    You can use this:

    #!/bin/bash

if [ ! -f $1 ]; then
  echo "File $1 not found"
  exit 1
fi

number=$(grep total_points $1 | wc -l )
sumTotal=$(grep total_points $1 | awk '{sum+=$2} END { print sum }')
sumToday=$(grep total_points $1 | awk '{sum+=$5} END { print sum }')

echo "Total SUM: $sumTotal"
echo -n "Total AVG: "
echo "scale=5;$sumTotal/$number" | bc

echo "Today SUM: $sumToday"
echo -n "Today AVG: "
echo "scale=5;$sumToday/$number" | bc

    Then save to a file like: script.sh

    Change the permission to executable: chmod +x script.sh

    Then run it: ./script.sh sample.txt

    This will output: 

    Total Record: 3
Total SUM: 429.62
Total AVG: 143.20666
Today SUM: 103.52
Today AVG: 34.50666

    Note:
    $1 will the the input file.

    Here’s more help about the bc command, grep, awk
