1. Given the list of grades, `grades.txt`, for the input file below, create an `awk` script, `quiz.awk`, which prints only the student’s name (first then last), grade, and assignment for the section passed as an argument. At the end, print the average grade and the number of failing grades (<= 60) for the specified section. Each line in the input file contains the following fields in this order: *lastName, firstName, section, assignment, grade*. Assume names do not have spaces. Print the output to a file called `gradesFiltered.txt`.
|
||
```sample

||
Adams John 2 1 30
