Simple Menu and coding
I am very new to Unix and don't know much about it. I've been trying to create a menu and what I don't understand is how to execute a command once a user makes a selection. I have the menu set up. In fact, the following is the code that I have thus far:

#! /bin/csh
# This is the UNIX menu script file that is for the menu.

cat <<ENDINPUT

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

ENDINPUT
echo Please enter your choice:
read option

case $option
1.

I'm stuck at this point. What I am SPECIFICALLY looking for in option 1 is code that will prompt a user to enter another user's name and will then pull up that user's home directory. If the user does NOT enter anything, then their own home directory is displayed. What is the EXACT code that would accomplish this? Examples haven't helped me. Oh how batch files are much easier. I'm looking for the exact coding!!!

In option 2 I have to prompt the user to enter his or her name, and produce the following: Hello <person's name.>

I am desparate for help with this. Any help would be greatly appreciated. And again, I'm looking for EXACT code, not examples. Thank you.Smilie

tk::menu::item

Menu::Item(3pm) 					User Contributed Perl Documentation					   Menu::Item(3pm)

NAME

       Tk::Menu::Item - Base class for Menu items

SYNOPSIS

	  require Tk::Menu::Item;

	  my $but = $menu->Button(...);
	  $but->configure(...);
	  my $what = $but->cget();

	  package Whatever;
	  require Tk::Menu::Item;
	  @ISA = qw(Tk::Menu::Item);

	  sub PreInit
	  {
	   my ($class,$menu,$info) = @_;
	   $info->{'-xxxxx'} = ...
	   my $y = delete $info->{'-yyyy'};
	  }

DESCRIPTION

       Tk::Menu::Item is the base class from which Tk::Menu::Button, Tk::Menu::Cascade, Tk::Menu::Radiobutton and Tk::Menu::Checkbutton are
       derived.  There is also a Tk::Menu::Separator.

       Constructors are declared so that $menu->Button(...) etc. do what you would expect.

       The "-label" option is pre-processed allowing ~ to be prefixed to the character to derive a "-underline" value. Thus

	   $menu->Button(-label => 'Goto ~Home',...)

	   is equivalent to

	   $menu->Button(-label => 'Goto Home', -underline => 6, ...)

       The "Cascade" menu item creates a sub-menu and accepts these options:

       -menuitems
	   A list of items for the sub-menu.  Within this list (which is also accepted by Menu and Menubutton) the first two elements of each item
	   should be the "constructor" name and the label:

	       -menuitems => [
			      [Button	   => '~Quit', -command => [destroy => $mw]],
			      [Checkbutton => '~Oil',  -variable => $oil],
			     ]

       -postcommand
	   A callback to be invoked before posting the menu.

       -tearoff
	   Specifies whether sub-menu can be torn-off or not.

       -menuvar
	   Scalar reference that will be set to the newly-created sub-menu.

       The returned object is currently a blessed reference to an array of two items: the containing Menu and the 'label'.  Methods "configure"
       and "cget" are mapped onto underlying "entryconfigure" and "entrycget".

       The main purpose of the OO interface is to allow derived item classes to be defined which pre-set the options used to create a more basic
       item.

BUGS

       This OO interface is very new. Using the label as the "key" is a problem for separaror items which don't have one. The alternative would be
       to use an index into the menu but that is a problem if items are deleted (or inserted other than at the end).

       There should probably be a PostInit entry point too, or a more widget like defered 'configure'.
