This script and example were prepared to show how to use the awk program to split the BlackBoard download to multiple files. This assumes that you selected format of results = By Question and By User, such that each row represents a single question for a single student. See the csv file as an example.

Downloading from BlackBoard (separate row per question)

Go to Grade Center > Full Grade Center > Navigate to the Assignment or test's Column > Click on the down arrow next to the column's title > Select Download Results. Select 'By Question and User'. This gives you a file named Test.downloading.csv

Splitting into individual files

To run the awk program file you can try the following command.

# This program sorts input by a specified column
# Author: Katherine Chuang (@katychuang on Github)
# example awk -v column=2 -f prog.awk data.csv
# 
# Program Steps:
# 1. Read input and store items in an array of array. 
# 2. Sort by column specified (user input letter c)
# 3. Print the sorted version
