in thread How could I create a command line quiz?

Yes, you're right. I want to get the structure of the script correct first and then I'll replace the backticks with perl code

I've built up to this part slowly by testing a basic subroutine that outputs static values, then added more functionality as my knowledge builds.

    the structure of the script
    Hmm. You seem to do
    1. read the list of questions in
    2. print the first question
    3. read the list of answers
    4. print the first answer
    Now, how would you go for a random question, considering that there can be multiple answers for a question?
    1. read the list of questions in - ok
    2. print a random question - ok
    3. read the list of answers - ok
    4. print … which answer???
    Better control flow would be:
    1. read the list of questionss and answers, preserving the relation between q and a
    2. select a random q&a group
    3. print the selected question
    4. print the corresponding answers
    Problem: you need a structure, yes, but not only of the script (control flow) but also for your data (be that arrays or objects). That might be possible with bash and grep, but that will be very specific and therefore difficult to translate to any other language, including Perl
