bat.sh is a bash script to display the available battery charge.

When I'm running X, I usually monitor battery charge with conky, but I wanted a script to allow quick status checks from the command line. You can dig into /sys/class/power_supply/ if you like, but the [acpi client][] (sys-power/acpi) provides a nicer interface:

$ acpi -b
Battery 0: Discharging, 99%, 05:06:14 remaining
