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.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
