Trouble with bash shell and macchanger

[anova]

Hello,
I am trying to write my own script that will pass user input to the macchanger program(I tire of typing ifconfig <interface> up and down over and over).

So I want to call a script that will close and open the interface for me, but accept user input for a specific mac address and pass it through to the macchanger program.
This is what I have attempted so far.

#1

#!/bin/bash
ifconfig wlan0 down
read -p "Enter Mac Address: " MACaddress
macchanger -m $MACaddress
ifconfig wlan0 up

#2

#!/bin/bash
ifconfig wlan0 down
echo "Enter Mac Address:
read MACaddress
macchanger -m $MACaddress
ifconfig wlan0 up

#3

#!/bin/bash
ifconfig wlan0 down
echo "Enter Mac Address:
read MACaddress
macchanger --mac=$MACaddress
ifconfig wlan0 up

I get this as a response for everything.

GNU MAC Changer
Usage: macchanger [options] device

Try `macchanger --help' for more options.

So there is obviously something I am missing. Either if the shell is just plain wrong, or maybe it has to due with the type of data that is being passed?

Could someone point me to a good resource that will help me figure this out?

Thank-you

hi
i'm not expert :

#!/bin/bash
ifconfig wlan0 down
echo -n "Enter mac-address ? "
read mac
macchanger -m $mac wlan0
sleep 2
clear
echo -e "REMEMBER..your new mac-address is $mac"
ifconfig wlan0 up
ifconfig wlan0

play with it a bit and change it to your liking
bye

With zimmaro's permission, brother, the sintaxis to macchanger is : macchanger "options" "your iface"..I think you are missing the iface to which you want to assign the new mac to.
Options: --mac ---- xx:xx:xx:xx:xx:xx
--show ---- Print the current mac.
--ending ---- Don't change the vendor bytes.

Please refer to "man macchanger".

Any way, zimmaro posted it the way it should be...

Something else, after changing mac address, I would place a 2 sec sleep, just like zimmaro propose it. It takes a little bit of time when changing mac...

Good work Anova.

Zimmaro, excellent as always.

Luck.

Well - I now feel like an idiot. I got so caught up with assuming I was using the wrong commands that I didn't even see that I forgot to implement an interface.

Lesson Learned.


Thank you - works perfectly.
