battery_charge is a simple cross-platform command line utility (python3) for checking battery status.

All the script does is to show the current battery percentage and whether it is charging.

• Python 3
• Linux: upower UPower command line tool (comes with the system for Ubuntu)
• OS X: ioreg (comes with the system)
• Windows: wmi python module
  • install with pip install wmi using the pip from python 3

• ./setup.py install (run with sudo on Linux)

• Windows 10
• OS X 10.10.5 (Yosemite)
• Ubuntu 14.04 (Trusty Tahr)

You will need to put "X:/Python3X/Scripts" into your PATH on Windows.

$ battery_charge
99 ac_power

Use read command to get both the battery percentage and the status into variables.

$ bat_info=`battery_charge | tr -d '\r\n'`
$ read bat_percentage bat_status <<< $bat_info
$ echo $bat_percentage
95
$ echo $bat_status
discharging

You could create a battery segment on $PS1 using this script with Oh-my-zsh + agnoster theme.

Here are some demos. See demo/zsh_prompt for more detail.
