Why did you ignore the hint to avoid <pre>-Tags around your post?

Did you only think about the given code, or did you try it?

You also could have a look at Getopt::Long, which explains what happens, if an option doesn't have its optional argument...

Another possibility is something like this:

#! /usr/bin/perl # vim:ts=4 sw=4 sts=4 et nu fdc=3: use strict; use warnings; use Getopt::Long; my $x = "unset"; GetOptions( 'x:s' => sub { $x = $_[1] ? $_[1] : 'true' }, ) or exit 255; print "$x\n";

It's up to you to refine the checks and values to fit your needs.

added:

$ perl /tmp/getopt.pl unset $ perl /tmp/getopt.pl -x true $ perl /tmp/getopt.pl -x foo foo
