Find IPs, on OS X and Linux

ips.bash

function ips {
  /sbin/ifconfig | tr '\t' ' ' |              # OS X gives us tabs, remove them 
  sed -n '/^ *inet / { s/// ; p ;}' |                       # Only IPv4, thanks
  cut -d' ' -f1 |                          # Throw away everything but the addr
  sed s/addr:// |                                 # Strip addr: prefix on Linux
  fgrep -v 127.0.0.1                           # We already know about this one
