There is also a select command for BASH to build menus. Here is a example
The select command allows you to create bash script with menus. The select command uses the PS3 value for the prompts. Each menu items is separated by spaces in a variables as you can see in my OPTIONS variable. The beginning of the command is select a variable name for checking the options and a list of menu options. For example: select any_variable_name in menu_options. If you do not add break commands within the select command it will be a infinite it loop and you have to terminate using ctrl+c. Below I have posted a example of using the select command.
when the file is not found i want it to return to the menu, however it carries out the next line when i hit a key
I know its probably something simple can anyone help?
here is my pause function:
function pause(){
read -s -n 1 -p "Press any key to return to Menu . . ."
echo
}

tk::menu::item
Menu::Item(3) User Contributed Perl Documentation Menu::Item(3)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'.
