Battery is a little bash script that uses Spark to display the battery status on your tmux sessions or the terminal.
- Changes color to reflect battery status (Green, Yellow, Red)
- Displays battery percentage
- Graph bar changes its values between 0 and 100% (thanks to spark)
- If you don't like the default colors, you can specify the good, medium and warning battery status colors using flags (read usage).
Right now, battery requires Spark to graph your battery status. Battery can run on both Mac OS X and Linux.
Install - Mac
Just do (case sensitive)
brew tap Goles/battery brew install battery
(Cut & Paste on terminal to install on
/usr/bin, btw, try to run from
~/ or other writable dir)
brew install spark; curl -O https://raw.github.com/Goles/Battery/master/battery ; \ sudo mv battery /usr/bin; sudo chmod 755 /usr/bin/battery
Step by Step
Install spark (with Homebrew on Mac OS X)
brew install spark
Copy battery somewhere in your path & fix permissions
sudo cp battery /usr/bin
sudo chmod 755 /usr/bin/battery
Install - Linux
Linux support is still being tested. It ought to work properly in Debian and
Ubuntu, but is largely untested in other distributions. Using linux requires
upower, which should be included, or available, on most linux distributions.
It's recommended to install this somewhere in your path that is writable,
# if you also want to use spark curl -O https://raw.githubusercontent.com/holman/spark/master/spark mv spark /usr/local/bin chmod u+x /usr/local/bin/spark curl -O https://raw.githubusercontent.com/goles/battery/master/battery mv battery /usr/local/bin chmod u+x /usr/local/bin/battery
spark is not the same
spark that you would install by doing
$ sudo aptitude install spark
That is Apache Spark, which is a general engine for large-scale data processing.
Run Battery (From the terminal)
You should see something like this:
Be sure to make tmux display utf-8 characters by running it with the
Add the following line to your
set -g status-right "#(/usr/bin/battery -t)"
reload the tmux config by running
tmux source-file ~/.tmux.conf.
You should now see something like this at the bottom right corner:
-b will set a different battery path, the default value is
/sys/class/power_supply/BAT0. You can specifiy the colors for good battery level, middle battery level, and warning battery level with the flags
-g -m -w.
Note: You should use color names for when in tmux mode and ascii colors in terminal mode.
In Mac OS, you can specify to use pmset with the
-p flag; without it, the program uses
ioreg. In Linux, this flag is ignored, and always uses
Battery displays an emoji by default. You can disable this behaviour by passing the
-z will add zsh escape characters to the output of the script.
