Creating a menu within a script file
I am very new to Unix and know the basic commands. I have to write a script file and I'm completely lost. The script file is to show the following at the beginning:

Menu of Options

1. Display all files in a user's home directory.
2. Welcome yourself to the program.
3. Display System Information
4. Exit back to Windows

I have been able to get this to display by use of the echo command. Beyond that, I have no idea what to do. I have search endlessly online for a way to create a menu in Unix and this is all I have to show for it. I also need a line that says "Please enter your choice." Once the user enters a choice, I have no idea how to write the various commands to perform what needs to be done.

Options 3 and 4 seem straightforward if I could get started. However, in option 1 the following criteria have to be met:

1. Display all files in a user's home directory. This should allow the user to look at any user's home directory, provided they enter the correct user name.
2. Put in a safeguard that if the user does not enter a name, that the current user's home directories display.

I have no idea how to work with Option 2.

I'd greatly appreciate it if anyone would please help me with this. Thank you.

sss_useradd

SSS_USERADD(8)							 SSSD Manual pages						    SSS_USERADD(8)

NAME

       sss_useradd - create a new user

SYNOPSIS

       sss_useradd [options] LOGIN

DESCRIPTION

       sss_useradd creates a new user account using the values specified on the command line plus the default values from the system.

OPTIONS

       -u,--uid UID
	   Set the UID of the user to the value of UID. If not given, it is chosen automatically.

       -c,--gecos COMMENT
	   Any text string describing the user. Often used as the field for the user's full name.

       -h,--home HOME_DIR
	   The home directory of the user account. The default is to append the LOGIN name to /home and use that as the home directory. The base
	   that is prepended before LOGIN is tunable with "user_defaults/baseDirectory" setting in sssd.conf.

       -s,--shell SHELL
	   The user's login shell. The default is currently /bin/bash. The default can be changed with "user_defaults/defaultShell" setting in
	   sssd.conf.

       -G,--groups GROUPS
	   A list of existing groups this user is also a member of.

       -m,--create-home
	   Create the user's home directory if it does not exist. The files and directories contained in the skeleton directory (which can be
	   defined with the -k option or in the config file) will be copied to the home directory.

       -M,--no-create-home
	   Do not create the user's home directory. Overrides configuration settings.

       -k,--skel SKELDIR
	   The skeleton directory, which contains files and directories to be copied in the user's home directory, when the home directory is
	   created by sss_useradd.

	   Special files (block devices, character devices, named pipes and unix sockets) will not be copied.

	   This option is only valid if the -m (or --create-home) option is specified, or creation of home directories is set to TRUE in the
	   configuration.

       -Z,--selinux-user SELINUX_USER
	   The SELinux user for the user's login. If not specified, the system default will be used.

       -?,--help
	   Display help message and exit.

THE LOCAL DOMAIN

       In order to function correctly, a domain with "id_provider=local" must be created and the SSSD must be running.

       The administrator might want to use the SSSD local users instead of traditional UNIX users in cases where the group nesting (see
       sss_groupadd(8)) is needed. The local users are also useful for testing and development of the SSSD without having to deploy a full remote
       server. The sss_user* and sss_group* tools use a local LDB storage to store users and groups.
