A simple program that accepts values indefinetly from the user, and then automatically averages them: best used in situations where you can't pull stats with an API or use raw text data.
If you have not built C programs on linux, you may have to install the C build essentials first:
sudo apt-get install build-essential
Clone and run the makefile (just copy and paste these commands):
git clone https://github.com/LEDparty/get-average
cd get-average
make
sudo install average /urs/local/bin
Just run the program with no arguments, and it will keep asking you to enter values until you enter "ok" or some other non-floating point or integer input:
average
