Bash Scripting with Conky -- How to implement?

Question

Hey Folks, my first post here and I'm looking for a bit of help. I've created a bash script to work with conky in which its purpose is to change the color of the battery bar depending on current voltage.
Here's the bash script:
#!/bin/bash
# Change Conky battery color depending on charge
chrg=`cat /proc/acpi/battery/BAT1/state | grep "remaining capacity" |
awk '{print $3 }'`
echo $chrg
if [ $chrg -lt "3499" ]; then
${color red}${battery_percent BAT1}% ${battery_bar 4 BAT1}
elif [ "$chrg" -lt "5100"]; then
${color orange}${battery_percent BAT1}% ${battery_bar 4 BAT1}
else ${color green}${battery_percent BAT1}% ${battery_bar 4 BAT1}
fi
Essentially what it is supposed to do is grab and store the "remaining capacity" and if its lower than a certain point it changes color. What I'm having trouble with is actually implementing the colors into conky. Right now all it is doing is printing the charge as you can see. Any help would be appreciated. Thanks!

I had this issue, took me three days to solve. Using if_match, put all your if_matches in a line, with each option having its color of choice, then put the bar, or % at the end.  You will need to make sure it is in sequential order so the color will not overlap the color you want for the state in the if_match. I know this is an old thread, I will edit my post when I get on my netbook with the code.
I found this thread on a google search for bash and conky usages.
[edit] here was my solution for the if_match using the battery.
${if_match ${battery_percent BAT1} <= 49}${color0}${endif}${if_match ${battery_percent BAT1} <= 20}${color9}${endif}${if_match ${battery_percent BAT1} >= 50}${color4}${endif}${battery BAT1} ${alignr}${battery_bar 6,160 BAT1}
I have my colors set yellow for 49% and below, red 20% and lower, and last green for 50% and higher. Essentially this will pick yellow for under 49% and the if_match for red under 20%, the red will override the yellow, this is why order is important.
Remember this is all in one line, now there are cleaner ways of setting this up using lua. That is something I am still working on.
