Hallo zusammen,

habe ein kleines Perlscript, dem man ein paar Parameter mit auf den
Weg geben kann.
Nun moechte ich, dass wenn man
script.pl -?
eingibt, ein kleiner Hilfetext kommt.

Muss man das komplett selber programmieren, oder reicht es, den
Hilfetext mit einer
bestimmten Syntax im Script einzubauen und das Script macht es dann
"alleine"?

Gruss, Astrid

Beispiel:

#!/usr/bin/perl

use strict;
use warnings;

use Getopt::Std;
use Data::Dumper;

our %opts;
getopts( '?' => \%opts );

print Dumper \%opts;

if ( $opts{'?'} ) {
    print "Hilfe: $0\n";
    exit;

}

print 'done...';

Besten Dank.

Verstehe nicht, was der Dumper da macht?

Gruss, Astrid

Der ist einfach nur für die Debugging-Ausgabe da - um zu zeigen was in %opts steckt.
