Hello esteemed monks. :)

I have a script that I use Getopt with to call certain loops. It looks like so: 

use Getopt::Long;
use strict;
use Data::Dumper;
use IO::File;

my ($read,$generate,$help); # option switches
GetOptions (
    "help" => \$help,        
    "read"  => \$read,
    "generate" => \$generate,
);

Each one just points to a script that I put in an if loop, like so: 
if ($read) {
 - code snippets -
}

I added a few extra switches for single characters, like so: 
my ($read,$generate,$help); # option switches
GetOptions (
    "h" => \$help,
    "help" => \$help,   
    "r" => \$read,     
    "read"  => \$read,
    "g" => \$generate,
    "generate" => \$generate,
);

What I'm curious to know is if there's a better way to do this. Right now running 'scriptname -read' or 'scriptname -r' do what I'd like them to do, but, for example, while 'scriptname -generate' does the same as 'scriptname -g', 'scriptname -gen' fires me back an unknown option error.

I'm assuming that I need to somehow use (chomp, perhaps?) on the input to just snip whatever the -option is down to the first letter, but I'm not familiar enough with Getopt to know how to accomplish this.

Any advice is as always really appreciated, and thanks again to everyone on here for all the help you've given me so far. :)
