    Creating a shell script to prompt for a username and password is common for authentication or user creation tasks in Linux. Below is a secure and functional approach.

    Steps to Implement

    1. Prompt for Username and Password Use read for username and read -s (silent mode) for password to hide input.

    #!/bin/bash

    # Prompt for username
    read -p "Enter Username: " username

    # Prompt for password securely
    read -sp "Enter Password: " password
    echo

    # Simple authentication check
    if [[ "$username" == "admin" && "$password" == "admin123" ]]; then
    echo "Login successful. Welcome, $username!"
    else
    echo "Login failed. Invalid credentials."
    fi
    Gekopieerd.

    This method is useful for login validation without storing passwords in plain text.

    Secure User Creation with Encrypted Password

    If you want to create a new system user with the entered credentials:

    #!/bin/bash

    # Check if running as root
    if [[ $EUID -ne 0 ]]; then
    echo "Only root can add users."
    exit 1
    fi

    read -p "Enter new username: " username
    read -sp "Enter password: " password
    echo

    # Check if user exists
    if id "$username" &>/dev/null; then
    echo "User '$username' already exists."
    exit 1
    fi

    # Create user with encrypted password using OpenSSL SHA-512
    useradd -m "$username" -p "$(openssl passwd -6 "$password")"

    if [[ $? -eq 0 ]]; then
    echo "User '$username' created successfully."
    else
    echo "Failed to create user."
    fi
    Gekopieerd.
    What is a bash script?
    The Bash script presented here automates the process of user creation on a Linux system. By prompting the administrator for a username and password, it checks for empty inputs and pre-existing users, then securely creates a new user account. Let me first show what the output of the script looks like:
