Xmonad/Config archive/Josh Rickmar's dzenscript

This script handles the right side of my statusbar. It shows my system using uname, my currently playing song from XMMS2, remaining battery life, and the date and time.

#!/bin/sh

UPDATE=1
SYSTEM=`uname -sr`

while :; do
    DATE=`date +"%a %B %d, %I:%M %p"`
    BATTERY=`sysctl -n hw.acpi.battery.life`
    # if xmms2d is running
    if pgrep xmms2d > /dev/null ; then
        # another if statement, stopped or not
        if [ `nyxmms2 status -f "\\${playback_status}"` = "Stopped" ]; then
            XMMS2=" ^fg(green)XMMS2 is stopped^fg() |"
