Getting The Source Path

Let's start building the backup script! The first step is to create a script that asks the user for the source directory they want to back up.

Create a shell script called backup.sh that:

1. Starts with the shebang line (#!/bin/bash)
2. Uses read -p to prompt the user with: Enter source directory:
3. Stores the user's input in a variable called source_dir
4. Prints the message: Backing up: [source_dir]

Make the script executable. Then run it and enter documents when prompted.

Your final output should be:

Backing up: documents

Hint: Use read -p "Enter source directory: " source_dir to display the prompt and capture input in one line. Remember to use chmod +x to make the script executable before running it with ./backup.sh.
