Dynamic menu selection? Help..

Hi guys, i would like to create a program that allow user to show the information of certain thing such as network card.

I would like the menu to be dynamic, for example:
my computer system have 2 network card inserted at the moment, therefore the menu will have 2 choice for the user.

eth0
lo

However, if there's changes made, for example another network card was added which name lo1. The program will update the changes and allow user to have the latest choice.

eth0
lo
lo1

I am up to here at the moment. guide me guys..
Code:
#!/bin/bash
clear

ifconfig -a | sed -n 's/^\([^ ]\+\).*/\1/p' > somefile

array=($(<somefile))

whiptail --title Networking --menu "select your choice" 16 78 5 "${array[@]}"

Regards,

Malfolozy

NAME
tk_popup - Post a popup menu SYNOPSIS
tk_popup menu x y ?entry? _________________________________________________________________ DESCRIPTION
This procedure posts a menu at a given position on the screen and configures Tk so that the menu and its cascaded children can be traversed with the mouse or the keyboard. Menu is the name of a menu widget and x and y are the root coordinates at which to display the menu. If entry is omitted or an empty string, the menu's upper left corner is positioned at the given point. Otherwise entry gives the index of an entry in menu and the menu will be positioned so that the entry is positioned over the given point. EXAMPLE
How to attach a simple popup menu to a widget. # Create a menu set m [menu .popupMenu] $m add command -label "Example 1" -command bell $m add command -label "Example 2" -command bell # Create something to attach it to pack [label .l -text "Click me!"] # Arrange for the menu to pop up when the label is clicked bind .l <1> {tk_popup .popupMenu %X %Y} SEE ALSO
