Awk to Sum Columns - Dev How To

Simple sum¶

Consider this .csv file:

sample.csv

ID,AMOUNT
1,3.33
2,8.66

We can then use this Awk program to sum the amount column:

$ awk -F ',' '{ sum+=$2; } END { print sum; }'

And then feeding the file to the program:

$ awk -F ',' '{ sum+=$2; } END { print sum; }' ./sample.csv
