Average values from stdout over a given interval

npm install -g cli-average

Say you have the following shell script that outputs numbers on stdout

for i in {1..50}; do
  echo $RANDOM;
  sleep 0.3;
done

You can pipe it into avg to generate averages of those values over a given time interval

./random.sh | avg

• avg -t 10s: time interval to average the values over
