alias battery='echo "Battery %=" ; cat /sys/devices/platform/olpc-battery.0/power_supply/olpc-battery/capacity ; echo "Battery Status: " ; cat /sys/devices/platform/olpc-battery.0/power_supply/olpc-battery/status'

Adding this to your ~/.bashrc will give you quick access to your current battery % as well as whether or not it's being charged. Easy peasy...

Do you mind giving instructions on how we add this to your ~/.bashrc -- where is that file and how do I add text to it?

cd ~
vi .bashrc
<Ctrl+g key>
o
alias battery='echo "Battery %=" ; cat /sys/devices/platform/olpc-battery.0/power_supply/olpc-battery/capacity ; echo "Battery Status: " ; cat /sys/devices/platform/olpc-battery.0/power_supply/olpc-battery/status'
<Escape key>
:x

That adds an alias called battery. After you do the above, typing the command battery at the bash prompt will show you the status.
