Unable to parse command line long options

Question

#!/usr/bin/perl -sw
use strict;
use warnings;
use Getopt::Long;

my $remote = 0;
my $test = 0;
GetOptions ('remote' => \$remote, 'test' => \$test);
print "$remote:$test\n";

perl test.pl --remote --test

The above prints "0:0". I am new to Perl so I have been unable to determine why this isn't working.

I also ran the "Simple Options" section from http://perldoc.perl.org/Getopt/Long.html#Simple-options and that didn't produce anything either.

I believe the -s command line option you include on your she-bang line is biting you. According to the perlrun documentation, the -s command line option:

enables rudimentary switch parsing for switches on the command line after the program name but before any filename arguments (or before an argument of --).

If you remove that option, things should work as you expect. I would also recommend removing the -w since you are already using the use warnings directive (the use warnings directive is much more fully featured, essentially replacing the -w option).

So, long story short, make your first line:

#!/usr/bin/perl
