Please help with interactive script

moosedaddy · 12-08-2005, 01:59 PM

I have a laptop and when I boot I disable both the built in wireless and the on board lan. I need a script that will ask if I want wireless started (dhclient wlan0) if so load ndiswrapper and have an option to enter the encryption key or start the lan (dhclient eth0).

I would like something similar to what I have below.

#!/bin/bash

echo "Start wireless?"
read WIRELESS
if $WIRELESS = N; then dhclient eth0
if $WIRELESS = Y; then modprobe ndiswrapper
echo "Enable Encryption?"
read KEY
if $KEY = N; then dhclient wlan0
if $KEY = Y; then iwconfig wlan0 key xxxxxxxxx
dhclient wlan0

Any and all help would be appreciated!

moosedaddy,

I just hacked this up together so I'm not sure if it will work or not. Hopefully it will get you on your way though.

Code:

#!/bin/bash
echo -n "Start wireless? (Y/N)"
read wireless
if [ "$wireless" = "N" ]; then
        dhclient eth0
elif [ "$wireless" = "Y" ]; then
        modprobe ndiswrapper
fi
echo -n "Enable Encryption? (Y/N)"
read key
if [ "$key" = "N" ]; then
        dhclient wlan0
elif [ "$key" = "Y" ]; then
        iwconfig wlan0 key xxxxxxxxx && dhclient wlan0
fi

Good luck,
Kristijan

Thanks that worked just as I wanted.

moosedaddy,

Your welcome!

However, the script is case sensitive. So if you enter 'y' instead of 'Y', it won't work. It's not to hard to fix it, but I'm at work at the moment.

Let me know if you want it adjusted, or better yet, google for some bash scripting tutorials and have a go at it yourself.

Cheers,
Kristijan
