Vending Machine

Inside the Terminal

A vending machine that runs entirely in the terminal. I wrote it in Bash. The script fills the stock with random amounts. You pick a drink, pay with cash, TWINT or PayPal and get the correct change back.

Requirements

We had to write a Bash script that uses functions, loops, user input and conditions. If you typed something wrong, the program had to ask again and keep running.

What I Took Away

• Splitting code into Bash functions
• Checking input and catching wrong entries
• Random numbers for the stock
• Three payment options: cash, TWINT and PayPal
• Error handling in shell scripts
