I love having long options because it provides a better description of what the options are when someone views your program for the first time. It simply is a great user interface tool when someone comes across on of your scripts for the first time.
I start every new command line perl script with this template...
#!/usr/bin/perl
use strict;
use warnings;
use Getopt::Long;
use Pod::Usage;
Getopt::Long::Configure("no_ignore_case");
GetOptions(
'h|help'=>
sub { pod2usage( { -verbose => 1, -input => \*DATA } ); exit;
+},
'H|man' =>
sub { pod2usage( { -verbose => 2, -input => \*DATA } ); exit;
+},
);
__DATA__
head1 NAME
=head1 SYNOPSIS
Options:
-h --help Display this help
-H --man Display detailed help (examples)
=head1 EXAMPLES
=head2 First Example...
