getip.sh suggestion

I use my raspi on wifi quite a lot but advmenu then doesn't show the IP address. I've edited the getip.sh file to allow for wifi and ethernet connections. Thought I would share it:

#!/bin/bash

eIP=$(/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}')
wIP=$(/sbin/ifconfig wlan0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}')
blank=""

if [ "$eIP" != "$blank" ]; then
echo "eth0 available"
IP="SeIP"
elif [ "$wIP" != "$blank" ]; then
echo "eth0 unavailable"
echo "wlan0 available"
IP="$wIP"
else
echo "eth0 unavailable"
echo "wlan0 unavailable"
IP="$blank"
fi

You may need to adjust the locations of the files. Please let me know whether it works.

Thanks! If you have a GitHub account you can put that into the http://github.com/ssilverm/PiMAME repo yourself. If not, I'll do it later today.

Thanks for addition!

I would make these two subtle changes to prevent error messages on the screen:

eIP=$(/sbin/ifconfig eth0 |& grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}')
wIP=$(/sbin/ifconfig wlan0 |& grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}')

The additional "&" after the first pipe sends errors to the grep instead of standard out. This will prevent messages about interfaces not being enabled.

Howdy, Stranger!
