To be fair, and I don't have your context on this, but looking at your link of the assignment for [0] it appears to me that this is more of an exercise in getting people comfortable with more advanced bash features, specifically looks like it relies fairly heavy on regex? I agree that BS4 is a better tool for this job, certainly, but there is perhaps a point in what is going on here too. As far as the second one goes, I bet that has more to do with the professors particular familiarity with C than it does an understanding of what the best tool of the job for that is. I'll cede that point :)
