Battery
Battery is a little bash script that uses Spark to display the battery status on your tmux sessions or the terminal.
Features
- 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).
Requirements
Right now, battery requires Spark to graph your battery status. Battery can run on both Mac OS X and Linux.
If you don't want to use Spark, you can use the -a
flag, for ascii output:
Install - Mac
Homebrew
Just do (case sensitive)
brew tap Goles/battery
brew install battery
One Liner
(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,
like /usr/local/bin
# 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
NOTE: This 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.
Usage
Terminal
-
Run Battery (From the terminal)
battery
You should see something like this:
tmux
-
Be sure to make tmux display utf-8 characters by running it with the
-u
flagtmux -u
-
Add the following line to your
~/.tmux.conf
fileset -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:
Flags
The flag -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 upower
.
Battery displays an emoji by default. You can disable this behaviour by passing the -e
flag.
The flag -z
will add zsh escape characters to the output of the script.
