Create script to add user and create directory

first off let me introduce myself. My name is Eric and I am new to linux, I am taking an advanced linux administration class and we are tasked with creating a script to add new users that anyone can run, has to check for the existence of a directory. if the directory does not exist then it has to be created. if it doe then it has to just proceed with the new user addition.

1. The problem statement, all variables and given/known data:

how do i get this script to be able to create the directory if it does not exist?
or how do i get this script to run as root?
thanks in advance

2. Relevant commands, code, scripts, algorithms:
i have the script partially written i have rudimentary if/then/else statement where the first line reads:

Code:

echo "What department are you assigned to?"
read department     # $department
sleep 2
echo "you are assigned to the: $department"
sleep 7
clear

if [ -d /home/timberwolves/$department ]
then 
         echo "directory exists"
         sleep 3
         echo "what is your first name"
         read FirstName    # $FirstName
         sleep 2
         clear
         echo "what is your last name?"
         read LastName     # $LastName
         echo "You entered: $LastName"
         sleep 2
         clear
         echo "Please type your password (must be at least  characters)"
         read password      # $password
         sleep 2
         clear
         echo "The password you chose is: $password"
         sleep 7
         clear
         echo "Your login name will be: $FirstName"
         sleep 2
         clear
         echo "Your home directory will be: /home/timberwolves/$department/$FirstName
          sleep 7
          clear
else
mkdir -p /home/timberwolves/$department
         echo "what is your first name"
         read FirstName    # $FirstName
         sleep 2
         clear
         echo "what is your last name?"
         read LastName     # $LastName
         echo "You entered: $LastName"
         sleep 2
         clear
         echo "Please type your password (must be at least  characters)"
         read password      # $password
         sleep 2
         clear
         echo "The password you chose is: $password"
         sleep 7
         clear
         echo "Your login name will be: $FirstName"
         sleep 2
         clear
         echo "Your home directory will be: /home/timberwolves/$department/$FirstName
          sleep 7
          clear
fi

0store-secure-add

0STORE-SECURE-ADD(1)													      0STORE-SECURE-ADD(1)

NAME

       0store-secure-add -- add an implementation to the system cache

SYNOPSIS

       0store-secure-add DIGEST

DESCRIPTION

       This  command  imports  the  current  directory	into  the  system-wide	shared	Zero Install cache, as /var/cache/0install.net/implementa-
       tions/DIGEST.  This allows a program downloaded by one user to be shared with other users.

       The current directory must contain a file called '.manifest' listing all the files to be added (in the format required by DIGEST), and this
       file  must have the given digest. If not, the import is refused. Therefore, it is only possible to add a directory to the cache if its name
       matches its contents.

       It is intended that it be safe to grant untrusted users permission to call this command with elevated  privileges.  To  set  this  up,  see
       below.

SETTING UP SHARING

       To enable sharing, the system administrator should follow these steps:

       Create a new system user to own the cache:

       adduser --system zeroinst

       Create the shared directory, owned by this new user:

       mkdir /var/cache/0install.net

       chown zeroinst /var/cache/0install.net

       Use visudo(8) to add these lines to /etc/sudoers:

       Defaults>zeroinst env_reset,always_set_home

       ALL ALL=(zeroinst) NOPASSWD: /usr/bin/0store-secure-add

       Create a script called 0store-secure-add-helper in PATH to call it. This script must be executable and contain these two lines:

       #!/bin/sh

       exec sudo -S -u zeroinst /usr/bin/0store-secure-add "$@" < /dev/null

       The other Zero Install programs will call this helper script automatically.

FILES

BUGS

       This program is EXPERIMENTAL. It has not been audited. Do not use it yet in security-critial environments.

       The env_reset line in sudoers may not be required. sudo(1) seems to do it automatically.

       If  sudo  let us check whether we could call a command then we could switch to using it automatically, instead of needing to add the helper
       script. Currently, sudo delays for one second and writes to auth.log if we try to use this system when it hasn't been set up.
