add local user

add-local-user.sh

#! /bin/bash

# this script will create new user accounts 

# enforce execution with a root priviledges, 
# return status 1 if not root

if [[ "${UID}" -eq 0 ]]
then
        # enter the username (login), 
        read -p 'Enter the username to create: ' USER_NAME

        # the name for the person who will be using account 
        read -p 'Enter the real name: ' COMMENT

        # get initial password
        read -p 'Enter the password to use for the account: ' PASSWORD

        # create a new user with a input provided by the user
        useradd -c "${COMMENT}" -m ${USER_NAME}

        # Check to see if the useradd command succeeded
        if [[ "${?}" -ne 0 ]]
        then
                echo 'The account was not created'
                exit 1
        fi

        # Set the password for the user
        echo ${PASSWORD} | passwd --stdin ${USER_NAME}

        # Check to see if the passwd command succeeded
        if [[ "${?}" -ne 0 ]]
        then
                echo 'The account was not created'
                exit 1
        fi

        # Force password change on first login
        passwd -e ${USER_NAME}

        # display the user name, password, the host where the account was created
        echo "User name: $USER_NAME"
        echo "Password: $PASSWORD"
        HOSTNAME=$(uname -n)
        echo "Host: $HOSTNAME"  
else
        echo "The sript requires root priviledges" 
        exit 1
fi

great!
would be better however to do like

#!/bin/bash
if [[ $EUID -ne 0 ]]; then
   echo "The script requires root priviledges" 
   exit 1
fi

... then the rest of code
