echo `~corcoraj/bin/ifconfig -a|grep addr:| sed "/^inet addr:/,/^B/"`:0
So for a given output

eth0      Link encap:Ethernet  HWaddr 00:50:04:54:22:69
          inet addr:158.234.99.62  Bcast:158.234.99.255  Mask:255.255.252.0
          UP BROADCAST RUNNING  MTU:1500  Metric:1
          RX packets:1131214 errors:0 dropped:0 overruns:8 frame:0
          TX packets:42005 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          Interrupt:10 Base address:0x1080

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:3924  Metric:1
          RX packets:46 errors:0 dropped:0 overruns:0 frame:0
          TX packets:46 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0

I firstly grep the highlighted line. And I have removed the inetaddr: bit, But
how do I parse the remainder.

Thanks.

Jason.
