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.

Answer 1

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
