This guide outlines best practices for securing Bash scripts in production environments, ensuring the safety and integrity of your systems and data. 

#!/bin/bash

# Securely executing a command passed as an argument
if [ "$#" -ne 1 ]; then
    echo "Usage: $0 "
    exit 1
fi

# Check for known safe commands
case "$1" in
    ls|pwd|whoami)
        eval "$1"  # Use eval with caution
        ;;
    *)
        echo "Error: Command is not allowed."
        exit 1
        ;;
esac

# Prevent execution in case of a change
trap 'echo "Script exited unexpectedly."; exit 1;' ERR

# Use set to enforce strict mode
set -o nounset   # Treat unset variables as an error
set -o errexit   # Exit immediately if a command exits with a non-zero status

# Main script functionality here
echo "You ran the command: $1"
