decided to add this as a seperate node

This is the starting point I've got so far:

#!/usr/bin/perl -w

use strict;
use diagnostics;

my %cmds;
my $rgx;
my $sub;

$cmds{qr/^\s*quit/}  = \&quit;
$cmds{qr/^\s*cmd .*/}  = \&cmd;


my $txt = "cmd 12   arg2";


foreach $rgx (keys(%cmds)) {
        if ( $txt =~ /$rgx/i ) {
                $sub = $cmds{$rgx};
                &$sub($txt);
        }
}


exit;


sub quit {
        print "called quit\n";
}

sub cmd {
        my ($cmd, @argx) = split /\s+/, $_[0];

        print "called ".$cmd." with ".$argx[0]." ".$argx[1]."\n";
}
