kb)
Note that this machine does not have it's WiFi enabled. This machine's
IP address is 192.168.24.99 (eth0). You could get fancy by using
regular expressions (egrep) but that might seem a bit scary for the
uninitiated.
Hmm, odd that machine appears to have broken counters, oh well I'll
fix that later.
