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

pbuilder-user-mode-linux(1)					     pbuilder					       pbuilder-user-mode-linux(1)

NAME

       pbuilder-user-mode-linux - personal package builder in UML

SYNOPSIS

       pbuilder-user-mode-linux create [options]

       pbuilder-user-mode-linux update [options]

       pbuilder-user-mode-linux build [options] .dsc-file

       pbuilder-user-mode-linux execute [options] script

       pbuilder-user-mode-linux login [options]

DESCRIPTION

       Front  end  program  to	the  pbuilder suite of programs, used for creating and maintaining user-mode-linux environment and building Debian
       package within the user-mode-linux virtual machine environment.

       Unlike pbuilder , pbuilder-user-mode-linux does not require root privilege to run.  It should be ran under a normal user.

OPTIONS

       create Creates a user-mode-linux root image for the specified distribution using rootstrap software

       update Updates the user-mode-linux root image for the specified distribution.  Also, by specifying the --distribution option, it is  possi-
	      ble to switch the distribution.  Specify a dummy distribution value even for custom apt config files.

       build  Builds the package specified by .dsc-file within the user-mode-linux environment.

       login  Invokes shell within UML.

       dumpconfig
	      dumps configuration information about user-mode-linux, used for debugging.

       execute
	      Invokes a command or script inside UML.  execute will copy the specified file into the UML system, and run it.

	      The remaining command-line arguments are passed on to the script.

       --uml-image [UML image]
	      Specify the UML image to use.

       --eth0 [uml option for eth0]
	      Specify this option as parameter to UML.

	      Specify --eth0=slirp,12345,/usr/bin/slirp-fullbolt to use the slirp connection.

       --uml-ip [IP inside UML]
	      Specify this to set the IP inside UML.

	      This can be set to dhcp for obtaining IP address through DHCP.

       --uml-netmask [netmask]
	      The netmask.

       --uml-network [network]
	      The network address.

       --uml-broadcast [broadcast]
	      The broadcast address.

       --uml-gateway [gateway]
	      The gateway address.

       --mount-tmpfs [yes]
	      Specify whether to mount tmpfs inside UML chroot.

       --uml-hostname [uml-host]
	      The hostname inside uml.

       --distribution [sid]
	      Specify the distribution.  see pbuilder(8)

       --binary-arch
	      Specify only to build binary-arch targets.  see pbuilder(8)

       --timeout timeouttime
	      Timeout build after specified time.  see pbuilder(8)

       --configfile config file to read
	      Makes  pbuilder to read the config file inside UML.  pbuilder-user-mode-linux itself would be affected by the contents of the config
	      file.

       --hookdir location of hooks
	      Makes pbuilder use the specified hookdir inside UML.

       --aptconfdir apt configuretion directory
	      Makes pbuilder to use specified apt configuration directory instead of other settings. See pbuilder(8)

       --override-config
	      Specify this option along with --distribution to switch distribution using pbuilder-user-mode-linux update

       --logfile logfilename
	      Specify this option to make the output go to logfilename as well as standard output.

       --buildresult /dir/to/build/result
	      The directory where build result is placed to

       --uml-debugmode
	      Enable tracing of shell scripts used by pbuilder-user-mode-linux.

       --bindmounts /dir/to/bind-mount
	      Bind-mount the directory inside the chroot inside the user-mode-linux.

       --buildplace place-to-put-COW-file
	      Specify the directory to place the COW file.  The user needs to be able to access that directory, and the directory must exist.

       --uml-login-nocow
	      Do not use COW filesystem when using pbuilder-user-mode-linux login so that changes made in the log in session will persist.

	      Effective in login and exec options.

       --mirror [mirror location]
	      Specifies the URL of Debian mirror to be specified in sources.list inside the chroot.  This option is only valid	when  distribution
	      is being specified, for update and build targets.  The format is something like: http://http.us.debian.org/debian which should point
	      to your favourite mirror.

	      This option can optionally be omitted, and left blank, in which case, this part is skipped.

	      Note that these URLs specified to pbuilder will be used from within the chroot, and specifying file:/somewhere/ will  most  probably
	      fail.

       --othermirror [deb http://xxx/xxx/ ./ | other deb lines... ]
	      The  lines  which is added to the sources.list, delimited with | Like deb http://local/mirror stable main|deb file:/usr/local/mirror
	      ./

	      The deb lines here are the ones that will appear at the top of the sources.list inside the chroot.  Be sure  to  follow  the  syntax
	      rules  of  sources.list(5).   These lines appear at the beginning of the constructed sources file, so this is the place to list your
	      local mirror sites; apt will then use them in preference to the ones listed in --mirror .

	      These options are only valid when --override-config option is specified in update target, or when pbuilder create is being called.

NOTES

       For build and login targets, pbuilder-user-mode-linux will try to use COW devices.

       Inside user-mode-linux, pbuilder-user-mode-linux will mount tmpfs as /tmp to avoid temporary file race  conditions  with  outside  of  UML.
       This may cause problems trying to use files in /tmp directory.

FILES

       /etc/pbuilderrc
	      The system-wide configuration file for pbuilder.

       /usr/share/pbuilder/pbuilderrc
	      The default settings for pbuilder, used as fallback for all values that is not specified in /etc/pbuilderrc.

       /etc/pbuilder/pbuilder-uml.conf
