[ale] scripting challenge du'jour

[J. D.]

I'm sure there are much better ways but here is my stab at it.

#!/bin/bash
# script to parse the output of ifconfig

IFACE1=eth0
IFACE2=eth1

echo "$(/sbin/ifconfig $IFACE1 |grep inet |grep -v inet6 |cut -d":" -f2 |cut
-d" " -f1)"      "$(/sbin/ifconfig $IFACE1 |grep inet |grep -v inet6 |cut
-d":" -f4 |cut -d" " -f1)"

echo "$(/sbin/ifconfig $IFACE2 |grep inet |grep -v inet6 |cut -d":" -f2 |cut
-d" " -f1)"      "$(/sbin/ifconfig $IFACE2 |grep inet |grep -v inet6 |cut
-d":" -f4 |cut -d" " -f1)"
