Bash Scripting: Building Five Programs

Learning Documentation

This repository contains five small Bash programs created as part of the freeCodeCamp's Relational Database Certification. Each program serves a different purpose and demonstrates various Bash scripting techniques.

Programs

1. Questionnaire (questionnaire.sh): A simple questionnaire script that prompts the user with three questions and prints the responses.

2. Countdown Timer (countdown.sh): A countdown timer script that takes a positive integer as an argument and counts down to zero, pausing for one second between each number.

3. Bingo Number Generator (bingo.sh): A script that generates a random bingo number between 1 and 75 and prints it along with the corresponding letter (B, I, N, G, or O).

4. Fortune Teller (fortune.sh): A fortune-telling script that prompts the user to ask a yes or no question and provides a random response from a predefined set of answers.

5. Five Program Runner (five.sh): A script that runs all the other four programs consecutively.
