Script to display Mac battery information

· apple, hardware, software

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):

The promise of travel has always been transformation: we go away and return changed, more broad-minded, more enlightened about the world. In ‘The Case Against Travel’ (non-paywalled archive view here) Agnes Callard argues that not only does travelling rarely change us, we’re the ones changing the places we visit:

“Touristic travel exists for the sake of change. But what, exactly, gets changed? Here is a telling observation from the concluding chapter of [Hosts and Guests, the classic academic volume on the anthropology of tourism]: ‘Tourists are less likely to borrow from their hosts than their hosts are from them, thus precipitating a chain of change in the host community.’ We go to experience a change, but end up inflicting change on others. ...
