Hey all,

I've recently discovered Geektool and its spin-off Nerdtool, and I've found a way I wish to implement this:

If my battery charge falls below a certain threshold, I would like script to display an image. However, I have not yet found out how. This is the script I am currently using:

Code:
#! /bin/bash
charge=`/usr/sbin/ioreg -l | /usr/bin/grep -i capacity | /usr/bin/tr '\n' ' | ' | /usr/bin/awk '{printf("%.0f",$10/$5 * 100)}'`

if [ $charge -lt "20" ]; then
echo "20"
fi
This displays a simple "20" if the charge is less than 20%. Now instead, I would like to replace this with an image. I'm new to Mac, so also a relative noob when it comes to bash scripts. Does anyone have a clue how to achieve this? (So I would like to replace the echo "20" part with something that says "hey, lets display image Y found in folder X".)

Any help would be greatly appreciated. Thanks guys.
QUOTE Thanks
