Script to display Mac battery information

You can see how this script makes that couple very happy.

Quick and dirty script that shows your Mac battery information (health, cycles, etc). If an Apple keyboard or mouse is connected, it’ll also display the battery % of those.

# Battery information
battery() {

	if !ioreg > /dev/null 2>&1; then
		echo "ioreg not found. Exiting."
		return 1
	fi

	_ioreg=`ioreg -l`
	_profile=`system_profiler SPPowerDataType`

	MOUSE=`echo $_ioreg -l | grep -A 10 "Mouse" | grep '"BatteryPercent" =' | sed 's/[^0-9]*//g'`
	TRACKPAD=`echo $_ioreg -l | grep -A 10 "Track" | grep '"BatteryPercent" =' | sed 's/[^0-9]*//g'`
	KEYBOARD=`echo $_ioreg -l | grep -A 10 "Keyboard" | grep '"BatteryPercent" =' | sed 's/[^0-9]*//g'`
	CYCLE=`echo $_profile | grep "Cycle Count" | awk '{print $3}'`

	if [ -n "$MOUSE" ]; then
		echo "Mouse: "$MOUSE"%"
	fi

	if [ -n "$TRACKPAD" ]; then
		echo "Trackpad: "$TRACKPAD"%"
	fi

	if [ -n "$KEYBOARD" ]; then
		echo "Keyboard: "$KEYBOARD"%"
	fi

	if [ -n "$CYCLE" ] && [ "$CYCLE" -ne 0 ]; then
		echo "Mac battery "`echo $_profile | grep "State of Charge" | awk '{print $5}'`"%"
		echo "Charging: "`echo $_profile | grep "Charging" | head -n 1 | awk '{print $2}'`
		echo "Cycles: "$CYCLE
		echo "Condition: "`echo $_profile | grep "Condition" | awk '{print $2}'`
		echo "Health: "`echo $_profile | grep "Maximum Capacity" | awk '{print $3}'`
	fi
}

Outputs something similar to this (no mouse or keyboard connected):

nazgul ~ $ battery
Mac battery 54%
Charging: No
Cycles: 224
Condition: Normal
Health: 89%

This works on zsh and may not work in bash.
